Caterpillar’s trucking it out of Peoria...what does it mean?

If you were sick of the political back and forth and totally divested yourself from TV and the Internet the last few weeks, you might have missed the news that Caterpillar, the Peoria, Ill. behemoth, is moving its headquarters to Chicago, a few hours by car (and a good bit longer by construction truck, I assume) up the highway.

Caterpillar is what many people think of first when they hear “mobile hydraulics,” and with good reason. The company, with reported revenues of $38 billion last year and nearly 100,000 employees across the world, is an icon, with its machinery easily visible on construction projects, in mines, and along highways—not to mention a leader in hydraulic development and research.

But Caterpillar, too, has been synonymous with Peoria, a Midwestern town known for … well, its typical-ness. Groucho Marx popularly asked “Will it play in Peoria?” and rock stars, politicians and corporations have long used the city as a testing ground of sorts before expanding their reach to both coasts.

So why leave? Executives have expressed a desire to be closer to a world-class airport, which Chicago certainly has in O’Hare. And like Boeing’s move from Seattle to Chicago, there’s probably more than a little bit of a panache that a Chicago or New York or San Francisco address has—that an Omaha or Cincinnati or Rochester doesn’t. Chicago, too, surely has a lot more to offer potential new executive recruits, for when Caterpillar is looking to hire in its upper ranks. And that’s primarily what Chicago will be to the company. Headquarters will merely be the topmost executives and their direct support staff. The company says as many as 300 employees will eventually end up in the Windy City. Luckily for Peoria, the vast number of the company’s jobs currently located there are expected to remain put.

Years ago, a very large company I was covering hired a new CEO from a distant state. Not long afterward, the company announced that it was moving the entirety of its headquarter operations to that same state. What an odd coincidence! While this Caterpillar announcement doesn’t leave that sort of taste in my mouth, I do wonder what it means for so many other mid-sized and large manufacturers headquartered in the Toledos of the world. Will they all eventually be forced to relocate to the biggest of the big cities in order to remain competitive? Or is this nothing more than the latest business fad?

Toilet-gender politics derails fluid-power research There’s general agreement that money spent wisely on research often pays dividends down the road. As in other areas, R&D investments in fluid power can lead to technology advances and better products that benefit users, expand markets and improve the competitiveness of the industry.

Much of the precompetitive fluid-power research in the U.S. is overseen by the Center for Compact and Efficient Fluid Power, which currently supports projects at a number of universities. However, the CCEFP is transitioning to a new strategy: attracting government R&D dollars to finance future projects. “Instead of directly funding research, we can effectively leverage money for our Center into much larger sums in federal funding,” explained Kim Stelson, the Center’s director.

One of its first initiatives involved prevailing upon the Dept. of Energy to fund a program to improve the energy efficiency of off-road vehicles through new fluid-power technology. Proponents had to show DoE officials that mobile equipment has substantial unrealized energy saving potential.

And better fluid-power systems can improve efficiency by at least 30% over current systems using techniques like energy storage and waste-heat-recovery, hybrid architectures and machine automation. In the end it would lead to major fuel saving, lower operating costs, and large emissions reductions.

With DoE convinced, officials from the Center then lobbied influential House and Senate members for needed funding. The hard work seemingly paid off last spring as Congress, in principle, agreed to add a $5 million appropriation to the federal budget for the new off-road/ fluid-power research program. In terms of government spending $5 million is a very modest amount, said Stelson.

“But this would be a huge shot in the arm, for both academia and industry, for research in this area.”

Everything looked good until, out of left field, came the controversy surrounding transgender bathroom access in North Carolina. A last-minute rider attached to the budget legislation said the federal government couldn’t dictate bathroom access policies to states, and the ensuing uproar effectively killed the entire $1.1 trillion bill.

Congress instead passed a continuing resolution that merely maintained the status quo and didn’t consider new programs. The budget was to be revisited in December, but after the election Congress kicked any decision down the road to this April. Stelson feels the fluid-power segment of the legislation still fares well, although if negotiations break down again nothing will change until October, and another fiscal year will be down the drain.

Fortunately, not all the Center’s efforts are in one basket. They’re also working on attracting government funding from existing programs related to human-scale fluid-power research and emerging manufacturing technologies. For example, the Dept. of Defense recently announced an $80 million grant to the Advanced Robotics in Manufacturing (ARM) Institute that includes CCEFP researchers.

Nonetheless, Stelson isn’t close to giving up.

“We’re about to launch a new lobbying campaign for renewed support on Capitol Hill for both fiscal years 2017 and 2018,” he said. In his eyes, healthy investment in R&D is just too important, as it presents a huge opportunity for future growth in the fluid-power industry.

Right-sizing components decreases compressed air waste, increases productivity After a soft launch of its Air Saver Unit (ASU) this past year, Parker Hannifin is now promoting that the device also promises plant productivity gains on the factory floor.

Introduced from Parker Japan last year, the ASU allows users to eliminate the air that is wasted during constant use when blowing off chips, agitating products, PET bottle transfer, cooling, and cleaning, says Rick Hand, marketing program manager for Parker’s Pneumatic Div. North America.

“What this does is integrate a timing module into a directional control valve and it allows us to set a pulse rate that we can tune and adjust to the application so that we can go ahead and save that extra air,” Hand said. This could save up to 50% of wasted compressed air. And even if you’re only saving 10%, at 30,000 in.3, that’s a lot of air.

It is an energy-saving device, and more, Hand said.

“What’s interesting to us is we’re selling it as an energy-saving device, but we’re seeing productivity improvements at the customer level, because you can control the pressure, flow, and pulse to give you more, give you less, versus just having a constant.”

Through manual adjustment, ASUs can save energy by interrupting compressed air flow. These series of impulses are mechanically more advantageous because the ASU can recover during the “off” period of each on/off cycle. Thus, the air impulses are delivered with greater force than a steady stream of air.

“For years, Parker has promoted good sizing practices, air audits, things that you can take onto the plant floor and look at as a way to save some money, because compressed air can be expensive if you’re not careful with it.

We tend to add on and add on to a pneumatic system and the efficiency goes down and down and down as we do that if we don’t really pay attention,” Hand said. “The simple things in life sometimes are the things that are really beneficial. And when Parker came up with the Air Saver, it was like, ‘Why didn’t we think of this sooner? This is a no-brainer.’”

The Air Saver is available in port sizes ranging from M5 to 11⁄4 in. (5 to 530 cfm flow). Control is done through a pneumatic control or a solenoid version, said Hand. The device allows for adjustable pulse frequency and duty cycles. Additional features include a silicone-free grease version for paint shop applications and an on/off time adjustment needle.

To promote the productivity enhancements current users are seeing, Parker has updated its compressed air cost apps to help calculate the value this device can bring to an application, said Hand.

A collection of 15 new cost calculators, conversion tools and air valve (Cv) and flow (scfm) calculations for air cylinder actuation is now available from Parker to determine everything from what a compressed air leak can cost you to how to properly size a component for your application.

“We took a look at what we’ve been doing for years with Excel spreadsheets and slide rules and all the other various methods for calculators and put it in a mobile platform,” Hand said. “We did add a value calculator for the Air Saver where if you know your orifice, your cycle and how long it’s going through the day, and if you understand what your electrical rate is, you can go ahead and do the calculations. The answer coming down to it really is going to give you what your footprint is, going to tell you how much CO2 you’re saving and all the things that go along with it.”

Parker Hannifin’s Air Saver Unit reduces wasted air by switching from constant use to pulsed air flow when blowing off chips, agitating products, PET bottle transfer, cooling, cleaning, and more.

Parker is currently working with electrical companies in the Pacific Northwest that are evaluating and proofing the value calculator, so that customers can obtain energy credits by using the ASU, Hand said. He expects that verifiable data will be available to promote in the next six months.

While this allows companies to be green, it also gives them easy and clear access to the supply chain. By knowing exactly what cylinder a user requires, it is easy to determine what valves, FRLs or any components are suitable, too.

Additionally, users can find out what is in stock, costs and lead time all through this mobile platform. “Ultimately, it comes down to efficient design, that’s what we’re really pushing and promoting here,” Hand concluded.

The suite of 15 tools includes the following compressed air electricity cost calculators: • Cost calculator for leaks • Cost calculator for compressors • Cost calculator for compressors <100% lead time (operating at less than full load) • Air flow through an orifice • Vacuum flow through an orifice

In this application, pulsed air is used to remove swarf, the metal shavings that result from tooling metal with a cutting tool.

• • •

Cost calculator for reverse flow regulators Annual cost of air cylinder operation Pulse blow air saver

Two additional apps calculate cost savings when using air economizing on vacuum and determine storage tank (receiver) size and capacities.

Four valve/FRL sizing programs are also included: • Valve/FRL sizing for cylinder actuation • Cv if air flow Q (scfm) is known • Air flow Q (scfm) to atmosphere • Air flow Q (scfm) if Cv is known A final tool helps convert millimeters to inches, pressure of bar to psi and Nl/min to scfm.

The apps can be found and downloaded from the iTunes and Google Play stores by searching for “Parker PDN.” A desktop version is available at www.parkerpdncalc.com.

Forum Energy Technologies wanted to incorporate an emergency stop at the front of the tool where the operators work to make the shutdown feature easier to access.

Doering valves increase safety of industrial machinery Safety is critical in any application where workers interact with machinery and companies need to make these environments as safe as possible. Houston-based Forum Energy Technologies sought to improve the safety of its FloorHand iron roughnecks, widely used in the oil and gas industry for pipe handling. The original machine design had a safety system in place on the back side of the tool.

“We wanted to incorporate an emergency stop at the front of the tool where the operators work, to make the shutdown feature easier to access,” said Keith Jarvis, Forum Energy Technologies product specialist.

The company worked with hydraulic distributor Hydradyne LLC in Texas to add an emergency stop valve.

Emergency stops are crucial for machinery like the FloorHand because the high-power tools are manually operated and conditions are harsh. Acids and corrosives are used in the drilling process to maintain the wellbore integrity. If these chemicals have 16

prolonged exposure to a hose, the hose could potentially fail and result in a high-pressure oil leak. The emergency stop valve at the operator’s panel will immediately contain and stop a leak.

Additionally, operators work in close proximity to the machine, which uses 80,000 ft-lb of torque to thread pipes together up to a mile long, in 30 to 90-ft. sections. Its operating pressure is 2,500 to 2,800 psi. If a hand or piece of clothing gets caught, instant shutdown is critical.

The distributor chose the stainless steel version of Doering’s manually-operated, three-way cartridge valves because of its ability to withstand the corrosive elements of the application. When the large knob on the valve is pressed, it instantly stops the machine by engaging a latching feature. This ensures that all hydraulics available to the machine are isolated, and places the machine in safety mode.

“Because of the harsh conditions on the rig, a stainless steel valve was the only solution that would work reliably as an emergency stop,” said Ron Holcomb, Hydradyne technical sales.

In one application, an LPG gripper was attached to a pick-and-place mechanism. “L shaped” fingers attached to the gripper jaws are positioned over a product conveyor in an automated shipping system. As each product passed under the gripper, the “L-shaped” fingers stopped it.

The fingers then grasped the product by clamping on its island area on top. Next the product was lifted, carried over to the carton positioned on the adjacent shipping 18

Only the LPG’s cantilevered design permits the gripper jaws to be positioned as required without interference.

Eight linear bearings support the stainless steel guide shafts. Cross-tapped holes on each jaw bar allow tooling attachments on any surface. The end caps are machined on both the top and bottoms surfaces allowing the gripper to be mounted with its port side up or down.

Options include magnetic position sensing, adjustable stops and bumpers.

Pneumatic safety brakes with hydraulics-level power

With the new pneumatic ROBA-guidestop, mayr power transmission provides an innovative braking concept which fulfills the high safety requirements and achieves high performance density without the use of hydraulics. Image: mayr power transmission.

Mayr power transmission recently set out to create a compact safety brake in a small construction space with high forces… and all this without using hydraulics. The result was a new, high-performance, pneumatically-released version of the ROBA-guidestop profiled rail brake.

This extended ROBA-guidestop series has a pneumaticallyreleased version which provides new possibilities with its high holding forces. For machines in which a hydraulic system is already available, users can still use the hydraulically-released ROBA-guidestop safety brakes. However, in applications where a hydraulics system would have to be installed first to operate a brake with high holding forces, the pneumatically-released ROBA-guidestop safety brake is now used. It clamps profiled rails accurately and backlash-free with the same holding forces as the hydraulic design of the brake.

The pneumatic ROBA-guidestop is opened with compressed air at 20 to 30 bar. To achieve the proper operating pressure, operators use a compact pressure booster in combination with the brake, mechanically increasing the system pressure from 4 20

to 6 bar as is usual in pneumatic networks, without the use of external energy. This concept enables a selective pressure increase directly prior to the brake, i.e. directly in the system where the higher pressure is required — as a result, short high-pressure lines suffice.

The pneumatic ROBA-guidestop safety brake is available in five construction sizes — each size in both a standard design and in a compact, short design — covering a range of holding forces from 1 to 34 kN. The brake is designed for the different rail construction sizes of conventional linear guidance manufacturers.

Safety Just like the hydraulic brake design, the pneumatic ROBA-guidestop safety brake acts with high rigidity directly applied to the linear guidance. This means that the safety brake is

mounted directly on the masses that should be held. This configuration reduces hazards, especially concerning gravity-loaded axes.

Drive elements between the motor and the moving mass, such as spindles, spindle nuts, shaft couplings or gearboxes, have no

influence on safety — as opposed to the concepts using motor brakes, where all drive elements transmit the braking torque to the carriage. Systems using ROBA-guidestop safety brakes therefore enable a significantly higher rigidity than solutions featuring rotary brakes integrated into servomotors.

Backlash-free clamping advantages: The additional rigidity of the NC axis increases process accuracy, improves machining performance and can provide

further technological advantages for heavy machining. The machining produces less vibration, improving workpiece surface quality.

In case of a stationary axis during machining, the brake can absorb the load. As a result, the drive motor can be switched off and removed from the controls. This eliminates control movements and is gentle on the ball screw spindle. The closed brake absorbs the axial forces. The service life and maintenance intervals of the drive components are extended.

The brakes of the ROBA-guidestop series operate according to a fail-safe principle, i.e. they are closed in a de-energized condition.

They reliably guarantee operational and functional safety in machines and systems around the globe.

How does a coalescing filter work?

Coalescing filter design from MFD Pneumatics

Large contaminants in a pneumatic system are readily captured by general-purpose filters or tend to settle out of a compressed-air stream. Air dryers can effectively remove water from compressed air. But aerosols—extremely small (≥ 0.1 micron) solid particles and liquid droplets of oil and water suspended in the air—remain in the flow stream and can cause problems downstream.

For example, these contaminants can hurt the performance of close-tolerance valves and instruments, damage seals, erode hose inner tubes and foul desiccant dryers. And they can adversely affect processes like paint spraying and contaminate end products such as food, beverages and pharmaceuticals.

Standard particulate filters do not remove most submicron contaminants. Coalescing filters, on the other hand, are designed to trap and subsequently remove submicron-size liquid oil and water and solid-particulate contamination from compressed air.

Coalescing filter elements have extremely fine fiber meshes that intercept and capture aerosol particles.

They amalgamate smaller particles into larger ones. Tiny 22

FLUID POWER WORLD

Fundamentals_FPW_2-17_Vs3 MG.indd 22

2 • 2017

liquid droplets are brought together into larger droplets as air flows through the element’s fiber matrix, and they eventually become large enough to be drained away.

Coalescing filter elements remove contaminants using three different mechanisms: Diffusion typically applies to particles 0.1 micron and smaller.

These are subject to random Brownian motion and they collide with and are trapped by the filter. Solids adhere to the filter membranes and liquids join with other droplets to form larger masses.

Interception affects particles about 0.1 to 1 micron in size.

Turbulent flow forces particles against the fibers, and they are captured in the filter matrix. Smaller pore size increases capture efficiency.

Direct impact applies to particles 1 micron and larger. Here, contaminants simply collide with and are trapped by the fibers.

www.fluidpowerworld.com

2/16/17 3:54 PM

FUNDAMENTALS

In a typical coalescing filter, air enters the housing and flows through the media from the inside to the outside of the filter element. Coalesced oil and water droplets collect on the filter fibers and, as they grow in size, migrate downward due to gravity.

The liquids collect in a bowl at the base of the housing and are subsequently drained away, while clean air exits the housing through the outlet port.

Coalescing filters also remove solid contaminants such as dirt, dust and rust from compressed-air systems. These particles are permanently trapped in the filter element, eventually restricting flow and blocking the filter media. So the volume, efficiency and degree of contamination of the incoming air help determine the useful life of the filter element.

In addition to common selection

parameters like pressure limits and flow capacity, the units are rated by filter efficiency—a measure of the percentage of contaminants of a specified micron size that the element captures. Filter ratings vary by product and can range from around 90% to more than 99.99%. Users generally should specify products based on the application requirements, because more-efficient filters typically cost more, have a higher pressure drop and shorter service lives.

How and where a coalescing filter is installed can also have a sizeable effect on overall performance and operating expense. Experts generally recommend installing a prefilter, such as a 3-micron unit, to remove as much as possible of the particles before it reaches the coalescer.

This can significantly increase the life of the coalescing filter.

If the compressed air in a process has various cleanliness requirements in different circuits, install coalescing filters only in point-of-use locations that actually demand extremely clean air. This saves money. Also note that coalescing filters will cause a 2 to 6 psi drop downstream, so factor the pressure loss into the equipment sizing and selection. And, as with other filters, replace them whenever they become clogged.

When pressure drop across the filter increases to 8 to 10 psi, that is an early warning sign that the filter is nearing its end of life and needs to be replaced.

Finally, note that coalescing filters do not remove oil vapor. Use activated-carbon or adsorption filters along with a coalescing unit when extremely clean air, such as breathing air, is necessary.

matches real-world conditions Thanks to higher operating pressures, power density in many hydraulic systems has increased significantly in recent years. That can mean higher performance, smaller and lighter components and better efficiency, although it can also increase the susceptibility to wear and premature failures. Newer pumps and motors are built to handle higher loads and still offer long life. However, the same isn’t always true for many hydraulic fluids. That’s because the type and quality of oil has a significant impact on component wear characteristics and, with it, an ever-increasing effect on the service life and reliability of hydraulic systems.

The problem is that higher pressures put greater stress on hydraulic oils.

Unfortunately, as fluid-power components and systems have rapidly evolved to meet tougher operating conditions, the standards for rating fluids have not kept pace. According to engineers at Bosch Rexroth, while pressures, temperatures and oil circulation rates have risen sharply, the minimum requirements of relevant standards like ISO 15380 and ISO 12922 do not reflect today’s higher demands for hydraulic fluids.

The result is that a high-performance circuit may run trouble-free with one fluid but quickly fail with another— even though both fluids meet the same standard.

Until now, machine manufacturers could only rely on arduous and expensive trial-and-error tests to find suitable fluids that meet their application requirements.

To address that, Bosch Rexroth recently developed a new evaluation method for rating hydraulic fluids that realistically reflects higher performance demands.

The procedure examines the behavior of lubricants and the interplay in key

www.fluidpowerworld.com

2/16/17 9:25 AM

RESEARCH & DEVELOPMENT components—the hydraulic pump and motor— under realistic working conditions, said Roland Schmidt, director of business development for construction and industry at fluids manufacturer Liqui Moly, based in Ulm, Germany. “The pump test introduced by Bosch Rexroth goes far beyond that which the current DIN and ISO standards require. Conventional tests work with 350 bar; the new standard up to 500 bar,” explained Schmidt.

As described in Rexroth data sheet RDE 90235, technicians assess the behavior of fluids and their interactions with core components under real-life conditions. The standardized procedure was initially developed and validated for A4VG series axial-piston hydraulic pumps as well as A6VM series hydraulic motors in closed circuits, as in hydrostatic drives.

The process begins with an initial breakin period, then components are subjected to high-pressure dynamic cycling where the pump and motor continuously swivel in and out. This regimen runs for 300 hours at 450 bar pressure, speeds of 4,000 rpm, and a temperature of 100°C. Next, a corner-power test gages the load capacity of components at maximum pressure and speed. It runs for 200 hours at 500 bar, 4,000 rpm and 100°C. For both segments, technicians examine shear-strain behavior, wear-protection properties and material compatibility, among other characteristics.

Rating criteria are based on component weight and dimensional changes before and after the tests; material compatibility, including visual inspection of components and component surfaces; and oil analysis at the beginning, during and end of the test. From this, technicians report conclusions on the long-term running behavior of the components based on the fluid. The evaluation procedure is suited for all mineraloil-based hydraulic media, environmentally acceptable media, as well as water-based and water-free fire-resistant hydraulic fluids.

Rexroth’s RDE 90245 document shows fluids that meet all the requirements. Currently, only four fluid manufacturers make the list: Fuchs, Liqui Moly, Shell, and SRS.

HyPER oils Liqui Moly’s HyPER products are among the first, worldwide, to meet the standard. Bosch Rexroth is a leader in hydraulic pumps and motors, and 2 • 2017

Demanding applications will benefit most, he continued, but HyPER hydraulic oils are also cost-effective in standard applications. Bosch Rexroth explicitly requires hydraulic fluids that meet the new RDE 90235 for all their pumps, as the old standards are obsolete, said Schmidt. HyPER SG1 also meets Parker Denison, Eaton, and other manufacturers’ specifications.

Liqui Moly’s HyPER fluids are suited for demanding applications.

Shell Tellus their new RDE 90235 is the toughest test available for hydraulic oils, said Roland Schmidt. “If an oil passes this test, it has proven its superiority,” he said.

“All Liqui Moly HyPER hydraulic oils are based on Group II base oils paired with a superior additive package,” he explained.

“These base oils are quite new in the hydraulic area but they provide much higher cleanliness and oxidation stability compared to standard hydraulic fluids. And the additive package had to be completely redesigned as available formulations were not capable to meet the unprecedented high requirements.”

This results in long-life characteristics that, in turn, help extend equipment

service life. “HyPER hydraulic oils are a great example of how you save a lot of money in the long run by investing a little more money in the beginning,” said Schmidt.

For example, they reduce wear to the nonferrous metals and the nitrate layer of pistons and bores. Intervals between oil changes significantly increase. The new additive package offers better elastomer compatibility compared to other standard hydraulic fluids, which means less leakage.

“Last but not least, we improved the cleanliness levels of our HyPER hydraulic oils. This will ensure from the beginning less wear and less failures of sensitive components like valves and pumps,” noted Schmidt.

Shell’s new Tellus S2 MX hydraulic oils also meet RDE 90235. “Shell is always striving to help our customers lower their total cost of ownership,” explained Rob Profilet, the company’s product application specialist for industrial products in the Americas region.

Bosch Rexroth developed this new approval procedure to meet the trend toward equipment operating at higher pressures and higher speeds, he said. “There are a lot of good specifications out there, but this one moves the envelope in terms of severity. It’s a difficult test to pass and we’re one of the first with the approval,” he stressed.

The fluids are designed for higher load-carrying capacity and excellent wear protection, even under severe operating

RESEARCH & DEVELOPMENT conditions. Tellus S2 MX uses a Group II base oil formulation that extends oxidation life compared with previous products based on Group I base oils, said Profilet. And significantly, to meet the rigorous pump-test criteria, the additive chemistry had to be specially designed for enhanced antiwear performance while, at the same time, balance other attributes such as water-separation ability and thermal and oxidation stability.

They’re priced competitively with other typical hydraulic fluids, he said, but designed to last longer. In terms of total cost of ownership, users can extend oil-drain intervals, use and dispose of less oil over the longer term and, thanks to enhanced antiwear performance, better protect components and likely replace them less often.

“And it’s not just for demanding applications. It’s for use really across the board in hydraulic systems, anywhere you

would typically use a mineral-based hydraulic oil,” said Profilet. Equipment running on Tellus S2 MX fluids can have smaller reservoirs, operate at higher loads and temperatures, and offer longer change intervals, with less downtime and better efficiency. Shell also offers a multigrade version called Tellus S2 VX, he added. It includes a viscosity index improver for operation across a wider temperature range, such as in outdoor applications. It is currently in the process of meeting RDE 90235 approval.

The Rexroth test lets manufacturers of lubricants and additives have the performance of their hydraulic fluids rated independently, regardless of the application. Suitable fluids can substantially lengthen the service life of hydraulic components and significantly lower the odds of failure. As a result, machine

The business end of hydraulics: the cylinder Retract Flow Port

Extend Flow Port

Piston Rod

Piston & Seals

This article will talk about the business end of the hydraulic system: The force produced by the cylinder. When using a standard double-acting cylinder, there are three internal areas of concern: • Piston area = transfer fluid pressure to force to extend piston rod • Net piston area minus piston rod area • Rod area = significant when cylinder is used in regenerative action To calculate cylinder force against a load, two calculations are required: • Force over piston area • Opposing force over opposing piston area For example: • Extension force is 50 psi x 20 in.2 = 1,000 lb.

• Opposing force on rod side is 30 psi x 18 in.2 = 540 lb.

The net force the cylinder can exert against a load in the extension direction is: 1000 lb – 540 lb = 460 lb It is important to remember and calculate in the added pressure required due to packing friction, which in standard cylinders can amount to 5% (let’s say 10%, to be safe) of the maximum force for which the cylinder is rated. This extra power is consumed when the cylinder is in motion.

Cylinders are designed to move various types of loads:

Vertical gravity load—a non-friction load that requires full cylinder force to be produced throughout the stroke. Additional force will be required and calculated in to accelerate the load and to overcome loss due to supply flow and friction losses.

Stall-out load—in cylinders that are used on either vertical or horizontal presses, when the press contacts the work piece the cylinder stalls. During cylinder piston movement, they usually run in “free traverse” for most of the stoke. During free traverse, very little pressure is required on the cylinder piston and the pump supplies only the hydraulic circuit losses due to fluid flow friction.

At stall, all fluid flow friction disappears. When calculating pressures required at the cylinder port, allow 5% for packing friction losses even with no movement through the packing.

Horizontal friction loads—horizontal cylinders can be used for either push or pull applications.

The force required for moving a load horizontal is less than the force required to lift it. To calculate for a horizontal load, you have to calculate the load times the static coefficient of static friction (resistance to movement created by molecular attraction between load and surface materials)

Static coefficient of materials can be obtained from a machinery handbook.

Rolling loads—we all know how much a wheel makes it easier to move an object across a surface. By replacing sliding resistance with rolling resistance, you require a significant amount less force. With rolling load, there will be a breakaway force required to set the load in motion; a force as little of 1⁄10 the load will break away the load and then even less force is required to keep the load in motion. The breakaway load is caused by the wheel as it applies a force on the surface material. The displaced material from under the wheel is pushed out in front of the wheel. As the wheel moves across the surface, it continually displaces the surface material to the front of the wheel creating the rolling resistance. If you roll a wheeled chair across the carpet, you can

see the carpet bulge up in front of the wheel. Even though we are rolling hardened steel across a steel surface, the steel will act just like the carpet.

Use the following calculation:

T

W L A (area to be sheared) = (L + W + L + W) x T All dimensions must be in inches

Punching loadsâ&#x20AC;&#x201D;the cylinder application is used to punch, shear or notch a work piece.

After calculating the number of square inches of metal to be sheared, multiply that number times the shear strength of the material. This gives the cylinder force needed to make the cut.

Shear strength for metal can be assumed to be about 75% of the metals rated tensile strength and is expressed in psi. For accurate shear values, consult the supplier of the material.

IFPE coverage on the ground and online One of the most important events on the fluid power calendar is the triennial IFPE show, held in conjunction with CONEXPO-CON/AGG at the Las Vegas Convention Center. These sprawling shows attract well over 100,000 visitors with each iteration, with exhibitors and attendees coming from all over the world. This year’s IFPE will run from March 7-11.

I’ve been attending this event since the 1996 IFPE at Chicago’s McCormick Place—where does the time go?!—and I can attest to the importance of attending this fluid power mega-show.

Our staff at Fluid Power World and Design World will be reporting on IFPE like never before, with detailed coverage in print, online, through social media, and at the event itself.

This special section on IFPE has a detailed rundown of the must-see aspects of the show, an exhibitor list, an overview map and some special sections on selected fluid power components— where they’re used and what you need to know to look for, if you’ll be investigating them at this year’s event.

When you’re in Las Vegas, I hope that you’ll come by our booth, S83257. Our editors will be filming videos with some industry leaders right at the booth, and we invite you to come by, and watch or get in on the action. We want to hear from you—what are you seeing at the show, what technologies are most exciting to you, what challenging new designs are you working on?

THE TRIENNIAL SHOW, CO-LOCATED WITH CONEXPO-CON/AGG, RETURNS MARCH 7-11.

History In 1984, the National Fluid Power Association held its first Chicagobased fluid power show under the title International Fluid Power Exposition. Held every four years, that show periodically partnered with other events like Motion Expo and the International Welding and Fabrication Expo. By the year 2000, the NFPA no longer felt the title accurately reflected the scope of their event. The name was changed to “IFPE — International Exposition for Power Transmission” to better represent the integration of fluid power with electrical and mechanical components and systems. Two years later, IFPE also began co-locating with CONEXPO-CON/AGG, the largest international gathering place for the construction industries. The collaboration between the two shows ushered in two other large-scale changes as well: a move to Las Vegas and the show’s current three-year cycle.

Mon. March 6 | 8:00 AM - 12:00 PM Fundamentals of Hydraulic Systems #CC1, Presented by Dr. Medhat Khalil, Director of Professional Education, MSOE This presentation is made to increase the awareness of the audience about the fundamental concepts of fluid power technology. The presentation covers some rules of physics about fluid pressure and flow. The lecture then presents the generic structure of a hydraulic system in addition to construction and principle of operation of the main components, e.g. pumps, motors, valves, cylinders, and rotary actuators. The session concludes with details on how to combine all these components into a system that works safely and efficiently.

Mon. March 6 | 1:00 PM - 5:00 PM Hydraulic Fluid Properties, Efficiency and Contamination Control #CC2, Presented by Paul Michael, Research Chemist, MSOE In this seminar participants will learn about the composition of oils, the properties of lubricants and how hydraulic fluids can affect machine performance. Conventional, multigrade, synthetic and biodegradable fluids will be discussed. Research studies examining fluid efficiency effects in hydraulic motors and piston and gear pumps will be presented. The principles of oil analysis and filter selection will be outlined. The seminar concludes with case studies that demonstrate how filter debris analysis can be used to troubleshoot hydraulic system contamination control problems.

Education — college courses IFPE 2017 will be filled with educational opportunities. These education events provide crucial information on new fluid power, power transmission and motion control technologies to engineers and others involved in the design and manufacturing process. They provide hands-on technical knowledge for the effective use of hydraulics in mobile equipment. These half-day courses will benefit practicing engineers and others involved in the design and manufacturing processes. Additional costs apply.

Tech Experience From solar-powered roadways, to data visualization and interactivity, to the first-ever 3D printed excavator, drones, robotics, and intelligence advancements, the Tech Experience is a 75,000 square-foot immersive, future-forward showcase that lets attendees see what’s possible tomorrow and today. The Tech Experience is included in attendees Badge-Packs.

Hydraulic excavators are a mainstay at Conexpo. They come in countless versions and, while most are commercial products, sometimes OEMs also offer a glimpse of the future. At this year’s Conexpo, one machine of tomorrow that’s worth a look is the Additive Manufactured Excavator. It includes a 3D-printed steel boom with built-in hydraulic passages that eliminate hoses and improve cooling. It will also include a printed cooling system that will increase efficiency and reduce weight. The excavator will feature a futuristic cab designed by the student engineering team from the University of Illinois at Urbana-Champaign.

The purpose of the excavator project is to demonstrate two emerging technologies: large-scale composite additive manufacturing and large-scale metal additive manufacturing. It is the first time steel is being used in 3D printing on such a large scale. This was done to prove that both metal and composite additive manufacturing have a place in the manufacture of construction equipment.

How are hydraulic valves used on mobile machinery?

Hydraulic valves govern direction, pressure and flow of hydraulic fluid, enabling smooth, safe and controlled use of actuators. They can be as simple as a relief valve to protect your pump and actuator. Or, their use can be complex, like when using a dozen valves in manifolds, such as a pilot operated valve with dual counterbalance valves, dual flow controls, dual post-compensation and load sensing checks.

The directional control valve’s function is to control the path of fluid flow. The most basic design is the check valve; it allows flow into one work port, and blocks flow from coming back through the opposite work port. They can also be as advanced as pilot operated proportional valves with internal pilots, drains and load sense check valves.

Directional valves are often described as the number of “ways” fluid can travel through itself, and also by the positions available to be shifted into. The ways are equal to the number of work ports, so a 4-way valve will have pressure, tank and A and B work ports. Positions are equal to the number of positional envelopes. For example, one would describe a double acting single-monoblock valve as “4-way, 3-position,” or simply a “4/3 valve.”

Monoblock or sectional directional valves are common to the mobile-hydraulic industry, as well as subplate mounted industrial type valves such as ISO style D03s, D05s et al. Also common to mobile and industrial markets are cartridge valves installed into manifold blocks.

Cartridge valve manufacturers offer many unique products, and allow high levels of creativity with limitless available valve combinations.

Pressure valves are designed to in some way limit pressure. Most designs are based on a poppet being pushed against a seat with an adjustable spring. A relief valve controls maximum pressure for the entire system or a sub-circuit of it, the lowest spring pressure being the first to open up. Other pressure valves are based on the relief valve’s simple 60

Hydraulic Valves_IFPE_Vs2 MG.indd 60

spring-loaded ball or poppet. Sequence valves, counterbalance valves, and brake valves offer added utility or functionality, such as reverse flow checks or pilot operation built in. Pressurereducing valves differ from other pressure valves because they limit pressure downstream, rather than upstream. They are used where subcircuit pressures need to be lower, without sacrificing performance in the rest of the system.

Flow control valves are designed to control or limit flow in one way or another. Often simply a needle valve—which is just a variable restriction—it is adjusted by a screw or knob to limit energy potential to create flow. When installed with reverse flow check valves, we change the name to flow control. Flow control valves can have multiple ports, such as with a priority flow control. They can provide controlled, fixed flow to one part of the circuit, sometimes at the sacrifice of another part, and as long as input flow is high enough for its priority demand.

Flow controls are ideally pressure compensated, which allows them to maintain set flow regardless of load-induced pressure variances.

Pressure compensators are a type of flow control valve available as a single item, often added to other valves in a circuit to provide the same flow setting load-independent accuracy, such as with a proportional valve, for example.

What types of hydraulic cylinders are used on mobile machinery?

Mobile machinery is rife with hydraulic cylinders, particularly for

use on buckets, shovels, booms and other tools and attachments on machines like backhoes, excavators, telehandlers, cranes, balers, skid steer loaders, dump trucks and more. These machines and attachments use hydraulic cylinders to push, pull, lift and lower loads that other might otherwise be impossible to move with lesser force technologies.

Cylinders are responsible for converting hydraulic power into linear motion to do work or move a load by applying pressure to the cylinder’s piston. These somewhat simple devices usually feature a basic construction, including the aforementioned piston inside a cylindrical or rectangular tube or body, end caps and housings, as well as necessary bolts, nuts, plugs, bearings, rod seals and wipers, and more.

The two most common designs used on mobile equipment are welded-tube and tie-rod cylinders. Welded cylinders are constructed of a heavy-duty tube that is closed off with a welded-on cap. Mounting anchors, including trunnion, side lug and side tapped, clevis, bolt, and flange types, are usually attached to the welded cap. A threaded gland on the rod end allows these cylinder types to be easily repaired.

The simpler, but less durable tie-rod cylinder is designed with bolts and tie rods that hold two castings on each end of the barrel together.

Also easy-repairable, this cylinder design is common on agriculture equipment and is often used on NFPA or ISO cylinders.

Hydraulic Cylinders_IFPE_Vs3 MG.indd 62

To determine a cylinder’s mechanical force, one must know the diameter of the piston and use the following formula to give you the linear force of a cylinder. First, convert the piston diameter into area by using πr2 then multiply area by your chosen pressure unit.

Pressure x Area = Force Differential cylinders are the most common hydraulic cylinder design. Because they feature a rod in just one end, the force created when retracting is not equal to that created when extending. In retraction, a differential cylinder has less area for pressure to work upon because of the space taken up by the rod. Consequently, a differential cylinder will retract with more velocity than it extends, given equal flow at either service port. Once again, this effect is a result of the space taken up by the rod—in this case, filling up the reduced volume more quickly. The force reduction resulting from the rod location is inversely proportional to the flow increase

from the same cause. For example, if the area of the cap side of the piston is twice that of the area from the rod side of the piston, it is referred to as a “two-to-one” cylinder. This cylinder will extend with twice the force than in retraction, and retract in half the time as extension.

Differential cylinders are normally double-acting, i.e., they are powered in retraction as well as extension. A differential cylinder can be powered in just one direction, if required, which is called single-acting. A single-acting cylinder is manufactured in various forms, and normally when a differential cylinder is used as single acting, it will have a breather at the non-powered port to avoid trapped air. Single-acting cylinders are sometimes spring loaded, and are important if the mass of the load isn’t enough to push the fluid back through valves alone. Springs can be added to either the cap or rod end of a cylinder, enabling spring-extend or spring-retract functions respectively.

Single-acting cylinders can also be rams, which are cylinders consisting of just a rod in a tube. Pressure pushes the ram up or out, but often requires energy to retract. This energy can come from the mass of the load, but sometimes is generated from springs or other devices that are part of the machine itself, rather than inside the cylinder.

Another common cylinder species is the telescopic variety. These cylinders use multiple-sections that are both bodies and rods, and can extend far longer than their retracted length would suggest. They are relatively compact and can usually extend twice their retracted length.

How is hydraulic hose used on mobile machinery?

Because it is impossible to physically stack every component of a hydraulic system like a Jenga tower, plumbing is required to direct hydraulic energy through the circuit. Pipe, tube and hose are required to channel fluid through the system, and the requirements of the system must be reflected in the choice of conduit.

Hydraulic hose is the most commonly used conduit, especially on mobile machinery, and is mandatory should any bending or movement in the mechanism require it. Hoses feature a multi-layer construction, most often with synthetic rubber such as Nitrile and strengthened with braided steel, although synthetic and textile braids are used as well.

The pressure rating of hydraulic hose is a result of the number of braid layers and the nature of their construction. The SAE has created standards for hose construction, which dictate specifications for pressure, temperature and type of fluid being used. As you would imagine, the more layers of braided material used, the higher the pressure the hose can withstand. Consequently, hose with four or six layers of steel braiding is quite stiff, so consideration should be taken for bend-radius requirements when choosing hose.

Consideration should be taken for diameter when selecting hose to ensure pressure drop remains in check; pressure drop is so often overlooked in a hydraulic system, and the energy wasted can be extensive. However, just as the layering of braids can affect 64

FLUID POWER WORLD

Hydraulic Hose_IFPE_Vs2 MG.indd 64

2 â&#x20AC;˘ 2017

the rigidity of hose, so too can its diameter. Hose manufacturers publish the bend-radius of their hose, and most manufacturers carry a short bend-radius hose in their product line, although it is often more expensive.

Specialty hose is available for demanding applications, such as for use in high heat or with exotic fluids. Steel braiding in a hose transmitting high water-based fluid is bad news, as internal corrosion will occur and will go unnoticed. Hose can also be had with non-conductive construction, to ensure the hose does not transmit electricity when installed on a machine working on electrical utility jobs.

The most common hydraulic hose is the 100R1 and 100R2 construction types, with one or two layers of braided steel respectively. These hose types are not suitable for every application, so consult with industry professionals when choosing your hydraulic hose.

How are seals used on mobile machinery?

Seals are the unsung heroes of the fluid power industry; they work hard in nearly every conceivable pump, valve or actuator, providing function, efficiency and reliability far exceeding their cost or complexity. For such a simple invention, the seal exists in countless configurations, often with nearly imperceptible differences, but different all the same. They seal shafts, spools, plates, pistons, rods and nearly every location with moving parts or between two locations of opposed pressure or fluid.

The two major classifications of seals are dynamic and static.

Dynamic seals must keep pressure contained as one surface slides across or rotates around another surface, such as rod seals, shaft seals and piston seals. They are most often cup-shaped to take advantage of pressure to increase sealing. Static seals, such as O-rings or gaskets, are used to separate two areas of a component, such as a reservoir lid or spool valve end covers.

Seal construction has come a long way, the majority of which is now of synthetic construction—Viton, Buna N or Teflon, to name a few. Seal composition needs to reflect the fluid used. Buna is fine for mineral oil, but Viton is required for exotic fluids such as glycols or esters. The shape of the seal is usually dictated by the location of its use. A piston seal typically has the cross-section appearance of a “U.” As you can imagine, pressure inside the middle of the U pushes the edges outward, with extra pressure creating extra sealing.

66

FLUID POWER WORLD

Seals_IFPE_Vs2 MG.indd 66

2 • 2017

The traditional O-ring is still very common; although less common these days in dynamic or high-pressure applications, it can still be found in countless applications, such as pump rear-covers or ISO valve mounting. Most high pressure O-ring applications used for static pressure holding require a back-up washer, typically made of Teflon, which prevents the O-ring from being extruded out the lower pressure side. Nearly every cartridge valve, for example, uses the O-ring/back-up washer configuration.

Seals are typically measured by their cross section width, their ID and their OD. Metric and SAE sizes are both common, and although component manufacturers offer rebuild kits with a complete set of seals (for cylinders, pumps, etc.), any competent technician can quickly measure up seals to be purchased through third-party sources.

How are hydraulic motors used on mobile machinery?

Im a Flu ge co iDy u ne rtesy Flu id P of ow e

r

Hydraulic motors are used in any application where the output of mechanical rotational energy is required, such as augers, wheel drives, fans, mixers, and grinders. Their execution is just as varied as their application, coming in motor types such as orbital, vane, gear and the major piston types—bent-axis, radial and axial.

Motors convert hydraulic energy into mechanical rotational energy. Their torque output is a factor of both motor displacement (the theoretical volume of fluid the motor requires to rotate one revolution) and operating pressure. Additionally, a hydraulic motor’s horsepower output is a factor of torque and speed (generally described in revolutions per minute, or rpm)

Each motor type excels in a few applications, but could function as a compromise in others. Orbital motors are the most polyonymous of the group, going by such monikers as low-speed/hightorque (LSHT), gerotor, geroller, and disc valve, to name a few. Mind you, the last three are actually different configurations of the same type of motor—however, their general function is the same, by using an off-set shaft inside-gear arrangement, with either a spool or disc valve.

Orbital motors are the least efficient type (although each motor type has a relatively efficient sweet spot in their pressure and speed curves), but excel at low-speed, high-torque applications, and are also very economical. They are found on the majority of farm-duty applications, such as conveyors or spreaders, and every application where price is the major consideration.

FLUID POWER WORLD

Hydraulic Motors_IFPE_Vs2 MG.indd 68

2 • 2017

Gear motors are very simple, using the same drive- and idle-gear layout as gear pumps, and although they are not any more efficient than orbital motors for the most part, they are inexpensive and work well at higher speeds. They are most often used when such a combination is required, such as cooling fan drives or pump drives.

Vane motors are the least common of the major types, but are respectable in their efficiency and speed output. They can also be had in large displacements, making them a good choice for high torque applications. They use a rotor with fixed vanes, just as vane pumps, although some manufacturers use a more complicated design with vanes on the housing as well. These motors can be seen in applications such as winches or drill rigs.

Piston motors are hard to beat in their output and efficiency. The bent-axis piston motor is the champion of high-speed operation, and can do so with huge amounts of pressure and torque. Their bent-axis design also makes them very reliable, able to handle 5,000-6,000 psi “’til the cows come home.” They’re used in any application where ultra-high speed and torque are required, such as grinders or vacuum pump drives. They’re not cheap, but they are unmatched in their power density.

The radial piston motor is the torque king of the hydraulic motor empire, not only available in gigantic displacements, but also extremely efficient in creating that torque. They’re not as fast as bent-axis motors, but are the top choice for wheel drives or other direct-drive high torque applications. It should be noted that while no piston-type motor can be called inexpensive, they at least provide unparalleled performance at any price.

How are filters used on mobile machinery?

A reliable and efficient hydraulic system starts with the fluid.

Keeping hydraulic oil conditioned and free of contaminants, air, water and heat is critical to ensuring that all system components run as they are meant to. To ensure this dependability, proper fluid filtration is required and should be taken with great care.

Contamination often enters a machine during startup, when particles from machine operations—be they metal shavings or sawdust or plastic bits—enter hoses, actuators, reservoirs and manifold ports.

These particles can also flood a system during maintenance, if proper preventions aren’t taken, or during a complete machine failure.

To prevent them from entering a system, use one of three main types of filters. The first, the suction filter, is mounted in the reservoir and attached to the suction line to protect downstream components, such as the pump. They are meant to catch coarse, large particles, so are not effective in trapping the major culprits of wear—fine particles.

These mesh steel filters are often not included in a system’s filtration design, as they can cause clogging and pump cavitation.

Next up is the pressure filter, which is installed in the pressure line, downstream of pumps and system circuits when fine filtration is required. This traps particles in fluid as it flows from the pump, so protects components downstream of the pump. You must select a pressure filter that matches the system pressure you’ll be operating in, but they are generally available in wide ranges up to and higher than 10,000 psi.

The most common type of filter is the return line filter, which traps very fine particles before the fluid reenters the reservoir. Spin-on filter and in-tank drop-in assemblies are the most popular. Spin-on filters are used heavily on mobile equipment. They are rated for most fluid types and a range of 70

Hydraulic Filters_IFPE_Vs2 MG.indd 70

FLUID POWER WORLD

pressures and temperatures. They are available in glass, cellulose fibers and paper media.

Water-absorbing medias also remove freestanding water from oil.

Growing in use in the mobile market are in-tank return filters. They use stronger filter media, such as synthetic and natural fibers and stainless steel wire mesh. Constructed of steel, aluminum or plastic, they suitable for heavyduty applications. And because they are located in the filter stream, they can remove most fine particles throughout the rest of the system, ensuring clean fluid enters the reservoir.

When selecting a filter you need to know what size particles it is rated to remove in one pass through. You must also know its efficiency or Beta ratio (the ratio of particles upstream of the filter to downstream of the filter during standardized testing). For example, we know how efficient a filter was at removing 10-micron particles in a single pass, such as 99%. In this case, “10 micron at Beta 200,” means the filter is 99.5% efficient at removing 10-micron particles in one pass. The lower the micron rating and higher the efficiency rating the better.

Other considerations include pressure drop, flow rate and size, and obviously, price. If sized improperly, filters can break, releasing all the collected contaminants back into the system. www.fluidpowerworld.com

How are pressure transducers used on mobile machinery?

The measurement of pressure had once been a monopoly of

Bourdon tube pressure gauges, and if you wanted to check the pressure at any location in a fluid power circuit, you had to go right to the source to install a pressure gauge at the location you wished to measure. The invention of test points and micro-bore hoses allowed for some distance between point of measure and point of reading, but reliable and accurate readings were still limited.

The proliferation of electronics into fluid power has changed the way we can measure pressure, and has enabled versatility not enjoyed previously. Pressure transducers are solid state, meaning there are no mechanical moving parts, instead using something called a strain gauge which changes in resistance when warped out of shape by pressure. Their solid-state nature means they are very reliable, often lasting millions of cycles.

Pressure transducers require a power source to give their output signal, usually a 24-V input. Their outputs are typically one of the standard control signals, such as 0-10 V or 4-20 mA, et al. This signal can be fed into a PLC for feedback of closed-loop control, such as servo-pump pressure control, or the transducer signal can simply plug into a digital display.

72

FLUID POWER WORLD

Pressure Transducers_IFPE_Vs2 MG.indd 72

2 • 2017

Transducers are typically male-threaded and plumbed into any location where you wish to measure pressure. When used in conjunction with a PLC, the basic plug-in type with a M12 or DIN connector is all that is needed. The transducer must be chosen for the appropriate pressure range it will measure, especially if you wish it to be accurate. For example, if you are measuring around 100 psi with a 0-10 V transducer, using a 1,000-psi transducer will only ever read 1 V, leaving the rest of the pressure range unused.

Pressure transducers are also available with on-board electronics, including displays and switches. One device, for example, can display the pressure, provide a handful of switch’s outputs with configurable switch-back points, and also provide its analog output for a PLC to use as well. With the cost of electronics at an all-time low, they’re not as expensive as you would think, either.

Crawler dozers are designed for tough mining, quarry, and construction operations. And like other equipment at these sites, the machines continue to get bigger as producers demand ever-increasing productivity at lower costs.

As such, Liebherr, with U.S. headquarters in Newport News, Va., recently unveiled the PR 776, its first offering of this type in the 70-ton category. Introduced into the American market late last year, it’s reportedly the world’s largest hydrostatically powered crawler tractor.

Infinitely variable drive

Competitive machines of this size typically rely on mechanical drives, such as a three-stage gear transmission with a torque converter and differential, explained Klaus Graner, Managing Director of Liebherr Components in Biberach, Germany. What sets the PR 776 apart is that, like all Liebherr crawler dozers, it instead uses an infinitely variable hydrostatic drive.

• The new PR 776 features a Liebherr 12-cylinder, 1,477 in.

(24.2 l) diesel engine developing 768 hp (565 kW), has a maximum operating weight of 74 tons and is equipped with blade capacities of up to 28.8 yd3 (22 m³).

• The PR 776, with a hydrostatic

drive, offers fuel savings of up to 20% versus similar crawler tractors with mechanical drives.

As a bit of background, a basic hydrostatic transmission consists of a hydraulic pump supplying high-pressure flow to a hydraulic motor which, in turn, propels a wheel or track drive. It includes all the necessary fluid conduits, connectors and controls. The systems are a proven means of power transmission that offer smooth and stepless adjustment of speed.

In concept, mechanical-gear transmissions are more efficient than hydrostatic transmissions. However, that assumes a vehicle operates within a relatively narrow range of required torque and speed.

Once the operator selects a gear ratio in a mechanical transmission, vehicle speed can only be changed by varying engine speed.

When the engine reaches maximum revs, the transmission must shift to a lower-ratio gear. The need to shift gears in mechanical designs interrupts power flow and traction, and it typically means large swings in engine speed, which wastes fuel, noted Graner.

“Normally, a gear box should offer good efficiency but, of course, the engine

is not always at the perfect point,” he said.

And to smooth the drive output, a torque converter is essential, but energy losses here can be sizeable as well, he added.

In contrast, the hydrostatic drive lets the operator continuously vary vehicle speed from creep to maximum with seamless and continuous power transmission to both tracks. That’s particularly advantageous when pushing a load under full power or climbing hills.

It’s also extremely efficient, said Graner.

Hydraulic servo pressure and flow are based on-demand. Electronic control of the system adjusts travel speed and drawbar pull to match load conditions. If full flow and pressure are not required, the load-sensing system automatically dials back hydraulic output and conserves energy. Likewise, in low power-demand situations the pump can increase output and let the dozer move at high speed without increasing engine speed.

Add to that, the hydrostatic transmission lets the PR 776 engine run at a lower speed—about 1,600 rpm—which further improves fuel efficiency, said Graner. Actual field data show fuel saving in the PR 776 of 15% to more than 20%, compared to competitive machines in this class performing similar tasks, he said.

Controllability

Another benefit to the user is simple and straightforward operation. For example, joystick movement signals the pumps to vary output and speed up or slow down the vehicle. Similar commands move the swash-

D R I VE S

plate over center and reverse flow to the motor, and let the vehicle change direction with simple fingertip control.

Maneuverability improves, too. The hydrostatic travel drive operates smoothly and automatically adjusts working speed to load conditions. Engine power always transmits to both tracks without interruption for fast and precise steering. This also minimizes track slip and lets operators concentrate on the work at hand.

It even offers pivot-turn capability. Powering one track in each direction (forward and back) lets the machine turn on the spot. This differs from other designs that power the outside track and brake the inner and require wider, more timeconsuming turns. “The maneuverability of this machine is by far superior to a torqueconverter drive,” said Graner.

The PR 776 has the added advantage of dynamic braking. Thanks to the self-locking nature of the hydrostatic drive, moving the joystick to neutral signals the pump to destroke and center the swashplate, which brings the machine to a halt. On slopes, the system ensures that the machine doesn’t

Matched components

The PR 776’s low fuel consumption and excellent controllability are due in large part to “perfect matching of components,” explained Graner. That includes not only those that make up the hydrostatic drive, but the electronic hardware, software and engine—and how they all interact.

For instance, thanks to common-rail fuel injection and optimized cylinder management and combustion, the latest generation of Liebherr diesel engines works efficiently at low speeds.

Drivetrain-system expertise, in turn, ensures the hydraulic pumps and motors are matched precisely to the diesel engine.

And critical to all this is the control logic and programming, said Graner. Sophisticated algorithms were developed that match hydrostatic-drivetrain performance characteristics

with engine output capabilities, as well as application considerations like operator demands and operating conditions.

The proprietary electronics and software combine in a modular platform that is scalable for small and large machines alike, and is used in other equipment like wheel loaders and excavators.

It’s also notable that the company not only designs and manufactures drivetrain components for its own machines, but also supplies them to many customers outside the Liebherr group.

The end result is that the system’s electronically controlled hydrostatic power and torque output deliver excellent traction and rapid response, while the “intelligent” engine-management system maintains constant engine speed and increases overall efficiency and performance of the PR 776.

fuel consumption compared with conventional machines handling similar tasks.

System details

The PR 776’s hydrostatic circuit includes several main components. A splitter box off the engine drives pumps for the travel drive (as well as for the work hydraulics). The closedcircuit system for each track requires two 280-cc DPVG swash-plate pumps supplying two 370-cc DMVA swash-plate hydraulic motors. Feed pumps and control and relief valves augment the circuit.

The variable-displacement, axial-piston pumps are rated for a maximum speed of 2,500 rpm and volumetric flow of 709 lpm. Nominal rated pressure is 450 bar and maximum pressure is 500 bar. The design includes a hydrostatic swash-plate cradle bearing, and the pumps are built for heavy-duty loads with high reliability and long service life, according to the company.

The variable, axial-piston motors have a nominal pressure rating of 400 bar and maximum pressure of 450 bar. Maximum speed at a ΔP of 430 bar is 2,400 rpm, and maximum rated flow is 888 lpm. Like the DPVG pump, it’s noted for high performance, ruggedness and efficiency.

Both pump and motor feature an inverted-piston design with a 22° swivel angle. The high swivel angle increases the conversion range and efficiency of the pumps and motors. Further, the compact rotary group and high-pressure capacity contribute to high power density. These pumps and motors are also used in related equipment like mining excavators and maritime cranes.

Robust and durable final drives on the PR 776, powered by the hydraulic motors, are designed to handle extreme loads typical of mining operations. The units combine spur and planetary gears, and include onboard temperature monitoring and double duo-cone transmission seals.

sions, the proven travel drive does not require more-problematic components such as a torque converter, multi-ratio transmission, service brakes or steering couplings. And by design, the hydrostatic system can be stalled without damage.

Liebherr hydraulic fluids permit service intervals as high as 8,000 hours of operation. These oils reduce friction, provide corrosion protection and offer excellent compatibility with hydraulic hoses, seals and gaskets. Thus, the fluids cut downtime, improve machine availability and, by minimizing resistance between moving parts, reduce fuel consumption.

Electronically controlled hydrostatic fans regulate hydraulicfluid and engine temperatures. Fan speed adjusts to operating requirements, which helps save fuel and minimize noise. An optional, reversible fan automatically cleans the radiator and coolers in dusty work environments.

In the past, dozers were viewed as rather difficult earthmoving machines to operate. The PR 776’s cab and operating platform helps ensure uncomplicated and safe operation. Not only do the ergonomic joysticks direct dynamic outputs like speed, steering and blade functions, adjustable settings let the operator tune the degree of control from delicate to aggressive, as needed.

The instruments and operating controls are organized for easy reach. For instance, the new PR 776 comes with an ECO function that lets the operator choose between maximum power for high performance and maximum efficiency in light-duty operations for greater fuel savings. Other settings like automatic engine-speed reduction, travel-drive response, and steering parameters as well as standard safety functions such as the rear-view camera can be all be accessed through the intuitive touchscreen display. All in all, the workspace is designed to minimize stress and strain on the operator and, in turn, improve overall performance and productivity.

Finally, the PR 776 comes with LiDAT, Liebherr’s vehicle and fleet data management system, which provides critical information on vehicle location, operation and health. For example, the system supplies information such as vehicle uptime, operating demands and fuel consumption. It also offers remote monitoring, tracks overloads and faults, initiates alarms, notes service intervals and facilitates proactive maintenance. Technicians can even log into the machine controls from any location and pinpoint faults and help correct malfunctions.

Last November, we delved into system-specific maintenance tips to ensure the hydraulics on your mobile machine runs at its highest performing levels. We continue this discussion with a look at more common components used in mobile hydraulics.

Using a scientific-based approach to understanding how long a component should operate reliably is critical to cost-effective operation of all hydraulic components. In part 1, we discussed the importance of keeping an eye on the following: 1 Fluid levels 2 Leaks and safety 3 Temperatures 4 Pressures Let’s look at seven more areas of fundamental care and maintenance your technicians should address.

5 Actuators and cycle times — Cylinder cycle time is key to productivity in a mine or on a highway construction site. Operators, not shop technicians, should time cycles with a stopwatch and keep track of data for all critical machine motions for both cylinders and motors on a regular basis. This is just good maintenance. As soon as a deviation occurs, the operator should involve the maintenance team, because it often means that some component behavior has changed or some internal leakage path may be occurring.

Equipment manufacturer service manuals usually lay out a host of tests for actuator speeds. Many fleet maintenance teams skip over these procedures because there are so many of them in the manuals, and the time, skill and instruments needed seem considerable. If an excavator is always used on level terrain and not on slopes, then some maintenance tests specified by the manufacturer for the travel function can be moved to longer intervals. But if that same excavator is always used to dig in very hard materials, then the Regularly timing and documenting the cycles for all machine motions enables system performance investigation to take place as early as possible.

relief valve setting and pump compensator setting checks should be performed at frequent intervals.

Volumetric testing of the main pumps to detect wear is a valuable maintenance task, but it’s not always easy. On some mobile machines it is difficult to install the test equipment. On some very large-scale machines, the flow rates are so high that appropriate flow meters are not easy to acquire. Keeping a close watch on all cylinder stroke times (at or near maximum load) and all hydraulic motor speeds can help determine when best to conduct those main pump tests. A slow actuator function can certainly be caused by problems other than pump wear. Keen system observation (component temperature, noises, etc.) can help with decision making for difficult maintenance tasks for large scale and complex machines.

Cylinders are the business end of most mobile machines. Decide in advance what depth of rod scratch and what rate of dripping from the rod gland will be considered a failed cylinder.

6 Fluid condition and cleanliness — Countless studies and papers clearly show how attention to the qualities and state of the hydraulic fluid is key to reliability and asset life, and how problems can be detected and dealt with at an early stage.

Fluid analysis was once only popular for aircraft and some large-scale utility plants. Today even the owner of a single piece of construction equipment can fit this cost into the maintenance budget. Many manufacturers now provide service ports to allow easy sample collection. The cost of fluid analysis at a laboratory is most often more than paid for by the unnecessary periodic filter changes that are avoided with careful monitoring.

The report can detect water leakage into the system, show that additive properties that help protect hydraulic components are breaking down, or that particle contaminants have reached levels that threaten pump life or valve reliability. Many training events are held annually and online resources can help to educate a machine owner or a technician on how to interpret oil analysis reports and get value from them.

Fluid sampling, analysis and the resultant decision-making done right offers payback in reliability and asset life.

7 Hoses — The outer wrap hydraulic hose is subjected to all temperature extremes, direct sunlight, rain and many other environmental effects. Add to this the flexing cycles and the moments of system overheating that may have occurred and hydraulic hose can be weakened even from the inside.

Outer wrap damage marks the end of hose life.

Hoses on mobile machines suffer abrasion damage more than any other wear effect.

It should be the operator’s job to keep a close watch for hose deterioration.

By the time a hose has been in place for several years on a steadily operating mobile machine, it is near the end of its predictable service life. For continuous operations such as waste disposal and recycling trucks in an urban center, or machines in a mine or on a construction site, careful tracking of historical records together with hours of service may provide optimal hose change frequencies. For small fleets or even single machines, it may be necessary to replace critical hoses in the high-pressure circuits every two to three years.

New electronic technology embedded into hydraulic hoses allows strain and deterioration to be easily detected via continuous measurement. Watch for this technology to become more affordable and help save on hose replacement costs and prevent many sudden failures and spills.

8 Pump and hydraulic motor mounting — A tiny amount of free play and misalignment on the mounting of a pump can bring on severe damage. A missing bolt or a number of loose bolts can result in catastrophic failure when pump shaft splines grind and twist in the socket of the driving gear. Check pump mount bolts at the drive box or PTO for correct torque value. A simple visual observation that the bolts are not loose is not good enough. Similar issues apply for the hydraulic motor mounts.

9 Overall mechanical lubrication — Obviously a mobile machine has more systems to maintain than just the hydraulics.

Gearbox lube and the greasing of swing gears and bearings, along with the pins where the cylinders mount and pivot can directly impact hydraulic system performance. Failing to grease can show up as a hydraulic cylinder slowdown or stall, and possibly an overtemperature condition as well. If enough mechanical binding occurs, pressures may reach maximum values with minimum payloads on a lifting boom and a relief valve may crack open, dividing flow.

10 Brakes — Brake systems need to be reliable to the maximum degree. Many off-highway mobile machines such as loaders and graders utilize the main hydraulic system for braking functions. Often these machines are in transit on public highways. Whether they are on road or off, braking action is crucial to human safety.

Most hydraulic brake systems consist of a gear or piston pump that flows through a check valve as it charges a small accumulator to a specific pressure. Once the correct pressure is reached, the brake pump is unloaded through a special valve. Obviously the accumulator precharge gas pressure will need to be checked periodically.

Keep in mind that the braking circuit is not really a flow-based motion control circuit. It is a force control circuit. As the operator slightly depresses the brake pedal, (a valve most similar to a pressure reducing valve), the spool opens for only for a brief moment.

Contaminants in the fluid could easily cause such a valve to stick open, which would apply full braking force, or prevent the system check valve at the beginning of the circuit from closing. Any air in the system will cause a delayed, weak and spongy brake response (another very important reason to keep the reservoir topped up at the correct level). For the sake of human safety, the quality of hydraulic fluid must be maintained to the highest level.

11 Steering — Like the braking system, the reliability of hydraulic steering is key to human safety. Also similar to the braking system, an accumulator may be involved. It will likely be larger than the brake accumulator because unlike the braking system, steering is a flow-based motion control system.

Steering in some machine designs has done away with the steering wheel and orbitrol valve in favor of the joystick. Operator strain and fatigue is minimized, but again, electronics, fine proportional valves and pilot systems may be present, minimizing contamination tolerance.

Conclusion The categories and tasks above are by no means exhaustive. There are types of mobile machines and hydraulic components that didn’t get any mention. The idea here is to envision, describe and document the ideal state of care for your mobile machine’s hydraulic system, and then build up a program of relevant maintenance tasks. Your business goals should ultimately drive the maintenance program, and in so doing, make it easy to eliminate any historical 86

maintenance checks and tasks that merely consume time or that receive a check mark from a distance.

The more challenging part of designing or refining the maintenance program is to learn all about the hydraulic system that you have. Learn exactly how all circuits and components are configured and how they function. Finding out perhaps that your electronic operated steering valve has a required particle count level similar to the cleanliness required of a helicopter hydraulic servovalve can be the impetus behind much stricter fluid management and maintenance.

Finding out that cool weather may be causing your higher viscosity hydraulic fluid to bypass the filters during startup can drive maintenance decisions.

Discovering that broken pump shafts have occurred at engine startup due to

incorrect pressure valve adjustment is an expensive education, but one that can bring emphasis to designing useful and valuable maintenance tasks.

With training and the pursuit of continuous learning may come the need to purchase and maintain a set of predictive maintenance tools, such as the thermography camera and the non-contact tachometer mentioned in part 1 of this series. Flow meters and diagnostic pressure gauges with a complete set of adapters and fittings become key tools for those who truly wish to know the state of the hydraulic system.

Many small shops and even some fleet maintenance departments do not have these tools. The reason for avoiding their purchase is often tied to the fact that there are no technicians on-site who are trained to use them, or because none of the periodic maintenance tasks found on those

long lists also mentioned, require their use.

Assuming that you have purchased a well-designed piece of mobile equipment and are using it within its intended scope of capabilities, the hydraulic system could in theory, last and even function trouble free for at least two decades. Keeping the oil very clean and topped up, temperatures under control, worn hoses replaced, fasteners and fittings checked for torque, pressure valves properly adjusted, with pump flow tests conducted at least annually are the maintenance tasks most likely to achieve 80% of the result. The remaining 20% will come from very careful observation of machinery performance, from vigilance and from continual learning.

Staying dry

with cool air

Researching types of refrigerated compressed air dryers and understanding your application is necessary when looking for a long-lived, efficient and cost-effective system.

Ron Marshall

Contributing Editor

When you are in the market for a refrigerated compressed air dryer, it is wise to do some research to find the most economical choice. Air dryers last for many years and can consume a significant amount of energy through the life of the equipment. Choosing a low cost unit that consumes more power can end up costing more in the long run.

Non-cycling versus cycling

Refrigerated dryers, as the name implies, use a refrigerating circuit to cool the compressed air to remove moisture. This produces compressed air with dew points of about 2° C (35° F). The two basic types of refrigerated dryers are cycling and non-cycling.

Non-cycling dryers use a type of control that maintains the internal dryer temperatures to provide cooling and drying action but does not act to achieve very much of an energy turn-down through the full range of the air 88

dryer loading. Basically, this type of dryer consumes almost the same energy whether or not there is full flow or low flow. If this dryer is used on systems that run at partial loads, some significant amount of energy is wasted.

Cycling dryers, on the other hand, cycle the refrigeration on or off like your refrigerator at home, and in doing so have an energy turn-down that is directly related to the dryer moisture loading. If the dryer is lightly loaded, its energy consumption will be reduced depending on the energy turn down characteristics of the dryer.

Many manufacturers are members of the Compressed Air and Gas Institute and, as such, must publish CAGI data sheets for a certain size range of air dryers. You can use the sheets to figure out the energy savings of one dryer compared to another.

For example, a 1,000 cfm non cycling dryer might consume 7.3 kW at an average loading of 40%, costing about $6,400 per year to operate at 10 cents per kWh.

A similar sized cycling dryer might consume about 4.2 kW under the same loading, costing only about $3,680 per year. Over a 15-year dryer life, this difference might total $41,000 in electricity costs. This should be compared with the purchase price for the two units to make a wise comparison.

Consider load and pressure differential

Of course, if your dryer always runs at full load, then the calculations would be different and might even show the cycling dryer would consume more power, so loading conditions should always be taken into account.

Another thing you should look at is the dryer pressure differential. The range of makes and models may have different pressure drops—this can affect the operation of the air compressors. A dryer with a 5-psid pressure differential may cause the compressors to consume more energy due to more frequent compressor cycles and higher discharge pressures, which makes the air compressors consume more energy.

pressor. If you want your air to be dried to proper specifications under all conditions, then some research is required that may require you to adjust to a larger size.

Air dryer ratings are affected by various factors, the most important of which are the inlet air pressure, the temperature of the inlet air, and the temperature of the ambient air in which the unit must operate. If these are beyond the dryer design specifications, then some sizing adjustment is required.

In North America, the typical dryer specifications follow the “three 100” rule— that is, the dryer is designed to adequately condition the air to rated dew point with 100 psi inlet air pressure, 100° F inlet air temperature, and 100° F ambient. In other countries there are different ratings, especially in tropical environments.

FX range of refrigerant dryers from Atlas Copco removes condensation and opportunities for corrosion and damage by removing water from the air.

Operating the dryer at lower than rated pressure causes higher than normal air velocities inside the dryer, making it harder to remove the moisture. Higher than rated inlet air temperatures introduce more moisture loading to the dryer, because for every 20° F increase in air temperature, the amount of water vapor roughly doubles, making the refrigerant circuit work

harder or loading the desiccant more.

And because the moisture inside the dryer releases heat when it condenses, the heat exchanger circuit inside the air dryer (refrigerant types) needs adequate ambient air (or water) temperatures to remove the heat.

A typical worst-case scenario might be during the hottest, most humid day, when the compressors are fully loaded during a system peak. To prevent moisture from overwhelming the dryer, its capacity must be adequate to compensate for any excessive operating conditions.

Most dryer manufacturers have sizing tables in their sales literature—be sure to carefully examine these and run the proper correction of your dryer size to prevent future water contamination problems.

For example, suppose your air dryer is in a hot compressor room and must operate with an air cooled compressor that produces 500 cfm of 120° F compressed air at 90 psi in summer and that the ambient conditions near the dryer are 110° F. If you wanted a properly sized dryer from one example supplier, you should add 51% for the high inlet temperature, about 5% for the lower pressure and another 16% for high ambient temperatures.

This would result in a dryer rated at about 500 x 1.51 x 1.05 x 1.16 = 920 cfm.

You may ask, if the inlet air temperature is cool, my pressure is high, and ambient conditions are much lower than specifications, can I reduce the size of the dryer? Well, the answer is yes, but this causes another problem: pressure differential. Passing more than rated air flow through a dryer causes significantly higher pressure differential than rated to

Conclusion

Proper dryer selection should be based on a number of factors. First, understand your application and whether your load will be full or only partial throughout the dryer’s use. Only then should sizing come into play. Compressed air can be an expensive utility if not sized and maintained properly. Careful research and selection is critical in keeping your refrigerated compressed air dryers running efficiently over their expected life cycles.

Various types of contamination can occur in fluid power systems: gaseous (e.g. air), liquid (e.g. water) and solid contaminants. Water should be considered a contaminant and it is important not to overlook it. Water ingress can be caused by moisture from ambient air, leakage of seals and chemical processes such as combustion, oxidation and neutralization.

“Water can be present in a dissolved state and a free state (when the saturation point of the fluid has been surpassed),” said Dan Zoller, Group Product Manager Filter Systems for Schroeder Industries. “Either form of water is harmful to both the fluid and the hydraulic system itself. Free water needs to be avoided and removed if present. The level of dissolved water needs to be kept as low as possible. Always follow fluid supplier guidelines to avoid cooler fluid, e.g. in the reservoir, to shed free water due to the lower ability to hold dissolved water at lower fluid temperature.”

In order to remove water, different methods are available. “However, there are both advantages and disadvantages to all methods that must be considered,” Zoller said.

Vacuum dehydrators

In vacuum-based systems, a vacuum is created in a vacuum chamber by means of a vacuum pump.

With the vacuum, ambient air is sucked into the vacuum chamber. The vacuum expands the ambient air and proportionately reduces the relative humidity of the air. The oil is distributing within the vacuum chamber over a large surface area, resulting in a large and thin fluid film.

“Due to the temperature increase when coming into contact with the warmer oil, the air is further dried and takes up the water from the oil,” Zoller said. “The humid air is evacuated via the vacuum pump. Depending on the applied vacuum and oil temperature, the water is evaporated (mass transfer) or boiled out (flash distillation) from the oil.”

Water absorbing elements Super absorbent polymer (SAP)

Conversion from free water to high viscosity gel is done via cross-linked polymer particles with integrated sodium ions.

Osmotic pressure sucks ambient water into the polymer particles.

“Water absorption is limited by elastic memory forces of the polymer particles,” Zoller said. “The absorbed water cannot be taken out again by increasing pressure. The super absorber is not soluble in mineral oils and synthetic esters applications. A layered structure of the element prevents transfer of the polymer to the hydraulic system.”

Coalescing elements

“Free water settles on the fibers of the coalescing element,” Zoller said.

“Droplets are transported deeper into the coalescing element by the fluid flow. Smaller drops unite to form larger ones at the fiber nodes during this process. Large water droplets are separated by gravity or with a special separation element/layer. Water is collected on the bottom of the housing (for phosphate esters on top) and it can be discharged by opening a valve.”

Advantage: High dewatering rates for high water contents (free water), suitable for hydraulic- and lubricating oils and diesel fuels, removes also particles in one element, high flow rates possible up to 2,000 gpm for diesel.

Disadvantage: Only free and emulsified water removal, no gas removal

(degassing).

Gravity separation

Zoller said that because water generally has a higher specific gravity than hydraulic fluid, it tends to settle at the bottom of the reservoir when given sufficient resident time in a still environment. “In basic systems, opening the drain valve and allowing the water to drain off may be sufficient. Increasing the fluid’s temperature and employing a cone-shaped separating tank improve the effectiveness of gravity separation,” he said.

Advantage: Simple device, low cost of water removal.

Disadvantage: Only free water is removed, high fluid viscosity /oxidation by-products and polar additives and impurities inhibit the effective separation of oil and water, some oils are designed to hold water in suspension rather than to allow it to separate out, takes time, need of usually two tanks and therefore double the space and oil, no gas removal (degassing).

“By spinning the fluid, the difference in specific gravity between the fluid and the water is magnified. Centrifugal separators remove free water faster than gravity separators. They also remove some emulsified water depending upon the relative strength of the emulsion vs. the centrifugal force of the separator. They are a good option for continuous decontamination of fluids with good demulsibility (water separating characteristics), Zoller said.

Advantage: High dewatering rates for high water contents (free water), removes larger particles due to gravity.

Positive pressure dehydrators

Notes:

“Positive pressure systems blow air through the operating fluid in a reaction chamber,” said Zoller. “Drying the air is achieved by increasing the temperature of the ambient air in a side channel blower and by getting it into contact with warmer oil. The air is introduced into the reaction chamber by a blower. The dry air takes up the water from the oil and is pushed out of the reaction chamber by the incoming air.

The operating fluid is cycled through the reaction chamber by a system of two pumps.”

*1: Absorbing Elements do have a micron rating as well that is relatively high for certain manufacturers (e.g. 40 microns), but the main purpose is for water removal. Ideally, absorbing elements should be used in conjunction with particulate elements (staged filtration)

Advantage: Higher dewatering rates for free water

compared to vacuum purifiers due to higher air flow rates, removes free and dissolved water, no expensive vacuum pump to service or replace.

Disadvantage: Less effective at high ambient humidity, less effective at high water contents compared to centrifugal or coalescing systems, no gas removal (degassing).

When should you use offline filtration?

Hand-held portable filters, OF7 like this OF7 series, are used for transfering and filtering oils, and can remove water from oil, flush small hydraulic systems, and provide offline filtration of hydraulic systems with inadequate filtering capacity.

Sometimes, inline hydraulic filters are not enough to keep a hydraulic system happy. Most hydraulic systems are installed with at least a return filter, which semipurifies fluid before it is once again welcomed into the reservoir. However, what if a single return filter is not enough? What if your cleanliness codes are not achieved, even if you’ve upgraded to a finer filter media? A pressure filter is an option, which will keep the components downstream of the element one step cleaner. But what if using a pressure filter is impossible, due to plumbing difficulties or pressure drop considerations?

COMPONENT FOCUS

There is more than one way to skin the proverbial cat, and a solid option to increase filtration effectiveness is with an offline filter system, often called kidney loop filters. Offline filtration uses a dedicated lower pressure pump (still often a hydraulic pump), which draws fluid from the reservoir and then flows that fluid through a dedicated filter assembly— usually of a very high quality medium—and then right back into the tank.

Sometimes hydraulic power units have dedicated offline filter systems, whose only jobs are to circulate fluid from their reservoirs and filter it as it does so. Because a kidney loop filter neither affects nor is affected by the main hydraulic system, it is a consistent and stable way to keep the oil clean. The pressure drop of often lowmicron filter media will never be additive to system pressure drop, especially those related to flow surges in the tank lines of machines with rapid cycle times of cylinders. It is not uncommon to see 5- or even 3-micron offline filters with very high beta ratios.

Offline filtration also enables easy changing of filter elements while the machine is running, as shutting down the kidney loop has no association with machine operation. Some filtration systems employ duplex filters, which are two filter assemblies installed in parallel, separated by a three-way ball-valve, allowing live selection of either filter so the other can be replaced. Most filter manufacturers offer a filter system dedicated to the offline filtration market. These are highly efficient and offer high dirt holding capacity.

Offline filtration is typically the highest quality in a manufacturer’s product line, which is reflected in the cost of these products. To help justify the purchase of such a system, they are often sold as portable units; small units that can be carried by a handle or large units requiring a wheeled cart to manage their bulk. These units can be wheeled from machine to

machine, where a suction tube is placed into a port of the reservoir and then passes through its own filters before being injected back into the tank.

Depending on the size of the tank, the filter system’s flow rate and filter quality, one might leave the filter system running on the machine for hours or perhaps days.

Some of these filter systems are installed with auxiliary electronics, such as particle counters. A particle counter will give you a live reading of the ISO Code of the oil passing through the unit, so you can leave the unit running until the desired code is achieved. If this type of system seems out of your reach as a small end-user, the good news is most hydraulic distributors rent these machines at a fair rate, so even the little guy now has no excuse for dirty oil.
