Why so

Serious?

I was looking at famous movie lines one

evening and thinking about how they might relate to business.

The movie line that caught my eye is from The Dark Knight: “Why so serious?”

Do you feel we have become a society so serious it is impossible to generate any enthusiasm? Do you take yourself too seriously? Does your company? Most of the companies in our industry have enjoyed success over the last two years. Does it feel that way? I don’t think so.

Everyone is concerned about the next recession. We need to remember that many of our younger associates have never been involved in a recession the likes of 2009. They may think all recessions are as severe as the one we’ve just experienced.

It is time to help them understand the facts. Many of the companies in our industry have had substantial earnings growth, and more money is being allocated to research and development and plant modernization. The question you David E. Thun might want to ask is if the money you are putting into develPower Systems opment and plant modernization is being used to bring forth new products. Are we wasting some of our R&D money?

Do we have enough new products in the pipeline to protect our future?

The fluid power industry has always moved forward with new ideas, so we can’t let our products turn into commodities by lack of development. We know how much fun it is to sell the latest new “thingamabob,” but it is even more enjoyable to show a customer a new product and see his or her face light up.

We need to generate more enthusiasm and trust in our associates. Remove the fear factor.

There are fewer associates doing more work. In fact, labor cost on products has dropped 3.5% since 2008 according to statistics provided by the U.S. government. Associates like to have fun. It makes them feel like part of the team and more creative, so do some things out of the ordinary. Take them golfing, to a baseball game, maybe a picnic in the park, walk around with bare feet, buy everyone hamburgers for lunch and have the local ice cream truck stop by with treats. Associates like surprises. They may think you are weird, but weird is good. I guarantee they will remember and respect you.

We have some of the most creative people in the world in this industry, and we need all of them for our future. If you create enthusiasm and trust, products and ideas will flow. We are becoming more competitive in the world market every day. Let’s strike while we have the opportunity. We have the rest of the world on the run because of our technology, logistics, and speed to market. Are you ready to create this new environment for future growth and profits, and most of all have a little fun?

WHY SO SERIOUS?

Saving energy and money with fluid power…

F

luid power (hydraulics and pneumatics) is used in dozens of industries and hundreds of applications to precisely control the movement of machinery and material. Yet many engineers and technicians working in those industries do not fully understand the design concepts critical to developing efficient fluid power systems and the diagnostic and maintenance techniques essential to keep those systems operating at peak efficiency. These concepts and techniques can result in significant energy and cost savings for companies that use hydraulics or pneumatics, as well as for the customers they serve, making fluid power a more competitive technology choice.

To help companies take advantage of these opportunities, three leading fluid power organizations— the International Fluid Power Society, the FPDA Motion and Control Network, and the National Fluid Power Association—will be hosting an educa-

New Problem: Hydraulic Cylinder Requirements A 2-inch hydraulic cylinder is required to move a 1000-lb load vertically upward. Please calculate: a. The steady–state force required to move the load at 20-ft/sec. b. The total force required to accelerate the load from a stationary position to 20-ft/sec in 1-seconds. c. The pressures required for steady-state motion and acceleration.

Please ignore friction losses. The steady-state force (F ss) required to move the load vertically at 20-ft/sec or at any constant velocity (speed) is equal to the weight of the load. F ss = 1000lbs

Previous Problem: Single Acting Pneumatic Cylinder (From July/August 2011 Issue) Illustration: John Spisak

A single–acting cylinder with a 2.5-inch diameter piston and 12-inch stroke operates at 100 psig and reciprocates at 30 cycles per minute. Please compute the air consumption in scfm.

Solution:

Q1 = Q2 (P2/P1) (T1/ T2) = Q2 = (4.908-in2 x 12-in -30-cycles/ 1728) = Therefore Q1 = P2 x Q2 / P1 = 114.7 x 1.02 / 14.7 = Q1 = 7.96-Scfm

CORRECTION: Please note the following correction to the "Heat Transfer Rate" answer in the July/August issue.

H.P. radiated = vertical oil surface area x temperature change / 1000, HP heat radiated = 2545-BTU’s/hour or 42.4-Btu’s/minute. The bottom of the reservoir area is not considered due to the fact that heat rises.

Therefore, the question stated a hydraulic reservoir is mounted so the air will circulate freely around the reservoir with the following measurements: • Hydraulic fluid is 1.5-ft. deep in the reservoir 1-ft by 2-ft • Hydraulic system temperature is 130ºF • Air temperature is 70ºF. Please remember: you need to determine the reservoir surface area that is contacting the hydraulic oil.

Solution:

Area: = 2-ft x 1.5-ft x 2-walls = 6-ft2 Then calculating the area of the end walls: Area: = 1-ft x 1.5 x 2-ft = 3-ft2 Therefore: the total contact area would equal 9-ft2 Temperature difference is 130ºF minus 70ºF = 60ºF Q = Sq.Ft. x delta-T / 1000 = HP loss

Circle 157 8

september/october 2011

Q= 9-ft2 x 60ºF / 1000 = 540 / 1000 = 0.54 x 2545-BTU’s/ hr = 1374.3-Btu’s/hour is the correct answer.

Mechanical Valve Interlocks Netherlocks The company’s mechanical valve interlocks are operated with two color-coded keys that control, through a trapped key mechanism, the open and closed position of a valve, and communicate its current state. When the green key is released, the valve is locked in the “locked-open” position. For the red key to be released, the valve must be locked in the “locked-closed” position. If a valve is left in a midway position between open and closed, both keys are trapped in the device. Through this system, the current position of the valve is guaranteed. They are fully mechanical with no need for electronic wiring. The interlocks can be easily incorporated into new construction and are suitable for retrofitting older installations to mitigate potential safety issues. www.netherlocks.com

HANDLING LARGE LOADS

Part two

In

larger-load handling, the consequence of dropping the part is that much more expensive and of course more dangerous than handling small parts inside a guarded machine area.

This article focuses on the solutions that should be employed to prevent the dropping of a load due to power failure, be it compressed air or electrical.

When vacuum lifting, it’s easy to select a simple vacuum generator and cup.

However, if compressed air or electrical power is suddenly lost, the load will fall unless safety logic is employed in the system. There are some products available that offer an all-encompassing logic circuit, but these are expensive and very limited in respect to the potential vacuum flow they can offer. This article will explain the individual components that should be employed in preventing sudden vacuum grip loss.

Fig. 1 shows a typical all-pneumatic vacuum circuit that includes multiple vacuum circuits and safety shut-off valves. The order of operation is as follows: The compressed air MAIN SUPPLY connects to the vacuum generator, which in turn evacuates the vacuum tank after pulling the check valve open. The piping between the tank and the P ports of the control valves (C1 and C2) is also evacuated to the maximum vacuum level of the vacuum generator. If this vacuum generator has an “energy saving circuit” (which is recommended in most cases), the generator will turn OFF when the vacuum level is reached. The vacuum remains in the circuit, as the check valve closes when the generator is turned off.

When the vacuum cups are placed against the product to be lifted, the pneumatic pilot control valves (Fig. 2) are powered by the control supply circuit. The safety valves (S1 and S2), which are normally closed (NC), are

12

september/october 2011

By Daniel Pascoe

powered OPEN by the Mains Supply, allowing vacuum to reach the cup face. The part is lifted by the machine. When the pilot signal is removed from C1 and C2, the part is released.

The safety valves will always be open if a mains compressed air supply is present.

During a lift cycle, if the mains supply air is lost, the safety valves S1 and S2 will close, maintaining vacuum to the cups. The length of time the cups retain a holding force on the part is determined by the porosity of the product being handled and the leak tight condition of the system (interconnecting fittings and hose).

Fig. 3 shows a typical electrical pump circuit. Identical in operation to the pneumatic circuit shown in Fig. 1, this system uses solenoid valves (Fig. 4) instead of pneumatically piloted valves. Therefore, if mains power is lost to the vacuum pump, the safety valves S1 and S2 will close maintaining vacuum to the cups.

Vacuum tanks or reservoirs are very useful and a low-cost option for added safety in a vacuum circuit. These are employed in both the pneumatic and electrical circuits shown in Fig. 1 and Fig. 3. The tank offers a buffer in the vacuum circuit to compensate for leakage in the circuit, therefore reducing potential vacuum decay rate but also offering the benefit of instant vacuum power being available when the vacuum controls valves are employed.

Assume, for ease of calculation, your vacuum circuit has a piping volume of 1 liter between the control valves and the cup face(s), and the volume, including tank and piping, between the tank and the valve is 10 liters. If the system vacuum level at rest is 24"Hg when the control valves are opened, the whole pilot circuit, which is now 11 liters, will equalize. Thereport fore, the system vacuum level only drops to 21.8"Hg and then immediately starts increasing as the pump or generator returns the system to final vacuum level.

(Calculation explained: 10/11= 0.91. 24"Hg x 0.91 = 21.8). Cycle times will be greatly increased as the Fig. 2 system does not have to “ramp up” (start again) each time the control valves are powered. www.fluidpowerjournal.com | www.ifps.org

Vacuum filtration is not shown in Fig. 1 or Fig. 2, however, vacuum filters should always be used to protect the pump or generator from debris on the parts being handled. That being said, the selection of filtration models and most importantly where they are placed in a vacuum circuit will determine the safety of the complete lifting application. Some manufacturers offer filter pads or disks that are installed inside the vacuum cup. These are very rarely a good idea. The simple reason is that unless they are checked very regularly, the user is unaware of how much these filters are restricting vacuum flow and indeed the lifting force of the associated cup. It is also very hard to know if the filters are clogged. The vacuum reading taken from the circuit via either a gauge or transducer could be much higher than what the actual cups are experiencing.

A single point filter should be used that is easily cleaned and inspected, and more importantly, offers a longer element life compared with filter disks installed inside cups.

Fig. 4

As discussed in Part One of this article, when selfclosing valves are employed on each vacuum cup, if one of the cups breaks away from the load or does not seal properly, the cup is isolated from the rest of the circuit, and the holding capacity of the remaining cups is not affected. Each vacuum cup in the circuits shown should have one of these valves installed.

By using two interlaced vacuum circuits, self-closing valves (velocity fuses), safety shut-off valves, vacuum tanks, and single point filtration, the user is assured of a safe, yet simple, large-load vacuum-lifting system.

LEAKS ARE THERE FOR FINDING

T

he continual buzz about leaks in compressed air systems has jaded many. Whether a popular topic or not, the challenge to fix leaks persists and like mowing the grass, it should be done at regular intervals. This could be a good project for a summer student with regular follow up the rest of the year. Introducing students to the wonders of manufacturing and maintenance might save bright young minds from wasting themselves as bankers or lawyers. Some might wonder why leaks cannot be fixed once and for all by just tightening and sealing fittings and joints.

The functional leak paths, like relief and exhaust ports, will deteriorate as the products wear. These leaks don’t exist until the seals wear sufficiently at random intervals. A casual trip around the area with a sonic ear may detect a few leaky joints. Iridescent dye added to lubricating oil highlights leaky fittings and joints that are easy to find with a special blue light.

This method also tends to show the more visible leaks and misses those in the belly of the beast. By looking at the dynamic devices of all sizes, shapes, and capacity, visible and obscured, many more leaks may be found. The following are a few examples of existing or potential leaks that may go undetected unless sought out. These examples are not nearly a complete list but may help you think more about leaks.

1. The filter (Fig. 1) has fittings, a bowl seal, and automatic or manual drain. The filter element should be replaced and the drain examined annually to prevent pressure drop. A repair kit with fresh replacement parts, seals, and filter element could be installed with care to prevent leaks.

2. Regulators (Fig. 2) often have a main valve and relief path seals. If either of these or both become badly worn, compressed air will escape.

3. Valves (Fig. 3) may develop leaks past the spool or poppet, and vent through exhaust ports including the solenoid exhaust.

4. Cylinders (Fig. 4) often develop leaks through the rod gland that may be audible or recognized by escaping lubricant smear. Leaks past the piston seal may feed back and exit through the valve. Air exhausting from the valve even when the valve has been repaired or replaced may be confusing.

It would be good to hear feedback on pneumatic plumbing innovations. Any contribution to fewer leaks, less rust and corrosion, and less pressure drop sounds like an idea whose time has come.

The LubeEngineers’Forum

Engineered Solutions, Systems Integration

By Wade Parks, Owner – WP Associates

If we accept that over-lubrication is just as bad as under-lubrication, it would follow that knowing how to arrive at the proper lubrication requirements would be obligatory.

If this statement is agreed with, it would follow that a regular training program must be in place and operative.

If there is no budget money available for training seminars, the training must be obtained elsewhere.

Under-lubrication problems include: 1) inadequate grease film surface, 2) heat and contaminate damage, 3) premature failure, and 4) unscheduled downtime.

Over-lubrication problems include: 1) wasted lubricant, 2) caked grease that moves away from a bearing inner race and provides zero lube, and 3) spillage that creates a safety hazard and housekeeping issues.

Application Example Are you considering a new circulating or terminating lube oil, or grease system? Here are a few things not to do.

Don’t

make the reservoir any less in capacity than five times the pump flow in GPM, unless you have the cooling capacity of reducing the returning oil flow temperature by 60°F. If necessary, add a supplemental reservoir at the same elevation as the original tank, and connect them with (2) six-inch pipes. Install baffles with cutouts to cause flow to enter one tank and be suctioned back into system from the second tank. This arrangement will likely accommodate a new cooling and filtration pumping system, which will move oil in a circular motion through both tanks offering cleaning for both.

Don’t create excess friction HP losses, turbulence, and heat by under-sizing piping.

Pipe Size and Velocity Reference used at WP Associates: • 2 FPS calls for 0.8 square inches pipe area per each 5 GPM flow.

• 10 FPS calls for 0.1604 square inches area per each 5 GPM • 15 FPS calls for 0.1069 square inches per each 5 GPM Don’t install gravity feed return piping at any less than 3% slope back to tank at maximum 2 FPS. Eliminate all pipe ells possible.

Don’t install any circulating system without adequate cooling and filtration.

An ISO cleanliness level of 14/12 or better is recommended. Filtration may be kept efficiently installed, as well as preventive of bearing or gear failure using a 15-micron pre-filter along with a 3-micron coalescing final filter.

The oil moisture level in Parts Per Million (PPM) must be kept at or below one PPM for premature failure to be avoided. We consider that the result of water accelerated fatigue in bearing lifetime to be a reduction by 48% at a water content level of 0.02% (2 PPM). Coalescing filters are adequate when system water ingress is very small, but vacuum dehydration or distillation is required for water at a level of 1 PPM and above.

Oil temperature returning to tank will have increasing, cumulative Delta T. Oil cooling method of preference is oil to water heat transfer. Cooler should be sized for max available temperature cooling water into cooler, and given the proper flow to remove heat gain expected from bearing generated heat, ambient temperature, and friction losses.

Don’t forget sensor/transmitters for tank level and temperature plus delivery pressure and flow to lube points.

There should be tank level switches with transmitters communicating with operations, including a low level when tank is at 50% full and a low-low level switch to advise when tank is at 25% fill. Based on knowing pump flow versus remaining storage, a decision may be made as to shutting down the machine.

Temperature sensor/transmitters can warn of an over-heating bearing or machine, warn you of a

blocked or leaking cooling water supply, and can isolate problems within a system using remote sensing in a PID loop. Flow transmitters located throughout the system can advise you of line leak, with location. Pressure transmitters may also used to isolate leaks, and may also warn of impending pump failure.

Don’t forget that in circulating systems, the bearing housing outlets must also be sized to permit free flow into return piping to eliminate backup in the housing, resulting in shaft seal overpressure and failure.

For a complete listing of things to do, submit your system requirements including: • Bearing OD and width with number of rows, and whether ball, roller, or plain • Number of bearings to be lubricated, with existing max running temperature • Max and Min ambient temperature, indoor/ outdoor • Water or air to be used for cooling with max temperature of medium selected • Distance and elevation change between pump and bearings • Number of directional changes in both supply and return piping For a terminating oil system, eliminate cooling system.

The LubeEngineers’Forum

Exact Lubrication The design of circulating or terminating oil or grease systems is typically done using established formula for determining dosage amount and frequency, based on known data such as bearing width and OD and other surface area considerations like number of rows.

• For circulating oil systems we use bearing flow in GPM = OD x width, divided by 144.

• For grease we use width x OD divided by 12.2 = ounces/week.

System demands for heat transfer and particulate flushing must also be considered.

For terminating oil or grease systems, we deter-

mine the amount of lubricant that will replenish the suggested film thickness requirement.

Lubricant capacity may be determined by multiplying surface area by desired film thickness, for suggested film thickness capacity per hour, per the following: • Circulating Oil Systems: 0.060" film thickness per hour for each square inch surface area • Terminating Oil Systems: 0.001" film thickness per hour for each square inch surface area • Terminating Grease Systems: 0.00025" film thickness per hour for each square inch area.

Example: Circulating Oil System One hundred twenty (120) single row roller bearings with 2" shaft diameter. Use 2.0 (shaft diameter) squared x .060 (film thickness per hour) x 120 bearings = 2.0 x 2.0 x .060 x 120 = 28.8 cubic inches per hour system total. System PC could be set to deliver 7.2 cubic inches every 15 minutes for best practice application through series of metering valves of proper dosage to each individual bearing.

Lubricant selection and management is a vital factor for application success, and preventive maintenance is equally vital. A good maintenance program is essential.

In the quest for improved fuel consumption, the manufacturer of an engine-powered, mobile hydraulic machine replaced the fixed-displacement pump powering the machine’s attachment with a variable-displacement unit.

The ground drive on the machine already featured a variable-displacement piston-pump (hydrostatic transmission), and so upgrading the attachment’s hydraulic circuit to a more efficient configuration was considered logical progression by the machine’s design engineers.

When this modification was tested, the engineers were shocked to find that fuel consumption had actually increased by 12% to 15%! Upon analysis, the hike in fuel consumption was attributed to an increase in oil viscosity brought about by a 30°C drop in operating oil temperature. In other words, the “thicker” oil had resulted in extra drag on the hydrostatic transmission powering the ground-drive, causing the machine to use more fuel.

The machine employed a two-section, combination heat-exchanger for both hydraulic oil and engine coolant (which was sized for the original, fixeddisplacement auxiliary pump) with a hydraulic fan drive. The fan drive was thermostatically controlled based on engine coolant temperature.

22

september/october 2011

The drawback with this arrangement is, due to the engine being thermostatically controlled and the hydraulic system not, air flow through the combined heat-exchanger depends entirely on engine temperature. This meant the reduction in heat-load from replacing the fixed pump with a variabledisplacement unit resulted in a significant reduction in hydraulic oil temperature (normally a good thing!).

The engineers blocked off air flow to most of the hydraulic oil section of the cooler and ran the test again. This returned fuel consumption to the original level, but no significant improvement was seen.

It was concluded that the modification tested could result in a small cost saving with respect to a reduction in size of the oil cooler. But with fuel consumption being more important than any modest saving in cooling capacity, the idea of paying more for a pump that resulted in the oil being kept at a lower operating temperature—but increased fuel consumption—was irreconcilable to the machine’s designers!

One of the key take-aways from this case study is the impact hydraulic oil temperature, and therefore viscosity, can have on fuel consumption.

To re-cap the key points of the story: • The heat-load on the hydraulic system was reduced (efficiency increased) by replacing a fixed pump with a variable-displacement unit,

• this resulted in a (significant) drop in hydraulic oil temperature; • and the resultant increase in hydraulic oil viscosity increased fuel consumption by a meaningful amount.

In other words, if the hydraulic oil is too thick, the end-user will pay for it at the fuel bowzer or electricity meter. (The cautionary flipside to this though is, if the oil is too thin, the end-user pays for it at the repair shop).

Assuming the above trial was conducted at the same ambient temperature for both pump options, a 30°C drop in hydraulic oil temperature is quite remarkable.

This may in part be explained by the combination heat exchanger installed on the machine. As hydraulic oil viscosity increases, the engine works harder (burns more fuel) and so the cooling fan (controlled by engine temperature) runs harder, which means more heat is dissipated from the hydraulic oil and therefore hydraulic oil viscosity increases further. It’s kind of a viscous circle.

Another take-away from this story, which is pertinent to machine designers and by extension to the people who buy their machines, is most designers do NOT treat the oil as the key component of the hydraulic system that it is.

The hydraulic oil’s viscosity (weight), viscosity index, and the optimum viscosity figure for the hydraulic components in the system were apparently not considered during the test. This suggests that www.fluidpowerjournal.com | www.ifps.org

Ambient air Temperature

Installed Cooling Capacity

Fig. 1: The Power Efficiency Diamond designed efficiency

oil viscosity

the baseline or “normal” fuel consumption of the machine was just a happy coincidence.

Even after having discovered that fuel consumption goes up with oil viscosity, and although the possibility of reducing the installed cooling capacity was acknowledged and contemplated, there was apparently no consideration given to changing the oil’s viscosity to match the increased efficiency of the system. Nor was the ambient air temperature (or any variation thereof ) during the test mentioned, either.

In other words, the machine designers failed to properly consider all four sides of what I call The Power Efficiency Diamond of a hydraulic machine (Fig. 1).

Power efficiency means the ratio of power out to power in. In other words, 90 horsepower out from 100 horsepower in is an efficiency of 90%, 90 horsepower out from 110 horsepower in is an efficiency of 82%, and 90 horsepower out from 120 horsepower in is an efficiency of 75%. Note that in all three cases, output power remains the same at 90 horsepower; it’s just that the input power (and therefore fuel or electricity consumption) required to get it keeps going up!

The four sides of the Power Efficiency Diamond of a hydraulic machine (Fig. 1) are all interrelated; change any one and the symmetry or shape of the diamond is distorted.

Designed Efficiency reflects the “native” efficiency of the hardware chosen for the system: the number of power-wasting devices present, such as proportional valves, flow controls, and pressure reducing valves; and losses “designed-in” by the dimensions and configuration of all the necessary conductors (pipes, hoses, adaptors and manifolds).

On the opposite side of the diamond, Installed Cooling Capacity, as a percentage of continuous input power, should reflect the designed or native efficiency of the hydraulic system. In other words, the lower the native efficiency, the greater the installed cooling capacity.

Adjacent to installed cooling capacity is the Ambient Air Temperature the hydraulic machine has to operate in. This directly influences the hydraulic system’s operating oil temperature. And operating oil temperature largely determines Oil Viscosity, (“weight” of the oil used), which completes the Power Efficiency Diamond.

A machine designer has no control over Ambient Air Temperature—although he does need to know what this number is. But he does (or at least should) determine the other three variables: Design Efficiency, Installed Cooling Capacity, and Oil Viscosity. And as the pictorial representation of the Power Efficiency Diamond illustrates (and the above case study demonstrates), no one of these variables can be considered in isolation.

Looking at the Power Efficiency Diamond from an end-user’s perspective, it’s helpful to appreciate that even after the machine is designed, built, and filled with oil, Design Efficiency, Installed Cooling Capacity,

and Ambient Air Temperature are moving targets— moving targets that affect operating oil viscosity and therefore power (fuel or electricity) consumption.

The possibility of variation in Ambient Air Temperature, particularly if the machine is moved between locations with different climatic conditions, is fairly obvious.

And while Design Efficiency doesn’t vary, actual operating efficiency typically deteriorates over time, due to wear and tear. Similarly, while Installed Cooling Capacity, as a percentage of input power, doesn’t change over time, the effectiveness of it can be reduced—by wear and tear of cooling circuit components and, in the case of air-blast heat exchangers, variation in ambient air temperature and altitude.

So getting a hydraulic machine into its power efficiency “sweet spot” requires informed design. Keeping it there requires that the change in dependant variables be kept to a minimum. In both cases, The Power Efficiency Diamond can be helpful to both machine designers and end-users in understanding the task at hand.

PRESSURE TRAP B versus D LIP U-SEALS

By Sonny Goldsmith, Territory Manager, Hercules Sealing Products is the difference between a “B” lip u-seal and a “D” lip u-seal? When do you use one style and when should you use the other?

Before we discuss the two styles of u-seal lips, let’s briefly look at the evolution of the u-seal and how different lip styles came about.

The u-seal shape evolved from the vee ring. Initially the u-seal was a vee ring with a flat back or heel, and all u-seals were symmetrical in shape. Gradually the shape evolved, and instead of a sharp-pointed lip design, the “D” lip style was used on all u-seals to improve sealing effectiveness. In the late 1950’s, a major seal manufacturer introduced the bevel lip or “B” lip design. The characteristics of the “B” lip and the new geometry of the u-seal created a more effective seal.

Loaded u-seals were introduced as a cost-effective way to improve low-pressure fluid leakage. When the “B” lip design is utilized in conPiston u-seals junction with an energizer showing evidence of (o-ring / quad-shaped ring, etc.) in the u-seal, a very pressure trap failure

high radial loading is created at the seal lips, which provides very effective sealing and a very dry surface. In rod-sealing applications, this is a very desirable situation. However, in double-action piston-sealing applications, the effectiveness of the loaded “B” lip seal may actually create problems.

In piston-sealing applications, the primary purpose of the piston u-seal is to keep significant amounts of fluid from passing through the gap between the piston OD and bore of the cylinder. A slight amount of leakage past the seal lips is not a problem like in rod sealing. Due to the cycling of the piston and alternating high/low-pressure cycles of the fluid, some leakage past the seal lip is normal and not a problem.

However when loaded “B” lip seals are used in piston-sealing applications, their sealing effectiveness may actually be too good. As fluid bypasses the sealing lip on the high-pressure side of the piston, it will accumulate between the two seals and should be able to “leak” past the seal on the lowpressure side of the piston relieving the pressure buildup between the two seals. But, if the “B” lip seal on the low-pressure side of the piston seals too effectively, the pressure between the two seals begins to build up. As the pressure builds, it causes each of the two seals to seal more effectively and trap more fluid increasing the pressure even more.

As the pressure trapped between the two seals increases, it causes the seals to twist in the groove towards the outside edge of the piston (away from the center of the piston) until one of the seals eventually fails: pressure trap failure. This type of failure is typically indicated by one or both of the piston u-seals showing evidence of extrusion of the seal lip towards the edge of the piston (away from the center of the piston) as well as evidence of a twisting of the seal cross section. Typically, pressure trap is more likely to occur in applications where there is a very rapid cycling of the cylinders.

There are several ways to avoid this situation. One way would be to use non-loaded u-seals. Two unloaded seals could be used, or just one unloaded seal and one loaded seal. If using two loaded seals, using a “D” lip seal will lessen the sealing effectiveness of the seal and reduce the possibility of pressure trap between the two seals. Since the “D” lip seals less effectively, it is less likely to trap pressure.

“D” lip seals were specifically designed by seal manufacturers to be used in double-action piston applications to avoid the problem of pressure trap. However, if only “B” lip seals are available, they may be used by removing the energizer from one of the two seals. This reduces the lowpressure sealing effectiveness of the seal, which has the energizer removed (thus allowing the pressure between the two seals to by-pass the seal to the low pressure side of the piston), but has no effect on seal performance at high pressure.

Using unloaded u-seals, “D” lip seals, or “B” lip seals with the energizer removed, offers no guarantee of avoiding pressure trap. But it is less likely to occur if these steps are taken. The only way to avoid pressure trap is to use a piston designed for a single- piston seal.

Pressure Sensors Serve as Critical Components in Accurate Operation and Maintenance of Windmills

28

september/october 2011

ind energy offers an environmentally friendly fuel alternative to fossil fuel-generated electricity. Windmills are required to convert this “green” energy of the wind into electricity. Because of the remote location of many windmills, sensors serve as critical components in their operation, maintenance, and safety. Pressure sensors monitor yaw brake, lubrication oil, cooling circuit pressure, and level in gear boxes.

Differential pressure sensors monitor filter conditions. As a hydraulic filter becomes clogged, the output signal increases, notifying the controller to replace the filter.

As windmills are located in deserts, coastal areas, and mountaintops, operating temperatures can range from -50°C to 60°C. In addition, windmills are subject to salt, mist, and fog, a leading form of corrosion. Instrumentation used to monitor the operating conditions for the windmill, therefore, needs to survive in severe conditions while offering reliability and trouble-free service.

Pressure sensors, differential pressure sensors, and

pressure-temperature sensors from American Sensor Technologies are suitable for windmill applications.

In addition to being rugged, AST pressure sensors operate over wide ranges of temperature and environments, from deserts to coastal plains.

Products include: The AST4000 OEM pressure sensor offers high proof and burst ratings with EMC protection. It can www.fluidpowerjournal.com | www.ifps.org

be constructed as a millivolt output pressure sensor, amplified voltage output pressure transducer, or 4-20mA loop powered pressure transmitter. It covers a wide variety of applications that require rugged construction, high cycle life, as well as media compatibility to deliver long-term performance. The company’s Krystal Bond™ Technology provides the flexibility of the sensor to be used in virtually any OEM application. Whether measuring hydraulic pressure in a manifold or corrosive media such as seawater or hydrogen, this pressure sensor provides a thick diaphragm to maintain long-term stability and use.

The AST5400 differential pressure (DP) transducer offers filter condition monitoring with linear and accurate readings. It can measure line pressures up to 2000 psi with a turndown ratio of 15 to 1.

Using Krystal Bond Technology, the unit contains no silicone oil, O-rings, or welds. This MEMS pressure sensor technology completely isolates the media to the pressure ports, thus eliminating contamination risk. The low strain level on the diaphragm results in accurate, repeatable measurements. The transducer can be used to measure differential pressure across a filter, monitor level in a sealed or vented tank, or calculate flow across an orifice plate. With its digital compensation, the series offers good linearity and performance over temperature. If the transducer were to experience a fault condition, the transducer can be programmed to rail the output signal to 10% below the minimum or 10% above maximum output signal to notify the user of an issue and protect the system from undesirable conditions. The unit also offers flexibility in its configuration, allowing for a variety of wetted materials and pressure ports.

series is a solution to level monitoring for indoor and outdoor applications.

The AST4500 and AST4510 level sensors are completely sealed for submersion yet vented through the cable to correct for barometric pressure changes. The welded housing is tested in-house via a helium leak tester to ensure proper protection. The conductors of the cable are also isolated from the outside environment to keep the sensor operational for long-term use.

With a removable nose cone, the AST4500 and AST4510 series can be also installed outside of the tank through a 1/4" NPT pipe connection. In this configuration, the sensor continuously monitors the tank level through a threaded connection outside the

tank, yet remains fully submersible for applications with flood prone environments or severe wash-down conditions.

Available with voltage or 4-20mA output signals.

The AST20HA offers pressure and temperature readings from one device, reducing process penetrations in the hydraulic system. It is a digitally compensated 0.1% pressure transducer/ pressure transmitter that offers high performance over temperature. Krystal Bond Technology alone offers good non-linearity and non-repeatability performance. When it is combined with the ASIC, the unit offers high performance pressure sensing at an affordable price.

The AST4510 pressure sensor measures the level of an oil reservoir while offering temperature output as an option. Maintaining and monitoring the level of oil is critical to maintain smooth supply of power from the windmill. The AST4500 and AST4510 submersible level sensors are approved to UL/cUL913 (CSA 157) Class I Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier.

industrynews ESA 2011 Fall Technical Conference November 6-8, 2011 MSOE Offers Hydraulics Training to U.S. Navy

Sixteen members of the U.S. Navy attended Milwaukee School of Engineering (MSOE)’s “Introduction to Hydraulics” course. Dr. Medhat Khalil, MSOE’s director of professional education and research development, traveled to the National Maritime Intelligence Center (NMIC) in Washington, D.C., where he taught the course.

Dr. Khalil offered the class at the NMIC because the attendees wanted to learn more about hydraulics, control systems, and the relationship between hydraulic systems for use in Navy systems for improved reliability and operation. “Introduction to Hydraulics” is a 32-hour seminar designed to acquaint individuals with the fluid power field and provide a practical working knowledge of this important and growing industry.

As a result of completing this course, those naval members are able to identify the distinguishing features of hydraulic systems; apply industry standards to hydraulic and schematic symbols; analyze hydraulic circuits from a schematic drawing using animated schematics modeled by Automation Studio; explain the operation and applications of valves, cylinders, pumps and motors using animation and video clips; identify the chemical and physical properties of fluids as they relate to hydraulic system operation; utilize continuity and energy balance equations; and understand the basic configuration and operation of hydrostatic transmissions.

In commenting on the skills or techniques learned in the course, attendees noted they “learned how to understand schematics and different types of system components, and how they operate.” Another said they “learned about the workings of and relationships between valves, pumps, and accumulators.”

“Introduction to Hydraulics” is one of the professional education seminars offered through MSOE’s Fluid Power InstituteTM (FPI) that are endorsed by the National Fluid Power Association (NFPA) through sponsorship and educational partnership. The FPI is one of the leading academic fluid power research laboratories in the U.S., and it conducts research and testing for some of the largest hydraulic companies, as well as system evaluations for the U.S. military.

By offering this course at the NMIC, the FPI further expands its relationship with the U.S. military.

MSOE, an independent university with 2,600 students, is a member of the Engineering Research Center for Compact and Efficient Fluid Power (CCEFP), which develops compact, next-generation, fluid-powered devices for use in aerospace, agriculture, construction, health care, manufacturing, mining, and transportation.

High and Low pressures are separated by a sensor assembly consisting of a magnet, diaphragm and a range spring. The difference in pressure causes the assembly to move in proportion to the change against the range spring. A rotary magnet, located in a separate body compartment and isolated from the acting pressures, is rotated by magnetic coupling as per the linear movement of the sensor assembly.

A pointer attached to the rotary magnet indicates differential pressure on the dial.

Performance Enhancement and Efficiency Helps Win the Race

T

he RED Motorsport team has had an excellent start: In the first of six AvD 100-mile races of the season in Franciacorta, Italy, in mid-May, its Lotus Exige took first place in the GT4 class. The car was ranked 16th overall in a field of 31 participants. This success was equally shared by Evonik’s Automotive Industry Team (AIT), which sponsors the Lotus racing car, because the race was also a test-run for a new engine oil to which the company’s Oil Additives Business Line has contributed lubricant components.

“In conjunction with our strategic partner, Fuchs Europe Schmierstoffe GmbH, a new engine oil has been developed that significantly reduces fuel consumption and CO2 emissions,” says Norbert Westerholt, head of the business line.

VISCOPLEX® and VISCOBASE® are the lubricant components from Evonik that, as constituents of the high-performance engine oil, contribute to a significant reduction of friction in the engine. This leads to measurable improvement in performance as well as lower fuel consumption. And the new product is as easy on the environment as it is on the purse, because lower fuel consumption equals less CO2 emission.

Thanks to a sophisticated development process, the new 0W-20 engine oil was at the starting line promptly at the opening of the racing season.

“Because the technical requirements of the individual www.ifps.org | www.fluidpowerjournal.com

components were extremely high, we had partly to redevelop the products before producing him,” says Dr. Thorsten Bartels, head of the test laboratory for Oil Additives at Evonik in Darmstadt. Over the last year, Bartels and his team have optimized the newly developed high-performance lubricant on an engine test-bench and also tested it in racing cars under realistic driving conditions on a number of test tracks until it was ready for use in racing.

The Lotus model built for this season weighs just 780 kg. The reduced weight results from the use of various technologies from Evonik such as the ROHACELL® foam core in the bodywork.

For the AIT, which brings together the Group’s automotive experts, motor sports serve as the test field for series production: “Only those technologies that withstand the rigorous conditions of the race track can be considered basically suitable for serially produced vehicles,” says AIT Head Klaus Hedrich.

Meanwhile, testing of the newly developed oil on the engine test-bench and roller dynamometer continues at the company in Darmstadt. The lubricant is already undergoing long-term tests in a fleet of road vehicles.

New Certifications in Development: Mobile Electronic Controls and Industrial Electronic Controls The International Fluid Power Society (IFPS) awarded Task Trainers, LLC a contract to develop the new certifications. Task Trainers, LLC and a panel of industry subject matter experts will begin the development of the Fluid Power Mobile Electronic Controls (MEC) and the Fluid Power Industrial Electronic Controls (IEC) certifications. The Fluid Power Electronic Controls Specialist (ECS) was released in 2009, and the development of the MEC and IEC certifications complete the IFPS Electronic Controls certification levels. The MEC and IEC certifications are expected to be released at the end of 2012.

The IFPS Electronic Controls certifications are designed to review and test the understanding, specification, and application of electronics used in the fluid power industry from simple sensors and limits to HMIs, controllers, and networks. They include a review of applicable pneumatic and hydraulic principles as well as examples of the electronics for both mobile and industrial fluid power equipment.

“The IFPS strives to keep pace with changing flu-

id power and motion control technologies, and the development of the MEC and IEC certifications is a prime example,” said Jon Jensen, CFPPS, CFPECS, CFPAI, current IFPS president.

Beginning with the first Fluid Power Hydraulic Specialist certification in 1980, the IFPS has become the recognized industry leader in Fluid Power & Motion Control certifications. Fifteen different technical certifications are currently offered. These certifications cover diverse job descriptions within the industry including mechanic, technician, specialist, and engineer. The IFPS has nearly 10,000 active certifications throughout the United States and in many countries around the world.

CCEFP | The Center For Compact And Efficient Fluid Power

CCEFP Research

By Prof. Steven Jiang, Project 3A.3, North Carolina A&T State University

Human Factors in Fluid Power Systems:

I

Is It Necessary?

s it necessary to study human factors in fluid power systems? This is the question I am asked most often since the inception of CCEFP. My short answer is: Yes, because to err is human.

We humans make mistakes, and human error is inevitable. In fact, up to 90% of all accidents in the workplace have human errors as a cause. However, solutions to those problems are often technologically focused. It is important to understand that any system where human operators interact with the machines will have some human factors issues. Simply put, human factors, also known as ergonomics, studies how people interact with their environment and the goal of human factors is to provide efficient, safe, and comfortable equipment and work environments. Unfortunately, many system designers don’t think the role of human factors in fluid power systems is a very important one.

Consequently, much emphasis has been placed on improving machine performance and very little has been given to human operators. The truth is no matter how wonderful the system may be, if human operators are uncomfortable, or having trouble using it, you will not achieve the optimal system performance. More importantly, systems that rely on perfect human performance are fatally flawed.

Human operators have limited physical and cognitive capabilities, and these limitations will have an impact on the effectiveness of a fluid power system.

The technologically focused system design solution often fails to fully consider user capabilities and thus cannot achieve the full potential that the systems are designed for. To overcome this problem, human factors needs to be considered. In CCEFP, Project 3A3 (human performance modeling and user center designed) is focused on human factors research.

One of the common problems of system design is that usability of the system is only considered when the system is developed, and thus many system issues are not functionality problems but rather usability concerns. The problem with this approach is that fixing usability issues at this stage is often costly and not very effective. The more effective approach is the User Centered Design (UCD) philosophy. The idea 48

september/october 2011

is to place user needs and interests as early as possible into the design process. UCD is an iterative process, which includes collecting user needs, creating user profile, developing usability goals, performing task analysis, prototyping, usability testing, and implementation. Our research adopts a novel approach that integrates personal design and information sent to UCD. The effective use of the UCD approach can ultimately save companies money because there will be less maintenance and training-related expenses.

Another important human factors issue is human performance. Modeling human operator performance is important because it helps predict how operators

will perform given a new or revised system and can be cost effective before expensive prototypes or mockups are developed. Dr. Khaliah Hughes, who graduated in May, developed an integrated framework that combines the physical and cognitive aspect of human performance modeling and applied it to the excavator test bed using simulation tools such as Micro Saint and Jack. Her dissertation titled “Integration of Cognitive and Physical Factors to Model Human Performance in Fluid Power Systems� received the 2011 North Carolina A&T State University best dissertation award.

With rapid development of fluid power technology, there is a great opportunity for the fluid power industry to implement human factors and ergonomics initiatives that will provide them a positive return on investment (ROI). * Reprinted with permission from the Center for Compact and Efficient Fluid Power (CCEFP) newsletter, Issue 15, Spring 2011

Supporting Model-Based Systems Engineering

By Prof. Chris Paredis, Project 2E, Georgia Institute of Technology

with SysML

ontemporary systems engineering projects encompass many different domains of knowledge, exist at increasingly large scales, and consist of multiple subsystems and components. With the adoption of electrohydraulics, the complexity of fluid power systems has also increased significantly, requiring careful integration between fluid power, electrical, mechanical and controls, hardware and software. Studies generally show that problems associated with the development of such systems have often more to do with the organization and management of complexity than with the direct technological concerns that affect individual subsystems and specific physical science areas. If system designers do not fully understand the complexity and emergent behavior of the system under development, they might overlook important design details and relationships. Such mistakes can compromise stakeholder objectives and lead to costly design iterations or system failures.

To overcome such problems in the context of fluid power systems, the CCEFP is adopting a ModelBased Systems Engineering (MBSE) approach.

Specifically, a project on “Model-Based Systems Engineering for Efficient Fluid Power” started in June, and Prof. Rob Cloutier from Stevens Institute of Technology will join the Scientific Advisory Board to provide feedback on systems engineering research within the Center. In addition, through the activities of the Systems Engineering Task Force, concepts of MSBE will be infused in the test-beds and research projects within the Center. www.ifps.org | www.fluidpowerjournal.com

The MBSE approach pursued within the Center builds on the Systems Modeling Language (OMG SysML™) developed by the Object Management Group. SysML is a general-purpose information modeling language that allows system designers to create and manage models of physical systems using well-defined, visual constructs. The knowledge captured in a SysML model is intended to support the specification, analysis, design, verification, and validation of a complex system.

The specification of the SysML language reuses a subset of UML 2.0 and extends it where necessary. Adopted in November 1997, the Unified Modeling Language is a visual language for specifying, constructing, and documenting the artifacts of software, business models, and other applicable systems. It is a general-purpose modeling language that can be used with all major object and component methods. The language is commonly used during the development of large-scale, complex software for various domains and implementation platforms.

The SysML profile was developed to extend UML for increased support of systems engineering projects.

The <<block>> is the basic unit of structure in SysML and can be used to represent hardware, software, facilities, personnel, or any other system element.

The system structure is represented by block definition diagrams and internal block diagrams. A block definition diagram describes the system hierarchy and system/component classifications. The internal block diagram describes the internal structure of a system in terms of its parts, ports, and connectors. The package diagram is used to organize the model.

The behavior diagrams include the use-case diagram, activity diagram, sequence diagram, and state machine diagram. A use-case diagram provides a high-level description of functionality that is achieved through interaction among systems or system parts.

The activity diagram represents the flow of data and control between activities. A sequence diagram represents the interaction between collaborating parts of a system. The state machine diagram describes the state transitions and actions that a system or its parts perform in response to events.

SysML includes modeling constructs to represent text-based requirements and relate them to other model elements. The requirements diagram captures requirements hierarchies and requirements derivation.

The satisfy and verify relationships allow a modeler to relate a requirement to a model element that satisfies or verifies the requirements. The requirement diagram provides a bridge between the typical requirements management tools and the system models.

The parametric diagram represents constraints on system property values such as performance, reliability, and mass properties, and serves as a means to integrate the specification and design models with engineering analysis models.

SysML also includes an allocation relationship to represent various types of allocation, including allocation of functions to components, logical to physical components, and software to hardware.

SysML models are being used in several research projects and test-beds within the CCEFP. For instance, in the rescue robot test-bed, the requirements are broken down into detailed requirements and corresponding test cases as is illustrated in Fig. 1.

The use of SysML for requirements capture, system descriptive models, analysis models, and the relationships between these different system views is applied extensively in Project 2E on Model-Based Systems Engineering for Efficient Fluid Power.

To learn more about the Systems Modeling Language, visit www.omgsysml.org where you can find several introductory tutorials and papers. The SysML movement is quickly gaining momentum with several major software vendors supporting the standard (for a list of vendors consult the site above).

Fluid Power Scholars and REU Program Underway for 2011

By Alyssa Burger, Outreach Director, University of Minnesota The CCEFP’s Education and Outreach Program extended a warm welcome to the participants of the 2011 Fluid Power Scholars Program and the 2011 Research Experiences for Undergraduates Program.

The Fluid Power Scholars (FPS) Program is a collaborative effort between the CCEFP and corporate members of the Center. This program identifies and connects outstanding undergraduate engineering students with the fluid power industry for the purpose of training the next generation of fluid power leaders by offering a three-day fluid power boot-camp followed by a summer-long internship within the company. 2011 is the program’s second year, and just like the first year, eight scholars have been named.

The Center thanks the internship host companies for their support: Case New Holland, Parker Hannifin Corporation, Sun Hydraulics, HUSCO International, Caterpillar, John Deere, and Deltrol Fluid Products.

The Research Experiences for Undergraduates (REU) Program’s goal is to provide undergraduate science and engineering students with a summer experience in a university research lab. An objective of the program is to increase the number of top students applying to graduate school in science and engineering areas. The Center welcomes 18 REU students to the 2011 program.

For the very first time, the program hosted 11 REU students at the University of Minnesota for a Fluid Power Boot-Camp, lead by CCEFP graduate students, to fully prepare REUs in fluid power technology for their summer research experience.

IAB Holds Second “On Campus” Meeting; GT Hosts

By Brad Bohlmann, CCEFP Sustainability Director, University of Minnesota The CCEFP Industrial Advisory Board (IAB) held a meeting at the Georgia Institute of Technology on May 4 and 5. Eighteen IAB members met with a total of eight principal investigators (PIs) from Georgia Tech, Vanderbilt, and North Carolina A&T State to get updates on their research and discuss future research potential. In addition, the IAB toured the Center-related lab facilities at Georgia Tech.

The IAB decided in late 2010 to hold three or four of its meetings each year at CCEFP member universities. The plan is to visit all seven universities on a rotating basis. The meetings are done on a regional basis, so PIs from member universities within driving distance of the host university are also invited to attend and meet with the IAB. The meeting at Georgia Tech was the second on-site IAB meeting.

The first on-site meeting was held at the University of Minnesota in November 2010. The next on-site meeting is planned for Purdue University in September.

The entire first day of the meeting was focused on the IAB meeting with PIs and touring the lab facilities. The goal was to have a dialogue between the IAB and PIs—as opposed to a lecture—and this was largely accomplished. That evening, CCEFP hosted a dinner for the IAB, PIs, students, and staff that provided an opportunity for networking and individual discussions. The majority of the second day was focused on IAB-related topics and included a presentation by CCEFP Director Kim Stelson on the sustainability of the Center. The new industrial liaison, Dewey Tinderholm, was introduced to the group.
