Training and Certification are the Keys in Fluid Power Today

T

oday’s global manufacturing using fluid power can No Longer use the old hit-and-miss approach, “IF IT’S NOT BROKEN then DON’T FIX IT.” With today’s complex machinery, high production schedules, just-in-time inventories, fewer maintenance personnel, and the prohibitive cost of downtime, many end users cannot afford to operate in the old manner. This is why many end users – due to downsizing of their maintenance staffs – are starting to rely on the original equipment manufacturers (OEMs) to supply trained personnel to accomplish routine pro-active maintenance tasks. However, many end users are still encountering problems when trying to use OEM’s service personnel to answer end user complaints. Two causes for this problem are purchasing equipment offshore and downsizing the OEM’s engineering and service maintenance personnel.

Today, fluid power control suppliers and their distributors are being called on to supply trained and certified fluid power personnel to perform the necessary tasks to keep this sophisticated equipment up and running. Control suppliers and their distributors are in turn relying on welleducated and IFPS-certified personnel from Key Schools (community colleges who are teaching their students to be certified and trained in fluid power troubleshooting and equipment applications). Here are some examples of systems and equipment aspects in which Key School students are trained: TROUBLESHOOTING: • Clogged /dirty oil filters • Excessive temperatures • Insufficient oil in the reservoir(s) • Loose intake lines • Improper grades of oil (too heavy or too light) • Pump shaft rotating in wrong direction 4

• Operating pressures set incorrectly for all pressure control valves (relief, unloading, sequence, counterbalance, brake, and pressure reducing) • Improper settings on flow control valves and pilot-operated check valves • Air leakage • Fluid contamination • Systems faults (heat, noise, vibration, laser alignment, and leakage) • Pumps and motor (cavitation, fluid aeration) DESIGN: • Accumulator sizing and safety • Actuators (linear and rotary cylinders, hydraulic motors) • Directional control valves, proportional control valves, safety enabling valves • Cartridge valve sizing • Heat exchangers sizing

The major expenses incurred in carrying out a proactive maintenance program can be recouped many times over. This recovery of expense is due to reduced operating and installation cost, as well as savings in machinery downtime. Less downtime leads to more equipment uptime, which can provide longer life of the equipment.

Remember, in order for a pro-active maintenance program to work, its plan must start at simultaneous engineering. This is where the OEM, End User, and Control Suppliers meet to resolve any issues or concerns. The OEM fluid power engineer shall design and make the selection of quality components, ease of maintenance, trouble-shooting, access for flushing and adequately size piping, tubing, and hoses.

The OEM will also provide fluid power systems’ calculations including those for cylinders, pumps, motors, and reservoir sizing.

At equipment run-off on the OEM‘s floor, extra attention shall be placed on proper installation of all components, cleaning of all pipes and tubing, and sufficient attention to any potential system leakage, vibration, filtration, noise, laser alignment, and equipment cycle time.

Once the fluid power system has been filled with a good quality fluid meeting manufacturers’ recommended specifications, such a fluid power system should provide efficient and trouble-free operation. To assure that this kind of performance continues, a reasonable amount of care is required. When the fluid itself serves as a lubricant and built-in overload protection, a hydraulic system is reasonably self-sufficient. Like any other mechanism, the hydraulic system should be operated within recommended system requirements. Overspeeding, over-heating, excessive pressures, and fluid contamination all tend to reduce the fluid power system efficiency, thus leading to shortened machinery life. www.ifps.org | www.fluidpowerjournal.com

Well-trained and certified fluid power personnel will recognize the signs and symptoms of impending concerns within the system application. In today’s global manufacturing, the equipment operators can be also trained to listen for any unusual noises, measure for excessive operating temperatures, and check for signs of external leakage or oil deposits around their equipment. Trained and certified maintenance mechanics or technicians can, at a glance, note the color of the fluid and its level in the reservoir’s sight glasses. Dirty or discolored oil would indicate the need for changing cartridges within the system and possibly the fluid itself.

Over the past 40 years it has been estimated that as much as 70% of all hydraulic issues and concerns have traced directly to problems with the fluid. Hydraulic pump noise may be the result of normal wear, but it could also be caused by (1) cavitation due to a clogged inlet filter, (2) fluid viscosity too high, (3) fluid temperature too low, (4) clogged reservoir breather, (5) a pump too far above the reservoir, (6) the pump too far from the reservoir, (7) excessive pump RPM, (8) too many bends in the pump inlet line, or (9) a restriction on the pump inlet line. Aeration may be caused by (a) low reservoir fluid level, (b) defective pump shaft seal, (c) return line above fluid level, (d) improper baffling in the reservoir, (e) loose fitting on pump inlet line, (f ) defective seal on the pump inlet line, or (g) porous hose on the pump inlet line. If noise is due to an air leak, the fluid in the reservoir will usually be covered with foam. Once entrained in the fluid, air causes spongy or erratic movement of actuators (cylinders and motors).

Slow or sluggish actuators in a fluid power system could be the result of low oil temperature or fluid with viscosity too high. More often it is a result of internal leakage through the actuator or one of its pressure

control components. A worn pump, too, might be the culprit if the actuator moves slowly, but if the actuator doesn’t move at all, the pump would have to be slipping its full delivery, and this is highly improbable.

Mounting bolts or brackets that are loose will allow misalignment of the actuators and pump or motor shaft which, if not corrected immediately, will result in shaft seal and packing wear if not more serious system or component damage.

Proper pro-active maintenance will keep fluid issues and troubles to a minimum. However, it is obvious that not all issues and concerns will be eliminated. Troubleshooting should be a regular part of maintenance procedures. Well-trained and certified fluid power personnel should lead to another advantage, that of having better reports and records.

Such records shall include • A description of symptoms and the date detected • Description of preliminary investigation and its results • Explanation of corrective action taken, replacement components required, date repairs made, and length of machinery downtime • A record of when the fluid is added or changed, as well as filter cartridges replacement Analyzing fluid power engineering data (records and reports) frequently will indicate areas that require special attention. They should highlight recurring problems that may be anticipated and corrected before equipment downtime occurs. Remember the old saying: “Pay Me Now or Pay Me Later.” Past experience shows when you “pay me later,” the cost usually increases by 75%. This is why it is very essential in today’s global manufacturing environment that proactive maintenance is a must. Certified and well trained personnel will make sure the above processes are carried out and equipment is maximized.

Correction

In the May/June 2011 Notable Words article by Kim Stelson at CCEFP, it was incorrectly written that the U.S. consumes approximately 100 Quads (1 Quad is 1015 BTUs) of energy each year. It should have been 1015 BTUs. july/august 2011

Mathteasers New Problem: Single Acting Pneumatic Cylinder 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.

previous problem: Heat Transfer Rate (From May/June 2011 Issue)

Illustration: John Spisak

A hydraulic reservoir is mounted so that the air will circulate freely around the reservoir.

The reservoir has the following measurements: • Hydraulic fluid is 1.5-ft deep in the reservoir, 1-ft by 2-ft.

• Hydraulic system temperature is 1300°F. • Air temperature is 700°F. Remember: You need to determine the reservoir surface area that is contacting the hydraulic oil.

Find the maximum heat transfer rate from the reservoir in Btu/Hr. In this example, for steel tank with a natural airflow directed toward it but not forced, use the number 10.

Anyone who submits the correct answer before the deadline date will have his/her name printed in the Society Page newsletter and in Fluid Power Journal. The winner will also be entered into a drawing for a special gift.

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 ft x 2 walls = 3 ft2 Then calculating the reservoir bottom: Area = 1 ft x 2 ft = 2 ft2

Therefore the total contact area would equal 11 ft2 Q = C x A x ∆T = (10 BTU’s / hr x ft2 °F) x 11 ft2 x (130°F- 70°F =

Q = 6600-Btu's / hr.

Green Air: part 5

r i A d e l c y Rec Greater attention to compressed air saving and efficiency can boost productivity. The first two sources of partially preventable compressed air cost may be leaks and pressure drop. A contender for third place is failure to recycle the air.

One of the most common uses of compressed air is with linear actuators, cylinders to push, pull, lift, clamp, or to provide force. Probably over half of those cylinders are used in one direction, and then returned or retracted to prepare for the next stroke.

Except for a small difference in volume on the return stroke due to the space occupied by the piston rod, the air consumed is doubled, pushed out and pulled back. Why? It appears this was the simplest way to do it. Now with the cost of energy, carbon tax, need for more efficiency, and all the above, it is time to change the game plan.

A previous technical paper printed in this column and still on the IFPS Web site titled “Cylinder Possibilities” touched on the topic of recycled exhaust air. Not long ago, one of the trade journals had an article about recycled exhaust air that mentioned a possible 30% reduction by returning exhausted air to the compressor intake. Some local uses would benefit also.

Focus on the total operating cost not the initial cost of components. For a drop-dead simple way to start saving air, purchase cylinders with oversized rods. The smaller volume in the rod end of the cylinder saves on every cycle with no complexity. Invest more initially and enjoy continuous payback day after day. When the compressed air has been compressed, dehydrated, filtered, transported, regulated, and lubricated at considerable expense, it should not be dumped to atmosphere after one use. Given consideration, the high-pressure exhaust might be dumped into a lower pressure manifold. Consider the following: 1. A sincerely simple way to recycle compressed air would use about 30 psig to return those cylinders that only work in one direction: • With 30 psig connected to a constant pressure as an air spring • With dual pressure valves that use low pressure for return air

In either case, the cylinder is stroked one way with clean lubricated pre-used air.

2. OSHA requires blow guns be limited to 30 psig. Use the “free” air.

3. Extend cylinders with 30 psig and “Top up” to higher pressure for force.

4. Use air bags for high force and fill the ample volume with recycled air.

5. Instrument air at 20 psig can be cleaned up and regulated easily.

6. Use a return line to the compressor and as a low-pressure manifold.

7. Alternative reservoirs can be local storage for recycled air.

Obviously the low-pressure volume must have a regulated supply from the main air to make sure that pressure is available until adequate recycled air builds up.

In the plumbing that is supplied with recycled air, if the air carries lubrication, there will be less rust and corrosion. Leaks in this plumbing will waste less air due to lower pressure. Applications like air for blow off, air curtains, air knifes, fumes, and exhaust amplifiers may utilize recycled air possibly filtered to remove oil.

With big ideas and small changes, a 10% saving is almost assured, and 25% could be achieved if only some of the air used is recycled air. When reading claims like “manufacturing may use as much as 50% of all energy and compressed air uses 30% of the electrical energy in many plants,” the enormity of a 10% saving is mind boggling and very green.

From Top to Bottom: Polymers for Jack-up Rigs

By Trelleborg Sealing Solutions Americas

F

rom down hole drilling motors to oil platform tensioner systems, from subsea valves to refinery separation equipment, polymers and plastics play a vital role in the oil and gas industry. Seals, bearings, hoses, and other products are used throughout a variety of systems for exploration, completion, production, and refining activities. One such application is the jack-up rig.

Jack-up Rigs Jack-up rigs are mobile oil platforms that spend a majority of their life anchored motionless to the ocean floor, thanks to a number of supporting legs. Most jackup rigs are equipped with three independent supporting legs, but some can have four or more. Jack-up rigs are essentially a self-contained combination of a drilling rig and a floating barge. A workboat or tug tows the rig, legs up, to the desired location, where the legs are lowered and driven into the sea floor. The legs are pre-loaded to 10

July/August 2011

penetrate the floor to a predetermined depth, and when they are in place, the jacking mechanism attached to the barge and drilling package is raised. This all results in the entire jack-up rig structure being incrementally raised above the water to a pre-planned height.

In such an arduous environment as offshore oil and gas, there are many safety-critical applications. These include cranes where greaseless bushings and wear pads in composite materials, such as Orkot®, ensure lowfriction performance inside articulating joints. In the

iron roughneck, where superior load capability and wear resistance are important, these same materials can also be used as rotational flange bearings as well as on the sliding derrick, which is used to reposition the drilling equipment or offset drilling operations.

Fire Safety and Anti-Vibration When it comes to fire safety on the jack-up rig, metal O-Rings, like Wills Rings®, are used in flare applications to allow leak-free connections at temperatures above +600°F and also in high pressures. The Elastopipe™ system from Trelleborg Offshore is a patented piping system designed for deluge and sprinkler systems in harsh environments with exceptional impact, abrasion, explosion, water hammer and jet fire resistance (Jet fire conditions are +2,553°F for one hour). Elastopipe™ www.fluidpowerjournal.com | www.ifps.org

is made with a layered synthetic rubber construction and replaces rigid steel, titanium, copper nickel and fiberglass piping. Elastopipe's unique features make it a corrosion-free system that is ideal for deluge and sprinkler systems as well as other liquid transfer system on offshore oil and gas installations, ships and in other hazardous environments.

To isolate the jack-up rig from potentially damaging vibration, custom-designed anti-vibration mounts (AVMs) and shock pads can be used. These elastomeric mount units are located underneath the support skid.

In the event of exposure to a fire the outer rubber surfaces of the mount would char, forming a protective barrier. Even in a severe fire, ANDRE AVMs will not fail catastrophically but take on further settlement while supporting the skid.

On the deck of the jack-up rig, Vikodeck is an option.

This passive fire protection system offers protection to the deck surface from hydrocarbon and jet fires aboard jack-up rigs. It is blast- and seawater-resistant.

Trelleborg's Drain Gully allows easy connection of deck modules accommodating normal building tolerance between sections. The flexible system is designed to operate maintenance free and move in all directions over the life of the platform, rig or vessel. It enables the design of a closed deck which eliminates the need for fireproofing of process deck structures.

Circle 443

Underwater When the jack-up rig’s supporting legs are driven into the seabed, seals are needed to close the gaps between the transitions and the piles. The seals need to withstand high pressure and compensate for any misalignment that might occur. In these instances, inflatable grout seals, either passive or self-activating, may be used.

Mate Chief Petty Officer. I had had my adventures Tom Blansett and was ready to try civilian life. I began working for Vickers in the late 1980s as an instructor, and that led to various roles in sales and engineering over the years until today’s current position.

Q: When and where did your career in the fluid power industry start?

My career in fluid power actually began in 1978 when I reported to the USS SilQ: What is the most memorable moment in your fluid power career versides, SSN-679, a fast attack submarine home ported in Norfolk, Va., as a newly and what did it teach you? minted nuclear power mechanical operator. I met my Leading Petty Officer who took There have been many memorable moments in the past 33 years, and I am hard me under his thumb (I mean wing) and began learning about hydraulics, which are pressed to single out just one. Certainly one that I remember quite well and that has led critical to a submarine’s operation. Diving, steering, and other systems utilize hydraulics, to many subsequent successes was when I first attained my certification as a Certified and of course it runs 24/7 and must be absolutely reliable with no unplanned downFluid Power Specialist #1329.

than I, he treated me as a peer when we were teaching together at Vickers. I learned a lot from George (who was doing contract teaching for Vickers after his retirement) in many of our customer classes that we taught together. He was a proponent of the Fluid Power Society and was instrumental in the founding of the organization. He instilled within me a desire to want to work within the Society at some point in my career.

Q: What do you feel is the most important achievement in the fluid power industry?

I know many will speak of electrohydraulics as being the most important milestone in our industry, and I won’t argue how important that is. But having worked both as a mechanic as well as an engineer in the industry, my selection would be the adoption of the ISO Cleanliness standards for hydraulic fluids. That and the growing realization within the industry of just how critical fluid conditioning is especially when using smart electrohydraulic components, as they are quite sensitive to contaminants within the system. We all know proper fluid maintenance is essential to a reliable system. Looking back on my Navy days, and knowing how important the hydraulics were to us on a submarine (they ran 24/7 at moderately high pressure) and we never had any system malfunctions. This success, due to the fact that the system was well designed and because the fluid was properly maintained, really made me a believer in how important fluid conditioning is to a hydraulic system.

Q: How and why did you get involved in the IFPS? I had become certified many years due to the influence of George Nordenholt who was my manager when I began with Vickers. George was very active in the Society and decided that all of the instructors must become certified as a Fluid Power Specialist. I achieved that and maintained my membership and certification status for many years before I was active in the Society, primarily because of my geographical location (many years in Montana) where the number of members locally was small and also my roles in sales where I was traveling frequently. I have always recognized the benefits of the IFPS to our industry and to the individuals that comprise the membership, and knew that if I ever got to the stage where my location and/or job changed then I would seek out a more active role. Both changed in 2007 when I moved to the Midwest to become manager of Training Services. I got involved with the ECS development and then became a Board member, and I am now proud to be able to serve my fellow members.

Q: Why do you feel the IFPS is important?

The IFPS mission is to advance the technology and professionalism of the fluid power industry through awareness, education, and certification. By continuing to certify and promote highly skilled individuals in the industry, we have the ability to change the way in which fluid power is viewed and help it to grow and expand through more individuals participating within the Society. I am encouraged by the many new faces I see at the meetings now and by their high degree of enthusiasm and willingness to become active. Individuals joining the Society have a platform to be heard in the industry and can help increase awareness of the positive attributes of the use of fluid power.

Q: What have you personally gained by being a part of IFPS? I have gained recognition within the industry based on the certifications I hold and more importantly, I have met and become friends with many people that share as I do the belief that we can make a difference in the industry and be a positive influence. I enjoy the camaraderie of my friends while serving as a volunteer on various projects and committees within the organization, and enjoy the satisfaction that what we do is helping our industry to grow and prosper.

Q: Where do you see the fluid power industry heading in the next 10 years?

I think that we are only seeing the tip of where will be in 10 years in regards to advances in technology of coupling electronics with hydraulics and pneumatics. We will see many more “smart” components that incorporate not only the necessary processor to control the component operation but also embedded diagnostics that allow for real-time data acquisition to monitor not only component functionality but coupled with other smart components to allow for extremely accurate and precise control to optimize the efficiency of the system. These smart components will be multi-functional and will expand the capabilities of the system while at the same time resulting in a smaller envelope.

I look forward to helping the industry continue to grow and increase its popularity over other types of power transmission while losing its past reputation of being powerful but prone to problems such as leaks and reliability.

This is an industry that rises to and meets incredible challenges, and the best minds from around the world come together at OTC to share our knowledge, to learn about technological advances and innovative approaches, to solve problems and to discuss important issues that affect the entire planet,” said Susan Cunningham, 2011 OTC chairman.

This year’s event offered one of the strongest technical programs ever with speakers from every major global producing area. A primary focus of the conference was the impact on deepwater drilling of the Macondo accident in the Gulf of Mexico, www.fluidpowerjournal.com | www.ifps.org

with 11 sessions presenting government and energy leaders discussing the lessons learned to take forward across the globe. OTC’s Spotlight on New Technology program highlighted 15 innovative technologies that are already making the industry more effective.

The inaugural Annual OTC Dinner was attended by more than 1,000 industry leaders and conference attendees, and raised $200,000 for the Gulf of Mexico Foundation. OTC also presented its 2011 Distinguished Achievement Awards at the sold-out event Sunday at the George R. Brown Convention Center.

“The health and sustainability of the Gulf of Mexico is vital to the businesses that work in and alongside it. Recognition by the Offshore Technology Conference is the culmination of decades of collaborative efforts between the Gulf of Mexico Foundation and the offshore industries to understand and protect the quality of the Gulf of Mexico ecosystem,” said Gulf of Mexico Foundation President and CEO Quenton Dokken in accepting the OTC donation.

OTC continues to grow with two new conferences being held in 2011. The OTC Arctic Technology Conference was held in February in Houston, focusing on both offshore and onshore technology for Arctic exploration and development. OTC Brasil, focusing on global deepwater projects with a special emphasis on Brazil, will be held in Rio de Janeiro in October, and is attracting strong exhibitor interest.

The 2012 OTC takes place April 30-May 3 at Reliant Park.

"Highest Attendance and Largest Exhibition since 1982"

Safety Focus

Unsatisfactory hose storage conditions

Beware of getting

HO$ED

By Jamie Vokes, CFPCC, member of IFPS Chapters 49 and 50

July/August 2011

arious kinds of mobile and industrial equipment use hydraulics in one form or another. While hydraulics is a very efficient use of energy to perform heavy-duty operations, very few people take the time to investigate some of the component parts of a hydraulic system. Even fewer have a formal inspection or maintenance programs in place. This can lead to costly downtime but can also lead to more sinister safety and liability issues.

Who really pays attention to a hydraulic system until it stops working? Some of the common causes of breakdowns include parts wearing out, contamination, oil leakage, or the failure of a part that releases hot oil previously contained at thousands of pounds per square inch.

A pinhole leak in a hydraulic hose that’s under pressure can release fluid at a speed of more than 600 ft per second—which could easily penetrate the skin and enter the bloodstream. (As an example of the personal devastation caused by a safety-related accident in the fluid power industry, refer to “The Effects of Fluid Injection Accidents, An Employee’s Own Story” in the March/April 2011 issue.)

Owning and operating hydraulic equipment requires a maintenance program that is implemented by staff members or contractors who have been fully trained to be aware of the dangers of energy stored inside hydraulic systems. These people also need to be aware of how to safely affect repairs on the machinery or equipment.

Usually the most visible parts of a hydraulic system are the hoses or pipe work, which transfers the highpressure oil from the pumps and valves to the cylinders, motors, and actuators. The more visible and exposed these parts are, the easier they are to damage or even worse, cause injury.

Let’s take a closer look at the flexible hydraulic hoses in these applications. Do you have people within your organization who replace hydraulic hoses or do you subcontract this work out? Over the years, some companies have chosen to purchase a kit that gives them the capability of assembling and crimping hoses in-house. At first glance this may appear to be a very cost effective solution, but is it?

If you make your own hoses have you considered…

Training: Who carries out this task? Is the individual properly trained in the removal and installation and assembly of these hoses? Are they the individual who was originally trained by the vendor who supplied the hose-making equipment or is it somebody else?

Equipment: How old is the equipment? Does it need servicing or regular calibration? Should you be carrying any extra insurances or liability coverage?

Contamination: Do you have a method for cleaning the hose prior to installation on equipment?

Debris from cutting a rubber hose is one of the easiest ways to introduce contamination into a hydraulic syswww.fluidpowerjournal.com | www.ifps.org

tem. The facility and environment where coils of hose are stored can easily contribute to contamination.

Inventory: Did you know that coils of hydraulic hose have a shelf life? That is why a batch code with a cure date is placed on high-pressure rubber hose. Do you have a system for monitoring the shelf life of your hose inventory? Did you initially get the hose assembly equipment for free providing you purchase the product from the same vendor? This usually means you were loaded up with a lot of inventory that you may not use.

Mixing and Matching: Does your vendor use compatible hose and fittings? Are they manufactured by the same vendor, or are they mixed and matched from different manufacturers? Mixing and Matching can lead to loss of liability coverage and warranty as well as early failure of parts. Or worse, hose assembly failure or even a fatality.

Safety: Making hose assemblies may not be rocket science, however, it is a fact that an incorrectly assembled hydraulic hose could lead to serious injury of your employee, a customer, or even an innocent bystander.

Vendor: Have you asked for the necessary paperwork including safety and training manuals, insurance coverage, source traceability, as well as any relevant MSDS sheets?

By no means does this cover all of the considerations that need to be taken into account if you are deciding to make hoses in-house. They are designed to be a guide in the decision-making process. These points also

apply if you go to a hose shop to buy replacement hose assemblies or call out a contractor or mobile service to carry out the repair or installation.

Do not get unexpectedly hosed by finding out that an employee is not properly trained to work on the equipment you operate. If you find yourself visiting them in the emergency room, it is too late.

Do not get unexpectedly hosed by finding out your vendor is mixing and matching parts especially on component hydraulic hose parts. If you find yourself looking at a large claim with no vendor coverage, it is too late.

Do not get unexpectedly hosed by not having the correct paperwork, equipment maintenance programs, and insurance coverage in place. If you are looking back at an OSHA representative without an answer, it is too late.

Safety, training, and the selection of the correct replacement products, services, and vendors to replace hoses and other components in hydraulic systems can save your company the negative publicity of an unfortunate accident associated with high costs of corrective action or a claim that you may find out may not be covered by your vendor or insurance company.

Cycle

Rates Fig. 5

By Daniel Pascoe

In

modern day manufacturing, quick cycle rates are key to profitability and eventual production facility success. This is no different in vacuum pick-and-place applications. Vacuum handling cycle rates (the speed at which a product is picked up, moved, and released) is often the measurement taken as to the effectiveness of selected components.

Fig. 1

Fig. 3

Fig. 2

If handling large sheets of lumber or tiny electronic components, the cycle rates should be considered before anything else. How many parts per hour? How many parts per minute? The weight of a product being handled is often the first question asked but is rarely an issue as the surface area of the product is really smaller than that required to hold its weight with a vacuum cup(s).

A single square inch of surface area can offer over 14 lbs of lifting force, for example.

One of the mistakes often seen is the installation of a large vacuum pump or generator that has been chosen to offer vacuum level achievement in the required time span for product pick up. However, different installation techniques and component choice offer a much more economical and sensible solution to quick, accurate, and reliable application success.

Fig. 1 shows two very simple options for a vacuum pick-and-place system. The port designations on the generator are P-compressed air supply, V-vacuum inlet port, and R-venturi exhaust port. Option One uses one vacuum generator (air-powered venturi) to supply vacuum to all four vacuum cups. The problem with this system, although low cost, is the evacuation time between the venturi and face of each vacuum cup. Each time the cycle starts, the generator has to start from zero and then create a vacuum in the now closed system (between the venturi inlet and cup face sealed against the product).

As shown in Fig. 2, which shows a venturi time chart for a known volume, the time taken to get to a safe working vacuum level could be the difference between success and failure. Depending on the generator chosen and particularly if the RED connecting tubing are long and of a large diameter, the evacuation time could be well outside of the user’s specification. Every manufacturer should provide evacuation timetables for this purpose.

The exhausting of the vacuum (release of the product) is also extended, which will increase the total cycle time of the process.

Option Two shows the same vacuum cups, but each cup is attached to its own dedicated vacuum generator.

This decreases the amount of tubing that needs to be evacuated, and if the generator is mounted directly to the cup, the tubing volume is removed altogether. However, using one generator per cup consumes more compressed air, and this could be considerable on some machinery that uses many vacuum cups in its process.

Vacuum pump manufacturers would argue that an electrical pump does not use compressed air,

www.ifps.org | www.fluidpowerjournal.com

and this is a valid consideration in some cases where a compressed air supply isn’t available. However the pump cannot be mounted directly to the vacuum cup and often not even close, due to their physical footprint size and accessibility requirements for maintenance purposes. Capital cost of vacuum pumps is also higher than air-powered venturi systems in most cases.

A solution for faster cycle times is the use of a vacuum valve (as shown in Fig. 3) and a reservoir or vessel. Vacuum valves can be mounted close to the vacuum cups with the vacuum source, be it a vacuum generator or pump, and can be placed at the base of the machinery. The vacuum vessel provides a storage medium that offers virtually instant vacuum to the cups as soon as the vacuum valve is actuated. Fig. 4 shows a circuit that uses a generator, storage vessel, and a vacuum valve.

The generator cycles on and off using a pneumatic vacuum switch that is connected to the vacuum vessel. A more efficient multi-stage generator (compared to a single-stage unit) such as the model shown in Fig. 5 is also used. The generator only

Fig. 4

july/august 2011

19

operates when the vacuum level in the system requires recharging.

Fig. 6 is a graph demonstrating the cycling of the generator.

The first green line is the charge of the vacuum circuit. As the vacuum valve turns on and off, supplying vacuum to the cups, the vacuum level falls incrementally, as shown by the red line. The volume of tubing between the valve and the cups will determine how much vacuum is “used” and depending on the size of the vacuum vessel, how often the generator is turned ON. The switch used in this example has a differential of 3"Hg. The generator turns ON when the system vacuum level falls to 22.5"Hg and turns OFF when the system vacuum level reaches 25.5"Hg. Therefore this system offers extremely quick “ready vacuum” to the cups and also minimizes compressed air consumption as the generator is only on when it needs to recharge the vessel. The same system can be used with an electrical vacuum pump.

However, electrical vacuum pumps are normally coupled to a much larger vessel to prevent the pump from continuously cycling on and off, which is not good practice with electrical motors.

The vacuum valve as shown in Fig. 3 can cycle more than 10 times a second, so in extremely fast packaging lines for example, this method of vacuum control offers very rapid pick up and release of product being handled.

If this system is being used on a slower cycle rate application, the vacuum vessel will also offer a safety feature if compressed air is lost during the lift stage of the process. On non-porous surfaces such as steel or glass, this system could hold the part indefinitely without compressed air being present—a possible consideration, particularly when handling heavy or valuable loads or when personnel could be hurt by falling product.

As in any industrial application, there are many ways to achieve the finished result. The cost and effectiveness of these systems are open to discussion with many methods and components available for use from various manufacturers. The suggested method in the preceding text is simply one example of good component choice, where a fast cycle rate is achieved without unnecessary expense.

Hard chrome plating was first developed in 1856 and became a commercially viable product in the late 1920’s and has proven to be a reliable process in countless applications for many decades. However, growing concerns about environmental and worker safety have forced the development of new advanced technologies to replace chrome plating with safer, stronger, high-density surface coatings.

In the 1990’s a Hard Chrome Alternatives Team

The HVOF Process

(HCAT) was formed to evaluate and develop alternative processes. This organization is a North American team comprised of the U.S. Department of Defense, Canadian Military, U.S. and Canadian aircraft manufacturers, and many supporting organizations. The original intent was to evaluate several emerging technologies that included arc spraying, plasma spraying, flame spraying, and high-velocity oxygen fuel (HVOF). Since then, HVOF has become the preferred method of choice and is being rapidly adopted by OEM manufacturers and repair organizations as an alternative to hard chrome plating.

Applied Industrial Technologies, a North American fluid power distributor, has switched to HVOF for repair of hydraulic cylinders in most of its applications.

Warren E. (Bud) Hoffner, vice president, general manager - fluid power claims, “The HVOF process allows us to provide customers with a cylinder repair coating that lasts longer and has better corrosion resistance than the original hard chrome plating. The process provides a higher hardness rating, higher bond strength, smoother surface, and an 80% reduction in hazardous waste. To be able to offer a superior product with eco-friendly attributes is very rewarding.”

HVOF has been proven to increase cylinder and seal life because of its harder, more durable surface. The aircraft industry was among the first to adopt HVOF in its high wear surfaces such as landing gear cylinders, hydraulic actuator rods, turbine engine shafts, and propeller hubs, but many other hydraulic components are now manufactured with HVOF as a standard replacement for hard chrome.

In the HVOF process, oxygen and a fuel gas – hydrogen, propylene, acetylene, or kerosene – are combusted at temperatures of 5000°F to 6000°F. The gases are ejected from a nozzle at supersonic speeds and ignited to form a circular flame.

Then, metal powder such as chrome carbide is injected into the flame and accelerated to velocities over 7000 ft./sec. The metal powder softens in the flame and is sprayed on the cylinder rods to form the coating in layers that range from 0.003 to 0.015 in. thick.

The high-density surface results from the high particle velocity that practically embeds the metal particles into the substrate. The process can produce coatings with zero porosity and bond strengths exceeding 12,000 psi. Besides improving corrosion and wear resistance compared to conventional coatings, the HVOF coating also improves hardness, smoothness, and impact resistance.

Independent testing by members of the Hard Chrome Alternatives Team has shown HVOF to yield little or no fatigue debit, in contrast to chrome plating, which causes a significant debit1. In aviation, where the permissible life of many aircraft components is defined by fatigue limits (maximum allowable flight hours) or by repair limits (maximum number of repairs or total thickness of repair), the HVOF process has performed with coatings that achieve 3-5 times the repair life of chrome.1 The part to be coated must have all chrome removed by stripping electrolytically or grinding, and then thoroughly grit blasted. If the surface has been previously HVOF coated, the surface must be ground to remove any

imperfections. Any area not to be coated must be masked off. During the spray process, the cylinder rotates at 300 surface feet per minute and each pass applies an ultra-thin coating of metal (approximately 0.001"). The final surface finish requires use of diamond belts or diamond grinding wheels. It is necessary to both grind and superfinish HVOF coatings, which creates the super smooth surface that extends seal life.

The actual HVOF coating process takes just one to two hours, compared to 24 hours for traditional hard chrome plating, and its by-products are much safer than the hexavalent chrome (a known carcinogen) that is emitted into the air during the chrome plating process. The EPA and OSHA have introduced more stringent regulations to limit hexavalent chrome releases into the environment, increasing the cost and complexity of hard chrome plating in many shops. The HVOF process produces less harmful waste materials and in considerably less volume.

Summary The real benefit of this new HVOF technology is longer cylinder life with lower cost of ownership, faster overhauls, and less-frequent maintenance, resulting in

more revenue-earning uptime. HVOF is especially useful in industries with extreme corrosion and wear environments such as mining, construction, chemical and refinery, agriculture, marine, hydroelectric plants, and pulp and paper mills.

Benefits of High Velocity Oxygen Fuel Coatings include: • Longer cylinder and suspension life • Longer seal life • Improved corrosion barrier • Improved wear resistance • Higher hardness ratings • Smoother sprayed surfaces • Safer work environment

Applied, through its Spencer Fluid Power subsidiary, has made significant investments in training and equipment to ensure associates have the resources to execute successful HVOF procedures. The company utilizes HVOF in a wide range of applications for industrial repairs of cylinders in all sizes and shapes. Spencer Fluid Power also provides engineering design, systems integration, and fluid power shop services.

Fluid Power Product Spotlight

Hydraulic Hose That Tells You When It’s About to Fail Isn’t Science Fiction Anymore Eaton and Purdue have patented a new hydraulic hose technology, Eaton LifeSense™. LifeSense monitors the health of hydraulic hose assemblies, detects events that have been shown to be symptomatic of the hose beginning to fail, and notifies the user prior to failure with enough time to replace the hose before it fails.

ydraulic hose has a finite life that ultimately ends in failure. Since the cost of failure in terms of unscheduled equipment downtime, environmental spills, equipment damage, and safety can be, and usually is, very high, it is common practice to replace hoses on a regular schedule before they reach the end of their useful lives.

Predictive, or time-based, replacement has been industry practice simply because there was no reliable way to determine the actual condition of a hose while it was in service. Post-mortem examinations of hoses from the field can identify the mechanisms of failure, and these mechanisms have been known for a long time. What has been lacking, however, is a technology to monitor the status of those failure mechanisms while the hose is in service and reliably alert the operator when an end-of-life event is imminent.

Some hose manufacturers have attempted to support this approach with various predictive formulae that consider time, pressure, temperature, the number of flex cycles, and other factors to produce an approximation of expected hose life. This approach causes millions of feet of good hose to be discarded every year, often long before the end of its service life.

Finding A Better Way As a major global supplier of hydraulic hose, Eaton’s Hydraulics Group initiated a research project in partnership with Purdue University to address this issue. Purdue is a member of the Center for Compact and Efficient Fluid Power (CCEFP), an www.ifps.org | www.fluidpowerjournal.com

organization in which Eaton is also heavily involved.

Eaton engineers worked with Purdue researchers and provided access to the Hydraulics Group’s Maumee, Ohio, engineering staff and testing facilities.

The project sought to identify measurable structural phenomena associated with hose deterioration over time and develop the technology required to monitor them accurately. The result, as presented in the abstract of U.S. Patent 7555936 is:

“A system and method for predicting structural failure of a wall of a fluid containment vessel, such as a hydraulic hose or other type of pressurized conduit of types used in mobile machinery, automotive, aerospace, manufacturing, and process equipment. The wall of the vessel has an innermost layer for contact with the fluid contained by the vessel, and an outermost layer parallel with the innermost layer.

The system includes strainsensing means between the innermost and outermost layers and comprising at least one conductor parallel to the innermost layer of the wall.

The system and method entail sensing changes in an electrical property associated with at least one conductor resulting from distortion of the wall of the vessel causing distortion of at least one conductor.”

36

July/August 2011

True Condition Monitoring Eaton has an exclusive license for this technology, which is used in its recently introduced LifeSense hose. The system includes a new hose incorporating at least one conductor in its construction, a special end fitting that serves as both a hydraulic and an electrical connector, and a diagnostic unit containing the monitoring electronics and operator notification interface. The hose is offered initially only in factory assemblies with straight JIC swivel fittings in the widely-used -8, -12 and -16 sizes.

The hose offers performance equal to industry standard EN853 2SN rated hose and, while a unique construction, is certified to the same industry specifications as conventional hydraulic hose products qualified to the 2SN specification.

Additional sizes and fitting configurations are planned for future product line expansions.

The unique construction of both hose and fittings is required to allow the sensing capability.

Although the specifics of construction and monitoring technology are proprietary, the system is based on the fact that certain electrical properties of the hose change as the hose approaches failure.

Comparing periodic samples of these properties to a baseline value gives a highly reliable indicator of imminent hose failure with sufficient warning time for an operator to complete an operation, or in most cases a shift, before the equipment needs to be shut down for hose replacement.

The diagnostic unit contains the electronics necessary to implement the sampling schedule and store enough data to support the necessary comparisons, a proprietary algorithm to detect the relevant changes, and a simple LED output to notify the operator of hose condition. In the initial product offering, the diagnostic unit is hardwired to the fittings on the hose assembly.

One diagnostic unit can monitor inputs from up to 11 hose assemblies.

Bottom Line Benefits During the laboratory testing phase of the hose development, it was discovered that most of the hoses replaced on a time-based schedule of estimated useful life had actually reached less than half of their safe useful lives in the test protocol. In other words, the ability to detect imminent failure accurately can extend the useful service life of these hoses by over 50% on average.

Extrapolating that number to the millions of feet of hose being replaced on-schedule today indicates a significant savings for end users of all kinds of hydraulic systems. Of course, not every hose that is replaced on-schedule is a candidate for the technology at this point, but the potential for cost reduction is significant across the industry.

The amount of downtime required for hose replacement is also an important factor in operating cost. The LifeSense technology can significantly

By Sc o Eaton tt Smith, Se Hydr aulic nior Engi s nee

r,

reduce unscheduled downtime related to hose failure, saving anywhere from hundreds of dollars per hour on construction equipment to hundreds of thousands of dollars per day on an offshore drilling or production platform.

Another major financial impact of technology will be a significant reduction in the number of hydraulic fluid spills caused by hose failure. Laboratory and field testing shows conclusively that a LifeSense hose provides sufficient warning of imminent failure to make spills from that source a very rare occurrence.

Hoses will continue to be improperly applied and compromised by mechanical damage from external sources, as in the case of a hose being snagged by a

www.ifps.org | www.fluidpowerjournal.com

tree limb and ripped off of a piece of forestry equipment. So the technology will not prevent all spills.

But it clearly can dramatically reduce the number of normal hose failures.

The hose has the ability to monitor itself, detect unhealthy symptoms, and warn the user of imminent failure. As the technology behind it expands and matures, it really is possible to envision a time when hydraulic hose failures will no longer be a major concern for equipment operators.

FPDA and ISD WILL “TAKE CHARGE OF CHANGE” AT 2ND JOINT INDUSTRY SUMMIT SEPTEMBER 6-9, 2011 • THE FAIRMONT SCOTTSDALE PRINCESS, SCOTTSDALE, ARIZONA

Developed for fluid power, motion control, automation, and sealing professionals, the FPDA/ISD Joint Industry Summit will bring together members of the FPDA Motion & Control Network and International Sealing Distribution Association who will learn to “take charge of change” September 6-9 at the Fairmont Scottsdale Princess in Scottsdale, Ariz.

The industry has certainly seen highs and lows, but the past few years have proven that those who survive and thrive embrace and implement change rapidly and efficiently. The 2011 FPDA-ISD Joint Industry Summit will focus on taking charge of change with a program built to give attendees proven tips for change that provides a greater path to profits and efficient operations.

Learn about what’s happening in purchasing and how it relates to your sales efforts; explore the shifts in workplace demographics and learn what you can do to prepare for the emerging workforce; delve into selling solutions and how to effectively measure value; and in the latest industry news and trends while networking with industry colleagues.

The opening session, “Managing the Forces of Change,” will focus on the changing Industrial markets. More sourcing organizations than ever before are looking for suppliers that go beyond just providing product. They want suppliers that provide innovative solutions for meeting their organizational goals and who help create a true competitive advantage.

Tim Underhill of Underhill & Associates will look at research from both sides of the supply chain: purchasing and sales. The purpose is to better understand the direction in which the supply chain is headed in order to gain insights into how you can position your organization to take advantage of these changes.

Back by popular demand, the University of Industrial Distribution-in-a-Day will feature four sessions: Creating a Competitive Distinction and Measuring and Reporting Savings featuring Tim Underhill and Preparing for 2020: The Manager's Guide to Dealing with the New Workforce and Business Innovation: Using Creativity and Change to Improve Business Performance by Kathy Newton, Ph.D., Professor of Industrial Distribution, Purdue University.

A unique program awaits delegates at the closing session. “Face Reading” is a tool that gives you an immediate advantage in every face-to-face interaction you have, and it works with every person on the planet.

Mac Fulfer, an attorney who specializes in face reading, will help attendees understand how face reading works, witness a demonstration, and then learn how to begin reading faces. Participants will leave with a tool that will change the way they look at every person they meet.

In addition to this in-depth program, a supplier showcase reception will allow manufacturers to spotlight products and services in a relaxed, casual atmosphere. A wide variety of networking activities have been designed to create multiple opportunities to interact with marketing partners. To learn more about this meeting, visit the FPDA Web site at www.fpda.org.

FPDA is comprised of nearly 250 wholesale distributors and manufacturers of fluid power and motion technology products, as well as product and service vendors to the fluid power distribution services industry. For more information on FPDA, its members and activities, please visit www.fpda.org.

In October 1991, at a meeting of the Buffett Group, Warren Buffett’s inner circle, Bill Gates was asked what he thought of Kodak as a company.

Gates replied: “Kodak is toast.”

As Buffett’s biographer explains, “Nobody else in the Buffett Group knew that digital technology would make film cameras toast. In 1991, even Kodak didn’t know that it was toast.”1 In January 2004, Kodak stopped making most film cameras for developed markets and in June 2009 ceased production of their famous Kodachrome film.

Gates was indeed prescient in this.

As Andy Grove, the founder of Intel is famous for saying, “Only the paranoid survive.” Perhaps Kodak wasn’t paranoid enough to see what was coming.

It is in this context that those of us involved in the fluid power industry probably should be concerned about the threat posed by electromechanical alternatives in traditional, industrial fluid power applications.

There are a lot of applications in which hydraulics and pneumatics have a monopoly on. But they’re not the ones we need to worry about. If it’s a dynamic, growth industry we want, then it’s the applications for which there is viable competition that must be defended.

This is especially true when biases such as “getting rid of the oil” (and the leaks that usually go with it) and eliminating the need for in-house hydraulics expertise (which can be hard to find and retain) influence end-users’ buying decisions.

That said, oil (and air) leaks, and finding and retaining relevant expertise do impact Life of Machine Ownership Cost (LOMOC). And it’s LOMOC that should be the definitive guide for the end user when choosing between competing motion control solutions.

The main components of LOMOC are 1. Initial capital outlay, 2. Energy costs over the life of the machine, and 3. Reliability – the cost of keeping the machine up and running, and losses incurred when it isn’t.

In industrial applications, fluid power has an inherent disadvantage with respect to energy costs (efficiency) and reliability—this is particularly the case with hydraulics.

Let’s consider the efficiency issue first. In industrial applications where mains electricity is the energy source, both hydraulics and pneumatics have to pay a conversion penalty. This is best illustrated by comparing an electro-mechanical, linear actuator to a hydraulic cylinder.

July/August 2011

By Brendan Casey

Fluid Power’s Uncertain Future The block diagrams shown in Fig. 1 depict the components involved in the power transmission process from mains electricity in, to force/motion out, and their typical efficiencies. The efficiency values shown can vary, but the main point is there are more components required in the fluid power solution and therefore more losses.

In the diagrams, the electro-mechanical actuator has a nominal efficiency of 80% and the hydraulic solution, 75%. But an electro-mechanical, linear actuator can have an efficiency of around 80% with a positional accuracy of within 5 microns. For a hydraulic cylinder to approach this level of positional accuracy, a closed-loop, electro-hydraulic control system is required—the efficiency of which is likely to be a lot lower than 75% and could even be less than 50%!

So the electro-mechanical solution is simpler, more energy-efficient and in applications where the system’s operating parameters don’t exceed the current capabilities of linear actuators, you have to admit, it’s very appealing. And that’s without considering maintenance and reliability. There’s no oil leaks to worry about, no filters to change, no oil samples to take, and no blown hoses to replace.

The reality is, compared with most electromechanical devices, even a simple hydraulic system is a lot more complex maintenance-wise and therefore

more difficult to effectively maintain. Furthermore, the achievement of optimal maintenance and reliability outcomes is all too often compromised at the outset through bad or cheap design.

Oil quality, tank size, filtration, installed cooling capacity, conductor size, and connector type are just a few of the corners that are all too easy to cut at the design stage. And while the end-user’s initial capital outlay may be lower as a result, they will likely pay handsomely for this upfront discount over the life of the machine.

Even a relatively well designed (from a maintenance and reliability perspective) hydraulic machine will suffer from reliability issues if left to its own devices over time. This means optimal maintenance and reliability outcomes require a certain level of knowledge (and intervention) on the part of the end user. Unfortunately, this knowledge is often lacking—not only on the part of the end user, but the equipment manufacturer as well.

The result can be a hydraulic system that, perhaps quite rightly, is seen as unreliable, messy, and expensive to operate. When an end user has this type of experience, it’s not surprising that an aversion to hydraulics gets etched into their corporate memory.

In this context, every fluid power system installed is an ambassador for the technology. If it turns out to be a lemon, it reflects badly on the entire industry, www.fluidpowerjournal.com | www.ifps.org

and lingering biases in the mind of the end-user can make a fluid power solution a harder or even impossible sell in the future.

So as an industry, what are our options? There are two that come to mind: 1. Keep doing what we’re doing and ultimately be satisfied serving only those applications in which there is no viable alternative for hydraulic or pneumatic solutions. And concede this slice of the pie may become smaller over time.

2. Wake up and start designing and building fluid power systems for maximum efficiency (in so far as this is possible) AND reliability—in order to

Figure 1

If we choose the proactive option, #2, the first step is to understand and acknowledge fluid power’s weaknesses vis a vis competing technologies; that in many industrial applications we start behind the eight ball when it comes to energy efficiency, and hydraulic solutions in particular are inherently disadvantaged by their real (and per-

ceived) maintenance burden.

The next step is education. Not only must fluid power designers know how to design systems for maximum efficiency; they must also know how to design them for maximum reliability. And it’s the latter that presents the greater challenge—on two fronts.

Firstly, because the majority of fluid power education available today focuses on how it works (or how it’s supposed to work) rather than how and why it fails.

And secondly, designing for maximum reliability and minimum, initial capital outlay are incongruent. A change in industry culture from designing to price, to designing for optimum reliability and therefore mini-

mum LOMOC, will be difficult, if not impossible, in a competitive marketplace driven by a race to the bottom mentality—unless the end user too becomes better educated and therefore more sophisticated in their equipment purchasing decisions.

In other words, the end user must be educated to think in terms of LOMOC for this shift towards the design and manufacture of better performing, and therefore more competitive, fluid power systems to occur.

If as an industry we choose to take up this challenge, it will be no cake walk, that’s for sure. Inaction though, by default, leaves open a “Kodak” scenario: it makes our industry increasingly vulnerable to tectonic shifts in technology.

The Swivel Fittings alleviate the problem of tube alignment and rotation commonly found when using fixed barb fittings. The unique design, Patent # 4,496,204, allows for 360° rotation of the barb and incorporates captured double o-ring seals to prevent leakage. Black nylon or clear polypropylene fittings are offered. Four o-ring compounds are available: Buna-N, Ethylene Propylene, Silicone, and Viton.

Yuken’s “YF Pack” is a compact hydraulic power unit with a piston pump, electric motor, cooler and reservoir. Directly linked modules create a pipeless design eliminating oil leakage. The smaller size and lighter weight of the YF Pack make it easy to build into various machines.

Additional plus: improved cooling capacity, reduced thermal radiation, dual voltage, and noise levels as low as 53dB.
