Quads and the

EEHPC When I first heard the word “quadrillion,” I thought it was a fictitious number like “gazillion” or “bazillion,” but it turns out to be a real number: 1015 or, if you will, a million times a billion. Now, I don’t know about you, but I have a hard time getting my mind around a number that big. I did some calculations that I thought might help: there are 31,536,000 seconds in a year, so a quadrillion seconds would be the number of seconds in nearly 31,709,792 years, which is about 3,171 times longer than the Earth, or even time, has been in existence. This is still nearly impossible to grasp, so I decided to resign myself to the fact that it is just a really big number. Another term with which I am more familiar is “Btu,” which stands for British thermal unit. It represents the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit. When talking about very large amounts of energy, the insiders like to combine the two terms and just call them “Quads,” meaning quadrillions of British thermal units. So, what’s the point? Well, a recent study explored the use of fluid power in the agricultural, mobile, industrial, and aerospace industries. It found that fluid power is one of the leading consumers of energy in North America, using somewhere in the area of 3.1 quadrillion Btu’s (Quads) per year. The same study suggested that fluid power is, on average, only 21% efficient. This is like good news and bad news. The good news is that we are recognized as a leader in the transfer of power and are likely to remain so for the foreseeable future. The bad news is that our systems are inefficient, and we are vulnerable to losing market share to other means of power transfer. I have some more mind-boggling numbers for you to consider: it is estimated that 45-million gallons of water flow over Niagara Falls every minute. The amount of water consumed by fluid power systems in one year is enough to take all the icy water flowing over the falls for 33 days and bring it to the boiling point, an increase of 180°F. The wasted energy is enough to raise the temperature

of that same amount of water 142°F. Given a cost of $.10/kWh, each year about $88 billion is spent powering fluid systems. Of that, about $70 billion is wasted due to inefficiency. Someone responded to this information and suggested that the fluid power industry could make a 5% improvement by simply using “best practices.” If this is true, then we could save about $3.5 billion in energy costs just by doing what we already know how to do and know we should do. It was this information that caused the National Fluid Power Association (NFPA), the Fluid Power Distributors Association (FPDA), and the International Fluid Power Society (IFPS) to join forces and sponsor the first Energy Efficient Hydraulic and Pneumatic Conference (EEHPC) in November 2011. People from all aspects of the fluid power Industry gathered to take a hard look at the way we use energy, as well as ways in which we can improve. I had the privilege of participating in the conference and experienced the enthusiasm of those who attended. We heard discussions on new, efficient fluids; hybrid hydraulic drive systems; tiny hydraulic systems used as prosthetics; ways to improve the efficiency of compressed air systems; and methods

to better store and release fluid energy with minimal waste. The conference revealed that there is much more that needs to be done and that there is a lot of interest from all corners of the industry to get it done. As a result, plans immediately began for a second conference to be held in Chicago, November 27-29, 2012, and it looks like this will be an annual event, at least until we reach an acceptable level of efficiency. In the 2008 Tech Directory issue of the Fluid Power Journal, I wrote an article titled, “Focus on Energy,” where I made this observation: This is what we know: An electro-mechanical system can operate at about 96% overall efficiency. A typical hydraulic system will operate at about 78% overall efficiency. Down at the bottom of the list we find that a typical pneumatic system is about 6% efficient. So, this begs the question: With the price of energy constantly increasing and with the pressure to “go green,” why would anyone in his right mind choose to use fluid power as a means to do work? Those of us who are passionate about fluid power know that there are a number of very good reasons to consider fluid power as a means to do work. There is the concentration of force, the removal of heat, the flexibility, and the ability to produce both linear and rotary motion from a common power source. We can take very heavy objects and repeatedly position them within 0.0005". We can create vacuum that will allow us to pick up delicate and oddly shaped material and safely move it. These are all appropriate things to discuss when presenting the case for fluid power, and many of us have been successful in doing so. I then drew this conclusion: … if fluid power cannot be shown to be an efficient alternative to other forms of power transfer, then we may as well start packing up our formulas and find some other line of work. The frustrating fact is that fluid power does not have to be so inefficient. We are fluid power professionals. That means we are professionals at transferring energy. We need to think of ourselves as energy professionals specializing in fluid power… We need to begin thinking about the entire energy transfer system—from the combustion engine or electric motor to the work being performed. We need to view every kW wasted, every SCFM tossed away, and every Btu removed as an opportunity for improvement. To do less would be a disservice to our profession and to those who depend on our expertise. Many of the problems involving the efficient use of fluid power are of our own making. Because we could do things that no other means of power transfer could do, we thought we were invincible. Energy was relatively inexpensive, so who cared if the air system consumed a lot of extra kW to operate? If our hydraulic power unit needed 7.5 kW to run, we would put on a 10-kW, 15-kW, or even 20-kW motor, just in case. We explained away high system pressure drop as just the cost of doing work or the cost of control. Many distributors stopped

weighing heavily on the minds of everyone, and huge economic issues at stake, we cannot afford to remain idle or complacent. Fluid power can and must continue to be a major player in the transfer of energy that is so necessary for our economic health. We can continually improve our efficiency, sometimes by doing what we already know how to do, and sometimes by creating new products and new approaches to energy transfer.

Even International Fluid Power Society certifications became sales tools rather than badges of achievement and professionalism. Manufacturers still offer pipe thread on their cylinders and pumps knowing full well that it is not good for the industry, the consumer, or the environment. The study cited above is both a great challenge and a great opportunity for the fluid power industry. With competitive means of transferring energy nipping at our heels, environmental concerns

Energy Efficient Hydraulics and Pneumatics Conference November 27-29, 2012 Chicago Marriott O’Hare, Rosemont, IL

Hosted by the International Fluid Power Society (IFPS), the FPDA Motion and Control Network (FPDA), and the National Fluid Power Association (NFPA)

Saving energy and money with fluid power Fluid 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 keeping 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.

The conference will offer: ● Facilitated roundtable discussions, where peers can share specific challenges associated with their industry and applications, and get expert advice from the facilitators. ●

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 educational conference at the Chicago Marriott O’Hare in Rosemont, IL on November 27-29, 2012. Professionals responsible for designing and/or maintaining hydraulic and pneumatic systems in industrial settings or mobile applications should plan to attend.

Breakthrough presentations from fluid power component manufacturers, distributors, and system integrators, showcasing innovative approaches and emerging technologies in energy efficient fluid power design and maintenance. Workshops designed to communicate the current best practices for maximizing energy efficiency and balancing cost issues for hydraulic and pneumatic systems. A full-day seminar on November 27, the Fundamentals of Compressed Air Systems. This hands-on training session, conducted by the Compressed Air Challenge, will show participants how to calculate and reduce the costs of compressed air in their industrial facilities and how to gain better control of compressed air for optimum reliability and productivity. Networking events to help participating engineers and technicians engage with technology providers from fluid power manufacturing and distribution companies.

Students Use Fluid Power for Irrigation at Purdue Competition

D

id you know that you can use fluid power to water plants? That’s what 195 high school students from 10 schools discovered at the Boiler Tech Challenge on April 20, 2012. The theme for the event was agriculture, and it was held at the Purdue College of Technology in Columbus, Indiana. The 2012 competition, Boiler Acres, was made up of six parts: Dig It, Harvest It, Irrigate It, Preserve It, Track It, and Know It. During the Irrigate It challenge, competing teams designed and built fluid power irrigation systems that could draw water from a source and deliver it to plants on multiple levels. “Besides tubing, wood, and syringes, we also provided ‘Y-connectors’ and one-way check valves, though we didn’t tell them specifically what the check valves were or how they worked, leaving them to experiment to learn the function,” said Joe Fuehne, director and Maha associate professor, mechanical engineering technology, at Purdue. “One of the things we learned is that at some point, the delivery water had to be divided several times by the ‘Y-connectors’ to water six different plants. If teams waited too long to do this, there wasn’t enough pressure left to water the plants that were the farthest distance away. It was quite fun.” NFPA continues to bring learning opportunities to students before they enter college. Next school year, middle school students will continue to learn about hydraulics and pneumatics at the Fluid Power Challenge.

Vacuum Valves The most common form of vacuum generation is a vacuum venturi, often referred to as a “vacuum pump.” This can be misleading because a vacuum venturi utilizes compressed air as the motive power, whereas a pump is connected to an electric motor or other rotary power source. Some manufacturers create confusion by referring to their vacuum venturi as a pump. The control of a vacuum venturi is administered by a compressed air control valve. This method of turning the venturi on and off in fast-cycle applications offers certain challenges. Each time the venturi is turned off, the interconnecting hose and tubing between the venturi and vacuum cup is completely discharged of vacuum to allow the cup to release the load being handled. Depending on this distance, the dwell in vacuum release (reintroduction of atmospheric pressure) could be extensive. This is illustrated in Fig. 1. The closer the venturi is to the vacuum cup, the quicker the venturi will create a usable vacuum and when turned off, the faster the vacuum system is “exhausted.” The atmospheric air pressure is reintroduced to the cup via the exhaust of the venturi; therefore, on machinery that requires a very fast pickup and release, the venturi needs to be as close to the vacuum cup(s) as possible. This requirement in a lot of applications has various possible disadvantages to the user: • The filtration required to prevent dirt from entering the venturi takes up considerable space on the end of the tool between the cup and venturi. Some venturi models have integral filtration, but in a lot of cases, this is inadequate due to a small surface area and difficult user inspection and maintenance. More often than not, filtration is ignored, which could lead to considerable cost in ongoing venturi replacement as the nozzle(s) get blocked or even damaged by induced debris. • Because of the need to “ramp up” the vacuum level at the start of each vacuum cycle, the machinery is often programmed to have the venturi ON during the approach to the part to be handled. This uses more compressed air than is necessary, but is also problematic when the cup is approaching dirty or dust-covered parts where the venturi acts like a vacuum cleaner “sucking up” loose debris before the cup seals. • In applications such as steel stamping, the venturi is continuously running during the vacuum cycle, and the oil film, which is present on steel plates particularly in automotive stamping, is atomized through the exhaust of the venturi and dispersed into the working environment. This could be a health and safety concern in the worst case and a machine-cleaning requirement at the very least. • In multiple vacuum-cup applications, considerable compressed air is consumed where a ven-

20

September/October 2012

turi is placed directly on numerous individual vacuum cups. A possible solution to this is the use of vacuum valves, and if correctly selected and installed, this can offer considerable advantages in cycle-rate reduction and the removal of the aforementioned problem areas. A vacuum valve does not necessarily have to replace each vacuum venturi as previously described. In fact, if used correctly, one vacuum valve could be used in place of many single point-of-use venturi. Fig. 2 is a basic schematic showing eight vacuum cups, each using a point-of-use venturi. Fig. 3 shows the same cup layout, but utilizes vacuum-control valves. The difference between these two circuits is simple: Fig. 2 uses a central compressed air supply, whereas Fig. 3 uses a common vacuum supply. The benefit of Fig. 3 over Fig. 2 is that the interconnecting lines between the vacuum venturi and the vacuum valve(s) is always fully CHARGED. (Note the direction of the arrows on the vacuum valve schematic compared with traditional pneumatic valves.) When the cups are sealed against the load being handled, the vacuum valves are turned ON, and if the distance between the valve(s) and cups(s)

⁄⁄⁄

is short, instant grab is achieved. This volume in the tubing between the venturi and the valves vs. the valve and the cups should ideally be at a ratio of about 10:1. For example, if the tubing between the valve(s) and cup(s) is 0.03l (1 fl. oz.), and the volume between the venturi and valve(s) is 0.3l (10 fl. oz.), the following system balance would apply. If the vacuum level is 27"Hg between the venturi/ valve, when the valve opens, the complete system will balance to about 24.5"Hg (0.3/0.33 x 27) as the nowlarger volume of 1.03 L (11 fl. oz.) equalizes. Therefore, the cups immediately grab to a usable vacuum level, allowing the machine to proceed in its cycle virtually instantaneously. Compare this to the circuit in Fig. 1. No matter what venturi the machine builder has chosen, it will have a “time to evacuate a volume” value associated with it. During the initial ON time, the venturi has to get from zero to a usable vacuum level to enable the cups to grip the load being handled. The closer the venturi, the shorter this time will be. But as previously explained, this offers particular problems in filtration, oil or liquid atomization, and so on. The benefit of using the vacuum

valves as shown in Fig. 3 is that proper filtration can be used between the venturi and vacuum valves without affecting cycle time. Also, the venturi can utilize an energy-saving circuit where the venturi will automatically turn OFF when it reaches a preset vacuum level. Due to the single venturi being used with suitable filtration, oil atomization will also be prevented in, for example, a steel-stamping application. Vacuum valves are designed for use with vacuum, and pneumatic valves are designed to be used with compressed air. The valves shown in Fig. 2 can rarely be used for both. Vacuum flow requires large orifices compared with compressed air to prevent flow restriction. The valve shown in Fig. 4 is a direct-acting valve

⁄⁄

Fig. 3

similar to the ones used in Fig. 3. These valves have very large orifices to minimize flow restriction, but because of this, they require a powerful coil of some 10 W. Other valves are available that use pneumatic power as the motive force (pilot-operated), as shown in Fig. 6. This type is also available with solenoid actuation (but pilot-assisted), utilizing a lower power coil less than 5 W in most cases but also requiring a pneumatic power-source connection. Other types of valves are available, but 3-port, 2-position valves are all that are normally required. One condition is vacuum ON (valve open) and the other position is vacuum OFF (valve closed) with vacuum release. Many applications require fast cycle

times and minimal compressed air use. Using vacuum valves, depending on the application, could be a solution for both.

Troubleshooting: Science or Black Art? Y

The increasing complexity of today’s hydraulic equipment means there is a lot to know about proactive maintenance to achieve optimum reliability. It’s my observation that this increasingly specialized knowledge is grossly undervalued in the marketplace. And despite my loud and regular protests to the contrary, the “Holy Grail” of all skills in hydraulics is and always has been one thing: fault-finding.

By Brendan Casey, HydraulicSupermarket.com

up, whether you and I like it or not, the hot-shot troubleshooter—the man who can cast his eye over a hydraulic system and quickly zero-in on the fault without breaking a sweat—is the “Top Gun” in the hydraulics world. He is a soldier of fortune. Admired by some; envied by many.

Troubleshooting expertise is a valuable and sought-after skill, so why are there so many millwrights, mechanics, technicians, and engineers out there equipped with nothing more than a trial-anderror, hit-and-miss, pluck-and-chuck approach to troubleshooting? In the beginning of last year, one of my Hydraulics Pro Club members engaged me in a conversation about the skill of troubleshooting (it is a skill

on its own). And to cut a long story short, his view was that most mechanics, technicians, etc., would never become competent troubleshooters, no matter how much effort is put into them, because they lack the necessary talent. In other words, he was suggesting that troubleshooting cannot be taught, or if it can, it can only be taught to those candidates with the right aptitude.

that troubleshooting ability is some kind of black art that can only be mastered by those gifted with special powers. It’s a view I’d come across before, but since it wasn’t an issue I’d stopped and given a lot of thought to, I went away and pondered it at length. After spending some time considering my own experience and that of the many technicians I’ve worked with, supervised, and trained over the years, I came to the conclusion that troubleshooting is not any kind of black art at all. It is indeed a learned skill. And if something can be learned, it can be taught. Furthermore, I concluded that learning how to effectively troubleshoot is not like learning math where you need mathematical aptitude or learning music where you need musical talent. In other words, I’m convinced that no mystical powers are required to become an expert troubleshooter. Troubleshooting is a skill anyone can learn—anyone who wants to learn, that is. But what does it mean to be an expert troubleshooter? Contrary to what many believe, it has almost nothing to do with the ability to read a hydraulic schematic. While the ability to read schematics is usually helpful in a hydraulic troubleshooting situation, it’s a secondary skill. I’ve been able to read a schematic for 20 years or more, but it hasn’t stopped me from making more than a few troubleshooting mistakes during that time. And when I’m troubleshooting something other than a hydraulic system, the ability to read a schematic is of no help to me at all. This is why the troubleshooting process and procedures I teach in my new troubleshooting training can be applied effectively to any system—not just a hydraulic system—because troubleshooting is troubleshooting. For example, last year my wife started to feel ill after meals. She hadn’t long recovered from an illness that required surgery, so she wasn’t at all keen to start seeing doctors again. As a result, she was putting up with the discomfort. I started paying attention to exactly what we ate at meals and how she felt afterward. After a couple of days of careful observation, it occurred to me that she could have developed gluten intolerance. I shared my observation with my wife, and she agreed to eliminate all wheat products from her diet as a test. The result was as immediate as it was remarkable. Fifteen months later, she still hasn’t been medically diagnosed as gluten intolerant, but it’s hardly necessary because if she inadvertently eats anything containing even a trace of gluten, it makes her feel sick. Clearly, I’m not a doctor, but the process I went through to troubleshoot my wife’s condition is the same process I use when troubleshooting a hydraulic system. Note that my ability to read a schematic was not the key; my understanding of the troubleshooting PROCESS was. And while on the subject of doctors, if you need further evidence that system knowledge in and of

HydraulicSupermarket.com and the

itself is not the key to effective troubleshooting, consider this: The vast majority of doctors are highly qualified, and yet hardly a day goes by when you don’t read or hear about a misdiagnosis that had serious or even fatal consequences for the patient. Doctors use the term “misdiagnosis”; I call it what it is: a troubleshooting mistake. Fortunately, unlike doctors, we in the hydraulics business don’t bury our troubleshooting mistakes, but there’s plenty of room for improvement.

ydraulic fluids flow through the filter in a spiral pattern that improves flow, increases absorption capacity, keeps the filter cleaner, and protects hard-working industrial and mobile equipment from contamination. Keeping hydraulic fluids clean and free from contaminants is an ongoing challenge with industrial and mobile hydraulic equipment, and that challenge has only increased as new types of fluids are introduced and more is demanded from high-tech hydraulic systems. Greater demands for precision, positional accuracy, repeatability, and durability have led to more sophisticated and specialty-engineered hydraulic components, such as high-performance valves. Today’s industrial applications demand tighter tolerances, as well. These developments have had an unwanted side effect: the more sophisticated the hydraulic component, the more damage that dirt and other contaminants can do. Designers have responded over the years by steadily increasing the sensitivity of filters, and as a result, micron-level filtration is not uncommon today. The science of dealing with filtration issues in actual hydraulic applications, however, has tended to remain rather low-tech: wait until the filter gets clogged, then clean or replace it. All filters eventually become saturated with contaminants and need to be replaced or serviced before reduced fluid flow compromises hydraulic performance. So when and how often should maintenance be done? Often, the first sign of a problem is a sudden drop in hydraulic efficiency, which often results in a shutdown until the filter is replaced or cleaned. In some hydraulic applications, a system of regularly scheduled maintenance is used, but this can be inefficient if the system is shut down or filters replaced when there’s no need to do so. Filter clogging rates do not generally conform to a user’s schedule, either, so sudden drops in machine performance can’t always be avoided. Bypass check valves can keep hydraulics operating

longer as dirt accumulates, but they have potential drawbacks. The bypass line can turn into a backflow channel if hydraulic fluid pressure drops below certain levels, allowing contaminated fluid to recirculate through the system and cause damage. The likelihood of this occurring is increased by the fact that once contaminants begin accumulating at a given spot on a filter, they attract even more contaminants at that spot, causing sudden clog forming and pressure drop.

But what if that phenomenon could be avoided by a system that spread the particles out more evenly and directed the larger, heavier ones away from the filter while the fluid flowed through? That type of system, inspired by the swirling motion of the natural force called a “cyclone,” has been introduced to the hydraulic world through Bosch Rexroth’s new 110 LE(N) “cyclone” filter series. The filter head for this series of products is

Fig. 1: The filter head is designed to move hydraulic media and particles in a spiral motion that enhances flow and increases absorption.

Fig. 2: The filter bowl design improves filter element mounting and stability, and helps to ensure constant pressure distribution.

Fig. 3: The mechanical/electronic contamination indicator gives operators advance warning when filter maintenance will soon need to be performed without opening the hydraulic line.

designed to force the incoming fluid to veer off at an angle alongside the filter instead of flowing directly through the filter element. The hydraulic fluid deflects off a protective sleeve and flows in a spiral pattern around the filter materials (mesh, fleece, etc.) as it moves down toward the filter bowl. This ensures that heavy dirt particles are transported to the outside away from the filter pores. Contamination residue is more likely to accumulate in the indentations of the filter bowl rather than in the filter itself. This residue is then simply removed from the bowl. The new design results in a filter that is not only more efficient (thanks to the hydrodynamic effects of the cyclone pattern), but is also more durable. A pressure spring in the filter orients the filter element to the grooves in the filter bowl bottom and protects the filter element from uncontrolled movements due to flow and vibration. The filter bowl bottom’s design helps to evenly distribute the pressure and prevents overburdening the filter in demanding applications. The useful life between maintenance can be greatly extended compared with standard filters because the cyclone filter takes longer to become saturated. Of course, sooner or later, the 110 LE(N), like all filters, will eventually become saturated with contaminants and need servicing or replacement. That’s where another key feature, an electrical early-warning indicator, comes in. A yellow light comes on and sends a signal to the control. The indicator tells the maintenance personnel that the element is at 75% capacity and replacement should be scheduled. At 100% capacity, the red light indicates it is time to replace the element. In addition, a spring-mounted red pin automatically pops up from the filter head when fluid pressure drop is above a certain set point, also indicating that the filter has reached critical-operating condition. This reduces the time, effort, and expense of maintenance. In some applications, a mechanical indicator may be less than optimal because the filter may be difficult to see. That’s why there’s a second option: an electronic indicator that can be fastened on top of the mechanical indicator and provides color signaling to indicate the filter’s condition. Just like a traffic light, a green light (“go”) means the filter is less than 75% saturated; a yellow light means the filter is at 75% capacity; and a red light (“stop”) means the filter is 100% saturated.

The filter element itself also adds to reliability and decreases maintenance concerns. It features six layers of asymmetrically arranged inorganic glass fiber media. The combination of filter layers achieves high efficiency and dirt-holding capacity while keeping pressure loss to a minimum. The filter material is star pleated, positioned around an internal cylindrical support tube, and wrapped in a protective sleeve made from perforated plastic film. This protects the filter against mechanical damage and ensures that the hydraulic fluid evenly flows to the entire filter area.

The filter can be cleaned without replacement via the filter bowl detents, which collect larger particles at the bottom of the filter bowl, and when replacement becomes necessary, it can be accomplished before the accumulation of particles impacts performance. The installation of an electronic monitoring system is relatively simple and protects hydraulic performance without the need for a bypass check valve.

Lower the Pressure to Keep Your

Compressed Air System

Healthy By Bill Scales and Ron Marshall, Compressed Air Challenge

Just as lowering blood pressure reduces stress on your heart, lowering your compressed air pressure reduces stress on the heart of your plant, the air compressor. Manufacturing processes require adequate compressed air pressure to properly function. To avoid problems, production personnel who often believe that “more is better” will increase the pressure, but elevating pressures to higher levels than required increases input power consumed by the motor driving the compressor. In addition to this, the higher pressure causes higher compressed air flow consumed by unregulated air demands, such as air leaks, and thus further increases energy and other associated costs. Training at the Compressed Air Challenge (CAC) has addressed some air system problems, such as excessive pressure drop, that force plant air pressure to be maintained at a higher than necessary pressure. “Pressure drop” is a term used to characterize the reduction in air pressure from the compressor discharge to the actual point of use. Pressure drop occurs as the compressed air travels through the restrictions 26

September/October 2012

within the treatment and distribution system. A healthy and properly designed system should have a pressure loss of less than 10% measured from the final compressor room receiver tank to the point of use. Rule of Thumb for Excess PSI

Excessive pressure drop will result in poor system performance and excessive energy consumption. Flow restrictions caused by any component require higher operating pressures than are needed, resulting in higher input power and energy consumption. Minimizing pressure differentials in all parts of the system is an important part of improving the efficiency of a system. Higher compressor discharge pressure in rotary screw compressors will increase the input power to the motor by approximately 1% for each 2 psi of added pressure in a 100-psig system. A pressure drop in the distribution system and in hoses, tubing, quick couplers, and flexible connections at end-use equipment usually results in lower operating pressure and poor performance at critical points of use. Instead of increasing the compressor discharge pressure to overcome the pressure drop, a more effective

and efficient method is to reduce the pressure drops in the system and thereby improve point-of-use performance. This solution may cost a few hundred dollars in one-time costs; however, increasing the compressor discharge pressure or adding extra compressor capacity to boost system pressure often results in thousands of dollars in increased energy costs. Artificial Demand

Elevating the entire plant system pressure increases air consumption at locations such as leaks, open blow-

ing, and production applications if they are unregulated (Fig. 1). The added flow of compressed air at elevated pressure is termed “artificial demand” and substantially increases energy consumption. Equipment should be specified and operated at the lowest efficient operating pressure, thus allowing lower system pressures and reduced artificial demand.

What Causes Pressure Drop?

Any type of obstruction or restriction in a system will cause resistance to air flow and cause a pressure drop. In the distribution system, the highest pressure drops are usually found at the points of use at the end of the compressed air system, including undersized hoses, tubing, quick-disconnect couplers, and filters, regulators, and lubricators (FRLs). On the supply side of the system, main-line dryers and filters can be significant causes of pressure drops (Fig. 2).

70psig

Regulated End-Uses

Plan for Peak Flows

The maximum pressure drop between the supply side and the points of use will occur when the compressed air flow rate is highest. System components should be selected based upon these peak conditions, not average, and the manufacturer of each component should be requested to supply pressure drop information under these conditions. When selecting filters, remember that they will get dirty. Dirt-loading characteristics are also important selection criteria in maintaining adequate pressure over the long term. Large end-users that purchase substantial quantities of components should work with their suppliers to ensure that products meet the desired specifications for differential pressure. Measure the System

The distribution piping system often is diagnosed as having a high pressure drop because a poorly selected point-of-use pressure regulator cannot sustain the required downstream pressure. If such a regulator is set at 85 psig, and the regulator and upstream filter have a pressure drop of 20 psi, the system upstream of the filter and regulator would have to maintain at least 105 psig. The 20-psi pressure drop may be blamed on the system piping rather than on the components. In many cases, undersized valves or connections to the end use can also be the cause of excessive pressure drops. The correct diagnosis may require pressure measurements at different points in the system to identify the component(s) causing the high pressure drop. In this case, the size of the filter regulator and/or downstream connections may need to be increased, not the main line piping (Fig. 3). Effects of Reducing Pressure

• Complete Package Solutions! • Global Presence. • Local Expertise.

Reducing and controlling the system pressure downstream of the primary receiver can result in a total system reduction in energy consumption of 10% or more. Reducing system pressure, like lowering your blood pressure, also can have a healthy cascading effect in improving overall system performance. Other benefits include reduced leakage rates, increased system capacity, and increased compressor life. However, a reduced system-operating pressure may require modifications to other components, including pressure regulators, filters, and the size and location of compressed air storage. Lowering average system pressure requires caution since large intermittent increases in demand can cause the pressure at points of use to fall below minimum requirements, which can cause equipment to improperly function. These problems can be avoided with careful matching

of system components, controls, and increased compressed air storage capacity. Specifying Efficient Equipment

For applications using significant amounts of compressed air, it is recommended that equipment be specified to operate at lower pressure levels. The added cost of components, such as larger air cylinders, usually will be quickly recovered from resulting energy savings. Some plants specify end-use equipment to operate at an average system pressure, which can eventually result in higher operating costs. First, the point-of-use installation components, such as filters, pressure regulators, and hoses, will be installed between the system piping and the end-use equipment. Second, leaks will occur and filters also will get dirty, both resulting in lower pressure. This should be anticipated in specifying the available point-of-use pressure. If an individual application requires a higher pressure, instead of raising the operating pressure of the whole system, it may be best to replace or modify this application. It is also important to check if OEM manufacturers are including pressure drops in filters, pressure regulators, and hoses in their pressure requirements for end-use equipment or if the stated pressure requirements are upstream or after those components. A typical pressure differential for a filter, pressure regulator, and hose is 7 psid, but it could be much higher in poorly designed and poorly maintained systems. When demand pressure has been successfully reduced and controlled, attention then should be turned to the compressor control set points to obtain

Fig. 3: Example pressure measurement points (Courtesy of Compressed Air Challenge)

more efficient operation. It may then be possible to unload or shut off a compressor to further reduce energy consumption. Strategies for Minimizing Pressure Drop

Minimizing pressure drop requires a systems approach in design and maintenance of the system. Air-treatment components, such as dryers and filters, should be selected with the lowest possible pressure drop at specified maximum-operating conditions. When installed, the recommended maintenance procedures should be followed and documented. In summary, additional ways to minimize pressure drop are as follows:

• Properly design the distribution system. • Select dryers and filters having the least possible pressure drop for the rated conditions. • Maintain air-filtering and drying equipment. • Specify pressure regulators, lubricators, hoses, quick couplers, and other connections having the best performance characteristics at the lowest pressure differential. Keep the pressure on, but not too much! * Information for this article was obtained from Compressed Air Challenge publications.

Fluid Power Industry

Going

Green By Mark Miller, Terresolve Technologies

E

nsuring responsible use of lubricants to avoid environmental damage is an ongoing responsibility of those who work in the fluid power industry. As fluid power engineers working in a variety of markets look to use more environmentally safe fluids, it is important to understand the benefits and constraints of the various types of biodegradable fluids available. This article will examine differentiators for all readily biodegradable fluids. (Note: Only “readily biodegradable” fluids, which break down quickly when they enter the environment, were considered for this study. “Inherently biodegradable” fluids, which require long-term remediation due to environmental persistence, were not considered.) The following is a summary of the types of readily biodegradable fluids and the results found for each fluid.

Base Fluid Classification There are four main classifications of environmentally preferable fluids as defined by ISO 6743/4: HETG vegetable-based, HEES ester-based, HEPG glycol-based, and HEPR PAO-based.

Conventional Vegetable-Based Fluids (HETG)

Early work in the field focused on lubricants made from vegetable oils (natural esters or HETG). Vegetable-based fluids are readily biodegradable, but their performance is most suited to cool and dry operating conditions. Equipment operators must take care to ensure that such parameter boundaries are not violated. HETG fluids can typically only withstand operating temperatures under 180°F-200°F. As a result, vegetable-based fluids, when exposed to heat, will rapidly oxidize and therefore will have a limited life expectancy. Another issue with the vegetable-based fluids is that they become unstable when exposed to wet environments or contaminated with water. These fluids should be utilized in light-duty

applications with controlled environments and relatively short change-out intervals.

Synthetic Esters (HEES)

The second phase of bio-development focused on synthetic esters (HEES). This classification of fluids is one of the most common synthetic biodegradables in the market. Synthetic esters are readily biodegradable and perform well in standardized oxidation tests, which determine the life of the lubricant under test conditions. When new, clean, cool, and dry, synthetic esters offer excellent performance.

Limitations

Esters are synthesized by the reaction of a triglyceride (typically vegetable oil) with an acid and an alcohol. This reaction makes the ester, and forms water and heat as by-product. Expressed chemically: Vegetable Oil + Alcohol + Acid ↔ Synthetic Ester + Water + Heat

The double-headed arrow indicates that the reaction goes in both directions. Therefore, when water is present, the reverse reaction occurs and is known as “hydrolysis.” This reforms the alcohols, acids, and the triglycerides. In machine service, the acids can

cause rust and wear, seal degradation, and corrosion to yellow metals. Consequently, ester-based fluids must be maintained in a cool, dry state to obtain maximum performance. Because of harsh production environments, synthetic esters may not perform as well in some industrial applications regardless of their biodegradability characteristics.

Poly Glycol (HEPG)

PAG fluids offer a wide range of performances and characteristics, most notably the ability to absorb water and resist flame. These characteristics severely

limit its use in some industrial applications since it draws water into the system, creating rust and wear. From a performance perspective, they are frequently incompatible with conventional materials and need special seals and filters. In addition, they are incompatible with conventional lubricants, and a complete flush is required to change over. If PAGs enter the environment, they will disperse in the water, reducing the ability to clean up the fluids.

PAO-Based Fluids (HEPR)

The remaining classification is the HEPR group. This

classification embodies fluids derived from PAO-base stocks, such as bio-polyolefin. One distinct advantage of PAO-based fluids is that they can be tailor-made to fit specific requirements. These fluids do not hydrolyze (break down when mixed with water), making them very stable in hot, wet conditions. Bio-polyolefins are typically compatible with Buna N, Viton, all common elastomers, and adhesives used in filters. Table 1 shows the various performance characteristics of the different classes of environmental fluids and where each should be utilized. Based on the extensive findings, we can conclude that bio-polyolefin synthetic

Better think again.

Why settle for inferior cleaning methods when even the smallest bits of dirt and grime can end up costing you big in machine failure and downtime? The Ultra Clean System uses a pneumatic launcher and specially formulated projectiles to quickly, cleanly and thoroughly eliminate contaminants -- even those typically left behind after fluid flushing and air blowing. When others’ versions of “clean” just don’t cut it, you need Ultra Clean, the leader in contamination control.

Field Performance Terresolve took these findings into consideration to create readily biodegradable fluids that can serve as direct replacements for synthetic-based and petroleum-based hydraulic fluids. Envirologic 3046 is bio-polyolefin synthetic hydraulic fluid that shows excellent performance with viscosity in specification, low acid number, and little to no wear. In 2002, Terresolve began a long-term field trial with a major offshore drilling contractor. All performance aspects were recorded and logged for over 20,000 hours. The central hydraulic system and auxiliary systems operated over 40 different pieces of equipment from most major manufacturers including National Oilwell Varco, Weatherford, Schlumberger, Ingersoll Rand, and others; it powered five hydraulic power units from Hannon and Rexroth axial-piston variable-stroke pumps. The test found that the fluid and system performed perfectly, showing no wear, oxidation, or breakdown of any kind. The contractor was able to reduce operating costs by over $150,000 per year by reducing downtime from valve sticking and reducing fines. Over the long term, additional savings were recognized because they were able to reduce leakage and extended fluid life to over twelve years, as exhibited in Fig. 1. Since the study, several contractors have expanded the use of biodegradable products throughout their fleets, including cranes, deck machinery, and a variety of pipe-handling equipment.

Investing in Biodegradable Fluids

biodegradable oils perform best in offshore fluid power industry applications, whereas the other three types of fluids are too weak to perform well in these very specific applications.

www.fluidpowerjournal.com | www.ifps.org

Despite the rising cost of petroleum products, biodegradable lubricants cost more than conventional products on a per-gallon basis. The reason for this is they start with more expensive base fluids and utilize more expensive chemistry that will deliver the performance required without reducing environmental benefits. In the long term, the initial investment is small when compared with the cost of fines and cleanup in the case of a spill and the overall environmental impact. In most cases of oil leaks or spills, major fines and clean-up costs can be greatly reduced or eliminated by using readily biodegradable fluids. For example, if a supervisor of an offshore rig can increase overhaul interval time by even one year, a rig can save tens of thousands, if not hundreds of thousands, of dollars. Readily biodegradable lubricants must be properly maintained. Since the key to long fluid life and toptier performance is keeping the fluid clean and dry, proper filtration is essential. As fluid power engineers consider adopting these readily biodegradable fluid solutions, these findings are crucial to observe before making the best choice.

Pressure Effects on Seal Performance By Annie Maloney, Colonial Seal Co.

⁄ ⁄ ⁄⁄ ⁄ ⁄⁄ ⁄ ⁄⁄ ⁄ ⁄ ⁄ ⁄⁄ ⁄ Standard shaft seals or rotary shaft seals are typically found in low-speed or low-pressure environments. As the speed of the shaft increases, the maximum allowable pressure decreases, and as pressure or speed increases, the design of the seal needs to change to ensure the life of the seal.

S

tandard shaft seals are designed for pressures from 0 to 7 psi. Slightly increasing this pressure could result in forcing more of the air side of the seal lip down onto the shaft. As the shaft turns, there is more lip contact on the shaft, which can cause greater lip wear. A conventional seal design with a single spring-loaded NBR lip and metal case has a useful seal life of

2,000 hours with a shaft speed of 1,000 rpm or less. The resultant seal lip wear is approximately 0.025". If the pressure in this environment is increased to greater than 10 psi, the seal lip wear increases by a factor of at least four, and the resultant seal lip life is reduced to less than 20% of the design limits for standard seals. This is a dramatic decrease in seal life with just a slight increase in pressure. There are several other pressure-related factors that affect the life of the seal, such as excessive dirt, debris, or other contaminants. When these are found in or near the seal lip surface, they can cause higher pressures at the seal lip contact point. As a result of these higher pressures, the seal lip life may be adversely affected. Higher pressures could also distort the seal, causing the sealing lip to leave the shaft. This condition is known as “bell mouthing,” resulting in the sealing portion of the lip showing little or no wear, and the air side of the sealing lip showing heavy wear. This greater wear, as expected, also shortens seal life. In extreme, high-pressure scenarios, the seal could be forced out of the bore or even have the rubber-to-metal bond torn. To reduce the effect of slightly higher pressures in a lip seal environment, several alternative designs are available. If your environment is known to have an increased presence of dirt or debris, adding a secondary lip to the seal that will exclude these contaminants should reduce the potential pressure increase and thereby increase the probability that your seal life will attain its desired lifespan. Without changing the design of a standard seal that is operating with a lubricant, increasing the sump level should also reduce the lip contact area when the lip is subject to slightly higher pressures. To meet higher pressures, there are a number of non-standard shaft seals available. These non-standard designs are characterized by shorter lip lengths, increased beam thickness, or heavier cross sections in order to minimize distortion in a higher pressured environment, a greater bonding area between the lip and metal case (unless an all-rubber cover shaft seal is used), and the use of a snap ring or flange to ensure that the seal case is retained in the bore. For applications requiring pressures of 100 psi, a backup ring of Teflon (PTFE) is used. There are also other factors to be considered when designing a shaft seal for higher pressures, so it is recommended that a seal designer ensure that the optimal design is provided for an application.

Don’t Let a Little Leak Turn Into a Catastrophe! Most hydraulic systems operate under extremely high pressure. So leaks can not only lead to equipment breakdown and production delays, but serious personal injury as well. Fortunately, there’s the Spectroline® OPK-341 Leak Detection Kit. It’s the most effective, efficient and safest method for finding leaks in hydraulic and oil-based industrial systems. And best of all, it finds these leaks long before disaster strikes!

INTRODUCING TELESCOPIC CYLINDERS

Complete Line of Equipment

Muncie Power Products //// Circle 418

Oil-Rite Corporation //// Circle 419

Muncie Power Products has once again extended their reach with their new single-acting telescopic cylinders. These uniquely designed cylinders provide performance and value through advanced machining and the use of proprietary seals to deliver extended life without need for adjustment. The cylinders have been engineered with machined hard stops to guarantee reliable stopping at the end of every stroke. The bore size of the final stage is larger but the average displacement of the stages has been reduced. This allows Muncie’s cylinders to require less oil than those of its class and ultimately leads to faster cycle times and the ability to lift more using the same pressure.

A NEW full color 104 page catalog is available on Oil-Rite’s Lubrication Equipment featuring PurgeX ® Centralized Lubrication Systems. Complete “turn key” systems are available for immediate delivery. Liquid or Grease delivery. Air or Electric Motor Operated.

Fluid Power Case Study

Bypass Kidney-Loop Filtration Technology Delivers Huge Dividends By CCECO Oil & Filtration, LLC

Being a “green” company is nothing new to CCECO Oil & Filtration, based in Kent, Wash. A recent push for the company to enlarge its distributor network emphasized its green initiative by providing products that lower maintenance costs, extend equipment life, and reduce stress on the environment. The bypass kidney-loop filtration technology incorporates ultrafine micro filtration of less than 1 micron with dense cellulose membrane media that captures and entraps particulates. Resistant to cyclic flow, the filters outperform most pleated filters that often re-release trapped particles back into oil systems when there is vibration or cyclic oil flow.

When a repair was recently needed on a unit that had CCECO filtration, Barns and his maintenance team were amazed at how clean the inside of the pump was, with virtually no wear. The heavy-duty lid of the “no-spill” system design has an O-ring seal and can be easily removed without tools. In five minutes (or less), the filter can be removed without causing a big mess. “Hydraulic oil is the lifeblood of our equipment, and keeping the oil clean has reduced breakdowns and has doubled the life of our equipment,” said Barns. He is also in the process of installing spin-on Oil Extenders.

INDUSTRY CHALLENGES

In addition to tightening budgets, an answer to rising economic pressure is reducing equipment maintenance and replacement costs. Improving oil cleanliness can add years to equipment life and can significantly reduce repairs. Most equipment manufacturers, plant engineers, maintenance personnel, and industry experts agree that 70-80% of hydraulic and engine-component failure is caused by contamination and moisture. Companies are experiencing increased pressure to monitor waste and document oil-disposal methods. The simple installation and easy maintenance of bypass filtration systems cover a wide range of industries and applications, and provide a way to comply and feel good at the same time. “The good news is that we reduce dependence on foreign oil and reduce waste dumped into landfills,” said Jim Harris, CCECO general manager. The International Standards Organization (ISO) adopted a rating system for oil cleanliness that measures the amount of particulates in a milliliter of oil for 4µ, 6µ, and 14µ particles. Typically, new oil does not mean clean oil, and cleanliness levels range around 22/21/18 (refer to Table 1). This translates to between 20,000 and 40,000 damaging particles circulating in every milliliter of oil. That’s a huge number. Bypass filtration technology can reduce this number to 16/14/12 or better. At 16, the circulating 4µ particles drop to 320-640 per milliliter. Every ISO code number reduction represents 50% fewer particulates. Many new hydraulic components (pumps, servo valves, etc.) require ISO oil cleanliness levels of 17 or less.

INDUSTRY SOLUTIONS Case Study #1 Joe Barns and his team from Gary Merlino Construction were experiencing an elevated level of premature equipment breakdowns, so they installed CCECO Gold and Oil Extender units on many large excavators, paving equipment, and small tractors in their fleet. These units are working on hydraulic reservoirs from 60 gallons to 1,200 gallons.

Case Study #2 Hay press facilities represent another key industry eager to reduce maintenance, repair, and operation (MRO) costs from equipment breakdowns directly attributed to fluid contamination. The staff at ACX Pacific wanted to find a solution to remove contamination in its hydraulic systems, and they worked with CCECO to install filtration units on several of its hay presses. “Hay press facilities can be very dusty environments,” said John Gombos, unit leader for ACX Pacific. “I was a little skeptical at first, but when I saw the oil actually change color from dark brown to light brown, I was thoroughly convinced. We were changing out 2,000-gallon reservoirs every 12-18 months. Now we take our drain intervals out several years with huge savings for our operation.” Fig. 3: Gold GEM300-GH134 unit

Case Study #3 Alaska Marine Lines (AML), a Lynden Company, was looking for ways to increase the utilization and longevity of its capital equipment. Harris helped educate AML personnel and installed several units on key equipment. “CCECO filtration solutions have provided AML with a needed boost in our cost-reduction efforts,” said Les Candee, AML manager of maintenance, equipment, and procurement. He plans to install Oil Extender units on diesel generators and is considering them for the company’s tugs and barges.

THE RESULTS

These companies and many others are seeing the benefits of bypass filtration. The filtration systems are known as “kidney loop,” which

inspired Harris to coin the phrase “oil dialysis” several years ago. Oil-filtration systems operate like their medical counterparts for kidney dialysis by removing fluid, cleaning it, then replacing it into the circulating system. The systems are achieving superior results and seeing ISO cleanliness levels of 14/10/8 or lower. Individual filter elements can last six months or longer with dirt-holding capacities of 5 lbs and water removal of up to one gallon. The popular buzz about carbon footprints is now affecting many industries and government entities. It takes a huge amount of energy to squeeze lubrication oils from crude, and it takes more energy to refine a gallon of lubricating oil than it takes to produce a gallon of gasoline. It is estimated that the process of producing a gallon of lubrication oil (crude oil extraction, transportation, and refining) generates 10.27 kg (22.6 lbs) of CO2. Extending oil-drain intervals and using fine-micron bypass filtration combined with frequent oil sampling and analysis can clearly help organizations reduce their carbon footprints. “It’s very rewarding to hear our customers describe superior results with our filtration equipment in such demanding industries,” said Harris. “It’s a wonderful bonus to know that we are helping them save money and reduce their carbon footprints at the same time.” CCECO Oil & Filtration designs, builds, and sells patented oil-filtration units that filter down to less than 1 micron for mobile or stationary hydraulic systems. The company specializes in filtration of hydraulic oils, engine oils, gear oils, and transmission fluids. For more information, visit www.cceco.net or www.theoilextender.com.
