Notable Words

The Man Who Revolutionized Hydraulics

hat was the greatest invention in our industry? I have spoken to many industry experts over the years, and my conclusion is that the gerotor theory used in hydrostatic steering and low-speed high torque motors changed our industry forever. The theory and products invented can be directly attributed to Lynn (Buck) Charlson, founder of the Char- Lynn Company in 1942 and predecessor to the Eaton Corporation. The basic design principles of these products have not changed over the years and are being used by several manufacturers. Today, these designs represent over $1.2 billion dollars in sales throughout the world. In fact, the markets for these products are still growing faster than industry averages! What do we know about Buck Charlson? He was a high school graduate who worked as a night clerk at a shabby hotel in the 1930s. At the hotel, he met a man who worked for a manufacturing company. The man piqued Buck’s interest in Lynn (Buck) manufacturing, as Buck was studying engineering theory. Charlson (19 09-2004) Shortly thereafter, Buck formulated his own theories and began to develop products that he believed would revolutionize an industry. In 1942, Buck formed the Char-Lynn Company and manufactured many items that were used to win WWII. Following the war, business became very difficult, and creditors were at the door. Fortunately, Buck won a large order from a major OEM manufacturer for an auxiliary pump called the “Hi-Lo Pac.” Buck also had a die cast operation, which helped in manufacturing fluid power products and supplying unique designs to OEMs. CharLynn was saved! Most of the unique gerotor products went into production in the 1950’s. In 1965, Buck had the foresight to build a manufacturing facility in Eden Prairie, Minn. The company grew 45% that year. When I researched his financials, his EBIT averaged over 22% and sales increased five-fold the last eight years Buck owned Char-Lynn. What an exciting time! Interestingly, at that time, the Corporate Tax Rate was 50%. In 1970, Eaton Yale and Towne purchased the Char-Lynn company from Buck. I had the opportunity to do research at Life Science Foundation, located in Victoria, Minn., where Buck had a farm and continued to work and create after selling Char-Lynn. What a trove of information! Here are some interesting things that I discovered about this forward-thinking individual: 1. Buck seemed to see the world in 3D. Without 3D perception, it would have been impossible for him to articulate his unique ideas. (Remember, personal computers weren’t around in the 1940s.) 2. People described him as determined, dedicated, committed, philanthropic, loyal, self-taught, intuitive, a visionary, and a very impatient individual. 3. Words like “can’t” and “never” were not words you wanted to use around Buck. If you did, you were off his “A” list and he would promptly prove you wrong. 4. If he had a unique idea for a product that he could not figure out immediately, he left a small piece of paper on the corner of his desk describing the problem. He looked at the piece of paper every day until he figured out the solution. Nowadays, that’s called “focusing.” 5. When a new gerotor product was patented, he always told salespeople to “get out and sell – the patent is only good for 17 years.” 6. He believed strongly in dual distribution: “Two or more distributors competing with each other is stimulating, healthy, and will continue.” Yes, Buck Charlson was a unique man. From him, our industry learned to expand unique technology to help us develop and produce innovative and competitive products. He believed in encouraging the “A” team and to instill in them a sense of drive and competition. Our industry would not be the same today if it not for Lynn (Buck) Charlson. By David E. Thun, Power Systems

My thanks to Nancy Nelson, president of Life Science Foundation, and Harley Bergren, Power Systems’ founder, and George Beniek, the latter two, former employees of Char-Lynn, for their help in gathering information for this article.

all about Air

Precious Pressure any compressed air systems resemble a bucket full of holes that someone fills and carries back to camp with only half of the water upon arrival. Obviously in that case, the wasted effort and work would be quite noticeable. With compressed air, leaks are costly and should be dealt with. More wasteful and possibly less obvious is pressure drop. A great deal of attention is being paid to reducing leaks in compressed air systems including new devices and techniques, even money from the federal government to fix leaks.

What is being done to reduce or improve the rate of energy lost to pressure drop? It is the precious pressure that provides force to do work. Work is what we pay for to get the job done. An analogy might be driving with one foot on the accelerator and one on the brake. In any event, it is an unnecessary expense and more than a little silly. A compressed air characteristic causes a drastic change between laminar and turbulent flow. Laminar flow exists when the Reynolds number is somewhere less than 3000 and almost always when less than 2000. Laminar flow is resisted only by the almost negligible viscosity of the air. There is very little resistance with laminar flow even in rough and rusty plumbing. With turbulent flow, the air impinges, swirls, and rebounds upon itself and the interior of the plumbing, causing high resistance and pressure drop.

Have you checked your plumbing lately? If an increased air requirement and greater demand has added to the original usage estimates, you are almost assuredly in trouble. Generally conventional wisdom, common practice, planning, and advice on plumbing compressed air systems is atrocious. In one booklet it states, “When installing plumbing for compressed air systems, the greatest cost is labor.” Spend an extra dollar once to double the pipe size to be installed and save hundreds over time. Most charts give tidy (and undersized) flow values for 100 feet of straight, clean pipe. Your plumbing may have multiple sizes, different angles, fittings, etc. between point A and point B, and the distance is whatever was required—not tidy 100foot lengths.

To check it out: 1. Chose point A and if there is no gauge installed there, put one in. 2. Chose point B and install a gauge at that point. Ask an associate to record the average pressure at point A for approximately a minute while you do the same simultaneously at point B. Compare notes and subtract average A from average B to get the approximate pressure drop. If the pressure difference from point A to point B is greater than 2 psig, roll up your sleeves. Pressure drop is inefficient, expensive, counter productive, and almost entirely optional. With pipe sizes at least twice the diameter suggested by common charts or conventional wisdom, you will be happy, wealthy, and wise.

What areas of opportunity in the mobile market segment do you see as growth areas in 2012?

Daub: With the Tier IV final requirements, space is a huge issue. If you can help your OEMs save space and integrate functions in your components or systems, you increase your chances to get specified. Being a filter supplier, we have worked on customized solutions to integrate different functions (cooler bypass valves in tank top or inline return line filters, various check valves, etc.) into our filter heads. The volumes of hydraulic reservoirs also get reduced to a point that the oil doesn’t get enough time to cool down or get an effective deaeration. We have developed test equipment to monitor the deaeration and customized our filters as well as the customers’ reservoirs to improve deaeration. Another big growth potential is on the machines that are developed for low regulation countries (China, India, Brazil, Russia, etc.). The requirements are here more on the coast side. This opens opportunities to suppliers who can offer complete systems integrating various components from their product ranges. A strong presence in these countries is crucial, as well. Harwick: Generally the hydraulics industry in the U.S. will see a very strong year for growth. The age of the average automobile on the streets in the U.S. is 11 years. Historically, the average has been 8 years. There is a massive pent-up demand for new automobiles, and with the slight improvement in the economy, we should see robust auto sales through 2012 and 2013. Hydraulics is used all through the automotive industry and at many of the Tier 1 and 2 suppliers. This strength in auto markets will translate to a stronger economy and more tax revenues spent on always-popular U.S. infrastructure projects. These projects will drive an increased demand for mobile equipment. Mulder: Our primary focus is the mobile hydraulic industry, and our primary off-road targets for 2012 will continue to be construction, agriculture, and utility equipment OEMs. As proven throughout the cycle of an ever-changing economy, these core industry segments continue to yield the most attractive and consistent opportunities. We will also be seeking new opportunities to diversify our strategic position in the hydraulic coupling market. Classified as “non-traditional segments,” these markets parallel the off-highway definition. The clear benefit is critical market expansion with high sales margins. Vasilovski: The areas of growth that I see for the upcoming year are in alternative energy and construction due to infrastructure projects and government funding.

with Tobul, The Pressure Is Always On!

Are there any new products/innovations that you foresee as game changers in the industry?

Daub: Spin-on filters dominate the market today. They are easy to service, but no element change can be done without spilling oil. With every filter change, the customer has to dispose the whole can, including the residual oil, which is not ecological. A clear shift to cartridge-type or filter elements is seen. The requirements to modern hydraulic filters are better filtration efficiency, higher stability, lower recycling costs, lower

Harwick: We are effectively at the end of the shift from hydraulics to electric drives, which the industry has experienced for the last 20 years. The robust and forgivable nature of hydraulic fluid power is well recognized with mobile equipment OEMs. While electric drives have won some applications, the remaining applications need the advantages of “compact” power, flexibility, and reliability provided by hydraulic fluid power systems. Mulder: We are constantly requested to collaborate with the fluid conveyance technical teams of worldwide off-highway equipment manufacturers. This co-engineering agenda has resulted in the evolution of our company’s connect-under-pressure products.

weight and shipping costs, and use of non-metallic hardware for easy incineration. Another clear trend is the use of Group II oils in certain industries, as well as smaller filter element designs. These increase the risk of electrostatic discharges (arcing in the oil, which leads to rapid oil aging, filter element destruction, short circuit of controllers, explosion of air breathers, etc.). One way to avoid this phenomenon is to increase the surface area of the filter element, which is not possible due to space restrictions. We have developed a Stat-free filter element using special filtration layers, which dramatically reduce the electrostatic charges of the oil. I see big potential for this type of technology in the near future.

gaining market share. We handle business now more often on a system (reservoir packages) base as on a component base. Harwick: The general need for improved fuel economy and its natural link to lower total emissions has lead to increasing use of complex pump compensators for more energy-efficient circuits. Even the mainstay double pump â&#x20AC;&#x153;high-lowâ&#x20AC;? circuits used in packing and other mobile applications are shifting to HP limiting and other energy-efficient single pump systems. Mulder: As our core products are not directly related to the emissions initiative, the impact to the

Daub: Space and weight have always been major factors in the design of filters for the mobile industry. With the Tier IV requirements, the engine after treatment devices are taking much more space, so these factors have much bigger importance. Standard components or reservoirs are very difficult or almost impossible to integrate. Plastic reservoirs, which can be designed with very complicated shapes to fill any open space on the mobile equipment are

design and manufacturing of our components has been zero. As a company, however, we have capitalized on the opportunity to further penetrate core equipment markets to application requirements. Recent advances from our Italy-based R&D team have allowed for strategic positioning to compliment key customers and their next-generation platform designs to include connect-under-pressure hydraulic couplers and manifolds. Vasilovski: The Tier 4 standards require that emissions of PM and NOx be further reduced by about 90%. I believe that in the mobile market you may see more control technologies to help with emissions requirements. Moving forward, if you could predict the future, how do you think the mobile market will perform in terms of sales for the rest of 2012? What reasons give you confidence (or pessimism) for the future?

Daub: In the United States, the growth should still be significant mainly due to emerging markets. The major large OEMs have plans to export in these regions and most of the machines are still being manufactured in the U.S. for now. To be a hydraulic supplier and a large player in the mobile market, it is necessarily to have a complete hydraulic product range and to be a global partner (worldwide presence and high level of local competency). Harwick: The manufacturing and sourcing efficiencies gained by U.S. OEMs during the difficult periods of 2010 and 2011 have left the U.S. with a stronger, more internationally competitive manufacturing structure for mobile equipment. This combined with a weak dollar (vs. traditional levels) will allow U.S. companies to gain export business outside the U.S. Many countries around the world are growing and improving their internal transportation infrastructures. All these projects will be consumers of U.S. branded and built mobile equipment. Our stronger OEMs with a world focus will lead U.S. fluid power to a very strong year. Mulder: As with many technology-based companies, analyzing industry trends is important to our overall business strategy. For our technology, there are three core markets: agriculture and construction equipment manufacturers and industrial. Generally speaking, the AG market is fairly consistent as the primary driver in the global demand for food. Certainly, bio-fuels and individual crop yields are considered, but the increasing global population and evolution of traditionally low-cost countries are what really contribute to AG equipment trends. Construction equipment demand, at least relative to our core technology, is measured by housing/commercial facility starts and infrastructure expansion. We have realized a significant uptick in this area for which the trend seems to be consistent global growth for the last several months. Vasilovski: The U.S. is the largest regional market for hydraulic equipment in the world.Â I believe the mobile market will continue to grow at an annual rate of 4% to 6%. Growing concerns over the environment can open up new markets for mobile fluid power such as biodegradable fluids and demands in infrastructure.

Demonstration of Energy Efficiency Benefits Using Laboratory Tests

Engineers and end-users who are looking to improve the efficiency of their mobile hydraulic plants through a change in hydraulic fluid are faced with data from a wide variety of tests that can range from a basic fluid property through to field trials. A convenient way to assess the value of an energy efficiency claim for a product is to categorize the test used in terms of its relevance to real-world operation and its ability to demonstrate a true improvement. This latter feature is normally a measured difference in performance between two hydraulic fluids that is statistically significant at a defined level of confidence (usually 95%).

Energy Efficient Hydraulic Fluids – Demonstration in Mobile Applications

able 1 shows a categorization of hydraulic energy efficiency tests based on a Deutsch Norm developed for wear testing [1], together with examples of energy efficiency tests run by Shell Lubricants Technology. It can be seen that simplification of the test system leads to better control of the test conditions, with less random variation (“noise”) and a corresponding improvement in our ability to measure the “signal” (i.e. difference in performance due to a change in hydraulic fluid). However, the relevance of the findings to the end-user decreases in proportion. For example, the variation in a hydraulic fluid’s viscosity with temperature (viscosity index or VI) can be determined with a high degree of precision and clear differences demonstrated between products. Based on an understanding of the influence of fluid viscosity on overall hydraulic pump efficiency [2], a claim could be made that a very high VI fluid would give lower internal leakage, and hence improved volumetric efficiency, at elevated operating temperatures. However, this is a prediction based on one feature of the fluid (viscosity-temperature behavior) in one (albeit important) component of the hydraulic system - the pump (Category VI test). The next step-up in complexity is a test based on an individual system component (usually simplified) and carefully controlled operating conditions to minimize test variability (Category V test). An example would be an energy efficiency benefit due to reduced pressure losses when comparing two fluids in a laboratory filtration rig. Here, as in real-life, the result will be affected by more than one property of the fluid (e.g. viscosity,

Table 1: Categories of testing to demonstrate hydraulic fluid energy efficiency in mobile applications (based on DIN 50 322 ‘Wear Testing Categories’ [1])

resistance to the formation of gels and silts when contaminated, friction coefficient), and some operating conditions such as fluid flow, filter media, and/or filter construction may be close to those found in a real hydraulic system. Although again, this claim will be based on only one part of the hydraulic system. Probably the most widely used laboratory test to substantiate an energy efficiency benefit for a hydraulic fluid is to measure the overall efficiency (i.e. volumetric + mechanical efficiency [2]) of a full-size hydraulic pump operating at realistic pressures (e.g. 200 - 250

bar), speeds (2000 - 2400 rpm), flow rates and bulk fluid temperatures (Category IV test)]. These tests are usually based on rigs used for original equipment manufacturer (OEM) approval tests (e.g. Eaton Hydraulics 35VQ25 vane pump, Parker Denison T6H20C vane/ piston pump). Although these test stands also include other system components that can have an impact on system efficiency through interaction with the hydraulic fluid (e.g. pressure drop across the filter) or which could affect the fluid’s ability to deliver improved performance (e.g. viscosity loss due to shearing across a pressure relief valve), this type of test still generates results that are very dependent on only one part of the hydraulic circuit. There is a risk, for example, that results could be skewed in favor of very high VI fluids if the volumetric efficiency of the test pump is much lower than mechanical efficiency. At our technology center in Thornton we have also adapted the Eaton 35VQ25 vane pump test rig by including 20 metre of highpressure fixed pipe and flexible hose, with valves and bends, in an attempt to mimic a simplified hydraulic circuit present in a mobile piece of plant (Category III). However, as with all of these pump tests, no mechanical work is being performed.

Demonstration of Energy Efficiency Benefits Using Mobile Hydraulic Plant So far we have only discussed laboratory tests and their limitation in measuring the energy efficiency benefits in only one part of the hydraulic circuit— usually the pump. Clearly, the most realistic demonstration of the energy efficiency benefit of a hydraulic

fluid is to compare two products in a piece of mobile plant operating a realistic duty cycle (Category I test). Studies have been published where an excavator moves a pile of dirt a set distance over a set duty cycle (e.g. [3]). We have repeated this test using a Komatsu PC210LC-6K tracked excavator to compare an “energy-efficient” hydraulic fluid (ISO viscosity grade 32) with a typical ISO type HV mineral oil hydraulic fluid (ISO 32) and a SAE 10W diesel engine oil (39 mm2/s at 40oC, OEM recommended fluid for the

Although the test fluid gave an initial fuel consumption saving of around 20% per work cycle when compared to the SAE 10 W oil and a 10% saving when compared to the HV fluid, repeat tests yielded no statistical difference (95% level of confidence) between the sets of fluids. Despite the care taken to ensure that the duty cycle was consistent, there was still considerable “noise” in the test system, with variability coming from the operator (same driver throughout) and the load lifted and transported in each work cycle. It should be noted that if the random variation (“noise”) in a test is under-estimated, the “signal” (e.g. fuel consumption) may appear unreasonably large in comparison and may lead to the conclusion that fluids perform differently when in reality they do not. Shell has therefore developed a test protocol based on a complete piece of mobile hydraulic plant, operating at close to normal operating conditions but in a

computer-controlled work sequence (Category II test). Location of the machine at our Thornton research site meant that, with the exception of ambient weather conditions, many of the variables that had adversely affected the excavator field trial on energy efficiency substantiation could be controlled (e.g. weight lifted, duty cycle), eliminated (operator error), or measured and corrected for (e.g. ambient air temperature).

Shell Lubricants Technology - Telescopic Handler Energy Efficiency Test Protocol

Mobile telescopic handlers (telehandlers) are widely used in industry and agriculture to move and lift loads. They have a hydraulically operated telescopic boom, usually fitted with forks or a bucket, which can extend forwards-backwards and up-and-down. Shell’s test cycle and test run phases are illustrated in Fig. 1. With the exception of telehandler movement (omitted on safety grounds), this was considered to be a realistic duty cycle. The machine used is a Komatsu WH613 telehandler manufactured in 2005 (i.e. no breaking-in required) powered by a 4.5-liter turbo inter-cooled diesel engine. The hydraulic system is driven by a Bosch Rexroth variable displacement, axial piston pump with a maximum operating pressure of 260 bar, and a maximum pump flow rate of 142 liter/minute. The maximum weight that the Komatsu WH613 can lift is 3500 kg. However, as the boom acts as a lever, the load that can be lifted decreases rapidly as the working radius (distance between the front of the wheels and the centre of the load) increases. A 1 tonne concrete weight is used in the test. Automation is through a laptop-based SCADA (Supervisory Control and Data Acquisition) package that acts as the operator interface to enter control parameters and display real-time data feedback. The computer also interacts with a PLC (Programmable Logic Controller), which in a logical sequence, controls and measures all the instrumentation attached to the telehandler. Thermocouples measure the temperatures of the ambient air, engine air inlet, engine coolant, engine exhaust, diesel fuel, engine oil sump, bulk (i.e. reservoir) and pump outlet hydraulic fluid, and hydraulic cylinders. In addition, there are hydraulic fluid pressure and flow sensors. Proximity sensors are used to monitor engine speed, and draw-wire encoders determine boom travel and height. All the sensors are calibrated prior to, during, and after the test program. The boom movement under normal operating conditions is controlled by the telehandler operator using a joystick in the cab. In order to automate the test cycle, the PLC is used to control the proportional and directional valves of the hydraulic circuit. This design ensures that the

Energy Efficient Hydraulic Fluids – Demonstration in Mobile Applications

operation of the boom is similar to normal manual operations. Various safety features were employed to ensure that the telehandler could never travel beyond its safe operating restrictions and that no personnel could enter the test area while the vehicle was operating. Raw data are collected by the PLC system and then scaled for control and logging. Wonderware InTouch® SCADA communicates with the PLC system and collects scaled data for logging. Data are transferred at a rate of one updated value per second for all the instruments. Statistical analysis of the data is carried out using analysis of variance (ANOVA), as is standard for experiments of this type. Each test phase is treated as a separate response per measured variable; the analysis is then repeated for the extra response created by summing the fuel used over all the phases. This total fuel consumption over all five phases (“combined fuel consumption”) is obtained by dividing the total fuel used over the phases by the total duration of the five phases. This variable represents a combined duty cycle similar to the variety of loads and speeds that

could be encountered by a telehandler in routine daily operation. Many features of Shell’s telehandler test protocol, although developed independently, reflect the best-practice described in ASTM D7721 [4] and are summarized in Table 2. The test is capable of measuring ≥ 1.5% combined fuel consumption savings between a test and reference hydraulic fluid at a confidence level of 95% (or greater). Using this test protocol, with a range of test ISO 46 hydraulic fluids (viscosity index 140 to 200), the largest statistically significant fuel saving we have measured has been around 4%.

Conclusions

A test protocol has been developed which uses a typical piece of mobile hydraulic plant, operating at close to normal conditions, to compare the energy efficiency benefits of different hydraulic fluids. Many of the variables identified in ASTM Standard Practice D7721 as having a significant influence on the determination of efficiency benefits have either been eliminated, or measured

Keep Compressed Air Dry! It is vital to keep compressed air dry. Most compressed air systems have liquid water and water vapor, as a consequence of the compression of ambient air. Even if the atmospheric air at the compressor intake is only at 15% relative humidity, by the time the air is compressed to 100 psig (compression rate of 7.8), the compressed air is 100% saturated. Any cooling of the compressed air will allow liquid water to condense in the air lines downstream of the compressor. Liquid water can freeze at the worst possible time. Water vapor can’t be filtered out, but can be removed by efficient air dryers, especially during winter months when temperatures dip below freezing. If you experience water in your air lines, drain the water from the low spots in your piping, filter bowls, and check those “automatic” drains to make sure they are working properly.

What’s in Your Toolbox? As technical trainers we’ve seen many interesting toolboxes across the country. One thing that has surprised us both is some lack of understanding when it comes to calibrated precision tools. Be it a torque wrench, pressure gauge, dial indicator, or digital volt ohm meter (DVOM), many technicians neglect to have their tools tested or calibrated on a regular basis. As technology increases in hydraulic systems, the need for properly calibrated precision tools and test equipment does, too. If you haven’t had your tools and test equipment calibrated recently, you may not be getting the results you need

Why is my Air Valve Leaking out the Exhaust? A customer purchased and installed a 4-way air valve, however air leaked continuously out the exhaust port of the valve just like the old one he was replacing. He bought a second new valve, installed it, and experienced the same thing. Logical troubleshooting dictates using a holistic approach; in other words, looking at the entire circuit as an entity, then narrowing the problem to specific component(s). Looking at all the potential suspects in a simple circuit with a single 4-way valve and double-acting cylinder, possible internal leak paths include the following: • Valve internals: contamination, worn or damaged seals or bore, or not shifting fully • Body to base gasket: damaged, missing, or installed incorrectly • Cylinder internal leakage: worn piston seals, damaged tube, or contamination The original cylinder had not been changed, so the customer carefully disconnected the un-pressurized line between the valve and cylinder to see if air was coming from the valve or the cylinder. Air was coming from the cylinder port, which confirmed the leak was internal bypass in the cylinder, not the valve. The point where the leaking air was escaping was at the exhaust of the air valve, leading him to think the air valve was the issue. Don't assume the symptom and the defective component are always at the same location.

How to Correctly Interpret C a s e D r a i n F lo w s i n H y d r o s tat i c T r a n sm i ss i o n s By B r e n da n C a s e y , H y d r a u l i c S u p e r m a r k e t . co m

When a pump or motor is worn or damaged, internal leakage increases and therefore the flow available to do useful work decreases. This means that the condition of a pump or motor can be determined by measuring the flow from its case-drain line (internal leakage) and expressing it as a percentage of its theoretical flow. However, using case drain flows to determine the condition of a hydrostatic transmission, without a thorough understanding of closed circuits, can lead to incorrect conclusions and the costly change-out of serviceable components.

ervoir by the charge pump charges the low-pressure side of the loop through the check valve located close to the transmission pump inlet. The volume of hot fluid leaving the motor outlet that is not required to maintain charge pressure in the low pressure side of the loop vents across the purge valve relief into the case of the motor and back to tank—sometimes via the transmission pump case.

Drain-Line Gymnastics Hydrostatic Transmission Basics A hydrostatic transmission usually comprises a variable-displacement pump and a fixed or variable displacement motor, operating together in a closed circuit. In a closed circuit, fluid from the motor outlet flows directly to the pump inlet, without returning to the tank (Fig. 1). As well as being variable, the output of the transmission pump can be reversed, so that both the direction and speed of motor rotation are controlled from within the pump. This eliminates the need for directional and flow control valves in the circuit. Because the pump and motor leak internally, which allows fluid to escape from the transmission “loop” and drain back to tank, a fixed-displacement pump called a charge pump is used to ensure that the loop remains full of fluid during normal operation. In practice, the charge pump not only keeps the loop full of fluid; it pressurizes it to between 110 and 360 psi, depending on the transmission manufacturer. A simple charge pressure circuit comprises the charge pump, a relief valve, and two check valves, through which the charge pump can replenish the transmission loop (Fig. 2). Once the loop is charged to the pressure setting of the charge relief valve, flow from the charge pump passes over the relief valve, through the case of the pump or motor or both, and back to tank. A variation to this charge circuit arrangement is where the transmission is fitted with a purge valve 28

(also called a transmission valve or replenishing valve or flushing valve). Because the fluid in a closed circuit flows directly from the motor outlet to the pump inlet, it means that apart from losses through internal leakage, the same fluid circulates continuously between pump and motor. If the transmission is heavily loaded, the fluid circulating in the transmission loop can overheat. The function of the purge valve is to positively exchange the fluid in the loop with that in the reservoir. A closed-circuit purge valve usually comprises a pilot-operated directional valve and a low-pressure relief valve (Fig. 3). When the transmission is in neutral, the directional valve is centered and the gallery to the low-pressure relief valve is blocked. In this state, the purge valve has no function and the charge relief valve in the transmission pump (Fig. 2) regulates charge pressure. When the transmission is operated in forward or reverse, the high-pressure side of the loop pilots the directional valve. This opens the lowpressure side of the loop to the purge relief valve gallery. This purge relief valve is usually set around 30 psi lower than the charge relief valve, and therefore it regulates charge pressure when the transmission is operating in forward or reverse. A purge valve is most effective when it is located at the motor, assuming the charge check valves (Fig. 2) are located in the transmission pump, as is the norm. The effect of this is that cool fluid drawn from the reswww.fluidpowerjournal.com | www.ifps.org

This arrangement is important to keep in mind when using case drain flow to determine the condition of a hydrostatic transmission because charge pump flow must be taken into account. Consider an example where charge pump flow is 10 gpm, of which 4 gpm is leaking out of the loop through the motor’s internals (case drain) and 2 gpm is leaking out of the loop through the pump’s internals. The balance of 4 gpm must therefore be going over either the charge or purge relief valve—but still ends up in the pump or motor case, depending on the location of these valves. Before any meaningful conclusions can be drawn, the case into which the charge or purge valve relief is dump-

ultimately destroy itself. The trick is to overhaul the transmission before this point is reached!

If a charge pump with a flow rate of 1 gpm is installed in the circuit, the problem is solved, temporarily at least. With 1 gpm leaking out of the loop and 1 gpm being replenished by the charge pump, the status quo is maintained—until wear causes the internal leakage of the transmission pump and/or motor to exceed 1 gpm. As you can see, it’s not possible for the internal leakage of a hydrostatic transmission to exceed the flow rate of its charge pump. Charge pump flow rate is typically 20% of transmission pump flow rate. This means that volumetric efficiency can drop to 80% before the transmission will start to cavitate and

3 ing (motor or pump) must be determined, and if connected, the two case drain lines (motor and pump) must be isolated from each other. If the charge or purge valve relief vents into the case of the pump, then it is possible to determine the condition of the motor by measuring its case drain flow, but not the pump. If the charge or purge valve relief vents into the case of the motor, then it is possible to determine the condition of the pump by measuring its case drain flow, but not the motor. In other words, it is not possible to determine the condition of the component that has the charge or purge relief valve dumping into it because there is no way of telling what proportion of the total case drain flow is due to internal leakage—unless the relief valve can be vented externally while the test is conducted. When conducting these tests, it is also important to understand that the volume of internal leakage from a hydrostatic transmission cannot exceed the flow rate of its charge pump. Consider for a moment, a transmission that has a volumetric efficiency of 100%, that is, the pump and motor have no internal leakage. The transmission loop has a total volume of two gallons and is full of fluid. Because there is no internal leakage, there is no need for a charge pump. When the pump is stroked to maximum displacement, this circulates the two gallons of fluid in the loop at a rate of, let’s say, 50 gpm. Because it’s a closed loop, with no leakage, the flow from pump to motor is 50 gpm and the flow from motor to pump is 50 gpm. Now let’s introduce internal leakage of 0.5 gpm in each of the pump and motor. The result is that, with no charge pump, after one minute there will only be one gallon of fluid left in the loop (the other gallon will have leaked back to tank). However, within a second of the transmission starting to leak, the transmission pump will start to cavitate and the severity of this cavitation will increase with each passing second until the transmission destroys itself.

Pressure & Vacuum

in Print By Dan Pascoe

In the printing industry, vacuum and low-pressure air is used extensively in the sheet feeding heads of web offset printing presses (Fig. 1). These presses utilize vacuum throughout the machine to transfer sheets of plain paper from one end to the finished printed paper at the other. Common printing projects are large quantity runs of catalogue pages, brochures, posters, and other color or grayscale material. Plain sheets of paper are placed at the front of the press. The sheet is lifted and “dragged” into a mechanical conveyor with vacuum cups (Fig. 2). The vacuum cups lift the top sheet while a static brush head helps to prevent the sheets underneath from being lifted, as well. Low-pressure air blows into the side of the sheet to aid

sheet separation (Fig. 3). he vacuum and low-pressure air is often generated by what is referred to as a “pressure-vacuum” pump as shown connected to a press (Fig. 4). This pump, which looks similar to a standard sliding vane vacuum pump, gen-

erates both vacuum and low pressure, pulsation-free air, at the same time. The vacuum port is connected to the vacuum cup line(s), whereas the exhaust port of the pump is connected to the low-pressure air lines. This type of pump offers the advantage of a single pump producing both vacuum and air for the sheet feeder and is a very easy solution for this task.

Fig. 2

However, the pump is quite large with typical models that generate >10 cfm weighing in excess 50 lbs. Therefore, these pumps should be mounted either on the floor or in a frame on the side of the machine. Consequently the distance from the actual vacuum cups and air knives could be considerable.

A sheet feeder usually consists of only four to eight 1" diameter (25 mm) cups (depending on the size and weight of the paper being printed), and therefore the vacuum generator does not need to be large. A typical generator for this application would only require about 4 cfm of compressed air to operate. This equates to about 1 hp of compressor power. The same type of vacuum generator can be used for the low-pressure air as well, simply by connecting the low-pressure airlines to the exhaust of the unit (Fig 5). In this case a vacuum filter is placed on the inlet to prevent impurities from contaminating the venturi. The principle of a multi-stage generator is

to create more vacuum flow than single-stage models per unit of compressed air consumed. A typical multi-stage vacuum generator that uses 4 cfm of compressed air will actually amplify the exhaust by about 4:1. Therefore >16 cfm will be provided at the exhaust—ideal for sheet separation. The other benefit of air-powered vacuum generators is that, if filtered properly, they will provide virtually maintenance-free ownership. The generator shown in Fig. 5 also utilizes an “energy saving” kit. This will turn off the compressed air automatically to the generator if the vacuum level reaches a preset point. Therefore, when the press

Fig. 1

As a result, these pumps are often oversized to compensate for this distance. The vacuum levels being generated are lower than standard sliding vane pumps as the exhaust is being restricted by the lowpressure air application. Maximum vacuum is usually about 18"Hg at the pump. As is typical with printing presses, the installation of the vacuum lines is complicated with many joints and flow restrictions, and therefore by the time vacuum is seen at the vacuum cups, the vacuum level has dropped considerably. Of course the vacuum cups do not require a high vacuum level so this technology does work well, but consideration should be made to alternatives to traditional pressure-vacuum pumps if the opportunity arises for the user. Because these pumps run continuously, the maintenance requirements are frequent. This normally consists of basic maintenance, which in this case is a vane kit replacement, but this can be very costly over a 12-month period and sometimes require a technician outside of the facility to undertake this task. An alternative to the pressure vacuum pump could be an air-powered vacuum generator (Fig. 5). These multistage generators offer adjustable vacuum levels depending on the compressed air inlet pressure, and being very compact and lightweight, they can be placed much closer to the point of use—the vacuum cups. If used properly, the air-powered vacuum generator (venturi) can use the same amount of energy and in most cases, much less. As the inlet pressure is fully adjustable, the user can use the minimum compressed air pressure, which in turn will minimize the compressed air consumption.

Pressure & Vacuum

in Print stops, the vacuum level will rise and the compressed air is turned off, turning on again as soon as the press restarts. More often than not, vacuum pumps with electrical motors keep running if the press is in a standby state, regardless of whether or not the press is being used for actual printing. Sheet feed web offset presses are often supplied to customers with the pumps included, which offers a complete turnkey “ready to go” press. Smaller printing shops often do not have the necessary compressed air available to operate the vacuum generators. However, in larger facilities with centralized compressed air systems, vacuum generators could offer a very viable and efficient alternative to the pressure-vacuum pump. This article is intended as a general guide and as with any industrial application involving machinery choice, independent professional advice should be sought to ensure correct selection and installation.

FPEF – Fluid power educational foundation

Fluid Power Educational Foundation Receives Substantial Donation The Fluid Power Educational Foundation (FPEF) received a $150,000 donation from The Mackey Foundation in memory of Bruce B. Mackey. This donation will allow the FPEF Board of Trustees to commit to an increase in scholarship monies to students attending FPEF Key Schools, institutions that have concentrated fluid power programs, beginning with the 2013 school year. Bruce B. Mackey (1924-2010) founded Main Manufacturing Products, a hydraulic flange manufacturer in 1959 in Grand Blanc, Mich. Mr. Mackey was a fluid power instructor in the 1960s and 1970s, and was a dedicated proponent of fluid power education. “The Educational Foundation is extremely pleased to have been given this bequest. In these trying economic times, fundraising for an organization such as ours is quite a challenge. It is gratifying to be remembered by long-time industry leaders and friends of fluid power education,” said Liz Rehfus, CFPE, CFPS, FPEF chair.

About the FPEF The Fluid Power Educational Foundation (FPEF) was formed in 1982 to stimulate, advance, and support the sciences and technologies of hydraulics and pneumatics in North America. In pursuit of this purpose, the Foundation supports education and research initiatives that provide meaningful impact to the advancement of the fluid power industry. The Foundation is wholly supported by fluid power industry individuals, firms, and associations, which enable FPEF to bring fluid power to students of all grade levels. Additional information can be found by contacting FPEF at 856-424-8998 or by visiting www.fpef.org.

CCEFP – The Center For Compact And Efficient Fluid Power

Portable Micro-Excavator a Powerful New Teaching Tool

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!

A micro-excavator, powered by water hydraulics or pneumatics and small enough to fit in a hand-carried storage bin, is being used as a new platform for understanding the importance of fluid power and to provide insights into the technology itself. This learning resource is well-suited for many audiences, too—in classrooms, museums, even in corporate lobbies. As one of the CCEFP’s education and outreach projects, the microexcavator was built and developed under the direction of Professor John Lumkes at Purdue University. His project team has included a number of his engineering undergraduate and graduate students, most notably Jose Garcia, now a professor at the Illinois Institute of Technology; high school teachers in Project Lead The Way; and the staff of the Minnesota Science Museum. The National Fluid Power Association assisted the CCEFP in providing financial support. “Based on our extensive field tests with students in and out of school settings, we know that the micro-excavator is an effective hands-on teaching tool that makes it fun to learn about engineering principles while seeing first-hand how fluid power technology works,” said Professor Lumkes. The accompanying curriculum guide ISO 9001:2008 CERTIFIED COMPANY lays out effective strategies for maximizing the teaching power of the micro-excavator.

NFPA Education and Technology Foundation Awards Three Gifts for Spring 2012 Projects Cleveland Community College, Illinois Institute of Technology, and Purdue University are the recipients of the Spring 2012 semester gifts from the NFPA Education and Technology Foundation. Each gift will help strengthen interest in fluid power on their campuses and help the Foundation in its efforts to attract some of the best and brightest students to the field. The Foundation has awarded 21 gifts and one grant to 16 schools to date. These awards align with the organization’s strategy to bring fluid power to as many students as possible through its growing list of educator members.

Following are brief overviews of each project: Cleveland Community College – Fluid Power in Automation By Professor Mark Gengler The goal of this project is to develop industry-specific, high skill level training components for a credit course at the two-year college level for automation application in the fluid power industry. Intended benefits of the project are to develop and provide industry-specific training in fluid power applications in automation systems. Consequences include an increased interest and application of fluid power in automation systems, and the project will act as a foundation for future courses to be developed with similar concepts.

NFPA Fluid Power Challenge Exposes 1,500 Students to Fluid Power The end of 2011 brings a close to another successful year of NFPA Fluid Power Challenge events. Since the program began in the U.S. in 2008, more than 1,500 students in six states have been exposed to fluid power technology. The Challenge events that took place this fall were sponsored by Deltrol Fluid Products (at Harper College, Palatine, Ill.); Daman Products Co. Inc. (at Notre Dame University, Notre Dame, Ind.); and at MSOE—the Milwaukee School of Engineering (Milwaukee, Wis.). This number keeps growing. Wojanis Supply Co., Inc. is planning another Challenge event in April and May at the Community College of Allegheny County in Oakdale, Penn. “Exposing students to fluids and engineering problems is all new to them,” said one middle school teacher in Indiana. “But this exposure is invaluable because they may have gone through life without even knowing the possibilities of fluid power. You have turned on their radar to look for examples of fluid power and engineering in the world around them.” New this year, the winning team from each location will receive national recognition. A review committee will evaluate the portfolio and two-minute competition video from each winner, and then select those meritorious of special awards. For further information contact Carrie Tatman Schwartz at ctschwartz@nfpa.com or (414) 778-3347.

Illinois Institute of Technology – Multiple Configuration Hybrid Hydraulic Transmission Demonstrator By Professor Jose Garcia The goal of this project is to design and build a test setup to show students diverse alternatives for hybrid vehicle propulsion using fluid power technology. Specifically, this project seeks to build a demonstration setup that can be electronically controlled to replicate a scale model of a series or parallel hydraulic drive train. Purdue University – Test Bench for Energy Efficient Active Oscillation Damping on Mobile Hydraulic Machines By Professor Andrea Vacca The goal of this project is to expose Purdue students to the aspects of valve-controlled hydraulic systems. The gift will permit the completion of an existing experimental apparatus that will not only better expose students to fluid power related topics, but also captivate students on advanced issues related to control of hydraulic systems. Additional information about the Spring 2012 semester gifts and previously awarded gifts can be found at http://www.nfpafoundation.org/Grants/ CurrentProjects.aspx. If you would like to learn more about the gift program, please contact Sue Chase at (414) 778-3376 or schase@nfpa.com.
