New Trends:

Energy Saving in Pneumatic Systems

Photo by: Todd Umholtz

Energy conservation has been much talked about lately in the media, the government, and at the water cooler. Lean manufacturing is also a popular topic these days, as are any ways to increase productivity, reduce costs, and increase profitability.

One topic that has historically been overlooked is the cost of compressed air in a facility. Studies conducted over the years by SMC Corporation of America have suggested that, of the energy consumed by a typical factory, 20% goes to the production of compressed air. Of that 20%, it’s often the case that at least 30% of that energy is wasted by leaks.

Detecting and correcting leakage would seem to be of significant benefit, both in reduced operational Jon Jensen, costs and in increasing environmental responsibility, SMC Corporation of America, so why does a typical factory still spend 30% of the 2011 IFPS President energy used to compress air on leaks?

The answer is that leak detection is a costly and time-consuming maintenance activity, both in labor costs and in equipment required. The typical method has been to employ an ultrasonic leak detector, essentially pointing it at every component, and listening for leaks. In a busy factory, this is difficult at best and only effective if done on a regular basis. This method also calls for checking numerous components that are actually NOT leaking.

Emerging technology such as SMC’s Automatic Leakage Detection System (ALDS) is able to quantify the amount of leakage on a machine and also define which branch of the system is actually leaking. Imagine the benefits if maintenance personnel can easily determine that there’s a leak to fix and be directed to the component that requires attention. Not only will there be an increase in productivity, but leaks will be addressed before they have a chance to eat up the profits!

Sound good to you? It certainly does to me. In today’s competitive marketplace, any opportunity to increase productivity, reduce costs, and increase profitability is well worth exploring.

Employing new technologies such as the ALDS is only part of the picture, however. It is still important to not overlook the basics. No matter how cutting-edge the technology is, or how “automatic” the processes become, there is still a need for qualified, competent individuals to design, install, and operate fluid power machinery.

One initiative that the International Fluid Power Society is currently working on is a “Best Practices” manual, which will contain numerous recommendations on how to design, build, install, operate, and maintain efficient fluid power systems.

After all, if things are done correctly in the first place, energy conservation should take care of itself.

During my tenure as president of the IFPS, I hope to raise awareness of energy conservation while stressing the importance of fluid power certification, education, and training. I am looking forward to the publication of the “Best Practices” manual and hope to see continued interest in improving the skills of our valuable industry professionals.

Here’s to a productive and peaceful 2011!

New Hybrid Technology in Use

E

aton Corporation’s Hydraulic Launch Assist™ (HLA®) technology is designed to improve both the fuel efficiency and overall operating economy of vehicles with “stop-and-go” duty cycles by capturing braking energy and then using it to help accelerate the vehicle. The company supplied prototype HLA systems for 12 refuse trucks built on Peterbilt chassis as part of a test and evaluation program funded by the Houston Advanced Research Center (HARC) in Texas.

While the Texas climate is ideal for hot-weather testing in near-sea level conditions, the development program also required data from a cold, high-altitude location. The City of Denver is a leader in the application of “green” technologies including bio-diesel and hybrid vehicles, so arrangements were made to supply one of the prototype vehicles to the City of Denver.

The Challenge The City has very aggressive goals for reducing emissions and moving toward sustainable energy sources like bio-diesel. Like all government entities, Denver also has a mandate to minimize both the operating and life cycle costs of its vehicle fleet.

For its part, Eaton hybrid development team needed real-world data on the interaction of the HLA system with the vehicles Anti-Lock Braking System (ABS) on snow and ice.

Denver in 2008 and immediately went into service.

Denver’s refuse collection trucks average 8,400 miles per year with an average fuel efficiency of 2.3 miles per gallon. The trucks are operated year-round, providing extensive data on HLA system performance under severe cold, and on the integration with the truck’s ABS system on snow and ice.

The Results The City estimates that the HLA-equipped truck has achieved a 25% fuel economy improvement.

This falls in line with a goal strongly supported by Denver Mayor John Hickenlooper’s Greenprint Denver Initiative.

The City also anticipates a significant improvement in brake life because the HLA system recovers and stores most of the kinetic energy usually absorbed

by the brakes. This expectation is supported by the data from the trucks being used in Texas.

A non-hybrid truck typically requires brake replacement every three to four months at an average cost of $2,000.

The integration of the HLA technology and ABS systems has performed flawlessly through a severe Colorado winter, providing one of the last confirmations required before putting the heavy-duty version of the HLA system into production.

The HLA has been in production since October 2009 with several dozen cities enjoying the benefits of this hybrid system.  For more information, contact Robert Golin, Eaton’s

Hydraulic Group, Tel: 952-937-7312 or e-mail: robertygolin@eaton.com.

We anticipate an annual reduction in excess of 1,600 gallons of fuel compared to our non-hybrid fleet of similar vehicles – Nancy Kuhn, Fleet Administrator, City of Denver Public Works Fleet Maintenance Division

Vacuum Law

By Daniel Pascoe

Vacuum is a pressure condition and can be defined as a known volume of air under a lower pressure than the air surrounding it. Therefore, if you generated a vacuum condition inside a vacuum vessel, the air on the outside of the vacuum vessel is higher than that on the inside. Consequently, if you had a small leak in the vacuum vessel, air “rushes” into this void to equalize the two pressure areas. Simple enough to visualize.

One of the more confusing and misunderstood vacuum problems facing engineers is how to compensate for leakage in a vacuum system. Very much like the leak on the vacuum vessel, how do you correctly size a larger vacuum pump to compensate for the leakage and enable the system to maintain a vacuum level of choice rather than a consequence?

Fig 1 shows a simple vacuum system comprised of a compressed air vacuum generator, tubing between the vacuum generator and vacuum cup, and a vacuum gauge. The product being handled is a small cardboard box that has a leak due to the porosity of the cardboard material. How do you calculate the size of vacuum generator that will create a higher vacuum level than that being experienced? If the vacuum generator is capable of 10 scfm maximum vacuum flow, a maximum vacuum level of 27"Hg, and the vacuum level being generated is only 15"Hg, it is

because air is being drawn into the system through the cardboard box. Therefore, if you want to create a vacuum level of 24"Hg, what size vacuum generator do you need to overcome this leakage?

Boyles Law can be used to determine this larger vacuum generator. More details concerning this law can be found at http://en.wikipedia.org/wiki/Boyle’s_law.

Boyles Law states that P1 x V1 = P2 x V2 where the following is applicable: P1 - The existing pressure (vacuum level) P2 - The pressure needed (desired vacuum level) V1 - The volume of vacuum flow produced by the current vacuum generator V2 - The volume of the larger vacuum generator needed

IMPORTANT

– The vacuum level MUST be in an absolute measurement. Therefore, the following applies:

P1 - 15"Hg(a) (30"Hg-15"Hg) P2 - 6"Hg(a) (30"Hg-24"Hg) V1 - 10 V2 - ?

V2 is what we want to know. Transpose this formula and you have the calculation shown in Fig 1.

As the calculation demonstrates in Fig. 1, the vacuum generator needs to increase to 25-scfm vacuum, which is a factor of 2.5 compared to the original 10-scfm unit.

This simple calculation removes the guesswork and indeed unnecessary cost often associated with this type of improvement exercise.

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.

P1 V1 = P2 V2 V2 = P1 V1 P2 V2 = 15 x 10 6 V2 = 25 Fig. 1

GREEN AIR

T

he use of compressed air needs a new approach. Almost every manufacturing operation would benefit from a compressed air specialist who reports to the general manager. If the general manager were reminded of the amount of waste in the cost of compressed air, real and effective changes would surely follow.

Global economy and competition dictates survival of the fittest to the international manufacturing community. The international explosion of knowledge, transportation, and the capability to manufacture goods or provide services without geographic boundaries changes the game. The compressed air system has many possible improvements.

Those who have compressor experience and expertise may know what won’t work and why, but consider the following: 1. Intake Filter • If most of the “junk” in compressed air is ingested, would an intake filter with the same filtration used in a (HEPA filter) vacuum cleaner keep most or more of that out?

• On compressed air systems, would a bag house approach clean the air well without undue restriction?

2. Compressor • There have been some recent interesting comments about variable speed drives for compressors where some compressors “unload” and free wheel when top pressure is achieved. The variable speed drive, similar to cruise control on an automobile, might only use the power to do work.

• Would a larger fly wheel benefit rotary compressors with increased momentum?

• Would a hybrid power supply for compressors move electrical demand off prime time?

3. Cooling and Transport • The cooler temperature below ground offers removal of heat from compressed air without power requirement.

• Oversized plumbing slows the air for better cooling and much less pressure drop.

4. Condensate and Debris Removal • A timed drain valve will discharge condensate with good access.

5. Ready Air • The underground plumbing may be under the building foundation, parking lot, walkway, lawn, or any combination.

• Generously oversized subterranean plumbing provides a reservoir effect and better cooling.

• Exposure above ground prior to usage will warm the cool compressed air and pipes.

As the air enters the work area after steps 1 through 4, it should be slightly cleaner and dryer with less pressure lost at lower cost than most systems. Some of this compressed air may be used as is. Deal with other requirements as needed.

Professionaldevelopment

Get Competent to Work Safe: A Tale of Two Sites Taking the Mystery out of Competency In the business of safety, we talk about competency and use the term “competent person.” OSHA refers to and requires competent persons in several of its standards and defines the term as “one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them” [29 CFR 1926.32(f)]. Yet many managers, supervisors, and leaders find it difficult to know how to apply this definition. Looking at the two primary components (capability to identify hazards and authority to correct them) helps clarify the definition.

We typically train employees to do the tasks required to do their work and test to make sure they have the required knowledge and demonstrated ability. This is how most companies determine technical competency. Hazard recognition and control is sometimes part of the training. We then assume that employees know they have the authority to control the hazard or stop the work if conditions are unsafe. However one variable is missing: the willingness to take responsibility.

Two Sites, One Missing Factor The willingness to take personal responsibility is strongly linked to a person’s values and their acceptance of accountability. This becomes clear when considering the comments made recently by workers at two work sites. At the first site, employees said “I got bit by a spider and they asked me if I could have prevented the bite! How am I supposed to know when a spider is going to bite my leg?”

“My boss asked me the other day how I got poison ivy. How can I stay out of poison ivy when I’m tromping through tall grass to get to my work?”

“We’re in such a hurry to get the work done around here that I don’t have time to put all that stuff away off of my truck. It won’t hurt anyone here on the dock.”

At a second site, we heard employees say “It doesn’t take long to put everything back where it goes around here – maybe an extra five or ten minutes at the end of the day. I don’t want to have to worry about tripping over tools and materials the next day, and I sure don’t want my buddies to get hurt.”

Creating the Competent Mindset Making a jobsite safe requires a specific goal: nobody gets hurt. The strategy to reaching that goal is to recognize and control hazards. It’s like planning a trip across country in a car or plane. First you choose a destination (goal) and then map the best way to get there (strategy).

One way to describe a competent person is one who demonstrates through their actions and behaviors those competencies required to be successful at a task.

If the task is to prevent your own and others’ injuries, then to be a competent person, you need to know what to do to prevent injuries, recognize what causes them, and want to do what it takes to work safe. In other words, people around you perceive that you are mentally positive about safety and physically demonstrate your belief.

Zig Ziglar, a great motivator and thinker, said, “Whether you think you can or think you can’t, you’re right.” Can you be a competent person? Certainly. Use the following questions to help you self-assess where you are with regard to being a “competent person”: • What have I done to make sure that I understand the technical knowledge and skills required for my work?

• What do I know about the hazards associated with my work and what else do I need to know more about?

• What assumptions do I make about the safety of the work I do? Am I using my opinion or facts?

• How am I using my authority and responsibility for safely performing my work?

• What questions should I be asking my manager, supervisor, or leader so I can be recognized as a competent person?

These are only a few of the questions you can ask yourself to determine the strengths you have as a competent person. You may find some areas where you want to increase you knowledge, skills, and abilities. By starting with yourself, you can determine how competent your work site is.

“I had to work in an area today that is usually infested with spiders and insects.

I heard them talk about the new repellant at the safety meeting last week, so I went by the storeroom and got some. It worked well. I didn’t get any bites, and I’m glad I listened to the guy at the meeting.”

“We were getting ready to do a new job and I asked my supervisor if he thought there was poison ivy in the tall grass. We weren’t sure. He had us spray the area and we went back the next day and did the work. Some of the guys on my crew get poison ivy easily, and we didn’t have any problems this time. It helps to take a little extra time to spray.”

It’s not hard to recognize the difference in the mindsets at these two work sites. Did the hazards (spiders, poison ivy, and poor housekeeping) require highly technical skills? Probably not. Were the employees authorized to deal with these types of hazards that can cause injury or illness? Without a doubt. What was the difference? Sure, leadership and company culture are factors; however, the primary variation here is the degree to which workers are willing to take personal responsibility for making the workplace safe for themselves and others. It’s not hard to figure out which site most people would choose as their workplace.

Another Way to Increase

Hydraulic System Efficiency

I

n the current trend of increasing energy costs, which appears to be underpinned by big-picture issues such as peak oil and carbon emission reduction, there is a growing awareness of the need to make hydraulic systems more efficient.

The three obvious ways of doing this are 1. Using components with higher native efficiency (for example, a piston pump instead of a gear pump) 2. Minimizing the use of energy-loss devices, such as flow controls, pressure reducing valves, and even proportional valves 3. Designing the circuit so that energy is not consumed when work is not being done (for example, unloading the pump between cycles or employing load-sensing control)

But there’s also another way to increase the overall efficiency of a hydraulic system: Specify a better oil.

Hydraulic oil is a lubricant and a power transfer device. To be most efficient in its role as a power transfer device, hydraulic oil needs high bulk modulus (high resistance to reduction in volume under pressure) and high viscosity index (low rate of change in viscosity with temperature).

As an analogy, consider the tension on a vee belt.

If it is out of adjustment, the belt will slip. The result is a higher percentage of input power wasted to heat.

This means less power is available at the output to do useful work. In other words, the drive becomes less efficient.

A similar situation can occur with hydraulic oil.

Change in its bulk modulus and/or viscosity can affect the efficiency with which power is transferred in the hydraulic system.

As I have explained in previous articles, the perfect hydraulic fluid for transmission of power would be infinitely stiff (incompressible) and exhibit a constant viscosity of around 25 centistokes regardless of its temperature. Such a fluid does not exist.

Bulk modulus is an inherent property of the base oil and can’t be improved with additives. But viscosity index (VI) can be improved by using high VI base stocks such as synthetics and/or by adding polymers called Viscosity Index Improvers to the formulation.

16

Viscosity Index Improvers were first used to make multi-grade engine oils in the 1940s. These days, this common and well-tested technology is used to make high VI oils for other applications, including automotive transmission fluids and manual transmission gear oils. However, the VI improvers used in oils for the above applications are not typically shear stable when used in modern hydraulic systems. But recent advances in VI improver technology means that mineral hydraulic oils with a shear-stable viscosity index in the 150 to 200 range are now commercially available.

While this may be good to know, how can these high VI oils improve the overall efficiency of a hydraulic system? Well, within the allowable extremes of viscosity required to maintain adequate lubricat-

ing film thickness for hydraulic components, there’s a narrower viscosity range where power losses are minimized, and therefore, power transfer is maximized.

By maintaining the oil’s viscosity in this optimum range, machine cycle times are faster (productivity is increased) and power consumption (diesel or electricity) is reduced.

So using a higher VI oil means the hydraulic system will remain in its power transmission “sweet spot” across a wider operating temperature range. You could think of this as similar to installing an automatic tensioner on the vee belt drive we talked about earlier to maintain optimum power transfer conditions.

The results of field trials conducted by a manufacturer of shear-stable VI improvers1 have demonstrated significant improvement in overall efficiency—and real economic benefit to the hydraulic equipment end-user.

In one trial, the performance of a 40-horsepower compact excavator was evaluated using an all-seasons 142 VI “baseline” oil and compared to the performance of the same machine using a 200 VI “test” oil.

Fig. 1: Cost/benefit analysis of changing to 200 VI shear-stable hydraulic oil1 www.fluidpowerjournal.com | www.ifps.org

The test procedure was as follows: Run baseline data with 142 VI oil: 1. Start with new air filter and fuel filter.

2. Top off fuel to fill neck at start of test.

3. Trenching blade width to normal depth.

4. Dig trench for seven hours.

5. After seven hours, record fuel to refill.

6. Measure trench width, depth, and length.

7. Repeat steps 2-6 with second operator.

8. After baseline established, change oil and filter, run for 2 hours, and repeat oil and filter change with 200 VI oil.

9. Repeat steps 2 through 7.

The higher VI test oil demonstrated the following advantages over the baseline fluid: • 15.4% improvement in “Fuel Economy” - cubic yards of dirt moved per gallon of fuel consumed.

• 14.3% improvement in “Productivity” cubic yards of dirt moved per hour.

To assign a value to these performance gains, a spreadsheet was developed to calculate an owner’s variable costs over the 1,000-hour drain interval recommended by the excavator manufacturer. The following assumptions were made: • All seasons baseline oil cost $9 per gallon and the 200 VI test oil $18 per gallon.

• Labor and equipment rental cost of $75 per hour.

• Diesel cost of $3.15 per gallon.

From extrapolating the results of the trial, it was determined that with the baseline oil, the excavator could dig approximately 20,000 yards of trench in 1,000 hours. And the same amount of trench could be dug in 874 hours with the 200 VI test oil. No value was assigned to the additional 126 hours the machine owner would have to undertake additional work.

Based on the field test results and the assumptions stated above, replacing the 142 VI all seasons oil with 200 VI oil would save the machine owner $10,000 every 1,000-hour drain interval (Fig. 1). When filled with a 200 VI oil, the machine tested does more work and uses less fuel; its overall efficiency is significantly improved.

Of course, there are many variables that can influence the performance of a hydraulic machine. But the efficiency gain which may be achieved by switching to a high VI oil is something every savvy machine designer and hydraulic equipment user should be aware of.

Timothy White

Q:

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

I started my fluid power career as an apprentice at Puget Sound Naval Shipyard. My career progressed into ultra-high pressure water blasting where I was responsible for maintaining the pumps and recovery systems. I eventually left there to work in field service for a water blasting company. Shortly after I started, we found out that my wife was pregnant and decided that being on the road was not a good idea. I then moved to the Boeing Company.

Q:

What is the most memorable moment in your fluid power career and what did it teach you?

The most memorable moment for me came when I was given the opportunity to travel to Philadelphia, Pa., to attend the International Fluid Power Society (IFPS) 50th anniversary celebration. I was asked to speak during the Certification Committee meeting about why I chose to become certified through IFPS. It was pointed out during that meeting that I am one of only 20 people involved with IFPS to hold all certifications. It was further noted that I am the only maintenance person to hold that distinction.

Q:

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

I have never really thought about achievements in the industry. I guess as a maintenance person, I would have to say ease of system maintenance, efficiency, and system reliability. Making systems easier to work on translates into less downtime and higher production rates for our customers.

Q:

How and why did you get involved in the IFPS? I got involved with the IFPS as a way to increase my knowledge and skills. I went to an Intermedi-

January/February 2011

ate Hydraulics class at the Boeing Company and the instructor (Rickey Rodeffer, IFPS 2010 president) talked about the IFPS. I decided that I would check it out and started studying for the IFPS Industrial Hydraulic Mechanic certification.

Q:

Why would you encourage industry professionals to join the IFPS? I would recommend that industry professionals join the IFPS as a way to network with other industry professionals. There are great people with a tremendous amount of knowledge for IFPS members to tap into.

Q:

What have you personally gained by being a part of IFPS and how has it helped your career?

I have the opportunity to partner with other industry professionals and expand my own personal knowledge base of maintenance practices and troubleshooting skills. I have the ability to learn that other industries have some of the same maintenance issues that I experienced and I can learn new methods that will improve my own skills.

Q:

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

I am not sure where the industry is headed, but I am excited to see where it may go and be along for the ride.

Timothy can be reached at timothy.m.white3@boeing.com

Q:

How would you describe your IFPS certification journey?

As exciting and challenging. I obtained most of my certifications through self-study. I would download the study guides and when I felt I was ready, I would let Rickey Rodeffer know so that he could schedule me for a test event.

Q:

Why did you decide to become IFPS certified?

Originally I decided to become certified for the increased knowledge. Shortly after I started getting my certifications, the recession started and talks of downsizing were happening. I decided that I wanted to get as many certifications as I could. I figured that if I got laid off, the certifications would help me get a new job and I’d be able to support my family. When it became apparent that I would not be laid off, my reasons changed again. I then wanted to become the first Master Tech at the Boeing Company. Some others beat me to that. I then decided that I wanted to be the first non-salary employee to become a Fluid Power Specialist. I accomplished that. Now I just take any new certifications that are offered.

Q:

Have your IFPS certifications helped you in your current job?

Yes, they have. I feel that the knowledge I have gained from the certification process has helped me become better at repairing the machinery I work on. It has also allowed me the opportunity to start teaching. I have been selected to start teaching in house pneumatic and hydraulic classes.

Q:

Would you recommend other professionals to become IFPS certified?

I feel that the IFPS is important because by being certified it shows prospective customers and employers that we have taken the initiative to gain more knowledge. www.fluidpowerjournal.com | www.ifps.org

“I Make America” Campaign Promotes U.S. Manufacturing Jobs

T

he Association of Equipment Manufacturers (AEM) and Mike Rowe, creator and host of Discovery Channel’s “Dirty Jobs,” joined forces in Washington, D.C. in September 2010 for the launch of “I Make America,” a national grassroots campaign to promote U.S. manufacturing jobs through infrastructure investment and passage of export agreements. Infrastructure investment and export agreements are proven ways to create and sustain jobs for U.S. workers.

According to a recent poll conducted by Clarus Research, a majority of all voters (53%) said they think “worse” of the economic stimulus package, when they found out that only 3% of its funding was dedicated to rebuilding highways, roads, and bridges. Yet, a strong majority (66%) believes “Given current economic conditions, it’s a good time to build and repair America’s roads and bridges.”

“America’s infrastructure is the connective tissue that keeps society out of the ditch,” said Mike Rowe, an advocate of the trades and founder of the Web site www.mikeroweworks.com. “Our roads, railways, runways, and the stuff we can’t always see, are falling apart around us. Fixing the infrastructure is a job that will have no end, but if we don’t get started, it’ll be the end of us.”

Since 2001, more than 4.7 million manufacturing jobs have been lost. “I Make America” is a resource for workers in the manufacturing industry, as well as the businesses that rely on them and the communities they support, to send a message to Congress that we need new manufacturing policies that will create badly needed jobs now.

The message of “I Make America” is that America needs a new manufacturing policy that creates jobs by doing two fundamental things: · Generating economic activity by rebuilding and modernizing America’s infrastructure—roads, bridges, sewer, clean water, and flood control systems · Helping our farmers and manufacturers create more jobs in the U.S. by exporting their products to new markets around the world “We need to drastically increase American manufacturing jobs so our economy can compete with other countries and our equipment manufacturers are able to prosper and grow right here in the United States,” said AEM President Dennis Slater. “Until these things are done, America’s economy will suffer and our competitive position in the world will be threatened.”

The “I Make America” Web site (www.imakeamercia.com) highlights the disproportionate job losses in the equipment-manufacturing sector and related industries and provides facts on benefits to American prosperity from supporting policies that protect and grow this industry. Additionally, short videos from employees and small business owners around the country tell real-life stories of how manufacturing affects the national economy at www.adayinamericanlife.com.

January/February 2011

The situation seems to cry out for an accumulator, and I’m watching some of you reach for your pens so you can jot down my e-mail address to offer us your services. I appreciate that, but it is not that easy. We are trying to save energy and reduce complexity. The various functions use pressures ranging from 40 bar to 125 bar, and there is a requirement that our pump pressure not exceed 140 bar.

If this were a pneumatic system, it would be no big deal. We would automatically think of sizing the compressor for the average flow and then put on a receiver to store the energy during the dwell times. Because of the way we store and release compressed air, we would use only the air molecules necessary for the job. Even if we store the energy at substantially higher pressures than required for the loads, the proper use of pressure regulators would mitigate the energy loss.

But this is a hydraulic system. If we store the energy in a common gas accumulator with a maximum pressure of 140 bar and a minimum pressure of 125 bar, we would need a gas volume 15 times greater than the available fluid volume. When the load requirement is only 40 bar, the 100-bar differential would be lost in heat. If we were to use weighted accumulators, we would reduce the accumulator volume, but we would still have to deal with the varying pressure requirements and the 100-bar pressure differential lost as heat during the low-pressure portions of the cycle.

This brings us to the title of the article. The most efficient fluid power system is the one where the flow and pressure exactly match the load requirements.

When we store hydraulic fluid in an accumulator, whether gas, spring, or weighted, almost by definition, we will waste some energy as we release it, restricting either the flow or the pressure or both.

When we use a pressure-compensated or load-sensing pump, our pressure setting or our differential pressure setting will be higher than the load requirement and we will waste energy. Our flow will match the speed, but our pressure will be higher than the load requires. To be efficient, we need to use all the stored or induced energy for useful work. What we do not use for useful work we will lose in Btu’s. Use it or lose it.

A couple of articles ago, we discussed the fact that we have an advantage when it comes to alternative energy systems because we have the ability to store energy in ways that no mechanical system can match.

Our weakness is in the wasteful way we typically release that energy.

We put energy into a fluid when we push it against a resistance. That resistance could be a load we are trying to move, a restriction such as a flow control valve, or, if we are storing the fluid for future use, the resistive load of an accumulator. When we take a volume of fluid out of storage, it has a potential energy based on the pressure under which it was stored. When we use that volume of fluid to do some work, we direct the potential energy to the load. Because of the relative incompressibility of liquid, the only variable in the energy equation is the pressure. If the load requires more pressure than is available, no work is done. If the load requires less pressure than is available, work is done and the remaining energy is lost in heat. www.fluidpowerjournal.com | www.ifps.org

What we should try to do is use all the energy in the fluid to do useful work regardless of the flow and pressure requirements of the load. If we can take all the energy in a stream of fluid and do useful work regardless of the initial pressure, we will be able to make some very energy-efficient systems.

I am suggesting, for want of a better term, a variable hydraulic transformer that matches the available pressure and flow to the required pressure and flow. It is simply a variable displacement hydraulic motor coupled to a fixed displacement hydraulic pump as in the circuits below.

Some of you are going to want to stop reading right now because it is going to get technical, but give it a shot and at least try to get the concept. Get out your calculators and check my math to see if it all makes sense. Forget the fudge factor, reject the rule of thumb, and shun the shortcut. Do the math.

This is how it would work: we will have the variable displacement of the motor controlled electronically. A flow transmitter would be placed in the pressure line from the pump, and its setting is what would determine the displacement of the motor. No matter what the load pressure was, the motor would be commanded to drive the pump at an RPM that would produce the required flow.

The motor must develop enough torque to drive the pump, and so the motor output torque will be the same as the pump input torque. Torque is a factor of the pressure and the displacement. If we call the available pressure from the accumulator P1, the motor displacement D1, the load pressure P2, and the pump displacement D2, then P1 x D1 = P2 x D2. For any given flow and pressure requirement from the pump, there will be a discreet displacement required from the motor based on the available pressure.

Let’s walk through an example. We have a pump with a displacement of 83 inches, and we are asking it for a flow of 18 gpm at a resistive pressure of 1400 psi. The energy source for the system is an accumulator loaded to 2000 psi. We know that torque equals the pressure times the displacement divided by 2π (T = P x Disp / 6.2832) and that the flow equals the displacement times the RPM divided by the number of cubic inches in a gallon (Flow = RPM x Disp / 231). Doing the math, 18 = RPM x 8 / 231 and solving for RPM, our pump will have to rotate at about 520 RPM and will need an input torque of… anybody what to jump in here??

Ok, you with the IFPS shirt (available at the IFPS

Store), what have you got? That’s right! 1400 x 8 / 6.2832 = 1,783 in/lb of torque.

So, what will be the motor torque? Right, again!

The motor torque has to be the same as the pump torque so it will be… 1,783 in/lb. What will be the displacement of the motor? Remember the formula: 1,783 = 2000 x D / 6.2832 and solving for D we find the motor displacement to be 5.63 in. Some of you may also have noticed that the ratio of the displacements of the pump and motor is the same as the ratio of the load and available pressures.

However, the controlling flow transmitter is not looking at the pressure, only the flow. If the flow begins to exceed the command setting, the control will cause the motor displacement to decrease to where the motor is just able to maintain the necessary torque to maintain speed. If the flow drops below the command setting, the control will cause the motor displacement to increase, maintaining speed. As the accumulator drains down or as the load increases, the flow transmitter will direct the motor displacement to increase to maintain speed.

The motor displacement will always try to match the available pressure to the torque requirement of the system. It will also become the flow control matching the motor RPM to the pump flow. All the available stored energy will be used for work, and the only losses will be from the relative efficiencies of the components.

In the table and circuit below, you will see three different pressure scenarios. The first is what is described above. The next two show what happens when the input or output pressures change. Notice that the pump and motor HP is the same for each scenario.

Use it or lose it? Let’s use it.

Evaluating

By Dave Ebert, Product Manager, Parker Hannifin Corporation, Hydraulic Pump Division

Hydrostatic

Transmission

System Pumps

for High Horsepower, Heavy-Duty Closed Circuit Applications

H

There are two general hydrostatic transmission configurations: split or closed coupled. Integrated (or closed coupled) transmissions are designed to have the hydraulic pump and motor share a common valving surface and are typically used in light-duty applications.

Split hydrostatic transmission systems (Fig. 1) consist of a power unit with the hydraulic pump, heat exchangers, filters, valves, and controls mounted on a reservoir. The hydraulic motor is remotely mounted and connected to the power unit through hose or tubing. Split transmissions are widely used in heavy- and severeduty closed circuit applications such as shredding, logging, and oil drilling as well as land and sea military equipment because they provide wide flexibility in configuring the system for the most efficient use of space or best weight distribution.

Closed hydraulic circuits typically utilize a variable displacement pump and fixed motor. This combination provides a constant torque output at a fixed maximum pressure over the pump’s full speed range. Speed and direction are controlled with a variable displacement over-center pump. Power from overhauling loads is regenerated back into the pump prime mover. Motor speed is limited to the maximum speed permitted by full pump displacement.

The decision as to which and what type of power unit design to use in a split hydrostatic transmission configuration depends in large part on how severe the demands will be for the intended application. Example: shredding anything from cars to tires, scrap steel, wood, and hot water heaters is an extremely harsh operating environment for a hydraulic pump. Here, a very fast compensator is important that can handle the rapid pressure spikes and rapid pressure decay of these operations. Some pumps can handle massive pressure spikes with ease, while others have difficulty.

Fig. 1: A typical split closedFor high-horsepower, heavy-duty applications, it circuit hydrostatic transmission is important to carefully evaluate five pump design configuration for high horseapproach areas, specifically, the pump’s shaft and power, heavy-duty applications. bearing design, valving and valve packages, controls and control options, oil replenishment pump, and the hot oil shuttle option for closed circuit applications.

ydrostatic transmission drives have long been recognized for superior power transmission when variable output speed is required because they provide fast response, maintain precise speed under varying loads, and allow infinitely variable speed control from zero to maximum.

Most important, they feature a continuous power curve without peaks and valleys and can increase available torque without having to shift gears as is necessary with mechanical gear transmissions.

A hydrostatic transmission is an entire hydraulic system in a single package— pump, motor, and all required controls. These systems provide all of the advantages of a conventional hydraulic system: • Step-less adjustment of speed, torque, and power • Smooth and controllable acceleration • Ability to be stalled without damage • Easy controllability Reservoir Filter Cooler

Shaft and Bearing Design The majority of pump designs utilize conventional bearings at each end of a heavy, large-diameter shaft to support the loading. An alternative approach utilizes a bearing centered around the barrel. The position of the bearing was determined relative to the summation of the internal rotating group forces at one point in the barrel. With the bearing centered at that point, the barrel bearing takes the radial loading, eliminating the need for conventional large pump shafts and support bearings.

Because the radial loads generated from the rotating group are supported by the large barrel bearing, a smaller diameter main shaft can be employed.

This design permits use of a smaller main shaft with the pistons grouped tighter to the center. With a smaller diameter piston bore circle, the piston and fluid velocity is reduced, allowing the pump to run at higher speeds without risk of losing the oil film.  Selection key: Overall, the pump’s design can play a key role in how well it can handle higher operating speeds and shaft/bearing loading.

Valving

Controls

Most closed-circuit pumps will operate in conjunction with multiple valves, providing relief functions along with pressure compensation.

How those valves are arranged and positioned in or on the pump will vary depending on the pump design.

One approach incorporates all valving into a single block (Fig. 2) that can be quickly changed out and replaced with a new one should there be a problem—such as system contamination causing blocked orifices and/or sticking poppets. Other designs, depending on the location of the problem, could require an extended system shut down to troubleshoot and fix the problem.  Selection key: Carefully check the pump’s valving arrangement in light of the intended application and what the time and cost considerations would be to deal with a downtime problem area.

Pump manufacturers generally have only option is to rotate the pump 180 control options to fit virtually any degrees, which also changes the port application requirement. These include configuration.

This changeout feature avoids the "A" Side expense of having to purchase a different pump to fit the new application requirement.

Another consideration is control location. Some pump designs permit control mounting on either side of the pump.

Others designs generally limit control mounting to a specific location.

In such instances, the Electro-hydraulic

Control ("B" Side)

Oil Replenishment When pressure in the pump’s main line drops below the required replenishing pressure, an auxiliary pump is used to provide for the makeup oil.

In some pump designs, this auxiliary pump is externally mounted. Other designs incorporate the auxiliary pump inside the main pump body (Fig. 4) along with the necessary check valves for bi-directional operating. This design approach reduces the overall pump envelope and simplifies component and circuit complexity.

The built-in check valves are ideally suited for proper replenishment in applications such as shredding and drilling. The replenishment of fluid

into the system is especially critical during high dynamic loading conditions where main line pressures can switch from one extreme to the other in a matter of milliseconds.  Selection key: Some pump or system designs utilize conventional check valve configurations for oil replenishment, which are slow to operate and have higher-pressure drops.

Others use a ring check approach that permit high flows and react very fast due to their low mass.

Recommended for closed-loop applications, hot oil shuttles can be mounted on the pump or motor to remove hot oil and allow the transfer of cool filtered oil into the loop. This prevents the same oil from continuously circling the loop. For example, if the oil-replenishing pump is capable of providing 12 gpm, and 4 gpm is lost to leakage, there is an 8-gpm excess of replenish oil. Without the hot oil shuttle, the excess 8 gpm of replenishing oil will spill across the replenishing relief valve and generate heat.

With the shuttle, anytime a pre-set pressure differential is created from one main line side of the system to the other, the valve shifts so that the excess replenishing oil mixes with the low pressure side of the circuit and goes back into the reservoir through the filters and heat exchangers that are part of the system.  Selection key: Built-on shuttle options are ideal to eliminate unnecessary hoses, leak point connections, and simplify the overall hydraulic circuit.

An introduction to

Slip-In Cartridge

Valves

Part

On e

ydraulics involve the use of fluid under pressure to control the velocity, direction of movement, and force of various kinds of mechanical and electro-mechanical devices, such as hold-down clamps, presses, grippers, injection molders, and conveyors. The efficiency with which these devices operate is directly affected by the efficiency of the hydraulic systems that power them. These hydraulic systems consist of components such as pumps, reservoirs, filters, valves, actuators, and fluid conductors such as tubing, hose, or pipe. The movement of the fluid through a hydraulic system is directly controlled by directional control valves, flow control valves, and pressure control valves, which act independently or in conjunction with one another to regulate the flow of fluid. Conventional hydraulic systems are typically constructed with the individual elements plumbed together by means of the pipe, tube, or host (Fig. 1). Identifying flow paths and isolating individual components for the purpose of diagnosing faults is not overly challenging to the trained troubleshooter, as the flow paths are readily inferred by the experienced fluid power technician.

The conventional means of hydraulic control where the individual circuit components are inter-connected by pipe, hose, and tubing has an alternative in modular systems. While conventional valve systems in hydraulic circuits have served industry well over a number of years, the search for better and more efficient methods of construction resulted in the development of modular control systems. Hydraulic circuits employing conventional valves are economical in limited production low-flow circuits, but modular control systems offer economy, reduction in system envelope size, grouping of control functions, fewer connections that result in lower assembly labor cost, and a reduction in external leakage points, etc. The quest for better control systems has resulted in the modular building-block approach to implementing hydraulic controls. Modular control systems are available in three forms, which use manifold blocks to reduce labor content in building hydraulic circuits: stack valves, screw-in (threaded) cartridge valves, and slip-in cartridge valves.

Stack valves (also known as “sandwich valves”) are adaptations of conventional valve interfacing, which allows for the vertical or horizontal stacking components (Fig. 2). The manifold blocks for sandwich valves are typically standard, off-the-shelf building blocks with which circuits may be constructed. Sand-

wich valve circuits can be more compact and have a simpler design at lower cost than circuits utilizing conventional valves due to the fact that most of the valve-to-valve plumbing is accomplished through passageways bored in the valve blocks.

With the pump flow and tank connections supplied to the subplate manifold block, external plumbing is often only required to the pump, reservoir, and the actuators themselves—via the A and B ports. These stackable valves present a challenge when used to build complex circuits and are somewhat limited in their application.

Typically one stack is employed per actuator, with up to eight stacks per standard manifold. Screw-in cartridge valves are often used as the valve element in DO-3 and DO-5 (NG 6 and NG 10) sandwich blocks.

Screw-in and slip-in cartridge valves typically employ custom-designed and custom-manufactured manifold blocks that are limited to a particular application or function. With these custom-manufactured manifold blocks, circuits can be more compact than those put together with conventional hydraulic valves due to the fact that most of the valve-to-valve plumbing is replaced by passageways machined in the blocks.

Aluminum blocks are typically employed at operating pressures up to 3000 psi (200 bar) and malleable steel manifolds where pressures exceed 3000 psi.

The valves are relatively inexpensive due to their modular design. In small-volume production runs, when built in low quantities, the design and manufacture of the custom manifold blocks becomes a major portion of the overall system cost. As the production volume increases, the cost of production of the block itself decreases. For complex machine controls, several manifold block modules can be combined.

Screw-in cartridge valve blocks (Fig. 3) are primarily applied where flow requirements are less than 70 gpm (265 lpm). The screw-in cartridge valves, as the name implies, screws into standardized threaded cavities bored out in a manifold block.

This article will focus on slip-in cartridge valves (SICV), which is a technology that has its origins in Europe in the 1970s. As a result of its origin, the valves and manifolds typically follow ISO and DIN ratings and standards.

Slip-in cartridge valves offer significant improvement over conventional hydraulic components: · Higher efficiency · Modularity in component design · Compact circuits · Minimal internal leakage · Easier component replacement · High flow capability · Rapid valve response · Low valve pressure drop · Low sensitivity to contamination · Greater reliability

A slip-in cartridge valve mainstage is a two-port poppet valve inserted into a cavity in a manifold. A typical valve consists of a sleeve, poppet, and spring inserted into a manifold cavity. The poppet moves within the sleeve to control flow through the valve.

The insert parts are held in the manifold by a cover plate that contains pilot flow passageways to control the poppet. O-rings and backup rings seal the cover and insert sleeve at the manifold bore.

The Major Components of a SICV Circuit The Manifold Block: This block houses the cartridge valves, provides connecting passageways from valve to valve, passages to pilot control valves, pump flow and reservoir return lines, and passages leading to the pilot control valves.

Cartridges: These form the mainstage of a valve— hydraulically controlled poppets with two working ports and one pilot port. The elements of the cartridge consist of a poppet, a sleeve (bushing), and a bias spring.

Pilot Valves: The function of the pilot valve is to control the slip-in cartridge valves, which essentially form the mainstage portion of the valve. Pilot-directional valves are typically DO-3 or DO-5 interface conventional valves or may be screw-in cartridge valves. The slip-in cartridge, then, becomes a mainstage of a valve whose operation and function is determined by the pilot valve.

Covers: The primary function of the cover is to enclose the poppet, spring, and sleeve in the manifold cavity. It is also used to provide control of the poppet, either through orificed plugs contained in the cover or by providing connections to pilot-control valves. The orificed plugs, as shown in Fig. 4, are typically remov-

About the Author: Jim Popovich, CFPAI, CFPPS, CFPHS, was a senior training instructor for a hydraulic manufacturer for 10 years, conducting formal and custom training classes for engineering, sales, maintenance, and distributor personnel.

He currently teaches automation technology classes at Washtenaw Community College in Ann Arbor, Mich.

able in the standard cover with the use of a hex key wrench and are sized to obtain the desired opening and closing speed of the poppet. The goal is typically to maximize the response of the cartridge while minimizing system shock due to the rapid opening or closing of the poppet. In many cases, the cover acts as a connecting block between the pilot valves and the mainstage.

Fig. 5 illustrates a directional valve interface cover onto which a pilot directional valve is bolted.

The size of the cartridge refers to the diameter of the port opening at port A of the poppet (Fig. 6), typically sized in millimeters, with the standard sizes being NG16, 25, 32, 40, 50, 63, 100, 125, and 160.

The flow ratings for the size 16-mm to 160-mm ranges from 32 gpm to 4000 gpm (120 lpm to 15,100 lpm) at a valve pressure drop of 3.5 bar (50 psi).

Additional economy in circuit design can be achieved by matching the individual cartridge elements to the flow requirements determined by its location within a hydraulic circuit.

A slip-in cartridge valve graphical symbol depicts the areas of the poppet that are active at each port.

Pressure applied to either of the main ports exerts a force on the poppet to move it off its seat, allowing flow through the valve. If pressure is applied to the AP area, a force is created to close the valve.

Common area ratios used in slip-in cartridge valves are 1:1 and 1:2. The area ratio corresponds with the ratio of the A port area to the AP area (A:AP). (Note: This article will use this approach to designating area ratios, although some manufacturers use AP:A or even B:A.) Some organizations and manufacturers designate the AP area as F. Part Two of this article will look at how the construction of SICV systems and poppets contribute to a reduction in internal and external leakage. It will also examine different poppet area ratios as applied in pressure control and directional control applications.

Motion Controller Communication Option Delta Computer Systems, Inc. PROFINET IO has been added as a communication option for RMC motion controllers offered by Delta. Customers now can choose options such as PROFINET IO, PROFIBUS DP, EtherNet/IP or many other protocols for communication to PLCs and other systems. PROFINET IO has a much broader reach than PROFIBUS DP and can enable better networking plant-wide. Both are industry standards with PROFINET IO delivering the convenience of Ethernet at rates of 100Mbits/second to exchange data while PROFIBUS DP communications does data exchange with PLCs at up to 12Mbaud. PROFINET IO also connects distributed I/O to PLCs with an easy configuration set up process similar to the PROFIBUS DP. In motion control applications, PROFINET IO is used for fast (millisecondslevel) cyclic data exchange between IO-Controllers and IO-Devices and for acyclic data transactions used for large blocks of configuration data, such as CAM table data to Siemens’ S7 PLCs. www.deltamotion.com

Associationnews CCEFP | The Center For Compact And Efficient Fluid Power

Your AssociAtion’s Helping HAnds Whether you are just getting started, or overwhelmed by a mountain of work, IDP Association Management can show you what a small, specialized staff can accomplish…

big results.

CCEFP’s Focus on Wind Power Gaining Momentum Insuring a place for fluid power in wind power technology is the latest example of the CCEFP’s reach toward realizing two of its central visions: reducing our nation’s energy usage and increasing the ways in which fluid power can improve our quality of life.

Wide-scale use of wind as a power source is rich with potential, but because the generation of wind energy requires power and weight levels that are much higher than typical fluid power applications (500 kW-5 MW), both CCEFP-related research and teaching are vital in efforts to fully exploit this opportunity.

New research and reaching initiatives prove the point. Though centered at the University of Minnesota (UMN), headquarters of the seven-university network, three recently launched research projects stretch beyond this campus by involving additional university, government, and industry partners in Center-specific as well as associated research. An $8-million grant to UMN from the Department of Energy for wind power research has led to the formation of an industry consortium (EOLOS), which will help in accelerating the study. Central to the project will be the experiments on an instrumented 2.5 MW Clipper Liberty wind turbine at the University of Minnesota facility at UMORE Park in Rosemont, Minn.

On another research front, CCEFP Co-Direct Perry Li has just been awarded a $2-million National Science Foundation (NSF) grant to study energy storage for wind power. Other partners on the grant include two former CCEFP researchers, Eric Loth of the University of Virginia and Jim Van de Ven of Worchester Polytechnic Institute, and Lightsail Energy, an energy storage company in Oakland, Calif. CCEFP Director Kim Stelson has received a seed grant to study hydrostatic drives for wind transmissions and is now actively seeking industry partners to form a consortium. Teaching next generations of engineers about the possibilities for fluid power is central to CCEFP’s work, too. As one of many new classes now offered with this emphasis, a graduate-level course dedicated to the study of wind power has been introduced at the University of Minnesota.

Nucor COO to Address Fluid Power Industry Leaders at NFPA’s 2011 Annual Conference

N

ational Fluid Power Association (NFPA) is pleased to announce that Nucor Chief Operating Officer John Ferriola will be the keynote speaker at the 2011 NFPA Annual Conference. He will address more than 100 industry leaders and member companies in Bonita Springs, Fla., February 16 – 19, 2011. Conference details can be found at www.nfpa.com/ac11.

During his keynote address, The Importance of American Manufacturing for Global Strength, Ferriola will provide NFPA members with an overview of Nucor, including its products and culture, a general review of the domestic and global economic environment, and forecasts for the industry. As part of his presentation, he will stress the importance of American-based manufacturing for global strength.

The conference lineup also includes the following speakers: Alan Beaulieu Economist and Principal, Institute for Trend Research U.S. and Global Economic Trends Beaulieu is a favorite presenter at NFPA’s Annual Conference and makes regular appearances at the NFPA Industry & Economic Outlook Conference.

He consults and advises companies throughout the United States, Europe, and Japan on how to plan for and prosper through the business cycle. He will present his typically insightful forecasts for the United States and for economies around the world, with a special focus on fluid power end use markets here at home and in other countries.

William Copacino President & CEO, Oco, Inc. The Strategic Imperative to Manage the Supply Chain Supply Chain Management has a larger impact on costs, revenues, and profitability than many companies realize, and it will have a greater impact in the future, as fuel and transportation costs will invariably increase substantially over the long term and customer demands will also increase. Copacino will comment on the environmental trends that will drive a need to better manage supply chain and will discuss ways companies are preparing to address this challenge.

Ted Gerber Senior Consultant, Guttman Development Strategies Building High-Performing Global Teams Building high-performing teams in today’s environment is challenging, but building them within 52

January/February 2011

a global context is especially difficult. Gerber will describe how to integrate individual differences in values, talent, temperament, and communication style across different cultures and vast geographical distances. He will also relate how high-performing leaders and teams align, manage conflict, and redefine accountability within a global setting.

This year’s conference theme, “Competing on the Global Stage,” will include numerous opportunities for NFPA members to network and share knowledge on the ongoing globalization of the fluid power industry. “Our members have a variety of different objectives in this new economy—staying competitive here at home, increasing sales in export markets, and expanding operations in foreign countries,” Eric Lanke, NFPA’s executive director, said. “Because this diversity of membership provides opportunities to learn from each other, unique knowledge sharing activities have been added to facilitate this interaction.” Conference details can be found online at http://www.nfpa.com/ac11.
