You've Come a Long Way Baby, and Still…

I first met you when we were both young. You had already served in the military, and after The War you were put to work helping build our great industrial complex. I watched as you developed in strength and stature, becoming more powerful and versatile. You gained in popularity as people began to recognize your many attributes: your compactness, longevity, efficiency, and reliability. You work so well in explosive situations, and you don’t even mind getting wet.

When I talk about you in school, I like to tell of how fully integrated you have become in all areas of our daily lives. And yet, when your name is mentioned, there are still curious and puzzled looks by most who do not know you well. You have many supporters and advocates, from Blaise Pascal who discovered your unique qualities so many years ago to The Dean (Kamen) of Invention who actively promotes your purpose through his insightful project: For Inspiration and Recognition of Science and Technology (FIRST). This FIRST Robotics Competition has sparked such an interest in grade school and high school students that the Georgia Dome can hardly contain them.

By Patrick J. Maluso, Many organizations and institutions recognize your CFPMHM, CFPS, CFPAI, value and volunteer hundreds of thousands of hours to Western Hydrostatics, Inc., promote, support, and sustain you. Grants and scholarships 2011 IFPS First Vice President are given to generate more excitement and enthusiasm for you. Academic institutions, trade associations, and societies patronize you through activities such as NFPA’s Fluid Power Challenge, Project Lead the Way, and support of the Engineering Research Center for Compact and Efficient Fluid Power (CCEFP). They also promote you through technical research, webinars, marketing, and standards development to assure acceptable product performance levels and interchangeability, not to mention a standard common graphical language. This makes you a real global player.

The International Fluid Power Society works for you on a different level by making training, education, and certification available to individual mechanics, technicians, and specialists. With the recent introduction of online certification testing, providing tests to other countries and in other languages seems like the next logical step to satisfy international demand for quality benchmark certifications. This will really help boost your image as people become more aware of your influence, especially in countries with emerging economies.

They are clamoring to know you more completely. What a great opportunity and responsibility we now have to share our knowledge about you and to assure you are handled safely and appropriately. We can accomplish this by sharing “Best Practices” standards and “Essential Practices” to ensure safe and dependable installations around the world. These tools will provide knowledge and understanding to those who seek to properly apply your principles and precepts.

You’ve come a long way baby, and still you are misunderstood, misused, and neglected in many applications.

Although you may never become a “dot.com” phenomenon or a wildly popular social network, you will always be near and dear to those whose careers you have enabled. We’ll always recognize and acknowledge you as our “Hidden Giant.”

AllaboutAir

Green Air as a Utility I once met a maintenance contractor who was employed by a medium-sized manufacturing firm.

The contractor dedicated a few days each week and responded to all emergencies for the firm. This seemed to be a very cost-effective and efficient approach to routine and preventative maintenance.

In addition, the firm referred management-driven changes, improvements, and expansion projects to the contractor as “cost-extra” responsibilities. In this manner, the firm procured greater expertise for fewer hours than the cost of a full-time employee. Why not buy air already prepared as well?

Compressed air may be one of the most widely used, least understood, and unnecessarily expensive utilities or sources of energy in too many manufacturing facilities. In many cases, manufacturers might be better served if they purchased compressed air similarly to nitrogen but without the bottle or tank that presents an inconvenience. If compressed air were available as a utility like the electricity available at

multiple outlets, it might be more cost effective.

For the moment, let’s assume that 80% of all manufacturing plants could connect to a readily available, almost unlimited* source of compressed air at 80 psig. Manufacturers of pneumatic devices and machines that utilize compressed air energy would tailor their products to a standard that operates most effectively at 80 psig just as the majority of electrical devices run on 120 volts of alternating current. This semi-standardization of the compressed air supply would promote savings and uniformity for devices, suppliers, and users.

For a new industrial park or large new manufacturing complex, it is possible to install a compressed air utility that delivers compressed air from a central source to each and every building in the complex. With generously sized headers run underground in a loop or effective pattern, each building could have access to a compressed air inlet in the manner of electrical mains.

Possibly the compressed air routing might be similar in

pattern to a sewer system if that image is not discouraging. The compressed air inlet pipes could be determined by the number of square feet of floor space or with multiple inlets for larger buildings.

The inlet to each building might have a flow meter and data logger to track and record the compressed air consumption by amount and time of day. At end of day, the inlet valve may be closed to prevent leaks in the plant plumbing from wasting compressed air.

Since this system can be essentially “air on demand,” the large reservoirs that bleed down and waste air overnight may be eliminated. The in-plant com-

pressed air plumbing might also be laid under or within the floor rather than hung overhead. This may keep the plumbing out of sight and closer to the point of use than overhead plumbing with “air drops.”

With a central “air on demand” system, the compressor and dryer equipment may be larger for economy of scale. One 500-scfm compressor or dryer costs less to buy and run than five 100-scfm units.

The inevitable need for higher pressure for some applications may be met by a small, dedicated highpressure compressor.

This dedicated unit would only be required to raise the pressure from 80 psig to 110 psig or whatever the high-pressure requirement. This added SCFM to bring up to higher pressure presents a large potential saving over compressing all of the air up and regulating back down. The central compressed air source could also offer an auxiliary higher-pressure source.

When I wrote “use oversized plumbing” in the January/February issue, pneumatic guru Hank van Ormer from Air Power USA correctly reminded me that there is no such thing as over-sized plumbing with compressed air. Also with the centralized compressed air system, the knowledgeable operator/ supplier could be a valuable source of information, answers, and recommendations The simple diagram included is to stimulate open minds and get creative juices flowing with unlimited ideas.

Create a Mastermind Group

that works for you

You know the scenario all too well: You’re facing a stressful challenge at work, and you’re struggling to come up with new, fresh, and creative ideas to solve the issue.

Nothing you think of on your own seems right. You’re too close to your own challenge to create an innovative solution. Frustrated by your lack of creativity, you decide to sleep on the problem yet another night, hoping the answer will come to you tomorrow.

N

ow imagine that same scenario, but this time you have two or three other people dedicated to helping you work it out. They listen to your questions, they offer their advice, and they help you find solutions.

Then, when your problem is resolved, you turn and listen to theirs. This is the essence of a mastermind.

A mastermind is a small group, usually three to five people, of dedicated peers who share and support each other through the challenges of life and leadership. It provides a mutually beneficial source of inspiration, information, and collaboration for all of its members. Far more than a typical network, a mastermind is your inner circle—your “A” team.

Realize that a mastermind is very different from a networking group, a professional association, or a common interest group. While these types of groups serve important purposes for leaders, that’s not the focus of a mastermind. Rather, a mastermind is a group so cohesive that the members operate as one, focusing exclusively on the needs of one member at a time, and then another, and then another.

Masterminds can be as varied and extraordinary as the leaders themselves. For example, one group might consist of three consultants who meet once a week for an hour to grow their businesses, while another group might include six investors who meet once a month for an hour to make investment decisions.

Another could involve seven small-business CEOs who meet once a quarter for two hours to set goals, or five executive officers who meet twice a year for a full day to strategize, or even eight former-businesswomen-turned-“mompreneurs” who meet on an ongoing basis via phone and email to answer questions and share resources.

Many leaders thrive with the support of their masterminds. They discuss business results, leadership challenges, goals and visions, individual and organizational strategy, and more. The support is practical, personal, and tailored to each member’s unique characteristics and concerns.

Suggest It.

By Dr. Joelle K. Jay

If creating a mastermind sounds like just what you need to take your business or career to the next level, consider the following six steps of mastermind creation.

Mindmap It.

1

Brainstorm. What do you hope a mastermind will help you do? Provide objective advice? Be a sounding board? Hold you accountable? Having a good sense of what you want from the group will help you create it. Put your ideas onto the page in any order—a mindmap—just to explore the possibilities.

Arrange It.

2

Who will help you achieve your purpose? The most important element of a mastermind is the people.

Arrange the mastermind so it’s made up of the most powerful team. As you consider the possibilities, remember to look for people who are different from you. Diversity is one of the advantages to a mastermind. Your mastermind will help best if their perspective is different from yours.

3

Once you have some names, extend the invitation.

A phone call, an email, a meeting, a conversation over lunch—however is most comfortable for you, share your idea about the mastermind and see who’s interested.

Not everyone understands what a mastermind is, and not everyone wants to join one. That’s okay. You’re not looking to strong-arm anyone; you’re looking for people who are drawn to the idea. A mastermind that doesn’t form naturally can be difficult to sustain. Take it easy. Float the idea. See what the response is and move forward with the partners who emerge.

Try It Out.

4

Once you have found people interested in joining your mastermind, get together. Hold an informal meeting to get to know more about each other and what your mastermind could be. To get the meeting started, reiterate what a mastermind is, how you envision it unfolding, what you would hope to get out of it, and why the people you’ve invited seem to be a good fit. Then go around the room one person at a time and see what they think. Here are some questions to ask: • What interests you about forming a mastermind?

• What characteristics would be important to you in this group?

• What would you be hoping to achieve?

By the end of the meeting, your goal should be to determine who, specifically, is interested in formally committing to your mastermind group at this time.

Then you can set a date for your first meeting. www.fluidpowerjournal.com | www.ifps.org

Establish It.

5

The first time your mastermind meets as a group is an important day. You will be establishing the tone for your time as a team. You will get off to a good start if you take the time in the first meeting to do it well.

Following a formal agenda will help. Some things to include in your agenda are • A welcome message • Foundational questions: »» Who are you, what do you do, and what brought you to this group? »» How can this group support you in the best way possible? »» What gifts and talents do you bring to this group? »» What ground rules would make our time together worthwhile? »» What else do you want us to know?

• Review logistics: »» How often will we meet? »» When? »» Where? »» What will the format be?

• Closing thoughts However you structure your meetings, make sure each member has the opportunity to discuss their goals, needs, and next steps. With these three elements, each member is sure to move swiftly in the direction in their vision.

Regulate It.

competent leaders share similar struggles as you, and they can offer a unique and objective perspective to whatever challenge you’re facing. After all, when it comes to problem solving, two (or more) heads are always better than one. Ultimately, your mastermind will help you become a better leader and enhance your quality of life by making you feel connected to other leaders. When you avail yourself to other people and think about how you can help them, you will naturally help yourself.

6

When a mastermind group is planned thoughtfully by people who are dedicated to each other and their goals, it can be one of the most beneficial forms of support a leader can get. But masterminds can also get off track. You will protect the effectiveness of your mastermind by keeping your finger on the pulse of the value it provides each member with a little selfinitiated regulation.

At the end of every mastermind—or at least occasionally—go around the table and ask this question: “On a scale of one to ten, ‘one’ being low and ‘ten’ high, what was the value of today’s meeting for you?

Why?” Then talk about it. What would the group have to change to make it a “ten?” What would you personally have to change?

Assessing your mastermind this way gives members the chance to ask for what they need from the group and to take personal responsibility for anything they’re doing to hold back the mastermind (and themselves). It also gives the group the chance to grow and evolve to become the best possible opportunity for all of the members to get the support they need.

Gain Your Edge Regardless of your industry, business, or profession, you shouldn’t have to go it alone. Many talented and circle 325 www.ifps.org | www.fluidpowerjournal.com

New Problem:

previous Problem: Tire Pressure (from Systems Integrator Directory issue)

Many times you may have heard of the comment, “Have you put winter air in your tires?” Well, there may be some truth to that statement.

Here is your question. If you last checked your car tires at 80°F and measured 35 psi, and now the temperature has dropped to 20°F without any loss of air, what would the tire pressure now be?

Give your answer to the nearest whole number.

MBS 1350 – Dual Output Equals Extra Versatility In the mobile construction industry, inexpensive cartridge pressure switches are often used to control hydraulic applications in construction vehicles. But mechanical switches have a relatively short life span, so although inexpensive, the cartridge pressure switches were costing manufacturers money because of warranty claims from their customers. But when a U.S.-based manufacturer, a supplier to the mobile hydraulic sector, heard about the Danfoss dual output transmitter—the MBS 1350—they replaced the mechanical switches it had been using on its machines with the compact transmitters.

A transmitter and switch in one, the MBS 1350 is designed for heavy-duty mobile applications. The dual output transmitter is suitable for correcting and adjusting pressure, force, or torque, according to continuous proportional analog output signal. And the electronic logic switch can be used as a simple on/ off function, for example when the pressure limit is reached, to either start or stop a process on the machine.

The U.S. manufacturer required different output parameters, so Danfoss engineers designed a new board with direct reference to ground and with virtually zero resistance. The switch to ground (STG) makes the transmitter versatile and means it can directly drive the inputs and relays on most controllers installed on a range of vehicles, from back hoes and skid loaders, to dump trucks and mining machinery.

The transmitter is currently being field-tested in a digger application where the switch is activated by the pressure generated by the shovel’s lifting cylinders and a GPS signal from the switch. This gives operators the opportunity to see the load weight, where it was removed from, and where the load was placed, which is very important in operations such as mining. Other applications that are being considered include a dump function, power steering, power brakes, and end of stroke in cylinder applications.

profile data Richard Bullers, CFPPS, is senior applications engineer at SMC Corporation of America. He is a member of the 2011 IFPS Board of Directors.

Richard Bullers

Q:

When and where did your career in the fluid power industry start, and how was it a stepping stone to where you are today?

1978 was the year I stepped off the streets of Indianapolis into a job assembling thermostatically controlled 2-way valves with ITT Hoffman Specialty; Lawler Valves as a member of the local steel workers union. A young engineer inspired me to consider furthering my education, and I started on a tenyear journey of full-time work and part-time study for a degree to advance my career. In 1988 ITT consolidated its operations and moved to Chicago, and I was offered a technical position at a young, but promising company, SMC Pneumatics.

Q:

What is your current job and responsibilities?

As a senior applications engineer, I apply specific mechanical and fluid power engineering skills to solve a variety of problems in pneumatic systems and automated machines. There are a number of different issues that range from the fundamentals of sizing to the intricacies of troubleshooting to directly influencing product development and design strategies. Each day brings a new set of challenges, new and interesting applications, and the opportunity to promote the optimum use of fluid power technology.

Q:

What is the most memorable moment in your fluid power career?

What did it teach you?

Somewhere along the line I must have learned more than I’d forgotten because I was offered the opportunity to train distributors, customers, and new employees in basic pneumatic technology.

During this period, I was able to develop training in industrial vacuum technology as well. The entire experience was mind opening and taught me a great deal about helping others. I had to develop a new skill set to facilitate the learning experience

of people who just wanted to do well in their jobs.

What a better way to become a student all over again than to become a teacher?

Q:

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

This is the most difficult question simply because so many small successes add up to make the body of achievement. When you see the light go on each time a student raises their eyebrows in understanding, when a difficult problem is solved to help keep the wheels turning, when a manufacturing process is perfected that reduces the cost of a product we all use, then the body of achievement becomes an entire career. Being elected to the IFPS Board of Directors has been the capstone.

Q:

How and why did you get involved in the IFPS? Training others about fluid power technology motivated me to get serious about fluid power certification from the International Fluid Power Society. If you’re not a subject matter expert when you stand up in front of a dozen curious minds, it’s like going hunting without any ammunition. The IFPS is a great way to further your education and boost your confidence. The organization proved to be the bedrock of professionalism and the ideal resource for validating my technical competence.

Q:

Why do you feel the IFPS is important?

The Society provides the tools needed for success from technical skill sets to networking with other professionals. In a tight job market, the recognition provided by membership and certification is a valuable

caveat to any resume, but it’s more than that. If you have ever been in the dark with pneumatic circuitry, the mystery of troubleshooting a hydraulic system, or why fluid power issues seem to bring a puzzled look to your otherwise sharp engineer, the IFPS can help.

You cannot do any job without the right tools, and the IFPS has them.

Q:

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

Aside from the benefits I’ve been noting all along, the friendships are the most valuable thing I’ve gained from being an IFPS member. The opportunity to help others, earn their trust, and share in all the ups and downs of this working life has not only provided me with a rewarding career, but also people I can count on.

Q:

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

Ten thousand years ago we discovered farming, and great societies were built upon this technology.

Three hundred years ago, an industrial revolution started and 97% of the population shifted away from agriculture. Today, electronics is merging with the motion technologies of hydraulics, pneumatics, and electrical control to automate the manufacturing base of the world and again change the structure of society.

I look at fluid power as a key part of a new renaissance in changing the social fabric of the world.

This is no idle boast, but a reality. As we move forward automating the dangerous and dull jobs of the past, our resources are set free to focus on meeting our new challenges in energy, health, and the environment. If you are not already a member of IFPS, I hope you will join us for the journey.

The Hydraulic Fluid’s Best Friend

s I’ve explained in previous columns, hydraulic fluid has a BIG job to do. It’s a power transmission device, a lubricant, a heat transfer medium—and even a sealant, in some hydraulic components at least.

This is why I consider the fluid to be THE most important component of a hydraulic system. And certainly not something to be purchased on price alone.

But regardless of whether the fluid used is a synthetic, a high VI maximum efficiency hydraulic fluid (MEHF) ashless, zinc-free, multigrade or monograde—or any other of the myriad of options available today, to do its job well, the fluid needs help from its friends.

The first of these—and possibly the hydraulic fluid’s best friend—is the reservoir or tank.

Size Matters Traditionally, recommended tank size for mineral hydraulic oil has been 3 to 5 times Q plus a 10% air cushion. Where Q is pump flow per minute—or mean pump flow per minute where a variable pump is used.

For some special fluids, recommended tank size is even larger. For example, for hydraulic systems using HFC and HFD fluids, a tank volume of 5 to 8 times Q is recommended.

The above formulas were not devised to sell more oil or to increase the size of the spill risk. They were devised with hydraulic system performance and reliability in mind.

But these days, with increasing demand for lighter, more compact hydraulic equipment, particularly in mobile markets, tank oil volumes of this order are becoming a thing of the past.

16

Off-Highway Directory 2011

This leaves one important function of the tank for If tank oil volume or more precisely, the lack of it, which there is no clear substitute—other than adeaffects hydraulic system performance and reliability, quate oil volume and therefore dwell time. And that then it follows that less than ideal tank volume hogis the release of entrained air. ties the hydraulic fluid.

Air entrained in hydraulic fluid affects the perHow? Well, in order to answer this question, the formance and reliability of the hydraulic system in a traditional functions of the hydraulic tank—and number of ways, including how these functions can (or can not) be subrogated • reduced bulk modulus, resulting in spongy to the hydraulic fluid’s other “friends” in the sysoperation and poor control system response tem—must be considered.

• increased heat-load Beyond its most rudimentary role of providing a store of fluid, the main functions of the hydraulic tank are to Fig. 1: Ideal tank construction for air release. (Source: • dissipate heat; and Industrial Hydraulic Control by Rohner, P. p107) • allow contaminants to settle out of the fluid.

In practice, the amount of heat dissipated from even a large tank is relatively small, so this function is easily and more efficiently subrogated to a heat exchanger.

When it comes to contaminants, the tank’s role in settling out particulate and water can be largely subrogated to the system’s filters. www.fluidpowerjournal.com | www.ifps.org

• reduced thermal conductivity • increased oxidation and thermal degradation (micro-dieseling) of the fluid • reduced fluid viscosity, which leaves critical surfaces vulnerable to wear • increased noise levels • decreased system efficiency I’ve seen a lot of anecdotal evidence over the years suggesting that skimping on tank volume compromises hydraulic system reliability. One example that comes to mind is a hydraulic excavator manufacturer who, after increasing tank size and installed cooling capacity, saw typical pump life increase from 12,000 to 20,000 hours! This reinforces the point that no matter how good the hydraulic fluid is, it needs help from its friends.

No Kinks - No Hose Twisting Simplified hose configuration, less hose and adapters combine to reduce repairs and downtime cutting the overall cost of hydraulics.

Shape Is Important, Too When it comes to releasing entrained air from the fluid, volume and therefore dwell time in the tank is very important, but so too is the way the tank is constructed.

Fig. 1 shows ideal tank construction for air release.

The tank shown has a longitudinal baffle separating the return from the pump intake. Return fluid is made to travel the full length of the tank twice and pass through a diffuser—designed to collect and float off air bubbles, before it re-enters the pump intake.

As an aside, with the tank construction, if the pump was to become noisy, aeration can be eliminated as a possible cause. Because in this tank design, entrained air is “filtered” out by the diffuser. This would leave (vaporous) cavitation as the most likely cause of pump noise because cavitation cannot be “filtered” out.

Note also, the tank design shown in Fig. 1 features an angled bottom plate to better facilitate drain-off of settled contaminants (water and dirt).

Give Your Friends a Hand So if you design or build hydraulic equipment and you care about its reliability (and you should), don’t skimp on tank volume or be cheap about the tank’s construction.

If you service and maintain hydraulic equipment, there is little that can be done – economically at least, about installed tank volume or the lack of it. But you can specify minimum required tank volume when ordering new equipment.

And don’t forget, the tank, like the hydraulic system’s heat exchanger and filters, must be taken care of. This involves regular drain-off of settled contaminants and occasional internal cleaning. Because to do its job effectively, the hydraulic fluid needs a lot of help from its friends.

Sheet

Handling with

Vacuum

By Daniel Pascoe

all the product types that are difficult to pick up, thin sheet handling is one of trickiest to undertake for the vacuum user. Sheet handling is very common and found throughout industry in sheet metal fabrication, paper printing, wood panel production, etc.

The reason it is difficult is not because of heavy weights, cycle rates, or dirty environments. The difficulty is preventing sheets sticking together in a vertical lift. Multiple sheet lifting is at least an irritation for a printing press operation and at worse, catastrophic in a steel stamping facility where multiple sheets are placed in an automated press production line.

This article offers some basic solutions to this problem. As is often the case in good vacuum practice, it is not the component choice but their application that makes for a successful solution.

Depending on the product being handled, various methods are employed. As in most industrial applications, what works for one industry often is not suitable for another. Here I offer an obvious starting point for particular industries with the three previous industry examples being used for comparison.

Paper Handling With printing presses, at one end you have a stack of plain white paper sheet on a pallet, and on the other end, you have a stack of very colorful printed paper on 18

Off-Highway Directory 2011

Fig. 1

a pallet. There are four fundamental things that happen to this paper in its transformation: it is picked up from the first pallet using vacuum, transferred mechanically through the press, ink is applied, and then using vacuum once again, it is placed on the second pallet.

This happens very quickly, with sheets being transported though the printing press at incredible speeds.

Therefore, the accurate pick up and release of the sheets with vacuum cups must be reliable and repetitive.

Vacuum on a web offset press is often generated by what is referred to as a “pressure/vacuum pump.” This electrical vacuum pump generates BOTH vacuum and pressure where the exhaust port of the pump is used for the pressure generation. Vacuum is for vac-

uum pick up, and pressure is used for separating the thin sheets of paper to enable a single sheet lift. In Fig. 1, the vacuum cups are highlighted by arrow “A” and as highlighted by arrow “B,” air nozzles are positioned just below the top layer of paper, which creates separation. The vacuum cups grip the top sheet, and lift and drag the leading edge into the printing press.

At the same time, a bristled brush head is sometimes used to keep other sheets down. Not very technical, but effective nonetheless.

Vacuum cup selection in this scenario is not crucial except that the cups selected must have a flat, wide diameter location surface to prevent deformation of the paper. This is in contrast to the next application. www.fluidpowerjournal.com | www.ifps.org

Wood Panel and Sheet Metal Handling Unlike paper handling as described previously, wood panels are normally very heavy.

They are also very flat. Finished panels also have a very smooth surface. These three characteristics create enormous problems, but the fourth and normally the most problematic to the user is that they are porous—a whole host of characteristics that offer difficulty lifting only the top sheet.

The actual application will determine which of the following methods are the most efficient.

However, the following methods used either by themselves or together, offer a good single panel handling solution. Bellows vacuum cups offer an individual lift feature independent of the actual machinery movement. Therefore, when vacuum is applied, the bellows cup will pull the panel upwards. If you use two separate systems, as shown in Fig. 2, one side of the panel is lifted just before the other. This creates a “peeling” effect, which breaks the seal on one side of the panel.

When circuit two is activated, the panel is drawn vertical with the cups in circuit one.

One of the simplest methods of avoiding vacuum from being drawn through to the second sheet due to the porosity of the wood panel is to use the correct size vacuum cups. Quite often, particularly on wooden panels, vacuum cups in the region of 150mm diameter (6-in.) are used. Each of these cups offer in excess of 200 lbs per cup at 20"Hg. The smaller the diameter the vacuum cup, the less surface area and consequently the less air “drawn” through the top layer. For example, a 2-in. diameter vacuum cup at 20"Hg offers 30 lbs at 20"Hg. Ten of these, of course, will handle 300 lbs, more than enough for a 8 ft x 4 ft wood panel.

There are certain vacuum cups that offer a pressure ring within the vacuum cup itself. Fig. 3 shows a cut-away view of a cup that uses two O rings as the vacuum seal. Compressed air is blown through the central area at the same time vacuum is applied to the outer ring, “pushing” the panel underneath, away from the top sheet. However, this method requires more control equipment, and less choice of manufacturers are available to the vacuum user.

Handling metal sheets has the same issues experienced in handling wooden panels. Porosity is not a characteristic when handling steel, however, but an

Fig. 3

oil film often is. The oil used to in steel storage or production creates a large problem when vacuum cups are used for handling the sheets from a pallet.

In most applications, a dual circuit (circuit A + B) as described above is very effective. Users often use a mechanical separator, such as a sprung steel “finger,” that traps the second sheet when the top sheet is lifted. The correct vacuum cups are crucial in this application. Ones that are flat offer the best solution, as large bellows cups (often found in the stamping industry) create a deformation just underneath the first steel sheet, which itself creates a “vacuum cup” as it is pulled into the center of the large bellows cup. Bellows cups are popular in steel stamping as they are good at deforming to curved surfaces. However in de-stacking operations, flat cups should be used.

Consideration should be made to vacuum level, flow rate, and in particular, machine movement when handling thin sheet products. This article offers basic fundamentals, but of course each application is different offering its own set of unique problems. The methods described here offer a good starting point for handling one sheet at a time….every time.

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. circle 332

Wave Spring

Springs  Wave Rotor Clip Company, Inc.

Valve Box Schunk Inc. The compact valve box is directly attached to the PGN-plus gripper and helps to increase actuation speed by up to 100%. In the case of a conventional pneumatic solution, the compressed air of the feeding long air supply line is lost at each cycle. With the valve box VB, the piston area of the accumulator is immediately filled, resulting in reduced air consumption and shorter cycle times. The compact unit is provided with air and electrical signals through central connections. Long air supply lines are no longer necessary. Sizes for the PGN-plus universal grippers are available from 64 to 160. www.schunk.com

The MST Series Truwave™ single-turn wave springs are available in sizes from 16 mm to 170 mm and are suitable for short deflection applications. Bearing retention advantages include possible overhead assembly, since the wave spring can lightly grip the inside of the bearing bore; automatic installation via a tapered mandrel similar to the automatic installation of retaining rings; even load/force with small tolerances dues to even, sinusoidal waves in the spring design; no radial jamming, since the spring ends are able to overlap and do not push against one another; no tooling cost for special sizes; and self-centering in bearing bore. www.rotorclip.com



Hydraulic-Over-Air Relay Valves MICO Inc. The valves are designed to convert hydraulic modulated input pressure to a proportional output air pressure. They are suitable for on- and off-highway applications, such as controlling an air-braked trailer with a hydraulically braked towing vehicle that has an air power source. The system originates with a hydraulic vehicle component, such as a master cylinder or hydraulic control valve, which delivers a given hydraulic input pressure. This input pressure sends a pilot signal to the relay valve in order to modulate air brake pressure on the other end.

Three designs are available: single, dual, and tandem.

The valves can accommodate a maximum air pressure of 150 psi and maximum hydraulic pressure of 2000 psi.

The valves can be adjusted to operate at anywhere from a 3:1 to 21:1 hydraulic-to-air-pressure ratio. Maximum operating temperature for the valves is 250°F. www.mico.com

Technology Focus

Pressure transducers with Silicon-on-Sapphire (SOS) technology have been commercially used for decades. Some of its well-known performance features are high-temperature operation, high accuracy and repeatability, and long-term stability.

The main markets for SOS pressure transducers have been the oil and gas industry, subsea applications, aerospace, and the defense industry.

Now, SOS pressure transducers will find its way into the off highway industry.

Pressure Transducer for Off-Highway?

Technology Focus

What is Silicon-on-Sapphire?

Sapphire is from the Greek word “sappherios” referring to a naturally occurring gemstone of the mineral aluminum oxide Al2O3. Single crystal sapphire is the purest form of aluminum oxide and is artificially produced by heating aluminum oxide powder in a controlled furnace to more than 3600°F then slowly cooled. The result is an extremely pure single crystal of sapphire that can weigh more than 100 lb.

The sapphire wafer is cut at a specific angle, which allows silicon atoms to bond on sapphire to form SiO2 onto the sapphire wafer in a manner that the growth is an atomic extension of the sapphire itself.

The process is known as “epitaxial growth,” which makes the SOS technology possible.

SOS is formed by depositing a thin layer of silicon onto a sapphire wafer at a high temperature. The doped silicon strain gauges are etched from this layer.

The individual strain gauges are electrically isolated from one another by the insulating characteristics of the sapphire substrate.

The ability to operate at high temperatures, in addition to having the mechanical properties of vir-

Doping to induce more negative areas (N type Si)

tually no hysteresis and chemical inertness, make it ideal for use as a pressure sensor.

Pressure transducers used in modern off-highway machines have to withstand harsh situations like severe pressure spikes caused by valves shifting, prolonged exposure to continual pulsation, broad temperature ranges, shocks, and vibrations. Pressure spikes can be especially harmful or even destroy a pressure transducer easily. Prolonged exposure to continual pulsation can fatigue the pressure transducer and can influence the long-term stability and accuracy.

Due to its performance, the use of the Siliconon-Sapphire sensor technology for the off-highway industry is evident. However, due to this market being very price sensitive, the SOS pressure sensor technology never had a breakthrough in the high volume off-highway market.

Ellison Sensors International, located in Great Britain, has been a producer of Silicon-on-Sapphire pressure transducers for more than 25 years. Its products have a positive reputation in the aerospace, defense, oil, gas, and subsea industries. When German pressure switch and pressure sensor specialist

Insulation relies on the reverse bias PN junction, as temperature rises this breaks down (P type Si)

Diffused Silicon Sensor

SUCO took over Ellison Sensors International, a combined experience of nearly 80 years of pressure monitoring was formed.

SUCO knows as a key vendor to many off-highway OEMs the need for products that can withstand pressure spikes and high rise rates, along with having high accuracy, repeatability, and long-term stability.

Suco recently introduced at the IFPE 2011 in Las Vegas, Nev., its latest pressure transducer Type 07XX based on Silicon-on-Sapphire technology. Key characteristics are • 4 x overpressure safety Pnom • 8 x burst pressure Pnom • max. rise rate <72,500psi/second (<5,000bar/ second) • mechanical life 10,000,000 pulses Pnom • wetted parts stainless steel 1.4305/SAE grade 303/ Titanium This performance was only possible by using SOS technology and will open the door for a new generation of pressure transducers in the off-highway market.

FPDA | Motion & Control Network

FPDA Monthly Economic Indicators Report Shows the Industry on Good Pace The FPDA Motion & Control Network, in conjunction with Cleveland Research Group, conducts a monthly survey of distributor and manufacturer members to assess business conditions. The most recent survey of members showed: FPDA Index Surges to New High–The January FPDA Index produced a reading of 78.3, a notable improvement from the December reading of 64.6. This indicates the fluid power industry expanded at a faster pace compared to December and this is directionally consistent with the broader ISM Purchasing Managers’ index.

The ISM index posted a reading of 60.8 in January, up from the December reading of 57.0, the highest reading since June 2004.

Sales Growth Accelerates–Sales growth among participating FPDA members remains surprisingly robust despite facing increasingly difficult comparisons. On average, members reported sales growth of 32% in January, an acceleration from the robust 28% growth in December.

2011 Outlook Improves Again–The order and backlog strength appears to be driving increased confidence in the sustainability of the ongoing industrial recovery. On average, participants are now anticipating full year growth of 15% for 2011, up from the prior view of up 12%. Within this, manufacturers’ outlook is up sharply to 18% versus a prior view of 10% while distributors are now looking for 13% growth versus prior expectations of 14%.

FPDA is comprised of nearly 200 wholesale distributors and manufacturers of fluid power and motion technology products, as well as product and service vendors to the fluid power distribution services industry. Specific membership criteria and applications may be downloaded from www.fpda.org.

CCEFP | The Center For Compact And Efficient Fluid Power

CCEFP Research

Excavator Outreach

By Micah Olson, 2010 REU Student, Purdue University In Year 5, the CCEFP E&O Program was awarded an additional $10,000 to support the TRIBES-E (Teaching Relevant Inquiry-Based Environmental Science and Engineering) program in the northern Minnesota town of Bemidji. The conference was made up of 25 teachers of Native American students from around Bemidji. Dwight Gourneau, who was born on a reservation and is a retired electrical engineer from Rochester, Minn., has been running this conference annually since 2004, when it got its start. He and Diana Dalbotten pulled off another great weeklong conference in Bemidji.

The CCEFP sent me up to the conference to present one of the Portable Fluid Power Demonstrators, the Micro-Excavator. I am an undergraduate mechanical engineer at the University of Minnesota and spent my summer as a CCEFP REU at Purdue University working on developing the Micro-Excavator. When Alyssa Burger asked me to travel to Bemidji for the conference, I was more than happy to go to beautiful northern Minnesota and present the MicroExcavator and the curriculum for it, written by RETâ&#x20AC;&#x2122;s at Purdue University, Brian Bettag and Gary Werner.

The Micro-Excavator is an excavator arm scaled down to about 3 feet in length and powered with water with a 70-psi pump and controlled by four valves and cylinders. It is mounted on a 17-gallon tank, which is used as its reservoir. While the first ones used manual While current noise levels in industrial applications are often tolerable, if fluid power systems are to be used in homes, hospitals, or in devices worn on the body, this noise must be greatly reduced.

Noise has been specifically identified by the Center for Compact and Efficient Fluid Power as a major technical barrier to both broadening the use of fluid power in traditional applications and to using fluid power in more noise-sensitive environments. Whether it is hydraulics or pneumatics, the high forces involved in transmitting power using fluids induces vibration and noise. This is often attributed to the source of the power, say, an engine, but techniques for reducing noise in these systems are well known; reduction of the noise produced by fluid power pumps and actuators has not received as much attention. The question of reducing noise in fluid power systems is the focus of work currently in progress in Project 3B.1: Passive Noise Control in Fluid Power.

Project 3B.1 is focused on using passive techniques, such as engineered materials, to make fluid power systems quieter. A prototype hydraulic silencer has been developed to reduce the amount of noise that is allowed to propagate down a hydraulic circuit. The silencer uses a specially designed polymer lining that both reflects fluid-borne noise back toward the pump 48

valves, we have since moved on to electronic valves with joystick controls, and our most recent generation is operated by a microcontroller. The main purpose of the excavator is to be used in high school curricula to teach the basics of fluid power, and with the recent additions, electronics and robotics as well.

The first day of teaching in Bemidji, I began with the fluid power basics, beginning with Pascalâ&#x20AC;&#x2122;s Law and moving on to schematic drawings to show a basic fluid

power system: pump, valve, cylinder, and reservoir. I let the teachers experiment with different size cylinders, different pressures, and different amounts of flow to see how they affected speed and force. Next I had them put back together three of the first- and second-generation excavators from the University of Minnesota that I had taken all the cylinders off of and disconnected all the hoses. This activity really helped them to grasp the whole of the system and let them think about how they could use these in their own classrooms.

The second day, I introduced a generation 4 excavator, which was operated by the Vex Robotics microcontroller. I taught them some programming using EacyC, the language used for the Vex Robotics. They were able to grasp the basics in the little amount of time we had and even programmed a sequence into the excavator to make it do a specified task. The teachers learned the basics of Boolean statements and digital outputs in order to program the sequence.

The teachers were very excited about the opportunities to use the excavators, and they were enthusiastic about learning basic fluid power concepts. Most of them had little to no understanding of fluid power going into it, so I am convinced that they learned a lot. They know that they can borrow the excavators from the University of Minnesota, but it would be best if they could have their own up north with them that they could share between their classrooms.

Hopefully a number of the teachers will incorporate the excavators into their science curriculum. * Reprinted with permission from the CCEFP Winter 2011 newsletter.

Fluid Power Can Be Noisy

By Nick Earnhart, Graduate Student, Georgia Institute of Technology and dissipates sound energy before it gets to the rest of the system. This design showed improved performance against a benchmark commercial off-the-shelf silencer in a non-optimized design of the same size. A theoretical model of the silencer performance was developed to allow engineers to design this type of silencer for a specific application. More advanced integration could include the use of this material directly in a pump or accumulator so a separate device is not needed.

There is another aspect to this research question; that is, how do noise control techniques need to change when the device to be treated is very small?

When the size of a device becomes small relative to the wavelength of radiated sound, classical noise control techniques do not work well. In addition, as fluid power systems become used in more noise-sensitive environments, the fraction of energy that may be allowed to generate sound gets much smaller. These two factors pose significant challenges, hence the focus within the Center to address noise concerns.

There are two projects within the Center that will be specifically addressed for noise treatment. First is the Ankle Orthosis in Test Bed 6, which aims to use a small, internal combustion engine as a power source.

Project 3B.1 will evaluate the potential of engineered lattice materials to provide a lightweight, multifunctional structure to attenuate noise and control structural vibration in the orthosis. The second project is the High-Speed On/Off Valve under development in the Center; a combination of predictive modeling and experimental analysis should yield understanding of the noise-generating mechanisms of the device, and permit reduction of its noise signature.

The future is bright for fluid power, with noise reduction a necessary solution to adoption of more compact devices and expanded use of the technology. * Reprinted with permission from the CCEFP Winter 2011 newsletter. www.fluidpowerjournal.com | www.ifps.org

What’s the Deal with EV’s and PHEV’s?

By Perry Li, Co-Deputy Director and HHPV Test-Bed Leader

The past few months saw the launch of two electric vehicles on the market with much fanfare—the Nissan Leaf and the GM Chevy Volt. The former is an all-electric vehicle whereas the latter is marketed as an electric vehicle with a gasoline engine for extended range. What got the public excited is the seemingly high fuel economics when these vehicles are operated in pure electric mode. The Leaf is listed as having a 99-MPG-e and the Volt having a 93 MPGe. The “e” after “MPG” stands for “equivalent” and is the EPA’s attempt to equate the electricity usage with fuel usage. Are electric vehicles really that much more efficient than engine-powered vehicles? Are they then the solution to our fuel dependence or do they significantly reduce emission of greenhouse gases?

To answer these questions, we need to understand EPA’s definition of MPG-e, which turns out to be quite misleading. EPA defines MPG-e by equating 1 gallon of gasoline to 33.7 kWhr of electricity—this value is the heating capacity of the gasoline and does not consider the efficiency of the electricity generation process. In the U.S., the majority of our electricity is derived from fossil fuel and the average efficiency of a fossil fuel plant is only about 33% (according to DOE). Thus, in a true well-to-wheel comparison, the Leaf and the Volt would get: 0.33*99=33MPG and 0.33*93=31MPG respectively! These are not stellar fuel economies and are significantly lower than those achievable by a well-designed hybrid vehicle such as the Prius (~50MPG). Thus, unless the electricity used to power the Leaf or the Volt is derived predominantly by nuclear or renewable sources, they would actually use more fuel than a hybrid vehicle. While our nation is moving forward to incorporating more and more renewable sources, this will take time.

The analysis and results above are consistent with a study that the CCEFP hydraulic hybrid passenger vehicle test bed (TB 3 – HHPV) research team undertook last year to compare the efficiencies of

Hybrid Electric Vehicles (HEV’s) and Plug-In Hybrid Electric Vehicles (PHEV’s). Fuel and electricity usage data from a fleet of HEV’s and PHEV’s from Google (www.google.com/recharge) driving standard cycles are used. The PHEV’s are converted from the Toyota Prius and Ford Escape HEV’s so that the same basic vehicles can be compared. For the HEV, only gasoline is used and in PHEV, both gasoline and electricity are used. In the study, we ask the question: If all the electricity used by the PHEV is derived from gasoline, what efficiency does this conversation have to be in order to have the same fuel economy as the equivalent HEV? For the Prius, the required conversion efficiency is 41%; for the Ford Escape, it is 37%. The average power plant efficiency in the U.S. is quite a bit lower than these values so that using the onboard gasoline engine can sometimes be “greener” than running on electricity. Details of the study can be found at www. me.mnu.edu/~pli/google_plugin_study.pdf.

How about hydraulic hybrid vehicles? Because of the limited energy density in hydraulic accumulators, plug-in hydraulic hybrids are not a reasonable option. Compared to hybrid electric vehicles, hydraulic hybrid passenger vehicles offer both fuel economy without sacrificing performance, thanks to the superior power density advantage of hydraulics. Moreover, it does not require exotic materials as in batteries or electric motors, making them environmentally friendlier to manufacture and to recycle. They are also more affordable and therefore more appealing to a larger market segment. CCEFP is excited to be engaged in research that makes hydraulic hybrid passenger vehicles a reality. * Reprinted with permission from the CCEFP Winter 2011 newsletter.

A parallel hydraulic hybrid system can be made by adding a pumpmotor, clutch, accumulator and reservoir to the existing mechanical drivetrain.

CCEFP Responds to DOE Off-Shore Wind Energy Request for Information On July 14, the CCEFP submitted a project proposal titled “Development and Demonstration of a Variable Speed Wind Turbine with a Hydrostatic Drivetrain” to a request for information from the U.S. Department of Energy (DOE) titled “DOE Offshore Wind Program—Input Requested for Demonstration Projects.” The response proposed a 3-part project targeted at developing and demonstrating a hydrostatic drivetrain in a wind turbine. The drivetrain would replace the mechanical gearbox in the wind turbine and potentially eliminate the need for power electronics to condition the power before it is sent to the grid. In www.ifps.org | www.fluidpowerjournal.com

Phase 1, a lab scale drivetrain (under 100 kW) would be built and tested. This work would focus on control algorithm development and technology proof of concept. Phase 2 would focus on scaling the drivetrain to approximately 500 kW with development and testing being done in both the lab and in real-world use. In Phase 3, the system would be scaled to off-shore turbine size (5 kW+) and brought to commercialization.

Of particular interest in the proposed project is the exploration of the trade-off between the mechanical efficiency of a variable speed drivetrain and the aerodynamic efficiency of the wind turbine. Research has

been done on wind turbines that take advantage of this trade-off. However, the variable speed wind turbines in development or production are generally 1-3 orders of magnitude lower in power output than what is typically used in off-shore wind turbine applications. The CCEFP proposal aims to take advantage of the inherent reliability, scalability, and power density of hydraulics to create a new generation of very high output wind turbines.
