The Importance of Female Mentors in STEM
 s a society, we learn about the world and advance our well being through science and engineering. The United States may be known around the world for its higher education, but we lack a strong focus on educating scientists and engineers. One significant reason we have fallen behind is that we do not encourage our female students to pursue career paths in Science, Technology, Engineering, or Math (STEM). If we want to attract the best and brightest minds into the fields that will move us forward, we can no longer look to only half of the population. 
 While young people today have more opportunities to become exposed to STEM subjects than 20 years ago, more still needs to be done. Out-of-school programs are gaining popularity, and in order for that to continue, those of us in STEM fields have to support both local and national efforts to foster girls by functioning as mentors.


By Karen Purcell, P.E., owner and founder of PK Electrical

Finding a mentor early on can do wonders for the amount of satisfaction we find in our jobs, thus leading to a higher retention rate. A mentor is not only someone who is willing to take the time to teach us techniques and processes, but also someone who takes an interest in our long-term advancement. Because this person can see one’s potential, he or she is willing to go beyond job duties and put in the extra work to ensure that we gain the understanding needed to progress. However, even with mentorship, the fact still remains that women in STEM careers have higher attrition rates than do their male coworkers and women in careers outside of the STEM disciplines. In 2005, the Society of Women Engineers conducted a retention study of over 6,000 engineering

graduates. The survey indicated that one in four women were either unemployed or employed in other fields compared to one in ten men. Researchers are exploring other factors that possibly overwhelm women in STEM fields, including extreme work schedules, more frequent disciplinary actions, and unclear rules about advancement. Women are gaining numbers in traditionally male-dominated fields, but they are still significantly outnumbered in STEM occupations. Getting talented women into male-dominated careers is one struggle, while keeping them is another. The issue is especially apparent in STEM careers, which is extremely important to the global economy. Attracting and retaining more women in STEM careers will help tremendously to improve diversity, maximize creativity, and boost competitiveness.
 Having people with different mind-sets, capabilities, and imaginations on production teams improves the creative process and helps to minimize avoidable mistakes. Products rooted in science and technology are likely to better meet the needs of both men and women if the products are designed by a team comprised of both genders. It is a matter of designing products that are compatible with a broad audience; it is a matter of safety; and it starts with attracting more women into STEM careers.
 As women become more prevalent in STEM careers, more and more young girls will begin to recognize the additional career opportunities open to them. With more women in the field, it will become more evident to young girls what they, as engineers, can offer the world. Without being able to see this link, they will continue to have problems envisioning certain positions as viable possibilities, even if they have some intrinsic interest in the subject matter. If girls cannot visualize themselves in STEM careers because they have never seen women in those positions, they will be much less likely to ever use their innate aptitudes and abilities in a math- or science-oriented specialty. That will truly be a loss of gigantic proportion, for our women, our profession, and our country.

Global Manufacturing Update By Chad Moutray, Chief Economist, National Association of Manufacturers

January 4, 2013 – While much of the focus of late has been on the fiscal cliff, manufacturers have also been worried about slowing global sales. Business leaders have said that increasing their exports has been a struggle. Yet, despite these headwinds, year-todate growth in U.S.-manufactured goods has risen almost 5%. The good news is that this figure represents positive growth, but it also shows significant easing from the same time period last year. Much of the deceleration in exports corresponded with challenging economic environments in a number of countries, going beyond Europe’s struggles to include Brazil, China, Japan, and elsewhere. The latest data indicates that the global economy appears to be strengthening, which should bode well for improving international trade this year. Europe and Japan are exceptions as both continue to experience significant weaknesses in their respective markets. The purchasing managers’ indices (PMIs) for both remain negative, with new orders, production, and employment contracting. Political and economic uncertainties permeate these data, with manufacturers uncertain about what the future holds. Elsewhere, the trends are more positive. Seven of the top 10 markets for U.S.-manufactured goods have economies that are growing—a definite improvement from three months ago when just four of them did. As a result, we are seeing pickups in manufacturing activity and business confidence. This does not mean that these economies are growing strongly, but it does suggest that global trends have stabilized and are moving in the right direction. Ironically, the political battles over U.S. fiscal policy had implications beyond our borders, with concerns about a possible economic downturn a top concern among our trading partners. This was especially the case for Canada, our largest trading partner, but other nations fretted about our fiscal situation, as well. With a deal to

issues front and center. Nonetheless, the United States is now poised for modest growth in 2013, with rising exports a major contributor both to our macroeconomic picture and to manufacturers’ business plans.

Vacuum Cup Materials Vacuum cups are available in a wide variety of compounds or materials, which are chosen based on the application for which they are intended to be used. There are many different compounds, but most of the cups found in use today are made from four fundamental materials. This article will discuss these four materials and their appropriate application to better understand where and when they should be used in comparison with each other. FIG. 1

here are numerous reasons for choosing a particular compound. The first choice is normally dependent upon the hardness of the material. This will determine the ability of a vacuum cup to seal against the surface of the product being handled. The most common hardness measurement scale used is Shore Hardness, more commonly referred to as Durometer. In fact, a durometer is an instrument used to measure hardness, and therefore, the Durometer scale is the actual unit used to refer to the hardness of the material. The durometer was invented by Albert Shore (b.1876) in the early 20th century in New York City and is so named because it is derived from the Latin word duro, which means “hard or tough.” Fig. 1 shows a typical dial durometer. As the pin is pressed into the rubber, it moves a dial pointer. The harder the material, the more the pin is moved inwards, and consequently, the pointer achieves a higher dial graduation. There are different durometer scales based on the materials being measured, such as plastics or rubbers or metals. The scale used to identify the hardness of vacuum cup mate-



rials is Durometer Scale A, which ranges from 100 (hard) to 5 (soft). Vacuum cups are typically available in compounds with a hardness of 35 to 70 durometer A. Fig. 2 shows a comparison table for hardness options of the most popular cup materials.

“The best way to understand what the cup material should be is understanding the application.” Another, sometimes very important, characteristic of a vacuum cup material is temperature resistance. Most pick-and-place applications occur at room temperature, but in the plastic injection mold industry, for example, temperature is often considered in vacuum cup choice due to the high heat of parts being removed from mold tools. At the other end of the scale is the handling of cold products, such as refrigerated or frozen food packaging. Typical vacuum cup materi-

als have a temperature range from -40ºF to +400ºF (-40ºC to 204ºC). The temperature limitations of standard vacuum cup materials may warrant the need for specialized vacuum cup materials, which are less readily available and may be cost prohibitive. Understanding the actual temperature of the product being handled could save a lot of trouble in vacuum cup material selection. There is nothing worse than everybody in the procurement channel adding his or her own casual safety factor. What started off as a 70ºF requirement could easily end up at 200ºF once it gets to the cup supplier, which is an unnecessary expense. Furthermore, the duration for which the cup is in contact with the load should be considered. If a cup is rated at 200ºF but the part being handled is 220ºF, a two-second or so vacuum hold would unlikely be catastrophic to the vacuum cup. Also, the area underneath the vacuum cup immediately cools under a vacuum due to the reduction of air molecules (a vacuum definition). If the plastic injection mold is 200ºF, this does not necessarily translate to the part being removed being the same. In fact, if it were a thin plastic part, it’s likely that with-

in a matter of moments, it would be cooler. These factors should all be considered. Fig. 3 shows typical temperature ranges of popular vacuum cup materials. NBR, also known as Nitrile rubber or Buna-N, is the most common. NBR is used in general industrial applications and is most certainly found in steel handling, plastics handling, and any other application where the cup should be resistant to oils and related chemicals. In most applications, this is the “go-to” material choice based on its low cost, normal availability from suppliers, and its good wear resistance. The hardness of this compound typically is about 60 durometer, although, depending on the manufacturer, this can be as low as 40 or as high as 70. However, NBR cups are normally 60 durometer. NBR is often overlooked for injection molding as the user specifies very high temperatures and therefore opts for silicone. NBR is more than suitable for most plastic injection part handling as its temperature rating is often near 200ºF. As explained before, the ACTUAL temperature of the part being handled should be understood instead of the mold tool itself. NBR is also suitable for wood and cardboard handling as it has very good wear resistance. This is certainly better when compared with silicone, which is often the only alternative in most manufacturers’ offerings. Silicone is also a very popular cup compound but typically costs some 30-50% more than NBR. Silicone does offer the advantage of having extreme temperature resistance— both cold and hot, ideal for handling frozen packaged food and hot plastic-injected molded parts with a temperature range in excess of 450ºF (230ºC). Silicone is typically softer than NBR, allowing it to seal against contoured or rough surfaces, such as cardboard sheet, corrugated plastic, and plastic food packaging. Silicone is also offered with FDA (title 21) compliance to allow it to come into direct contact with food and drug products. The FDA specification basically ensures that dyes and colorants do not bleed out when handling food and drug products, which would contaminate the process. Metal-impregnated silicone is also very popular in the food industry. In high-speed production lines, metal detectors can

sense that a vacuum cup has fallen into the food packaging that typically contains baked goods like bread loaves, rolls, and buns. The wear resistance of silicone compared to NBR is poor. Typically on an abrasive surface such as cardboard, an NBR cup would last at least twice as long. That said, silicone has a better seal on the cardboard, and consequentially, a higher vacuum level can be achieved, which offers higher load capacity for the tool. One feature trades off against the other. There is one very important note about silicone that must be understood by the vacuum cup user. Silicone should never be used on surfaces to be painted, such as automotive body panels, as the paint will not bond properly on the area touched by the silicone compound cup. The end result known in the paint industry is “fish eyes.” Most automotive plants involved in steel stamping and paint-

ing of car bodies do not allow any silicone products in the factory at all for this reason. Polyurethane vacuum cups are used in potentially high-wear applications. Polyurethane has very high wear resistance compared with both silicone and NBR, but typically is more expensive. The temperature-resistance range is a lot less than both NBR and silicone, as shown in Fig. 3. Some manufacturers offer dual durometer vacuum cups, as shown in Fig. 4. The dual durometer cups offer a softer than normal sealing lip of about 30 durometer but a harder body, maybe 60 durometer, to offer stability in high-speed transfer and even vertical shear plane lifting. The disadvantage of this type of dual compound beyond all else is that it is very expensive to produce, being a manual process, compared with the NBR and silicone compounds, which are produced in larger quantities automatically or in multiple cavity molds. Vinyl cups or PVC (polyvinyl chloride) cups are a relatively low-cost alternative to the aforementioned materials of NBR, silicone, and polyurethane; however, the mechanical properties of PVC, which is a plastic material, is inferior to that of the rubber compounds. Although rubber products wear more quickly than PVC due to abrasion, PVC will more likely “work harden” and fracture. This is normally found at the stress points of the cup where the most movement occurs, such as a bellows corner. The fact that PVC is very hard wearing does not offset its poor mechanical performance. Typical PVC cups have a limited temperature range and durometer offering. PVC cups tend to be a lower initial cost, but consideration should be made to the ownership cost with regards to their typical shorter life compared with other readily available compounds. The color of various compounds depends on the manufacturer. NBR cups are normally black, silicone typically red or white but available in all types of colors. Polyurethane is available in a whole host of colors. The point is, you cannot tell the compound of a vacuum cup just by looking at it. The best way to understand what the cup material should be is understanding the application. Does it NEED to be silicone? Could NBR, which is less expensive, be more suitable? Understanding the application is absolutely key in selecting the correct compound. And, like all applications in manufacturing, just because that’s what is being used now does NOT mean that’s what should be used going forward. 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.

Steering Valves ‰ The company’s hydraulic steering control units are now being supplied for high-performance speedboats. The compact structure of the 101 series steering control unit allows for greater steering force with less force. The 101S series has relief valve, shock valve, suction valve, and check valve functions inside one housing. Specifications for the 101 series include displacements of 3.05 in/r to 24.41 in/r, rated flow of 1.32 gal/min to 10.5 gal/min, max input pressure of 2,320 psi, and max back pressure of 362 psi.

Phenolic wear bands were a mainstay in hydraulic cylinders, however due to the formaldehyde content, they have largely been replaced by glass-filled nylon. If compressive strength requirements are below 25,000 psi, glass-filled nylon is the best bet. Suppliers stock the common sizes, and you can avoid a costly penalty. Uncommon phenolic sizes can be ten times the cost of glass-filled nylon, and with nylon, you don’t have to worry about a visit from OSHA.

So you need to replace an unlabeled external gear pump originally sold by Cro-Magnon Hydraulics during the First Crusades, and sadly you have no idea of the displacement? Find the root and tip diameters of one of the gears, assuming the gears are identical, and the length of one gear, one side to the other. Figure the volume of two cylinders based on those two diameters and that gear height, and subtract the smaller volume from the larger. This will be very close to the displacement of the pump (or motor). Just because you have two gears, don’t be tempted to multiply the answer by two. The total displacement is the sum volume of all teeth in the pump (or all voids between the teeth), and that single hollow cylinder you by Stephen L.

Tobul’s SEAsure™ depth compensator is specifically designed for offshore drilling/production applications that demand high strength performance and resistance to seawater. The SEAsure™ depth compensator utilizes undersea pressure to compensate for installation depth by allowing seawater into the fluid port. The incoming seawater applies pressure to the internal bladder (filled with liquid), which is discharged through the transfer coupling (connection block) to the POD.

Tobul Accumulators are an integral part of the control and operation of subsea drilling/production systems; and are used to ensure sufficient hydraulic power is available to activate hydraulic actuators and motors, electro-hydraulic control POD’s, blowout preventers (BOP’s), and gate valves for flow control of oil & gas to the surface or other subsea locations.

“Good Housekeeping� Keeps Solenoid Valves Happy By Johanna Baril, Parker Fluid Control Division


he health of any motion control system is only as good as the health of its components. Because of their small size, solenoid valves can sometimes get overlooked in a system maintenance regimen. As valves control the flow of fluid, air, or gases for a much larger system, such maintenance oversight can lead to problems with the entire application. Proper maintenance can extend the life of the valve and guarantee its consistent operation for many years. While maintenance schedules largely depend on each specific application, this article answers some frequently asked questions about solenoid valve maintenance and repair.

18 |

Frequently Asked Questions

1 Does the valve maintenance really make that much of a difference to the system?


Choose Wisely to Avoid Future Problems The best predictor of the valve’s performance over time is how it fits the demands of an application. What sometimes looks like a maintenance problem is actually the result of an improper product selection. It is important to evaluate the following three factors:

The valve’s environment: Conditions outside the valve can occasionally be harsher than the media flowing through it. In such cases, the coil must be protected from moisture and thermal cycling with various coil construction and enclosure designs. For example, NEMA 4 watertight coil enclosures are used in outdoor or wash-down situations. Built-in protection at the selection and specification stage will provide the best defense against possible operational issues in the future. Media flowing through the valve: Solenoid valve manufacturers create products that meet certain pressure, temperature, and flow criteria. Depending on the valve’s purpose, it can be constructed of brass, stainless steel, aluminum, copper, and various rubbers and plastics. It is important to ensure that the media flowing through the valve will not negatively affect these materials. Pitting, wire draw, rust, and deterioration are all preventable with proper material selection.

A maintenance regimen for solenoid valves can help avoid expensive repairs and downtime, lengthen the valve’s life, and keep the application running smoothly. To maintain a solenoid valve, personnel need to identify the affected areas and then clean, lubricate, fix, or replace them.

The application itself: Solenoid valves are used in a wide variety of applications, and selecting the proper valve to suit an application is critical for its performance. Tank drain valves and vacuum applications are best served by valves that do not have a pressure differential requirement. Directacting valves, whose minimum operating pressure differential is zero, perform well and will provide a full flow within 25 milliseconds. In many cases, the valve selection should not be limited to port size, voltage, and pressure-rating requirements. Slow closing or anti-water hammer valves can improve the life of an entire system. It is well advised to analyze the needs and specifics of the entire application and the valve itself to determine whether to adopt a maintenance or replacement regimen for the solenoid valve. Overall, maintenance will help extend the life of a solenoid valve, avoid expensive repairs or postpone replacements, minimize downtime, and keep the application running smoothly.

Even the most reliable valves can wear down or malfunction over time. A maintenance regimen can help avoid expensive repairs and downtime, lengthen the valve’s life, and keep the application running smoothly. Below are three typical scenarios where routine maintenance significantly reduces overall expenses: A standard valve can wear out even when controlling such common media as air and water. Dry air and rapid cycling applications are among some of the most damaging to the valve’s operation. Because media moves through the valve, lubrication does not tend to stay inside the valve and may need to be re-introduced at various times. Without lubrication, the regular hammering of the internal parts can wear down the components, and the valve may need replacement at 100,000 cycles or less. Additional lubrication can extend the product’s life by millions of cycles. Valves that control water – a natural source of lubrication – can experience mineral buildup, which worsens over time. That can be easily prevented with regular cleaning. When a solenoid valve is designed with small orifices or clearances between moving parts, unfiltered or viscous media may have difficulty passing through the valve, and this can increase the possibility of premature failure. The valve must be specified correctly for such applications, i.e., the media should not have suspended solids, and a filtration device should be used to help prevent contamination.

Frequently Asked Questions

2 When is it the best time to check the valve? It is most convenient to examine the valve when a piece of equipment is already being taken apart for servicing. The valve should also be checked at regular intervals, and frequency depends on the application and history of the valve performance. Proactive measures will extend product life and promote the best possible performance for the valve and the system.

When is it time to repair and to replace? When faced with a repair-or-replace decision, it is important to consider the valve and the entire application. Simply designed and constructed valves are relatively inexpensive to replace when compared to the cost of repair. The labor required to disassemble the valve, replace the parts, reassemble, install, and check for proper performance is generally more expensive than installing a new valve. Valves with complex designs will be costly both to repair and replace. This is a situation where proper maintenance is especially important from the cost perspective. With complex designs, field repair may not duplicate the valve’s original performance, and replacement is often the best way to go.

6 20

The solenoid valve’s design and purpose and the application’s requirements determine how frequently it should be checked. Below is a list of questions that will help determine the answer: 1. If the valve fails, is there a risk of safety hazards? 2. If the valve fails at the worst possible time, what are the consequences? 3. How much will it cost to eliminate the consequences of a valve failure? The cost should include lost productivity and repair or replacement. 4. How much does it cost to service a valve? Include time and resources.




How often should the valve be checked?

Despite their small size, solenoid valves perform an important task. They control the flow of fluid, air, gases, or particles for a much larger system, and their functioning affects the operation of an entire application. Selecting a valve that is a perfect fit for the demands of an application will help the valve perform at its best over time. Sometimes, what looks like a maintenance problem is actually the result of an improper product selection.

What are the steps to follow in any valve maintenance regimen?

5 What does a proper maintenance regimen involve? To maintain a solenoid valve, it is important to identify the affected areas and then clean, lubricate, fix, or replace them. The components of the valve must be clean and free of foreign matter as any buildup can affect the valve’s ability to energize and de-energize. While the valve’s rubber parts and springs are replaced most often, any internal part showing wear or damage should be replaced. The valve’s connection should also be checked. When the connection has sweat fittings, one might consider rebuilding the components instead of removing an entire valve from the system, which can be costly and time consuming. The same is true if the connection’s placement makes the removal of the valve difficult or dangerous. Finally, the valve’s seat needs to be checked to make sure it is not nicked or worn; otherwise, the seat can leak, even if the seals are new. Valve manufacturers are a good resource for valve maintenance as they offer replacement part kits and maintenance instructions with exploded views. These can include replacement O-rings, springs, plungers, diaphragms, pistons, and other components.

1. Before working on the valve, disconnect the power source and depressurize the system. If the unit controls corrosive or hazardous substances, follow the proper safety procedure while handling it. 2. In wet or humid environments, moisture might penetrate into the coil and create cracks, causing a valve failure. When servicing the valve, inspect the coil for cracks and check its connections for damage or corrosion. Power up an AC coil to ensure it is properly installed on the valve’s sleeve or stem; if it is installed improperly, the flood of current might cause the coil to overheat and fail. 3. Remove the coil to inspect the remaining unit called the “pressure vessel.” Its sleeve can be removed by a sleeve removal tool, if required. While removing it, avoid fastening onto the sleeve tube because this might dent or bend the tube. Once the sleeve is removed, the internal components of the valve operator can be seen, including the plunger with a seal, the plunger return spring, an O-ring, the sleeve, and operator body. Examine all components for damage or wear and replace as necessary: • The seal should not be swollen, cracked, or deteriorated. • The spring should be checked for worn or broken coils. • The body orifice might be nicked or the crest might be worn out. • When the plunger lifts, it typically makes contact with the sides and top of the sleeve. As a result, the outer diameter and top of the plunger may show wear. If a solenoid valve is more complex in design and contains diaphragms, pistons, spools, and levers, the manufacturer's maintenance instructions should be closely followed. 4. Replace worn-out or damaged parts and clean the valve of any build-up and dirt. Refer to the manufacturer’s instructions to re-assemble the pressure vessel and re-attach the coil. Finally, re-install the newly assembled valve back into the system.

& Q A

Mobile Market With John Treharn, Massimo Dovesi, Steve Zumbusch, and Trent Tegg


John Treharn, Vice President Business Development – Hydraulics Group, Parker Hannifin Corp. John works with the company’s divisions to advance long-term growth strategies. He also helps define acquisition candidates and due diligence oversight when an acquisition is pursued. With 40 years of experience, he oversees development of business contracts with customers and development partners.

Massimo Dovesi, Global Sales and Marketing Director, Turolla OpenCircuitGear (OCG) Massimo has more than 15 years of experience in hydraulic engineering and sales/marketing. He has covered different roles during his career, designing and selling hydraulic components and systems. He has sales and marketing experience in the North American market and also in the APAC area, with a specific focus on India. He is currently based in Italy.

Steve Zumbusch, Director of Application and Commercial Engineering (ACE), Eaton’s Hydraulic Group After graduating from the University of Minnesota, Steve joined Eaton as a product development engineer, and over the last 30 years worked on different product lines and applications. His experience includes the role of engineering manager for the company’s power division, and he has received nine patents for a number of innovations.

Trent Tegg, Vice President of Sales and Engineering, DTS Fluid Power A certified fluid power specialist, Trent joined DTS Fluid Power in 2007 as vice president of sales and engineering. He previously served as Michigan branch manager for Sentinel Fluid Controls.


‰ In respect to the economy, in what areas do you see the mobile market picking up momentum or slowing down?

Treharn: Reflecting back, 2008 was a peak year for the mobile motion control market in North America. We saw a severe recession in 2009 and 2010, with a significant (but not total) recovery in 2011 and 2012. We anticipate no significant market momentum changes in either direction during 2013. Growth will result from adding incremental customer value and winning market share. Dovesi: It is difficult to predict 2013 since it’s a year dominated by an economy that is trying to exit an important slowdown, and a number of OEMs are trying to reassure the market that we’ll see a growth. There is a lot of goodwill from the players, a lot of manufacturers ready to invest again, but we don’t have yet a sign that is safe to do so. As a result, I believe we will have a year that will be uncertain and mostly based upon the ups and downs in production. As a whole year, it could be flat, but there will be times where positive signs will come to the manufacturers that will transfer to component manufacturers.

Zumbusch: We are seeing a lot of folks maintain a cautious stance regarding the future. A number

of manufacturers saw declines in orders, especially in construction equipment and followed by agriculture industries. However, we are seeing a number of customers continuing new equipment projects across the globe, particularly in Brazil and Asia Pacific, that are getting exciting.

Tegg: We definitely see an upturn in momentum in the woodlands industry. With new home and business start-ups, more land is being cleared. And with all of the strange weather and major storms of late, the chipper market has been brisk. On the other side, we have seen a reduction in some of our farm equipment OEMs. We believe this is mainly due to farmers switching from the crops that they typically grow to corn and beans as their prices continue to skyrocket. ‰ How have the Tier IV emissions requirements made it easier and/or more difficult to conduct business?

Treharn: Tier IV emissions requirements have created a lot of opportunities—and challenges— in designing equipment and cooling systems with a bigger emphasis on efficiency. Dovesi: Tier IV engines have been both a plus and a minus for us. Looking at them strictly from our

perspective (therefore ignoring the obvious benefits related to emissions), they have introduced a need for more and better cooling systems. The minus of the Tier IV introduction is the critical mass of work that our customers need to do to introduce them, stealing time for machine redesign or improvement. It also has had an impact on the cost of the machine and ultimately on the ability of the manufacturer to capture “perceived” value from the customers; for example, the same machine from the past is now sold with just a different Tier IV engine (and a higher price), transferring to the market those extra costs without new features that could improve performance, comfort level, and ease of use.

Zumbusch: Hydraulic solution providers like Eaton have been anticipating the impact of Tier IV on costs and power availability for a while now. We recognize the balancing act OEMs have been facing in getting their engines selected and qualified versus time available to look at improving power management. With the dust settling on interim Tier IV and Tier IV Final, we believe that the need to manage available power will be more and more important. I think OEMs have started seeing the need to optimize their machines and

march/april 2013


Q &A

deliver more to the end user for all the extra costs that came into play with Tier IV. This realization has allowed the message of higher-efficiency system solutions to start making its way into the discussions and next-generation system designs.

Tegg: We have found that we have less engine “real estate” to work with as far as mounting our products to the engine, which makes power to size/weight ratios more important than ever. The requirements have made it crucial for the OEMs to have hydraulic systems that use state-of-theart variable platforms and high-tech controls that self-adjust to the new engine performance curves. One of the biggest benefits that we see coming from the Tier 4/3 engine platform is how easy it is to communicate with the engine through J1939. With our new CAN (controller area network) systems, we can tell exactly what is happening with the engine at all times and, within milliseconds, adjust the system to what best suits the requirement while optimizing the machine output and performance. ‰ How has the increased focus on energy efficiency affected the mobile market’s role in fulfilling customer requirements and designing equipment?

Treharn: Our customers’ core emphasis is in designing and manufacturing equipment with higher levels of efficiency. As a result, I believe we will see more “high-end” engineered solutions to meet the requirements of the next generation of equipment. Dovesi: As a component manufacturer, the request for more efficient machines is an opportunity to improve the technology. (I’m referring to a system that saves fuel consumption and improves controllability, like load-sensing technologies). As systems become more sophisticated, from the technical point of view, there needs to be more interaction between engineering departments and customers, and a need to resolve issues related to electronics communication or the system’s hydraulic responsiveness to the machine inputs. The past approach was more “single-component” related, but now I think that a higher technology level requires component manufacturers to better understand the entire system that controls the machine. Only by doing this can the manufacturers propose solutions for improvement.

Zumbusch: The increased focus on energy efficiency is causing mobile OEMs to take a new view on their equipment. As a result, they are recognizing that to manage the power most effectively, they need to be looking at the complete machine, not just individual components. Operating cost increases sparked by fuel prices and Tier IV engine packages have put everything


hydraulic on the table for discussion—from parasitic loss analysis to more intelligent system controls. In the end, these machines still have to prove themselves—adding to the bottom line and delivering for end users.

Tegg: The energy focus has forced our OEMs in the agriculture, woodland, and material-handling industries to adapt to higher-efficiency products to optimize fuel-in vs. worked-performed ratios. With some of our customers’ larger platform machines, they can burn as much as 70 gallons of fuel per hour. Figuring fuel cost at $4.00 per gallon, it totals $2,240 in an eight-hour day, or $56,000 per month, or $672,000 per year. It is easy to see how quickly a 20% savings could add up. If we are able to control the engine to maximum efficiency at all times with our new controls system and design in load sensing and other high-efficiency products, the return on investment is realized very quickly, which will lead to more sales for all involved. ‰ What areas of opportunity in the mobile market segment do you see as growth areas in 2013?

Treharn: I see a lot of growth in electronic controls—pumps, valves, actuators, etc.—and a continuation of using electronics to add intelligence to hydraulics.

Dovesi: In a market that is uncertain for volume and expansion, I think that as a manufacturer, we are a little bit in between the OEMs that drive the change and the market itself. More than market opportunities, I see specific opportunities at some OEMs to invest in new machines. Each market segment has leading customers and followers, and today we are seeing the gap between these two categories growing due to the investment level they can afford. If we want to look at the different segments, the potential growth is really related to what a certain component manufacturer has already done in that segment; looking at our company, specifically, we do have multiple opportunities in the lifting, construction equipment, and agricultural market due to the release of new products and the integration of improvements and accessories. Zumbusch: Electro-hydraulics (or more accurately, mechatronics) in the mobile market has been growing for some time—and presents a number of advantages for OEMs. As the need to manage every bit of power produced by the machine continues to dominate design, we’re looking for more integration of power management. Controls that intelligently manage the combined engine power production and the hydraulic power conversion will be important for customers this year and in the future.

Tegg: We see a great opportunity in the CAN controls arena and the electro-hydraulic product that links it. We definitely see growth in any products that interface engine controls with hydraulic controls. |

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

Treharn: In general, I see continued innovation by adding electronic intelligence to hydraulic components, such as displacement control for piston pumps. Electronics coupled with hydraulic components and systems will be used to improve equipment safety, operator productivity, and optimized energy utilization for mobile equipment. Advanced series, hybrid transmissions are also starting to gain momentum, as they are now delivering significant fuel savings and emissions reductions on heavy vehicles with high stop/start duty cycles.

Dovesi: As a gear pumps/motor manufacturer, I don’t see an innovation we can define as an upcoming game changer, as this mature product has been through multiple improvements and redesigns over the years. There are pockets of technology improvement here and there, maybe more related to manufacturing processes rather than technology. Silent pumps will need to be more cost effective, and their usage could improve in different areas. There’s an opportunity to bring more value with a package that includes accessories that before were installed along the hydraulic line. I believe we should question ourselves more about the future of our segment, understanding how a mature product can change and still bring value. The competition from low-cost countries will drive many decisions and force us to diversify this added value to remain attractive and competitive. I do see many game-changer technologies out there for other components that could dramatically improve machine performance and ease of use, which is going to be a major factor in the coming years.

Zumbusch: Machine costs are king. Today and likely moving forward, we expect this issue to continue to be critical for end users. They need the machines to be reliable and reduce unexpected downtime to keep profits flowing. Products that can accurately predict replacement and maintenance needs are yielding value for customers as they seek to reduce operating costs. Sensing technologies like these will continue to be game changers going forward.

Tegg: Eaton’s new E-controls—This new open architecture is by far a game changer for our industry. They have developed a control platform that is very intuitive and does not lock the end OEM customer out. With process rates of three milliseconds, we are able to keep up with engine communication (J1939) and DTS’s design team builds the ability through onboard HMI troubleshooting screens to tell the user/ OEM exactly what has failed from the engine to the pump to the directional coils or even the wiring. This lets the end customer know exactly what is happening with his machine and most of all, keeps downtime to a minimum.

The Navy had excellent hydraulic technical schools and I was fortunate to have good leaders around me, so the experience was a great one. That experience taught me how to use my brain and think outside the box to make repairs to equipment while out at sea to ensure the ship made its commitments. That training and experience qualified me for a position as a hydraulic mechanic with Coastal Hydraulics after I left the Navy. After a few years learning from the experts at Coastal, I assumed responsibility for all the hydraulic mechanics and machinists when I was promoted to director of operations. That opportunity led to my most recent promotion in 2007 to president and CEO. What is the most memorable moment in your fluid power career, and what did it teach you? ‰ My most memorable moment was the first time a customer personally thanked me for helping to keep his manufacturing plant up and running. I learned that I could utilize the fluid power industry and make a difference in others’ lives no matter how menial the task at hand seemed. Every job deserves quality.

he National Fluid Power Association (NFPA) has completed another successful round of Fluid Power Challenge events. The Fluid Power Challenge is a skills competition that invites eighth grade students to solve an engineering problem using fluid power. They work in teams of four—two girls and two boys—and learn science, technology, engineering, and math (STEM) skills in the process. At four events this fall and winter, 112 teams, or 448 students altogether, were exposed to fluid power. This means that since the program was started in the U.S. in 2008, more than 2,000 middle school students have learned about hydraulics and pneumatics. Go to for highlights and videos from all the recent challenges. To recap, four challenge events were held this fall and winter:

Lead Unconventionally and Beat the Competition By Eric J. Romero, Ph.D.


eaders inspire people to do amazing things—the type of things that their followers would not do on their own. With leadership, a vision and competitive advantage becomes reality. The more change an organization is facing, the greater the need for leaders. The more flexible a firm must be to survive in its environment, the greater the need for leaders. Given that today’s environment is characterized by frequent change, leadership is more important than ever before. Unconventional leaders go a step further. They lead their companies to repeatedly create things that people love, but no one expected, especially their competition. Unconventional leaders are fanatical about the products and services they provide rather than profit, yet they tend to lead the most profitable firms in their


industries. They create organizations built on innovation, flexibility, and risk-taking, which redefines their industries and sometimes the way people live. Through their companies, they often lead other firms in terms of technology, customer service, etc. Unconventional leaders beat the competition on a regular basis. Steve Jobs and Mark Zuckerberg are prime examples of unconventional leaders. They do not look like typical business leaders, and their leadership style is anything but conventional. In fact, their backgrounds are both contrary to what most people would expect of such successful corporate leaders. They both dropped out of college and have no formal management training. Despite this, or maybe because of this, they have unconventional leadership styles that have led to the creation of unconventional firms. In fact, the people with the most education and experience are often the most conventional thinkers.

Unconventional Thinkers Unconventional leaders are unconventional thinkers, but what does that mean exactly? |

Unconventional thinkers stand out compared with most people. Their ideas are an amalgamation of ideas from a wide range of areas. They often use bits and pieces of very simple concepts in unique combinations to create new solutions to new or old problems. Their unique thinking is often reflected in their eclectic mix of interests and people with whom they form relationships. They like information and ideas, and often focus on things that most people overlook. Unconventional people like to think about things and understand them fully. To illustrate further, below is a comparison of conventional and unconventional thinkers.

Conventional Thinkers • Like safety, avoid risk • Say things like, “this is just the way we do things” and “everyone does it this way” • Accept things as they are presently • Will avoid expressing their ideas unless agreement is likely • Follow trends • Are less willing to think, rather continue doing things the same way • Feel agreement is very important, as is consistency • Have a negative perception of differences: these are weird, strange, odd, etc.

• Do not question why things are the way they are, do not think of a better way • Value established knowledge

Unconventional Thinkers • In the quest for improvements or even perfection • Think and act differently than most people • Re-evaluate everything, including their beliefs and assumptions, and change them if necessary • Integrate disparate ideas and knowledge into new ideas and solutions • Are not restricted by other people, do not care what they think or do • Like change, see it as an opportunity for improvement • Willing to try new things and learn from them, whether or not they work out • Believe that constructive conflict is good, leads to more ideas and a better understanding of issues • Openly express what is on their minds • Value thinking and creating new knowledge Although it might not be an easy change, conventional thinkers can become more unconventional in their thinking. Everyone is born an unconventional thinker. Just observe very young children, and you can see the amazing creativity they have. Unfortunately, as kids get older, they are taught to think like everyone else in their family, at school, etc. They learn to become conventional thinkers. However, if this can be learned, it can be unlearned. You might not become as unconventional and innovative as Steve Jobs, but you can become far more unconventional in your thinking. Therefore, you can become a more unconventional leader. Below are some ideas that you can use to start on that path.

Become a More Unconventional Thinker • Force yourself to try new things: music, food, activities, travel, etc. • Question everything you do and believe, stop doing things to fit in or just because everyone else does it. • Get used to people not agreeing with you. Always tell people what you think, even if they might not like it. • Debate with people who disagree with you in order to understand their point of views. Accept their ideas even if they are different. • Talk to people who are totally different from you – younger, older, retired, foreigners, different professions, etc. – and learn from them. • Try new ideas even if you are not 100% sure they will work. • When new ideas don’t work out, view this as part of the learning required to try new

things, the cost of creativity, not as a failure or mistake. • Don’t take yourself too seriously. Use humor to make fun of yourself when things don’t work out. Doing the above activities is easier if they are done with other people, so look for groups that can you can join or create to help you become more unconventional. While changing is not easy, becoming an unconventional leader has

the potential to help you create significant competitive advantage based on innovation, flexibility, and risk-taking.

Fan Drives in Mobile Hydraulic Applications


ith increasing demands on mobile equipment manufacturers to produce emissions-compliant and highly efficient machinery, new methods for saving energy have become necessary. Mobile equipment has evolved much over the past several years due to these regulatory demands. One area where a significant amount of machine energy is wasted is in the cooling system.

36 |

The need for a cooling system arises because much of the fuel energy that goes into a machine is lost in the form of heat due to inefficiencies of all types. If this heat is not managed properly, a variety of system failures can occur and therefore render a machine useless. Machine cooling is a necessity and, therefore, a significant portion of energy must be dedicated to operating the cooling system.

The ultimate goal of the cooling system in mobile machinery is to control the temperature of the various components of the machine. This temperature control can apply to a variety of onboard systems not limited to the following: • Engine charge air systems • Hydraulic systems • Engine cooling systems


Above: Proportional hydraulic fan drive system using a PLUS+1™ microcontroller Opposite Page: Proportional reversing motor (Images courtesy of Turolla OCG)

• Operator climate control and air conditioning • Transmission cooling • Power electronics cooling • Emissions systems (exhaust gas recirculation cooling) Several different methods can be used to manage excess heat in mobile machines. For simplicity, this work concentrates on the use of a driven fan to move heat out of the machine. The method for driving the fan has traditionally been mechanical, consisting of various combinations of shafts pulleys and gears attached between the engine and the fan. The drive ratio between engine and fan has traditionally been selected to provide adequate cooling across the entire range of engine speeds at the maximum-designed ambient air temperature and the maximum system heat rejection. This method is required to prevent overheating of the various systems, which can lead to the subsequent failure of those systems and expensive repairs. The power consumption of a fan as a function of its speed can generally be described as proportional to the third power of the fan speed. This relationship is the ultimate reason for designing a more efficient fan drive system. By reducing the speed of a fan by 10%, the power consumption of that fan can be reduced by roughly 33%. A much more efficient way to operate a cooling fan is to adjust the fan speed independently of the speed of the engine and proportional to the amount of cooling required for the system.

For the right fan and cooler combination, this method would provide adequate system cooling at all conditions while at the same time minimizing the fan speed across the drive cycle to avoid excessive energy consumption. Several different methods for proportional cooling exist on the market today. These methods include, but are not limited to, electroviscous clutches, mechanical continuously variable transmissions, electric drives, adjustable pitch fans, and hydraulic drives. Proportional hydraulic fan drives can be realized through various methods ranging from the simplest open-circuit system through the most complex closed-circuit system. Due to relative simplicity and low cost, the majority of low-powered hydraulic fan drive systems consist of a fixed pump and fixed motor with a proportional bypass valve to provide speed control in the system. The bypass valve can be thermo-valve actuated or electronically actuated to adjust fan speed to provide adequate cooling. Reversing can be accomplished through the use of a bidirectional motor and a directional control valve. Medium-power systems may consist of a pressure-compensated open-circuit piston pump and a fixed displacement motor. In this system, the fan speed is controlled by controlling the pressure compensation setting of the pump. The setting is normally electronically adjusted. Reversing for this system can be accomplished using a bidirectional motor and a directional control valve.

High-power systems may consist of closedcircuit systems where a large over-center piston pump drives a fixed displacement motor. In this case, both the speed and direction of the motor can be controlled by controlling the displacement of the pump. For all of the previously mentioned systems, fail-safe controls must be implemented to avoid overheating of machine components. This is accomplished by forcing the system to demand full fan speed in the case of a loss of control signal. In addition to efficient proportional fan control, hydraulic systems offer several other advantages. The flexibility to locate the cooler in a different part of the vehicle and at a different orientation allows for more efficient cooling. This flexibility can also save space near the engine for emission-control hardware. The ability to reverse the fan through the use of valves or over-center pumps also allows these to be applied in dirty environments where reversing the fan can clean out the cooler. This is especially useful in agriculture applications where crop material can quickly plug the cooler and thereby reduce cooler efficiency. When considering proportional fan drives, it is also good to know that noise legislation can have an effect, as well. Proportional systems are only required to be qualified at 70% of full speed when compared with fixed ratio systems. This allows the fan to operate at a much quieter point for noise qualification, while at the same time allowing the machine the ability to achieve its required cooling capacity. Because hydraulic fan drive systems can control the speed of the fan proportional to the cooling requirement of the machine, they have proven to be an effective and efficient way to reduce energy consumption in mobile machinery. The added packaging flexibility, fail-safe modes, and reversing functionality that hydraulics can provide offer additional value to these systems.

Hydraulic Shop Salvages Cylinders with Tube Hone, Saves Customer


ebuilding heavy equipment makes good economic sense, particularly for the hydraulic components on construction and earth-moving machinery. In fact, the trend since 2008 has been strong enough to support the addition of a machine shop as part of the existing hydraulics shop at Caterpillar dealer Whayne Supply. Key among the shop’s equipment is a Sunnen HTA tube hone, which allows Whayne to resurface scratched and rusted cylinder barrels, saving customers 80% or more over the cost of a new barrel. Brought in as part of a beta test of Sunnen’s new all-electric machine design in 2009, the hone has been used to process more than 1,000 barrels. Bringing this previously outsourced machining work in-house has helped the company add revenue and staff while also improving control of delivery schedules and costs for customers. “Simple economics dictate that customers are going to be rebuilding machines until the economy – and the coal industry in our region – both


strengthen significantly,” said Mike Harbin, manager of Whayne’s power rebuild center. “We have customers who are tearing down machines in the field and completely rebuilding them. The machine shop and the honing system have helped us stay on top of this trend. We have added five people in our shop alone to handle the increased volume.” Whayne has rebuild centers in Louisville and Corbin. All exchange/resell goods are processed in these shops. The hydraulics shop in Corbin has eight cylinder technicians, three full-time machinists, three pump experts, plus a foreman and service coordinator. The Corbin operation added a machine shop to its hydraulics shop in 2009 that included two vertical mills, two lathes, a drill press, a rotary surface grinder, welders, and saws. The shop stocks various sizes of chrome-plated bar and DOM tubing, some of it pre-cut for standard Cat sizes. The shop has five cylinWhayne Supply has honed hydraulic cylinders up to 21-feet long, saving customers 80% over the cost of a new barrel.

The HTA hone is designed for optimum performance with Sunnen ANR275 tooling and abrasives, sold with machine coolants and gauging as part of the machine package. (Top left) Whayne honing operator inserts the tool at start of a cycle. The company has honed cylinders with bore ID up to 17 inches. The HTA tube honing system handles parts weighing up to 8,000 lbs (2,629 kg) with ID ranges from 2.4 to 21 inches (63.5 to 533 mm). (Bottom left) Whayne honing operator changes abrasives to perform both roughing and finishing of the bore.

der service bays – one for suspension cylinders, one for lift cylinders on small loaders, and three for high-force cylinders. “We can replace the barrel, rod, rod eyes, head/seal areas, hydraulic lines and connections, or custom fabricate new cylinders to spec,” said Michael Carter, service coordinator. There are four hydraulic cylinders on the average Cat machine, so the shop stays busy, processing about 1,000 cylinders in 2011. “During the summer, we may have a hundred or more cylinders outside our shop waiting to be rebuilt because our indoor storage is full,” Carter added. Honing Cylinders for Customer Savings and Shop Profit The shop’s old hone consisted of a drill motor on a sliding carriage and lacked the power, capacity, and rigidity needed for doing serious work, according to Carter. “It could produce a surface finish but not remove metal.” Whayne agreed to beta-test Sunnen’s new all-electric HTA cylinder hone and later purchased the machine with a 12-foot (4-m) part capacity. The HTA tube honing system handles parts weighing up to 8,000 lbs. (3,629 kg) with ID ranges from 2.5 to 21 inches (63.5 to 533 mm). It is designed for resurfacing and repair work where light-duty stock removal up to 0.030 inches (0.76 mm) is required. Standard models are sized for 6-foot (2-m) and 12-foot (4-m) part lengths, and custom lengths are available. The HTA is equipped with a Siemens drive and PLC-control with touch-screen HMI for setting machine parameters such as stroke reversal point, spindle/stroking speed, and crosshatch angle calculation. The control features a load meter to determine areas of bore tightness and provides the ability to dwell the tool in multiple areas to correct part geometry. A touch-screen-controlled hone provides a safer working environment and reduces operator fatigue. It also provides better quality parts by producing a controlled crosshatch pattern, which allows the honed surface to retain oil or grease, ensuring proper lubrication and ring seal of pistons in cylinders. “We were not sure about downtime for a new machine, but it has proven extremely reliable, and we’ve used it to hone cylinders from 2.5 to 17 inches (63.5 to 432 mm) diameter and six inches (152 mm) length to over 21 feet (6.4 m),” Carter added. “We simply created a table with an adjustable-height V-block to support parts that overhang the machine. We have used up to a 21-foot drive-shaft length on the machine, and we can hone from both ends of the part if need be. Our cycle time for most barrels is about 30 minutes, which includes setup, honing, and washing the part.” For additional Whayne uses both roughing and finishing abrasives, removing information scratches and rust, and imparting a specific crosshatch surface finish on the barrel bore. “We can increase the cylinder bore diameter up to on Sunnen tools 0.254 mm (0.010 inch) in relatively short time, removing rust and all but and abrasives, contact: Sunnen the worst scratches, and remain within Cat machine specifications,” Products Company, Carter said. “Our old hone simply could not do this. The HTA hone is 7910 Manchester easy to setup, also. The control calculates the correct crosshatch angle. Rd., St. Louis, It’s been a very reliable system, too, with no appreciable downtime.
