Social Media: The Great Game Changer

M

You unlock this door with the key of imagination. Beyond it is another dimension: a dimension of sound, a dimension of sight, a dimension of mind. You’re moving into a land of both shadow and substance, of things and ideas. You’ve just crossed over into... the Social Media Zone.

any of us remember Rod Serling’s introduction to his television series The Twilight Zone, a science fiction anthology that captured our imaginations with suspense, a bit of abstract thinking, and unexpected epilogues. His introduction could very aptly apply to today’s social media phenomenon. The combination of imagination and technology has created a new media that travels around the world instantaneously and uncensored with revolutionary impact—socially, economically, and politically. With the advent of Facebook, Linkedin, Twitter, YouTube, Skype, Instant Messaging, and a plethora of other sites, social networking has become not only a tool for social interaction but also a window to world events. It has changed the world, simultaneously recording and broadcasting those changes as they happen.

As one of the fastest growing movements of the decade, social media is not “just for kids” anymore. Business leaders have also recognized the marketing potential of this valuable resource. According to a study by PR firm Burson-Marsteller (Global Social Media Check-Up 2010) of the 100 largest companies on the Fortune 500 list, 79% of them use Twitter®, Facebook, YouTube™, or corporate blogs to communicate with customers and other stakeholders. IFPS has taken full advantage of the opportunity and introduced itself to many friends on Facebook, has followers on Twitter, and is connected with 741 professionals on LinkedIn with as many managers as entry-level connections. Social media will be the key to “unlock the door of imagination” of young people and draw them into the world of fluid power.

The IFPS Marketing Committee is diligently working on a series of YouTube videos in an effort to attract individuals to the fluid power industry. YouTube offers a wealth of information from “Hydraulic Low Riders” to “Hydraulic Hybrids” and many examples of automation, motion control, and robotics applications. This has compelled us, at the prompting of industry, to develop additional training, education, and certification opportunities. Electronic Controls Specialist is our most recent certification. Electronic Controls for Technicians and Mechatronics certifications are currently in the development stages and should be released in late 2012 or 2013.

These avenues of knowledge are imperative for drawing in the next generation of fluid power professionals.

The Fluid Power Educational Foundation, strengthened through a closer alliance with IFPS, is continuing to play a major role in advancing and supporting fluid power education at all grade levels. FPEF has increased its efforts in developing key schools for the advancement of fluid power education and extending support to the academic community through competition involvement, scholarships, and mentoring programs.

As the economy rebounds, individual retirement accounts will recover as well. Baby boomers will once again contemplate retirement, and the tipping point between job vacancies and qualified applicants will be fast upon us. One of our primary goals is to attract individuals to fill those inevitable vacancies. Will we be ready when those opportunities arise, or will our epilogue be an unexpected “Twilight Zone” experience?

The industrial revolution

once pulled willing workers from the fields to the factories. Currently willing workers are pulling factories to China, Korea, Honduras, etc. A notable exception to the off-shore migration is successful automation. The capability of machines operated by knowledge workers shows continual increased productivity.

One recent example deals with the importance of maintenance information that can save hours of lost production: a pick-and-place feeder designed to lift wooden trim strips 2-inches wide and 8-feet or 10-feet long.

Six vacuum cup assemblies with independent vacuum generators are evenly spaced. These attach to the wood strip, which is lifted and pushed forward unto a conveyor that runs at 90 degrees to move the product in another direction. Occasionally a strip is dropped and entangled and halts production. Much of the data about force and motion went away with the machine designer.

Maintenance wanted to know where the weak link or links were. They wondered if the strips with textured decorative surface allowed vacuum leaks.

The time and cost of replacing all of the parts and pieces to fix the problems seemed an expensive and thoughtless approach. Since the machine has been in production for several years, the vacuum generators and vacuum cup sizes are probably okay.

I would trust, but verify. Part of the answer was two gauge assemblies, one for pressure and one for vacuum. One pressure gauge assembly with 6-mm

push-in tubing fittings showed the pressure to each venturi vacuum generator assembly (Fig. 1).

1. A plug-in gauge assembly and or pressure gauges in both ends of the supply line verifies that the pressure is maintained from inlet to the far side.

2. The vacuum test gauge assembly with pushin fittings can be plugged into each assembly to verify everything from the venturi vacuum generator, vacuum filter, and vacuum cup.

• For a benchmark, install a new vacuum cup, vacuum filter, and vacuum generator at one station.

• Use a smooth metal plate for the vacuum cup to seal against.

• Record this vacuum level and periodically test the used assemblies to see how much they may have deteriorated.

• With a poor performing station, isolate individual components by replacing them one at a time and testing the affect.

• By recording the approximate duration of service of each item, preventative maintenance can replace items before they fail without wasting a great deal of service life.

• Keep the gauge assemblies in a box attached to the machine for the next time and the next.

It was very interesting that $15 invested in a vacuum gauge tool including convertible fittings could provide the information to know what to do and when to do it to avoid lost time and product damage.

fluid power Case study

Why The Cylinder Moves Slowly

By Mikel Janitz, Muncie Power products

In the test lab, the environment and variables are controlled, and skilled engineers and highly trained technicians carry out the testing. The test process and equipment are controlled with special tools, gages, and protocols, unlike in the real world with field applications where there are many unpredictable variables and alternatives to manage.

The following is a case study about a customer whose truck was not working because the cylinder was moving slowly.

The vehicle was brought into the high bay test lab where the team could get out of the cold weather and focus on the situation. This allowed two things to happen. Initially, it provided time for them to speak to the customer to understand the issues. Secondly, the truck had time to cool down so the team could get under it safely.

The customer had installed a pump and PTO, then plumbed it just like they always did. They started the truck and actuated the cylinder, but this time it moved way too slowly. This was not ordinary and very frustrating, not to mention time consuming, for the customer to debug. The customer anxiously wanted to know why and how the pump would be fixed or replaced. There were some more discussions in the lab about the truck’s equipment before the team formulated a plan.

The customer’s reaction to the situation was not a surprise. They thought there was something wrong with the pump or the power take-off. Was the pump not pumping correctly or was the PTO’s output shaft not spinning fast enough? The owner of the truck and his mechanic both stated they used the same pump and same set-up each time before. They used all the same parts every time and couldn’t imagine why it was not working. According to the mechanic, they turned up the pressure on the relief valve, but the cylinder still moved slowly. The team took that piece of information to heart and noted it on the test sheet.

The truck was safely in the lab, so the test technician and engineers started working the plan. They decided to conduct two tests with the customer present to quantify the performance of the equipment. First

phase was the system check while the equipment was still on the truck as received (Fig. 1).

The second phase was a component level check with everything disassembled. The team carried out the system check first with all the equipment on the vehicle. While the test technicians started the first phase of work, the engineer continued with his. The first thing he did was to listen to the customer and take copious notes. This led him to reviewing basic principles of hydraulics: Flow rate is defined as volume per a given time period.

Normally flow rate is expressed in barrels per day, gallons per hour, or cubic feet per minute. Moreover, flow rate is not a function of pressure. Pressure is not part of the equation. Pressure is load per area (pounds per square inch). Armed with that knowledge, he discounted the observations made by the mechanic that turning up the pressure did not help to fix the problem. Turning up the pressure will never increase flow rate. This is a common misperception and could lead to unsafe operating conditions. Flow rate is directly proportional to inside diameter. Said another way, the larger the diameter of the system, the greater the flow rate possible.

Back in the test lab, the truck system checked out okay. The equipment seemed to be in good working order. The tachometer on the PTO was reading the appropriate RPM, and the output shaft was turning. The flow gage indicated the pump was pumping correctly, and the inline pressure gage indicated the pressure was reading within acceptable levels. Lastly, the mechanical linkage was checked out, and it was verified to be connected correctly and turning the right direction. With the system checks completed and quantified, it was onto the second phase of testing. The technician removed the hoses and disassembled the parts, pump, PTO, and cylinder. He then bench-tested each on a test stand in the lab. They all checked out, as well. No problems were found with the pump at all.

When the test technician disassembled the system, he looked at all the other components and in doing this, he observed the hoses and fittings closely used on the truck. The hose inside diameter (ID) was big enough, but the ID on the fitting at the cylinder looked smaller. After measuring the ID with digital calipers, it was discovered the fitting was a reduction fitting. It was nearly half the diameter of the hose. The test tech shared that with the engineer immediately. (Remember flow rate is vol-

Fig. 1: Test

ume per time. Volume is Length x Area. The area of the fitting is calculated by π x R2. Therefore, flow rate is directly proportional to the inside radius squared.) This was explained to the customer and his mechanic. We showed him that a small change in fitting ID can result in a noticeable change in flow rate at the cylinder. Hence, that is why the cylinder moved so slowly. With that information out in the open, the mechanic remembered grabbing the only fitting that would fit the cylinder, not realizing it had a smaller ID than the others before.

The third test in the lab was the last test. The equipment was put back as it was found, all the same except for a new fitting with the larger ID on the cylinder. The truck was started, the PTO engaged, and the pump started flowing, and as expected, the cylinder worked just fine.

Investing is a modern test lab is a good idea, and staffing it with skilled technicians is the right approach to solving problems. To make a long story short: With the new larger fitting in place, the cylinder moves at the speed it should.

Increasing pressure does not increase flow rate.

More importantly, increasing pressure is likely to damage the equipment. Before testing, it is always important to listen to the end user, test the system and components, and observe the equipment. Take a lot of notes, and take a few moments to study the situation so you can apply basic hydraulic principles to the situation. Don’t assume anything. Bench testing proves the parts, pump, and PTO work appropriately. Testing the system with the fix in place proves the system was mounted correctly. Observations and listening skills coupled with sound engineering practice solved the problem and allowed for a simple fix.

With this in mind, let us consider the pros and cons of the various hydraulic filter locations: pressure filtration – Locating filtering media in the pressure line provides maximum protection for components located immediately downstream. Filtration rates of two microns or less are possible, due to the pressure available to force fluid through the media. But filter efficiency can be reduced by the presence of high flow velocities, and pressure and flow transients, which can disturb trapped particles. The major disadvantage of pressure filtration is economic. Because the housings and elements (high-collapse type) must be designed to withstand peak system pressure, pressure filtration has the highest initial and ongoing cost. return filtration – The rationale for locating filtering media in the return line is this: if the tank and the fluid it contains start out clean, and all air entering the tank and returning oil is adequately filtered, then oil cleanliness will be maintained. The other advantage of the return line as a filter location is that sufficient pressure is available to force fluid through fine media (typically 10 microns), but pressure is not high enough to complicate filter or housing design. This combined with relatively low flow velocity, means that a high degree of filtering efficiency can be achieved at an economical cost. For these reasons, return filtration is a feature of most hydraulic systems. The main disadvantage of return line filtration is that the back pressure created by the element can adversely affect the operation of and/or damage some components.

Fig. 1: Effect of tensile forces acting on axial piston design.

off-line filtration – Off-line filtration enables continuous, multi-pass filtration at a controlled flow velocity and pressure drop, which results in high filtering efficiency. Filtration rates of two microns or less are possible, and polymeric (water absorbent) filters and heat exchangers can be included in the circuit for total fluid conditioning. The main disadvantage of off-line filtration is its high initial cost, although this can usually be justified on a lifeof-machine cost basis. inlet (suction) filtration – From a filtration perspective, the pump intake is an ideal location for filtering media. Filter efficiency is increased

www.fluidpowerjournal.com | www.ifps.org

by the absence of both high fluid velocity, which can disturb trapped particles, and high pressure-drop across the element, which can force migration of particles through the media. These advantages are outweighed by the restriction the element creates in the intake line and the negative effect this can have on pump life.

A restriction at the pump inlet can cause cavitation erosion and mechanical damage. And while cavitation erosion contaminates the hydraulic fluid and damages critical surfaces, the mechanical effect of vacuum-induced forces has a more detrimental impact on pump life.

The creation of a vacuum in the pumping chambers of an axial pump puts the piston-ball and slipper-pad socket in tension. This joint is not designed to withstand excessive tensile force and as a consequence, the slipper becomes detached from the piston (Fig. 1). This can occur either instantaneously, if the vacuum-induced tensile force is significant enough, or over many hours of service as the ball joint is repetitively put in tension during inlet.

The piston retaining plate, the primary function of which is to keep the piston slippers in contact with the swash plate, must resist the forces that act to separate the piston from its slipper. This vacuum-induced load accelerates wear between the slipper and retaining plate and can cause the retaining plate to buckle.

If this happens, it allows the slipper to lose contact with the swash plate during inlet, and it is then hammered back onto the swash plate when pressurized fluid acts on the end of the piston during outlet. The impact damages the piston slippers and swash plate, leading rapidly to catastrophic failure.

In bent axis pump designs, the piston is better able to withstand vacuum-induced tensile forces. Piston construction is generally more rugged, and the piston ball is usually held in its shaft socket by a bolted retaining plate. However, tensile failure of the piston stem and/or buckling of the retaining plate can still occur under high vacuum conditions.

In vane pump designs, the vanes must extend from their retracted position in the rotor during inlet. As this happens, fluid from the pump inlet fills the void in the rotor created by the extending vane. If excessive vacuum exists at the pump inlet, it will act at the base of the vane.

This causes the vanes to lose contact with the cam ring during inlet, and they are then hammered back onto the cam ring as pressurized fluid acts on the base of the vane during outlet. The impact damages the vane tips and cam ring, leading rapidly to catastrophic failure.

Gear pumps are mechanically the least susceptible to vacuum-induced forces. Despite this fact, research has shown that a restricted intake can reduce the service life of an external gear pump by at least 50%.1 Pump inlet or suction filters usually take the form of a 150-micron (100-mesh) strainer, which is screwed onto the pump intake penetration inside the tank.

In the 10 years I’ve actively campaigned against their use—for the reasons outlined above—I’m sure I’ve heard all the counter arguments. And most arguments for the use of suction strainers are premised on bad design, bad maintenance, or a combination of both.

The argument that suction strainers are needed to protect the pump from debris that enters the tank as a result of poor maintenance practices is a popular one.

The reality is nuts, bolts, tools, and similar debris pose minimal threat to the pump in a properly designed reservoir, where the pump intake penetration is located a minimum of four inches off the bottom.

Of course, the proper solution is to prevent contaminants from entering the tank in the first place.

A similar argument asserts that suction strainers are needed to prevent cross contamination where two or more pumps share a common inlet manifold. Here again, if suction strainers are necessary in this situation, then it is only due to bad design: the manifold must be below the pumps’ intakes. If properly designed, there should be a head of oil above the inlet manifold, and the inlet manifold should be above the pumps’ inlet ports. For cross contamination to occur in this arrangement, debris would have to travel uphill—against gravity and a positive head of oil, something which is highly unlikely.

But even in situations where a suction strainer is mandated—for whatever reason, the problem is: the cure can actually be worse than the disease.

tech tips

Hmmm…Did I torque those bolts? Am I sure I got ‘em all? It’s a common question when rebuilding anything that requires nuts or bolts to be torqued to a specific value.

Here’s a quick, easy tip that works every time. Take a cotton ball or piece of seat cushion foam and stuff it into the socket attached to your torque wrench. Soak the cotton or foam with RED machinist’s Dykem® or any other kind of ink that will leave a mark on the nut or bolt. When the socket contacts the fastener, it will leave an ink spot on the fastener, and you’ll know you’ve put the torque wrench to it, alleviating any doubt that ALL the fasteners were torqued.

Fluid Power Journal is looking for Professionals in the industry to submit small blurbs (2-3 paragraphs) to help readers troubleshoot common problems and challenges. Contact Kristine Coblitz at kcoblitz@fluidpowerjournal.com for more information.

Hydrostatic transmission components today are of such high quality and efficiency they don’t allow enough exchange of oil in the loop to keep temperatures at an acceptable level. This is especially true if the transmission is heavily loaded during its work cycles. The oil simply goes from the pump to the motor or motors and back to the pump without getting a chance to return to the reservoir to cool and relax. Using a hot oil shuttle or loop-flushing valve can help remedy this situation.

One common mistake to look for when troubleshooting a circuit that has one of these flushing devices but still seems to be running over temperature is the improper setting of the shuttle valve relief cartridge.

When the transmission is in neutral, the connection to the low-pressure shuttle relief is blocked.

The flushing valve at this point has no function, and charge pressure is controlled by the charge relief at the pump. When the transmission is operated either in forward or reverse, the low-pressure relief in the flushing block should now see the low side of the circuit, and if properly set, 30-45 psi (2-3 bar) below the charge pump relief will direct oil from the closed loop back to the heat exchanger and tank. *Make sure to always verify the setting value of the shuttle relief. This will still provide sufficient design pressure to satisfy critical machine function needs such as brake release, two-speed shifting, etc.

Things to remember if you are an equipment/machine maintainer, whether industrial, mobile, or even pneumatic: • When selecting a replacement hose, consider application, pressure range, and fluid to be conducted.

• Compatible hose fittings must be selected to match the hose manufacturer. According to ISO 171652 (2006) section 6, “Hose from one manufacturer and hose fittings from another manufacturer shall not be intermixed without approval from both manufacturers.”

• Ensure the bulk hose you select meets the requirements laid out in ISO 17165-2 (2006) Paragraph 9.2.2.

• During assembly, most manufacturers recommend that hose insertion depth be marked.

• After using the proper crimper, the crimp diameter should be measured to ensure that the manufacturers’ specification is met.

• According to manufacturers if the proper hose is used with the proper fittings and crimped to the proper manufacturer specification, you can forgo proof testing as all manufacturers proof test hose runs when the bulk hose is made.

Thus, select right, assemble right, install right, and you will be safe.

Low Vacuum High flow Figure 1

Figure 5

january/february 2012

Figure 2

Figure 4

Vacuum generation equipment of all types is able to provide this, but only a few are actually designed for this purpose. For example, a vacuum generator or venturi as shown in Fig. 2 is a very simple, low-cost vacuum generation device. Sometimes referred to as a “pump,” which it is not, the vacuum generator, venturi, or ejector (all the same device) is powered by compressed air at a pressure, depending on their design, between 40 and 90psi(g). Depending on the inlet pressure, the type of venturi nozzle(s) and the nozzle(s) diameter, the induced vacuum air flow will be determined.

Fig. 3 shows a graph comparing a vacuum generator (Fig. 2) and a vacuum pump, which in this case is a regenerative blower (Fig. 4). As shown on the graph, both the pump (RED line) and the generator (BLUE line) start producing approximately the same amount of flow at a free air flow condition of 0"Hg (nothing attached to the inlet). As the vacuum level increases (work piece being clamped), the pump maintains a stronger air flow volume than the generator. At 9"Hg, which is a significant vacuum level for a CNC router, particularly for larger pieces, the pump has more than double the flow capacity than the generator.

Furthermore, the pump uses a 3.4-hp motor whereas the generator would require a compressor of about 7-hp to generate the compressed air required—a considerable difference.

Daniel Pascoe is General Manager The generator in this example has a final vacuum of Vacuforce Inc, manufacturer and of about 22"Hg, whereas the pump has a maxidistributor of vacuum components and systems for industry in North mum vacuum of only 15"Hg in comparison. But as America. Daniel can be reached at stated before, in this application a router table rarely www.vacuforce.com or directly at dpascoe@vacuforce.com.

Consequently, from this example, which is a typical performance comparison of the two techwww.fluidpowerjournal.com | www.ifps.org

Figure 3

ost vacuum pick-and-place applications require a moderate vacuum level of about 20+"Hg. For example, a 40-mm diameter cup has a theoretical lifting force at this vacuum level of about 17 lbs. This is of course affected by numerous conditions such as inertia and surface type.

There are many options the user may choose from regarding a vacuum generation device, and in most applications where the surface is relatively non-porous, the flow rate (pump capacity) is not the primary consideration. There are many vacuum pumps (motor or pulley-driven equipment), single and multi-stage ejectors (generators) to choose from, and most of these devices offer a suitable vacuum level for pick-and-place applications. Of course the actual application will determine what exact type should be used, and in this article two are compared: compressed air-powered generators and regenerative blowers for use in low-vacuum applications requiring high flow rates—completely different technologies for completely different applications.

When using vacuum for applications that require a large volume of flow, the options for vacuum generation should be considered more carefully. In applications where material is being held down, for example, such as MDF (medium density fiber) board or plastic sheets on a CNC router (Fig. 1), the amount of vacuum required is low due to the large surface area of the parts being clamped. However, a large amount of vacuum flow is required due to the inevitable high amount of leak paths around the work piece area or through the machine’s own MDF (porous) vacuum table, where the work piece is being clamped.

Therefore, the selection criteria for correct vacuum generation equipment is clear: the user requires low vacuum and high flow.

nologies, the regenerative blower (Fig. 4) has a distinct advantage. Of course the air-powered generator is smaller, weighs less, has potentially a lower cost to procure, and is more mobile, but fundamentally it is not as suitable or as efficient as the blower.

Low-vacuum/high-flow applications are very common in such tasks as the printing industry where paper is being transferred with perforated rollers, plastic film positioning plates, material conveying, grain hoppers, and as shown in Fig. 5, multiple vacuum cup handling devices. The multiple cup head shown in Fig. 5 is a good example of where high vacuum is not required.

If the head is maintaining a vacuum level of only 6"Hg during the pick-up phase and there are 24 cups of Ø40 mm, then this head has a holding capacity of over 126 lbs.—more than enough for the majority of applications this would be used for.

If something needs to be lifted or held down, the fundamental requirement is vacuum force. However if the seal is poor or continuously leaking, then more vacuum FLOW is required to compensate for the leakage and maintain a safe working vacuum level.

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.

Safety Focus

Plan, Train, and Maintain for Safety Success

Safety discussions often lead to conversations about which rules and regulations will drive us to a zero-injury workplace.

The issue is that many workers know the rules and regulations yet do not know how to apply them to achieve the goal that nobody gets hurt. If we measure safety success by how many injuries occur, it could be as King Solomon stated, “...we are

just chasing the wind.”

by Carl Potter, CSP and Deb Potter, PhD

Numbers are elusive. Many companies attempt to reach some industry benchmark such as “top quartile” or “best in class.” The difficulty is in the comparison, and many groups spend much effort making sure they are using the same types of measurements. A review of work teams, divisions, and companies that have the lowest number of injuries as well as an overall safety process, we found that they measure their success around three areas that can be measured and improved: planning, training, and maintaining.

Planning Dr. Stephen Covey says, “Begin with the end in mind.” Describing what the ultimate goal is can be difficult for some organizations – particularly if the goal is not stated in terms of a number. Determine what safety success looks like in your company. Then determine what the gap is between the current state of safety and

Circle 351

20

january/february 2012

the desired results. Bridging the gap is what planning is all about. Many times companies are just throwing ideas “against the wall” to see what sticks. This just upsets everyone involved because it feels like the “safety program of the month” – everyone gets confused on what the emphasis is at any time and people give up trying to keep up with the latest “new idea.”

Planning is not the easiest part of safety because it takes work. Identifying where you are in the process by conducting a formal hazard assessment (FHA) is a good place to start. This assessment results in the identification of hazards that must be targeted for risk mitigation. Once you know what to mitigate, plans should result in a budget of time and money to address the issues. Mitigating hazards in the workplace is a fundamental process in creating a zeroinjury workplace. A key tool for reducing risk is the development of skills through a solid training process.

Circle 352

www.fluidpowerjournal.com | www.ifps.org

Training Training for safety success goes beyond what many organizations refer to as “mandatory compliance training.” It also goes beyond corrective action. Have you ever been sent to training because you failed?

Maybe you had a vehicle incident and your boss sent you to defensive drivers training. This is a typical reaction of many companies and, without realizing what they have done, employees are put on the defensive because the training is viewed as punitive.

Consequently, little actual learning takes place. Other times, training seems like punishment because of the trainer’s lack of ability or knowledge of the subject.

The primary thought of most employees is, “This is a waste of time.”

Carl Potter is a board-certified safety professional (CSP) and a certified management consultant (CMC).

He may be contacted at carl@potterandassociates.com.

Deb Potter, PhD, is a certified management consultant (CMC), and specializes in safety management for high-industry. She may be contacted at deb@potterandassociates.com.

Most skilled professionals value training. When training is delivered in such a way that allows the participant see why they need it, then they are open to learning. To be effective, the training must be at a level that is not below their current knowledge. It is fine to review basic concepts, yet maximum learning takes place when participants are challenged with new concepts and applications. Training must be purposeful and not left to chance. Just like machines, people must be maintained, and training cannot occur only on rainy days and when the company has time.

Maintaining Maintaining skills in a professional environment is crucial to creating a zero-injury workplace. When a skilled worker continues to work day-in and dayout without perfecting and honing his or her skills, complacency sets in. Highly skilled workers can get into bad habits and become over confident, leading to injuries when skills are not maintained through purposeful training. Imagine professionals such as doctors that studied their work in college and never returned to a learning environment for 10 years.

Would you want your family to see such a doctor for a medical crisis? Make sure that you take responsibility for not only your technical skills, but also your safety knowledge. New techniques and applications can help you maintain yourself for safety success.

Safety Focus

Move Yourself Forward for Safety Success If you work as a skilled professional in a high-risk environment, consider planning, training, and maintaining for your personal development. Where do you want to be 10 years from now in your career? Where are you today in relation to where you want to be? What training could you do to improve your chances of being where you want to be in 10 years? How long has it been since you have been in a position to maintain your skills?

Plan your future, but plan your next move, too.

At the beginning of each job, plan your work so that you or anyone else will not be injured. Train yourself to know the rules, follow the rules, and learn why the rules exist. Then maintain your competency as a skilled professional and don’t wait for your company to maintain your skills; take control and make sure you are the top hand who targets high-quality work and hits the target: Nobody Gets Hurt on each and every job. This is the measure of safety success.

The lube engineers' forum

Selecting An Automatic Lube System: Injector, Single Line, Or Dual Line

T

here are three (3) basic types of automatic grease lubricating systems: parallel injector blocks, single line progressive (cascading), and dual line parallel.

SELECTING A PROGRESSIVE OR PARALLEL SYSTEM One parallel system advantage is if a single delivery component fails or is blocked, the rest of the system will not be affected. Also, parallel systems adapt well to very long and fairly straight piping runs as can be found on a paper machine or a steel rolling mill.

A progressive system is more readily adaptable to a plant floor-mounted machine such as a printing press, folder-gluer machine, bottling plant palletizer, or a metal forming press. In a progressive system, when a line is blocked between the valve and a bearing, everything beyond that point in the system shuts down. If you were feeding six (6) bearings from one (1) distributor block (designated as A, B, C, D, E, F) and A, B fired but C was blocked, the following cycle would include grease distribution from A and B only.

Are the various lube points spaced regularly throughout the length of a long series of points? Or do you have randomly placed pockets of lube points, with each pocket having a different number of lube points?

In selecting the system type, consider whether you want the machine to continue running even if you lose a bearing versus whether you can afford to shut

By Wade Parks, WP Associates

the machine down and lose production rather than lose a bearing.

MOUNTING AND PIPING CONSIDERATIONS The second step is to discuss the piping and device mounting restrictions. How are the various lube points arranged, and what are the accessibility and environmental factors? What are the equipment and piping considerations with regard to local activity and environment?

The most efficient automatic lube systems have the distributor valve mounted close to the bearing, so the millwright must have access to the bearing and have a local structure for mounting the distributor valve.

The system component’s construction and piping materials selection range from polyurethane to stainless steel. Local shielding and cooling should also be considered. For example, a polyurethane system running in a covered cable tray may be less expensive than stainless steel tubing.

A local, ventilated pump and control house mounted below a crusher conveyor may be less expensive than replacing damaged pumps and controllers. Don’t mount pump and controller close to the lime kiln or boiler.

FINALIZING EQUIPMENT SELECTION A third consideration is the quantity or dosage amount required for each lube point and whether

Figure 1

Figure 2

22

january/february 2012

www.fluidpowerjournal.com | www.ifps.org

these dosage amounts are of a generally common displacement size or whether there is such a wide variance in dosage amounts required that the disparity precludes the use of single size limited range, lube displacement components.

Most injectors, as well as single and dual line delivery valves, are adjustable within a specified range. Most manufacturers have equipment available to cover an overall range from 0.003 to 0.300 cubic inches (in3) per outlet per cycle. Typical single valve ranges include 0.003in3 to 0.050in3 per outlet, 0.015in3 to 0.150, and so on, finishing up with something like 2.500-3.00in3 per outlet.

Guidelines for lube quantity selection (film thickness) include one thousandth of a cubic inch of grease per square inch of lube surface area, every two hours (WP Associates), and OD (mm) x width (mm) x 0.002 = cc/week grease (SKF). Note: cubic centimeters (cc) = cubic inches x 16.39.

Given the desired quantity of 700 cc per week, we would suggest breaking that down into a frequency and duration that will produce a delivery of 50 cc every twelve (12) hours.

INJECTORS A parallel injector system (Fig. 1) may include a single injector per supply line, or distributor blocks of up to ten (10) injectors per supply line. A distributor block requires only a single inlet connection for grease supply for up to ten (10) injectors.

Figure 3

The objective of the Lube Engineer’s Forum is to provoke thought and dissimilate ideas throughout the user industry.

WP Associates has been a contributor toward this endeavor for many years but is always looking for lubrication engineers to ask a question or provide intelligence. We need you!

Stay Connected... with your system partner for control cabinet products, field bus and distribution systems and connectivity solutions for your I/O control.

We encourage your input and will consider using your proposed or problem application in a future LUBE ENGINEER’S FORUM article. Contact Wade at wpassociates@plantationcable.net.

An injector is a grease supply, pressure and flowoperated piston that discharges a metered amount of lube and refills the charge chamber with the grease that is beneath the piston at full discharge stroke. The system requires a vent valve to relieve the pressure on the injector piston, allowing the spring to retract the piston and refill the charge chamber. A solenoid valve is required for starting and running each programmed cycle. The vent valve resets the system to be ready for the next cycle. The programmable controller will set frequency and duration of cycles, and operate all solenoid valves and vent valves.

This system employs an air-operated grease drum-mounted pump, with typical drum capacities of 120# or 400#. Drum size should be predicated upon drum refill schedule selected, governed by usage expected. Refill should be scheduled for a maximum duration of three (3) months. Leaving grease in the drum for longer than three months may cause the grease to break down and lose lubricity, and may also result in thickening, causing pumping problems.

SINGLE LINE PROGRESSIVE SYSTEMS A typical single line progressive lube system (Fig. 2) will involve several divider valves. Grease will be pushed through a series of dividers and will be distributed to bearings in a cascading method.

Each outlet will depend upon the previous valve having performed.

Single line systems are basically inexpensive, but have limits. They are not designed to lubricate machines that must run 24/7. Single line progressive systems are designed for such as metal forming machines, palletizer lines, or punch presses.

A menu-driven programmable controller and timer will set frequency and duration of cycles.

Remember that small amounts of grease applied frequently offer more efficient lube than do large amounts applied less frequently. Refer to desired film thickness as noted above.

A single line progressive lube system consists of a drum-mounted pump with drum cover, a primary distributor valve feeding several secondary distributors, level and cycle switches, a solenoid valve, and the programmable controller.

DUAL LINE PARALLEL SYSTEMS Dual line systems (Fig. 3) are selected when continuous duty service is required for a large number (20+) of lube points. Additional lube points may be added in the future with no system re-design. A single outlet to bearing blockage will not affect the other outlet’s performance.

Dual line systems are available with individual lube point indicators to verify lube and are typically volume adjustable even after start-up.

Dual line systems may be air-powered or electric motor-driven, with the programmable controller managing frequency and duration of each cycle.

Air-powered systems should include a filter, regulator, and lubricator package before pump air inlet.

A manually operated pump with lever handle, or a grease gun, may also be used in these systems.

Manual pump or grease gun displacement per cycle is a consideration when planning for selected film thickness.

Distributor valve pistons are cycled and replenished by pressurizing alternate inlets to the distributor through a reversing valve. A grease strainer is suggested prior to the reversing valve.

Some dual line valves have two (2) outlets that can serve two (2) bearings, or which can be cross-ported to serve a single bearing with greater frequency. Other dual line valves have a single outlet. Both types are replenished and activated by alternately pressurized inlet lines. Dual line distributors are typically available in blocks of one to four valves.

The dual line programmable controller should be equipped with remote visual system status reporting using panel mounted LED’s. Also included will be (2) relays providing a 110 VAC output to a warning light or buzzer, and a 24 VDC output to the mill-wide control system.

WP Associates is recognized as a qualified automatic grease lubrication systems designer, but is only one of many listed internationally. We recommend that you utilize the expertise of one or more of these systems’ designers when considering a new or retrofit application. Designers and lube system distributors may be found under manufacturer names such as Bijur Delimon, Lincoln, and Trabon.

The first EEHPC,

held November 16 and 17, 2011, offered a full day of practical training in energy efficiency improvements for fluid power along with a second day focused on developing industry-wide strategies to support research and incentives to improve fluid power efficiency.

30

january/february 2012

Organized by the National Fluid Power Association (NFPA), the Fluid Power Distributors Association (FPDA), and the International Fluid Power Society (IFPS), the conference drew more than 100 registrants. Day one of the conference featured breakout sessions designed specifically for mobile hydraulics, industrial hydraulics and pneumatics. Hydraulics sessions focused on improving energy efficiency with electronic pump controls, proper component sizing, improved power unit design, hydraulic fluid selection and more effective use of energy storage.

Sessions for pneumatics emphasized proper sizing, lubrication, “effective conductance,” and methods for determining energy loss in pneumatic systems and components. They also highlighted the essential features of air audits and the importance of making proper use of the audits—including appropriate compressor adjustments to realize savings from demand side adjustments.

A complete list of EEHPC presentations and handouts are available for download at: http://www.nfpa.com/ Events/EEHPC.htm.

On day two, NFPA hosted a smaller discussion forum designed to allow fluid power manufacturers, distributors and customers to interact and assess the needs of key end-use markets that rely on hydraulics and pneumatics. Several positive outcomes resulted, including a working group that will help NFPA update and refine the precompetitive research agenda it created for the fluid power industry as part of its 2009 Technology Roadmap project.

Energy efficiency will endure as an essential research challenge for the industry, and a second NFPA-hosted discussion form explored this topic more deeply on the afternoon of the second day. Preliminary results from a comprehensive study of energy consumption by fluid power systems were presented, and participants discussed several proposals for reducing energy consumption through best practice procedures and more effective use of current technologies. The discussion helped frame the essential points of a broader energy efficiency initiative being considered by the EEHPC organizers—NFPA, FPDA and IFPS. Overall, the EEHPC was a great success. It served as a unique education opportunity for energy efficiency, as well as a springboard for further cooperation among industry associations and related stakeholders.

allowed Air Hydro to bring previously farmed honing work back in-house, helping it regain control of job turnaround times and save money on outsourcing.

Sometimes the best way to get a job done right is to do it yourself, especially when it adds to your bottom line, trims turnaround time, improves the ability to salvage damaged hardware, produces higher quality, and increases worker safety. Air Hydro Power proved the wisdom of this old axiom when it acquired a Sunnen HTA horizontal tube hone to repair and recondition hydraulic cylinders. Adding the honing machine to its repair shop tool lineup allowed Air Hydro to bring previously farmed honing work back in-house, helping it regain control of job turnaround times and save the company thousands in outsourcing costs.

Air Hydro Power started in 1961 in the founder’s basement, but quickly established itself as a major player in hydraulics by becoming the third Vickers distributor in the U.S. in 1965. Its repair division services and repairs all brands of industrial and mobile hydraulic pumps, motors, valves, and cylinders. Work in the repair shop is primarily focused on refurbishing steel

hydraulic cylinders used in construction equipment, materialhandling equipment (forklift trucks, telehandlers, and lift-gates) and heavy industry (cranes, oil rigs, off-road vehicles).

When Air Hydro Power’s Perry Goldstein assumed leadership of the repair division in 2007, in-house honing capability consisted of hand honing with a half-inch chuck Milwaukee drill. “Hand honing was physically demanding and a little tricky,” said Goldstein, Air Hydro’s Director of Value Added Services. “If someone accidentally hit the reverse switch while adjusting the hone, the stones would bite the tube and rotate the drill, which is not good if you’re the one standing next to it.” Other factors, such as inability to maintain stone pressure and having to deal with blind bores, relegated the company’s in-house honing to low-end tasks such as taking out light scratches, deglazing, or polishing.

“Correctly honing a tube, maintaining accurate diameter, and keeping all the taper out, is really difficult to do by hand,”

NFPA – National Fluid Power Association

NFPA Innovation Award Recognizes Gen-Tech Global Diesel Engineer Erling Skaar and Design Engineer Dr. Odd Arild Olsen Ph.D. NFPA recently recognized design engineers Erling Skaar and Odd Arild Olsen as the recipients of the first-ever NFPA Innovation Award given to individuals for using fluid power technology in innovative ways. Skaar and Olsen received the award for their unique design of an energy-efficient controller that also reduces the carbon footprint of marine vessels.

This add-on hydraulic technology reduces emissions dramatically by offering a power-generation system that eliminates the need for a second diesel engine—reducing fuel consumption and scheduled maintenance. Recipient Erling Skaar explained, “The key component is a controller that monitors electricity loads throughout the ship and communicates the information to the hydraulic pump.”

The hydraulic pump is driven by the vessel’s main engine, which maintains a constant hydraulic flow to the hydraulic motor independent of engine speed. To view a video of the system in action or for more information about the innovative technology, visit www.gentechglobal.com.

Multiple applications for the award were reviewed by an NFPA Innovation Award committee comprised of marketing professionals from several NFPA member companies. In its review of the Gen-Tech application, the committee acknowledged that the anticipated cost-savings from using a hydrostatic drive to control and power a generator vs. a second engine will make this application very attractive to many cost-conscious and eco-friendly marine vessels.

The NFPA Innovation Award recognizes individual design engineers in industries that use fluid power technology who compete to receive a monetary reward for their efforts in designing innovative fluid power applications. The goal of the program is to increase the visibility of fluid power in key industries.

CCEFP – The Center For Compact And Efficient Fluid Power

CCEFP Research Takes Aim at Reducing Friction in Fluid Power Systems

F

riction between lubricated surfaces is a principal source of energy losses in fluid power systems—a ubiquitous problem for fluid power users across the industrial spectrum. But thanks to research underway within the Engineering Research Center for Compact and Efficient Fluid Power (CCEFP), that problem is on its way to resolution. Led by Professor William King, researchers at the University of Illinois at Urbana-Champaign are developing low-cost, microstructured surfaces having a significantly reduced coefficient of friction compared to surfaces with a conventional surface finish.

“This research allows us to design and then manufacture microstructures onto a surface that will dramatically reduce the coefficient of friction,” according to William King, College of Engineering Bliss Professor at the University of Illinois.

It has long been known that when rough surfaces slide against each other, the roughness causes reduced friction. The reduced friction arises from hydrodynamic effects caused by the roughness. Before now, it was not possible to harness this effect for industrial applications.

“We have combined two new technologies,” says King. “First, we have created a computational design tool that lets us start with the application parameters— machine speed, lubricant type, and so on—and choose the optimal microstructures. Second, we have developed a low-cost manufacturing technique to put these microstructures onto machine components.”

Using techniques they developed, Dr. King and his team have fabricated these patterns on large surfaces of different shapes including curved surfaces. This technique has been extended to many metals including stainless steel, cast iron, nickel alloys, and tool steels.

Professor King and his team are interested in working with companies who may have applications in mind for their research findings. For further information, see www.ccefp.org, project 1D (Micro-and Nano-Texturing for Low-Friction Fluid Power Systems), or e-mail Dr. Stelson, CCEFP Director (kstelson@umn.edu) or Dr. King at wpk@illinois.edu.
