MOOCs and the Future of Fluid Power Education FLUID POWER IS an important enabling technology for mechanical, agricultural, and aerospace engineering. These disciplines graduate over 20,000 engineers a year, and every one of these graduates should be familiar with fluid power as part of their degree program. However, access to fluid power education is an enormous challenge at the university level. This challenge must be addressed, since familiarity with fluid power is important for all engineers, not just those working in the industry. Potential applications of fluid power exist in nearly all industries, and it is important to have well-educated potential users. BY KIM A. STELSON, PROFESSOR AND DIRECTOR, CENTER FOR COMPACT We at the Center for Compact and Efficient Fluid AND EFFICIENT FLUID POWER (CCEFP) Power are committed to greatly expanding access to fluid power instruction. To help address the need, we have made fluid power videos available to the general public (www.ccefp.org/education-outreach/public-outreach/fluid-power-documentary), and have created a collection of open courseware at the university level, including lecture notes, mini-books, and videos of lectures (https://sites.google.com/site/fluidpoweropencourseware/ material). Our two popular mini-books, “Fluid Power System Dynamics” by William Durfee and Zongxuan Sun of the University of Minnesota and “The Electrohydraulic Servovalve Coloring Book” by Rosamond Dolid of MTS System Corp., are available in downloadable PDF form for free or in bound form for a modest fee. In spite of our best efforts, however, the expansion of fluid power education has been slow. Recently, a new and exciting approach, MOOCs, have emerged as a way of greatly expanding educational access. MOOC stands for Massive Open Online Course, and it is not unusual for a MOOC to have more than one million students. The University of Minnesota and CCEFP are developing a university-level fluid power MOOC entitled “Fundamentals of Fluid Power.” The course will be first taught in September of this year. The instructors are Will Durfee and Jim Van de Ven. The course is free and available to anyone, anywhere in the world. You can learn more from the Coursera link to the course: www.coursera.org/course/fluidpower. Please help us spread the word to those who may benefit.

CCEFP is a National Science Foundation Engineering Research Center established in June 2006. It is a network of researchers, educators, students, and industry working together to transform the fluid power industry—how it is researched, applied and studied. In addition to its grant from NSF, the Center is supported by its seven participating universities and more than 50 industrial partners. Visit www.ccefp.org.

he International Fluid Power Society (IFPS) has dedicated June 19 as “Fluid Power Professionals' Day” - a day of recognition for all of us who work in the fluid power field!

PHOTO CONTEST IFPS is also hosting the first-annual Fluid Power Photo Contest! Look for the winners in the July/August issue of the Fluid Power Journal.

CELEBRATE THE DAY

WHY JUNE 19TH? A little bit of history behind the date is interesting. Blaise Pascal—a French mathematician, inventor, writer, and physicist—was born on this day back in 1623. His work in hydrodynamics and hydrostatics, including the invention of the hydraulic press, paved the way for all future innovations. He was also instrumental in experiments in pneumatics that examined the behavior of air in a vacuum and validated the work of the man who invented the barometer, Evangelista Torricelli. Because of Blaise Pascal and his work, the scientific foundation of thermodynamics and fluid power was set to build upon for those who followed.

Take the time to celebrate with your friends and colleagues in the industry. Here are some suggestions on how to celebrate the day; however, it’s “Your day to celebrate your way!” 1. WEAR emblems, pins, badges, and shirts noting your fluid power affiliation or organization. 2. TREAT your staff/co-workers to a pizza π. 3. PLAN a picnic or company cookout – include practical hydraulics with a squirt gun battle! 4. TAKE your employees to an amusement park or raffle off an admission ticket. 5. DISTRIBUTE this flyer to your local customers and/or fluid power vendors. On June 19th deliver goodies to those same locals who are displaying the flyer.

6. GO see a movie with hydraulics in action or go to a 4-D motion theater with moving seats. 7. NOTICE how many fluid power applications you can spot on June 19th on your way to work, to the beach, or wherever you are driving, flying, or boating that day. 8. GIVE back to the industry! Help the next generation of fluid power professionals by making a donation to the Fluid Power Educational Foundation (www.fpef.org) to help support individual scholarships for students entering the fluid power industry and/or to the NFPA Foundation (www.nfpafoundation.org) to help build more fluid power educational resources at 2- and 4-year colleges and universities. If the fluid power industry has supported you in your career or business, please consider support of your industry by giving back and paying the generosity forward through a donation. 9.

CERAMIC AIR VALVES REDUCE MAINTENANCE COST

FIG. 1: Rexroth Ceram™ valves feature sliding ceramic plates, allowing them to survive harsh conditions and dirty air without “sticking.”

NEEDLE BEARING ASSEMBLY PILOT CHAMBER & PISTON

By AVENTICS Corporation (formerly Rexroth Pneumatics)

he story line has been repeated endless times: maintenance personnel have to deal with directional control valves that stop working far sooner than they should, slowing down or stopping production. The valves could be located in a harsh environment, like a tire plant or a foundry. Or it could be that the factory just routinely has poor quality “house” compressed air. The Rexroth Ceram™ valve, by using ceramic plates for basic sealing, can tolerate environmental conditions, such as corrosion, dust, dirt, and sand, that end up in an air line, far better than traditional spool design valves. These contaminants accelerate wear of rubber seals in traditional packed-spool valves and cause failure of lapped spool valves by getting trapped in the extremely close clearances. The ceramic plates in the valve—one static and one dynamic—shrug off contaminants. The plates are made of extremely hard aluminum oxide (rating approximately 9 on the Mohs hardness scale, which rates diamond as 10). The plates are ground extremely flat – within a few light bands – and form a nearly perfect seal. Slots in the plates direct air flow as the top plate is shifted, wiping them clean by cutting through contaminates that destroy ordinary valves. The plates are guaranteed for the life of the valve. Another frequent source of downtime and annoyance are air valves “sticking.” Sticking most often occurs after a machine has not been used for a period of time, thus the term “Monday morning blues” when production is delayed while someone goes around tapping air valves with a wrench or hammer to

DYNAMIC CERAMIC PLATE STATIC CERAMIC PLATE get them unstuck. The cause is rubber seals sticking from a “varnishing” effect of airline contaminates on the seals. The Ceram valves solve this downtime problem because the ceramic plates don’t stick.

HARSH ENVIRONMENT APPLICATIONS A mechanic at a paper mill shared his story. The very hot, wet environment was causing air valves to fail on the average of three weeks to a month, costing the mill a lot of money in lost production time. The valves were used to oscillate cleaning doctors to keep the rolls clean. The first Ceram™ valve he tried was a big success: “It has run for five and one-half years, 24 hours a day, 365 days a year, cycling every eight seconds, four seconds off - four seconds energized. We are down for routine maintenance a few times a year, but other-

wise it just keeps on ticking. Almost entirely now on all upgrades and new installations, we use nothing but Rexroth Ceram valves knowing that we are installing dependability.” Engineers at a tire manufacturing facility were faced with valves failing in as little as six months. A hot, dirty environment combined with contaminates, such as carbon black, were destroying the o-ring seals in their air valves and costing them money. A switch to the Ceram valves now mean their air valves last for years instead of months. Over the years, foundries have been a constant source of the valve’s success for obvious reasons. For example, a manufacturer of gray iron castings uses pneumatically actuated wire brushes to remove sand from molds after heat and moisture have baked the sand to the molds. Sand was finding its way into the air

valves and destroying the seals. Valves that cycled every three seconds were lasting only two weeks to two months, causing a constant source of downtime. A switch to Ceram valves solved the problem because the ceramic plates are harder than sand and self-cleaning. The initial valves used were still in use a year and a half later without failure when the application success was shared.

PCD Cross Section

LONG LASTING IN LESS DEMANDING APPLICATIONS Steel mills, concrete batching plants, glass plants, feed mills, rubber, and plastics are all examples of other industries where the valves have solved premature air valve failure. However, most of these valves are sold in industries considered more “normal” in terms of the environment conditions. That’s because they work great there, also. Any plant can have dirty air if airline systems are not properly maintained, and customers have found that installing the valves save them from untimely work stoppages. By being available in ISO sizes I through IV, with ratings from 1.1 Cv to 7.5 Cv, the valves cover a very wide range of applications. ISO standard 5599-1 subbases feature ¼" to 1" NPT or ISO G (BSPP) port options with many accessories, such as speed controls and regulators. Working pressure is 0 to 150 psi (can be externally piloted for low-pressure or vacuum applications), and the valves can operate with or without line lubrication. A large variety of valve operators, including solenoid and air pilot choices, explosion-proof, and intrinsically safe choices, etc., allow the valve to provide millions of trouble-free cycles for multitudes of applications in industry.

CONCLUSION The Ceram valve, with its sliding ceramic plate design, has proven to be an instant cost savings in thousands of industrial applications by reducing maintenance and downtime costs.

D RAN OM PICK AND PLACE In 90% of vacuum pick-and-place applications, the product being handled is a known size, shape, and weight. A packaging machine designed to pick up a 20-lb box is designed to do just that: pick up a 20-lb box, which will likely be in production for many years to come. Therefore, the choice of vacuum components is a very simple exercise. As shown in Fig. 1, this layout illustrates four boxes with the appropriate end-ofarm vacuum tool approaching from above. This tool uses four “zones” highlighted in blue, green, yellow, and red. Each one of these zones can be connected to a common vacuum source, such as a vacuum pump, or be connected to its own dedicated vacuum venturi—very easy and commonplace in palletizing applications. If this same machine has to handle different-size boxes, however, such as the layout shown in Fig. 2, then problems become apparent very quickly. As you can see, there are now eight boxes that equal the same overall length as the larger four boxes in Fig. 1, but the seams of the flaps (which may or may not be taped) and the gap between the eight boxes will now prevent the end-of-arm tool from successfully sealing against this load, particularly if there is only one vacuum source. If the box weight was only a few pounds, the box flaps were taped shut (enabling vacuum seal on boxes 1, 3, 5, and 7), and each zone had its own dedicated vacuum source, there would be a chance of success. However, the robot that this tool is attached to certainly wouldn’t be able to run at full speed, and this would most likely impact the throughput of the production line.

By Dan Pascoe, Vacuforce, Inc.

Fig. 3 shows the same tool now attempting to handle the same width of boxes as shown in Fig. 2, but the boxes have a different length. This end-of-arm tool would certainly fail in this scenario, as 50% of the cups on each zone are leaking, and the vacuum pump connected to each zone simply wouldn’t be able to keep up with the leakage from the exposed vacuum cups. The problem with this scenario of potentially infinite box sizes is that application engineers more often than not resort to an end-of-arm vacuum tool, such as the one shown in Fig. 4. This tool has a single vacuum venturi directly connected to each vacuum cup. Regardless of what cups aren’t sealing on the boxes, the cup that is sealed will gain “full” vacuum. These tools are very common in industry and do, in fact, work very well. Well, at least for the machine builder. The end-user, however, endures the ongoing ownership cost, which can be extraordinary. First of all, there’s the compressed air consumption. Let’s assume that each venturi uses 1.5 cfm. There are 32 units in operation. This equals a total air consumption of about 48 cfm, which equates to about 12 hp or 9 kW. Some would argue this number is reasonable and a normal cost of production. However, with two, three, or even more of these machines in production, it soon gets very expensive, indeed. You then have ongoing maintenance. This can be quite high. Fig. 5 shows an alternative method for handling multiple-size boxes. This system uses 90 vacuum cups instead of the 48 used on the aforemen-

tioned tool(s), which is nearly twice as many. This is like firing a shotgun. You’ll at least get something! With this type of system, you’ll certainly have cups seal on most of the box surface, but more importantly, cups that are not sealed properly will automatically close, isolating the individual cup from the rest of the common vacuum source. This particular tool uses what is known as a self-closing valve. Each cup is connected to the common manifold (five manifolds are shown in this example in Fig. 5) via a self-closing valve. The valve acts very much like a velocity fuse. Too much air flow will push a rubber ball against a sealing seat inside the valve and isolate that individual cup. When the vacuum is turned off (to release the load), a spring will reset the ball and allow the valve to reset.

This method ensures that cups that are sealed against the load will reach full system vacuum regardless of what cups are not sealing. This universal type tool also uses considerably less compressed air or vacuum pump motor power compared to individual venturi, as shown in Fig. 4. A typical tool with about 100 cups will use about 20 cfm, but if used with vacuum intelligence, which turns the vacuum venturi on and off depending on demand (vacuum system level sensing), it could use considerably less. This type of tool is a good solution for most palletizing applications that require a multiple-size load-carrying ability. Considerations should also be made for filtration to protect downstream vacuum components, such as control valves and pump(s), ease of connecting a vacuum pump hose to a robot tool compared to a compressed air line for vacuum venturi, time of assembly compared to a turnkey offering, and so on. The need for multiple-size box handling is becoming more and more common as factories try to minimize machine numbers used in their production facilities. Understanding what technology is available is, of course, very important in any machinery choice. The task of handling various-size loads is easy, but having the most cost-effective solution requires a bit more thought than simply choosing what will work. 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

Determining Root Causes

e have read hundreds of incident reports in which some of the injuries were minor to several incidents that resulted in multiple fatalities. There are some very good investigators out there, however, there are very few investigators who are experienced enough with hydraulic systems and components to drill deep into the root cause. Language is a critical key in relaying the information to the reader, which could be anyone from the manufacturer of the equipment to the prosecuting attorney. Technical terms must be correct and expanded to the length necessary for the reader to understand. A well-written report made up of many details and contributing factors will greatly assist in preventative actions. “Is this the actual root cause?” Many factors lead to an incident, and the use of the fish bone diagram is an effective assist tool in assembling the facts. Generally speaking, a hydraulic incident will most likely, but not always, have a combination of the following contributing factors: component failure, failure to control hazardous energy, worker disregard, and unsafe machine design. Being responsible for the best outcome, an investigator should always dig and dig, but foremost the investigator should always utilize subject matter experts. If a root cause investigation was only conducted by one person, we would have concern about how comprehensive the report may be. Company policy on incident investigations should include a “process of involvement,” meaning a minimum number of investigators and the knowledge each individual brings to the team. The team approach ideally is the most effective way to dig into root cause.

Q+A

HYDRAULIC SAFETY PROGRAM Hydraulics is simply a means of transmitting energy, and like all other forms of energy, there are associated hazards. Hydraulic hazards can cause injury, equipment damage, and environmental damage. Eliminating hazards and reducing risk requires a comprehensive process. HSAC recently assembled a complete hydraulic safety program, which is a process designed to eliminate hazards, reduce risk, and make personnel knowledgeable. This combined process is the most effective way to protect workers, protect equipment, and protect the company from hydraulic hazards. Eliminating hydraulic hazards can be achieved by first understanding the causes and effects. Next is identifying hydraulic hazards, then integrating controls and devices, followed by developing specific procedures and training. An Achieved Hydraulic Safety Program will contain some of the following elements: • Integrated safety devices and components to execute energy control for task completions • Integrated safety devices and components to protect equipment, environment, and personnel • Developed procedures for energy control for specific tasks • Awareness training and safe procedure training • Documentation for inspection, hazard assessment, and protocol Many elements are combined to build a full hydraulic safety program that will greatly reduce risk, and maintain reliability and long-term repeatability for equipment and personnel.

WWW.FLUIDPOWERJOURNAL.COM | WWW.IFPS.ORG

Every time our machine cycles, the hydraulic hoses flex considerably, so I know there is a lot of energy being transmitted through them. How do I eliminate risk for my personnel who are working close to the hydraulic hoses?

True, there is a high risk when exposed to hydraulic hoses. A hydraulic hose conducts energy, which is fluid that does work, and the resistance to flow generates pressure. The flexing of the hose is a result of spikes in pressure caused by resistance to flow. Should hose failure occur, the risks are impact from hose whip; fluid injection injuries; atomized fluid, which is highly flammable; associated equipment failure; slip hazards; and burns. Hose sleeves designed for safety, whip restraints, shielding, and guarding will reduce risk for workers. Failure can be reduced through training, inspections, and proactive maintenance programs. The Earth Moving Equipment Standard ISO 3457 and EN 474-1 state that “Hydraulic hoses containing fluid with a pressure of more than 5 MPa (50 bar) and/ or having a temperature over 50°C, and which are located within 1 meter of the operator, shall be guarded.” Every effort must be made to protect workers from hydraulic hose hazards.

Before Flaretite

Isolation ball valves are commonly used where the hydraulic power unit is used to supply hydraulic power to many machines throughout the mill. Hydraulic supply, return, and drain lines to each circuit can be isolated while allowing other machines to function. There are many issues that increase risk with this method of isolation. Let’s start with leakage. Ball valves are designed having seat seals that can fail; therefore, the control of hazardous hydraulic energy would be lost. Next issue is lockable ball valves; the locking mechanism must not allow any swing of the valve handle. I’ve seen small padlocks locked into mechanisms where it was possible to swing the handle enough to allow the valve to flow. Next issue, some bleed circuits for energy control in the isolated circuit may be affected if the circuit is not allowed to vent energy back to the reservoir if the drain or return line is blocked. Redundancy of isolation ball valves will reduce risk if this method of energy control is used. Also, it is very important that you verify zero hydraulic energy (flow creating pressure) beyond the isolation points. This means constant verification or a scheduled verification based on lapsed time over the period of the lockout. Be sure that the lockout procedure explains the importance of verification when using ball valves as a method of energy control.

FLUID POWER CASE STUDY

hen a hydraulic lift fails, the results can be devastating—especially when it’s a platform with people on or under it. The hydraulic lift can easily come crashing to the ground and injure both people and machines. The staff at an amusement park came to ChemTec in Deerfield Beach, Fla., wanting a solution for this danger so that if a hydraulic lift failed on a stage, there would be minimal damage to people and equipment.

ANIMATRONICS – SHUT-OFF VALVE ENSURES SAFETY OF PEOPLE AND EQUIPMENT

ENGINEERING FOR THE WORST-CASE SCENARIO

The staff at ChemTec saw that a similar problem had been fixed when dealing with emergency shutoffs in natural gas, so they decided to use an HPEFV series shut-off valve for the park’s hydraulic lift. They adapted the valve for hydraulic fluid and made it so that when even a drop started to leak, the shutoff valve would engage and capture all the pressure from the stage. It would then slowly let the stage down rather than letting it crash down violently. These valves are typically used to sustain about 3,000 psi,

but the stages needed a stronger response, so ChemTec adapted the valves to take closer to 6,000 psi. SAFE AND SOUND

The increased load capacity to 6,000 psi ensures that even in the worstcase scenario, everything comes slowly and safely to the ground. FOR MORE INFORMATION, VISIT WWW.CHEMTEC.COM.

Ê PIRTEK Kent has provided on-site hose repair service in Seattle, Wash., since 2006. In the fall of 2013, Owner Gabe Gilliam received a call from his customer at the Washington State Fair in Puyallup, Wash. They added a new attraction, a looping inversion roller coaster called the “Rainier Rush.” It is the only model of this ride in the United States. It will take riders over 60 feet in the air before catapulting downhill around wild loops, along wavy tracks and bendy curves. The roller coaster needed service to ensure maximum performance during the debut in September 2013. Mobile Sales and Service Technician (MSST) Ray Rios arrived on-site and immediately put his fall protection equipment on. First, he needed to inspect the equipment and prepare a list of necessary parts. Rios had everything he needed in his Mobile Sales and Service Unit (MSSU) to complete the job, which took six hours. Rios installed new hydraulic motors on the track just before the coaster cars would navigate the upside-down loop. Rios plumbed three motor pumps on this section to speed up the trains. He also installed a new electric control valve on a tank and plumbed it into the internal manifold with hoses. Rios measured, cut, and installed hose assemblies in various lengths and sizes. There were eight PFMU25 hose assemblies with JIC fittings and ferrules, and three 115-ft PFMU25 hose assemblies with JIC and NPTF fittings and ferrules. A variety of adapters were used, including JIC and NPTF elbows. Rios also provided a new custom mounting plate, check valves, and gauges. www.pirtekusa.com

STAY AHEAD OF THE COMPETITION WITH EFFECTIVE FLUID POWER PROPOSALS Win to Quote Ratio Increased By Factor of 7 Due to Proposals

10%

71%

you only submit cost quotes, you are competing on price alone. Most companies do not want to do that. A proposal is a sales document that tells the reader why you should be selected from the proposals or quotes received. One fluid power distributor improved its win-to-quote ratio from an estimated 10% to 71% when proposals were tried in place of cost quotes. This is a seven-to-one improvement. As a result of similar findings, many companies are now advertising for joint sales managers/proposal managers.

2. RISK IS AN EVALUATION FACTOR. Describe applicable work already completed. If you have similar components in production, describe them. Describe the company background in creating similar components. Cite the preliminary design review (PDR) and the critical design review (CDR) as risk reduction tools. Describe any computer modeling and prototypes planned.

By George Fling

1. USE GRAPHICS. Reading studies indicate that 75% of what we know is obtained visually. We forget 75% of what we hear within 24 hours. The message for proposals is that we should tell our story graphically to the degree possible. Prolific use of graphics will require fewer words in the proposal. Graphics include photos, drawings, line graphs, bar graphs, and pie charts. Before starting to write the proposal, consider these two questions: 1. What graphics will tell your story? 2. What proofs are needed to support your claims? Some proposal experts suggest that the ratio of graphics to text should be 50/50 (50% graphics to 50% text). Many sales managers think their company makes superior products and will claim they are the best at what they do, with no substantiation. It is human nature to doubt any claim made without substantiation. Graphics have two parts: (1) the picture and (2) an action caption. The action caption has a title and tells the reader what he or she is supposed to learn from the graphic. It tells the reader why the graphic was included. The action caption is often more difficult to create than identifying the graphic. Studies have indicated that color graphics are more influential than black and white graphics, and according to one proposal consultant, any graphic that

•

takes more than 30 seconds to understand is overly complex. Most proposals will require at least the following graphics: • A photograph of the product offered, if an off-the-shelf item. Include a drawing of the product if the item must be developed. A photograph of the facility in which the product will be designed and manufactured. The assumption is that the facility shows a modern, prosperous company. A photograph of the program manager responsible for the project. The manager’s resume should emphasize the projects he or she has successfully managed, rather than how he or she is a good designer. An organization chart indicating that the program manager reports to a high level within the manufacturer’s organization. The organization chart should also indicate the customer’s contact within the company. (Microsoft has several forms for creating organizational charts.) A Gantt chart schedule. One customer considered this to be the most important portion of a proposal in that it told him how long he could defer placing an order and still meet his schedule. He further said that obtaining a schedule from many large suppliers is difficult.

3. YOUR PLANNED PROGRAM MANAGEMENT WILL BE EVALUATED.

4. SELL THE BUYER AS WELL AS THE TECHNICAL PEOPLE.

You are not likely to require a management volume, but a section on management should be included in the proposal. Do you have a conference room in which meetings are held? How often will the status of the program be made? Are action items posted on the conference room walls with due dates? When problems occur, does the program manager have access to upper-level management? On major problems, it is expected that upper-level management will attend.

The buyer may see only a separate cost volume. However, he is a key part of the evaluation team. Convince the buyer that you offer the most value by extracting your benefits from the technical volume and including these in the cost volume.

FOR MORE INFORMATION: The author has many additional photographs to augment the points made in this short publication. The material was taken from a PowerPoint seminar that normally runs one day. He can be reached at flinggeorge@yahoo.com.

5. AUTOMATE THE PROPOSAL. Without some form of automation, it is possible to spend more on the proposal than the profit to be made upon the win. Microsoft’s Mail Merge provides one solution. Mail Merge requires two documents to be created: 1. A main proposal document in a format of how the final proposal will look 2. A data table containing the information about each customer and his/her application With the press of a single button, the two are merged into a proposal Create master Create data ready for editing. Using proposal table if-then statements, difEnter data ferent text can be printed for specific to match the component proposal being proposed. For example, different text might MERGE describe a compressor or a vacuum pump, either of Save with new file name which might be made by the same company. The Make edits two documents are used over and over as new proBind Proposal posals are created.

THE ICING ON THE PROPOSAL CAKE

Though outside the realm of graphics, the following have been known to be included in proposals: • Prototypes. One manufacturer submits a 3-D prototype of his pump with the proposal. That manufacturer feels this is important for the customer to be able to take the prototype to verify that it will fit within the system in which it will be installed. • Bookmarks. A bookmark is created as a bulleted list of the features provided by the component or system. The features are taken from the various segments of the proposal. This is a repetition of the reasons for selecting you. The bookmark can include a photograph of the company or the product. • CDs/PowerPoint Presentations. A CD can include a PowerPoint presentation for your contact to use in telling his or her boss why you should be selected. I once included a trade study of the pros and cons of using six small vacuum pumps versus using two large vacuum pumps in a test system. My contact used the CD to brief his boss as to why he chose to go with the system recommended. One proposal consultant included a video citing the virtues of his proposed system to present to management. Many companies have a proposal form that is used by management in determining whether or not to bid. These forms usually require that there are strong reasons to think you can win the contract. I do not recommend proposing against an incumbent unless it is known that

the customer is unhappy with the incumbent. Even then, you are at a disadvantage in that the incumbent has probably performed much analysis under contract that you propose to do after your win. This difference is a risk to the customer in selecting a new supplier. The risk is a possible schedule delay and possible growth in size of the component. I also recommend against making unsolicited proposals. I have seen proposals with analyses ranging from 12 to 38 pages. The predominant type of analysis included in proposals is a stress analysis for a proposed component. The military

services frequently require analysis of various types. They often grade you poorly if the analysis is to be done after award rather than before proposal submission. Need more evidence that proposals should be part of your marketing efforts? One non-fluid power company had approximately 1,100 salesmen and saleswomen. A 22-year-old salesman became the top salesperson at the company. His secret? He created a proposal for every company product. When an opportunity arose, he pulled the proposal from his computer and tailored it to the particular customer and his requirement.

RETHINKING

BY DAN HELGERSON, CFPAI, CFPS, CFPECS, CFPMT, CFPSD his article will take a look at three alternatives to the traditional reservoir. First, we will look at a reservoir by Price Engineering that takes an entirely different approach to the use of the reservoir. Second, we will look at a Cylindrical Reservoir that was designed for a more efficient removal of contamination from the fluid. Last, we will look at a new concept in reservoirs, designed and patented by Smart Reservoir. We learned in our hydraulics 101 course that there are four primary functions of a reservoir. First, of course, is to store the fluid. Second is to allow enough time for the air to escape. Third is to allow enough time for the particulate matter to settle out. And fourth is to allow a certain amount of cooling to take place.

WWW.FLUIDPOWERJOURNAL.COM | WWW.IFPS.ORG

Studies have shown that it takes approximately two minutes for the air to escape and for the particulate matter to settle out. That is the reason for the rule of thumb that the reservoir capacity should be two to three times the average pump flow. The theory is that the fluid will be able to reside in the reservoir for two to three minutes, allowing it time to give up its air, give up its particulate, and give up its heat. There are some aspects of the traditional, rectangular reservoir that need to be evaluated to see if they really have value. As stated earlier, the fluid is intended to remain in the reservoir for at least two minutes while the particulate settles out. The reality is that, in most rectangular reservoirs, the fluid tends to create its own direct path from the inlet to the outlet. This causes a large percentage of the fluid to simply swirl around inside the reservoir and not be drawn out into the system. Much of the flu-

EREN

id remains in the reservoir, and the working fluid is not refreshed. The swirling action is relatively gentle, and so the fluid has the opportunity to give up its air and its particulate matter. This raises the question about where the particulate settles. It settles onto the bottom of the tank and collects around the baffles and braces. These particles are separated from the fluid stream, but only until there is some disturbance in flow. This could be from jostling, the return flow from a cylinder with a large differential area, or the draining of an accumulator. The disturbance could send a cloud of material into the stream where it can be drawn out into the pump. Ideally, there is a maintenance program that schedules a periodic cleanout of the tank, but that is not usually the case. The reservoir is typically cleaned only when there has been some other catastrophic event that necessitates the draining of the reservoir. Another aspect is heat removal. There are formulas for calculating the heat transfer through the walls of a reservoir, but the fact is that the transfer is usually quite small in relation to the normal requirements of the system. Hydraulic fluid has a relatively high specific heat. It does not like to take on heat, and it does not like to give it up once it gets it. The heat-carrying molecules in the center of the tank are insulated from the outside wall by all the other molecules that are between it and the wall of the tank. Once the heat gets to the outside wall, it still has to pass through the wall, which is usually made of carbon steel, which itself has a relatively high specific heat. Many designers no longer include the cooling capacity of the reservoir in the calculations for sizing a heat exchanger. The reservoir design by Price Engineering uses a concept patented by Vickers in 1999. The idea is that the removal of the particulate can be done with the filtration system in line. The removal of heat can be handled by an external heat exchanger. That leaves only the removal of the air and the storage of the fluid to be the function of the reservoir. The reservoirs that they produce are cylindrical in shape and are amazingly small in relation to the average pump flows. A typical reservoir consists of a cylinder with two chambers, separated by a horizontal plate. The plate has a hole in the center, which provides a passageway from the lower into the upper chamber. The return fluid enters the reservoir tangentially to the cylinder and below the horizontal plate. The exit port to the pump is opposite the inlet and also is tangential to the cylinder. The relatively small reservoir forces the fluid to travel at very high velocity around the internal circumference of the cylinder. The centrifugal force pushes the dense hydraulic fluid against the wall and squeezes the lighter air bubbles toward the center of the rotating

liquid. The small bubbles combine to make bigger bubbles that escape into the upper chamber and out the vent. The high-velocity fluid traveling around the internal circumference of the cylinder produces a positive pressure at the pump supply port. The major advantage of this cylindrical reservoir is that it reduces the size of the reservoir to a fraction of the traditional type. For example, with an average pump flow of 75 lpm, a reservoir of only 5 liters is required. For the equipment

designer, this means that much less real estate is required. It also means that there is much less weight to be carried, less fluid needs to be purchased, and that an oil spill will have a much lower environmental impact. A characteristic of this design is that the pump flow needs to be relatively constant and to be within parameters that allow the proper velocity of fluid into and out of the reservoir. This tends to limit its use to systems with fixed displacement motors or cylinders with relatively small

differential volumes. Systems that use pressurecompensated pumps, load-sensing pumps, accumulators, or high-ratio double-acting cylinders may not be good candidates for this type of reservoir. They are currently available in a variety of sizes for pump flows of up to 380 lpm. There is no claim that these reservoirs are used for the removal of particulate matter or the removal of heat. However, preliminary studies have shown that, because the heated oil is traversing about 1 1/2 times around the inside wall of the reservoir before it is drawn out to the pump, the heat extraction is about 75% of what would be expected by a traditional reservoir. The Cylindrical Reservoir uses some of the same principles as the one designed by Price Engineering. However, this cylindrical reservoir uses relatively low-velocity fluid in the return line to gently rotate the fluid within the cylinder wall. Centrifugal force separates the fluid into layers of density so the air and low-density particles move toward the center and the high-density contaminates move to the wall of the tank. This reservoir has a conical bottom to which is attached the intake to a kidney loop. The system allows the air to escape to the top of the fluid and out through the vent. The particulate settles

CIRCLE 218

WWW.FLUIDPOWERJOURNAL.COM | WWW.IFPS.ORG

down into the cone at the bottom. The cone is attached to the cylinder with a smooth seam, so there is no place for the contamination to collect. The flow through the cone into the kidney loop constantly washes away the particulate, so there is no settling of material at the bottom of the reservoir. Like in the small cylindrical reservoir described earlier, the inlet and outlet are connected tangentially to the cylinder, opposite to each other, and at different levels. This arrangement, along with the normal vortex created by the flow into the kidney loop, causes the warm returning fluid to rotate around the inner wall of the cylinder several times before it exits the reservoir to the pump. Traveling slowly, the warm oil has a much greater chance to give up its heat through the reservoir wall. The heat removal is optimized when the device is made of aluminum, which has a much better capacity to dissipate heat than would carbon steel. There are some important characteristics of this particular design. The reservoir is not being used for an extended dwell time for particulate and air to be removed. This is done dynamically rather than passively and reduces the amount of fluid required. A cylindrical reservoir has a

smaller footprint than a rectangular reservoir of the same volume. Also, a cylindrical shape has greater structural integrity than a rectangular box and therefore can be made out of thinner material. This reservoir is not limited to a consistent return line flow in order to maintain the gentle vortex in the center. The fluid drawn into the kidney loop naturally produces a gentle spinning motion within the reservoir even if there is no return line flow. There is no need for the scheduled cleanout of the reservoir. It may be that the heat exchanger can be reduced in size or eliminated altogether. As in the cylindrical reservoir that uses high velocity, with the Variable Volume Reservoir (VVR), it is assumed that the filtration and heat exchange will occur as a separate part of the circuit. Otherwise, the VVR is quite different. Both of the cylindrical reservoirs are vented to atmosphere. The VVR is a completely closed system. It consists of a bladder that is spring offset in a collapsed state. When it is commissioned, all the air is vented out and then the bladder is sealed. The advantage to this is that the reservoir does not breathe. It does not draw in moisture or dirt, adding to the life of the oil by reducing oxidation. The volume of the reservoir is deter-

mined by the differential volume of the actuators and the thermal expansion that may occur. If the actuators are hydraulic motors, double rod cylinders, or cylinders in series opposing one another as in a steering system, there is no differential volume and the VVR only needs to be sized to accommodate thermal expansion. The size of the reservoir is totally independent of the pump flow. Because it only sees return line flow, it is also totally independent of system pressure. At first it appears that a system using the VVR is very similar to a hydrostatic transmission in

that the return flow is directed to the suction line of the pump. The difference is that there can be multiple pumps supplying multiple actuators. If all the cylinders are extended and the hydraulic fluid is cool, the reservoir is in a spring offset, relaxed state. As the cylinders retract and the temperature increases, the additional fluid in the return line causes the bladder to expand against the spring. This produces a positive pressure in the reservoir between 1 and 9 psi. It is important to note that the reservoir does not see the rush of the return line fluid. It only

sees the differential volume in the return line. Consequently, the fluid in the reservoir is relatively quiescent. Any air in the system rises to the top and is not drawn back into the fluid stream as the bladder contracts and expands. The positive pressure in the reservoir reduces the possibility of cavitation at the pump and allows the pump to be set at a substantially higher elevation than the reservoir. The VVR is currently available in three different sizes: 7 L, 14 L, and 27 L. When choosing a reservoir for an application, approximately 75% of the capacity is reserved for the differential volume of the actuators. The remaining 25% is for potential thermal expansion. If greater volumes are required, multiple reservoirs can be mounted together in series on a manifold.

in Oil and Gas luid sensing in oil and gas is more important than ever. Water, oils, and chemical fluids are integral throughout the life cycle of a well, and even more so with the increased activity in unconventional drilling techniques, such as hydraulic fracturing. New techniques and regulations have added the need to monitor a wide variety of chemicals along with processing flow back and produced wastewater. Liquid level sensing now goes beyond the issues of equipment performance and reliability. Today’s producers must contend with the byproducts of their operations to provide better protection against environmental contamination through better collection, storage, and treatment. Each of these steps is handled more efficiently, and with better assurance, when liquid level sensing is applied.

Produced Water Monitoring with Reliable Level Sensors Although hydraulic fracturing is today exempt from the Clean Water Act, various environmental groups are pressing drilling companies to act in good faith and selfgovern their practices of controlling water use and contaminants.

WITH THE GROWTH IN UNCONVENTIONAL DRILLING, THE NEED FOR LIQUID LEVEL SENSORS GROWS. A long list of toxins is associated with found water resulting from environmental drilling. Depending on the location, size, and duration of the drilling site, treatment of produced water may happen at the site or may be transported to other treatment facilities. Regardless, this contaminated water is typically stored onsite in some fashion until it is treated. Some of the most common chemicals in found water include • Methanol • Isopropanol • Ethylene glycol monobutyl ether (2-butoxyethanol) • Ethylene glycol (1,2-ethanediol) • Hydrotreated light petroleum distillates • Sodium hydroxide (Caustic soda) Successful plans deal with the continuous collection, treatment, and disposal of these and other toxins as part of the overall oil and gas production routine. Use of

reliable liquid level sensing has become a major component of executing these plans. Failures have been costly. Following an EPA action, Exxon recently agreed to pay a $100K penalty and spend an estimated $20M to prevent spills of wastewater from gas-drilling operations in Pennsylvania and West Virginia. At issue was a spill in 2010 where state inspectors came across a leak stemming from an open valve at a frack water recycling plant. Inspectors noted that the open valve was connected to a series of tanks that held wastewater from fracking wells throughout the state. Sensing unexpected drops in fluid level within these tanks could have prevented what was determined to be a release of chlorides, strontium, and barium into a nearby river supplying local drinking water. As part of the agreement, the company must install a continuous, remote monitoring system for all of its permanent production located throughout Pennsylvania and West Virginia with alarms that will be triggered to alert operators immediately in the event of any future spills, and implement a program to actively monitor interconnected wastewater storage tanks. Similarly, and also in Pennsylvania, unnoticed malfunctions released toxic collected fluids from fracking operations. In

one case, 9,000 gallons spilled onto an adjacent farm; in another, the spill was 227,000 gallons that caused the evacuation of many homes. Today, best practices in oil and gas exploration and production provide better assurances to the public about the safety of drinking water and general environmental protection. The Environmental Protection Agency has suggested a solution to continuously monitor the level of wastewater in order to prevent spills of wastewater generated

Accurate Level Detection in Drilling Fluid “Mud” Tanks When drilling, operators need to lubricate the drill bit to avoid excessive temperature by injecting a mixture of compounds called “mud” down into the borehole. There are several tanks that may be used in the process of producing and storing mud, each of which should be monitored for the content level to prevent any cessation of mud delivery to the drill. Examples of mud tanks include the following: • BASE MATERIAL STORAGE TANKS: These tanks hold the base fluids, such as lyes and oils used to produce the mud mixture. They are normally located near or on the drilling platforms. Buoyancy, capacitance, and optical low-level sensors serve this application. • MUD PITS: These tanks normally include nozzles or agitators to keep the mud mixed consistently. The sensing technology used in these tanks must be able to sense a variety of mixtures with a wide range of viscosity and composition. • TRIP TANKS: This is the name given to intermediate storage tanks that hold mud streaming back from the borehole. This mud is contaminated with oil, gas, seawater, rock, and sand, and must be stored until treated. Mud shakers are used to remove rocks and sand to reclaim liquid components of mud. Containment tanks used in the process should include level sensing. A variety of point level switches and continuous level transmitters have been used for decades by a variety of tank manufacturers to detect an adequate level of mud and its constituents before, during, and after its primary use in the borehole. These sensors typically interface with controllers that automate processes

Global Manufacturing Update BY CHAD MOUTRAY, CHIEF ECONOMIST, NATIONAL ASSOCIATION OF MANUFACTURERS (NAM)

March 21, 2014 – Headlines around the world have focused on the Russian annexation of the Crimean peninsula from the Ukraine and the mysterious disappearance of a Malaysian Airlines jetliner. Each of these events injects an element of uncertainty in the global dynamic picture. Indeed, so far in 2014, the global economy has not built on the strong momentum that we saw in the second half of 2013. A number of winter storms in the United States, financial struggles in the emerging markets, and decelerating growth in China have combined to soften growth in recent months. Yet, we should not lose track of the longer-term trend, as markets in many of our largest trading partners have made significant progress over the course of the past year, with modest growth rates overall. The JPMorgan Global Manufacturing Purchasing Managers’ Index (PMI) increased from 53.0 in January to 53.3 in February, its highest point since April 2011. New orders, exports, and hiring rose. That said, this glob-

al measure might also be skewed higher by stronger performance in the United States, with the Markit U.S. Manufacturing PMI jumping from 53.7 to 57.1, its fastest pace in nearly three years. Sales and production both rebounded in February after weather dampened demand and hampered output and shipments in January. Elsewhere, there were signs that manufacturing activity eased somewhat in February in a number of areas, with a definite split between the developed nations and emerging markets. The

HSBC Emerging Markets Index dropped from 51.4 to 51.1, influenced by contracting levels of activity in China, Russia, and South Korea. Speaking of China, its manufacturing PMI has now contracted for two straight months, and a number of economic indicators suggest that its economy has continued to decelerate. Industrial production has slowed from 10.4% in August to 8.6% in February, and fixed asset investment and retail sales have also eased

significantly. These data points suggest that real GDP might fall below the 7.7% rate seen in the fourth quarter. Still, growth remains strong overall, even if these figures are well below the rates of growth that many businesses have become accustomed to. In other news, the Bank of China has worked to weaken its currency over the past month, with the Chinese yuan depreciating more than 2% since mid-February. The Chinese government has

engineered this devaluation, it says, to help fend off speculators; yet, it is also important to note that the yuan has generally appreciated against the U.S. dollar since 2005. (See the graphic on the previous page.) Looking at our largest trading partners, 8 of the top 10 markets for U.S.-manufactured goods had expanding levels of manufacturing activity, with five countries experiencing slightly faster growth in February than in January. For example, the Canadian economy grew marginally faster in the fourth quarter, with real GDP up 2.9% in the fourth quarter. Manufacturing capacity utilization and shipments have also picked up recently, and the RBC Canadian Manufacturing PMI increased from 51.7 to 52.9, suggest modest growth. Meanwhile, in Europe, sentiment dipped somewhat in February, but the trend since last summer remains positive. New orders, exports, and production eased a little for the month, but growth still remained healthy overall. Real GDP increased 0.3% in the fourth quarter, but growth is expected to rise to 1.1% for 2014 as a whole. While that indicates very slow growth, it is enough to provide a psychological boost to many businesses and consumers. The one issue that we do continue to worry about is possible disinflation, with still-weak demand keeping price growth at a minimum. Consumer prices have risen just 0.7% over the past year, for instance. On the policy front, the Senate Finance Committee boasts a new chairman, as trade legislation from Trade Promotion Authority (TPA) to the Miscellaneous Tariff Bill (MTB) awaits action. Globally, Russia’s activities in Crimea and the Ukraine are prompting action by the Obama Administration and Congress, while trade talks in the Asia-Pacific and with Europe continue. Work has started on a bill to reauthorize the Export-Import (Ex-Im) Bank before the end of September.

FLUID POWER CASE STUDY

Moog high-flow servo valves with highperformance pilot servo valves like the one pictured in this motion base are used in the Exova Defiance custom repair program.

CUSTOM REPAIR PROGRAM FOR SERVO VALVES KEEPS TEST RIGS RUNNING By STEVE BEDDICK, MOOG INDUSTRIAL GROUP

WWW.FLUIDPOWERJOURNAL.COM | WWW.IFPS.ORG

roving grounds aren’t always the most effective way to test the durability of a truck or car. If a car maker wants to evaluate, for example, a light truck frame or suspension, then testing groups often get a call to simulate any number of road conditions. The results from strength, compression, and vibration tests help car makers build a better product. Michiganbased Exova is an example of a testing group that conducts simulations using equipment such as an 18-channel, full-vehicle inertial road simulator. “We can complete some tests in a day; others take more time,” says Jeff Taylor, supervisor of the Exova Defiance Technical Services Group. “A testing program for a frame maker can last more than a year.” Test groups like Taylor’s employer test the prototype frame, and then the frame maker will run a few samples off the production line, which they also assess. To make these simulators run, each test rig relies on the operation of highperformance servo valves. Exova Defiance runs everything from single-channel tests, which require one servo valve, to large custom test rigs with 20 or more channels, which employ 30 or more valves.

WHAT IS YOUR TEST RIG RIDING ON? A well-made servo valve is a dependable piece of technology. That’s important because—no pun intended—test groups and car makers have a lot riding on them. Until a few years ago, the most important thing about the nearly 600 servo valves Exova Defiance owns (other than keeping them running) was finding the closest, least expensive, and most dependable repair shop to fix the valves when they failed. The servo valve controls how hydraulic fluid is channeled to an actuator, which will simulate a variety of stress factors. When it comes to performing fatigue testing, servo valves that employ mechanical feedback are generally thought of as having the fastest response time, enabling a test house to cycle a specimen to a point of fatigue in the shortest time. When a test house puts stress on a vehicle system or component, says Taylor, it needs “highresponse servo valves to get the desired results.” If there are excessive particulates or dirt in the fluid running through the servo valve, it will affect the performance of, and accelerate the wear on, the servo valve. Servo valves will fail if operators are not maintaining the proper level of cleanliness in the fluid. If a test rig begins behav-

ing erratically, it’s often a telltale sign that the servo valve requires maintenance. “Our largest reliability issue with servo valves was ‘ball glitch,’” added Taylor. This occurs when a valve operates in even a mildly contaminated environment for hundreds of thousands of cycles. When a test house runs a flow plot on one of its test stands, operators can easily identify this issue by plotting the output of current versus flow.

CONSIDERING THE QUALITY OF REPAIR In the greater Detroit area, there are at least a dozen local hydraulic repair facilities that advertise servo valve repair capability. Exova Defiance would send its valves to these companies due to their quick turnaround times, competitive prices, and no shipping costs. In 2009, Moog (the company that makes most of the servo valves used by Exova Defiance) asked Taylor to consider Moog for servo valve repairs. While controlling servo valve repair costs is important, test houses also consider the repercussions of a failed test. For instance, the worstcase scenario would be a catastrophic failure that would cause a cylinder to cycle full stroke (or force) and damage a customer test specimen and invalidate a test. Many projects have a very limited quantity or even one-of-a-kind test samples. More often, servo valves simply exhibit erratic behavior (e.g., instability, glitches, etc.). When an operator swaps valves during a test, he or she will always be focused on whether or not the new valve is performing exactly the same as the old one prior to the problem. When evaluating a servo valve repair partner, take into account how a manufacturer supports independent repair shops, the quality of repairs being made, and the availability of upgrades. Some servo valve manufacturers sell parts and offer support to independent repair companies. Other manufacturers might centralize repairs at a single authorized service facility; these manufacturers do not sell repair parts or publish test specifications. And they would be the only source for an OEM-quality repair. It’s also worth asking if your servo valve repair partner will include a free upgrade to its latest technology product.

switch from our local repair house to working with our manufacturer,” said Taylor. What Taylor was able to get with the customized repair program was a local inventory, a fixed price for repairs, and a like-new repair job or upgrade. Moog warrants the entire valve for two years, even when it only performs a cleanand-calibrate service. It’s like purchasing a brand-new valve. After three years, we’ve signed a two-year renewal contract. “The customized repair program keeps our test rigs running smoothly, improves the quality of our servo valves, and comes at a price we can afford,” remarked Taylor.

A CUSTOMIZED APPROACH “Moog told us that regardless of our circumstance and priorities, it would customize a repair program to help us,” said Taylor. “Moog arranged to maintain a stock of its servo valves in Plymouth, Mich., near our test laboratories.” By repairing the servo valve and, when appropriate, upgrading the servo valve to the latest model revision using a carbide feedback ball, a longer-lasting design that Moog invented, Exova Defiance always has a ready supply of servo valves. To simplify the repair administration process, Moog offered a fixed price based on a blended rate of its three standard repair levels; this also eliminates the need for quotes or purchase order revisions. “This local, customized support combined with the carbide ball upgrade caused us to

IFPE AND CONEXPO-CON/AGG 2014

ATTRACT NEARLY 130,000 – NEW EXHIBIT AND EDUCATION RECORDS THE FUTURE ON DISPLAY AS GLOBAL INDUSTRY SHOWCASE SPOTLIGHTS NEW PRODUCT INNOVATIONS, TECHNOLOGY IFPE and CONEXPO-CON/AGG 2014 took center stage in Las Vegas, Nev., March 4-8 with tremendous energy and serious buyers. Total registration of 129,364 soared past the last edition of the shows as they achieved the second-highest attendance in their history. The shows also set new records for exhibit space, number of exhibitors, and education tickets sold. The co-located IFPE and CONEXPO-CON/AGG, at the Las Vegas Convention Center, delivered a global showcase of the newest product innovations and technologies for the construction, construction materials, and fluid power/power transmission/motion control industries with more than 1,000 new products and services on display.

WWW.FLUIDPOWERJOURNAL.COM | WWW.IFPS.ORG

Attendees also took advantage of the shows’ strong industry education programs and the unparalleled opportunity to connect with industry peers, take the pulse of what’s happening, and learn what the future holds. “The enthusiasm and traffic on the show floor was just incredible. Exhibitors cited the high quality of attendees; they told us these were serious buyers and reported robust sales to existing as well as new customers that exceeded their expectations,” stated Megan Tanel, CONEXPO-CON/ AGG show director.

QUALITY ATTENDANCE, INTERNATIONAL SCOPE IFPE and CONEXPO-CON/AGG 2014 maintained the growing international scope of the shows with international registrations totaling more than 31,000—an increase of 9% from the most recent events. The number of countries represented increased to 170 from 159 in 2011, and the number of international attendees matched the record 24% of total attendance

set in 2011. International attendance drew heavily from Latin America, China, Canada, and Europe. More than 75% of show visitors were in managerial roles (with 36% of these with the top titles of president/owner and vice president/general manager/chief financial officer). Both shows set new records for exhibit space and number of exhibitors: CONEXPO-CON/AGG with more than 2.35 million net square feet of exhibit space and more than 2,000 exhibitors, and IFPE with more than 161,000 net square feet and 400 exhibitors. A record 41,000 education ticket sales were sold to the shows’ education programs, underscoring their relevance to helping attendees succeed in today’s business environment. “CON-EXPO-CON/AGG and IFPE 2014 reflected the feeling of momentum building in the industry. We are industry-run shows with industry needs put first; these show numbers are a testament to the value attendees, exhibitors, and other stakeholders derive from their participation,” said Melissa Magestro, IFPE show director.

GLOBAL INDUSTRY GATHERING PLACE Among the show visitors were Acting U.S. Deputy Secretary of Commerce Patrick D. Gallagher, Acting U.S. Deputy Secretary of Transportation Victor Mendez, and former U.S. Rep. James Oberstar, who served as chairman of the House Transportation and Infrastructure Committee from 2007 to 2011. The shows were chosen for the prestigious U.S. Department of Commerce (DOC) International Buyers Program, which helps facilitate global attendance. More than 50 official international attendee delegations were organized by DOC, as well as show industry partners. More than 95 allied associations and groups were official supporting organizations, coming from U.S., Canada, and 16 other countries worldwide. Several national industry associations held their annual conventions or high-level board meetings at the shows; they joined hundreds of other industry and company meetings, from large events to smaller committees and other groups, all taking advantage of the shows to meet and share knowledge and learn from one another.

EDUCATION AND EXHIBITS The CONEXPO-CON/AGG 2014 education program covered 120 sessions over 10 targeted tracks. The IFPE Technical Conference anchored IFPE 2014 education, joined by half-day “college-level courses and a new Fluid Power Seminar series.
