The Truth About Compressed Air! If you think compressed air is too expensive and noisy - read this. The facts will surprise you!
Compare these Blowoffs
Facts about Blowers
There are a variety of ways to blow the water from the bottles shown in the photo below, but which method is best? To decide, we ran a comparison test on the same application using four different blowoff methods: drilled pipe, flat air nozzles, Super Air Knife (each using compressed air as a power source), and a blower supplied air knife (using an electric motor as a power source). Each system consisted of two twelve inch long air knives. The following comparison proves that the EXAIR Super Air Knife is the best choice for your blowoff, cooling or drying application.
Energy conscious plants might think a blower to be a better choice due to its slightly lower electrical consumption compared to a compressor. In reality, a blower is an expensive capital expenditure that requires frequent downtime and costly maintenance of filters, belts and bearings.
The goal for each of the blowoff choices was to use the least amount of air possible to get the job done (lowest energy and noise level). The compressed air pressure required was 60 PSIG which provided adequate velocity to blow the water off. The blower used had a ten horsepower motor and was a centrifugal type blower at 18,000 RPM. The table at the bottom of the page summarizes the overall performance. Since your actual part may have an odd configuration, holes or sharp edges, we took sound level measurements in free air (no impinging surface).
Here are some important facts:
Filters must be replaced every one to three months. Belts must be replaced every three to six months. Typical bearing replacement is at least once a year at a cost near $1000.
Blower Air Knife
This common blowoff is very inexpensive and easy to make. For this test, we used (2) drilled pipes, each with (25) 1/16" diameter holes on 1/2" centers. As shown in the test results below, the drilled pipe performed poorly. The initial cost of the drilled pipe is overshadowed by its high energy use. The holes are easily blocked and the noise level is excessive - both of which violate OSHA requirements. Velocity across the entire length was very inconsistent with spikes of air and numerous dead spots.
The blower proved to be an expensive, noisy option. As noted below, the purchase price is high. Operating cost was considerably lower than the drilled pipe and flat air nozzle, but was comparable to EXAIR’s Super Air Knife. The large blower with its two 3" (8cm) diameter hoses requires significant mounting space compared to the others. Noise level was high at 90 dBA. There was no option for cycling it on and off to conserve energy like the other blowoffs. Costly bearing and filter maintenance along with downtime were also negative factors.
Flat Air Nozzles
EXAIR Super Air Knife
As shown below, this inexpensive air nozzle was the worst performer. It is available in plastic, aluminum and stainless steel from several manufacturers. The flat air nozzle provides some entrainment, but suffers from many of the same problems as the drilled pipe. Operating cost and noise level are both high. Some manufacturers offer flat air nozzles where the holes can be blocked - an OSHA violation. Velocity was inconsistent with spikes of air.
The Super Air Knife did an exceptional job of removing the moisture on one pass due to the uniformity of the laminar airflow. The sound level was extremely low. For this application, energy use was slightly higher than the blower but can be less than the blower if cycling on and off is possible. Safe operation is not an issue since the Super Air Knife can not be deadended. Maintenance costs are low since there are no moving parts to wear out.
Blower bearings wear out quickly due to the high speeds (17-20,000 RPM) required to generate effective airflows. Poorly designed seals that allow dirt and moisture infiltration and environments above 125°F decrease the one year bearing life. Many bearings can not be replaced in the field, resulting in downtime to send the assembly back to the manufacturer.
Blowers take up a lot of space and often produce sound levels that exceed OSHA noise level exposure requirements. Air volume and velocity are often difficult to control since mechanical adjustments are required. To discuss an application, contact:

Shop Goes to College Rick Carter Executive Editor
att Crawford’s excellent 2009 book Shop Class as Soulcraft offers an impassioned case for a return to the values once represented by public-school shop class. I read it recently thanks to my wife, who noticed it in the library of the high school where she teaches—a school, like many others in the U.S., that closed its first-rate shop program. The book relates how Crawford’s circuitous career (he went from electrician to writer to motorcycle mechanic) taught him the value of hands-on work, and why it all began with shop. His opening snapshot of the afterlife of the lathes, table saws and other equipment that was discarded “when shop class started to become a thing of the past,” then offloaded to secondhand markets across the country, is a sobering symbol of a larger loss for America’s youth. Shop was not a universal career-starter, of course, but it brought value by introducing a non-college option, something most of today’s public-school students, and many industrial workers, have missed. The good news today is that this void has not been ignored: The nation’s two-year community colleges are helping to fill it by re-imagining shop’s original mission as career training, shaped by and for manufacturers.
The nation’s community colleges have re-imagined shop’s original mission as career training, shaped by and for manufacturers. Educator and former MARTS presenter Mark Combs has been a part of this effort since 2008, working with manufacturers and faculty to create courses and schedules that accommodate the needs of both workers and community-college students interested in industrial careers. It began for Combs when he was Program Manager for Business Training at Parkland College, a two-year school in
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
Champaign, IL. The nearby Kraft Foods operation asked if the school could train the plant’s workers to become maintenance technicians. The request led to a partnership with Kraft that exists to this day. At the time, Parkland’s Industrial Technology program lacked the resources to meet Kraft’s needs, so Combs enlisted other local manufacturers with similar needs to join a training partnership. He then applied for and received a grant from the U.S. Department of Labor. “This allowed the college to get new equipment and hire people to help train both incumbent workers and college students,” says Combs. The manufacturers also donated equipment, manufacturing expertise, served on curriculum advisory boards and covered half of their employees’ tuition. The other half was covered by the local workforce-investment agency. Parkland’s courses filled quickly: 35 incumbent workers at first, says Combs, along with 45 full- and part-time college students, “most of whom were unaware that manufacturing employment paid so well and actually had career opportunities.” Not everyone completed the program, but those who did went on to well-paying positions with Kraft or the other partners. Though the original grant ended in 2012, it was designed so enrolled workers could continue training afterward. The last who signed on under the original funding will finish in 2015. Combs, who now teaches part-time at Parkland, says the school has become an established training source for local manufacturers. “We have an Industrial Maintenance Technology Certificate for technicians that did not exist before, and over $750,000 of equipment purchased with grant money that is used in classes to help train maintenance technicians.” Those classes are offered on a regular basis, he says, and people are enrolling in them. A similar situation may be underway at a community college near you. According to Combs, you’ll probably find the classes and programs there that can help train your workers. If not, he says, most faculty and department chairs are eager to hear what’s needed. These schools are aware of the skilled-labor shortage, and want to help address it. All you may have to do is ask.

Hourly Compensation Systems: Does Yours De-motivate? Bob Williamson Contributing Editor
oney motivates us—or does it? When we receive higher pay, does it compel us to improve our performance, be more productive or become more loyal? Not necessarily. The perception that our pay is sub-par, however, can be a serious de-motivating factor that affects both performance and productivity. In the workplace, employees are subject to a wide variety of job classification systems and pay grades that guide the amount of monetary compensation they receive. While some pay rates are negotiated through collective bargaining or are the product of compensation studies, most are based on business needs, comparable job roles, responsibilities and rates in the region. In an era of growing skills shortages, we need to ask: “Is our hourly compensation system a de-motivator? Does it discourage current employees and chase away the best and brightest we need to attract?” Let’s explore the typical hourly compensation of maintenance employees to see how pay can de-motivate, and what can be done to change this dynamic. Consider the following real-world example from my own archives:
When employees perceive that their pay is sub-par, their performance and productivity can be negatively affected. Happy and not-so-happy campers The XYZ Manufacturing Co. (not its real name) was a preferred employer in the area. A well-established operation, it was staffed with a highly experienced 165-person maintenance workforce for everything from facility and utilities to assembly and production processes. XYZ had two primary maintenance
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
job classifications: Mechanical Maintenance and Electrical Maintenance. Maintenance workers were slotted into one of these classifications from the start of their seniority in the maintenance department. Electrical Maintenance work included power distribution, machinery electrical systems and instrumentation/controls. Mechanical Maintenance work included welding and fabrication, machining, lubrication/oilers, fork trucks and machine repair. Each job classification had the same four negotiated pay grades and hourly rates. The lowest pay was for new hires and trainees, the highest was for the most senior maintenance employees. Progression from entry-level to top pay was basically automatic unless penalizing behaviors or habits occurred, which was rare. After 15 years, all 165 maintenance employees were at the top pay grade and receiving top hourly pay, including those who hired on within the previous five years. While the most senior maintenance employees received top pay, those with lower seniority quickly caught up with them. This made XYZ’s compensation system easy to manage. Annual across-the-board raises and contract negotiations were relatively straightforward. But the monetary increases affected all maintenance employees exactly the same way because all were at top pay. The not-so-happy-campers were those employees who performed highly skilled instrumentation/ controls and machine-repair work. They were stuck at the top pay grade along with those in markedly lower skill-level roles. Electricians, lubrication/oilers and fork truck mechanics, for example, were paid the same as machine repairmen and instrumentation/ controls technicians. The electricians, oilers and mechanics felt that pay was NOT an issue: They could focus on their work. However, the machine repairmen and instrument/controls technicians—whose jobs required continual skills and knowledge upgrades every time new automated machinery was installed in the plant—were highly de-motivated by their pay and disgruntled about their workloads.
Breaking the camel’s back De-motivation among the top-skilled machinerepair and instrumentation technicians came to a head when XYZ’s primary processes were upgraded in a major engineering project. “Why should we master new technologies again and again,” they asked, “while our fellow maintenance workers get the same pay we do and don’t have to continually learn new technologies?” Further complicating matters, XYZ was unable to find new, highly skilled machine-repair and instrumentation/controls technicians, despite the fact that new hires would start at the top pay grade. The company was unable to attract the best and brightest it needed to maintain, calibrate, troubleshoot and repair the new automated manufacturing technologies. In a practical sense, something had to be done to recognize that certain maintenance jobs required higher, frequently changing skills and knowledge. Stalemate. The skills shortage was the real eye-opener for both the personnel department and the maintenance employees. Though XYZ’s top-performing maintenance employees ranked as senior personnel, they started to look for work elsewhere. Their skills, knowledge and experience were increasingly in demand.
Pay-for-applied-skills to the rescue It was necessary to find a way to “stratify” the maintenance job-performance skills sets required at XYZ. This had to be done in a way that would provide advancement opportunities for all who were interested without penalizing anyone. A new, opt-in training and advancement program was created, which proceeded as follows: A detailed duty-task analysis was performed to identify job-performance requirements (skills and knowledge) for current as well as higher-level skilled job roles (machine repair and instrumentation/controls). Three new pay grades topping out at more than a $2.00-per-hour increment were identified with specific requirements for advancement. The new pay grades reflected opportunities for crossover skills where instrument/controls personnel would acquire certain critical mechanical skills, and machine-repair personnel would acquire certain critical electrical/electronic skills for a “multi-skill maintenance” approach.
Aptitude and ability “assessments” (not “tests”) were required to begin training, and for all higherlevel job classifications. Assessments included mechanical aptitude, learning ability and computer literacy, plus reading, writing and basic math. Individual scores were to be reported only to the person being assessed and the training manager. The existing skills and knowledge of those entering the training program were identified. Maintenance employees wishing to train for higher-level jobs then reviewed the detailed duty-task analysis of the higher-level skills and knowledge as a “selfassessment.”
Companies can’t afford to let their compensation systems keep them from attracting the best and the brightest workers. Also, several highly skilled machine-repair and instrument/controls and employees were selected and trained to be instructor/trainers. Their first assignment was to construct training devices with actual plant equipment that would duplicate the critical new-technology machines and controls and some essential prerequisite skills. Following their “self-assessments,” employees were asked to demonstrate their abilities to perform the identified duties and tasks on actual plant equipment or on the training devices. This performance demonstration was observed and monitored by the job-specific instructors/trainers, a supervisor and another hourly maintenance person. Training began on critical skills for improving existing manufacturing processes, as well as those needed for emerging technologies. A variety of approaches were used, from self-study to classroom and vendor/OEM to on-job coaching. All training conformed to the duty-task analysis. Written testing was not used to verify job skills and knowledge. The same hands-on performance demonstration process—according to the duty-task lists—was used after training to assure proper job performance.

The skills shortage opened eyes. The company’s high-performing maintenance employees started to look for work elsewhere because their skills, knowledge and experience were in demand. Pay no longer a de-motivator The new job classifications, training and compensation at the XYZ Manufacturing Co. reflected the top priority needs of the plant. Pay was no longer a de-motivator for top-skilled maintenance employees. Maintenance-job roles and performance requirements were stratified. While everyone had the opportunity to participate at the higher skill levels, many opted for improving their skills and knowledge with regard to their current job roles. Those who had reading,
writing or math deficiencies for their job roles received individual tutoring and participated in skills-improvement programs. Within a few months of completing the first wave of training and qualification, a major, chronic problem area in the plant stopped having problems. Machine performance improved and breakdowns rarely occurred. Engaged with their new work, XYZ’s former not-so-happy campers were celebrating—along with the labor union and plant management.
As aging Baby Boomers exit the workforce and younger workers try to fill their shoes, it may be time to rethink your own hourly maintenance compensation system. MT&AP

Minute Maintenance, Part 2 Ken Bannister Contributing Editor
et’s recap from Part 1 (pgs. 12-13, MT&AP, Jan. 2014): Minute Maintenance is the pursuit and implementation of innovative proactive maintenance methods, processes, techniques and tools designed to reduce or eliminate non-value-added (waste) maintenance activity to produce an efficient, effective maintenance result measured in minutes, using a lesser skill-set requirement than that needed to perform a repair. Major interventions (i.e., overhauls and repairs) require time and high skill levels, and almost always result in major asset dependability (reliability, availability and maintainability) and production-downtime losses. Minimizing loss (waste) is achieved by understanding and identifying failure onset in a timely manner through the recognition of an asset’s current condition compared to its optimum condition so that only minor intervention is required to assure asset dependability with little or no downtime loss. As an asset progresses through its life cycle, it can be subjected to many external influences that can cause and/or accelerate component failures. These influences include temperature (heat, cold), vibration, contamination (water, dirt), neglect and abuse—all of which conspire to produce premature wear and a corresponding requirement for major maintenance. Recognizing and managing these influences can significantly increase an asset’s reliability and service life.
Recognizing and managing external influences can significantly increase an asset’s service life. Machine designers are aware they have little control over the external influences or “ambient condition factors” to which their equipment will be subjected. To compensate, they design equipment with consumable devices intended to act as part
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
of the machine system and, more importantly, as a “tell-tale fusible link” to protect major components and systems. We know these “devices” as lubricants, filters, belts, couplings, fuses, adjustment/ calibration mechanisms, and others. Intended as the “weakest link” in the design, they’re simple to assess and correct and, as such, must figure in our proactive minute-maintenance approach. In turn, we can build a simple and effective preventive maintenancecheck program around the referenced consumable devices and external influences. Consider the following V-belt example.
A motorized, belt-driven fan unit V-belt drive systems transmit power at a defined number of revolutions per minute (RPM) from a motor-driven “drive” sheave pulley to one or more “driven” sheave pulleys attached to, in this case, a fan shaft. A V-belt is designed to “wedge” itself into the v-shaped sheave groove and ride with full belt-side contact at the top of the groove, leaving a substantial gap between the bottom of the belt and the groove valley. Worn or non-matched belts that ride lower in the groove (known as differential driving) can eventually bottom out and polish the groove valley and should be replaced quickly. To transmit power efficiently, one of the sheaves employs an adjuster mechanism to allow the belt(s) to be tensioned to a point that under load will “slip” between 1% to 3% and permit intentional creep and release from the wedged position in the groove as the pulley turns. If tension is below 1% (too tight), the belt won’t release correctly and, consequently, generate frictional heat; if over 3% (too loose), the belt will slip too much and start to “dance,” creating rubbing friction in the sheave, raising the temperature and causing premature wear of both belt and sheave. Checking for slip is simply a matter of using a handheld strobe light to check and calculate the RPM speed difference between the driver and driven pulley. For example, if a 1750-RPM motor is used with 1:1 ratio sheaves, the driven pulley should be running between 1700 and 1730 RPM when tensioned correctly. If not, it’s in a no-go state
requiring immediate attention. A correctly tensioned belt running on an unworn, correctly aligned sheave pulley is designed to return an operational efficiency close to 97%. Most V-belts are manufactured from an elastomer that encases longitudinal rows of polyester or Kevlar internal-tension members. During power transfer, belts are subjected to fatigue-causing stresses that eventually lead the belt-tension members to fail. But, provided the belts operate at a temperature less than 120 F and are installed correctly, they can be expected to deliver 15,000 hours or more of belt-life. High operating loads with large fans and motors require multiple belts to transmit power with minimum energy losses. These belts must be matched if they are to be tensioned successfully. Matched belts are often purchased in sets of two, four, six, etc., that are manufactured from the same batch of rubber. If a system is designed for six belts and only five are used, it will be under a high operating load and surpass the belt-load design factor—leading to overheating, inefficiency and premature failure. Belts should be visually inspected regularly to ensure all are in place and that they are matched. Misalignment, in both offset and angular form, is a major problem with belt-driven systems. It causes a belt’s tension members to flex sideward and vibrate, creating additional stress. When a misaligned belt enters into the sheave groove, it “rubs” the sheave wall, raising the belt temperature through frictional heat that results in rapid wear of both belt and sheave. Precision alignment of driver/driven systems using laser or reverse-dial methods is a must to reduce heat, wear and energy loss. Sheave wear is easily checked using a $10 sheave profile gage. The “tooth” profile is placed in the sheave groove and a flashlight is shone from behind. If more than 1/32” of light (wear) is evident, a no-go state exists, requiring replacement of the sheaves and belts. Once the motor and fan are aligned and all fasteners torqued correctly, the driven system will run quietly with virtually no vibration present in the motor. When this is achieved, the motor fastener bolts and frame tension adjuster nuts can be line-painted in position, with a check line across the fastener onto the fastener plate. If the fastener becomes loose and slackens off, the painted lines will not align. This will indicate a no-go state and quickly allow the problem to be noticed and arrested.
Taking this approach and building a first-alert PM based on the equipment’s weakest link helps us compile a checklist like the one shown below, that will identify, in minutes, a no-go state (exception-based maintenance) requiring a skilled intervention.
Minute Maintenance: Belt-Drive Assembly Checklist Check the check box against the task only when a no-go exception is found. Using a strobe light, check that driven pulley speed is between 1700 and 1730 RPM. Using an IR thermometer or camera, check that each belt temperature is < 120 F. Check that all motor painted fastener alignment check lines are aligned. Check that there are no dancing or heavily vibrating belt(s). Check that all belts are matched for size and batch numbered. Check that all belts sit in a similar position, flush with the outside sheave diameter. Check for smell of burning rubber. Check for visible signs of abraded rubber around the sheave pulley. When machine is not running, open machineguard inspection window and check all sheave grooves using a groove-profile gage and flashlight for <1/32” wear (LOCKOUT required). Performed on equipment that is running (with exception of the last task), this simple-objective checklist can be completed in less than 10 minutes, by a minimally trained non- or semi-skilled individual. Any no-go finding is to be immediately acted upon by skilled personnel. Good luck! MT&AP email@example.com

Survey Finds Growing Awareness of Counterfeit Electrical Parts Research by Eaton and IEC Validates Importance of Educational Campaigns Power management company Eaton and the Independent Electrical Contractors (IEC) association have released findings of a joint survey that validate the effectiveness of educational programs about the dangers of counterfeit electrical products. The Eaton/IEC research found that IEC members understand the potential safety dangers of counterfeit products, the sophistication of counterfeiters and how to avoid counterfeit products by purchasing directly from the manufacturer’s authorized distributors or resellers. Survey responses, however, also revealed the
need for more best-practice sharing and methods to thwart counterfeiting. “Electrical contractors recognize the prevalence and dangers of counterfeits,” said Tom Grace, Brand Protection Manager, Eaton’s Electrical Sector Americas. “Now we need to up our game and provide contractors with easier ways to report counterfeit products and build collaboration among manufacturers, industry organizations and government.” The complete results of the Eaton/ IEC survey are available at eaton.com/ counterfeit.

Is It Just Reliability?
Our Hands-On Electrical Maintenance Training Not Only Increases Production, It Keeps Your Technicians Safe.
By Richard E. Wood, AVO Training Institute, Senior Consultant For more than a decade reliability has become the buzzword in maintenance and engineering. It refers to a program, that when effectively put into action, reduces downtime and increases production. This is accomplished through Preventative Maintenance (PM), Predictive Maintenance (PdM), and Failure Mode & Effects Analysis (FMEA). Although these programs can be very effective when properly administered, there is another area that should not be overlooked. The resource that is often ignored is the training of maintenance technicians and engineers. Many times, this asset is ignored by rationalizing that it is too expensive and that time is lost while employees are attending training sessions. Like any upgrade in a process there is an initial cost. The question is does the initial cost result in increased production and revenue? Manufacturers have realized an increase in production that is directly related to effective training. A good training program enables the technician to quickly identify the failure and return the equipment to the process. Conservatively, production times can easily exceed an increase of ten percent with quality training. Do the math and it quickly becomes apparent that training costs are a small investment when compared to continual production increases. These increases are realized not once, but every day of every year. That is the kind of edge that keeps corporations competitive and increases the profit margin. Costs can also be managed more effectively; for example, a reduction in workforce can also be realized through training. Increased MARCH 2014
work being accomplished in a shorter time can be achieved with a smaller maintenance group. You may ask, “Where does safety come into the picture? How does reliability and training contribute to safety of the maintenance and production personnel?”. A safe environment can be accomplished through the combined effects of reliability and training. Reliability allows for scheduled downtime and planned maintenance, resulting in fewer breakdowns and rushed repairs. Training prepares the technician with the knowledge to troubleshoot and repair the equipment safely, quickly and effectively. Safety plays an important role when unplanned downtime occurs. When equipment is down the temptation to hurry and take shortcuts is overwhelming. A maintenance technician or production operator can be seriously injured because of the increased pressure to get the equipment back online. Accidents can be a large part of lost production, but most importantly a lifechanging event for someone and his or her family. The safety of all employees has been, and should always be, the first priority. Training employees with the necessary skills to work safely will always equate to a substantial return on the investment.

For Top Performance,
Know Your Critical Equipment
Real-world benefits go well beyond easier decision-making. Jane Alexander Deputy Editor
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
Foreward It’s not possible or necessary for all equipment in a plant to receive equal attention. The key is to focus on the most critical assets—whatever that means to an operation. Applying the principles of asset criticality can facilitate your decision-making and generate a number of other valuable benefits in the process. Your site’s critical-equipment determinations should be based on business goals and objectives, says manufacturing consultant and MT&AP Contributing Editor Bob Williamson. Identify your most critical assets and rank them on a scale based on risk (probability and consequences) or other impact they might have on business goals and values. In this process, you’ll also identify your least critical assets and those somewhere in the middle. “Focused improvement on the most critical few that you ultimately move into a ‘maintenance fast lane’ will lead to enhanced performance,” says Williamson, “and possibly free up reactive maintenance resources to perform more planned/preventive maintenance work.” Modern asset-management methods call for proper attention to be paid to equipment systems throughout their
life cycles: from design and procurement through installation, commissioning, operation and maintenance to renewal and/or decommissioning. This is not something a site can just add to its wish list and forget: The new International Asset Management Standard (ISO-55000, issued in January 2014) requires asset risks to be identified and appropriate risk-management practices put in place. It’s important to remember that “critical equipment” not only includes production-related processes, utilities, facilities equipment and the automated systems that run them, but also health, safety and environmental-related equipment. Often, your most critical assets may also be the most at risk if they fail to perform reliably. The following story by PotashCorp’s Matthew Fenwick makes a good case for how establishment of sound criticality determinations can set the stage for a variety of payoffs. In this first-person account, Fenwick discusses improvements in alert-monitoring-device strategies that, among other things, allow his team to save time and better manage an increasing workload.

DEFINING CRITICAL EQUIPMENT
With improved maintenance, PotashCorp NB is prepared for growth.
Matthew Fenwick, instrumentation technician with PotashCorp in New Brunswick, tells the following story about how they dug deeply to improve efficiency. Our nine-person instrumentation team at PotashCorp’s New Brunswick (NB) division had responsibility for managing 2000 input/output (I/O) points in 2012. Knowing a 4400 I/O point expansion would come online in 2013, we had to find ways to save time and manage the workload. We needed to prioritize the right devices and alerts, reduce time spent on troubleshooting and increase technician efficiency.
Identifying the right devices We first tackled the Alert Monitor function in our asset-management system, Emerson’s AMS Device Manager. With hundreds of alerts coming in, we needed to know which ones were most important for our business. We started by rating plant areas based on criteria such as safety considerations, regulatory compliance, product quality, process throughput and operational cost. Next, we prioritized the loops and devices according to how critical the asset is and how often it fails. The resulting maintenance priority index gave us insight into which areas to target for process changes and which alerts should be configured and channeled to the maintenance-planning department. We’ve established a weekly checkpoint to monitor and process these alerts as part of a proactive maintenance approach. At a glance, technicians can view the Alert Monitor on any engineering station in our plant. They can identify the potential bad actors, do further investigation and make modifications to correct the deficiencies before they become failures.
Reducing troubleshooting The next step was to dig deeper into the way we applied the principles of asset
criticality to our daily work. Specifically, we needed to improve our valve signature management, which was historically our biggest and most expensive area of failure. Emerson’s AMS ValveLink performance My wake-up call was a 3:00 a.m. emerdiagnostic sweep. This gives us a snapshot gency for an issue with a major control of the integrity of the valve components valve, resulting in the loss of six hours using five online tests: Supply Pressure of prime production.

and device checks during start-ups. After I spent time exploring the tool in depth, I saw the potential to use it as a way to instantly bring information to technicians. We created an embedded program in the AMS Device Manager—using a Microsoft Access Database run by Visual Basic—to provide access to all our maintenance documentation with the click of a mouse (no more searching in the maintenance shop or control room for the book with loop configuration diagrams). Similar to a personalized search engine, we have all needed documentation in an organized, easy-to-find format that we call the Instrumentation Information Web. In 2012, we captured the impact of the Instrumentation Information Web through a pilot project. Our instrumentation planner estimated the team would spend 807 hours working on proactive maintenance tasks based on work orders. However, with the implementation of the Instrumentation Information Web, the department spent only 376 hours on proactive tasks, a savings of more than 50% over the course of the pilot. We have also seen substantial savings in commissioning and alerts. We devised a manual for alarm configuration and installed it on a Wireless Mobile Worker application. This has saved thousands of hours in commissioning time.
Realizing the potential The secret to realizing the full potential of our technology lies in our corporation’s Champion Concept. Almost three years ago, Bob Emery, Instrument Supervisor, PotashCorp NB, developed the vision for MARCH 2014
specialization. He saw that with the number of technologies PotashCorp was implementing, there wouldn’t be enough time to train all technicians in all technologies. He also recognized the frustration he was seeing on his team, so he began developing champions for each technology. Specialization brings other benefits for PotashCorp NB. The champion model increased our ability to respond more quickly and solve problems in-house. For example, the event logger was frequently overloaded because we had difficulty understanding how alerts propagated through integrated DeltaV, AMS Device Manager and ValveLink applications. Our in-house technology champions and others performed testing and gained a thorough understanding of how alerts are processed. Working together, we created a guideline for configuring alerts in DeltaV. The approach allowed us to prevent nuisance alerts and filter by transmitter or card-level. This led to better alarm-management and reduced the burden on the event logger. In addition to the benefits obtained by the company, we benefit professionally. Although initially the change was difficult, specialization allows us the time to hone our craft, develop deeper knowledge and engage our creativity. We invested the time upfront to make significant changes in our maintenance practices. What we gained is confidence that we are monitoring the right assets, solving problems more quickly and giving our technicians what they need to do their jobs well. Our practice will continue to evolve, but now we’re ready for the plant growth that lies ahead. Matthew Fenwick is an Instrumentation Technician for PotashCorp of Saskatchewan, in Penobsquis New Brunswick, Canada. A graduate of the Industrial Control Technology program, he has worked in mining and pulp and paper industries for the past 10 years. For more information on his success story, email Matthew.Fenwick@potashcorp.com.
Some caveats With the ISO-5500 Asset Management Standard, it’s more important than ever for operations to accurately define and document their critical equipment assets. A roadblock for facilities that haven’t yet completed this “must do”—or started on it—may be one of direction: What approach works best? While you can find plenty of tools, checklists and helpful advice on making critical-equipment determinations, keep in mind that they don’t reflect universal solutions. What’s appropriate for one type of operation may not be for another. There are several factors for a site to consider before adopting a specific strategy, including its industry sector and any standards related to the assets used in it. Do your research. An additional caveat comes from Doc Palmer, author of McGraw-Hill’s Maintenance Planning and Scheduling Handbook. While he applauds the use of criticality rankings in developing maintenance strategies, he cautions operations to not let those rankings complicate the reporting and addressing of the work itself. According to Palmer, personnel writing work requests need a simple way to communicate urgency based on time. “If we’re not careful,” he says, “injecting the criticality ranking into some calculated equation could hinder the ease of this important communication.” (Palmer’s article “Simplify Your Priority System,” from the May 2010 issue of this magazine, discusses various priority systems.)

Program success now and later...
Sustaining Operator-Driven Reliability
Jane Alexander, Deputy Editor
Research shows that ODR success can be elusive. Here’s how to make it work. It seemed like a good idea. Everybody appeared to buy in. Big investments in time, resources and technologies were made; considerable thought, communication and hard work were applied. Finally, everything came together: Your site implemented Operator-Driven Reliability (ODR). Congratulations! But how is it working for you now? ODR (the formalized involvement of operators in a facility’s asset-reliability efforts) isn’t new. Typical operator activities can range from collecting electronic data on vibration, temperature and the like, and noting abnormal equipment conditions; to performing routine replacements of gauges and other devices and helping technicians verify shutdown procedures; to assisting with equipment testing. Operators do NOT conduct data analysis within the scope of ODR. While this brief description of what ODR is and isn’t might seem straightforward, some plants have found the process to be more challenging than they expected. According to experts, one of the biggest challenges organizations face is how to sustain an ODR program. Research conducted by bearing-maker SKF—an ODR pioneer, having helped implement and sustain it in hundreds of operations around the world—has uncovered several reasons why (see Chart). They include: inadequate preparation prior to implementation; a change in or lack of management; changing corporate initiatives; technology barriers; even sabotage. But these roadblocks can be overcome. “Sustaining ODR doesn’t have to be a struggle,” says Dave Staples, SKF Global Services Manager for Traditional Energy. As with any other important enterprise initiative, a key to achieving success in ODR is to approach it as a process, not as a project. “Projects have ends,” explains Staples. “Processes live, grow and improve.” In Staples’ experience, rigorous, informed upfront planning is necessary for ODR success. His recommendations include: Clearly define and communicate goals and objectives. Because operational needs and goals differ, it’s important to align ODR with corporate business goals. Also, ODR goals and objectives must incorporate current reliability strategies, practices and philosophies. MARCH 2014

Typical Obstacles to Sustained ODR (source SKF)
Ensure cross-discipline support. Staples reminds plants that to have an impact on asset and process reliability and performance, an ODR program needs support not just from Maintenance and Operations, but from the Engineering and Reliability organizations as well. Obtain commitment from the plant floor to the executive suite. Management provides credibility for ODR and ensures funding and resource allocation. It also confirms ODR as a company priority. “It’s critical to identify ODR supporters and potential non-supporters early on,” says Staples, “and know where to look for improvement opportunities.” Because ODR is a process that operators will own, they should be involved in and committed to it from the start, even if they’re unionized. Identify a sponsor or champion from within the operations team whom all operators respect.
Plan for resistance to change and how to deal with it. Pushback on ODR can come from many sources, requiring several different management responses. According to Staples, responses can include reward and recognition for workers who are doing the right things; following compliance measurements and using the findings to drive corrections; supporting operator findings by correcting abnormal conditions quickly; and engraining the ODR process and findings into daily operations by hosting weekly status and planning meetings. Embed decision support. Embedding knowledge allows operators to make better decisions without requiring basic guidance from the plant’s skilled workforce. For example, Staples says that with an automated fault-diagnosis process and the use of decision trees and Boolean logic, operators can be directed to collect additional information leading to the root cause of a problem.
ODR Supports Business Excellence Operator-Driven Reliability complements Business-Excellence (BE) programs in several key ways: Empowerment is reinforced because operators have ownership for their equipment’s reliability. With this responsibility comes the ability for operators to initiate decisions for actions based on abnormal conditions they uncover. Standardized work is managed through technology. The idea of BE programs is for all operators in a facility to work according to defined principles. Operator ODR rounds are detailed in the inspection technologies they use (i.e., what machines to inspect and how; what abnormal conditions look like; and what to do next). And as operator informa
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
tion progresses from paper to digital form, it is shared faster, allowing for quicker corrective actions. Whether a site is implementing a new program or assessing a current one, the ODR process forces an environment of continuous improvement, driving inefficiencies and waste out of the system and putting the focus on high-value activities, a BE fundamental. Teamwork is promoted by both BE and ODR. When ODR is appropriately planned, implemented and managed, equipment reliability becomes an enterprise-wide endeavor. Working as a team, people throughout the organization— regardless of department, title or specific responsibilities— can truly impact reliability improvements. MARCH 2014
Develop and track appropriate key performance indicators (KPIs). Organizations often overlook important metrics associated with ODR, either by putting them off until after implementation or not tracking them at all. Without KPI’s, says Staples, “The ability to justify, learn, improve and optimize is lost.” He recommends that KPIs be established as early as possible in the implementation process to allow benchmarking of current status and measuring of improvements. “Make them readily available to those responsible for ODR at the site,” he says, “so they can track the results of their efforts or the need for corrective actions.” Because KPIs will drive the direction of ODR efforts, it’s imperative to review them regularly and confirm that they continue to help achieve the company’s strategic goals.
One of the most important things a site can do around ODR is
Staples also encourages sites to:
The Two Levels of Operator Feedback The type of feedback an operator receives and how it is delivered will impact his/her response. There are two levels of operator feedback, each designed to elicit a specific response: The first level explains the need for an inspection process relative to possible present conditions, causes, related problems and consequences. The second level uses documentation, graphics and photos to drive immediate action. These elements should be available via on-board memory or through the Wi-Fi capabilities of mobile devices. Be creative in your approach to feedback. The goal is to simplify operator input and minimize the typing of inspection results.
to manage expectations from the outset. Have a program life-cycle cost plan. Mobile technology changes quickly. Plan to replace hardware at the end of each cycle. Staples says that although
there will be incremental changes to technology throughout every life cycle, they’ll generally be software-related. Annual maintenance agreements guarantee sites that they will always have the latest version of software and access to new features during a life cycle.
Automate ODR with technology, but keep technology transparent. Provide effective levels of operator feedback (see Sidebar). Standardize all best practices and share them. Plan for ODR expansion and how to pay for it. Maintain a detailed, living training plan. One of Staples’ most valuable pieces of advice regarding ODR is to manage people's expectations about it from the outset. Keep in mind that ODR is not intended to be a complete maintenance solution. While operators “inspect,” for example, they cannot be expected to “analyze.” As Staples wrote previously in this publication (Feb. 2007), “ODR is best considered a complementary practice, and is almost always part of a strategically applied maintenance plan to achieve asset reliability and availability aligned with a company’s business objectives.” This approach has weathered well over the years, and it will work for your ODR program, too. MT&AP
Reward, Incentivize, Recognize Deal with Pushback, Change the Culture Rewards and Incentives are integral parts of most culture-changing programs, including ODR, because they reinforce acceptable behavior. Examples include cash, trips and gift certificates; Operator of the Week/Month programs; and tie-ins to existing company initiatives, such as profit-sharing. Once a desired behavior becomes a required behavior, use of rewards and incentives can be minimized or eliminated. Recognition Programs are the basis for quantifying return on investment. They document the value proposition that ODR delivers to the business. MARCH 2014
In contrast to rewards and incentives, recognition programs must remain in place. Keeping them fresh means keeping them visible—on posters, in newsletters, through tradtional news outlets and via social media— and posting KPIs. Operator-Certification Programs can also be used to transition away from rewards to recognition. Additional certifications can validate operator rank or wages. Certification programs can be qualitative or quantitative forms of recognition. Quantitative programs, though, must have real dollars tied to them and should be tracked closely.

Service disruptions can be caused by anything from equipment failures, to bad weather, to heavy vehicle and pedestrian traffic. Our safe, efficient transport of nearly 200 million passengers annually calls for a rapid response to such disruptions, along with effective preventive and predictive asset-management practices and frequent customer communications.
Details in the data To keep everything running smoothly, we’ve implemented a technology system that incorporates data, smarter infrastructure software and analytics and both mobile and cloud computing. This system turns 91,000 different pieces of equipment—from trams to power lines and tracks—into 91,000 living, talking data points, some with data-transmitting sensors. The data, which is not only collected through sensors but also via employee and passenger reports, unlocks the visibility of vital signs to help us understand the health and efficiency of our network. Data collected about tram service and functions is hosted on one centralized system—IBM’s Maximo—and is accessible by certain employees to encourage cross-organization collaboration. Using IBM Smarter Infrastructure software, different functions can analyze the data to garner information about improving response to maintenance issues, preventing service delays and re-routing trams. Insight gathered from the software is also used to send work-order alerts to maintenance teams.
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
Maintenance workers remotely access work orders and receive up-to-date asset information on mobile tablets, helping to improve repair management and respond quicker to potential disruptions. After a work order is completed, maintenance crews use the tablets to log how much time was spent on a repair and details about any follow-up that may be necessary. Repair logs are then used to identify trends and triggers that cause delays that can be avoided with predictive maintenance. Trends or patterns in tram and infrastructure repair history are identified through data analysis and used as a guide for scheduling predictive maintenance, which minimizes service downtime by enabling maintenance teams to fix equipment before it breaks.
Responding to an out-of-shape wheel: An automated wheelmeasurement machine detects a tram wheel that may have become out of shape after wearing over time on tram tracks. Information about the impending repair need is used to alert maintenance crews, who complete the work and can record all details on a mobile tablet. The repair log is compared to previous wheel repair logs and used to schedule preventative maintenance. Keeping trams running rain or shine: Melbourne has an annual rainfall of more than 24 inches, and it is common for some streets and tracks to flood when it rains. Collected data has indicated problem-prone areas, enabling maintenance crews to take precautions to prevent flooded tracks. Additionally, if tracks do flood, response crews are quickly alerted via mobile devices, making a quick response possible before service is delayed. MARCH 2014
Embedded in the tracks, smart sensors like these provide a range of critical operational data, including information on needed tram maintenance.
Allocating equipment to accommodate heavy passenger traffic for special events: When events like the Australian Open tennis tournament are held, we allocate trams to specific areas where heavy passenger traffic is expected. Passengers are alerted about service changes via tramTRACKER. Deploying the technology system has been a gradual, ongoing process that has involved retrofitting older trams, equipment and
power substations with sensors, as well as building and installing new equipment, such as our E-Class tram. The E-Class trams are equipped with Wi-Fi to enable information about tram health and efficiency to be downloaded when a tram returns to the depot. The next-generation E-Class tram began carrying passengers in November 2013. The new technology system has also allowed our entire organization to transition from a paper-based asset-management system to IBM Smarter Infrastructure software. The enterprise-wide initiative has enabled us to consistently exceed our key performance measurements around tram service and punctuality. In October 2013, service delivery was 99.11% and tram punctuality 82.70% (against targets of 98% and 77% respectively). That was a great result given that 80% of the network shares road space with motor vehicles. The future of public transportation is wide open with opportunities to apply technology in innovative ways to improve efficiency and reliability, in turn boosting passenger usage and stakeholder confidence. The way Yarra Trams uses sensors, data, analytics, cloud and mobile technology today is just the foundation. We look forward to evolving our transit system to benefit from what technology makes possible. MT&AP

Fighting Clogs Efficiently at a Wisconsin Wastewater Station The growing popularity of single-use towels, baby wipes and other non-woven ‘convenience’ products has become a maintenance nightmare for water-treatment operations. It should scare any operation that requires clean water. 32 |
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
The scenic community of Waupaca, WI, is spiritually connected to clean water.
The Flygt N pump is lowered into the wetwell at the Crystal River Lift Station.
Not only is its name a translation of a Native American term meaning “clear water,” its wastewater facility is known as the Crystal River Lift Station. So community leaders were well aware of the irony when this facility became notorious for its three pumps becoming clogged with debris after their installation in October 2002. The 360-GPM Crystal River Lift Station is among the largest of Waupaca’s 12 sewagepumping stations. It serves more than 10,000 residents and 3600 connections whose wastewater flows to a 1.5 MGD regional treatment plant operated by Waupaca’s utility. After undergoing treatment, the effluent discharges into the Waupaca River. It was not uncommon, however, for the Crystal River Lift Station’s wet-well to accumulate a thick mat of disposable cleaning heads, various types of wipes, towels, grease and even a band of underwear elastic. The array of crud originated from the county jail, nursing home, middle school, elementary school, hospital and other connections upline from the station. “We experienced clogs as often as three times per day,” says Jeff Dyer, wastewater team leader. “The old pumps cavitated badly and weren’t reliable. They simply weren’t engineered to operate efficiently in that environment.” Waupaca’s utility faced a growing problem for the wastewater treatment industry: the increased incidence of ragging due largely to wet-impregnated and dry-electrostatic wipes popular for household cleaning and personal hygiene use. Unlike traditional woven material, these often porous sheets and cleaning heads are manufactured from polymer fibers or film. Manufacturers market many as single-use “disposable” products, which the general public often mistakes for “flushable.” When state lawmakers considered a ban on this new generation of products, trade organizations reacted. A 2008 report by the U.S.-based Association of the Nonwoven Fabrics Industry, INDA, called attention to how wipes that pass through residential sewers should flow equally through the wastewater collection lines and be compatible with accepted wastewater treatment plant operations. INDA and its European counterpart ENDA have since drafted guidelines that define what constitutes a “flushable” consumer product. The National Sanitary Foundation sponsors an independent validation service to test and certify a consumer product’s flushability. Although convenient tissue-like wipes rarely block residential sewer lines, they can strangle traditional lift-station pumps as their residual material entangles pump impellers and impedes or clogs intakes. Federal legislation that reduced the flush volume for residential plumbing fixtures to 1.6 gallons has only aggravated the problem for utilities. Many operators foresee the problem becoming as potentially serious as when disposable diapers first reached the market decades ago. Diapers, however, were large enough to block residential lines before they reached the street, which created work for many plumbers at homeowner expense. Consumer news reports and word of mouth eventually led the general public to recognize the difference between a disposable and flushable diaper.
Convenience products, inconvenient clogging At the Crystal River Lift Station, the fibrous waste from these products caused recurring overloads that clogged the recessed impellers of the facility’s former 10-HP pumps. Each clog required that a team from the four-man Wastewater Group within Waupaca’s Public Works Department be dispatched to clear the pumps. Blockages in the 26-ft.-deep wet-wells presented an inherently unhealthy environment, further complicated by seasonal weather challenges. The station’s repeated blockages and call-outs created schedule intrusions and added expense. The cost for a two-man crew sent to clear the pumps, for example, doubled to more than $31 per man-hour, including benefits. Typically, more than one hour was required to restore the pumps to operation. And if proactive monthly cleanouts exceeded MARCH 2014

the capability of the City’s Vactor truck, an outside contractor was called in with a more powerful unit that cost up to $1500 per cleaning. When the utility’s aging pumps eventually needed overhaul or replacement, the Wastewater Department favored the latter. Several types of pumps were under consideration when a territory manager for Xylem, the manufacturer of Flygt brand pumps, responded to the utility’s inquiry. The discussion about the recurring clogging eventually focused on a Flygt N pump as a promising solution. (Editor’s Note: N-pump technology has since been incorporated into Flygt’s line of Experior products.)
To demonstrate the reliability of N-pump technology, Waupaca’s Public Works Department was offered a “try and buy” opportunity in 2008: A 10-HP unit would be installed and operated on a 60-day trial basis. If it ever clogged, the pump would be removed, without debate, at no cost. Installation was simplified with the use of the existing pump’s rail-type mounting system. The swap met expectations by performing flawlessly during the trial. In fact, the trial pump was set to operate in permanent lead-pump mode instead of the normal one-third operating sequence. Since the pump was always operating, the trial period subjected it to a continuous 180-day operating test. During

The old pumps weren’t engineered to operate efficiently in today’s high-debris-laden environments. They cavitated badly and were unreliable.
Designed with Debris-Laden Flows in Mind The Flygt N pump was specifically designed to handle the growing challenges of today’s higher debris-laden wastewater flows. Its improved efficiency derived largely from a self-cleaning, semi-open, backswept impeller with a horizontally positioned vane. The design contributed to energy savings by eliminating the drag imposed on earlier pumps from debris build-up on recessed impellers. The N pump’s hydraulic design eased the passage of solids while self-cleaning the impeller vane leading

By eliminating impeller fouling, the pump prevents the steady build-up of fibrous material that can otherwise impose drag and compromise operating efficiency and energy use.

N pump technology and its adaptive functionality have since been combined in what the manufacturer now designates as its Experior line.
the test, the existing companion pumps continued to clog. This led the utility to procure a second N pump in 2009, and a third in 2012. The three 10-HP N-3127 pumps now operate in continuous sequence, with run times averaging 1.4 hours each during 11 cycles on a typical day. “The reliability of the replacement pumps has been excellent,” reports Dyer, who adds that the facility’s “day-and-night emergency call-outs in all types of weather are no longer a factor.” MT&AP

Increasing Electrical Safety in a Brewery An upgraded design for plugs and receptacles reduces shock potential in wet environments. Jane Alexander, Deputy Editor
Opening a successful craft brewery was the dream of a lifetime for Mike Stevens and Dave Engbers, who started Founders Brewing Co. in Grand Rapids, MI, in 1997. After some initial challenges, the partners succeeded at brewing a flavorful brand of complex ales with broad market and critical acceptance. Founders’ products are now available in 25 states.
To accommodate growth, the brewery recently needed to expand operations and increase the size of its production staff. Part of that effort involved enhancing worker safety. Despite the company’s excellent safety record, a brewery’s normally wet environment poses an ongoing safety issue with regard to electrical shock, particularly when workers connect and disconnect mobile pump carts. To address this issue, the company contacted local distributor J.P.Motors & Drives, Inc., who recommended Meltric Decontactor Series switch-rated safety plugs as a convenient and cost-effective means for improving brewery safety. While pumps, motors and conveyors are among the primary sources of accidents at breweries and other manufacturing operations, the danger level at breweries can be high due to a concentration of factors such as hot liquids, pressurized systems, confined spaces, caustic chemicals and electrical shock. According to OSHA, electrical-shock accidents at breweries have occurred while technicians work on energized equipment like power panels and motor controls. To combat this risk, Founders installed Meltric’s plugs and receptacles on mobile pump carts, keg washers, motors and other portable equipment. According to Director of Brewery Operations Alec Mull, the plugs “help prevent electrical safety accidents before they happen.” Many breweries use pin-andsleeve, twist-lock or bladed-style electrical plugs to connect equipment to electrical power—all of which can be dangerous for personnel working in a wet environment. That’s not the case with Meltric’s connector technology.
Alec Mull says Meltric's technology (inset) makes the brewery's pursuit of safety and productivity easier. MARCH 2014

It takes only about 15 milliseconds to break contact with these plugs. “Safety is a keyword at Founders,” says Mull. “We’re in a wet environment all day, and we don’t want to put our staff at risk. Meltric’s plugs were the most cost-effective and the safest product we could secure.” He adds that because the brewery does not always have an electrician on site, the plugs are convenient. Making and breaking connections with the Meltric plugs, for example, is easy. The work is done by an
Because making and breaking connections with Decontactor plugs is a Risk Category “0” operation, PPE is not needed.
“We sell Meltric products to businesses that use portable equipment,” says David Patchak, a representative at J.P. Motors & Drives, Inc. “And we tell them that if an outside contractor on their site attempted to disconnect an energized pin and sleeve plug, it would be an OSHA violation that the site, not the contractor, would be liable for should an accident occur.” Patchak believes Meltric eliminates this problem with the safety features it incorporates into its products (see Sidebar). 38 |
Their modular design and flexible mounting accessories allow Decontactors to be used in a variety of configurations, including, in-line, cord-drop or wall-mounted.
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
Worker Safety & Switch-Rated Functionality Meltric’s Decontactor switch-rated technology combines the safety and functionality of a disconnect switch with the convenience of a plug and receptacle. These features make Meltric plugs well suited for breaking electrical connections on the portable equipment that’s typically found in breweries. Safety is increased due to a design that causes load making and breaking to occur in an enclosed arc chamber shrouded by a safety shutter so users are isolated from live parts. The plug cannot be physically removed from its receptacle until the load is safely disconnected.
To obtain the functionality Meltric Decontactor of a disconnect switch within a plugs and receptacles plug, Decontactors are built with are Type 4X, providing spring-loaded, butt-style contacts watertight connections similar to those used on contac- for washing down tors and switchgear.

MARCH 2014
The time needed to break contact is about 15 milliseconds, and the quick-break mechanism is automatically reloaded when the plug is re-inserted. “Meltric connectors make the pursuit of both safety and efficiency much easier,” says Mull. “These are simple and safe devices.” MT&AP MAINTENANCETECHNOLOGY.COM | 39

Synthetic-Rubber V-Belts With High Heat Resistance Emerson Power Transmission’s Browning has introduced a range of raw-edge V-belts made from EPDM (ethylene propylene diene monomer), a synthetic rubber formulated for strength and heat resistance. The belts have a temperature rating of -60 to 250 F and are available in such commonly used v-belt cross sections as AX, BX, CX, 3VX, 5VX and 8VX Gripnotch. The EPDM-formulated belt rating is 110 degrees higher than industry-standard polychloroprene belts, making them suited for rooftop blower units, commercial kitchen or industrial process exhaust systems. The company notes that v-belts may reach 110-115 F while simply running in the sheaves at 72 F ambient temperature. When heat is concentrated under a solid metal guard and the ambient temperature rises, the 140 F limit for common polychloroprene belts is reached quickly. EPDM belts meet RMA (Rubber Manufacturers Association) standards for tolerances off the shelf and are static dissipating as well as oil- and heat-resistant. Emerson Power Transmission Florence, KY

OVERCOMING YOUR CHALLENGES
Power: Your Compressor‘s Gas-Mileage Rating Ron Marshall CET, CEM for the Compressed Air Challenge (CAC)
hen fuel prices rise, we seem to put more thought into the types of personal vehicles we purchase—specifically with regard to their future operating costs. The automotive industry has helped consumers make good buying decisions by developing a standard way to display fuel economy in miles per gallon (or liters per 100 km). A similar means of comparing air compressor and dryer efficiency was developed by the Compressed Air and Gas Institute (CAGI, www.cagi.org). CAGI’s standard way to rate the efficiency of rotary screw compressors is based on the ISO 1217, Displacement Compressors—Acceptance Tests Standard. CAGI test results are available to all manufacturers, whether or not they are CAGI members, for rotary compressors from 25-200 HP, and stand-alone refrigerated compressed air dryers from 200-1000 SCFM. The program third-party-verifies the information that participating manufacturers publish on the standard CAGI Data Sheets, which are then published on the participants’ Websites and in their product literature. The data sheets define operational and performance information used during the specification and application decision-making process.
CAGI (the Compressed Air and Gas Institute) offers a standardized means for comparing efficiences of different air compressors and dryers in the marketplace.
The test results show equipment ratings for specific power, capacity at full operating pressure, pressure at which the test was conducted, full-load package kW, and kW at zero flow. Like a gas-mileage rating of an automobile, the specific power number is related to the efficiency of the tested compressor. The specific power rating shows the amount of power (kilowatts) consumed by the compressor for every 100 cubic feet of compressed air produced by

the unit. The test results are published in a standard format and can be used by a compressed air equipment purchaser to compare compressors and air dryers for efficient operation and to assess how well their compressed air equipment is running. For example, one fully loaded 100 HP unit may be rated at 424 acfm at 25 kW per 100 cfm at 125 psi, compared to another compressor that might put out 430 acfm while consuming power at a rate of 22 kW per 100 at 125 psi. If you know this compressor will be running a certain number of hours per year fully loaded, you can easily calculate the difference in annual electrical power consumption. Comparison of variable-speed-drive (VSD) compressors also has been standardized. However, instead of limiting the compressor rating to full-load and no-load, the manufacturer is required to show the rated flow-versus-power numbers through the full compressor operating range. This information is also displayed as a curve that can be used to calculate the power consumption at partial loading conditions. These numbers can come in handy when auditing compressed air systems. Consider the following: If you know your compressors are rated at 20 kW/100 cfm but are actually consuming 35 kW/100 cfm, you can assume something may be wrong with compressor control and take corrective actions. More information on compressor ratings can be found at compressedairchallenge.org and in CAC’s Best Practices for Compressed Air Systems Manual.

Introducing Girls to Engineering Jane Alexander Deputy Editor
y ongoing passion for helping grow the highly skilled, technical workforce that industry needs now and in the future is stronger than ever. Thus, the invitation to spend several hours the evening of Friday, March 7, at the Siemens West Chicago manufacturing plant was something I couldn’t resist. The occasion was the facility’s 2014 “Introduce a Girl to Engineering” event. I jumped on the opportunity to attend— as did 150 girls, grades five through 12, and their parents and/or chaperones. It’s good that we did. Overwhelming interest in the program, fueled by word-of-mouth, social media and outreach to schools and Girl Scout groups, meant that some hopeful attendees had to be put on a waiting list. Girls and adults who were able to register had plenty in store for them—including a very up-close and personal look at the West Chicago facility during a production shift. The plant was an ideal venue for showcasing engineering in action. Opened in 1969, it supports Siemens’ Industry Automation Division by manufacturing motor control centers, switchboards, enclosed controls and definite-purpose contactors. Plant Manager Juan Carlos Rivero and his team were gracious, knowledgeable and efficient hosts. After all, this wasn’t the first such event at the site: It was the 10th.
Out of just over 2 million employed engineers today, only 200,000 are women. Jayne Beck, Manager of Motor Control Center and Switchboard Order Engineering at Siemens Industry, directed the evening’s activities. She introduced the program at the West Chicago plant in 2005. Only 15 girls attended that year. How times— and girls’ interests and self-confidence levels—seem to have changed! All eyes were glued on Beck as she welcomed this year’s record turnout. Opening with a discussion
of what engineers do and where they do it (i.e., just about everything and everywhere), she pointed to various rewards associated with engineering careers—including, as she put it, “getting paid to play.” She also cited some disturbing statistics, among them the fact that out of just over 2 million employed engineers today, only 200,000 are women. “Why,” Beck asked the room full of girls, “are we letting the boys have the good jobs?” Turning to look at all the bright, eager faces around me, I could see that she was well on her way to making the “sale.” The next couple of hours closed the deal! Breaking into small groups, attendees embarked on the factory tour—from engineering design to production, packaging, even shipping operations. Nobody in our group lagged or strayed—I bet it was the same for the others. There was too much to see, hear and interact with, including a demonstration by a team from FIRST (For Inspiration And Recognition Of Science And Technology) of the robot it had built for the FIRST Robotic Competition (FRC) program. (Siemens, by the way, is an active supporter of FIRST and FRC, and helps mentor teams around the country.) Later, the small groups reconvened and competed in their own hands-on “engineering” challenges. In the end, whether their spaghetti-marshmallow-and-duct-tape towers stood tall, their tinfoil boats stayed afloat, their Snap Circuits glowed or their paper airplanes flew, every girl at the Siemens West Chicago event went home a winner. Each carried with her a clear vision of how she, as an engineer, could change the world. According to Beck, encouraging girls to choose engineering career paths is important, not just for them and their families, but for others, Siemens included. “Having women in the engineering field,” she explained, “brings a diversity of experience and thinking to our plant. Diversity means that people have different ways of approaching things, and this brings a lot of value to the company.” Well said, Jayne, and well done, Siemens West Chicago. MT&AP

THE MANUFACTURING CONNECTION
Reliability and Asset Performance For Profit Gary Mintchell Executive Director
he one point you will hear from me as I set the direction of Maintenance Technology & Asset Performance magazine is that everything we work on—whether through division management, plant management, reliability, engineering, maintenance or operations—adds to the economic value of our company. What we do has strategic value. Let’s act that way. Surveying the information that has been provided in this space over the past decade or so, I notice a recent trend to include more than traditional maintenance product information by adding emphasis on reliability. This is a good thing. Let’s consider the real challenge we have. It is not just fixing things. It is not even simply reliability, which can also be viewed as just fixing things. The real problem is optimum throughput of product over time. We call that asset performance. There are many tools at our disposal to help us in our quest for optimum asset performance. Most now derive from digital and computational technologies. Certainly, today’s professionals must be thoroughly proficient with digital networking and all the diagnostics that are available. Controllers and field devices are now information servers. Using all this information becomes crucial. The tools for digesting, analyzing and presenting it may seem to be the same you have used for years. These tools, however, have also changed over time so that if you are not using the latest versions, you could be missing out. Computerized Maintenance Management Systems (CMMS), Enterprise Asset Management (EAM) and Manufacturing Execution Systems (MES)/Manufacturing Operations Management (MOM) applications have existed for years, but their powers have grown significantly. Better check yours. MESA International is an association for companies and individuals who develop and use MES solutions. Its long-running “Metrics That Matter” surveys have consistently shown that these software tools can help improve performance. This year, LNR Research conducted and analyzed the survey in collaboration with MESA. A recent blog
MAINTENANCE TECHNOLOGY & ASSET PERFORMANCE
post, http://blog.lnsresearch.com/blog/bid/194495/ How-Do-You-Compare-Annual-ManufacturingPerformance-Improvements, discusses preliminary results of the survey. Two of the results concern maintenance specifically: Average Annual Performance Improvement of Maintenance was 14.9%. Average Annual Performance Improvement of Compliance was 18.5%. The top metrics for maintenance include: Percentage Planned vs. Emergency Maintenance Work Orders and Downtime in Proportion to Operating Time. According to MESA, survey results indicate that “leading companies, especially those in asset-intensive industries, have learned that by focusing on improving maintenance metrics they can prevent expensive downtime and keep operations running at peak efficiency and safety. Enterprise Asset Management (EAM) software applications in combination with real-time condition monitoring information coming from MOM and Industrial Automation applications are enabling companies to operate in a more predictable fashion instead of a reactive/disruptive fashion.” Top metrics in the compliance category include: Reportable Health and Safety Incidents; Reportable Environmental Incidents; and Number of NonCompliance Events per Year. “It’s hard to argue that health, safety and environmental issues shouldn’t be at the top of everyone’s list for vigilance and ongoing improvement,” MESA concludes. “These types of improvements require ongoing cultural awareness, supported by constant visibility and actions to improve these critical business and social metrics.” What would you like to see in Maintenance Technology & Asset Performance in print and online?
