Making It Home For The Holidays And More

As we get around to putting a bow on our December issue each year, I tend to cast about for some holiday-esque theme to put smiles on your faces. This year, I thought you might be interested in my year-end plans… I’m outta’ here (Chicagoland) soon, bound for the Rio Grande Valley of Texas to spend a couple of weeks with my little mamma and wonderful brothers. 

With another year drawing to a close, I’ve updated my version of this holiday treasure by weaving in themes from my 2012 columns: Asset management, PAS-55, reliability, work instructions and training, to name a few. Keep in mind that the underlying story is a fantasy (despite many readers’ experiences with some of the incidents cited in it) and, as St. Nicholas points out in the end, that there’s hope for all of us.

When times are tight, it can be tempting to skimp on the maintenance associated with your compressed air system. Replacement of parts and consumables associated with compressor lubrication, filtration and belt-drives are items that are sometimes put on hold if budgets are stretched. Ignoring maintenance on your compressors, dryers and filters, however, can cost you more than you think.

The Compressed Air Challenge’s comprehensive Best Practices for Compressed Air Systems Manual discusses this subject, indicating that, like all electro-mechanical equipment, industrial compressed air systems require periodic maintenance to operate at peak efficiency and to minimize unscheduled downtime. Inadequate maintenance can have a significant impact on energy consumption through lower compressor efficiency, air leakage or pressure variability. This can also lead to high operating temperatures, poor moisture control and excessive contamination of any product that comes in contact with wet, contaminated compressed air. Fortunately, most problems are minor and can be corrected by simple adjustments, cleaning, parts replacement and elimination of the adverse conditions. Compressed air maintenance is similar to that performed on automobiles: filters and fluids are replaced, cooling medium inspected, belts adjusted and leaks identified and repaired. 

All equipment should be maintained in accordance with its manufacturer’s specifications. OEMs provide inspection, maintenance and service schedules that should be followed strictly. In many cases, it makes sense from efficiency and economic standpoints to maintain equipment more frequently than the intervals recommended by manufacturers—which are developed primarily to protect the equipment.

One way to tell if a system is being well maintained and operating properly is to periodically baseline it by tracking power, pressure, flow and temperature. If power use at a given pressure and flow rate goes up, the system’s efficiency is degrading. This baseline will also let you know if the compressor is operating at full capacity and if the capacity is decreasing over time. On new systems all appropriate measurements should be initially recorded once the system is set up and operating properly to establish a reference against which all other baselines can be compared.

Proper maintenance is essential for compressed air system efficiency and reliability. The key is for compressor operators to be trained on the specific requirements for each piece of equipment, necessary resources and maintenance scheduling based on manufacturer recommendations and trend analysis of recorded data. All observations and meter readings should be recorded for compressors, dryers, filters and any other important components within the compressor room. A combination of equipment control-panel data backed up by frequent inspections and log sheets is mandatory for avoiding unscheduled system shutdowns and leveraging best-practice preventive and predictive maintenance. It’s critical to record the dates of all maintenance and repairs and to include a list of all parts that are replaced and/or all services that are performed.

An example of the cost of poor maintenance involves filter differential. On a typical system with a continuously operating 100 hp compressor, it would cost about $1500 per year in additional energy to overcome an extra 4 PSI of main-filter differential caused by poor maintenance. MT

2012 In Review: 

If we had to pluck one theme from the recent elections and apply it to this month’s year-end review column, it might be the “Are you better off?” question. For the record, I didn’t ask our Reader Panelists to assess 2012 using this particular yardstick. If I had, it appears the predominant answer would have been “yes.”

Next-Generation, Extended-Life Contamination Control Products

Air Sentry® is a leading developer of contamination control products that keep particulate matter and excess moisture from the headspace inside vessels like gearboxes that hold lubricants, greases, hydraulic fluids and fuels. This extends the life of critical machinery and equipment, and significantly reduces lifecycle costs. The company’s innovative products have been the gold standard in contamination control since 1997. Its line includes nine series of desiccant breathers, anodized color-coded closed system adapter kits that prevent cross-contamination, manifold adapters and pressure-vacuum-indicating gauges. 

Air Sentry has recently introduced a revolutionary new line of desiccant breathers called Guardian™. These “next-generation” contamination control products are the first breathers constructed of Tritan™. This patented material provides the most chemical-, temperature- and impact-resistant casing on the market. Guardian also is the first desiccant breather to incorporate an isolation check valve that protects the adsorbent from exhaust air and volatile splashing fluids. This lengthens the desiccant’s service life and reduces replacement frequency. Learn more about how Guardian increases fluid life, improves lubrication and lowers maintenance costs by visiting

It's an area where the one-size-fits-all approach doesn't work.

Symptom:

“Dear Dr. Lube, we’re looking for ways to reduce the significant purchase and disposal costs of lubricants used in our plant. Can you suggest some strategies for extending lubricant life?

Diagnosis: 

If a lubricant is to lead a long, productive, healthy life, it must combat dirt, heat, moisture and apathy. 

Heat directly affects the oxidative (useful) life of the lubricant, and for every 18 F degree temperature rise, the oil life expectancy is halved. Moisture attacks the base oil and prematurely strips out the additive package, causing sludge and oxidation. Dirt clogs filters, creates sludge and destroys machined surfaces. The prescription below can enhance your lube program, reduce operating and maintenance costs and improve your energy efficiency and carbon footprint.

Prescription: 

• Work with a Lubricant Management Specialist and perform a Lubrication Operation Effectiveness Review (LOER) to establish improvement opportunities in the applying, purchasing, storing, transferring, dispensing/metering and disposing of your lubricants.
• Work with your supplier to implement a Lubricant Consolidation Program that reduces/optimizes the number of lubricant SKUs used in your plant.
• Use professional-grade, dedicated transfer and delivery equipment to combat cross-lubricant contamination and dirt contamination.
• Implement a condition-based approach to managing lubricant application (engineering your lubricant delivery, i.e., when and how much?) and changeout requirements (performing oil analysis, i.e., how often?) 
• Implement a Machine Cleanliness Program to quickly identify leaks and moisture invasion, and to prevent dirt from contaminating the lubricant and forming a thermal blanket that raises lube temperature.
• Review your filtration methods and look for opportunities. 
• Take a 5R approach in tuning up your methods and systems to ensure that the Right person applies the Right amount of the Right lubricant in the Right place at the Right time.
• Train and certify your maintenance personnel, engineers and lube technicians to recognize the impact and cost of poor lubrication practices. MT

The Nidec flagship brand, U.S. MOTORS®, has a 100-year history and a strong reputation in industrial motors. The U.S. MOTORS brand is a bridge from a rich, solid past to a bright and expanded future. Today, Nidec Motor Corporation is committed to developing new technologies and products that help our customers solve problems, improve efficiencies and protect the environment.

Leading with a New Line of Inverter Duty Motors

A perfect example of how Nidec is leading the vertical motor industry is the recent introduction of a new line of stock Vertical HOLLOSHAFT® inverter duty motors with a bearing protection system to help mitigate bearing problems caused by shaft voltage. 

The use of inverters in pumping applications has increased dramatically over the past few years. The combination of an inverter and induction motor with a pump produces an economical variable speed drive system that has the potential to provide energy savings and process optimization. It may also lead to improved system reliability.

Unfortunately, inverters can be tough on electric motors. Those used to supply adjustable frequency power to induction motors do not produce sinusoidal output voltage waveforms. 

Most inverters use a control topology called Pulse Width Modulation (PWM) to change the voltage and frequency of the power applied to the motor. The switching frequency of the PWM control system generates steep-fronted voltage spikes that can damage motor insulation. 

U.S. MOTORS was the first to recognize the need for special inverter duty insulation system and introduced our Inverter Grade® Insulation system. This system meets NEMA MG1 Part 31 insulation requirements for inverter–fed motors. 

PWM inverters also generate common mode voltage, which may produce a shaft voltage. Shaft voltage can result in bearing currents that may damage motor bearings. Motors 40 horsepower and larger now include a shaft ground ring to short-circuit current that can damage bearings. 

While the number of occurrences of bearing damage due to shaft voltage is small, the cost to replace failed bearings is high. Reducing these types of field issues not only benefits the end user, but the pump OEM as well.

Its new inverter duty motors are just one example of how Nidec Motor Corporation continues to reinforce its reputation as a true innovator in the motor industry.

Today, we continue to revolutionize the power-tool industry by focusing on our core professional users and providing new technologies, such as Milwaukee’s REDLITHIUM™ battery technology, that lead to greater efficiency on the jobsite. In a crowded marketplace, success requires innovation.  

This year, Milwaukee introduced the new M12 FUEL™ line, expanding the industry’s largest sub-compact battery system to the next level of performance and durability. Six unique drilling and fastening tools will feature Milwaukee’s POWERSTATE™ brushless motor, REDLINK PLUS™ intelligence and REDLITHIUM™ battery technology, resulting in superior application performance.

“Our innovative M12™ lineup gives users new options, providing compact and lightweight power tool solutions for what was previously performed with hand tools,” says Mark Senske, Goup Product Manager, Milwaukee Tool. “Bringing our popular FUEL™ design into the mix of available 12-volt tools gives users even more options that deliver unmatched power, runtime and durability on the jobsite.” 

Not stopping there, the M12 FUEL™ line will feature Milwaukee’s other big news of the year—the introduction of their next generation of Lithium-Ion with REDLITHIUM™ 2.0 and XC4.0 batteries. 

“Milwaukee Tool,” Senske explains, “is dedicated to providing the best tool and battery technology to our users. With up to twice the run-time, 20% more power, two times more recharges than standard Lithium-Ion batteries and the ability to operate in climates below 0° F, this next generation of Lithium-Ion will allow our users to focus more on getting jobs done and less on charging their batteries.”

In addition, with more buildings implementing complex process-control automation equipment to manage new systems, measuring tools that identify problems before they occur, and in a time-efficient manner, have never been more important and needed. At Milwaukee Tool, this provides a window of opportunity.

“Our focus is on pro-viding users with inno-vative, high-performance solutions that increase productivity on the job-site,” says Ernie Racenet, the Marketing Director of Milwaukee Tool. “An example of this is a new Milliamp Clamp Meter launching soon that will allow facility engineers to measure 4-20 milliamp signals without breaking the loop, saving the user a tremendous amount of time and money. What used to take minutes can now be done in seconds.”

Another example of an innovative, high-performance solution is Milwaukee’s M12™ 160x120 Thermal Imager. Launch-ed earlier this year, it’s the ultimate predictive maintenance tool. A display features high-resolution thermal images for simplified diagnostics, while a visual camera captures photos right on the device. This provides users with the best information available, every time, no matter where they are, allowing them to schedule maintenance during downtimes.

Milwaukee Tool understands the importance of streamlining operations no matter what the company size, and having the right tool to do the job can make a big difference.
