Technology Showcase: Lubrication Solutions

0713techshow1Vibration Analysis & Lubrication: Natural Synergy

It’s difficult to argue against the importance of an effective lubrication program or the necessity of vibration analysis. Still, rarely do these two modalities actively work together. Instead, they’re often considered completely separate entities on a reliability flow chart. The good news is that an often-overlooked dynamic synergy can exist between a plant’s vibration and lubrication groups.

Here’s how
Vibration analysts are often troubled with a combination of too many pieces of equipment to check and too little time to do it. Lubrication groups, on the other hand, constantly struggle with proper lube techniques, how to correctly determine lubrication levels and when to schedule them.

An investment in acoustic lubrication and monitoring of bearings not only helps build an effective lube program, it also sets up a natural first line of defense against rotating equipment failure. The ability to discover equipment in the early stages of failures, between vibration analysis routes, can yield huge financial rewards. The acoustic lubrication method makes better use of a lube technician’s lubrication route—helping establish new routines that are based on time, but customized for each bearing’s actual lubrication requirement. 

 When vibration analysts begin to integrate lubrication technicians into their monitoring cycles, more rotating equipment is being monitored—more frequently. While the technology and procedures to acoustically monitor grease-lubricated bearings has been around for 20 years, it’s still a vastly underutilized method. A simple paradigm shift in the maintenance culture is usually all that’s necessary to begin taking advantage of two groups that already exist.

Industrial maintenance management is a daunting task, even in the best of times. Operations must continue to find creative ways to stay competitive while keeping costs down. Using existing manpower more effectively—with minimal investments in equipment and training—is a good economic move. Go ahead: Uncover an important natural synergy in your plant.

Uptime: Thoughts On Maintenance Leadership And Teamwork

bob williamson thumb thumbBy Bob Williamson, Contributing Editor

“Our division director is deploying a self-managed team approach in maintenance much like a transition two years ago in the production department. Our maintenance workforce is mostly older, with nearly 20 to 30 years of service, and very traditionally craft-oriented. We’re also deploying a ‘maintenance best practice’ approach for job identification, planning, scheduling, execution, documentation and improvement. The new role of maintenance supervisors is unclear, but it will not be supervision. Are we heading down a slippery slope with these new self-managed teams?”

Boosting Your Bottom Line: Three Cautions Regarding Drives

motor-decisions-matterOne common cause of wasted energy—and wasted money—around industrial facilities is the running of motor-driven equipment at full speed, regardless of the load. Installing an adjustable speed drive (ASD) can help by matching motor speed to application requirements. There are, however, some important exceptions. This article explores several situations where installing an ASD may warrant a second look.

Where Can Drives Save Energy?
ASDs can save energy if they are used in appropriate applications, are installed properly and if potential harmonics issues are identified and addressed. Generally, ASDs are recommended for centrifugal loads such as fans, pumps and blowers that operate at least 2000 hours per year; in systems where flow varies over time; and where valves, throttles or dampers are used to regulate the flow and pressure.

Where Are Drives Unlikely To Save Energy?
While ASD energy efficiency is typically high (approximately 97% at full load), they are less likely to save energy in applications where motor speed remains relatively constant over time. Below are a few more examples where ASDs are unlikely to save energy.

1.High-static-pressure installations: A system that is static head-dominated (open loop) is one where the pump is working to overcome gravity or elevation. Examples of these applications include boiler-feed water pumps, submersible pumps, above-ground pumps that operate with a high static-dominated pressure level and pumps that lift water to fill a reservoir. In these applications, ASDs may not achieve overall energy savings as a control option; however, they may make sense where the ASD is used to address water-supply demand that modulates continuously.

2.Poor sequencing: Some motor-driven equipment is designed and installed with sequenc-ing in mind. For example, cooling towers or evaporator fans are often set up in lead-lag fashion, a good practice where each fan immediately turns on and off based upon demand. Adding an ASD to the existing lead-lag configuration may consume more energy because the drive programming algorithm could activate multiple fans to start earlier and operate longer at a higher energy-consumption level. 

3.ASD functioning as soft starter: An ASD used solely to eliminate equipment failure at startup, or to reduce demand charges by soft-starting motors does not necessarily save energy. Soft starters can provide this functionality.

So What’s The Bottom Line?
In the right applications, drives can offer solid benefits. Be sure to ask your utility representative or a motor and drive expert about other application-specific considerations.

Don’t Procrastinate…Innovate!: ‘If I Only Had Time. . .’

ken bannister thumb thumb thumbBy Ken Bannister, Contributing Editor

According to William Penn, Founding Fore-father of Pennsylvania, “Time is what we want most, but what we use worst.” He could have been referring to us: Of all the resources available to the maintenance department, time is the most precious, yet often the most squandered and undervalued. 

We have become a rather contradictory society—one that embraces time-saving devices and strategies, but rarely has time to reflect on their value and the results of our efforts. Most maintenance departments now utilize some form of computerized maintenance management system (CMMS) for directing and managing day-to-day work, yet few successfully use the reporting side of the management software to understand the value and effectiveness of the work performed so that maintenance practices can be validated or continuously improved.

Automation Insider: Get The Most From HART

garymintchellBy Gary Mintchell, Contributing Editor

If you’re working in a process manufacturing facility, I’m willing to bet that you have instruments containing the HART communication protocol (www.hartcomm.org). This is a fact of life, even if you’re not using it.

The most typical communication for transmitters to control is via the 4-20 mA analog signal. This signal only gives the variation of a value from a process sensor, such as pressure, temperature or flow. Through calibrations, the loop controller or DCS knows the value in real time of that process variable. HART was the first of the widely adopted digital networks. Its adoption was primarily due to its characteristics—the digital information flows over the analog wires.
