Lubrication Checkup: Greasing Your Motors

lubrication-checkupSymptom:
“As a greaser for an auto part manufacturer, I’ve noticed an increase in the number of replaced fractional and low-horsepower motors I now have to grease. Most of the replacement ‘offshore’ motors all have grease nipples, but they don’t seem to last as long as the ones without nipples. Any suggestions for grease amount and schedule for these ‘greasable’ motors?”

Diagnosis:
This seems to be a common dilemma in light of more fractional and low-hp motors coming from offshore suppliers. The majority of these units are fitted with one or two grease nipples to lubricate the motor’s bearings, yet, due to cost and physical motor size, relatively few have any form of lubricant drain positioned opposite the nipple(s).

Normally found in motors of 25 hp and higher—depending on bearing design and set up-most larger motors have drain relief ports located 180˚ opposite the greasing point. When greasing the motor, the lubricator is required to unscrew the relief drain port dust cap prior to lubricating the bearing. If the bearing is over-lubricated—as it most often is—the grease is allowed to benignly drain through the unsealed bearing and out the drain port. The lubricator then cleans the port and screws the dust cap back in place.

If the dust cap is in place when the bearing is lubricated—or no drain relief port exists—over-lubrication causes excess grease to bypass directly into the motor’s windings. This will start to hydraulically retard the motor, causing it to overheat and fail prematurely. Meanwhile, the motor will require a huge amount of additional electrical energy to overcome the fluid friction of the surplus grease.

Prescription:
Lubrication delivery system manufacturers who have been applying lubricants successfully since the 1920s have always subscribed to the unwritten rule NOT to lubricate motors of 50 hp or less that have sealed bearings. Because a rolling element bearing only requires 40% of its cavity to be filled with grease, “run-to-fail” strategies have proven more effective than “kill-it-with-kindness” over-greasing. With small and fractional hp motors, a very small amount of over-greasing can quickly become problematic. A better approach would be to replace the grease nipple with a plug and run-to-fail. MT

Viewpoint: The Importance Of Human Capital In PdM

jimseffrin1

Jim Seffrin, Director, Infraspection Institute

Savvy business professionals recognize the importance of capital when undertaking any new project. Failure to properly capitalize a project can have disastrous consequences—particularly when a business does not have the key resources it needs.

Unfortunately, in the aggressive marketing of predictive maintenance (PdM) technologies, it is relatively easy to spawn and perpetuate fallacies regarding the need for certain resources. One prime example is infrared thermography—often associated with the term ‘Simply point and shoot.’ Coupled with the promise of quick and substantial paybacks, facility managers will readily invest thousands of dollars in hardware and software, only to sometimes be disappointed.

To be successful with your PdM initiatives, it must be understood that such efforts (and technologies) are reflective of both art and science. As such, they require humans equipped with proper tools, appropriate training and sufficient field experience. Ample time to conduct testing and analysis also is needed.

Undercapitalizing manpower is often the greatest threat to PdM—and what can ultimately lead to program failure. In setting up a PdM program, the most common mistakes include inadequate staff and training and not enough time for data collection and follow-up testing.

When considering implementation of any PdM program, one must first begin by honestly assessing the amount of manpower required. For maintenance teams already working at capacity, it is unrealistic to expect that existing personnel will have several hours to dedicate to data collection and analysis each month. If necessary, consider adding personnel or redistributing responsibilities to ensure that technicians will have sufficient time available. In addition to technicians, companies must be certain to allocate or hire suitable support staff as well.

Because a PdM program is only as good as its technicians, training is crucial—something to be viewed as a long-term investment rather than a one-time minimal expense. When training is under consideration, make certain that course curricula are adequate for the intended inspections and taught by experienced instructors. Independent training firms may offer a better value than technology vendors since their focus is on training rather than future equipment sales.

While it is easy to focus on the promise of reduced downtime and labor, these are downstream benefits. The early stages of a PdM program demand significant time for data collection and analysis. Although some technologies can provide instant results, others rely on trending. In such cases, it may take several inspections to obtain meaningful data. In addition to data collection in the field, time must also be allocated for analysis and report generation. Depending upon the technology, report time might call for the same amount of time as data collection.

Once corrections or repairs have been made as a result of a PdM inspection, follow-up testing should be performed to ensure those actions were effective. Facilities that fail to re-inspect run the risk of an unplanned outage. Follow-up inspections are the final step in verifying that a problem has been solved.

To ensure their PdM programs are successful, companies should always seriously consider the necessary human capital—not just the hardware and software requirements. The proper investment in PdM technicians and support personnel can pay enormous dividends and help drive program longevity. MT
