But Run to Failure is not an Option Nearly all facilities Electric Motors are dominated by Seal
Due to the unpredictable nature of Sealed Bearing life this situation lends itself to On Condition monitoring and when the Grease has depleted and friction levels rise a targeted replacement program is implemented.
This strategy is not affected by Environmental & Grease variations and maximizes service life and gains optimal reliability.
Due to cost constraints stated above a strategy needs to be integrated into Lubrication technicians existing resource, and take approximately the same time.
A Report of any change in friction levels can then be highlighted to a Vibration Analysis program, and close attention can be made. Lubrication Activities must align closely to Vibration Analysis and communication is vital, but often not attempted. Back office analysis struggle here especially if off site and misdiagnosis is common.
This has analogies of Hospitals, where trained nurses do much of the monitoring, application of medication, tests, patient inspections and observations. Deviations are reported for Doctor rounds.
“SO SEND FOR NURSES”
This hospital strategy optimises skills, lower total cost of ownership, and gets a controlled outcome.
How to achieve this Strategy
A well known technology of Ultrasonics is well suited to measuring friction levels in Bearings and other components.
