PeakVue Plus Technology Indicates Off-the-scale Bearing Friction

PeakVue Plus Bearing Friction

PeakVue Plus – Bearing Friction

In this the third of three videos on PeakVue, James Sylvester shows that when the Emerson AMS 2140 is setup correctly, PeakVue Plus can detect issues with lubrication health, in this case, the bearing friction was off the scale! The asset in question is a critical plant fan on a variable speed drive with an operational speed of 1200rpm with 22224 EK Taper roller bearings installed.

Incorrect grease used

This short presentation shows how PeakVue Plus detected incorrect grease used by the contractor prior to any considerable bearing damage occurring. As part of the site maintenance annual shutdown the bearing caps were opened, the grease removed and it repacked with fresh grease. Watch as James explains how the PeakVue Plus technology helped confirm the root cause, (6 mins):

Yes, but the correct configuration with the correct PeakVue filters is needed. See our PeakVue course for more details

The best mounting is stud mounted, however in a walk around route you can use a flat rate earth magnetic on a clean mounting point.

No, PeakVue uses standard Accelerometers, however the best results are from a high end premium Accelerometer.

We do indeed! Students can choose from ISO 18436-2 CAT I to CAT IV. Courses are certified by BINDT or Mobius Institue. Study options include: Online, Public and Onsite. See the Vibration Analysis Courses page for more details.
