Reliability Question
Reliability Question
(OP)
Our reliability group would like to use their "Vibration measurement tools" to make shim movements on energized running equipment if they discover soft foot on a electric motor or steam turbine, Is this a industry standard? I'm told it is at one bolt one shim movement at a time until they correct the problem. I would like as much input on this subject as possible, We have concerns.

/// Or ////, inferred when vibration changes when the hold down bolt is loosened or tightened?
What is the frequency of the vibration being monitored and attributed to soft foot?
There have been a raft of discussions by practical folks about real-time hold down bolt loosening on a variety of machines over here -

I don't think any equipment manufacturer would condone it, if only for liability concerns.
