Good afternoon everyone,
I am back in search of guidance and wisdom, ok I need help.
My senior is out for a week and I am left to my own experience.
I took readings on a turbo generator yesterday that had me concerned last month with high axial vibration on the outboard sleeve bearing of the input shaft.
These readings are from a magnet mounted accelerometer which is not optimal for a sleeve bearing application but is used for condition monitoring.
Last month the readings came out to 11G's axially and this month they dropped to a bit over 6.
This month the horizontal has climbed to 12.6 G's and decreased axially.
The first question from anyone was did you reverse the sequence of readings, the answer is no.
All the readings are taken with a Emerson 2140 and the inspector feature
stated " Exceptional condition exist, no recognizable faults found"
Plain English for your on your own.
I have wave forms and spectrums I could place here but being that this is a sleeve bearing rather then a rolling element am I comparing apples to oranges?
