high radial vibration at journal bearing of air compressor is constantly adding to our woes. we have already checked our VMS several times but found it working perfectly.
bently nevada 3300 VMS is monitoring the vibrations of our CLARK air compressor which has operating speed of 16000 rpm. this compressor has two casings LP and HP coupled through a gear assembely.
the problem we are facing right now is that the radial vibration of bearing at inboard of its HP casing remains at alarming level despite our complete checks of BN VMS including checking if any noise might be causing this and thorough inspection of bearing and shaft by machinery department.
we are still unable to comprehend that what might be causing this nuisance or perhaps actual vibrations. it would also be pertinent to mention here that the casing vibration always come out at acceptable level. we are using carbon brushes for grounding of compressor shaft.
would anybody help us out of this messy situation as it has started to really bothering us now. i would be further obliged if someone guide me to anyother online forum or URL where i can find details of machine vibration
