Please see the below vibration data of a centrifugal pump & share your analysis.
Interesting that the 20X is in the pump axial and essentially non existent in the motor horizontal direction. Can you advise what the bearing types are in the pump? What type coupling is being used?
Angular contact Ball bearing
Deep Grove ball bearing
Shim type flexible coupling
I see a 60 Hz frequency and a motor rated at 2945 rpm. Is this correct?
The data shows 6 inlet impellor vanes. Are these the rotating vanes?
Is this a variable frequency drive. If yes can u lower the speeds by 100-200 rpm and see what happens to 20X, if not switch off the machine and a take a waterfall diagram of Pump inboard and see the influence of 20X. will it follow a linear pattern/gradually reducing trend or suddenly vanishes as soon as u switch off the pump. Just find out from the pump drawing do u have anything related to "number 20", vanes/blades etc...or may be flow related issue.. need some more trouble shooting before u can conclude....
