hello every one;

I have many reciprocating pump "PMH" supplied by electric motors(45kw) "ABB" ( belt transmission).

I level of horizental vibration on the NDE motor nearing is 9.63 and 10.59 mm/s RMS on DE bearing. the spectum used to show the frequency 45hz, and there attached levels and frequencies of bearings vibration.


many thanks for every one could have a participation of dignosis.
