Vibration from a motor and a pump. Misalignment and motor problems were the cause of vibration.
Vibration observations during startup of Carrier Chiller.
Plant personell stated they observed 40 mil vibration from thier
Fin Fan coolers. The fan structure was randomly surging at 40 mils and greater.
A rental boiler FD fan was operating at higher than expected vibration amplitudes. Unbalance was suspected
Unbalance was not the problem with cell D. Changes in the operation could be contributing to the bearing failures
Balancing a 5 cell cooling tower every three months was an unacceptable practice.
A 2500 hp induction motor driving a compressor was observed to have increasing 1X vibration.
