VIBRATION ANALYSIS

Back

Pinpoint's vibration analysis services provide monitoring of motors, pumps, and other reciprocating and rotating equipment. Some common problems include:

shaft misalignment
pump cavitation
rotating imbalance
blade pass frequencies
gear mesh frequencies
natural frequency resonance
cracked/loose rotor bar issues

Motor Pump

Typical motor and pump system. Damaged bearing due to electrical fluting was found by using vibration analysis.

Fluting

Bearing from motor, damaged from electrical fluting.
