Vibration Analysis
Use of vibration signatures to identify rotating-equipment faults such as imbalance, misalignment or bearing damage.
Examples
- 01Vibration analysis of a fan shows a peak at running speed, a typical sign of imbalance.
- 02Each month, the reliability engineer reviews vibration analysis trends for the 40 critical pumps, fans and gearboxes.
- 03When vibration analysis shows the early signature of outer-race bearing damage, the bearing is replaced at the next planned stop, three weeks before failure.
