This is the predominant technology employed in condition monitoring to determine the condition of various mechanical components making estimating a prediction on service life expectancy and urgency of repairs.
It is a non-invasive technique which collects vibration data from machines under normal operating conditions. Vibration readings are typically taken at bearing locations following accepted industry.
Vibration analysis can detect problems such as:
- Bearing failures
- Mechanical looseness
- Resonance and natural frequencies
- Electrical motor faults
- Bent shafts
- Gearbox failures
- Empty space or bubbles (cavitation) in pumps
- Critical speeds
