What is Vibration Analysis in Predictive Maintenance? - I-care

Impellers showed severe pitting, appearing as if attacked by "metal-eating termites". Vibration spectra showed broadband energy without distinct peaks—a classic sign of cavitation.

Converts time-domain signals into discrete frequency peaks to identify specific faults like unbalance (1x TS) or misalignment (2x, 3x TS). Practical Case Studies On Vibration Analysis Pdf

In a cardboard manufacturing facility, routine vibration measurements on a drying cylinder (rotating at 165 RPM) revealed an increase in amplitude on the drive-side bearing.

1. Case Study: Bearing Defect in a Paper Mill Drying Cylinder What is Vibration Analysis in Predictive Maintenance

The failure was identified as false brinelling , caused by external vibration sources in the plant vibrating the stationary motor's bearing over time.

Improved isolation of standby equipment from external vibration sources was implemented to prevent recurrence. 3. Case Study: Pump Cavitation at a Power Plant Case Study: Bearing Defect in a Paper Mill

Operational protocols were adjusted to maintain proper back pressure, eliminating the cavitation-induced vibration. Core Vibration Analysis Techniques
