(Table Source: A review of vibration analysis and its applications) Conclusion: Why Case Studies Matter

1. Case Study: Bearing Defect in a Paper Mill Drying Cylinder

What is Vibration Analysis in Predictive Maintenance? - I-care Practical Case Studies On Vibration Analysis Pdf

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

A standby motor fan at an industrial plant sounded faulty immediately upon its first startup after being idle. (Table Source: A review of vibration analysis and

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.

Upon inspection, the grease was found contaminated and separating, with noticeable "dents" or craters on the outer race. Large circulating water pumps (156

Operating a single pump reduced the back pressure significantly (from 30 ft to 10 ft of water), causing the pump to operate outside its design parameters and into a cavitation zone .

Large circulating water pumps (156,000 GPM) were experiencing premature impeller failure.

Practical Case Studies on Vibration Analysis Vibration analysis is a cornerstone of , providing a non-intrusive "window" into the health of rotating and non-rotating machinery. By measuring and analyzing vibration signatures, maintenance teams can detect mechanical anomalies weeks or even months before they lead to catastrophic failure.
