Practical Case Studies on Vibration Analysis: Real-World Solutions for Machinery Reliability
A primary ventilation fan at a processing plant began exhibiting elevated vibration levels. The overall velocity readings jumped from a baseline of 2.5 mm/s to over 11.2 mm/s RMS within a single week. The sudden increase triggered a warning alarm in the plant’s supervisory control and data acquisition (SCADA) system, threatening an unscheduled shutdown. Vibration Analysis Diagnostics
