Vibration Analysis and IN-SITU Dynamic Balancing

Abstract

Over the years machinery health management has become vital part of the plant operation. Earlier day’s machinery maintenance is only focused on reactive maintenance. In later stages, Vibration Monitoring is a critical component of any Predictive Maintenance (PdM) Practices. Vibration Monitoring and subsequent analysis has helped in identifying an earlier consequence of breakdowns. [1]The idea of performing Predictive Maintenance to perform maintenance on the machines they exhibit signs of mechanical failure has become known as Condition Based Maintenance (CBM). Condition Based Monitoring System (CBMS) is proven technology to be less costly than the failure. A simple Consequence of Failure Analysis (CFA) is made to justify preventive maintenance activities. This evolutionary process of machinery maintenance has allowed the maintenance operation to more “Proactive” than reactive in their maintenance tasking. This paper pertains to one such study made at M/s MRF Ltd, who is the leading the tyres manufacturer in India, on a Main Circulation Blower which extremely critical for their production. We have observed the machinery health condition based on vibration measurements and vibration analysis which really helped us in identifying a failure sequence. In-situ dynamic balancing of main circulation blower ,which focuses the importance vibration analysis to reduce the induced vibrations from unbalance forces and Significant reduction in the vibration levels and which increased the machinery availability for production.
