Condition Monitoring of Rotating Machines—Part 1: Latest Practices

D. B. Kulkarni

Abstract


The smooth and trouble-free continuous operation of the plant equipment need to be ensured for longer life of the equipment. The equipment in any plant consists of two main types, Static and Rotary. While static equipment does not have moving or rotary parts, like transformer, control panel etc., the rotary equipment is constantly rotating. This rotation or relative motion causes wear and tear, that leads to deterioration of the condition of the mating parts in particular and the machine in general. While it is not possible to avoid the wear and tear as well as the deterioration of the machine performance totally, the same can be reduced to a large extent by timely and proper maintenance. The criticality of the equipment and the availability of standby options decide the overall maintenance strategy. The condition monitoring is one strategy that is being followed more and more worldwide for this purpose. It involves usage of various parameters to monitor the equipment health. This paper discusses various aspects of maintenance strategies involved in rotating machines and the latest advances in the condition monitoring field.
