Analysis on the failure of water circulating pump and the protective measures

Abstract

Abstract: Boiler water circulating pump is the important auxiliary equipment for boiler steam and water circulating, because of having to bear with the impact of high temperature and high pressure water, its working condition is extremely wretched, while its failure would have serious influent on boiler operation. This paper analyzed three reasons which have made pump failures in the last 10 years: unqualified insulation craftwork of winding lead wire, halfhearted overhaul, unreasonable parameters and manners of operation and startingup/shuttingdown. After implementing the improved measures aiming at those problems, the failures times of boiler water pump have been reduced, and the reliability of the pump operation has been raised.

Key words: boiler water circulating pump, failure, reason analysis, measure
