Abstract

Abstract: The structure features of the MDG366 type feed water pump were introduced. Due to collision and friction, the balancing sleeve of the feed pump had dropped; and this caused the throughflow of the pump interrupt; so a serious thrust bearing overburning accident had occurred. The process of the accident was described. The reason of the accident was analyzed. Some relevant treatment measures were adopted, and the design was improved successfully. The maintenance and operation measures for preventing similar accident were put forward.

Key words: feed water pump, vibration, friction, thrust bearing, accident
