Failure cause and treatment of 600 MW unit steam pump booster pump

Abstract

Abstract:

Abstract:After years of operation,many defects appeared on the booster pump of Huaneng Tongchuan Zhaojin Power Plant,such as abrasion of pump cover interface,serious axial movement while low load,damage of bearings,leakage of mechanical sealed cooling jacket and etc.After analyzation,solutions and suggestions to those defects was indicated,which are effective to improve the unit operation.

Key words: Keywords:booster pump, bearing, axial movement, mechanical sealed cooling jacket
