凝结水泵出力不足的问题排查、分析与处理

Analysis and Treatment on Condensation Pump Output Insuficient

离心泵是化工、电力生产中的重要输送设备,凝结水离心泵(凝结水泵)是电厂中的重要辅助设备。某电厂在试运期间,在机组高负荷时,凝结水泵发生汽蚀现象。分析了凝结水泵发生出力不足的原因,并通过对凝结水泵入口蝶阀进行改造,消除了出力不足的设备缺陷,提高了凝结水泵运行的安全性和经济性。

Centrifugal pump is a kind of important transmission equipment in chemical and power production.Condensation pump is an important auxiliary equipment of power plant.During the trial operation in a power plant,condensation pumps occured cavitation problems when the tubine ran in high load.To analyze the reasons of condensation water pumps insuficient,reform the butterfly valves in the inlet of the condensation pumps,eliminate the shortage of equipments and improve the secufity and economy in condensation operation.
