摘要

通过分析

找出了洛阳首阳山电厂 2 0 0MW汽轮机EH抗燃油系统油压低的原因主要为伺服阀泄漏所致

而伺服阀的泄漏是由氯离子而引起。采取清洗系统、换油等措施后

问题得以解决

Abstract

Through analysis

the cause leading to lower oil pressure in EH fire-resistant oil system of a 200 MW steam turbine at Shouyangshan Power Plant in Luoyang City has been found

the main cause is due to servo valve leakage

however

the servo valve leakage is caused by chlorine ion. After adopting some measures

namely system cleaning

oil replacing etc. the said problem has been solved.
