PG9171E型燃气轮机液压油系统2次泄漏的原因分析

介绍了PG9171E燃气轮机在新疆喀什应急电站调试运行中出现2次液压油系统泄漏的查找和处理过程。总结了＂在液压油系统发生泄漏时,辅助液压油泵会自启动;液压油系统的出口压力越低,辅助液压油泵电机电流就越小且泄漏点就越靠近油泵出口＂的经验,供技术人员处理同类问题时参考。

Analysis on reasons of two times leakage incidents of hydraulic oil system in PG9171E gas turbine

In Xinjiang Kashgar Emergency Power Station,during debugging and operation of the PG9171E gas turbine,two times leakage incidents were occurred in hydraulic oil system of PG9171E gas turbine.The finding process and treating process of the two leakage incidents were introduced.A conclusion was summarized,which is that when the leakage of the hydraulic oil system was occurred,the auxiliary hydraulic oil pump will start automatically;if the outlet pressure of the hydraulic oil system is lower,then the motor current of auxiliary hydraulic oil pump is smaller and the leakage point is closer to the oil pump outlet.The experience can be used as reference for technicians to treat similar problems.
