S109FA燃气机组直流油泵自动启动失败的处理方法

摘要

S109FA燃气机组正常运行时由380 V交流润滑油泵提供轴系润滑油和发电机氢气密封油；2台交流润滑油泵都故障时，直流润滑油泵自动启动代替交流润滑油泵工作；当发电机氢气密封油压力低于设定值时直流密封油泵自动启动，使发电机氢气密封油的油压力维持在合格的范围之内。本文介绍了直流润滑油泵和直流密封油泵在自动启动失败的紧急情况下的处理方法，为S109FA燃气机组和其它型号的燃气机组处理类似的故障提供参考。%S109FA gas power unit was provided by the 380V alternating current lubricant pump to fasten lubricant and generator hydro-gen to seal completely oil while it ran normally.While two alternating current lubricant pumps all broke down, the direct current lubri-cant pump automatic start instead of the alternating current lubricant pump.While the oil pressure of generator hydrogen seals was less than initial value, the direct current seal oil pump automatic start, which made the oil pressure in the qualified scope.This paper intro-duced direct current lubricant the pump and direct current seal completely an oil pump under the urgent circumstance that auto start failure of treatment.It can be a reference for the S109 FA gas power unit and other similar of the breakdown unit.
