摘要/Abstract

摘要： 摘要：某新建电厂600MW汽轮机油系统在调试过程中发生了多起故障，主要原因为高压启动油泵停运后机组跳闸、交直流油泵联锁试验中润滑油压下降过大、顶轴油系统盘车脱开、密封油进入发电机内部、密封油差压阀损坏、高压抗燃油油温过高。对这些故障进行了详细分析并做出了处理，取得了较好的效果。

Abstract: Abstract:In debugging process of the 600MW steam turbine oil system of a newly-built power plant, several faults occurred, which include that the unit tripped after shutdown of highpressure startup oil pump, the lubricating oil pressure dropped too much in interlock test of AC oil pump and DC oil pump, the turning gear of the jacking oil system disconnected, the sealing oil entered into inside generator, the sealing oil differential pressure valve damaged, the temperature of highpressure fire resistant oil was too high and others. The faults were analyzed and treated, and better effects were obtained.
