摘要
主要针对1号机组发电机的密油系统大修后负压不正常、氢气纯度低的原因进行了跟踪分析,找出负压不正常、氢气纯度低的原因为空侧密封瓦磨损使密封间隙超标、空氢侧密封瓦窜油、R-4差压阀内部波纹筒损坏。采取了相应的对策和措施不力,使问题得以解决。
Regarding No. 1 Power generating unit oil sealing system＇s abnormal of minus pressure to after over haul, low purity of hydrodren, it analgsed it case, found that its empty side sealing tile wearing made sealing interval bigger, empty side sealing tile leaking oil, R-4 pressure difference inner ware damage, adopted relative measure.
