摘　　要：针对水布垭电厂2F机组进水口工作门频繁下滑问题,经专题分析研究认为,主要原因为闸门启闭机油缸密封件老化失效,致使油缸内油压不稳定,油缸上下腔可能存在窜油现象。经对工作门油缸部分进行解体,将所有密封件进行检查和更换,2F机组进水口工作门频繁下滑的问题得到了解决。Abnormal sliding of the 2F unit water intake gate is frequently observed in Shuibuya Hydropower Plant.Analysis shows that the fault is mainly induced by the aging and failure of the sealing parts of the gate hoist oil cylinder,resulting in instability of the oil pressure in the cylinder and possible oil leakage in the upper and lower chambers.Then,the oil cylinder of the gate hoist is disassembled and all sealing parts are checked and replaced.After the treatment,the sliding problem is successfully solved.
