百色水利枢纽3号机尾水闸门异常分析

Analysis of abnormal tail gate of No.3 unit at Baise Multipurpose Dam Project

尾水闸门主要包括门体、门槽、启闭机、钢丝绳等几大部件,涉及机械、电气、水工等相关领域。介绍了百色水电站3号机组检修时,出现的排水泵震动及尾水闸门漏水现象,查找并分析了漏水原因,认为是尾水闸门及底轨变形所致。提出了尾水闸门管理和维护工作中应注意的问题。

Tail gate mainly consists of gate body, gate slot, hoist and steel wire, incorporating mechanical, electrical and hydraulic fields. During repair and maintenance of No.3 turbine generator unit of Baise Multipurpose Dam Project, vibration of dewatering pump and tail gate leakage occurred. The cause of leakage was analyzed and it is concluded the deformation of gate and bottom rail led to the leakage. The authors put forward the issues in need of attention during operation and maintenance of tail gate.
