摘要
针对三峡左岸电站VGS水轮发电机组推力轴承运行时瓦温偏高的现象,介绍了VGS水轮发电机组推力轴承的结构、运行及技术改造情况,重点分析了瓦温与推力轴承工作特性之间的关系,这对三峡上游蓄水156m后机组稳定运行具有重要的意义。
According to the higher thrust bearing pad temperature of the VGS hydroelectric generating u- nits in Three Gorges Left Bank Hydropower Station,the paper introduces the structure,the operation sta- tus and the technical modification of the thrust bearing.Emphatically analyzes the relation between the pad temperature and the working behavior of the thrust bearing.It is of importance to ensure the operation sta- bility of the VGS units after the water level of the Three Gorges Reservoir rising to 156m.
