摘　　要：针对某水电站1号水轮发电机组出现的转轮体轴套磨损及固定螺栓断裂异常等问题,根据固定螺栓断裂情况,现场测量的机组转轮体轴套、轮毂磨损数据,及有限元分析计算,深入分析了转轮体轴套磨损及固定螺栓断裂的原因,提出了处理方法,经处理改造后转轮体运行正常,效果良好。In the No.1 hydro-turbine generator unit in a hydropower station,abnormal wear of the runner shaft sleeve and fracture of the fixed bolts are observed.According to the fracture conditions of the fixed bolts,the on-site measured wear data of the runner shaft sleeve and the runner hub,and the calculation results of finite element analysis,possible reasons of the problems are determined,and treatment measures are proposed correspondingly.After the treatment,the runner body operates normally with good performance.
