转轮是水轮机的核心部件,其性能对水轮机的性能起着决定性的作用。百龙电站水轮机转轮投产不足5年就严重损坏,致使发电机组振动幅度大增,效率明显下降。文章根据电站运行实际情况和转轮损坏的现象,分析该电站水轮机转轮严重损坏的原因,并介绍修复措施,可供同类电站转轮修复借鉴。
The runner is the core component of the turbine and its performance plays a decisive role in the performance of the turbine. 100 Long hydropower runner run less than 5 years on the serious damage, resulting in greatly increased vibration amplitude of generating units, the efficiency dropped significantly. According to the actual situation of power station and the phenomenon of runner damage, the article analyzes the cause of serious damage to the runner of the power station and introduces the repair measures, which can be used for reference for the repair of runner of similar power station.
