贯流式机组转轮联轴螺栓断裂原因与对策

Fracture Causes and Countermeasures of Coupling Bolt of Runner of Tubular Unit

随着贯流式机组使用的增多,暴露出一些问题和缺陷,转轮联轴螺栓是连接机组大轴与转轮的关键部件,一旦出现螺栓断裂,后果十分严重。基于转轮联轴螺栓断裂问题,提出处理的方法。

With the increasing use of tubular units,some problems and defects have been exposed.The coupling bolt of runner is the key component to connect the main shaft and runner.Once the bolt is broken,the consequences are very serious.Based on the fracture problem of runner coupling bolt,this paper puts forward the treatment method.
