摘要
裂纹及断斗问题一直制约着冲击式水轮机向高水头大容量发展，同时也是影响电站安全稳定运行的重要因素。在对云南以礼河电厂CJA475－170冲击式转轮裂纹及断斗原因进行分析时，总结出引起冲击式水轮机转轮裂纹的主要因素。为了减少裂纹的发生，最后提出了几项重要措施，以保证冲击式水轮机电站安全稳定运行。
The problem of crack and broken bucket restrict that Pe1ton turbine develop toward high head and large power all the way along. On the other hand, it is a important factor of effecting safety and stability of operation for power station. The main factor that crack on Pelton turbine runner are summarized, on the basis of analying the reason of crack bucket on CJA475-l70 Pelton runner for Yilihe power plant. Finally, several important measures are taken in order to reduce occurred crack and guarantee safety a...
