| 摘 要： | 反水锤是发生在反击式水轮机尾水道中的一种特殊水锤现象，其压力峰值可达正常压力的几倍，甚至十多倍，以致造成肢解转轮、折断导叶、破坏顶盖、抬起转子的严重事故。因此，研究反水锤发生的原因，从而提出防止反水锤事故的措施尤为重要。

| Abstract: | Back water hammer is a special water hammer phenomenon happened in the waterway of reaction water turbine's tail.The peak value of its pressure can be several times of that of normal pressure,even more than tenfold.Serious accidents are caused such as turning wheel is dismembered,guide blade is broken,top cover is damaged and rotor is lifed.Therefore,it is quite important why back water hammer is caused,thus improve the relevant measures to prevent back water hammer accident from happening. |

| Keywords: | reaction water turbine back water hammer pressure regulating valve guide blade |
