水锤现象对泵站和输水管道的影响与防护——以万家寨引黄工程为例

Influence and protection of water hammer on pumping station and water delivery pipeline——Taking Wanjiazhai Yellow River Diversion Project as an example

不论是正常运行泵还是终止运行泵等都有可能对水流动性产生一定的影响。当压力较高情况下,可能会形成管道破裂,而当压力较低情况下,则可能会形成管道塌陷,甚至会对阀门以及固定物带来一定的影响。本文以万家寨引黄工程为例,研究水锤现象对泵站的影响特征,并提出了预防措施。研究成果可为水泵的运行管理提供参考。

Whether the pump is in normal operation or out of operation,it may have a certain impact on the water flow performance.When the pressure is high,it may cause pipeline rupture,and when the pressure is low,it may cause pipeline collapse,and even have a certain impact on valves and fixtures.Taking Wanjiazhai Yellow River Diversion Project as an example,this paper studies,the influence characteristics of water hammer on the pumping station,and puts forward some preventive measures.The research results can provide reference for the operation and management of pumps.
