电厂取水工程循环水泵突然开启和关闭时,取水口至泵房之间发生瞬变流动,特别是引水管道较长、流量较大时,水击的冲击力会引起管道系统中的压力脉动,前池水面振荡,严重影响取水工程的安全稳定运行。因此,研究取水口至泵房之间的瞬变流现象对于保障取水工程安全运行有着重要的意义。
When the circulating water pump in the water intake project of the power plant suddenly opens and closes, the transient flow occurs between the water intake and the pump room. In particular, when the water diversion pipeline is long and the flow rate is large, the impact force of the water hammer causes the pressure pulsation in the pipeline system. Pool surface oscillation, seriously affect the safe and stable operation of the water intake project. Therefore, studying the phenomenon of transient flow between the water intake and the pumping station is of great significance to ensure the safe operation of the water intake project.
