进水池流态对泵进口流场的影响

Influence of the Flow Pattern in the Sump on the Flow Field of Pump Inlet

中小型泵站通常运用进水池来为水泵提供进水条件。进水池中流态的好坏直接影响泵进口的流场,从而影响到水泵的系统性能。介绍了国内对进水池流场研究的进展情况,论述了其对泵进口流场的影响,探讨了对进水池流场研究的方法,分析了各种方法研究的利弊。

Medium-sized and small-sized pump stations usually provide the water inlet condition for the pump with the sump. Therefore, the good or bad condition of flow in the sump directly exerts an influence on the flow field of the pump inlet and consequently leads to poor pump system performance. Studied on the development of the research on the flow pattern of sump and illustrates its influence on the flow field of pump inlet. The method of the research on the flow pattern in the sump is discussed. The advantages and disadvantages of the methods are analyzed.
