立式泵装置进水流道演化数值分析研究

Research on an evolvement method for suction box of pumping system by numerical computation

针对各种典型的进水流道,应用紊流模型对流道内部流态及水泵进口处的流动进行三维数值计算,计算结果表明各种流道内部水流流态相似。数值分析显示各种有压的喇叭管进水的流道都是在开敞式进水池形式基础上演变而成的,只要控制流道的基本尺寸,就可将各种喇叭管进水的流道统一起来。研究成果为泵站进水流道优化设计提供新的思路。

Numerical computation of the turbulent flow is made to applied the flow field in different kinds of suction box. The results indicate that the flow patterns are similar to each other. The different kinds of suction boxes are evolved from the opening pump sump, so, they can be united if they have essentially the same controlled parameters.
