The bad flow pattern will make the efficiency of the pump unit drop. Meanwhile, because there are a lot of sediments in sewage in the forebay , the bad flow pattern will make sediments depositing freely and the sediment deposition will cause worse flow pattern.

同时，由于排污泵站进水水流中含有大量的悬浮固体颗粒，不良的前池流态会使泥沙更容易在前池淤积，而泥沙淤积又进一步加剧了前池流态的恶化。

In city , because the occupied area of the urban sewage pumping station is usually limited , the length of the forebay is inclined to be short and the diffusion angle in flow direction is big accordingly , which causes bad flow pattern, such as backflows ,vortices, etc.

城市排污泵站由于条件的限制，前池一般面积较小，扩散角较大，扩散段较短，因此水流进入前池后突然扩散，流态紊乱，易行成回流、漩涡等不良水流流态，从而影响水泵的工作性能。
