漩渦氣泵的葉輪類似龐大的氣輪機的葉輪。With piv technology, the flow field was measured to judge the performance of pump sump. by analyzing the pictures of velocity, streamline, turbulent kinetic energy and vorticity, we found that the turbulence was bigger while the ratio of the runoff increased. and the vortices always appeared in the field where the runoff was small
通過piv試驗，測量了封閉式水泵吸水室內部的流場，以研究該水泵吸水室的性能； （ 2 ）通過分析流速圖、流線圖、湍動能圖和渦量圖，發現了流量比越大，湍動越大，漩渦總是出現在流量較小的一側。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. the bad flow pattern will make the efficiency of the pump unit drop
城市排污泵站由於條件的限制，前池一般面積較小，擴散角較大，擴散段較短，因此水流進入前池后突然擴散，流態紊亂，易行成迴流、漩渦等不良水流流態，從而影響水泵的工作性能。分享友人
