摘　　要：进、出水流道是低扬程泵装置的重要组成部分,流道的水力性能对泵站的影响举足轻重,扬程越低,影响越大。本文介绍了西河泵站双向竖井贯流泵装置出水流道CFD水力优化计算过程;并根据水力优化计算结果,结合泵型、泵站运行年利用小时数、泵房布置等因素,经技术经济比较后确定了西河泵站出水流道设计方案。同时,对今后大中型泵站的出水流道设计提出了建议,以期为大中型泵站科研、设计等人员提供参考。Inlet and outlet flow channel are important parts of the low-head pump device. The hydraulic performance of the flow channel has decisive influence on the pumping station. The lower the head,the greater the influence. This paper introduces the CFD hydraulic optimal calculation process of outlet flow channel of two-way shaft tubular pump unit in Xihe Pumping Station. According to the results of hydraulic optimal calculation,and combining the pump type,annual utilization hours of pumping station and the layout of pumping house,the design scheme of the outlet flow channel of Xihe Pumping Station is determined after technical and economic comparison. Meanwhile,this paper puts forward some suggestions for the design of the outlet flow channel of medium and large pumping stations in the future,in order to provide reference for the scientific research and design personnel of medium and large pumping stations.
