肘形进水流道在大中型立式泵站的应用最为广泛，但在工程实践中对肘形进水流道的水力设计还存在一些问题。通过对采用立式泵装置的南水北调东线一期工程14座新建大型泵站肘形进水流道的控制尺寸进行分析，得到了肘形进水流道控制尺寸取值范围的基本规律，提出以大型泵装置优化水力设计理论为基础，采用 CFD 方法对肘形进水流道进行标准化设计，同时辅之以模型试验的方法进行验证。最后，根据肘形进水流道的优化水力设计实例，对肘形进水流道标准化的要求提出了初步设想。

Elbow inlet conduit is w idely used in the vertical pump system of the large and medium size pumping stations. H ow ev-er, there are st ill some problems in the engineering practice of hydraulic design for the conduit. Control sizes of the elbow inlet conduit of 14 new ly-built large pumping stations in the first phase of eastern route of South-to-North Water Diversion Project were analyzed, and the basic rules of the control size range were obtained. It is suggested to conduct the standardization design for the elbow inlet conduit using the CFD method based on the t heory of opt imal hydraulic design for the large pump system, and to apply the model test to verif y the result s. Finally, according to an exam ple of the optimum hydraulic design for the elbow inlet conduit , the preliminary assumpt ion on the requirements for the standardization of elbow inlet conduit was proposed.
