针对万家寨引黄工程用泵的运行条件，用有限元方法计算了立式单吸单级泵轮内的流场，并以陕西东雷南乌牛二级站的H4型水泵磨损情况为例，对万家寨引黄工程总干线一、二级泵站和南干线一、二级泵站采用单级泵时的磨损情况进行了初步预估．
According to the operating conditions of Wanjiazhai Yellow River Diversion Project, the flow field in vertical single suction single stage pump impeller was calculated by finite element method For example, a preliminary estimate was made on the wear status of the first and second stage pumping stations of the Main Route of Wanjiazhai Yellow River Diversion Project and the first and second stage pumping stations of the South Main Line when adopting single stage pumps.
