摘　　要：以南水北调东线淮安三站后置灯泡贯流泵装置为例,采用ANSYS-CFX数值模拟方法计算并分析了不同的叶片位置对泵装置性能的影响。结果表明,不同的扩散导叶体叶片位置对扩散导叶体的压能恢复系数、水头损失以及内、外特性均有明显影响,且叶片位置与叶轮之间的距离存在着最优搭配。Taking bulb tubular pumping system of Huai＇an Third Pumping Station in East Routes of South-to North Water Diversion Project as the research object, numerical simulation with ANSYS-CFX was used to calculate and analyze the influence of different blade position on the performance of the pump device. Results show the pressure energy recover y coefficient, head loss, inner and external characteristic are obviously influenced by the position of the diffuser vane. The position of the blade and the distance between the impeller exist the best collocation.
