摘　　要：以深井泵叶片数、出口安放角、出口宽度等7个因素,每个因素取3个水平,按L18(37)正交试验方案,设计了18副叶轮。通过CFD技术对叶轮、导叶在内的两级深井泵的全流场进行了设计工况下的三维数值模拟,获得了18组设计方案的效率、扬程值。通过正交试验法探索了各几何参数对效率、扬程的影响规律,并通过极差分析找到了影响这些性能的主要因素和次要因素,根据优选结果结合内部流场测试及样机试验验证对模型泵提出了进一步优化设计方案。本试验结果对采用叶轮极大扬程设计法的深井泵水力设计具有一定的参考价值。An L18（37） orthogonal experiment was designed with seven factors and three values including blades numbers,outlet angle,outlet width,etc.18 impellers were designed totally.The two stages of whole flow field on deep well pump in the operating point for design was simulated by using CFD.The 18 groups of the design scheme for efficiency and head were obtained.Using Latin square test,the effect of geometrical parameters on efficiency and head were researched.The primary and secondary sequence of the design parameters were acquired by the method of variance analysis.According to the test result and optimization design with experimental research,an optimum program to further design was put forward.The result could be instructive to the design of the deep well pump,which was designed by the impeller head maximum approach.
