不锈钢冲压多级泵已成为民用多级泵的主流。结合冲焊泵的工艺特点，对冲焊泵液压件的设计进行了研究。以叶片进口角、叶轮外径、导叶叶片数等7个因素3个值进行L18（37）正交试验，共设计了18个方案。采用CFD方法对不锈钢冲压多级泵在设计工况下的两级全流场进行了数值模拟。根据试验结果和优化设计，结合试验研究，得出了影响水力性能的主要参数的变化趋势。优化后的模型泵经试制和试验，效率达到61.36%，单扬程大于4.8m。与标准效率53%相比，不锈钢冲压泵的设计是成功的。研究结果对采用叶轮扬程最大值法设计不锈钢冲压多级泵具有指导意义。
Stainless steel stamping multistage pump has become the mainstream of civil multi-stage pump. Combined with the technological features of stamping and welding pump, the studies of design for hydraulic parts of pump were come out. An L18（3 7 ）orthogonal experiment was designed with seven factors and three values including blade inlet angle, impeller outer diameter, guide vane blade number, etc. 18 plans were designed. The two stage of whole flow field on stainless steel stamping multistage pump at design point for design was simulated by CFD. According to the test result and optimization design with experimental research, the trends of main parameters which affect hydraulic performance were got. After being manufactured and tested, the efficiency of the optimal model pump reaches 61.36% and the single head is more than 4.8 m. Compared with the standard efficiency of 53%, the design of the stainless steel stamping pump is successful. The result would be instructive to the design of Stainless steel stamping multistage pump designed by the impeller head maximum approach.
