用正交设计法通过模拟试验对旋流自吸泵泵体结构参数进行了优化设计,设计了一个4因素3水平的正交方案,研究了泵体各几何参数对旋流自吸泵性能的影响.通过分析性能曲线对比图,找到了对于各个性能的最优方案.并通过对数值计算的数据进行极差分析,获得了各几何参数影响4个性能的主次顺序.通过对数据结果进行综合平衡分析和比较,得出了最优的参数组合.得出的最优参数组合不在原有设计方案中,因此根据分析结果对模型泵进行了再设计.将再设计方案与原有方案的性能作了对比,并判断其为最优方案.本模拟结果对旋流自吸泵性能优化设计有一定的参考价值.

Using orthogonal design, optimization design of rotational flow self-priming pump body structural parameter was done through simulation. Orthogonal scheme of four factors and three levels was designed, the influence of geometrical parameters on the characteristics was studied, and optimal scheme of the characteristics was found by analyzing the contrast of performance curves. The influence orders of geometrical parameters to the four characteristics were obtained by using range analysis. The optimization parameter combination was obtained by comprehensive balance analysis and comparison to the data result. For the optimization parameter combination is not in the original design schemes, the redesign was made based on the analyzed result. The performances between the additional scheme and original schemes were contrasted, and the optimal scheme was determined. The results are instructive to the optimization design of rotational flow self-priming pump.
