摘　　要：建立以低比速离心泵效率最高、汽蚀余量最小、理论扬程最大的多目标数学优化模型,对与曲线驼峰相关的参数进行约束设置,提出利用遗传算法求解低比速离心泵的多目标数学优化模型的方法。仿真结果表明,与传统方法设计出来的离心泵进行比较,不考虑扬程离心泵的优化其扬程往往达不到设计的要求,而考虑扬程的优化则解决这一问题,为低比转速离心泵的设计提供参考依据。Establishing multi-objective optimization mathematical model of low specific speed centrifugal pump highest efficiency, NPSH minimum and maximum theoretical head. Setting parameters related constraints for the curve hump, proposing the method that solving multi-objective optimization mathematical model low specific speed centrifugal pump with genetic algorithms. Simulation results show that compare with the traditional method of centrifugal pumps design, considering of the optimizing theoretical head is better, which provides a reference to a low specific speed centrifugal pump the design.
