摘　　要：本文论述了旋喷泵的理论扬程即是叶轮的理论扬程。根据旋喷泵扬程一流量曲线特点，提出了旋喷泵叶轮的优化设计数学模型、叶轮优化设计方法及水力参数的设计原则。依此方法，进行了实例计算，结果表明本方法切实可行。t was concluded that the theoretical ddivery head ofrotary-jet pumps was the theoretical delivery head of theirimpellers. Based on the delivery head-flow quantity curvecharacteristics of rotary-jet pumps,a mathematical modelof optimum design,an optimum design method and designprinciples of hydraulic parameters of the impeller of rotaty-jet pumps were proposed,and practical calculations weregiven. The results showed that the method was feasible.
