摘　　要：为提高摆线转子泵的出口压力,设计一种串联双级复合摆线转子泵,基于泛摆线形成原理和内转子摆线齿形曲线参数方程,完成内外转子的三维参数化建模;研究复合摆线转子泵压力与流量的特性。结果表明与单级摆线泵比较,复合双级摆线转子泵的出口压力有了较大提高,且流量的脉动性得到有效改善。In order to improve the outlet pressure of the gerotor pump, a series two-stage composite gerotor pump is designed, based on the principle of pan-swing line formation and the parameter equation of the internal rotor swing profile curve, and the three-dimensional parameter modeling of the internal and external rotor is completed.The characteristics of the pressure and flow of the gerotor pump of the composite swing line are studied.The results show that compared with the single-stage swing pump, the outlet pressure of the composite two-stage gerotor pump has been greatly improved, and the pulsation of the flow rate has been effectively improved.
