摘要

针对摆线转子泵理论流量计算复杂,经验公式精确度较低的问题,基于Creo/parametric将参数化建模技术引入到摆线泵流量计算中,建立了摆线泵容腔端面的参数化模型,通过建立测量特征计算出了泵的排量,通过与理论排量对比,验证了参数化模型精度高于经验公式精度,根据积分原理,建立了转子啮合运动中,容腔端面变化沿轴向的累积模型,通过敏感度分析建立了容腔端面对转子转角的变化率曲线,进而得到了泵的流量曲线,并通过和理论流量曲线对比,验证了曲线的正确性。

Abstract

To solve the problems that theoretical flow calculation of cycloidal rotor pump is complicated and the accuracy of empirical formula is low,the parametric modeling technique is introduced into the calculation of the flow rate of cycloidal pump based on Creo / parametric. The parametric model of the end face of the pump chamber is established. And the displacement of the pump is calculated by establishing the measurement characteristic. By comparison with theoretical displacement,the conclusion that the accuracy of the parametric model is higher than the empirical formula is verified. According to the integral principle,the accumulation model of the change of the cavity surface in the meshing movement is established. By sensitivity analysis,The curve of the cavity end face change rate to the rotor movement angle is established. And the flow curve is obtained. By comparison with theoretical flow curve,the correctness of the curve is verified.
