论文部分内容阅读
自从我刊1977年第三期发表了“凸轮转子型叶片泵和叶片马达的结构与计算”一文以来,引起了很多读者的兴趣,就此种泵是否有流量脉动及如何减少以至消除流量脉动问题进行了研究和讨论。由此,我们在本期发表了这篇文章,针对这种泵采用等加速曲线为凸轮转子轮廓曲线的流量情况,作者进行了分析,得出较精确的流量计算公式和叶片马达的转矩计算公式,供大家参考。从本文的结论来看,采用等加速曲线是不可能完全消除泵的流量脉动的。
Since the publication of “The Structure and Calculation of Cam Rotor Vane Pump and Vane Motor” published in the third issue of 1977, I have drawn many readers’ interest in whether the pump has flow pulsation and how to reduce or eliminate the flow pulsation problem Research and discussion. As a result, we published this article in this issue. In view of this pump using isochronous curves for the flow profile of the cam rotor profile, the author analyzed the more accurate flow calculation formula and the torque calculation of the vane motor Formula, for your reference. From the conclusion of this article, it is impossible to completely eliminate the pulsation of the pump flow by using the equal acceleration curve.
