摘要: 讨论了一种新型结构的球形叶片液压泵,在详细阐述球形叶片液压泵结构特点的基础上,分析了球形泵的工作原理。通过建立球坐标得出球形叶片液压泵排量的计算公式,采用Pro/E体积测量法验证了理论分析的准确性。进一步分析了该泵的流量输出特性,讨论了斜盘角度、叶片数目等参数对球形叶片液压泵流量脉动的影响。结果表明:叶片数目增加时,叶片泵的流量脉动明显减小。

Abstract: A new type of spherical vane hydraulic pump was discussed herein. Firstly, structural characteristics and working principles of the spherical pumps were discussed. Secondly, a formula for calculating displacement of a hydraulic pump with spherical blades was obtained by spherical coordinates, and the accuracy of theoretical analysis was verified by Pro/E volume measurement method. Finally, flows and output characteristics of the pumps were analyzed. The influences of swash plate angle and the number of blades on flow pulsation with spherical vanes were discussed. The results show that when the number of blades increases, the flow pulsations of the vane pumps decrease obviously.

Key words: hydraulic pump, vane pump, spherical, flow characteristic
