摘　　要：针对双作用叶片泵流量脉动较大的问题,设计一种新型复合双作用径向叶片泵。复合双作用叶片泵的两对定子、转子完全相同且对称安装,其流量为两部分流量耦合。通过改变两定子配合角度以改变出口流量,从而降低瞬时流量的脉动性。对两定子配合角度分别为0°、45°、90°进行数值分析,研究表明所设计的复合泵能有效提高流量,瞬时流量脉动性得到改善。In view of the large flow pulsation of double-acting vane pumps,a new type of compound double-acting radial vane pump is designed.The two pairs of stators and rotors of the compound double-acting vane pump are completely identical and installed symmetrically,and the flow is two-part flow coupling.By changing the matching angle of the two stators,the outlet flow rate is changed to reduce the pulsation of the instantaneous flow rate.The research carries out a numerical analysis of the matching angles of the two stators at 0°,45°and 90°respectively.It is shown that the designed compound pump effectively increases the flow rate,and the instantaneous flow rate is improved by the pulsation.
