双作用叶片泵的定子,属于平面定子,定子表面曲线为平面内曲线。 一、定子曲线对叶片泵性能的影响 叶片泵的主要性能指标有流量、压力、转速、效率、噪音等,定子内表面曲线(以下简称定子曲线)在很大程度上决定着叶片泵的性能,如流量均匀性、吸入汽蚀性、叶片径向运动平稳性、有关相对运动表面的磨损及噪音等。 双作用叶片泵的定子曲线,一般都是由四段与转子同心且为轴对称园弧(两段大半径、两段小半径)的工作曲线和四段中 Double-acting vane pump stator, belonging to the plane stator, the stator surface curve for the plane curve. First, the stator curve of the vane pump performance Vane pump performance indicators are flow, pressure, speed, efficiency, noise, the stator inner surface curve (hereinafter referred to as the stator curve) to a large extent determine the vane pump performance, Such as flow uniformity, inhalation cavitation, smooth blade radial movement, the relative movement of the surface wear and noise. Double-acting vane pump stator curve, usually by four sections concentric with the rotor and axisymmetric Park arc (two large radius, two small radius) of the working curve and four sections
