        将会引起共振,可改变泵的转速以消除共振。液压泵过度发热有两个原因,一是机械摩擦生热。由于运动表面处于干摩擦或半干摩擦状态,运动部件相互摩擦生热。二是液体摩擦生热。高压油通过各种缝隙泄漏到低压腔,大量的液压能损失转为热能。所以正确选择运动部件之间的间隙、油箱容积和冷却器,可以杜绝泵的过度发热和油温过高的现象。另外,回油过滤器堵塞造成回油背压过高,也会引起油温过高和泵体过热。柱塞泵漏油主要有以下原因:(1)主轴油封损坏或轴有缺陷、划痕;(2)内部泄漏过大,造成油封处压力增大,而将油封损伤或冲出;(3)泄油管过细过长,使密封处漏油;(4)泵的外接油管松动,管接头损伤,密封垫老化或产生裂纹;(5)变量调节机构螺栓。 这需要找出漏气处,紧固,更换密封件,即可提高压力,溢流阀有故障或调整压力低,系统压力也上不去,应重新调整压力或检修溢流阀,如果液压泵的缸体与配流盘产生偏差造成大量泄漏,严重时,缸体可能破裂,则应重新研磨配合面或更换液压泵。

        由于径向柱塞泵属于一种新型的技术含量比较高的泵,随着国产化的不断加快,径向柱塞泵必然会成为柱塞泵应用领域的重要组成部分.回油过程当泵在自吸状态下,若进油管路漏气或系统中液压缸、单向阀、换向阀等有较大的泄漏,均会使压力升不上去。这需要找出漏气处,紧固、更换密封件,即可提高压力。溢流阀有故障或调整压力低,系统压力也上不去,应重新调整压力或检修溢流阀。如果液压泵的缸体与配流盘产生偏差造成大量泄漏,严重时,缸体可能破裂,则应重新研磨配合面或更换液压泵。液压泵过度发热有两个原因,一是机械摩擦生热。由于运动表面处于干摩擦或半干摩擦状态,运动部件相互摩擦生热。二是液体摩擦生热。高压油通过各种缝隙泄漏到低。

        如不具备检测条件,也应在系统中反复调试,使其能正常工作。变量柱塞泵的压力油经泵体、泵壳变量壳体中的通油孔通过单向阀进入变量壳体的下腔,当拉杆向下运动时,推动伺服活塞向下移动,伺服阀的上阀口打开,变量壳体下腔的压力油经变量活塞中的通油孔进入变量壳体上腔,由于上腔面积大于下腔,液压力推动活塞向下运动,带动销轴使变量头绕钢球中心旋转,改变变量头的倾斜角(增大),柱塞泵的流量随之增大。反之拉杆向上运动,变量头的倾斜角向相反方向变化,泵的流量也随之变化。当倾斜角度变至零以后,则变量头向负偏角方向变化,液流产生换向,泵的进出油口变换。(1)吸入量不足。原因是吸油管路上的阻力过大或补油量不足。如泵的转速过大。 柱塞继续上升,泵油室内的油压迅速升高,泵油压力>出油阀弹簧力+高压油管剩余压力时,推开出油阀,高压柴油经出油阀进入高压油管,通过喷油器喷入燃烧室,(1)吸入量不足,原因是吸油管路上的阻力过大或补油量不足。V50A3RX-20泵
