        变量机构用来改变斜盘的倾角,通过调节斜盘的倾角可改变泵的排量。5.振动和噪声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。(6)铸铁泵壳有砂眼或焊接不良。5.振动和噪声(1)输出压力过低若回路负载持续上升,泵的压力也持续上升,当属正常。若负载一定,泵的压力超过负载所需压力值,则应检查泵以外的液压元件,如方向阀、压力阀、传动装置和回油。 泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通,油压骤然下降,出油阀在弹簧力的作用下迅速关闭,停止供油,此后柱塞还要上行,当凸轮的凸起部分转过去后,在弹簧的作用下,柱塞又下行,此时便开始了下一个循环。

        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,油箱中液面过低,进油管漏气,滤油器堵塞等。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。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。 流量不稳定又往往伴随着压力波动,这类故障一般要拆开液压泵,更换受损零部件,加大阻尼,提高弹簧刚度和控制压力等,变量式轴向柱塞泵的斜盘倾角为零时称为中位,此时泵的输出流量应为零,但有时会出现中位偏离调整机构中点的现象。
