        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)变量调节机构螺栓松动,密封破损;(6)铸铁泵壳有砂眼或焊接不良。(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;5.振动和噪声如泵轴和电机轴不同心或顶死,旋转轴的轴承、联轴节损伤,弹性垫破损和装配螺栓松动均会产生噪声。对于高速运转或传输大能量的泵,要定期检查,记录各部件的振幅、频率和噪声。如泵的转动频率与压力阀的固有频率相同时,将会引起共振,可改变泵的转速以消除共。 由于放大器能量不足或零件损坏,含有弹簧的控制活塞的阻尼器效能差,都会造成控制活塞运动不稳定,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。

        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。5.振动和噪声(3)倾斜盘倾角太小,泵的排量少,这需要调节变量活塞,增加斜盘倾角。柱塞泵的维护当凸轮的凸起部分转过去后,在弹簧力的作用下,柱塞向下运动,柱塞上部空间(称为泵油室)产生真空度,当柱塞上端面把柱塞套上的进油孔打开后,充满在油泵上体油道内的柴油经油孔进入泵油室,柱塞运动到下止点,进油结束。进油过程柱塞泵是往复泵的一种,属于体积泵,其柱塞靠泵轴的偏心转动驱动,往复运动,其吸入和排出阀都是单向。 可以通过检查泵体内液压油中混杂的异物判别泵被损坏的部位,(5)变量调节机构螺栓松动,密封破损,2.中位时排油量不为零(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,油箱中液面过低。

        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。(2)泄漏量过大。原因是泵的间隙过大,密封不良造成。如配油盘被金属碎片、铁屑等划伤,端面漏油;变量机构中的单向阀密封面配合不好,泵体和配油盘的支承面有砂眼或研痕等。可以通过检查泵体内液压油中混杂的异物判别泵被损坏的部位。进油过程带滑靴结构的轴向柱塞泵是目前使用广泛的轴向柱塞泵,安放在缸体中的柱塞通过滑靴与斜盘相接触,当传动轴带动缸体旋转时,斜盘将柱塞从缸体中拉出或推回,完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。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。 完成吸排油过程,柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸,排油腔相通,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,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。

        泵体和配油盘的支承面有砂眼或研痕等。可以通过检查泵体内液压油中混杂的异物判别泵被损坏的部位。当凸轮轴转到凸轮的凸起部分顶起滚轮体时,柱塞弹簧被压缩,柱塞向上运动,燃油受压,一部分燃油经油孔流回喷油泵上体油腔。当柱塞顶面遮住套筒上进油孔的上缘时,由于柱塞和套筒的配合间隙很小(0.0015-0.0025mm)使柱塞顶部的泵油室成为一个密封油腔,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。柱塞泵柱塞往复运动总行程L是不变的,由凸轮的升程决定。柱塞每循环的供油量大小取决于供油行程,供油行程不受凸轮轴控制是可。 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。
