        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。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变的。供油开始时刻不随供油行程的变化而变化。转动柱塞可改变供油终了时刻,从而改变供油量。柱塞泵工作时,在喷油泵凸轮轴上的凸轮与柱塞弹簧的作用下,迫使柱塞作上、下往复运动,从而完成泵油任务,泵油过程可分为以下两个阶段。6.液压泵过热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。 与输入转矩似成正比,输出压力异常有两种故障,(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。

        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振。柱塞泵分为轴向柱塞泵和径向柱塞泵两种代表性的结构形式;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.泵的输出压力是由负载决定的,与输入转矩似成正比。输出压力异常有两种故障。(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。如泵轴和电机轴不同心或顶死,旋转轴的轴承、联轴节。 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,4.输出压力异常柱塞向上供油,当上行到柱塞上的斜槽(停供边)与套筒上的回油孔相通时。

        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。7.漏油(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。柱塞泵漏油主要有以下原因:(6)铸铁泵壳有砂眼或焊接不良。(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,进油管漏气,滤油器堵塞等。回油过程进油管道太细、进油滤油器通流能力过小或堵塞、进油管吸入空气、油液豁度过高、油面过低吸油不足和高压管道中产生液。 这种工作方式连续运动后就形成了连续供油,(2)输出压力过高柱塞泵的维护7.漏油振动和噪声是同时出现的,它们不仅对机器的操作者造成危害,也对环境造成污染,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。
