机械分类

喷油型

喷油泵主要用在的汽车柴油机上，喷油泵总成通常是由喷油泵、调速器等部件安装在一起组成的一个整体。其中调速器是保障柴油机的低速运转和对高转速的限制，确保喷射量与转速之间保持一定关系的部件。而喷油泵则是柴油机重要的部件，被视为柴油发动机的“心脏”部件，它一旦出问题会使整个柴油机工作失常。

自吸油型

自吸油泵 启动前先在泵壳内灌满水（或泵壳内自身存有水）。启动后叶轮高速旋转使叶轮槽道中的水流向涡壳，这时入口形成真空，使进水逆止门打开，吸入管内的空气进入泵内，并经叶轮槽道到达外缘。然后与右回水孔流来的水汇合，顺着蜗壳流动。由于液体在蜗壳内不断冲击叶栅，就同空气强烈搅拌混合，生成气水混合物，并不断地流动致使气水不能分离。混合物在蜗壳出口被隔舌剥离，沿短管进入分离室。在分离室内空气被分离出来，由出口管排掉，而水仍经左右回水孔流向叶轮外缘，并与吸入管空气相混合。如此反复循环，逐渐将吸入管路中的空气排尽，使水进入泵内，完成自吸过程。

进油过程

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

回油过程

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，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。

柱塞泵以一个柱塞为原理介绍，一个柱塞泵上有两个单向阀，并且方向相反，柱塞向一个方向运动时缸内出现负压，这时一个单向阀打开液体被吸入缸内，柱塞向另一个方向运动时，将液体压缩后另一个单向阀被打开，被吸入缸内的液体被排出。这种工作方式连续运动后就形成了连续供油。

液压泵压力的调整

系统压力检测（二次溢流阀设定压力）

1、关闭挖掘机的发动机，放掉油箱内的空气，关闭高、低压截止阀，然后拆卸高压端 H1A 软管（小臂上截止阀钢管 P1A 与连接的软管）。注意：准备盛液压油的容器和做好防尘工作！

2、确认管路上的管接头大小，然后将测压表和管接头连接好。在高压截止阀钢管前端接头处接上测压表具（表面较大量程大于 25MPa）。打开高压端截止阀（再次确认低压截至阀处于关闭状态）。启动挖掘机，并打****阀，踩下脚踏阀，即可测出系统压力值。如测量压力值达不到标准，应该及时调整。

3、重新调整二次溢流阀的设定压力（手柄顺时针旋转为加大溢流压力），使其压力达到标准值，然后紧固溢流阀上的锁紧螺母，以防止螺母松动造成设置压力的变化。

4、测试和设置压力完毕后，关闭挖掘机的发动机，放掉油箱内的空气。将高压端截止阀关闭，拆下测压表具，将和挖机用 H1A 软管连接，形成闭环。打开高、低压端的截止阀并将截至阀锁紧，进入工作状态。
