液压系统结构

液压系统由信号控制和液压动力两部分组成，信号控制部分用于驱动液压动力部分中的控制阀动作。

液压动力部分采用回路图方式表示，以表明不同功能元件之间的相互关系。液压源含有液压泵、电动机和液压辅助元件；液压控制部分含有各种控制阀，其用于控制工作油液的流量、压力和方向；执行部分含有液压缸或液压马达，其可按实际要求来选择。

泵油过程可分为以下两个阶段。

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。

液压泵过度发热有两个原因：一是机械摩擦生热。柱塞泵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；长期负荷过大导致卸荷阀频繁开启，油缸或阀有内泄（阀内部磨损，缸密封不好）；阀或管道有堵塞现象。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。 

液压泵转速高，排油压力高，工作环境恶劣，油液污染、油液选用不合规定或油液过少，都可造成泵损、泄漏。泵内泄漏可使其功率损失加大，磨损严重。油液中侵入空气后易于压缩，可造成泵干磨。液压泵内长时间的泄漏、干磨或压缩厉害， 必然发热，引起油液升温，造成系统发热。

排量是指泵（或马达）每转一星期，由密封容腔几何标准改动而得的排出（或输入）液体的体积，常用单位是ml/r（毫升/转）。排量可以通过调度发作改动的成为变量泵（或变量马达），排量不能改动的成为定量泵（或定量马达）。

实习流量是指泵（或马达）工作时出口处（或进口处）的流量。由于泵本身存在内泄露，其实习流量小于理论流量。由于马达本身也存在内泄露，要实现****转速，为赔偿泄露量，其输入实习流量大于理论流量。

具有相应的配流安排。将吸液箱和排液箱离隔，保证液压泵有规矩地连续吸排液体凸轮由电动机股动旋转。当凸轮推进柱塞向上运动时，柱塞和缸体构成的密封体积减小，油液从密封体积中挤出，经单向阀排到需求的本地去。当凸轮旋转至曲线的下降部位时，弹簧迫使柱塞向下，构成一定真空度，油箱中的油液在大气压力的作用下进入密封容积。凸轮使柱塞不断地升降，密封容积周期性地减小和加大，泵就不断吸油和排油。
