液压泵原理
是为液压传动提供加压液体的一种液压元件，是泵的一种。它的功能是把动力机(如电动机和内燃机等)的机械能转换成液体的压力能。图中为单柱塞泵的工作原理。凸轮由电动机带动旋转。当凸轮推动柱塞向上运动时，柱塞和缸体形成的密封体积减小，油液从密封体积中挤出，经单向阀排到需要的地方去。当凸轮旋转至曲线的下降部位时，弹簧迫使柱塞向下，形成一定真空度，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增 大，泵就不断吸油和排油。

齿轮泵工作时，主动轮随电动机一起旋转并带动从动轮跟着旋转。当吸入室一侧的啮合齿逐渐分开时，吸入室容积增大，压力降低，便将吸人管中的液体吸入泵内；吸入液体分两路在齿槽内被齿轮推送到排出室。液体进入排出室后，由于两个齿轮的轮齿不断啮合，便液体受挤压而从排出室进入排出管中。主动齿轮和从动齿轮不停地旋转，泵就能连续不断地吸入和排出液体。
泵体上装有安全阀，当排出压力超过规定压力时，输送液体可以自动顶开安全阀，使高压液体返回吸入管。

柱塞头部圆柱面上切有斜槽，并通过径向孔、轴向孔与顶部相通，其目的是改变循环供油量；柱塞套上制有进、回油孔，均与泵上体内低压油腔相通，柱塞套装入泵上体后，应用定位螺钉定位。
柱塞头部斜槽的位置不同，改变供油量的方法也不同。
出油阀和出油阀座也是一对精密偶件，配对研磨后不能互换，其配合间隙为0.01mm 。
