    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。

    液压泵是液压系统的动力元件,其功用是给液压系统提供压力油,从能量转换角度讲,它将是原动机(如发动机)输出的机械能转换为便于输送的液体的压力能。液压马达则属于执行元件,它能将输入液体的压力能转换为输出轴转动的机械能,用来拖动负载做功。根据结构形式,液压泵与液压马达具体可分为齿轮式、叶片式、柱塞式等类型。
    1.液压泵压力
    液压泵工作压力是指泵(或马达)在实际工作时输出(或输入)油液的压力,由外负载决定。
    额定压力是指在正常工作条件下,按试验标准规定能连续运转的最高压力。其大小受寿命的限制,若超过额定压力工作,泵(或马达)的使用寿命将会比设计的寿命短。当工作压力大于额定压力时称超载。
    2.转速
    工作转速是指泵(或马达)在工作时的实际转动速度。
    额定转速是指在额定压力下,能连续长时间正常运转的最高转速。若泵超过额定转速工作将会造成吸油不足,产生振动和大的噪声,零件会遭受气蚀损伤,寿命降低。
    最低稳定转速是指马达正常运转所允许的最低转速。在此转速下,马达不出现爬行现象。
    3.排量、流量
    排量是指泵(或马达)每转一周,由密封容腔几何尺寸变化而得的排出(或输入)液体的体积,常用单位是ml/r(毫升/转)。排量可以通过调节发生变化的成为变量泵(或变量马达),排量不能变化的成为定量泵(或定量马达)。
    实际流量是指泵(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漏,其实际流量小于理论流量。由于马达本身也存在内泄漏,要实现指定转速,为补偿泄漏量,其输入实际流量必须大于理论流量。
    4.效率
    容积效率,对液压泵是指其实际流量与理论流量的比值。对液压马达是指其理论流量与实际流量的比值。
    机械效率,对液压泵是指其理论转矩与实际输入转矩的比值。对液压马达其实际输出的转矩为理论转矩克服摩擦力后的转矩,因此其机械效率为实际输出转矩与理论转矩的比值。
    总效率是指泵(或马达)的输出功率与输入功率的比值。总效率等于容积效率与机械效率的乘积。
