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三个阶段。
结论：通过上述讨论，得出下列结论
① 柱塞往复运动总行程L是不变的，由凸轮的升程决定。
② 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。
③ 供油开始时刻不随供油行程的变化而变化。
④ 转动柱塞可改变供油终了时刻，从而改变供油量。
3. 国产系列柱塞式喷油泵
国产系列柱塞泵主要有A、B、P、Z和Ⅰ、Ⅱ、Ⅲ号等系列。系列化是根据柴油机单缸功率范围对供油量的要求不同，以柱塞行程，泵缸中心距和结构型式为基础，再分别配以不同尺寸的柱塞直径，组成若干种在一个工作循环内供油量不等的喷油泵，以满足各种柴油机的需要。
国产系列喷油泵的工作原理和结构型式基本相同，以A型泵为例介绍柱塞式喷油泵的构造和工作原理。柱塞泵由四大部分组成：分泵、油量调节机构、传动机构和泵体
国产最新智能柱塞泵为微处理器智能控制，液晶屏显示，可与电脑进行通讯，具有工作压力稳定、脉动小、操作方便等特点。广泛用于生化、医药、化工、环保等行业，满足以上行业需要连续恒压、恒流输送液体的要求。

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。
