柱塞泵一般分为单柱塞泵、卧式柱塞泵、轴向柱塞泵和径向柱塞泵。
单柱塞泵
结构组成主要有偏心轮、柱塞、弹簧、缸体、两个单向阀。柱塞与缸体孔之间形成密闭容积。偏心轮旋转一转，柱塞上下往复运动一次，向下运动吸油，向上运动排油。泵每转一转排出的油液体积称为排量，排量只与泵的结构参数有关。
卧式柱塞泵
卧式柱塞泵是由几个柱塞（一般为3个或6个）并列安装，用1根曲轴通过连杆滑块或由偏心轴直接推动柱塞做往复运动，实现吸、排液体的液压泵。它们也都采用阀式配流装置，而且大多为定量泵。煤矿液压支架系统中的乳化液泵一般都是卧式柱塞泵。
乳化液泵用于采煤工作面，为液压支架提供乳化液，工作原理靠曲轴的旋转带动活塞做往复运动，实现吸液和排液。
轴向式

轴向柱塞泵（英文名：Piston pump）是活塞或柱塞的往复运动方向与缸体中心轴平行的柱塞泵。轴向柱塞泵利用与传动轴平行的柱塞在柱塞孔内往复运动所产生的容积变化来进行工作的。由于柱塞和柱塞孔都是圆形零件，加工时可以达到很高的精度配合，因此容积效率高
直轴斜盘式

直轴斜盘式柱塞泵分为压力供油型和自吸油型两种。压力供油型液压泵大都是采用有气压的油箱，靠气压供油的液压油箱，在每次启动机器之后，必须等液压渍箱达到使用气压后，才能操作机械。如液压油箱的气压不足时就启动机器，会对液压泵内的与滑靴造成拉脱现象，出会造成泵体内回程板与压板的非正常磨损。
径向式

径向柱塞泵可分为阀配流与轴配流两大类。阀配流径向柱塞泵存在故障率高、效率

液压泵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。影响液压泵的使用寿命因素很多，除了泵自身设计、制造因素外和一些与泵使用相关元（如联轴器、滤油器等）的选用、试车运行过程中的操作等也有关。

常用液压泵的种类：
1、按流量是否可调节可分为：变量泵和定量泵。输出流量可以根据需要来调节的称为变量泵，流量不能调节的称为定量泵。
2、按液压系统中常用的泵结构分为：齿轮泵、叶片泵和柱塞泵3种。
齿轮泵：体积较小，结构较简单，对油的清洁度要求不严，价格较便宜；但泵轴受不平衡力，磨损严重，泄漏较大。
叶片泵：分为双作用叶片泵和单作用叶片泵。这种泵流量均匀、运转平稳、噪音小、作压力和容积效率比齿轮泵高、结构比齿轮泵复杂。

柱塞泵：容积效率高、泄漏小、可在高压下工作、大多用於大功率液压系统；但结构复杂，材料和加工精度要求高、价格贵、对油的清洁度要求高。
一般在齿轮泵和叶片泵不能满足要求时才用柱塞泵。还有一些其他形式的液压泵，如螺杆泵等，但应用不如上述3种普遍。

铝合金制造、强度高、耐腐蚀、重量轻、适合各种环境下作业。
双速特性减少了打压次数，在低压室快速处于负载用功状态，立刻转换成高压，缩短每次作业周期。
配有压力调节阀，可调节控制及设定工作压力。

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。
