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
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。A2F45R6.1B3 A2F45L6.1B3 A2F45W6.1B3
