油泵的工作原理油泵是液压系统中一个主要组成部分。它将原动机带动它工作时输入的机械能转换为流动油压的压力能,供给系统压力油,是液压系统工作时动力的来源。在第一讲中已简单提到,油泵是利用封闭容器内容积的变化吸油和输油的。下面再以图2—1所示的单活塞泵工 How the pump works The pump is a major part of the hydraulic system. It will be the prime mover to bring it to work when the input mechanical energy is converted to flow pressure pressure energy supply system pressure oil is the source of power when the hydraulic system work. As mentioned briefly in the first lecture, the oil pump uses the change of volume in a closed container to pick up and deliver oil. The following single piston pump shown in Figure 2-1
