液壓泵的基本工作原理
單柱塞泵的工作原理。凸輪由電動機帶動旋轉。當凸輪推動柱塞向上運動時，柱塞和缸體形成的密封體積減小，油液從密封體積中擠出，經單向閥排到需要的地方去。當凸輪旋轉至曲線的下降部位時，彈簧迫使柱塞向回下，形成一定真空度，油箱中的油液在大氣壓力的
作用下進入密封容積。凸輪使柱塞不斷地升降，密封容積周期性地減小和增大，泵就不斷吸油和排油。
容積式液壓泵的共同工作原理如下:
(1)容積式泵必定有一一個或若干個周期變化的密封容積。密封容積變小使油液被擠出，密封容積變大時形成一定真空度，油液通過吸油管被吸入。密封容積的變換量以及變化頻率決定泵的流量。
( 2)合適的配流裝置。不同形式泵的配流裝置雖然結構形式不同，但所起作用相同，并且在容積式泵中是必不可少的。容積式泵排油的壓力決定于排油管道中油液所受到的負載。
