混凝土輸送泵采用電動機或柴油機驅動泵送系統，通過液壓系統恒功率控制自動調節混凝土輸送泵的輸送量，也可用手動控制來選擇混凝土輸送量。混凝土泵泵送系統主要由料斗、攪拌機構、混凝土分配閥、混凝土輸送缸、洗滌室以及主油缸等構成。

工作原理：

如(ru)圖所示，當液(ye)壓(ya)(ya)系統(tong)壓(ya)(ya)力(li)油(you)進入一主(zhu)油(you)缸(gang)(gang)時(shi)(shi)，活(huo)(huo)塞桿伸出(chu)(chu)(chu)，同時(shi)(shi)通過密封(feng)回(hui)路連(lian)通管的(de)(de)壓(ya)(ya)力(li)油(you)使另(ling)一活(huo)(huo)塞桿回(hui)縮。與主(zhu)油(you)缸(gang)(gang)活(huo)(huo)塞桿相(xiang)連(lian)的(de)(de)混(hun)(hun)(hun)(hun)凝(ning)(ning)土(tu)輸(shu)送(song)(song)(song)活(huo)(huo)塞回(hui)縮時(shi)(shi)在輸(shu)送(song)(song)(song)缸(gang)(gang)內產生自(zi)(zi)吸(xi)(xi)作(zuo)(zuo)(zuo)用(yong)(yong)，料斗中的(de)(de)混(hun)(hun)(hun)(hun)凝(ning)(ning)土(tu)在大(da)氣壓(ya)(ya)力(li)作(zuo)(zuo)(zuo)用(yong)(yong)和攪拌葉片的(de)(de)助推作(zuo)(zuo)(zuo)用(yong)(yong)下通過滑(hua)(hua)閥(fa)吸(xi)(xi)入口被吸(xi)(xi)入輸(shu)送(song)(song)(song)缸(gang)(gang)。同時(shi)(shi)，另(ling)一主(zhu)油(you)缸(gang)(gang)在油(you)壓(ya)(ya)的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)下，推動(dong)主(zhu)油(you)缸(gang)(gang)的(de)(de)活(huo)(huo)塞桿伸出(chu)(chu)(chu)并同時(shi)(shi)推動(dong)混(hun)(hun)(hun)(hun)凝(ning)(ning)土(tu)活(huo)(huo)塞壓(ya)(ya)出(chu)(chu)(chu)輸(shu)送(song)(song)(song)缸(gang)(gang)中的(de)(de)混(hun)(hun)(hun)(hun)凝(ning)(ning)土(tu)，通過滑(hua)(hua)閥(fa)輸(shu)送(song)(song)(song)口Y字管進入混(hun)(hun)(hun)(hun)凝(ning)(ning)土(tu)輸(shu)送(song)(song)(song)管。動(dong)作(zuo)(zuo)(zuo)完成后，系統(tong)自(zi)(zi)動(dong)換向(xiang)使壓(ya)(ya)力(li)油(you)進入另(ling)一主(zhu)油(you)缸(gang)(gang)，完成另(ling)一次不(bu)同輸(shu)送(song)(song)(song)缸(gang)(gang)的(de)(de)吸(xi)(xi)、送(song)(song)(song)行程(cheng)。如(ru)此反復(fu)，料斗里的(de)(de)混(hun)(hun)(hun)(hun)凝(ning)(ning)土(tu)就(jiu)源源不(bu)斷地被吸(xi)(xi)入和壓(ya)(ya)送(song)(song)(song)出(chu)(chu)(chu)輸(shu)送(song)(song)(song)缸(gang)(gang)，通過Y型管和出(chu)(chu)(chu)口連(lian)接的(de)(de)管道到(dao)達作(zuo)(zuo)(zuo)業點，完成泵送(song)(song)(song)作(zuo)(zuo)(zuo)業。
