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：

如圖所(suo)示，當液(ye)壓(ya)系統壓(ya)力(li)油(you)進入(ru)(ru)一主(zhu)(zhu)油(you)缸(gang)(gang)(gang)時(shi)，活(huo)塞(sai)(sai)桿(gan)伸出，同時(shi)通(tong)過(guo)密封回(hui)路連(lian)通(tong)管的(de)(de)壓(ya)力(li)油(you)使(shi)另(ling)一活(huo)塞(sai)(sai)桿(gan)回(hui)縮。與(yu)主(zhu)(zhu)油(you)缸(gang)(gang)(gang)活(huo)塞(sai)(sai)桿(gan)相連(lian)的(de)(de)混(hun)(hun)(hun)凝(ning)土(tu)(tu)輸(shu)(shu)送(song)(song)(song)(song)活(huo)塞(sai)(sai)回(hui)縮時(shi)在(zai)輸(shu)(shu)送(song)(song)(song)(song)缸(gang)(gang)(gang)內產(chan)生自(zi)吸作(zuo)用(yong)，料(liao)斗中(zhong)的(de)(de)混(hun)(hun)(hun)凝(ning)土(tu)(tu)在(zai)大氣壓(ya)力(li)作(zuo)用(yong)和攪拌葉片的(de)(de)助(zhu)推(tui)作(zuo)用(yong)下通(tong)過(guo)滑閥(fa)吸入(ru)(ru)口被吸入(ru)(ru)輸(shu)(shu)送(song)(song)(song)(song)缸(gang)(gang)(gang)。同時(shi)，另(ling)一主(zhu)(zhu)油(you)缸(gang)(gang)(gang)在(zai)油(you)壓(ya)的(de)(de)作(zuo)用(yong)下，推(tui)動主(zhu)(zhu)油(you)缸(gang)(gang)(gang)的(de)(de)活(huo)塞(sai)(sai)桿(gan)伸出并同時(shi)推(tui)動混(hun)(hun)(hun)凝(ning)土(tu)(tu)活(huo)塞(sai)(sai)壓(ya)出輸(shu)(shu)送(song)(song)(song)(song)缸(gang)(gang)(gang)中(zhong)的(de)(de)混(hun)(hun)(hun)凝(ning)土(tu)(tu)，通(tong)過(guo)滑閥(fa)輸(shu)(shu)送(song)(song)(song)(song)口Y字管進入(ru)(ru)混(hun)(hun)(hun)凝(ning)土(tu)(tu)輸(shu)(shu)送(song)(song)(song)(song)管。動作(zuo)完(wan)成后，系統自(zi)動換(huan)向使(shi)壓(ya)力(li)油(you)進入(ru)(ru)另(ling)一主(zhu)(zhu)油(you)缸(gang)(gang)(gang)，完(wan)成另(ling)一次不(bu)同輸(shu)(shu)送(song)(song)(song)(song)缸(gang)(gang)(gang)的(de)(de)吸、送(song)(song)(song)(song)行程。如此反(fan)復，料(liao)斗里(li)的(de)(de)混(hun)(hun)(hun)凝(ning)土(tu)(tu)就源(yuan)源(yuan)不(bu)斷地被吸入(ru)(ru)和壓(ya)送(song)(song)(song)(song)出輸(shu)(shu)送(song)(song)(song)(song)缸(gang)(gang)(gang)，通(tong)過(guo)Y型(xing)管和出口連(lian)接(jie)的(de)(de)管道到達(da)作(zuo)業點，完(wan)成泵送(song)(song)(song)(song)作(zuo)業。
