A2F23W3Z1定量柱塞泵

柱(zhu)塞泵是液(ye)壓系統的一個重要(yao)裝置。它依靠柱(zhu)塞在缸體中往復運動，使密封工作容腔(qiang)的容積發生變(bian)化來實現吸油(you)、壓油(you)。柱(zhu)塞泵具(ju)有(you)額定壓力高、結構緊湊、效率高和流量調節方(fang)便等優(you)點。

柱(zhu)塞泵被廣泛應用于高壓(ya)(ya)、大流(liu)量和(he)流(liu)量需要調節的場合，諸如(ru)液壓(ya)(ya)機、工(gong)程(cheng)機械和(he)船舶中(zhong)。

柱(zhu)(zhu)塞(sai)泵(beng)柱(zhu)(zhu)塞(sai)往(wang)復運(yun)動(dong)總行(xing)程L是不(bu)(bu)變(bian)(bian)(bian)的(de)(de)，由凸(tu)輪(lun)的(de)(de)升程決(jue)定。柱(zhu)(zhu)塞(sai)每循環的(de)(de)供(gong)油(you)(you)(you)(you)量大小取決(jue)于供(gong)油(you)(you)(you)(you)行(xing)程,供(gong)油(you)(you)(you)(you)行(xing)程不(bu)(bu)受凸(tu)輪(lun)軸控制是可(ke)變(bian)(bian)(bian)的(de)(de)。供(gong)油(you)(you)(you)(you)開始時(shi)刻(ke)(ke)不(bu)(bu)隨供(gong)油(you)(you)(you)(you)行(xing)程的(de)(de)變(bian)(bian)(bian)化而(er)變(bian)(bian)(bian)化。轉動(dong)柱(zhu)(zhu)塞(sai)可(ke)改變(bian)(bian)(bian)供(gong)油(you)(you)(you)(you)終(zhong)了時(shi)刻(ke)(ke)，從而(er)改變(bian)(bian)(bian)供(gong)油(you)(you)(you)(you)量。柱(zhu)(zhu)塞(sai)泵(beng)工作(zuo)時(shi)，在噴油(you)(you)(you)(you)泵(beng)凸(tu)輪(lun)軸上的(de)(de)凸(tu)輪(lun)與柱(zhu)(zhu)塞(sai)彈簧的(de)(de)作(zuo)用下，迫使柱(zhu)(zhu)塞(sai)作(zuo)上、下往(wang)復運(yun)動(dong)，從而(er)完(wan)成泵(beng)油(you)(you)(you)(you)任務，泵(beng)油(you)(you)(you)(you)過程可(ke)分(fen)為以下兩個(ge)階段。
