機械分類 柱(zhu)塞(sai)泵一(yi)般分為單柱(zhu)塞(sai)泵、臥(wo)式柱(zhu)塞(sai)泵、軸向(xiang)柱(zhu)塞(sai)泵和徑向(xiang)柱(zhu)塞(sai)泵。 單柱塞泵 結構組成主要有偏(pian)心(xin)輪、柱塞、彈簧、缸體、兩個單(dan)向閥。柱塞與缸體孔之(zhi)間形成密閉(bi)容(rong)積。偏(pian)心(xin)輪旋轉一(yi)轉，柱塞上(shang)下往(wang)復運(yun)動一(yi)次，向下運(yun)動吸油(you)，向上(shang)運(yun)動排(pai)油(you)。泵每轉一(yi)轉排(pai)出的油(you)液(ye)體積稱(cheng)為(wei)排(pai)量(liang)，排(pai)量(liang)只與泵的結構參數有關。 臥式柱塞泵 臥式(shi)(shi)柱塞(sai)(sai)泵(beng)是由幾個柱塞(sai)(sai)（一般為3個或6個）并列安裝，用1根曲軸通過連桿滑塊(kuai)或由偏心軸直接推動(dong)柱塞(sai)(sai)做往復運動(dong)，實現吸、排液(ye)體的液(ye)壓泵(beng)。它們也都采用閥式(shi)(shi)配流裝置，而且(qie)大(da)多為定量泵(beng)。煤礦液(ye)壓支架(jia)系(xi)統(tong)中的乳化液(ye)泵(beng)一般都是臥式(shi)(shi)柱塞(sai)(sai)泵(beng)。 乳(ru)化液泵(beng)用于采(cai)煤(mei)工作面(mian)，為液壓支(zhi)架提供乳(ru)化液，工作原理靠曲軸的旋(xuan)轉帶動(dong)活塞(sai)做往(wang)復運動(dong)，實現吸液和排液。 軸向式 軸(zhou)向柱(zhu)塞(sai)(sai)(sai)泵（英文名：Piston pump）是活塞(sai)(sai)(sai)或柱(zhu)塞(sai)(sai)(sai)的(de)(de)往復運動(dong)方向與(yu)缸體中心(xin)軸(zhou)平行的(de)(de)柱(zhu)塞(sai)(sai)(sai)泵。軸(zhou)向柱(zhu)塞(sai)(sai)(sai)泵利用與(yu)傳動(dong)軸(zhou)平行的(de)(de)柱(zhu)塞(sai)(sai)(sai)在(zai)柱(zhu)塞(sai)(sai)(sai)孔(kong)內往復運動(dong)所產(chan)生的(de)(de)容積變(bian)化來進行工作的(de)(de)。由于柱(zhu)塞(sai)(sai)(sai)和柱(zhu)塞(sai)(sai)(sai)孔(kong)都是圓形零(ling)件，加工時可(ke)以達到(dao)很(hen)高(gao)的(de)(de)精度配(pei)合，因此容積效率高(gao)。 直軸斜盤式 直軸斜(xie)盤(pan)式柱塞泵分(fen)為壓(ya)(ya)(ya)(ya)(ya)力(li)供油(you)(you)(you)型(xing)和自(zi)吸油(you)(you)(you)型(xing)兩(liang)種(zhong)。壓(ya)(ya)(ya)(ya)(ya)力(li)供油(you)(you)(you)型(xing)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵大(da)都(dou)是采用(yong)有(you)氣壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)油(you)(you)(you)箱(xiang)(xiang)，靠(kao)氣壓(ya)(ya)(ya)(ya)(ya)供油(you)(you)(you)的(de)(de)(de)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang)，在每次啟(qi)動(dong)機(ji)器之后(hou)，必須(xu)等液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)漬箱(xiang)(xiang)達到(dao)使(shi)用(yong)氣壓(ya)(ya)(ya)(ya)(ya)后(hou)，才能(neng)操(cao)作(zuo)機(ji)械。如液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang)的(de)(de)(de)氣壓(ya)(ya)(ya)(ya)(ya)不足(zu)時就啟(qi)動(dong)機(ji)器，會對液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵內的(de)(de)(de)與滑靴造成拉脫現象(xiang)，出(chu)會造成泵體(ti)內回程板與壓(ya)(ya)(ya)(ya)(ya)板的(de)(de)(de)非正常磨損(sun)。 徑向式 徑(jing)向(xiang)(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)可分為閥配(pei)流與軸(zhou)配(pei)流兩大類。閥配(pei)流徑(jing)向(xiang)(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)存(cun)在(zai)故(gu)障(zhang)率(lv)高、效率(lv)低等缺點。上(shang)70、80年代發展(zhan)的(de)(de)(de)軸(zhou)配(pei)流徑(jing)向(xiang)(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)克服了(le)閥配(pei)流徑(jing)向(xiang)(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)的(de)(de)(de)不(bu)足。由于徑(jing)向(xiang)(xiang)(xiang)(xiang)泵(beng)(beng)(beng)結構上(shang)的(de)(de)(de)特點，固定了(le)軸(zhou)配(pei)流徑(jing)向(xiang)(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)比軸(zhou)向(xiang)(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)耐沖(chong)擊、壽命長、控制精度(du)高。變(bian)量(liang)行(xing)程(cheng)短泵(beng)(beng)(beng)的(de)(de)(de)變(bian)量(liang)是在(zai)變(bian)量(liang)柱塞(sai)(sai)和限位柱塞(sai)(sai)作用下，改(gai)變(bian)定子的(de)(de)(de)偏心距實現的(de)(de)(de)，而定于的(de)(de)(de)zui大偏心距為 5—9mm（根據排量(liang)大小不(bu)同），變(bian)量(liang)行(xing)程(cheng)很短。且變(bian)量(liang)機構設計(ji)為高壓操縱，由控制閥進行(xing)控制。故(gu)該泵(beng)(beng)(beng)的(de)(de)(de)響應速(su)度(du)快(kuai)。徑(jing)向(xiang)(xiang)(xiang)(xiang)結構設計(ji)克服了(le)如軸(zhou)向(xiang)(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)滑靴偏磨(mo)的(de)(de)(de)問題。使(shi)其抗(kang)沖(chong)擊能力大幅度(du)提高。 液壓式 液(ye)(ye)壓柱(zhu)塞泵(beng)(beng)靠氣(qi)壓供(gong)油(you)(you)(you)的(de)(de)液(ye)(ye)壓油(you)(you)(you)箱，在每次啟動機(ji)器后(hou)，必須等液(ye)(ye)壓油(you)(you)(you)箱達到使用氣(qi)壓后(hou)，才能(neng)操作機(ji)械。直軸斜盤式柱(zhu)塞泵(beng)(beng)分為壓力(li)(li)供(gong)油(you)(you)(you)型(xing)(xing)的(de)(de)自(zi)吸(xi)油(you)(you)(you)型(xing)(xing)兩(liang)種。壓力(li)(li)供(gong)油(you)(you)(you)型(xing)(xing)液(ye)(ye)壓泵(beng)(beng)大都采用有(you)氣(qi)壓的(de)(de)油(you)(you)(you)箱，也有(you)液(ye)(ye)壓泵(beng)(beng)本(ben)身(shen)帶有(you)補油(you)(you)(you)分泵(beng)(beng)向(xiang)液(ye)(ye)壓泵(beng)(beng)進油(you)(you)(you)口提供(gong)壓力(li)(li)油(you)(you)(you)的(de)(de)。自(zi)吸(xi)油(you)(you)(you)型(xing)(xing)液(ye)(ye)壓泵(beng)(beng)的(de)(de)自(zi)吸(xi)油(you)(you)(you)能(neng)力(li)(li)很強，無(wu)需(xu)外力(li)(li)供(gong)油(you)(you)(you)。
