機械分類 柱(zhu)塞(sai)泵一(yi)般分為單柱(zhu)塞(sai)泵、臥式柱(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 結構組成主要有偏心輪、柱(zhu)塞(sai)、彈簧(huang)、缸體、兩個(ge)單向閥(fa)。柱(zhu)塞(sai)與(yu)(yu)缸體孔之間形成密(mi)閉容積(ji)(ji)。偏心輪旋(xuan)轉(zhuan)(zhuan)一轉(zhuan)(zhuan)，柱(zhu)塞(sai)上下往(wang)復運動一次，向下運動吸油，向上運動排(pai)油。泵每轉(zhuan)(zhuan)一轉(zhuan)(zhuan)排(pai)出的(de)油液體積(ji)(ji)稱(cheng)為排(pai)量，排(pai)量只與(yu)(yu)泵的(de)結構參數(shu)有關。 臥式柱塞泵 臥(wo)式(shi)柱(zhu)塞(sai)泵(beng)(beng)是由幾個柱(zhu)塞(sai)（一(yi)般(ban)為3個或6個）并列安(an)裝，用(yong)1根曲軸通過連(lian)桿滑塊(kuai)或由偏(pian)心軸直接推動柱(zhu)塞(sai)做(zuo)往復運動，實現(xian)吸、排液(ye)體的(de)液(ye)壓泵(beng)(beng)。它們也都采用(yong)閥(fa)式(shi)配流裝置，而且大多(duo)為定(ding)量泵(beng)(beng)。煤(mei)礦液(ye)壓支(zhi)架系(xi)統(tong)中的(de)乳化液(ye)泵(beng)(beng)一(yi)般(ban)都是臥(wo)式(shi)柱(zhu)塞(sai)泵(beng)(beng)。 乳化液泵(beng)用于(yu)采煤工作(zuo)面，為(wei)液壓支架提供乳化液，工作(zuo)原理靠曲(qu)軸(zhou)的旋轉帶動活塞做往(wang)復運動，實(shi)現吸(xi)液和排液。 軸向式 軸向柱(zhu)塞(sai)(sai)泵（英(ying)文名(ming)：Piston pump）是(shi)(shi)活塞(sai)(sai)或柱(zhu)塞(sai)(sai)的(de)往(wang)復運(yun)動方向與缸(gang)體中心軸平行的(de)柱(zhu)塞(sai)(sai)泵。軸向柱(zhu)塞(sai)(sai)泵利(li)用與傳動軸平行的(de)柱(zhu)塞(sai)(sai)在(zai)柱(zhu)塞(sai)(sai)孔內往(wang)復運(yun)動所產生(sheng)的(de)容積變(bian)化來進(jin)行工作的(de)。由于柱(zhu)塞(sai)(sai)和柱(zhu)塞(sai)(sai)孔都是(shi)(shi)圓(yuan)形零件，加工時可以(yi)達到很高(gao)的(de)精度配合，因(yin)此容積效率(lv)高(gao)。 直軸斜盤式 直軸斜盤(pan)式柱塞泵分為壓(ya)(ya)(ya)力供油(you)(you)型和自(zi)吸油(you)(you)型兩種。壓(ya)(ya)(ya)力供油(you)(you)型液壓(ya)(ya)(ya)泵大都是采(cai)用有氣壓(ya)(ya)(ya)的(de)油(you)(you)箱，靠氣壓(ya)(ya)(ya)供油(you)(you)的(de)液壓(ya)(ya)(ya)油(you)(you)箱，在每次啟(qi)動(dong)機器之后，必須等液壓(ya)(ya)(ya)漬箱達到使(shi)用氣壓(ya)(ya)(ya)后，才(cai)能操作機械。如液壓(ya)(ya)(ya)油(you)(you)箱的(de)氣壓(ya)(ya)(ya)不(bu)足時就(jiu)啟(qi)動(dong)機器，會(hui)對(dui)液壓(ya)(ya)(ya)泵內的(de)與(yu)滑靴造成(cheng)拉脫現象，出會(hui)造成(cheng)泵體(ti)內回(hui)程板與(yu)壓(ya)(ya)(ya)板的(de)非正常磨損。 徑向式 徑(jing)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)泵(beng)可分為(wei)閥配流(liu)與(yu)軸(zhou)配流(liu)兩大(da)(da)類。閥配流(liu)徑(jing)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)泵(beng)存在故(gu)障(zhang)率(lv)高(gao)、效率(lv)低(di)等缺點。上(shang)(shang)70、80年代發展(zhan)的(de)(de)軸(zhou)配流(liu)徑(jing)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)泵(beng)克服了(le)閥配流(liu)徑(jing)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)泵(beng)的(de)(de)不足。由(you)于徑(jing)向(xiang)泵(beng)結構(gou)上(shang)(shang)的(de)(de)特點，固(gu)定(ding)了(le)軸(zhou)配流(liu)徑(jing)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)泵(beng)比軸(zhou)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)泵(beng)耐沖(chong)(chong)擊、壽(shou)命(ming)長(chang)、控制(zhi)精(jing)度高(gao)。變(bian)量(liang)行程短泵(beng)的(de)(de)變(bian)量(liang)是在變(bian)量(liang)柱(zhu)(zhu)(zhu)塞(sai)(sai)和限位柱(zhu)(zhu)(zhu)塞(sai)(sai)作用下，改變(bian)定(ding)子的(de)(de)偏(pian)心距實現的(de)(de)，而定(ding)于的(de)(de)zui大(da)(da)偏(pian)心距為(wei) 5—9mm（根據排(pai)量(liang)大(da)(da)小不同(tong)），變(bian)量(liang)行程很短。且變(bian)量(liang)機構(gou)設計為(wei)高(gao)壓(ya)操縱(zong)，由(you)控制(zhi)閥進行控制(zhi)。故(gu)該泵(beng)的(de)(de)響(xiang)應速(su)度快。徑(jing)向(xiang)結構(gou)設計克服了(le)如軸(zhou)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)泵(beng)滑靴偏(pian)磨的(de)(de)問題。使其抗(kang)沖(chong)(chong)擊能力大(da)(da)幅(fu)度提(ti)高(gao)。 液壓式 液壓(ya)(ya)(ya)柱塞泵靠氣壓(ya)(ya)(ya)供(gong)油(you)(you)(you)的(de)(de)液壓(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang)，在每次啟(qi)動機(ji)器后，必須等液壓(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang)達到使用氣壓(ya)(ya)(ya)后，才能(neng)操作機(ji)械。直(zhi)軸斜盤式柱塞泵分(fen)為(wei)壓(ya)(ya)(ya)力(li)(li)(li)供(gong)油(you)(you)(you)型(xing)(xing)的(de)(de)自吸油(you)(you)(you)型(xing)(xing)兩種。壓(ya)(ya)(ya)力(li)(li)(li)供(gong)油(you)(you)(you)型(xing)(xing)液壓(ya)(ya)(ya)泵大都采用有(you)氣壓(ya)(ya)(ya)的(de)(de)油(you)(you)(you)箱(xiang)(xiang)，也(ye)有(you)液壓(ya)(ya)(ya)泵本身帶有(you)補(bu)油(you)(you)(you)分(fen)泵向液壓(ya)(ya)(ya)泵進油(you)(you)(you)口提(ti)供(gong)壓(ya)(ya)(ya)力(li)(li)(li)油(you)(you)(you)的(de)(de)。自吸油(you)(you)(you)型(xing)(xing)液壓(ya)(ya)(ya)泵的(de)(de)自吸油(you)(you)(you)能(neng)力(li)(li)(li)很強，無需外力(li)(li)(li)供(gong)油(you)(you)(you)。
