機械分類 柱(zhu)塞(sai)(sai)(sai)泵(beng)一般分為單(dan)柱(zhu)塞(sai)(sai)(sai)泵(beng)、臥式柱(zhu)塞(sai)(sai)(sai)泵(beng)、軸向柱(zhu)塞(sai)(sai)(sai)泵(beng)和徑向柱(zhu)塞(sai)(sai)(sai)泵(beng)。 單柱塞泵 結構組成(cheng)主要有偏心輪(lun)、柱塞、彈簧、缸(gang)(gang)體(ti)、兩個單(dan)向閥。柱塞與缸(gang)(gang)體(ti)孔(kong)之間形成(cheng)密閉(bi)容積。偏心輪(lun)旋轉(zhuan)一(yi)轉(zhuan)，柱塞上下(xia)往復運動(dong)一(yi)次，向下(xia)運動(dong)吸油(you)，向上運動(dong)排(pai)油(you)。泵每轉(zhuan)一(yi)轉(zhuan)排(pai)出的(de)油(you)液體(ti)積稱(cheng)為排(pai)量，排(pai)量只(zhi)與泵的(de)結構參(can)數有關(guan)。 臥式柱塞泵 臥(wo)式柱塞(sai)泵(beng)是(shi)由(you)幾個(ge)柱塞(sai)（一(yi)般為3個(ge)或6個(ge)）并列安裝(zhuang)(zhuang)，用1根曲(qu)軸(zhou)通過(guo)連桿滑塊或由(you)偏(pian)心軸(zhou)直接推動(dong)柱塞(sai)做往(wang)復(fu)運動(dong)，實現吸、排液體的液壓(ya)泵(beng)。它們也都(dou)采用閥(fa)式配流裝(zhuang)(zhuang)置，而(er)且大多為定量泵(beng)。煤礦(kuang)液壓(ya)支架系統中的乳化液泵(beng)一(yi)般都(dou)是(shi)臥(wo)式柱塞(sai)泵(beng)。 ; 乳化(hua)液泵用于采(cai)煤工作面，為液壓支(zhi)架提供乳化(hua)液，工作原理靠(kao)曲軸的旋轉帶(dai)動活塞做往(wang)復運(yun)動，實現(xian)吸(xi)液和排液。 軸向式 軸(zhou)向柱(zhu)塞(sai)(sai)泵(beng)(beng)（英文名(ming)：Piston pump）是活塞(sai)(sai)或柱(zhu)塞(sai)(sai)的(de)(de)往復運動(dong)方向與(yu)缸體中心軸(zhou)平(ping)行的(de)(de)柱(zhu)塞(sai)(sai)泵(beng)(beng)。軸(zhou)向柱(zhu)塞(sai)(sai)泵(beng)(beng)利用與(yu)傳動(dong)軸(zhou)平(ping)行的(de)(de)柱(zhu)塞(sai)(sai)在柱(zhu)塞(sai)(sai)孔內往復運動(dong)所產生(sheng)的(de)(de)容積(ji)變化來進行工作的(de)(de)。由于柱(zhu)塞(sai)(sai)和柱(zhu)塞(sai)(sai)孔都是圓形(xing)零件(jian)，加工時可(ke)以達到很高(gao)的(de)(de)精度(du)配(pei)合，因此容積(ji)效率(lv)高(gao)。 直軸斜盤式 直軸斜盤式(shi)柱塞(sai)泵(beng)分為壓(ya)(ya)(ya)(ya)力供(gong)油(you)型(xing)和自吸(xi)油(you)型(xing)兩(liang)種。壓(ya)(ya)(ya)(ya)力供(gong)油(you)型(xing)液(ye)壓(ya)(ya)(ya)(ya)泵(beng)大(da)都是采用有(you)氣壓(ya)(ya)(ya)(ya)的(de)油(you)箱，靠氣壓(ya)(ya)(ya)(ya)供(gong)油(you)的(de)液(ye)壓(ya)(ya)(ya)(ya)油(you)箱，在每次(ci)啟動機(ji)器之后(hou)，必須等液(ye)壓(ya)(ya)(ya)(ya)漬箱達(da)到使(shi)用氣壓(ya)(ya)(ya)(ya)后(hou)，才能(neng)操作機(ji)械。如液(ye)壓(ya)(ya)(ya)(ya)油(you)箱的(de)氣壓(ya)(ya)(ya)(ya)不足(zu)時就啟動機(ji)器，會(hui)對液(ye)壓(ya)(ya)(ya)(ya)泵(beng)內(nei)的(de)與滑靴造(zao)成拉脫現(xian)象(xiang)，出會(hui)造(zao)成泵(beng)體內(nei)回程板(ban)與壓(ya)(ya)(ya)(ya)板(ban)的(de)非(fei)正常磨損。 徑向式 徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)(beng)(beng)(beng)可分為(wei)(wei)閥配(pei)流(liu)(liu)與軸(zhou)配(pei)流(liu)(liu)兩大(da)類。閥配(pei)流(liu)(liu)徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)(beng)(beng)(beng)存(cun)在(zai)故障率高(gao)、效(xiao)率低等(deng)缺點(dian)。上70、80年代(dai)發(fa)展的(de)(de)軸(zhou)配(pei)流(liu)(liu)徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)(beng)(beng)(beng)克服(fu)了閥配(pei)流(liu)(liu)徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)不足。由于徑向(xiang)泵(beng)(beng)(beng)(beng)(beng)(beng)結構上的(de)(de)特(te)點(dian)，固定了軸(zhou)配(pei)流(liu)(liu)徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)(beng)(beng)(beng)比(bi)軸(zhou)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)(beng)(beng)(beng)耐沖(chong)擊(ji)、壽(shou)命長、控制精度高(gao)。變(bian)(bian)量(liang)(liang)(liang)行程短(duan)泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)變(bian)(bian)量(liang)(liang)(liang)是在(zai)變(bian)(bian)量(liang)(liang)(liang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)和限位(wei)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)作用下，改(gai)變(bian)(bian)定子的(de)(de)偏(pian)心距實現的(de)(de)，而定于的(de)(de)zui大(da)偏(pian)心距為(wei)(wei) 5—9mm（根據排(pai)量(liang)(liang)(liang)大(da)小不同），變(bian)(bian)量(liang)(liang)(liang)行程很短(duan)。且(qie)變(bian)(bian)量(liang)(liang)(liang)機(ji)構設(she)計(ji)為(wei)(wei)高(gao)壓操(cao)縱，由控制閥進(jin)行控制。故該泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)響應速度快。徑向(xiang)結構設(she)計(ji)克服(fu)了如軸(zhou)向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)(beng)(beng)(beng)滑靴(xue)偏(pian)磨的(de)(de)問題(ti)。使(shi)其抗沖(chong)擊(ji)能力大(da)幅度提高(gao)。 液壓式 液(ye)(ye)(ye)壓(ya)柱塞泵靠氣(qi)壓(ya)供(gong)油(you)(you)(you)(you)的(de)液(ye)(ye)(ye)壓(ya)油(you)(you)(you)(you)箱(xiang)，在(zai)每(mei)次啟動機(ji)器后(hou)，必須等液(ye)(ye)(ye)壓(ya)油(you)(you)(you)(you)箱(xiang)達到使用氣(qi)壓(ya)后(hou)，才(cai)能操作機(ji)械。直軸(zhou)斜盤式柱塞泵分為壓(ya)力(li)供(gong)油(you)(you)(you)(you)型(xing)的(de)自吸(xi)油(you)(you)(you)(you)型(xing)兩(liang)種。壓(ya)力(li)供(gong)油(you)(you)(you)(you)型(xing)液(ye)(ye)(ye)壓(ya)泵大都采用有(you)氣(qi)壓(ya)的(de)油(you)(you)(you)(you)箱(xiang)，也有(you)液(ye)(ye)(ye)壓(ya)泵本身帶有(you)補油(you)(you)(you)(you)分泵向液(ye)(ye)(ye)壓(ya)泵進油(you)(you)(you)(you)口提(ti)供(gong)壓(ya)力(li)油(you)(you)(you)(you)的(de)。自吸(xi)油(you)(you)(you)(you)型(xing)液(ye)(ye)(ye)壓(ya)泵的(de)自吸(xi)油(you)(you)(you)(you)能力(li)很強，無需外力(li)供(gong)油(you)(you)(you)(you)。
