機械分類 柱(zhu)塞泵(beng)(beng)一(yi)般分為單柱(zhu)塞泵(beng)(beng)、臥式柱(zhu)塞泵(beng)(beng)、軸(zhou)向(xiang)柱(zhu)塞泵(beng)(beng)和徑向(xiang)柱(zhu)塞泵(beng)(beng)。 單柱塞泵 結構組成主要有偏心(xin)輪、柱塞、彈簧、缸(gang)體、兩個單向(xiang)閥(fa)。柱塞與(yu)(yu)缸(gang)體孔之間形(xing)成密閉容積。偏心(xin)輪旋轉一(yi)(yi)轉，柱塞上下往(wang)復運動一(yi)(yi)次，向(xiang)下運動吸油，向(xiang)上運動排油。泵(beng)每轉一(yi)(yi)轉排出的(de)油液體積稱為排量(liang)，排量(liang)只與(yu)(yu)泵(beng)的(de)結構參數有關。 臥式柱塞泵 臥式(shi)柱(zhu)塞(sai)泵(beng)(beng)是由幾個(ge)柱(zhu)塞(sai)（一(yi)般為3個(ge)或(huo)6個(ge)）并列安(an)裝(zhuang)，用1根曲軸通過(guo)連桿滑塊或(huo)由偏心軸直(zhi)接推(tui)動柱(zhu)塞(sai)做往復運動，實現吸、排液體的液壓泵(beng)(beng)。它們也都(dou)采(cai)用閥式(shi)配流(liu)裝(zhuang)置(zhi)，而且(qie)大多(duo)為定(ding)量泵(beng)(beng)。煤礦液壓支架系統中的乳(ru)化液泵(beng)(beng)一(yi)般都(dou)是臥式(shi)柱(zhu)塞(sai)泵(beng)(beng)。 乳(ru)化液(ye)泵用于采煤工(gong)作(zuo)面(mian)，為(wei)液(ye)壓支架(jia)提供(gong)乳(ru)化液(ye)，工(gong)作(zuo)原理(li)靠曲軸的旋轉帶動(dong)活塞做往復(fu)運動(dong)，實現吸液(ye)和排液(ye)。 軸向式 軸向柱(zhu)塞(sai)(sai)(sai)泵(beng)(beng)（英文名：Piston pump）是活塞(sai)(sai)(sai)或柱(zhu)塞(sai)(sai)(sai)的(de)(de)往復(fu)運(yun)動方向與缸體中心軸平行(xing)的(de)(de)柱(zhu)塞(sai)(sai)(sai)泵(beng)(beng)。軸向柱(zhu)塞(sai)(sai)(sai)泵(beng)(beng)利用與傳(chuan)動軸平行(xing)的(de)(de)柱(zhu)塞(sai)(sai)(sai)在柱(zhu)塞(sai)(sai)(sai)孔(kong)內(nei)往復(fu)運(yun)動所產(chan)生的(de)(de)容(rong)積變化來(lai)進行(xing)工作的(de)(de)。由于(yu)柱(zhu)塞(sai)(sai)(sai)和柱(zhu)塞(sai)(sai)(sai)孔(kong)都(dou)是圓形零(ling)件，加工時(shi)可以達(da)到(dao)很高(gao)的(de)(de)精度配合，因(yin)此容(rong)積效率高(gao)。 直軸斜盤式 直軸(zhou)斜盤式柱(zhu)塞(sai)泵分(fen)為壓(ya)(ya)力供油(you)型和自吸油(you)型兩種。壓(ya)(ya)力供油(you)型液壓(ya)(ya)泵大(da)都(dou)是采(cai)用有(you)氣壓(ya)(ya)的(de)油(you)箱(xiang)，靠氣壓(ya)(ya)供油(you)的(de)液壓(ya)(ya)油(you)箱(xiang)，在每次啟動機器(qi)之后(hou)，必須等液壓(ya)(ya)漬箱(xiang)達到使用氣壓(ya)(ya)后(hou)，才(cai)能操作機械。如液壓(ya)(ya)油(you)箱(xiang)的(de)氣壓(ya)(ya)不足時就啟動機器(qi)，會對(dui)液壓(ya)(ya)泵內(nei)(nei)的(de)與滑(hua)靴造成拉(la)脫現象，出(chu)會造成泵體(ti)內(nei)(nei)回程板(ban)與壓(ya)(ya)板(ban)的(de)非(fei)正(zheng)常磨損。 徑向式 徑向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)泵(beng)(beng)可分(fen)為閥(fa)配(pei)流與軸(zhou)(zhou)配(pei)流兩大(da)類。閥(fa)配(pei)流徑向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)泵(beng)(beng)存在故(gu)障率高(gao)、效(xiao)率低等缺(que)點。上70、80年代發展的(de)(de)(de)軸(zhou)(zhou)配(pei)流徑向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)泵(beng)(beng)克服了(le)閥(fa)配(pei)流徑向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)泵(beng)(beng)的(de)(de)(de)不(bu)足。由(you)于徑向(xiang)(xiang)(xiang)泵(beng)(beng)結構上的(de)(de)(de)特點，固定了(le)軸(zhou)(zhou)配(pei)流徑向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)泵(beng)(beng)比(bi)軸(zhou)(zhou)向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)泵(beng)(beng)耐沖擊、壽(shou)命(ming)長(chang)、控制(zhi)(zhi)精度(du)高(gao)。變量(liang)行(xing)程(cheng)短泵(beng)(beng)的(de)(de)(de)變量(liang)是在變量(liang)柱(zhu)(zhu)塞(sai)(sai)和限位柱(zhu)(zhu)塞(sai)(sai)作用下，改變定子的(de)(de)(de)偏(pian)心距(ju)實現的(de)(de)(de)，而定于的(de)(de)(de)zui大(da)偏(pian)心距(ju)為 5—9mm（根據排量(liang)大(da)小不(bu)同），變量(liang)行(xing)程(cheng)很短。且變量(liang)機構設(she)計為高(gao)壓操縱，由(you)控制(zhi)(zhi)閥(fa)進行(xing)控制(zhi)(zhi)。故(gu)該泵(beng)(beng)的(de)(de)(de)響應速(su)度(du)快。徑向(xiang)(xiang)(xiang)結構設(she)計克服了(le)如軸(zhou)(zhou)向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)泵(beng)(beng)滑靴偏(pian)磨的(de)(de)(de)問(wen)題。使其抗沖擊能力大(da)幅度(du)提(ti)高(gao)。 液壓式 液(ye)(ye)壓(ya)(ya)柱塞泵(beng)靠氣壓(ya)(ya)供(gong)油(you)(you)(you)的(de)(de)液(ye)(ye)壓(ya)(ya)油(you)(you)(you)箱，在每(mei)次啟動機器后，必(bi)須等(deng)液(ye)(ye)壓(ya)(ya)油(you)(you)(you)箱達到使(shi)用氣壓(ya)(ya)后，才能操(cao)作機械(xie)。直軸斜盤(pan)式(shi)柱塞泵(beng)分為壓(ya)(ya)力供(gong)油(you)(you)(you)型的(de)(de)自吸(xi)油(you)(you)(you)型兩種。壓(ya)(ya)力供(gong)油(you)(you)(you)型液(ye)(ye)壓(ya)(ya)泵(beng)大都采用有氣壓(ya)(ya)的(de)(de)油(you)(you)(you)箱，也有液(ye)(ye)壓(ya)(ya)泵(beng)本身帶有補(bu)油(you)(you)(you)分泵(beng)向液(ye)(ye)壓(ya)(ya)泵(beng)進油(you)(you)(you)口(kou)提供(gong)壓(ya)(ya)力油(you)(you)(you)的(de)(de)。自吸(xi)油(you)(you)(you)型液(ye)(ye)壓(ya)(ya)泵(beng)的(de)(de)自吸(xi)油(you)(you)(you)能力很(hen)強，無需外力供(gong)油(you)(you)(you)。
