VICKERS柱塞泵工作原理： VICKERS柱塞(sai)泵是液壓系統的(de)(de)一個重要裝置。它依靠柱塞(sai)在(zai)缸體中(zhong)往(wang)復運動，使密封工作(zuo)容腔的(de)(de)容積發生變化來實現吸油、壓油。柱塞(sai)在(zai)缸體中(zhong)要往(wang)復運動，因(yin)(yin)此，它的(de)(de)運動量很大，在(zai)工作(zuo)過(guo)程(cheng)中(zhong)需要承受(shou)巨大的(de)(de)摩擦(ca)力，因(yin)(yin)此，柱塞(sai)要求高(gao)(gao)的(de)(de)硬度、耐磨性(xing)和使用壽命以及高(gao)(gao)的(de)(de)精(jing)度等。通過(guo)研究，采(cai)用淬火熱處理可以滿足柱塞(sai)的(de)(de)技術要求。
VICKERS柱塞泵的機械分類：
①軸向柱塞泵 軸(zhou)(zhou)(zhou)向(xiang)柱(zhu)塞泵是活塞或柱(zhu)塞的往(wang)復(fu)(fu)運動(dong)方向(xiang)與缸體中心軸(zhou)(zhou)(zhou)平行(xing)的柱(zhu)塞泵。軸(zhou)(zhou)(zhou)向(xiang)柱(zhu)塞泵是利用與傳動(dong)軸(zhou)(zhou)(zhou)平行(xing)的柱(zhu)塞在柱(zhu)塞孔內往(wang)復(fu)(fu)運動(dong)所產生的容積變化(hua)來進(jin)行(xing)工作(zuo)的。由于柱(zhu)塞和(he)柱(zhu)塞孔都(dou)是圓形零件，加工時可以達到很(hen)高(gao)的精度配合，因此容積效(xiao)率高(gao)，運轉平穩，流量(liang)均(jun)勻性好，噪聲低，工作(zuo)壓力高(gao)等優點，但對(dui)液(ye)壓油的污(wu)染較敏感，結構較復(fu)(fu)雜，造價較高(gao)。 ②直軸斜盤式柱塞泵 直軸斜盤式柱塞泵(beng)(beng)(beng)分(fen)為壓(ya)(ya)力供(gong)(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)(gong)油(you)(you)(you)型液(ye)壓(ya)(ya)泵(beng)(beng)(beng)大都(dou)采(cai)用(yong)有氣(qi)壓(ya)(ya)的(de)(de)油(you)(you)(you)箱，也有液(ye)壓(ya)(ya)泵(beng)(beng)(beng)本身帶有補(bu)油(you)(you)(you)分(fen)泵(beng)(beng)(beng)向液(ye)壓(ya)(ya)泵(beng)(beng)(beng)進(jin)油(you)(you)(you)口提供(gong)(gong)壓(ya)(ya)力油(you)(you)(you)的(de)(de)。自吸(xi)油(you)(you)(you)型液(ye)壓(ya)(ya)泵(beng)(beng)(beng)的(de)(de)自吸(xi)油(you)(you)(you)能力很強，無需外力供(gong)(gong)油(you)(you)(you)。靠氣(qi)壓(ya)(ya)供(gong)(gong)油(you)(you)(you)的(de)(de)液(ye)壓(ya)(ya)油(you)(you)(you)箱，在(zai)每次啟動機(ji)器后，必須等液(ye)壓(ya)(ya)漬箱達到使(shi)用(yong)氣(qi)壓(ya)(ya)后，才能操作機(ji)械。如液(ye)壓(ya)(ya)油(you)(you)(you)箱的(de)(de)氣(qi)壓(ya)(ya)不足時(shi)就擔任機(ji)器，會(hui)對液(ye)壓(ya)(ya)泵(beng)(beng)(beng)內的(de)(de)與滑(hua)鞭造(zao)成(cheng)拉脫現象(xiang)，出會(hui)造(zao)成(cheng)泵(beng)(beng)(beng)體內回(hui)程板與壓(ya)(ya)板的(de)(de)非正常磨損(sun)。 ③徑向柱塞泵 徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)可分為閥(fa)配(pei)流(liu)(liu)(liu)與軸(zhou)配(pei)流(liu)(liu)(liu)兩大類。閥(fa)配(pei)流(liu)(liu)(liu)徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)存在故障(zhang)率高(gao)(gao)、效率低等缺點。上70、80年代發(fa)展的(de)(de)(de)軸(zhou)配(pei)流(liu)(liu)(liu)徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)克服了(le)閥(fa)配(pei)流(liu)(liu)(liu)徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)的(de)(de)(de)不足。由(you)(you)于徑(jing)(jing)向泵(beng)(beng)(beng)結構上的(de)(de)(de)特(te)點，陜(shan)定了(le)軸(zhou)配(pei)流(liu)(liu)(liu)徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)比軸(zhou)向柱(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)耐沖(chong)擊、壽(shou)命長、控(kong)制精度高(gao)(gao)。變(bian)(bian)量(liang)行程短泵(beng)(beng)(beng)的(de)(de)(de)變(bian)(bian)量(liang)是在變(bian)(bian)量(liang)柱(zhu)(zhu)塞(sai)和限位柱(zhu)(zhu)塞(sai)作用下，改變(bian)(bian)定子的(de)(de)(de)偏(pian)心(xin)距實現的(de)(de)(de)，而定于的(de)(de)(de)zui大偏(pian)心(xin)距為5—9mm(根據排量(liang)大小不同)，變(bian)(bian)量(liang)行程很短。且變(bian)(bian)量(liang)機構設計為高(gao)(gao)壓操縱，由(you)(you)控(kong)制閥(fa)進行控(kong)制。故該(gai)泵(beng)(beng)(beng)的(de)(de)(de)響(xiang)應速度快。徑(jing)(jing)向結構設計克服了(le)如軸(zhou)向柱(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)滑(hua)靴偏(pian)磨的(de)(de)(de)問題。使(shi)其(qi)抗沖(chong)擊能力大幅度提(ti)高(gao)(gao)。 ④液壓柱塞泵 液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)柱塞泵(beng)(beng)(beng)靠(kao)氣(qi)壓(ya)(ya)(ya)(ya)供(gong)(gong)油(you)(you)(you)(you)的(de)(de)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)箱(xiang)，在(zai)每次啟動機器(qi)后(hou)，必須等(deng)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)漬箱(xiang)達到(dao)使用氣(qi)壓(ya)(ya)(ya)(ya)后(hou)，才能操(cao)作(zuo)機械。直軸斜盤式柱塞泵(beng)(beng)(beng)分為壓(ya)(ya)(ya)(ya)力供(gong)(gong)油(you)(you)(you)(you)型(xing)(xing)的(de)(de)自吸油(you)(you)(you)(you)型(xing)(xing)兩(liang)種。壓(ya)(ya)(ya)(ya)力供(gong)(gong)油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)大都采用有(you)氣(qi)壓(ya)(ya)(ya)(ya)的(de)(de)油(you)(you)(you)(you)箱(xiang)，也有(you)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)本(ben)身帶有(you)補油(you)(you)(you)(you)分泵(beng)(beng)(beng)向液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)進油(you)(you)(you)(you)口(kou)提供(gong)(gong)壓(ya)(ya)(ya)(ya)力油(you)(you)(you)(you)的(de)(de)。自吸油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的(de)(de)自吸油(you)(you)(you)(you)能力很強(qiang)，無需外力供(gong)(gong)油(you)(you)(you)(you)。對(dui)于自吸油(you)(you)(you)(you)型(xing)(xing)柱塞泵(beng)(beng)(beng)，液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)箱(xiang)內(nei)的(de)(de)油(you)(you)(you)(you)液(ye)(ye)(ye)(ye)不得低于油(you)(you)(you)(you)標下限，要保持足夠數量的(de)(de)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)。液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)的(de)(de)清潔度越高，液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的(de)(de)使用壽(shou)命越長(chang)。 威格士柱塞泵工作流程： 威格士柱(zhu)塞泵(beng)柱(zhu)塞往(wang)復(fu)運(yun)動(dong)總行(xing)程(cheng)(cheng)L是不(bu)變(bian)(bian)的(de)，由凸(tu)輪的(de)升程(cheng)(cheng)決定。柱(zhu)塞每循環的(de)供(gong)(gong)油(you)量(liang)大小取(qu)決于供(gong)(gong)油(you)行(xing)程(cheng)(cheng),供(gong)(gong)油(you)行(xing)程(cheng)(cheng)不(bu)受凸(tu)輪軸控制是可(ke)變(bian)(bian)的(de)。供(gong)(gong)油(you)開始時(shi)刻(ke)(ke)不(bu)隨(sui)供(gong)(gong)油(you)行(xing)程(cheng)(cheng)的(de)變(bian)(bian)化(hua)而(er)變(bian)(bian)化(hua)。轉動(dong)柱(zhu)塞可(ke)改變(bian)(bian)供(gong)(gong)油(you)終了時(shi)刻(ke)(ke)，從而(er)改變(bian)(bian)供(gong)(gong)油(you)量(liang)。柱(zhu)塞泵(beng)工作時(shi)，在噴油(you)泵(beng)凸(tu)輪軸上的(de)凸(tu)輪與(yu)柱(zhu)塞彈(dan)簧的(de)作用(yong)下(xia)，迫使柱(zhu)塞作上、下(xia)往(wang)復(fu)運(yun)動(dong)，從而(er)完成泵(beng)油(you)任務，泵(beng)油(you)過(guo)程(cheng)(cheng)可(ke)分為以下(xia)三個階段。 進油過程 當凸輪的凸起(qi)部分轉過去(qu)后(hou)，在彈簧(huang)力(li)的作(zuo)用下(xia)，柱(zhu)(zhu)塞(sai)向下(xia)運動(dong)，柱(zhu)(zhu)塞(sai)上(shang)部空間（稱為(wei)泵(beng)(beng)油(you)室(shi)(shi)）產生真(zhen)空度，當柱(zhu)(zhu)塞(sai)上(shang)端面把柱(zhu)(zhu)塞(sai)套(tao)上(shang)的進(jin)油(you)孔打開后(hou)，充滿在油(you)泵(beng)(beng)上(shang)體油(you)道內的柴油(you)經油(you)孔進(jin)入(ru)泵(beng)(beng)油(you)室(shi)(shi)，柱(zhu)(zhu)塞(sai)運動(dong)到下(xia)止點，進(jin)油(you)結束。 供油過程 當凸(tu)輪軸轉到凸(tu)輪的凸(tu)起(qi)部(bu)(bu)分(fen)頂(ding)起(qi)滾輪體時，柱(zhu)塞(sai)彈簧被壓(ya)縮，柱(zhu)塞(sai)向上運動，燃(ran)(ran)油(you)(you)(you)(you)(you)(you)(you)受壓(ya)，一部(bu)(bu)分(fen)燃(ran)(ran)油(you)(you)(you)(you)(you)(you)(you)經油(you)(you)(you)(you)(you)(you)(you)孔(kong)流(liu)回噴油(you)(you)(you)(you)(you)(you)(you)泵上體油(you)(you)(you)(you)(you)(you)(you)腔。當柱(zhu)塞(sai)頂(ding)面遮(zhe)住套(tao)筒(tong)上進(jin)油(you)(you)(you)(you)(you)(you)(you)孔(kong)的上緣時，由于柱(zhu)塞(sai)和套(tao)筒(tong)的配合(he)間隙很小（0.0015-0.0025mm）使(shi)柱(zhu)塞(sai)頂(ding)部(bu)(bu)的泵油(you)(you)(you)(you)(you)(you)(you)室成為一個密封油(you)(you)(you)(you)(you)(you)(you)腔，柱(zhu)塞(sai)繼續上升(sheng)，泵油(you)(you)(you)(you)(you)(you)(you)室內的油(you)(you)(you)(you)(you)(you)(you)壓(ya)迅速升(sheng)高，泵油(you)(you)(you)(you)(you)(you)(you)壓(ya)力>出(chu)油(you)(you)(you)(you)(you)(you)(you)閥彈簧力+高壓(ya)油(you)(you)(you)(you)(you)(you)(you)管(guan)(guan)剩余壓(ya)力時，推開出(chu)油(you)(you)(you)(you)(you)(you)(you)閥，高壓(ya)柴油(you)(you)(you)(you)(you)(you)(you)經出(chu)油(you)(you)(you)(you)(you)(you)(you)閥進(jin)入高壓(ya)油(you)(you)(you)(you)(you)(you)(you)管(guan)(guan)，通過噴油(you)(you)(you)(you)(you)(you)(you)器(qi)噴入燃(ran)(ran)燒室。 回油過程 柱塞(sai)向(xiang)(xiang)上供(gong)油，當(dang)上行(xing)到柱塞(sai)上的(de)斜槽（停供(gong)邊）與(yu)套筒上的(de)回油孔(kong)相通時，泵油室低壓油路便與(yu)柱塞(sai)頭部(bu)的(de)中孔(kong)和徑向(xiang)(xiang)孔(kong)及斜槽溝通，油壓驟然(ran)下降(jiang)，出油閥在彈簧力的(de)作用下迅速關閉，停止供(gong)油。此(ci)后(hou)柱塞(sai)還要上行(xing)，當(dang)凸(tu)輪的(de)凸(tu)起部(bu)分轉過去后(hou)，在彈簧的(de)作用下，柱塞(sai)又下行(xing)。此(ci)時便開始(shi)了下一個循環。 柱塞泵以(yi)一(yi)個(ge)柱塞為原理介紹，一(yi)個(ge)柱塞泵上有兩個(ge)單(dan)向(xiang)(xiang)閥，并且方(fang)向(xiang)(xiang)相反，柱塞向(xiang)(xiang)一(yi)個(ge)方(fang)向(xiang)(xiang)運(yun)(yun)動(dong)時(shi)(shi)缸(gang)(gang)內出現負壓(ya)，這時(shi)(shi)一(yi)個(ge)單(dan)向(xiang)(xiang)閥打(da)開(kai)液(ye)(ye)體(ti)被吸(xi)入缸(gang)(gang)內，柱塞向(xiang)(xiang)另一(yi)個(ge)方(fang)向(xiang)(xiang)運(yun)(yun)動(dong)時(shi)(shi)，將液(ye)(ye)體(ti)壓(ya)縮后另一(yi)個(ge)單(dan)向(xiang)(xiang)閥被打(da)開(kai)，被吸(xi)入缸(gang)(gang)內的液(ye)(ye)體(ti)被排出。這種(zhong)工(gong)作(zuo)方(fang)式連續運(yun)(yun)動(dong)后就形成了連續供油(you) 。 VICKERS柱塞(sai)泵的特(te)點： 【1】VICKERS柱塞(sai)泵具有額(e)定(ding)壓力高、結構緊(jin)湊、效率高和流量調節(jie)方便(bian)等優(you)點。 【2】 VICKERS柱(zhu)塞(sai)泵是利用與(yu)傳動軸平行的(de)(de)柱(zhu)塞(sai)在(zai)柱(zhu)塞(sai)孔內(nei)往復運動所產生的(de)(de)容積變化來進行工作的(de)(de)。由于柱(zhu)塞(sai)和柱(zhu)塞(sai)孔都(dou)是圓(yuan)形零件(jian)，加工時可以達到很高的(de)(de)精(jing)度配(pei)合，因此具有(you)容積效率高，運轉(zhuan)平穩，流(liu)量均勻性好，噪聲低，工作壓(ya)力高等優點，但對液壓(ya)油的(de)(de)污染(ran)較敏感，結構較復雜，造價較高。 【3】柱(zhu)塞泵(beng)(beng)依靠柱(zhu)塞在缸體(ti)中(zhong)往復運動，使密封工作容腔的(de)容積發生變化來實現吸油、壓(ya)油。大(da)金柱(zhu)塞泵(beng)(beng)，柱(zhu)塞泵(beng)(beng)，VICKERS柱(zhu)塞泵(beng)(beng)被廣泛應用于高(gao)壓(ya)、大(da)流量(liang)和(he)(he)流量(liang)需要調節的(de)場(chang)合，諸如液壓(ya)機、工程機械和(he)(he)船舶中(zhong)。
