威格士柱塞泵工作流程： 威格士柱(zhu)塞(sai)(sai)泵(beng)柱(zhu)塞(sai)(sai)往復運(yun)(yun)動(dong)總行(xing)程L是不(bu)變的(de)(de)(de)，由凸輪的(de)(de)(de)升程決(jue)(jue)定(ding)。柱(zhu)塞(sai)(sai)每(mei)循環的(de)(de)(de)供(gong)油量(liang)大小取決(jue)(jue)于供(gong)油行(xing)程,供(gong)油行(xing)程不(bu)受凸輪軸控制是可變的(de)(de)(de)。供(gong)油開始(shi)時刻(ke)不(bu)隨供(gong)油行(xing)程的(de)(de)(de)變化(hua)(hua)而變化(hua)(hua)。轉動(dong)柱(zhu)塞(sai)(sai)可改(gai)變供(gong)油終(zhong)了(le)時刻(ke)，從而改(gai)變供(gong)油量(liang)。柱(zhu)塞(sai)(sai)泵(beng)工作(zuo)(zuo)時，在噴油泵(beng)凸輪軸上的(de)(de)(de)凸輪與柱(zhu)塞(sai)(sai)彈簧的(de)(de)(de)作(zuo)(zuo)用下，迫使(shi)柱(zhu)塞(sai)(sai)作(zuo)(zuo)上、下往復運(yun)(yun)動(dong)，從而完(wan)成泵(beng)油任務，泵(beng)油過(guo)程可分為以下三個階(jie)段。 進油過程 當(dang)凸輪的(de)凸起部分(fen)轉過去后，在(zai)(zai)彈簧力的(de)作(zuo)用下(xia)，柱塞向下(xia)運動，柱塞上(shang)部空間（稱為(wei)泵(beng)(beng)(beng)油(you)(you)室）產(chan)生真空度，當(dang)柱塞上(shang)端面(mian)把柱塞套上(shang)的(de)進(jin)油(you)(you)孔(kong)打開后，充(chong)滿在(zai)(zai)油(you)(you)泵(beng)(beng)(beng)上(shang)體(ti)油(you)(you)道內的(de)柴(chai)油(you)(you)經油(you)(you)孔(kong)進(jin)入泵(beng)(beng)(beng)油(you)(you)室，柱塞運動到下(xia)止點，進(jin)油(you)(you)結(jie)束。 供油過程 當(dang)凸(tu)(tu)輪軸轉(zhuan)到(dao)凸(tu)(tu)輪的(de)(de)凸(tu)(tu)起部分頂(ding)(ding)起滾輪體時，柱(zhu)塞(sai)彈(dan)簧被壓(ya)縮，柱(zhu)塞(sai)向上運動，燃油(you)(you)(you)(you)受壓(ya)，一(yi)部分燃油(you)(you)(you)(you)經油(you)(you)(you)(you)孔(kong)流(liu)回(hui)噴油(you)(you)(you)(you)泵(beng)上體油(you)(you)(you)(you)腔(qiang)。當(dang)柱(zhu)塞(sai)頂(ding)(ding)面遮住套筒上進(jin)(jin)油(you)(you)(you)(you)孔(kong)的(de)(de)上緣時，由于柱(zhu)塞(sai)和套筒的(de)(de)配(pei)合間隙很小（0.0015-0.0025mm）使柱(zhu)塞(sai)頂(ding)(ding)部的(de)(de)泵(beng)油(you)(you)(you)(you)室成(cheng)為一(yi)個密封油(you)(you)(you)(you)腔(qiang)，柱(zhu)塞(sai)繼續上升，泵(beng)油(you)(you)(you)(you)室內的(de)(de)油(you)(you)(you)(you)壓(ya)迅速升高(gao)，泵(beng)油(you)(you)(you)(you)壓(ya)力(li)>出油(you)(you)(you)(you)閥(fa)(fa)彈(dan)簧力(li)+高(gao)壓(ya)油(you)(you)(you)(you)管剩余壓(ya)力(li)時，推(tui)開出油(you)(you)(you)(you)閥(fa)(fa)，高(gao)壓(ya)柴油(you)(you)(you)(you)經出油(you)(you)(you)(you)閥(fa)(fa)進(jin)(jin)入高(gao)壓(ya)油(you)(you)(you)(you)管，通過(guo)噴油(you)(you)(you)(you)器噴入燃燒室。 回油過程 柱塞向上(shang)供(gong)油(you)，當(dang)(dang)上(shang)行(xing)(xing)(xing)到(dao)柱塞上(shang)的(de)(de)斜(xie)槽（停(ting)供(gong)邊）與(yu)套筒上(shang)的(de)(de)回油(you)孔相通(tong)時，泵油(you)室低壓油(you)路便(bian)與(yu)柱塞頭部的(de)(de)中孔和徑向孔及斜(xie)槽溝通(tong)，油(you)壓驟然下(xia)降(jiang)，出油(you)閥(fa)在彈簧(huang)力的(de)(de)作用下(xia)迅(xun)速關閉，停(ting)止供(gong)油(you)。此后柱塞還(huan)要上(shang)行(xing)(xing)(xing)，當(dang)(dang)凸輪的(de)(de)凸起部分轉過去后，在彈簧(huang)的(de)(de)作用下(xia)，柱塞又下(xia)行(xing)(xing)(xing)。此時便(bian)開始了下(xia)一個循環。 柱(zhu)(zhu)塞(sai)泵以(yi)一個(ge)(ge)柱(zhu)(zhu)塞(sai)為原理介紹，一個(ge)(ge)柱(zhu)(zhu)塞(sai)泵上有兩個(ge)(ge)單(dan)向(xiang)閥，并且(qie)方(fang)向(xiang)相(xiang)反，柱(zhu)(zhu)塞(sai)向(xiang)一個(ge)(ge)方(fang)向(xiang)運(yun)動(dong)時(shi)缸內出(chu)現負壓(ya)(ya)，這(zhe)時(shi)一個(ge)(ge)單(dan)向(xiang)閥打開(kai)液(ye)體(ti)被吸入(ru)缸內，柱(zhu)(zhu)塞(sai)向(xiang)另一個(ge)(ge)方(fang)向(xiang)運(yun)動(dong)時(shi)，將液(ye)體(ti)壓(ya)(ya)縮后(hou)另一個(ge)(ge)單(dan)向(xiang)閥被打開(kai)，被吸入(ru)缸內的液(ye)體(ti)被排出(chu)。這(zhe)種工作方(fang)式連續(xu)運(yun)動(dong)后(hou)就形成了連續(xu)供油 。 VICKERS柱塞泵的機械分類： ①軸向柱塞泵 軸向(xiang)(xiang)柱(zhu)塞(sai)泵(beng)是活塞(sai)或柱(zhu)塞(sai)的(de)(de)往(wang)復運動(dong)方(fang)向(xiang)(xiang)與缸體(ti)中心軸平(ping)行(xing)的(de)(de)柱(zhu)塞(sai)泵(beng)。軸向(xiang)(xiang)柱(zhu)塞(sai)泵(beng)是利用與傳動(dong)軸平(ping)行(xing)的(de)(de)柱(zhu)塞(sai)在柱(zhu)塞(sai)孔(kong)內往(wang)復運動(dong)所產(chan)生的(de)(de)容積(ji)變化來(lai)進行(xing)工(gong)作的(de)(de)。由于柱(zhu)塞(sai)和柱(zhu)塞(sai)孔(kong)都是圓形零件，加工(gong)時可以達到很(hen)高(gao)的(de)(de)精(jing)度配合(he)，因(yin)此容積(ji)效(xiao)率高(gao)，運轉(zhuan)平(ping)穩，流量均勻性好，噪聲低，工(gong)作壓力高(gao)等(deng)優(you)點，但(dan)對液壓油的(de)(de)污染較敏感，結構較復雜，造價較高(gao)。 ②直軸斜盤式柱塞泵 直軸斜盤式(shi)柱(zhu)塞泵(beng)(beng)(beng)分為(wei)壓(ya)(ya)力(li)供(gong)(gong)油(you)(you)(you)型的(de)(de)自(zi)(zi)吸油(you)(you)(you)型兩種。壓(ya)(ya)力(li)供(gong)(gong)油(you)(you)(you)型液(ye)(ye)壓(ya)(ya)泵(beng)(beng)(beng)大都采用有(you)氣(qi)(qi)(qi)壓(ya)(ya)的(de)(de)油(you)(you)(you)箱，也有(you)液(ye)(ye)壓(ya)(ya)泵(beng)(beng)(beng)本身(shen)帶有(you)補(bu)油(you)(you)(you)分泵(beng)(beng)(beng)向液(ye)(ye)壓(ya)(ya)泵(beng)(beng)(beng)進(jin)油(you)(you)(you)口提(ti)供(gong)(gong)壓(ya)(ya)力(li)油(you)(you)(you)的(de)(de)。自(zi)(zi)吸油(you)(you)(you)型液(ye)(ye)壓(ya)(ya)泵(beng)(beng)(beng)的(de)(de)自(zi)(zi)吸油(you)(you)(you)能力(li)很強，無需外力(li)供(gong)(gong)油(you)(you)(you)。靠氣(qi)(qi)(qi)壓(ya)(ya)供(gong)(gong)油(you)(you)(you)的(de)(de)液(ye)(ye)壓(ya)(ya)油(you)(you)(you)箱，在每次啟動機器后(hou)，必須(xu)等液(ye)(ye)壓(ya)(ya)漬箱達到使用氣(qi)(qi)(qi)壓(ya)(ya)后(hou)，才能操作(zuo)機械。如液(ye)(ye)壓(ya)(ya)油(you)(you)(you)箱的(de)(de)氣(qi)(qi)(qi)壓(ya)(ya)不(bu)足時(shi)就(jiu)擔任機器，會對液(ye)(ye)壓(ya)(ya)泵(beng)(beng)(beng)內的(de)(de)與(yu)(yu)滑(hua)鞭造成(cheng)拉脫現象，出(chu)會造成(cheng)泵(beng)(beng)(beng)體內回程板與(yu)(yu)壓(ya)(ya)板的(de)(de)非正常磨損。 ③徑向柱塞泵 徑(jing)(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)(zhu)塞(sai)泵可分為閥(fa)配(pei)流(liu)(liu)與軸(zhou)配(pei)流(liu)(liu)兩大(da)類。閥(fa)配(pei)流(liu)(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)(zhu)塞(sai)泵存(cun)在故障(zhang)率高(gao)、效率低(di)等缺(que)點。上70、80年代發展的軸(zhou)配(pei)流(liu)(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)(zhu)塞(sai)泵克(ke)服(fu)了閥(fa)配(pei)流(liu)(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)(zhu)塞(sai)泵的不(bu)(bu)足。由(you)于徑(jing)(jing)向(xiang)(xiang)(xiang)泵結構上的特點，陜定(ding)了軸(zhou)配(pei)流(liu)(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)(zhu)塞(sai)泵比軸(zhou)向(xiang)(xiang)(xiang)柱(zhu)(zhu)(zhu)塞(sai)泵耐沖擊(ji)、壽命長、控制精度高(gao)。變量行(xing)程(cheng)短泵的變量是在變量柱(zhu)(zhu)(zhu)塞(sai)和(he)限(xian)位柱(zhu)(zhu)(zhu)塞(sai)作用下(xia)，改變定(ding)子的偏(pian)心距實現(xian)的，而(er)定(ding)于的zui大(da)偏(pian)心距為5—9mm(根據排量大(da)小不(bu)(bu)同)，變量行(xing)程(cheng)很(hen)短。且變量機構設(she)計為高(gao)壓(ya)操縱(zong)，由(you)控制閥(fa)進行(xing)控制。故該泵的響應速度快。徑(jing)(jing)向(xiang)(xiang)(xiang)結構設(she)計克(ke)服(fu)了如軸(zhou)向(xiang)(xiang)(xiang)柱(zhu)(zhu)(zhu)塞(sai)泵滑靴(xue)偏(pian)磨(mo)的問題(ti)。使其抗沖擊(ji)能力大(da)幅(fu)度提高(gao)。 ④液壓柱塞泵 液(ye)壓(ya)(ya)柱塞泵(beng)靠氣(qi)壓(ya)(ya)供(gong)(gong)(gong)油(you)(you)(you)(you)的(de)(de)(de)(de)液(ye)壓(ya)(ya)油(you)(you)(you)(you)箱，在每次啟(qi)動機器后，必(bi)須等(deng)液(ye)壓(ya)(ya)漬箱達(da)到使(shi)用(yong)氣(qi)壓(ya)(ya)后，才能(neng)操作(zuo)機械。直軸斜(xie)盤式柱塞泵(beng)分為壓(ya)(ya)力(li)(li)(li)供(gong)(gong)(gong)油(you)(you)(you)(you)型的(de)(de)(de)(de)自(zi)吸油(you)(you)(you)(you)型兩種。壓(ya)(ya)力(li)(li)(li)供(gong)(gong)(gong)油(you)(you)(you)(you)型液(ye)壓(ya)(ya)泵(beng)大都(dou)采用(yong)有(you)(you)氣(qi)壓(ya)(ya)的(de)(de)(de)(de)油(you)(you)(you)(you)箱，也有(you)(you)液(ye)壓(ya)(ya)泵(beng)本身帶有(you)(you)補油(you)(you)(you)(you)分泵(beng)向液(ye)壓(ya)(ya)泵(beng)進油(you)(you)(you)(you)口提供(gong)(gong)(gong)壓(ya)(ya)力(li)(li)(li)油(you)(you)(you)(you)的(de)(de)(de)(de)。自(zi)吸油(you)(you)(you)(you)型液(ye)壓(ya)(ya)泵(beng)的(de)(de)(de)(de)自(zi)吸油(you)(you)(you)(you)能(neng)力(li)(li)(li)很強，無需外力(li)(li)(li)供(gong)(gong)(gong)油(you)(you)(you)(you)。對于自(zi)吸油(you)(you)(you)(you)型柱塞泵(beng)，液(ye)壓(ya)(ya)油(you)(you)(you)(you)箱內的(de)(de)(de)(de)油(you)(you)(you)(you)液(ye)不得(de)低于油(you)(you)(you)(you)標下限，要保持足夠數量的(de)(de)(de)(de)液(ye)壓(ya)(ya)油(you)(you)(you)(you)。液(ye)壓(ya)(ya)油(you)(you)(you)(you)的(de)(de)(de)(de)清潔度越高，液(ye)壓(ya)(ya)泵(beng)的(de)(de)(de)(de)使(shi)用(yong)壽命越長。
