VICKERS柱塞泵工作原理： VICKERS柱(zhu)塞(sai)泵(beng)是液壓系統的(de)(de)(de)一(yi)個重要(yao)(yao)裝(zhuang)置。它依靠柱(zhu)塞(sai)在缸(gang)體中(zhong)往(wang)復運動(dong)，使密封工作(zuo)容腔的(de)(de)(de)容積(ji)發生變化來實現吸油、壓油。柱(zhu)塞(sai)在缸(gang)體中(zhong)要(yao)(yao)往(wang)復運動(dong)，因(yin)此(ci)(ci)，它的(de)(de)(de)運動(dong)量很大，在工作(zuo)過程中(zhong)需要(yao)(yao)承受(shou)巨大的(de)(de)(de)摩擦力，因(yin)此(ci)(ci)，柱(zhu)塞(sai)要(yao)(yao)求高(gao)的(de)(de)(de)硬度、耐磨性和(he)使用壽命以及高(gao)的(de)(de)(de)精(jing)度等。通過研究(jiu)，采(cai)用淬火熱處(chu)理可以滿足柱(zhu)塞(sai)的(de)(de)(de)技術(shu)要(yao)(yao)求。
VICKERS柱塞泵的機械分類：
①軸向柱塞泵 軸(zhou)(zhou)(zhou)向柱(zhu)(zhu)塞(sai)泵(beng)是活塞(sai)或柱(zhu)(zhu)塞(sai)的(de)(de)往復(fu)運動(dong)方向與缸體中心軸(zhou)(zhou)(zhou)平行(xing)的(de)(de)柱(zhu)(zhu)塞(sai)泵(beng)。軸(zhou)(zhou)(zhou)向柱(zhu)(zhu)塞(sai)泵(beng)是利(li)用與傳動(dong)軸(zhou)(zhou)(zhou)平行(xing)的(de)(de)柱(zhu)(zhu)塞(sai)在柱(zhu)(zhu)塞(sai)孔內往復(fu)運動(dong)所產生的(de)(de)容(rong)積(ji)變化來進(jin)行(xing)工(gong)作的(de)(de)。由于(yu)柱(zhu)(zhu)塞(sai)和柱(zhu)(zhu)塞(sai)孔都是圓形(xing)零件，加工(gong)時可以達到很(hen)高的(de)(de)精度(du)配合，因此容(rong)積(ji)效率高，運轉平穩(wen)，流量(liang)均勻性好，噪(zao)聲低，工(gong)作壓(ya)力高等優點，但對液壓(ya)油的(de)(de)污染較敏(min)感(gan)，結構較復(fu)雜，造價較高。 ②直軸斜盤式柱塞泵 直軸斜盤(pan)式柱塞泵(beng)(beng)(beng)分為壓(ya)(ya)(ya)(ya)(ya)力(li)供(gong)油(you)(you)(you)(you)(you)型(xing)的(de)(de)自(zi)吸油(you)(you)(you)(you)(you)型(xing)兩(liang)種。壓(ya)(ya)(ya)(ya)(ya)力(li)供(gong)油(you)(you)(you)(you)(you)型(xing)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)大都采用有(you)(you)氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)油(you)(you)(you)(you)(you)箱(xiang)(xiang)，也(ye)有(you)(you)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)本身帶有(you)(you)補油(you)(you)(you)(you)(you)分泵(beng)(beng)(beng)向液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)進(jin)油(you)(you)(you)(you)(you)口(kou)提(ti)供(gong)壓(ya)(ya)(ya)(ya)(ya)力(li)油(you)(you)(you)(you)(you)的(de)(de)。自(zi)吸油(you)(you)(you)(you)(you)型(xing)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的(de)(de)自(zi)吸油(you)(you)(you)(you)(you)能(neng)(neng)力(li)很強，無需外力(li)供(gong)油(you)(you)(you)(you)(you)。靠氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)供(gong)油(you)(you)(you)(you)(you)的(de)(de)液(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)(you)箱(xiang)(xiang)，在每(mei)次啟(qi)動機器后(hou)，必須(xu)等液(ye)壓(ya)(ya)(ya)(ya)(ya)漬箱(xiang)(xiang)達到使用氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)后(hou)，才能(neng)(neng)操作機械。如液(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)(you)箱(xiang)(xiang)的(de)(de)氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)不足時就(jiu)擔任機器，會對液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)內(nei)的(de)(de)與滑(hua)鞭造(zao)成拉脫現象(xiang)，出會造(zao)成泵(beng)(beng)(beng)體(ti)內(nei)回程板與壓(ya)(ya)(ya)(ya)(ya)板的(de)(de)非正(zheng)常磨損。 ③徑向柱塞泵 徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵可分為(wei)閥(fa)配(pei)(pei)流與(yu)軸(zhou)配(pei)(pei)流兩大(da)類(lei)。閥(fa)配(pei)(pei)流徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵存在(zai)故(gu)障率高(gao)(gao)、效率低等缺點。上(shang)(shang)70、80年代發展的軸(zhou)配(pei)(pei)流徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵克(ke)服(fu)了閥(fa)配(pei)(pei)流徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵的不足。由于(yu)徑(jing)(jing)向泵結(jie)構(gou)(gou)(gou)上(shang)(shang)的特點，陜定(ding)(ding)了軸(zhou)配(pei)(pei)流徑(jing)(jing)向柱(zhu)(zhu)塞(sai)泵比(bi)軸(zhou)向柱(zhu)(zhu)塞(sai)泵耐沖(chong)擊(ji)、壽(shou)命(ming)長、控制精度(du)高(gao)(gao)。變(bian)量行(xing)(xing)程短泵的變(bian)量是在(zai)變(bian)量柱(zhu)(zhu)塞(sai)和限位柱(zhu)(zhu)塞(sai)作用(yong)下(xia)，改變(bian)定(ding)(ding)子的偏(pian)心距(ju)(ju)實現的，而定(ding)(ding)于(yu)的zui大(da)偏(pian)心距(ju)(ju)為(wei)5—9mm(根(gen)據排量大(da)小(xiao)不同)，變(bian)量行(xing)(xing)程很短。且變(bian)量機構(gou)(gou)(gou)設(she)計為(wei)高(gao)(gao)壓操縱，由控制閥(fa)進行(xing)(xing)控制。故(gu)該泵的響應速度(du)快。徑(jing)(jing)向結(jie)構(gou)(gou)(gou)設(she)計克(ke)服(fu)了如軸(zhou)向柱(zhu)(zhu)塞(sai)泵滑靴偏(pian)磨的問題(ti)。使(shi)其抗沖(chong)擊(ji)能力(li)大(da)幅度(du)提高(gao)(gao)。 ④液壓柱塞泵 液(ye)(ye)(ye)(ye)壓(ya)(ya)柱塞(sai)泵靠氣(qi)壓(ya)(ya)供(gong)油(you)(you)的(de)(de)(de)液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)箱(xiang)，在每(mei)次啟動(dong)機(ji)器(qi)后(hou)(hou)，必須等液(ye)(ye)(ye)(ye)壓(ya)(ya)漬箱(xiang)達到使用(yong)氣(qi)壓(ya)(ya)后(hou)(hou)，才能(neng)操(cao)作機(ji)械。直軸(zhou)斜盤式柱塞(sai)泵分為壓(ya)(ya)力供(gong)油(you)(you)型的(de)(de)(de)自(zi)吸油(you)(you)型兩種。壓(ya)(ya)力供(gong)油(you)(you)型液(ye)(ye)(ye)(ye)壓(ya)(ya)泵大都(dou)采用(yong)有(you)氣(qi)壓(ya)(ya)的(de)(de)(de)油(you)(you)箱(xiang)，也有(you)液(ye)(ye)(ye)(ye)壓(ya)(ya)泵本身帶有(you)補油(you)(you)分泵向液(ye)(ye)(ye)(ye)壓(ya)(ya)泵進油(you)(you)口提(ti)供(gong)壓(ya)(ya)力油(you)(you)的(de)(de)(de)。自(zi)吸油(you)(you)型液(ye)(ye)(ye)(ye)壓(ya)(ya)泵的(de)(de)(de)自(zi)吸油(you)(you)能(neng)力很強，無需外力供(gong)油(you)(you)。對(dui)于自(zi)吸油(you)(you)型柱塞(sai)泵，液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)箱(xiang)內(nei)的(de)(de)(de)油(you)(you)液(ye)(ye)(ye)(ye)不(bu)得低于油(you)(you)標下限，要(yao)保持足夠數量的(de)(de)(de)液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)。液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)的(de)(de)(de)清潔度越(yue)高，液(ye)(ye)(ye)(ye)壓(ya)(ya)泵的(de)(de)(de)使用(yong)壽命越(yue)長。 威格士柱塞泵工作流程： 威格士柱(zhu)塞(sai)(sai)(sai)泵(beng)柱(zhu)塞(sai)(sai)(sai)往(wang)復運動(dong)總行程(cheng)L是(shi)不(bu)變(bian)(bian)的(de)(de)，由凸(tu)(tu)輪(lun)的(de)(de)升程(cheng)決定。柱(zhu)塞(sai)(sai)(sai)每循環的(de)(de)供(gong)(gong)(gong)(gong)油(you)量大小取(qu)決于供(gong)(gong)(gong)(gong)油(you)行程(cheng),供(gong)(gong)(gong)(gong)油(you)行程(cheng)不(bu)受凸(tu)(tu)輪(lun)軸控制是(shi)可(ke)變(bian)(bian)的(de)(de)。供(gong)(gong)(gong)(gong)油(you)開始時刻不(bu)隨供(gong)(gong)(gong)(gong)油(you)行程(cheng)的(de)(de)變(bian)(bian)化而變(bian)(bian)化。轉動(dong)柱(zhu)塞(sai)(sai)(sai)可(ke)改變(bian)(bian)供(gong)(gong)(gong)(gong)油(you)終(zhong)了(le)時刻，從而改變(bian)(bian)供(gong)(gong)(gong)(gong)油(you)量。柱(zhu)塞(sai)(sai)(sai)泵(beng)工作(zuo)時，在噴油(you)泵(beng)凸(tu)(tu)輪(lun)軸上的(de)(de)凸(tu)(tu)輪(lun)與柱(zhu)塞(sai)(sai)(sai)彈簧的(de)(de)作(zuo)用下，迫使柱(zhu)塞(sai)(sai)(sai)作(zuo)上、下往(wang)復運動(dong)，從而完成(cheng)泵(beng)油(you)任務，泵(beng)油(you)過程(cheng)可(ke)分為以下三個(ge)階段(duan)。 進油過程 當凸(tu)輪(lun)的凸(tu)起部(bu)分轉(zhuan)過去后(hou)，在(zai)彈簧力的作用下(xia)，柱(zhu)塞向下(xia)運動(dong)，柱(zhu)塞上部(bu)空間（稱為泵(beng)油(you)(you)(you)室）產生真空度，當柱(zhu)塞上端面把柱(zhu)塞套上的進(jin)油(you)(you)(you)孔打開后(hou)，充(chong)滿在(zai)油(you)(you)(you)泵(beng)上體油(you)(you)(you)道內的柴油(you)(you)(you)經(jing)油(you)(you)(you)孔進(jin)入(ru)泵(beng)油(you)(you)(you)室，柱(zhu)塞運動(dong)到(dao)下(xia)止點(dian)，進(jin)油(you)(you)(you)結(jie)束(shu)。 供油過程 當凸輪軸轉到(dao)凸輪的(de)(de)凸起部(bu)分頂(ding)起滾輪體時，柱(zhu)塞(sai)彈(dan)簧被壓(ya)(ya)縮(suo)，柱(zhu)塞(sai)向上(shang)運動，燃油(you)(you)(you)(you)(you)(you)受(shou)壓(ya)(ya)，一(yi)(yi)部(bu)分燃油(you)(you)(you)(you)(you)(you)經油(you)(you)(you)(you)(you)(you)孔(kong)流回(hui)噴油(you)(you)(you)(you)(you)(you)泵上(shang)體油(you)(you)(you)(you)(you)(you)腔(qiang)。當柱(zhu)塞(sai)頂(ding)面遮(zhe)住套(tao)筒(tong)上(shang)進(jin)油(you)(you)(you)(you)(you)(you)孔(kong)的(de)(de)上(shang)緣時，由于柱(zhu)塞(sai)和套(tao)筒(tong)的(de)(de)配(pei)合間隙很小（0.0015-0.0025mm）使柱(zhu)塞(sai)頂(ding)部(bu)的(de)(de)泵油(you)(you)(you)(you)(you)(you)室成為一(yi)(yi)個(ge)密封油(you)(you)(you)(you)(you)(you)腔(qiang)，柱(zhu)塞(sai)繼續上(shang)升，泵油(you)(you)(you)(you)(you)(you)室內(nei)的(de)(de)油(you)(you)(you)(you)(you)(you)壓(ya)(ya)迅(xun)速升高(gao)，泵油(you)(you)(you)(you)(you)(you)壓(ya)(ya)力>出(chu)(chu)油(you)(you)(you)(you)(you)(you)閥(fa)彈(dan)簧力+高(gao)壓(ya)(ya)油(you)(you)(you)(you)(you)(you)管(guan)剩(sheng)余壓(ya)(ya)力時，推開出(chu)(chu)油(you)(you)(you)(you)(you)(you)閥(fa)，高(gao)壓(ya)(ya)柴油(you)(you)(you)(you)(you)(you)經出(chu)(chu)油(you)(you)(you)(you)(you)(you)閥(fa)進(jin)入高(gao)壓(ya)(ya)油(you)(you)(you)(you)(you)(you)管(guan)，通過噴油(you)(you)(you)(you)(you)(you)器(qi)噴入燃燒(shao)室。 回油過程 柱(zhu)塞向上(shang)供油(you)，當(dang)上(shang)行(xing)到柱(zhu)塞上(shang)的(de)(de)斜槽（停供邊）與套(tao)筒(tong)上(shang)的(de)(de)回油(you)孔(kong)相通時，泵油(you)室(shi)低壓(ya)(ya)油(you)路便與柱(zhu)塞頭部(bu)(bu)的(de)(de)中孔(kong)和徑(jing)向孔(kong)及斜槽溝(gou)通，油(you)壓(ya)(ya)驟(zou)然(ran)下降，出油(you)閥在彈簧(huang)力(li)的(de)(de)作用(yong)下迅速關閉，停止供油(you)。此(ci)后(hou)柱(zhu)塞還要上(shang)行(xing)，當(dang)凸輪的(de)(de)凸起部(bu)(bu)分轉過去后(hou)，在彈簧(huang)的(de)(de)作用(yong)下，柱(zhu)塞又下行(xing)。此(ci)時便開始了下一個循環。 柱塞(sai)泵以(yi)一(yi)(yi)(yi)個柱塞(sai)為原理(li)介紹，一(yi)(yi)(yi)個柱塞(sai)泵上(shang)有兩個單向(xiang)(xiang)閥，并且方(fang)向(xiang)(xiang)相反(fan)，柱塞(sai)向(xiang)(xiang)一(yi)(yi)(yi)個方(fang)向(xiang)(xiang)運(yun)(yun)動(dong)時(shi)缸內(nei)出現負壓，這時(shi)一(yi)(yi)(yi)個單向(xiang)(xiang)閥打開液(ye)體(ti)被(bei)吸(xi)入(ru)缸內(nei)，柱塞(sai)向(xiang)(xiang)另(ling)一(yi)(yi)(yi)個方(fang)向(xiang)(xiang)運(yun)(yun)動(dong)時(shi)，將液(ye)體(ti)壓縮(suo)后(hou)另(ling)一(yi)(yi)(yi)個單向(xiang)(xiang)閥被(bei)打開，被(bei)吸(xi)入(ru)缸內(nei)的(de)液(ye)體(ti)被(bei)排出。這種工(gong)作方(fang)式(shi)連(lian)續運(yun)(yun)動(dong)后(hou)就形成了連(lian)續供油 。 VICKERS柱(zhu)塞泵的特(te)點： 【1】VICKERS柱塞(sai)泵(beng)具有額定壓(ya)力高、結構緊湊、效率(lv)高和流(liu)量調節(jie)方便等優點。 【2】 VICKERS柱(zhu)塞(sai)泵是利(li)用與(yu)傳動軸平(ping)行(xing)的柱(zhu)塞(sai)在柱(zhu)塞(sai)孔內往復運動所(suo)產生的容積變(bian)化來進行(xing)工作的。由于(yu)柱(zhu)塞(sai)和柱(zhu)塞(sai)孔都是圓(yuan)形零件，加工時可以達到很高(gao)的精(jing)度配合，因此(ci)具有容積效率高(gao)，運轉平(ping)穩，流量均勻性好，噪聲低，工作壓(ya)力(li)高(gao)等優點，但對液(ye)壓(ya)油的污染(ran)較(jiao)敏感，結構較(jiao)復雜，造(zao)價較(jiao)高(gao)。 【3】柱塞(sai)泵依靠柱塞(sai)在(zai)缸體(ti)中(zhong)往(wang)復運動，使密封工作容腔的(de)(de)容積發生(sheng)變(bian)化來實現吸(xi)油、壓(ya)油。大金柱塞(sai)泵，柱塞(sai)泵，VICKERS柱塞(sai)泵被廣泛應(ying)用于高壓(ya)、大流量(liang)和流量(liang)需(xu)要(yao)調節的(de)(de)場合，諸如(ru)液壓(ya)機、工程機械和船舶中(zhong)。
