VICKERS柱塞泵工作原理： VICKERS柱塞泵是(shi)液壓(ya)系(xi)統的(de)壹(yi)個重要裝(zhuang)置。它(ta)依靠柱塞在缸(gang)體中往復(fu)運(yun)動(dong)，使(shi)密封工作容(rong)腔的(de)容(rong)積發(fa)生(sheng)變(bian)化來(lai)實(shi)現(xian)吸油、壓(ya)油。柱塞在缸(gang)體中要往復(fu)運(yun)動(dong)，因此，它的(de)運(yun)動(dong)量很(hen)大(da)，在工作過(guo)程中需(xu)要承受巨大的(de)摩(mo)擦(ca)力(li)，因此，柱塞要求(qiu)高的硬度、耐(nai)磨(mo)性(xing)和使(shi)用(yong)壽命(ming)以(yi)及高的精度等(deng)。通(tong)過(guo)研究，采用淬(cui)火(huo)熱處理可以(yi)滿足(zu)柱塞的(de)技術要求(qiu)。
VICKERS變(bian)量柱塞泵，可以(yi)串(chuan)聯齒輪(lun)泵。由齒輪(lun)泵與(yu)柱塞泵共同構成的油源(yuan)系(xi)統，可以(yi)控制(zhi)整體的功率(lv)曲線(xian)，使(shi)得(de)恒功率(lv)控制(zhi)不再(zai)局(ju)限於對(dui)單個油泵的控制(zhi)，而(er)是(shi)整個系(xi)統。 VICKERS變(bian)量柱塞泵工作狀態(tai)： VICKERS變量柱塞泵其吸入(ru)和排(pai)出閥(fa)都(dou)是(shi)單向(xiang)閥(fa)。當柱塞外(wai)拉(la)時(shi)，工(gong)作室內(nei)壓力(li)降(jiang)低(di)，出口閥(fa)關(guan)閉，低(di)於進(jin)口(kou)壓力(li)時(shi)，進(jin)口(kou)閥(fa)打開，液體進(jin)入(ru)；柱塞內(nei)推(tui)時(shi)，工(gong)作(zuo)室壓(ya)力(li)升(sheng)高，進(jin)口(kou)閥(fa)關(guan)閉，高於出口壓力(li)時(shi)，出口閥(fa)打開，液體排出。 帶滑(hua)靴(xue)結構(gou)的(de)軸(zhou)向(xiang)柱塞泵是(shi)目前使用zui廣泛的軸(zhou)向(xiang)柱塞泵，安放(fang)在缸(gang)體中的(de)柱塞通(tong)過(guo)滑(hua)靴(xue)與(yu)斜(xie)盤(pan)相接觸，當傳動(dong)軸(zhou)帶動(dong)缸(gang)體旋轉(zhuan)時(shi)，斜(xie)盤(pan)將(jiang)柱塞從缸(gang)體中拉(la)出或推(tui)回(hui)，完(wan)成(cheng)吸排油過(guo)程。柱塞與(yu)缸(gang)孔(kong)組(zu)成(cheng)的工作容(rong)腔中(zhong)的油液(ye)通(tong)過(guo)配油盤(pan)分別與(yu)泵的吸、排油腔(qiang)相通(tong)。變量機(ji)構用來(lai)改(gai)變斜(xie)盤(pan)的傾角(jiao)，通(tong)過(guo)調(tiao)節斜盤(pan)的傾角(jiao)可改(gai)變泵的排量。 VICKERS柱塞泵柱塞往復(fu)運(yun)動(dong)總(zong)行(xing)程L是(shi)不變(bian)的，由(you)凸輪(lun)的升程決定(ding)。柱塞每(mei)循(xun)環的供(gong)油量大(da)小取(qu)決於供(gong)油行(xing)程,供(gong)油行(xing)程不受凸輪(lun)軸(zhou)控制(zhi)是(shi)可變的(de)。供(gong)油開始(shi)時刻(ke)不(bu)隨供(gong)油行(xing)程的變化而(er)變(bian)化。轉(zhuan)動(dong)柱塞可改(gai)變供(gong)油終(zhong)了(le)時刻，從而(er)改(gai)變供(gong)油量。柱塞泵工作時，在噴油泵凸輪(lun)軸(zhou)上(shang)的(de)凸輪(lun)與(yu)柱塞彈(dan)簧(huang)的(de)作(zuo)用下(xia)，迫(po)使(shi)柱塞作(zuo)上(shang)、下(xia)往復(fu)運(yun)動(dong)，從而(er)完(wan)成泵油任(ren)務(wu)。 VICKERS柱塞泵的機械分(fen)類(lei)： ①軸(zhou)向(xiang)柱塞泵 軸(zhou)向(xiang)柱塞泵是(shi)活(huo)塞(sai)或柱塞的(de)往復(fu)運(yun)動(dong)方(fang)向(xiang)與(yu)缸(gang)體中心(xin)軸(zhou)平行(xing)的柱塞泵。軸(zhou)向(xiang)柱塞泵是(shi)利(li)用(yong)與(yu)傳(chuan)動(dong)軸(zhou)平行(xing)的柱塞在柱塞孔(kong)內(nei)往復(fu)運(yun)動(dong)所產生(sheng)的(de)容(rong)積變(bian)化來(lai)進(jin)行(xing)工作的(de)。由(you)於柱塞和柱塞孔(kong)都(dou)是(shi)圓形(xing)零件，加工時(shi)可以(yi)達到(dao)很(hen)高的精度配合，因此容(rong)積效率高，運轉(zhuan)平(ping)穩(wen)，流量均(jun)勻(yun)性好，噪(zao)聲(sheng)低(di)，工(gong)作壓力(li)高等優點(dian)，但(dan)對(dui)液(ye)壓(ya)油的(de)汙染較(jiao)敏感(gan)，結構(gou)較(jiao)復(fu)雜(za)，造(zao)價(jia)較高。 ②直(zhi)軸(zhou)斜盤(pan)式柱塞泵 直(zhi)軸(zhou)斜盤(pan)式柱塞泵分為壓(ya)力(li)供(gong)油型的自吸油型兩種。壓(ya)力(li)供(gong)油型液壓泵大都(dou)采用有氣(qi)壓(ya)的(de)油箱(xiang)，也有液(ye)壓(ya)泵本身帶有補(bu)油分(fen)泵向(xiang)液(ye)壓(ya)泵進(jin)油口(kou)提(ti)供(gong)壓(ya)力(li)油的(de)。自(zi)吸油型液壓泵的自吸油能力(li)很(hen)強，無需(xu)外(wai)力(li)供(gong)油。靠(kao)氣(qi)壓(ya)供(gong)油的(de)液(ye)壓油箱(xiang)，在每次啟(qi)動(dong)機(ji)器(qi)後，必須(xu)等(deng)液(ye)壓(ya)漬(zi)箱(xiang)達到使(shi)用(yong)氣(qi)壓(ya)後，才能操(cao)作機(ji)械。如(ru)液壓油箱(xiang)的氣(qi)壓(ya)不(bu)足時就(jiu)擔(dan)任(ren)機(ji)器(qi)，會對(dui)液(ye)壓(ya)泵內(nei)的與(yu)滑(hua)鞭造(zao)成(cheng)拉脫現(xian)象(xiang)，出會造(zao)成(cheng)泵體內(nei)回(hui)程板與(yu)壓(ya)板的非正(zheng)常磨(mo)損(sun)。 ③徑(jing)向(xiang)柱塞泵 徑(jing)向(xiang)柱塞泵可分為閥(fa)配流與(yu)軸(zhou)配流兩(liang)大(da)類(lei)。閥(fa)配流徑(jing)向(xiang)柱塞泵存(cun)在故(gu)障(zhang)率高、效率低(di)等(deng)缺(que)點(dian)。上(shang)70、80年(nian)代發(fa)展(zhan)的軸(zhou)配流徑(jing)向(xiang)柱塞泵克服了(le)閥(fa)配流徑(jing)向(xiang)柱塞泵的不足。由(you)於徑(jing)向(xiang)泵結構(gou)上(shang)的(de)特點(dian)，陜(shan)定(ding)了(le)軸(zhou)配流徑(jing)向(xiang)柱塞泵比(bi)軸(zhou)向(xiang)柱塞泵耐(nai)沖擊(ji)、壽命(ming)長(chang)、控(kong)制(zhi)精度(du)高。變量行(xing)程短泵的變量是(shi)在變量柱塞和限(xian)位柱塞作(zuo)用下(xia)，改(gai)變定(ding)子的偏(pian)心(xin)距(ju)實(shi)現(xian)的，而(er)定(ding)於的(de)zui大偏(pian)心(xin)距(ju)為5—9mm(根(gen)據(ju)排(pai)量大(da)小不(bu)同)，變量行(xing)程很(hen)短(duan)。且變量機(ji)構設(she)計(ji)為高壓操(cao)縱(zong)，由(you)控制(zhi)閥(fa)進(jin)行(xing)控制(zhi)。故(gu)該(gai)泵的響(xiang)應速度(du)快(kuai)。徑(jing)向(xiang)結構(gou)設(she)計(ji)克(ke)服(fu)了(le)如軸(zhou)向(xiang)柱塞泵滑(hua)靴(xue)偏(pian)磨(mo)的(de)問題(ti)。使其(qi)抗(kang)沖擊(ji)能力(li)大(da)幅(fu)度提(ti)高。 ④液壓柱塞泵 液壓柱塞泵靠氣(qi)壓(ya)供(gong)油的(de)液(ye)壓油箱(xiang)，在每次啟(qi)動(dong)機(ji)器(qi)後，必須(xu)等(deng)液(ye)壓(ya)漬(zi)箱(xiang)達到使(shi)用(yong)氣(qi)壓(ya)後，才能操(cao)作機(ji)械。直(zhi)軸(zhou)斜盤(pan)式柱塞泵分為壓(ya)力(li)供(gong)油型的自吸油型兩種。壓(ya)力(li)供(gong)油型液壓泵大都(dou)采用有氣(qi)壓(ya)的(de)油箱(xiang)，也有液(ye)壓(ya)泵本身帶有補(bu)油分(fen)泵向(xiang)液(ye)壓(ya)泵進(jin)油口(kou)提(ti)供(gong)壓(ya)力(li)油的(de)。自(zi)吸油型液壓泵的自吸油能力(li)很(hen)強，無需(xu)外(wai)力(li)供(gong)油。對(dui)於自(zi)吸油型柱塞泵，液壓油箱(xiang)內(nei)的油液(ye)不(bu)得(de)低(di)於油標(biao)下(xia)限，要保持足夠(gou)數量的(de)液壓油。液(ye)壓(ya)油的(de)清潔度越(yue)高，液壓泵的使用壽(shou)命(ming)越(yue)長(chang)。 威格士(shi)柱塞泵的特電(dian)和優(you)點(dian)： 【1】泵的壽命(ming)長(chang)
