VICKERS柱塞泵工作原理：
VICKERS柱塞泵是液壓系統(tǒng)的一個重要裝置。它依靠柱塞在缸體中往復(fù)運(yùn)動，使密封工作容腔的容積發(fā)生變化來實(shí)現(xiàn)吸油、壓油。柱塞在缸體中要往復(fù)運(yùn)動，因此，它的運(yùn)動量很大，在工作過程中需要承受巨大的摩擦力，因此，柱塞要求高的硬度、耐磨性和使用壽命以及高的精度等。通過研究，采用淬火熱處理可以滿足柱塞的技術(shù)要求。
VICKERS柱塞泵的機(jī)械分類：
①軸向柱塞泵
軸向柱塞泵是活塞或柱塞的往復(fù)運(yùn)動方向與缸體中心軸平行的柱塞泵。軸向柱塞泵是利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件，加工時(shí)可以達(dá)到很高的精度配合，因此容積效率高，運(yùn)轉(zhuǎn)平穩(wěn)，流量均勻性好，噪聲低，工作壓力高等優(yōu)點(diǎn)，但對液壓油的污染較敏感，結(jié)構(gòu)較復(fù)雜，造價(jià)較高。
②直軸斜盤式柱塞泵
直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng)，無需外力供油?？繗鈮汗┯偷囊簤河拖?，在每次啟動機(jī)器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。如液壓油箱的氣壓不足時(shí)就擔(dān)任機(jī)器，會對液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象，出會造成泵體內(nèi)回程板與壓板的非正常磨損。
③徑向柱塞泵
徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高、效率低等缺點(diǎn)。上70、80年代發(fā)展的軸配流徑向柱塞泵克服了閥配流徑向柱塞泵的不足。由于徑向泵結(jié)構(gòu)上的特點(diǎn)，陜定了軸配流徑向柱塞泵比軸向柱塞泵耐沖擊、壽命長、控制精度高。變量行程短泵的變量是在變量柱塞和限位柱塞作用下，改變定子的偏心距實(shí)現(xiàn)的，而定于的zui大偏心距為5—9mm(根據(jù)排量大小不同)，變量行程很短。且變量機(jī)構(gòu)設(shè)計(jì)為高壓操縱，由控制閥進(jìn)行控制。故該泵的響應(yīng)速度快。徑向結(jié)構(gòu)設(shè)計(jì)克服了如軸向柱塞泵滑靴偏磨的問題。使其抗沖擊能力大幅度提高。
④液壓柱塞泵
液壓柱塞泵靠氣壓供油的液壓油箱，在每次啟動機(jī)器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng)，無需外力供油。對于自吸油型柱塞泵，液壓油箱內(nèi)的油液不得低于油標(biāo)下限，要保持足夠數(shù)量的液壓油。液壓油的清潔度越高，液壓泵的使用壽命越長。
威格士柱塞泵工作流程：
威格士柱塞泵柱塞往復(fù)運(yùn)動總行程L是不變的，由凸輪的升程決定。柱塞每循環(huán)的供油量大小取決于供油行程,供油行程不受凸輪軸控制是可變的。供油開始時(shí)刻不隨供油行程的變化而變化。轉(zhuǎn)動柱塞可改變供油終了時(shí)刻，從而改變供油量。柱塞泵工作時(shí)，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復(fù)運(yùn)動，從而完成泵油任務(wù)，泵油過程可分為以下三個階段。
進(jìn)油過程
當(dāng)凸輪的凸起部分轉(zhuǎn)過去后，在彈簧力的作用下，柱塞向下運(yùn)動，柱塞上部空間（稱為泵油室）產(chǎn)生真空度，當(dāng)柱塞上端面把柱塞套上的進(jìn)油孔打開后，充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進(jìn)入泵油室，柱塞運(yùn)動到下止點(diǎn)，進(jìn)油結(jié)束。
供油過程
當(dāng)凸輪軸轉(zhuǎn)到凸輪的凸起部分頂起滾輪體時(shí)，柱塞彈簧被壓縮，柱塞向上運(yùn)動，燃油受壓，一部分燃油經(jīng)油孔流回噴油泵上體油腔。當(dāng)柱塞頂面遮住套筒上進(jìn)油孔的上緣時(shí)，由于柱塞和套筒的配合間隙很小（0.0015-0.0025mm）使柱塞頂部的泵油室成為一個密封油腔，柱塞繼續(xù)上升，泵油室內(nèi)的油壓迅速升高，泵油壓力>出油閥彈簧力+高壓油管剩余壓力時(shí)，推開出油閥，高壓柴油經(jīng)出油閥進(jìn)入高壓油管，通過噴油器噴入燃燒室。
回油過程
柱塞向上供油，當(dāng)上行到柱塞上的斜槽（停供邊）與套筒上的回油孔相通時(shí)，泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通，油壓驟然下降，出油閥在彈簧力的作用下迅速關(guān)閉，停止供油。此后柱塞還要上行，當(dāng)凸輪的凸起部分轉(zhuǎn)過去后，在彈簧的作用下，柱塞又下行。此時(shí)便開始了下一個循環(huán)。
柱塞泵以一個柱塞為原理介紹，一個柱塞泵上有兩個單向閥，并且方向相反，柱塞向一個方向運(yùn)動時(shí)缸內(nèi)出現(xiàn)負(fù)壓，這時(shí)一個單向閥打開液體被吸入缸內(nèi)，柱塞向另一個方向運(yùn)動時(shí)，將液體壓縮后另一個單向閥被打開，被吸入缸內(nèi)的液體被排出。這種工作方式連續(xù)運(yùn)動后就形成了連續(xù)供油 。
