VICKERS柱塞泵工作原理： VICKERS柱塞泵是液壓系統(tǒng)的一個(gè)重要裝置。它依靠柱塞在缸體中往復(fù)運(yùn)動(dòng)，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(dòng)，因此，它的運(yùn)動(dòng)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變量柱塞泵，可以串聯(lián)齒輪泵。由齒輪泵與柱塞泵共同構(gòu)成的油源系統(tǒng)，可以控制整體的功率曲線，使得恒功率控制不再局限于對(duì)單個(gè)油泵的控制，而是整個(gè)系統(tǒng)。 VICKERS變量柱塞泵工作狀態(tài)： VICKERS變量柱塞泵其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時(shí)，工作室內(nèi)壓力降低，出口閥關(guān)閉，低于進(jìn)口壓力時(shí)，進(jìn)口閥打開，液體進(jìn)入；柱塞內(nèi)推時(shí)，工作室壓力升高，進(jìn)口閥關(guān)閉，高于出口壓力時(shí)，出口閥打開，液體排出。 帶滑靴結(jié)構(gòu)的軸向柱塞泵是目前使用zui廣泛的軸向柱塞泵，安放在缸體中的柱塞通過滑靴與斜盤相接觸，當(dāng)傳動(dòng)軸帶動(dòng)缸體旋轉(zhuǎn)時(shí)，斜盤將柱塞從缸體中拉出或推回，完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機(jī)構(gòu)用來改變斜盤的傾角，通過調(diào)節(jié)斜盤的傾角可改變泵的排量。 VICKERS柱塞泵柱塞往復(fù)運(yùn)動(dòng)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(dòng)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(dòng)，從而完成泵油任務(wù)。 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(dòng)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(dòng)軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動(dòng)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(duì)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(dòng)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(huì)對(duì)液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象，出會(huì)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(zhǎng)、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(dòng)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(duì)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(zhǎng)。 威格士柱塞泵的特電和優(yōu)點(diǎn)： 【1】泵的壽命長(zhǎng)
【2】泵的噪聲低
【3】進(jìn)口和出口的壓力表
【4】接口和可調(diào)整的zui大
