VICKERS柱塞泵柱塞往復(fù)運動總行程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刻，從而改變供油量。柱塞泵工作時，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)運動，從而完成泵油任務(wù)。
VICKERS柱塞泵的機械分類：
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，加工時可以達(dá)到很高的精度配合，因此容積效率高，運轉(zhuǎn)平穩(wěn)，流量均勻性好，噪聲低，工作壓力高等優(yōu)點，但對液壓油的污染較敏感，結(jié)構(gòu)較復(fù)雜，造價較高。
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，無需外力供油。靠氣壓供油的液壓油箱，在每次啟動機器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機械。如液壓油箱的氣壓不足時就擔(dān)任機器，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。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，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。且變量機構(gòu)設(shè)計為高壓操縱，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，在每次啟動機器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機械。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，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。
威格士柱塞泵的特電和優(yōu)點：
- 泵的壽命長
- 泵的噪聲低
- 進(jìn)口和出口的壓力表
- 接口和可調(diào)整的zui大
- 排量擋塊-標(biāo)準(zhǔn)
- 壓力脈動小得驚人，僅4%
- 安裝和使用成本低
- 維護(hù)簡單
- 設(shè)備設(shè)計的靈活性強
- 體積小,節(jié)省空間
- 提升無泄漏系統(tǒng)設(shè)計
