VICKERS柱塞泵PVH074R13AA10B25200000結構原理：

威格士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。由于徑向泵結構上的特點，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。且變量機構設計為高壓操縱，由控制閥進行控制。故該泵的響應速度快。徑向結構設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。

VICKERS威格士油泵:具有高壓、噪音低、長壽命、易維護、高效率等優(yōu)點。
廣泛應用于注塑機，油壓機、工程機械、塑膠機械、制鞋機械、壓鑄機械、冶金機械、礦山機械、油田機械、船舶行業(yè)以及各種生產(chǎn)線適用油壓機械零件。

威格士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。

vickers軸向柱塞泵是活塞或柱塞的往復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)往復運動所產(chǎn)生的容積變化來進行工作的。由于柱塞和柱塞孔都是圓形零件，加工時可以達到很高的精度配合，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，結構較復雜，造價較高。
