VICKERS柱塞泵PVH074R13AA10B25200000結(jié)構(gòu)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(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(wèn)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(zhǎng)壽命、易維護(hù)、高效率等優(yōu)點(diǎn)。
廣泛應(yīng)用于注塑機(jī)，油壓機(jī)、工程機(jī)械、塑膠機(jī)械、制鞋機(jī)械、壓鑄機(jī)械、冶金機(jī)械、礦山機(jī)械、油田機(jī)械、船舶行業(yè)以及各種生產(chǎn)線適用油壓機(jī)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(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(wú)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)。

vickers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(lái)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。
