美國(guó)威格士柱塞泵的產(chǎn)品分類(lèi) 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(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。
2.直軸斜盤(pán)式柱塞泵
直軸斜盤(pán)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?？繗鈮汗┯偷囊簤河拖洌诿看螁?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.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(pán)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)。
4.徑向柱塞泵
徑向柱塞泵可分為閥配流與軸配流兩大類(lèi)。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柱塞泵420系列簡(jiǎn)介： VICKERS柱塞泵420系列工程機(jī)械泵是開(kāi)式回路，軸向柱塞設(shè)計(jì)，提供許多種控制器使泵具有和每一種用途相匹配的能力。泵控制器的效率允許降低了對(duì)系統(tǒng)冷卻的要求。允許采用更小巧和并不昂貴的設(shè)計(jì)，換句話(huà)說(shuō)，保持制冷量不變，而系統(tǒng)的流量增大，于是改善了性能和用戶(hù)的滿(mǎn)意度。 VICKERS柱塞泵420系列經(jīng)過(guò)嚴(yán)格考驗(yàn)的旋轉(zhuǎn)系允許泵的連續(xù)工作壓力至 280bar (4000 psi)，間歇工作壓力至 320 bar (4600 psi)，而且維護(hù)成本低。重型軸承和剛性驅(qū)動(dòng)軸使泵的B10軸承壽命在額定工程機(jī)械工況下達(dá)到 3320 小時(shí)，降低使用成本，延長(zhǎng)使用壽命。 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(lái)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(guò)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(guò)研究，采用淬火熱處理可以滿(mǎn)足柱塞的技術(shù)要求。 美國(guó)威格士柱塞泵ADU系列常見(jiàn)產(chǎn)品型號(hào)如下：
