美國威格士產(chǎn)品詳解:
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。
VICKERS威格士直軸斜盤式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。
VICKERS柱塞泵的泵油機(jī)構(gòu)包括兩套精密偶件:柱塞(plunger)+柱塞套(barrel)構(gòu)成柱塞偶件(plunger and barrel assembly)(圖5-11)、出油閥(delivery valve)和出油閥座(delivery valve seat)構(gòu)成出油閥偶件(delivery valve assembly
VICKERS柱塞和柱塞套是一對(duì)精密偶件,經(jīng)配對(duì)研磨后不能互換,要求有高的精度和光潔度和好的耐磨性,其徑向間隙為0.002~0.003mm
VICKERS柱塞頭部圓柱面上切有斜槽,并通過徑向孔、軸向孔與頂部相通,其目的是改變循環(huán)供油量;柱塞套上制有進(jìn)、回油孔,均與泵上體內(nèi)低壓油腔相通,柱塞套裝入泵上體后,應(yīng)用定位螺釘定位。
VICKERS柱塞頭部斜槽的位置不同,改變供油量的方法也不同。
威格士柱塞泵是液壓系統(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。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高和流量調(diào)節(jié)方便等優(yōu)點(diǎn),被廣泛應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場(chǎng)合,諸如液壓機(jī)、工程機(jī)械和船舶中。VICKERS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,因此具有容積效率高,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。
