美國VICKERS變量柱塞泵PVH系列代理
威格士柱塞泵缸體鑲裝銅套的,可以采用更換銅套的方法安裝。首先把一組柱塞桿外徑修整到統(tǒng)一尺寸,再用1000#以上的砂紙拋光外徑。

詳細介紹

VICKERS柱塞泵工作原理

    VICKERS柱塞泵是液壓系統(tǒng)的一個重要裝置。它依靠柱塞在缸體中往復運動,使密封工作容腔的容積發(fā)生變化來實現(xiàn)吸油、壓油。柱塞在缸體中要往復運動,因此,它的運動量很大,在工作過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。通過研究,采用淬火熱處理可以滿足柱塞的技術要求。
 
美國威格士柱塞泵的產(chǎn)品分類

1.軸向柱塞泵
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。
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??繗鈮汗┯偷囊簤河拖洌诿看螁訖C器后,必須等液壓漬箱達到使用氣壓后,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.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。
4.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變量柱塞泵,可以串聯(lián)齒輪泵。由齒輪泵與柱塞泵共同構成的油源系統(tǒng),可以控制整體的功率曲線,使得恒功率控制不再局限于對單個油泵的控制,而是整個系統(tǒng)。

 VICKERS變量柱塞泵工作狀態(tài):

    VICKERS變量柱塞泵其吸入和排出閥都是單向閥。當柱塞外拉時,工作室內(nèi)壓力降低,出口閥關閉,低于進口壓力時,進口閥打開,液體進入;柱塞內(nèi)推時,工作室壓力升高,進口閥關閉,高于出口壓力時,出口閥打開,液體排出。 帶滑靴結構的軸向柱塞泵是目前使用zui廣泛的軸向柱塞泵,安放在缸體中的柱塞通過滑靴與斜盤相接觸,當傳動軸帶動缸體旋轉時,斜盤將柱塞從缸體中拉出或推回,完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機構用來改變斜盤的傾角,通過調(diào)節(jié)斜盤的傾角可改變泵的排量。

    VICKERS變量柱塞泵柱塞往復運動總行程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。轉動柱塞可改變供油終了時刻,從而改變供油量。
