VICKERS威格士柱塞
徑向柱塞泵泵分類及工作原理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的,而定于的zui大偏心距為5—9mm(根據排量大小不同),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。
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往復運動所產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。
美國威格士vickers軸向柱塞泵一般都由缸體、配油盤、柱塞和斜盤等主要零件組成。缸體內有多個柱塞,柱塞是軸向排列的,即柱塞的中心線平行于傳動軸的軸線,因此稱它為軸向柱塞泵。但它又不同于往復式柱塞泵,因為它的柱塞不僅在泵缸內做往復運動,而且柱塞和泵缸與斜盤相對有旋轉運動。柱塞以一球形端頭與斜盤接觸。在配油盤上有高低壓月形溝槽,它們彼此由隔墻隔開,保證一定的密封性,它們分別與泵的進油口和出油口連通。斜盤的軸線與缸體軸線之間有一傾斜角度。
美國威格士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)生變化來實現吸油、壓油。柱塞泵具有額定壓力高、結構緊湊、效率高和流量調節(jié)方便等優(yōu)點,被廣泛應用于高壓、大流量和流量需要調節(jié)的場合,諸如液壓機、工程機械和船舶中。柱塞泵是往復泵的一種,屬于體積泵,其柱塞靠泵軸的偏心轉動驅動,往復運動,其吸入和排出閥都是單向閥。當柱塞外拉時,工作室內壓力降低,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。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,通過調節(jié)斜盤的傾角可改變泵的排量。

威格士vickers柱塞泵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、回油孔,均與泵上體內低壓油腔相通,柱塞套裝入泵上體后,應用定位螺釘定位。柱塞頭部斜槽的位置不同,改變供油量的方法也不同。 出油閥和出油閥座也是一對精密偶件,配對研磨后不能互換,其配合間隙為0.01mm 。 出油閥是一個單向閥,在彈簧壓力作用下,閥上部圓錐面與閥座嚴密配合,其作用是在停供時,將高壓油管與柱塞上端空腔隔絕,防止高壓油管內的油倒流入噴油泵內。出油閥的下部呈十字斷面,既能導向,又能通過柴油。出油閥的錐面下有一個小的圓柱面,稱為減壓環(huán)帶,其作用是在供油終了時,使高壓油管內的油壓迅速下降,避免噴孔處產生滴油現象。當環(huán)帶落入閥座內時則使上方容積很快增大,壓力迅速減小,停噴迅速。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、回油孔,均與泵上體內低壓油腔相通,柱塞套裝入泵上體后,應用定位螺釘定位。
