VICKERS威格士柱塞泵美國進口現(xiàn)貨 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(jié)構(gòu)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(gòu)設(shè)計為高壓操縱,由控制閥進行控制。故該泵的響應(yīng)速度快。徑向結(jié)構(gòu)設(shè)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(fù)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(fù)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(dá)到很高的精度配合,因此容積效率高,運轉(zhuǎn)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(jié)構(gòu)較復(fù)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(nèi)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(fù)式柱塞泵,因為它的柱塞不僅在泵缸內(nèi)做往復(fù)運動,而且柱塞和泵缸與斜盤相對有旋轉(zhuǎn)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(fù)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,被廣泛應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場合,諸如液壓機、工程機械和船舶中。柱塞泵是往復(fù)泵的一種,屬于體積泵,其柱塞靠泵軸的偏心轉(zhuǎn)動驅(qū)動,往復(fù)運動,其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時,工作室內(nèi)壓力降低,出口閥關(guān)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(guān)閉,高于出口壓力時,出口閥打開,液體排出。當(dāng)傳動軸帶動缸體旋轉(zhuǎn)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(gòu)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。 威格士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(fù)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(dá)到很高的精度配合,因此容積效率高,運轉(zhuǎn)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(jié)構(gòu)較復(fù)雜,造價較高。柱塞和柱塞套是一對精密偶件,經(jīng)配對研磨后不能互換,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 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(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。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(yán)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(nèi)的油倒流入噴油泵內(nèi)。出油閥的下部呈十字?jǐn)嗝妫饶軐?dǎo)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(nèi)的油壓迅速下降,避免噴孔處產(chǎn)生滴油現(xiàn)象。當(dāng)環(huán)帶落入閥座內(nèi)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(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。 柱塞頭部斜槽的位置不同,改變供油量的方法也不同。出油閥是一個單向閥,在彈簧壓力作用下,閥上部圓錐面與閥座嚴(yán)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(nèi)的油倒流入噴油泵內(nèi)。出油閥的下部呈十字?jǐn)嗝?,既能?dǎo)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(nèi)的油壓迅速下降,避免噴孔處產(chǎn)生滴油現(xiàn)象。當(dāng)環(huán)帶落入閥座內(nèi)時則使上方容積很快增大,壓力迅速減小,停噴迅速。 VICKERS威格士柱塞泵美國進口現(xiàn)貨 PVH074R01AA10A25000000100100010A PVH74C-RF-1S-10-C25-31 PVH074R01AA10B25200000100100010A PVH74C-RF-1S-10-C25V-31 PVH074R01AA10A250000001001AA010A PVH74C-RF-1S-11-C25-31 PVH074R01AA10B252000001001AA010A PVH74C-RF-1S-11-C25V-31 PVH074R02AA10A25000000100100010A PVH74C-RF-2S-10-C25-31 PVH074R02AA10B25200000100100010A PVH74C-RF-2S-10-C25V-31 PVH074R02AA10B252000001001AA010A PVH74C-RF-2S-11-C25V-31 PVH074R01AA10A25000000200100010A PVH74C-RSF-1S-10-C25-31 PVH074R01AA10B25200000200100010A PVH74C-RSF-1S-10-C25V-31 PVH074R01AA10A250000002001AA010A PVH74C-RSF-1S-11-C25-31 PVH074R02AA10A25000000200100010A PVH74C-RSF-2S-10-C25-31 PVH074R02AA10B25200000200100010A PVH74C-RSF-2S-10-C25V-31 PVH074R01AA10A250000001001AB010A PVH74QIC-RF-1S-10-C25-31 PVH074R01AA10B252000001001AB010A PVH74QIC-RF-1S-10-C25V-31 PVH074R01AA10A250000001001AE010A PVH74QIC-RF-1S-11-C25-31 PVH074R01AA10B252000001001AE010A PVH74QIC-RF-1S-11-C25V-31 PVH074R02AA10A250000001001AB010A PVH74QIC-RF-2S-10-C25-31 PVH074R02AA10B252000001001AB010A PVH74QIC-RF-2S-10-C25V-31 PVH074R02AA10A250000001001AE010A PVH74QIC-RF-2S-11-C25-31 PVH074R02AA10B252000001001AE010A PVH74QIC-RF-2S-11-C25V-31 PVH074R01AB10A250000001001AB010A PVH74QIC-RM-1S-10-C25-31 PVH074R02AB10A250000001001AE010A PVH74QIC-RM-2S-11-C25-31 PVH074R01AA10A250000002001AB010A PVH74QIC-RSF-1S-10-C25-31 PVH074R01AA10B252000002001AB010A PVH74QIC-RSF-1S-10-C25V-31 PVH074R01AA10A250000002001AE010A PVH74QIC-RSF-1S-11-C25-31 PVH074R02AA10A250000002001AB010A PVH74QIC-RSF-2S-10-C25-31 PVH074R02AA10A250000002001AE010A PVH74QIC-RSF-2S-11-C25-31 PVH074R01AB10A250000002001AE010A PVH74QIC-RSM-1S-11-C25-31 VICKERS威格士PVH098型號.
