VICKERS上海銷售處/美國VICKERS威格士柱塞泵,美國VICKERS威格士柱塞泵分為軸向柱塞泵和徑向柱塞泵兩種代表性的結(jié)構(gòu)形式;因為徑向柱塞泵屬于一種新型的技術(shù)含量比較高的高效泵,跟著國產(chǎn)化的不斷加快,徑向柱塞泵必定會成為柱塞泵應用領(lǐng)域的重要組成部門。VICKERS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)往復運動所產(chǎn)生的容積變化來進行工作的。因為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(zhuǎn)平穩(wěn),流量平均性好,噪聲低,工作壓力高等長處,但對液壓油的污染較敏感,結(jié)構(gòu)較復雜,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,其目的是改變輪回供油量;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(nèi)的油倒流入噴油泵內(nèi)。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(nèi)的油壓迅速下降,避免噴孔處產(chǎn)生滴油現(xiàn)象。當環(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,其目的是改變輪回供油量;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,應用定位螺釘定位。威格士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(nèi)的油壓迅速下降,避免噴孔處產(chǎn)生滴油現(xiàn)象。當環(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上海銷售處/美國VICKERS威格士柱塞泵,美國VICKERS威格士柱塞泵結(jié)構(gòu)原理,威格士柱塞泵工作過程,VICKERS威格士柱塞泵特點,VICKERS威格士柱塞泵工作時,在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下,迫使柱塞作上、下往復運動,從而完成泵油任務,泵油過程可分為以下三個階段。VICKERS部分型號如下:4535V60A25-1AA-22R4535V60A25-1CC-22R4525V60A12-1AA-22R4525V60A12-1CC-22R2520V17A5-1AA-22R2520V17A5-1AA-22R2520V17A5 1BB22R2520V17A5 1CC22R2520V17A5 1DD22R2520V17A5 1AB22R2520V17A8 1AA22R2520V17A8 1BB22R2520V17A8 1CC22R2520V17A8 1CC22L2520V17A8 1CB22R2520V17A11 86DD22R2520V17A11 1DD22R2520V17A14 1AA22R2520V17A14 1CC22R2520V17A14 1CB22R2520V21A2 1AA22R2520V21A2 1CC22R2520V21A5 1AA22R2520V21A5 1CC22R2520V21A5 1DD22R2520V21A8 1AA22R2520V21A8 1BB22R2520V21A8 1CC22R2520V21A8 1DD22R2520V21A11 1AA22R2520V21A11 1BB22R2520V21A11 1CC22R2520V21A11-1AB22R2520V21A11-1DA22R2520V21A12 1AA22R2520V21A12 1BB22R2520V21A12 1CC22R2520V21A12 1DD22R2520V21A12 1CB22R2520V21A14 1AA22R2520V21A14 1DD22R2520V21A14-1AB22R2520V21A14 1AC22R2520V21A14 1AD22R2520V21A14 1CB22R2520VQH17A12-1DD20R2525V21A17 86DA22R3520V25A5 1AA22R3520V25A5 1CC22R3520V25A8-86CB22R3520V25A11 1BB22R3520V25A11 86AB22R3520V25A12 1AA22R3520V25A12 1CC22R3520V25A12-1DD22R3520V30A2 1CC22R3520V30A5 1DB22R3520V30A5 1DC22R20V5A 1C22R20V5A 1C22R20V5A 1D22R20V8A 1A22R20V8A 1C22R20V8A 1D22R20V8A-1C22L20V8A 151C22R20V11A 1A22R20V11A 1B22R20V11A 1C22R20V11A 1D22R20V11A 1A22L20V12A 1A22R20V12A 1D22R20VQ5A 1C3025V10A 1A22R25V10A-1C22R25V12A 1B22R25V12A 1C22R25V12A 1D22R25V12A-11A22R25V14A 1A22R25V14A 1B22R25V14A 1C22R25V14A 1D22R25V14A-1B22L25V14AF-1C22R25V14AM-1D22R25V17A 1A22R25V17A 1B22R25V17A 1C22R25V17A 1D22R25V17A 1A22L25V17A 11B22L25V21A 1A22R25V21A 1B22R25V21A 1C22R25V21A 1D22R25V21A 1A22L35V25A 1A22R35V25A 1B22R35V25A 1C22R35V25A 1D22R35V30A 1A22R35V30A 1B22R35V30A 1C22R3525V35A21-1BA22R3525V38A12-1BB-22R3525V38A14 11AA22R3525V38A17 1AA22R3525V38A17 1BB22R3525V38A17 1CC22R3525V38A17 1BA22R3525V38A17 1DA22R3525V38A21 1AA22R3525V38A21 1BB22R3525V38A21 1CC22R3525V38A21-1AB22R3525V38A21 86BB22R3525V38A21 86CC22R3525VQ30A21 1DD204520V42A5 1CC22R4520V42A11 1AB22R4520V42A11 1AC22R4520V42A12 1CC22R4520V42A12 1CC22R4520V42A12 86DD22R4520V50A5 1CC22R4520V50A8 1CC22R4520V50A11 1AA22R4520V50A11 1CC22R4520V50A12 1AA22R4520V50A14-1AA22L4520V60A5 1CC22R4520V60A8 1AA22R4520V60A8 1CC22R4520V60A11 1AD22R4520V60A12 1AA22R4520V60A12 1CC22R4520V60A14 1CC22R4525V42A14-1AD22R4525V42A17 1AA22R4525V42A17 1CC22R4525V42A17 1DD22R4525V42A21 1AA22R4525V42A21 1BB22R4525V42A21 1CC22R4525V42A21 1BA22R4525V42A21 1BD22R4525V42A21 1DA22R4525V42A21 86AA22R4525V42A21-86DD22R4520V45A5 1BB22R4525V50A12 1DD22R4525V50A14 1AA22R4525V50A14 1DD22R4525V50A17 1AA22R4525V50A17 1CC22R4525V50A17 1DD22R4525V50A17 1DD22R4525V50A21 1AA22R4525V50A21 1CC22R4525V50A21 1DD22R4525V50A21 1BB22L4525V50A21 1AB22R4525V 50A21 1AD22R4525V50A21 1DA22R4525V50A21-1DC22R4525V50A21 86AA22R4525V50A21 86BB22R4525V60A12 1DD22R35V30A 1C22R35V30A 1D22R35V30A-1B22L35V30A-86A22R35V35A 1B22R35V35A 1C22R35V38A 1A22R35V38A 1B22R35V38A 1C22R35V38A 1D22R35V38A 1A22L35VQ35A 1C2045V42A 1A22R45V42A 1B22R45V42A 1C22R45V42A 1D22R45V42A 86A22R45V42A 86B22R45V42A 86C22R45V42A 86C22R45V42A 86D22R
