	德國(guó)REXROTH柱塞泵A10VSO28DR/32R-VPB121N00的詳細(xì)資料：

結(jié)構(gòu)形式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；柱塞缸由于徑向柱塞泵屬于一種新型的技術(shù)含量比較高的高效泵，隨著國(guó)產(chǎn)化的不斷加快，徑向柱塞泵必然會(huì)成為柱塞泵應(yīng)用領(lǐng)域的重要組成部分。軸向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(lái)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。 MCY14-1B：定量柱塞泵 SCY14-1B：手動(dòng)變量柱塞泵 YCY14-1B：壓力變量柱塞泵 BCY14-1B：電液控制柱塞泵 PCY14-1B：恒壓變量柱塞泵柱塞泵的泵油機(jī)構(gòu)包括兩套精密偶件：柱塞+柱塞套構(gòu)成柱塞偶件、出油閥和出油閥座構(gòu)成出油閥偶件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 柱塞頭部圓柱面上切有斜槽，并通過(guò)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。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(duì)精密偶件，配對(duì)研磨后不能互換，其配合間隙為0.01mm 。出油閥是一個(gè)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(shí)，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(guò)柴油。出油閥的錐面下有一個(gè)小的圓柱面，稱為減壓環(huán)帶，其作用是在供油終了時(shí)，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(shí)則使上方容積很快增大，壓力迅速減小，停噴迅速。德國(guó)力士樂(lè)柱塞泵型號(hào)：A10VSO18DFR1/31R-PPA12N00A10VSO18DFR1/31R-PPB12N00A10VSO18DFR1/32R-VPB12N00A10VG18HD1/10L-NSC16N003EA10VSO18DFR1/31R-PPA12N00A10V028DR/31R-PSC12N00A10VS028DR/31R-PPA12N00A10VSO28DR/32R-VPB121N00A10VSO28DFR/31R-PSA12N00A10VSO28DFR1/31R-PPA12N00A10VSO28DFR1/32R-VPB12N00A10VSO28DRF1/31R-PSA12N00E-A10VSO28DFR1/31R-PPA12N00A10VSO28DR/31R-PSC12N00A10V028DR/31R-PSC62K01A10V028DFR1/31R-PSC62N00A10VSO45DFR1/31R-PPA12N00A10VSO45DFR1/32R-VPB12N00A10VSO45DR/31R-PPA12N00A10VSO45DR/31R-PPA12K25A10VSO45DFR1/31R-PPA12N00A10VSO58DFR1/31R-PPA12N00A10VS045DFR1/31RPPA12NOOE-A10VSO45DFR1/31R-PPA12N00A10VS045DFR/31R-PPA12NOO-SO32A10VS045DR/31R-PPA12N00A10VS045DR/52R-PC12N00A10V045DFR1/31R-PSC62K02A10VSO45DFR1/31R-PPA12N00A10VS045DR/31RPPB12-NDDA10VO45DFR1/31R-PSC62K02A10VSO71DFR1/32R-VPB22U99A10VSO71DFR1/31R-PPA12N00A10VSO71DFR1/32R-VPB12N00A10VSO71DFR1/31R-PPA12KB5A10VSO71DFR/31R-PSC62K07A10VO71DFRI/34 PSC6402-S0225A10VSO71FR1/31R-PPA12N00A10VSO71DFR1/31R-PPB12NOOE-A10VSO71DFR1/31R-PPA12N00A10VO71DFR1/31RPSC62K07A10VSO71DFR/31R-PPA12KB3A10VS071DR/31R-PPA12N00A10VS071DFR/31R-PPA12N00A10VS071DFR1/31R-PPA12N00A10VSO71DFR1/31R-PPA12N00A10VSO71DFR1/32R-VPB22U99EA10VSO71DR/31R-PPA12N00A10VS0100DR/31R-PPA12N00A10VS0100DR/32R-VPB22U99A10VSO100DFR1/32R-VPB12N00A10VSO100DFR1/31R-PPA12KA10VSO100DFR1/31R-PPA12KB3EA10VSO100PFR1/31R-PPA12N00A10VSO100DFR/31RPSB12K24A10VSO100DR/31R-VPA12N00A10VSO100DR/31R-PPA12N00A10VS0100DFR1/31R-PPA12N00A10VS0100DFR1/32R-VPB12N00A10V0100DR/31R-PSC11N00A10VS0100DR/31R-PTA12N00A10VSO100DR/31R-PPA12N00A10VSO100DFR1/32R-VPB12N00A10VSO140DFR1/31R-PPB12N00A10VSO140DFLR1/31R-PPB12KO1A10VSO-140DR/31R-PPB12N00A10VSO140DFR1S/31RPPB12N0A10VSO140DFR1/31R-PPB12N00A10VS0140DFLR/31R-PPB12N00A10VSO140DR/31R-PPB12N00A10VS0140DRS/32R-VPB12N00E-A10VSO140D/31R-PPB12N00A10VSO140DFR1/31R-PPB12N00A10VS0140DR/32R-VPB12N00AE-A10VSO140D/31R-PPB12N00A10VSO140DR/31R-PPB12N00A10VSO140DRS/32R-VPB12N00A10VSO140DFR1/31R-PPB12N00A10VSO140DFR1/32R-VPB12N00A10VSO140DRS/32R-VPB12N00
