結構形式 柱(zhu)塞泵(beng)分為(wei)軸向柱(zhu)塞泵(beng)和徑(jing)向柱(zhu)塞泵(beng)兩種代表性的結(jie)構(gou)形(xing)式；柱(zhu)塞缸由于徑(jing)向柱(zhu)塞泵(beng)屬于一種新型的技術含量比較高(gao)的高(gao)效泵(beng)，隨著國產化的不(bu)斷加快，徑(jing)向柱(zhu)塞泵(beng)必然會成為(wei)柱(zhu)塞泵(beng)應(ying)用領域(yu)的重要組成部分。 軸(zhou)(zhou)向柱(zhu)塞(sai)泵(beng)是(shi)(shi)利(li)用與(yu)傳動軸(zhou)(zhou)平(ping)行(xing)的(de)(de)柱(zhu)塞(sai)在(zai)柱(zhu)塞(sai)孔內往復運動所產(chan)生的(de)(de)容積(ji)變化來進行(xing)工(gong)作(zuo)的(de)(de)。由于(yu)柱(zhu)塞(sai)和(he)柱(zhu)塞(sai)孔都是(shi)(shi)圓形(xing)零件，加工(gong)時可(ke)以達到很(hen)高(gao)的(de)(de)精(jing)度配(pei)合，因此具有容積(ji)效(xiao)率(lv)高(gao)，運轉平(ping)穩，流量均勻性(xing)好，噪聲低，工(gong)作(zuo)壓(ya)(ya)力高(gao)等優(you)點，但對液壓(ya)(ya)油的(de)(de)污染較(jiao)敏感，結構較(jiao)復雜，造價較(jiao)高(gao)。 柱(zhu)(zhu)塞(sai)泵的泵油(you)(you)機構(gou)包括兩套精密偶(ou)件(jian)(jian)：柱(zhu)(zhu)塞(sai)+柱(zhu)(zhu)塞(sai)套構(gou)成(cheng)柱(zhu)(zhu)塞(sai)偶(ou)件(jian)(jian)、出油(you)(you)閥(fa)和出油(you)(you)閥(fa)座(zuo)構(gou)成(cheng)出油(you)(you)閥(fa)偶(ou)件(jian)(jian) 柱塞(sai)和柱塞(sai)套是一對精密偶件，經配對研磨后不能互換，要求有高的(de)精度(du)和光潔度(du)和好的(de)耐磨性，其徑(jing)向(xiang)間隙為0.002～0.003mm 柱(zhu)塞(sai)頭部(bu)圓柱(zhu)面上(shang)(shang)切有(you)斜槽，并通(tong)過徑(jing)向孔、軸向孔與頂部(bu)相通(tong)，其目的是(shi)改變(bian)循環供油(you)量；柱(zhu)塞(sai)套上(shang)(shang)制有(you)進、回油(you)孔，均與泵上(shang)(shang)體(ti)內低壓油(you)腔相通(tong)，柱(zhu)塞(sai)套裝入(ru)泵上(shang)(shang)體(ti)后(hou)，應用定(ding)(ding)位(wei)螺釘定(ding)(ding)位(wei)。 柱塞頭部斜槽的(de)位(wei)置不(bu)同(tong)，改變供油量的(de)方法也不(bu)同(tong)。 出(chu)油閥和出(chu)油閥座(zuo)也是一對(dui)精密偶件，配對(dui)研磨后不能互換，其配合間隙為0.01mm 。 出油閥(fa)(fa)(fa)是一個單向閥(fa)(fa)(fa)，在彈簧(huang)壓力(li)作(zuo)用(yong)下，閥(fa)(fa)(fa)上部(bu)圓錐面(mian)與(yu)閥(fa)(fa)(fa)座嚴密配(pei)合，其作(zuo)用(yong)是在停供時，將高壓油管與(yu)柱(zhu)塞上端空腔(qiang)隔絕，防止高壓油管內(nei)的油倒流(liu)入噴油泵內(nei)。 出油閥(fa)的(de)下部(bu)呈十字斷面，既能(neng)導向，又能(neng)通過柴(chai)油。出油閥(fa)的(de)錐面下有一個小的(de)圓柱面，稱為減(jian)壓(ya)環(huan)帶，其作(zuo)用是(shi)在供(gong)油終了時，使高壓(ya)油管內的(de)油壓(ya)迅速(su)(su)下降(jiang)，避免噴(pen)孔處(chu)產生(sheng)滴油現象。當環(huan)帶落入閥(fa)座(zuo)內時則使上(shang)方容(rong)積很(hen)快增大(da)，壓(ya)力迅速(su)(su)減(jian)小，停噴(pen)迅速(su)(su)。 德國力士樂柱塞泵型號： A10VSO18DFR1/31R-PPA12N00 A10VSO18DFR1/31R-PPB12N00 A10VSO18DFR1/32R-VPB12N00 A10VG18HD1/10L-NSC16N003E A10VSO18DFR1/31R-PPA12N00 A10V028DR/31R-PSC12N00 A10VS028DR/31R-PPA12N00 A10VSO28DR/32R-VPB121N00 A10VSO28DFR/31R-PSA12N00 A10VSO28DFR1/31R-PPA12N00 A10VSO28DFR1/32R-VPB12N00 A10VSO28DRF1/31R-PSA12N00 E-A10VSO28DFR1/31R-PPA12N00 A10VSO28DR/31R-PSC12N00 A10V028DR/31R-PSC62K01 A10V028DFR1/31R-PSC62N00 A10VSO45DFR1/31R-PPA12N00 A10VSO45DFR1/32R-VPB12N00 A10VSO45DR/31R-PPA12N00 A10VSO45DR/31R-PPA12K25 A10VSO45DFR1/31R-PPA12N00 A10VSO58DFR1/31R-PPA12N00 A10VS045DFR1/31RPPA12NOO E-A10VSO45DFR1/31R-PPA12N00 A10VS045DFR/31R-PPA12NOO-SO32 A10VS045DR/31R-PPA12N00 A10VS045DR/52R-PC12N00 A10V045DFR1/31R-PSC62K02 A10VSO45DFR1/31R-PPA12N00 A10VS045DR/31RPPB12-NDD A10VO45DFR1/31R-PSC62K02 A10VSO71DFR1/32R-VPB22U99 A10VSO71DFR1/31R-PPA12N00 A10VSO71DFR1/32R-VPB12N00 A10VSO71DFR1/31R-PPA12KB5 A10VSO71DFR/31R-PSC62K07 A10VO71DFRI/34 PSC6402-S0225 A10VSO71FR1/31R-PPA12N00 A10VSO71DFR1/31R-PPB12NOO E-A10VSO71DFR1/31R-PPA12N00 A10VO71DFR1/31RPSC62K07 A10VSO71DFR/31R-PPA12KB3 A10VS071DR/31R-PPA12N00 A10VS071DFR/31R-PPA12N00 A10VS071DFR1/31R-PPA12N00 A10VSO71DFR1/31R-PPA12N00 A10VSO71DFR1/32R-VPB22U99 EA10VSO71DR/31R-PPA12N00 A10VS0100DR/31R-PPA12N00 A10VS0100DR/32R-VPB22U99 A10VSO100DFR1/32R-VPB12N00 A10VSO100DFR1/31R-PPA12K A10VSO100DFR1/31R-PPA12KB3 EA10VSO100PFR1/31R-PPA12N00 A10VSO100DFR/31RPSB12K24 A10VSO100DR/31R-VPA12N00 A10VSO100DR/31R-PPA12N00 A10VS0100DFR1/31R-PPA12N00 A10VS0100DFR1/32R-VPB12N00 A10V0100DR/31R-PSC11N00 A10VS0100DR/31R-PTA12N00 A10VSO100DR/31R-PPA12N00 A10VSO100DFR1/32R-VPB12N00 A10VSO140DFR1/31R-PPB12N00 A10VSO140DFLR1/31R-PPB12KO1 A10VSO-140DR/31R-PPB12N00 A10VSO140DFR1S/31RPPB12N0 A10VSO140DFR1/31R-PPB12N00 A10VS0140DFLR/31R-PPB12N00 A10VSO140DR/31R-PPB12N00 A10VS0140DRS/32R-VPB12N00 E-A10VSO140D/31R-PPB12N00 A10VSO140DFR1/31R-PPB12N00 A10VS0140DR/32R-VPB12N00 AE-A10VSO140D/31R-PPB12N00 A10VSO140DR/31R-PPB12N00 A10VSO140DRS/32R-VPB12N00 A10VSO140DFR1/31R-PPB12N00 A10VSO140DFR1/32R-VPB12N00 A10VSO140DRS/32R-VPB12N00 |
