結構(gou)形(xing)式 柱(zhu)(zhu)塞泵分為軸(zhou)向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞泵和徑(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞泵兩(liang)種代表(biao)性(xing)的(de)(de)結構(gou)形(xing)式;柱(zhu)(zhu)塞缸由于徑(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞泵屬于一(yi)種新型的(de)(de)技術含(han)量比(bi)較高的(de)(de)高效(xiao)泵,隨著國產化的(de)(de)不斷加快(kuai),徑(jing)向(xiang)(xiang)(xiang)柱(zhu)(zhu)塞泵必然會成(cheng)為柱(zhu)(zhu)塞泵應用(yong)領域的(de)(de)重要組成(cheng)部分。 軸(zhou)向柱(zhu)塞(sai)泵是利(li)用與傳動(dong)軸(zhou)平(ping)行(xing)的柱(zhu)塞(sai)在柱(zhu)塞(sai)孔內往復運(yun)動(dong)所(suo)產生(sheng)的容積(ji)變化來進行(xing)工作的。由于柱(zhu)塞(sai)和柱(zhu)塞(sai)孔都是圓形零件,加工時可(ke)以達到很高(gao)的精度配(pei)合,因此具(ju)有容積(ji)效(xiao)率高(gao),運(yun)轉平(ping)穩,流量均勻性好,噪聲低,工作壓(ya)力高(gao)等優點,但對液(ye)壓(ya)油的污染較敏感,結(jie)構較復雜(za),造價較高(gao)。 MCY14-1B:定量柱(zhu)塞泵 SCY14-1B:手動變量柱塞泵 YCY14-1B:壓(ya)力(li)變量柱塞泵 BCY14-1B:電液控(kong)制(zhi)柱塞泵(beng) PCY14-1B:恒壓變量(liang)柱塞泵 柱(zhu)塞(sai)泵的泵油機構包括(kuo)兩套精密(mi)偶(ou)件(jian):柱(zhu)塞(sai)+柱(zhu)塞(sai)套構成柱(zhu)塞(sai)偶(ou)件(jian)、出(chu)(chu)油閥(fa)和(he)出(chu)(chu)油閥(fa)座構成出(chu)(chu)油閥(fa)偶(ou)件(jian) 柱塞和(he)(he)柱塞套(tao)是一對(dui)(dui)精密偶件(jian),經配對(dui)(dui)研磨(mo)(mo)后不能互換,要求有高的精度和(he)(he)光潔(jie)度和(he)(he)好的耐(nai)磨(mo)(mo)性(xing),其(qi)徑向間隙為0.002~0.003mm 柱塞頭部圓(yuan)柱面上切有斜槽(cao),并通(tong)過徑向孔、軸(zhou)向孔與頂部相通(tong),其目(mu)的是改變循環供油量;柱塞套上制有進、回油孔,均與泵上體(ti)內低(di)壓油腔相通(tong),柱塞套裝入(ru)泵上體(ti)后,應用定位螺(luo)釘定位。 柱塞頭部斜(xie)槽的位置不(bu)同,改(gai)變供油量的方法也不(bu)同。 出油閥(fa)和出油閥(fa)座也是一對精密偶件(jian),配對研磨后不(bu)能互換,其配合間(jian)隙為0.01mm 。 出油(you)閥是(shi)一個單向閥,在彈簧壓力作用下,閥上部(bu)圓錐面與(yu)閥座嚴(yan)密配合,其作用是(shi)在停(ting)供時,將高(gao)壓油(you)管與(yu)柱塞上端空(kong)腔隔絕,防(fang)止高(gao)壓油(you)管內的油(you)倒流(liu)入噴油(you)泵內。 出油(you)閥的(de)下部呈十字斷面(mian),既能導向,又能通過柴油(you)。出油(you)閥的(de)錐面(mian)下有一個小(xiao)的(de)圓柱(zhu)面(mian),稱為減(jian)壓(ya)環帶,其作用是在供油(you)終(zhong)了時,使高壓(ya)油(you)管內的(de)油(you)壓(ya)迅速下降,避(bi)免噴孔處產生滴(di)油(you)現象(xiang)。當環帶落入閥座(zuo)內時則使上方(fang)容積很快增(zeng)大,壓(ya)力(li)迅速減(jian)小(xiao),停噴迅速。 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 |
