結構形式 柱塞泵(beng)(beng)(beng)分為(wei)軸向(xiang)柱塞泵(beng)(beng)(beng)和徑(jing)向(xiang)柱塞泵(beng)(beng)(beng)兩種代表(biao)性的(de)結構形式(shi)；柱塞缸由于徑(jing)向(xiang)柱塞泵(beng)(beng)(beng)屬于一種新型的(de)技(ji)術含量(liang)比較高(gao)的(de)高(gao)效泵(beng)(beng)(beng)，隨著國產化的(de)不斷(duan)加快，徑(jing)向(xiang)柱塞泵(beng)(beng)(beng)必然(ran)會(hui)成為(wei)柱塞泵(beng)(beng)(beng)應(ying)用(yong)領域的(de)重要(yao)組成部分。 軸向柱(zhu)(zhu)(zhu)塞(sai)泵是(shi)利(li)用(yong)與傳動(dong)軸平(ping)行的(de)(de)柱(zhu)(zhu)(zhu)塞(sai)在柱(zhu)(zhu)(zhu)塞(sai)孔內往(wang)復(fu)運動(dong)所產生的(de)(de)容(rong)積變(bian)化來進行工作的(de)(de)。由于柱(zhu)(zhu)(zhu)塞(sai)和(he)柱(zhu)(zhu)(zhu)塞(sai)孔都(dou)是(shi)圓形零(ling)件，加工時可以(yi)達(da)到很高(gao)的(de)(de)精度配合(he)，因此具有容(rong)積效率高(gao)，運轉平(ping)穩，流(liu)量均勻性好，噪(zao)聲(sheng)低，工作壓(ya)力高(gao)等優點，但對液壓(ya)油的(de)(de)污染(ran)較(jiao)敏感(gan)，結構較(jiao)復(fu)雜，造價較(jiao)高(gao)。 MCY14-1B：定量柱(zhu)塞(sai)泵 SCY14-1B：手動變量柱(zhu)塞泵 YCY14-1B：壓(ya)力變量柱(zhu)塞泵 BCY14-1B：電液(ye)控制(zhi)柱(zhu)塞(sai)泵 PCY14-1B：恒壓變量柱塞泵 柱塞(sai)泵(beng)的泵(beng)油機構(gou)包(bao)括兩套精密偶件(jian)(jian)：柱塞(sai)+柱塞(sai)套構(gou)成柱塞(sai)偶件(jian)(jian)、出(chu)(chu)油閥和出(chu)(chu)油閥座構(gou)成出(chu)(chu)油閥偶件(jian)(jian) 柱塞(sai)和柱塞(sai)套是(shi)一對(dui)精(jing)密(mi)偶件，經配(pei)對(dui)研磨(mo)后不能互換，要求(qiu)有(you)高的精(jing)度和光潔度和好(hao)的耐(nai)磨(mo)性，其徑(jing)向(xiang)間(jian)隙為0.002～0.003mm 柱(zhu)(zhu)塞(sai)頭部圓柱(zhu)(zhu)面上切有斜槽，并通過(guo)徑向(xiang)(xiang)孔(kong)(kong)、軸(zhou)向(xiang)(xiang)孔(kong)(kong)與頂部相通，其目的是(shi)改變(bian)循環供油量；柱(zhu)(zhu)塞(sai)套上制有進、回油孔(kong)(kong)，均與泵上體內低壓油腔相通，柱(zhu)(zhu)塞(sai)套裝(zhuang)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(gai)變(bian)供油(you)量(liang)的方(fang)法也(ye)不同。 出油閥和出油閥座也是一對(dui)精密(mi)偶(ou)件，配(pei)對(dui)研磨后不能互換，其(qi)配(pei)合(he)間(jian)隙(xi)為0.01mm 。 出油(you)閥是一(yi)個單向閥，在(zai)彈簧壓力作用下，閥上部(bu)圓錐(zhui)面與閥座(zuo)嚴密配合，其作用是在(zai)停供時，將高(gao)壓油(you)管(guan)與柱塞上端(duan)空腔隔絕，防止高(gao)壓油(you)管(guan)內的(de)油(you)倒(dao)流入噴(pen)油(you)泵內。 出油(you)閥的下(xia)部呈十字斷(duan)面，既能導向，又能通(tong)過柴油(you)。出油(you)閥的錐面下(xia)有一個(ge)小(xiao)的圓柱面，稱為減(jian)壓環帶(dai)，其(qi)作用是(shi)在供油(you)終了時，使高壓油(you)管內(nei)的油(you)壓迅(xun)(xun)速下(xia)降，避免(mian)噴孔處產生滴油(you)現(xian)象(xiang)。當環帶(dai)落入閥座內(nei)時則使上方容(rong)積很快增大，壓力迅(xun)(xun)速減(jian)小(xiao)，停噴迅(xun)(xun)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 |
