結構形式 柱(zhu)(zhu)(zhu)(zhu)塞泵(beng)分為軸向(xiang)柱(zhu)(zhu)(zhu)(zhu)塞泵(beng)和徑(jing)向(xiang)柱(zhu)(zhu)(zhu)(zhu)塞泵(beng)兩(liang)種(zhong)代表性(xing)的(de)結構形式；柱(zhu)(zhu)(zhu)(zhu)塞缸(gang)由于徑(jing)向(xiang)柱(zhu)(zhu)(zhu)(zhu)塞泵(beng)屬于一種(zhong)新(xin)型的(de)技術含(han)量比較高的(de)高效泵(beng)，隨著國產化的(de)不斷(duan)加快，徑(jing)向(xiang)柱(zhu)(zhu)(zhu)(zhu)塞泵(beng)必然(ran)會成為柱(zhu)(zhu)(zhu)(zhu)塞泵(beng)應用(yong)領域的(de)重要(yao)組成部分。 軸(zhou)向柱(zhu)塞(sai)泵是利用(yong)與傳動(dong)(dong)軸(zhou)平(ping)行(xing)的(de)柱(zhu)塞(sai)在柱(zhu)塞(sai)孔(kong)內(nei)往復(fu)運動(dong)(dong)所(suo)產生(sheng)的(de)容積(ji)變化來進行(xing)工(gong)(gong)作(zuo)(zuo)的(de)。由(you)于柱(zhu)塞(sai)和柱(zhu)塞(sai)孔(kong)都是圓形零件，加(jia)工(gong)(gong)時可以(yi)達到很(hen)高(gao)(gao)的(de)精度配合，因此具有容積(ji)效率高(gao)(gao)，運轉平(ping)穩(wen)，流量均勻性好，噪(zao)聲低，工(gong)(gong)作(zuo)(zuo)壓力高(gao)(gao)等(deng)優點，但對液壓油的(de)污染較(jiao)敏感，結構(gou)較(jiao)復(fu)雜(za)，造價(jia)較(jiao)高(gao)(gao)。 柱(zhu)塞(sai)泵的泵油(you)機構(gou)包(bao)括兩套(tao)精(jing)密偶件(jian)：柱(zhu)塞(sai)+柱(zhu)塞(sai)套(tao)構(gou)成(cheng)柱(zhu)塞(sai)偶件(jian)、出油(you)閥(fa)和出油(you)閥(fa)座(zuo)構(gou)成(cheng)出油(you)閥(fa)偶件(jian) 柱(zhu)(zhu)塞和柱(zhu)(zhu)塞套(tao)是一對(dui)精密偶(ou)件，經配(pei)對(dui)研磨后不能(neng)互換，要求(qiu)有(you)高(gao)的精度和光(guang)潔度和好的耐(nai)磨性，其徑向(xiang)間(jian)隙為0.002～0.003mm 柱(zhu)塞(sai)頭部(bu)圓柱(zhu)面上(shang)(shang)(shang)切(qie)有斜槽，并(bing)通過徑向孔(kong)、軸向孔(kong)與(yu)頂部(bu)相(xiang)通，其目的是(shi)改變(bian)循環供(gong)油量；柱(zhu)塞(sai)套(tao)(tao)上(shang)(shang)(shang)制有進、回油孔(kong)，均與(yu)泵上(shang)(shang)(shang)體內低壓(ya)油腔相(xiang)通，柱(zhu)塞(sai)套(tao)(tao)裝(zhuang)入泵上(shang)(shang)(shang)體后，應(ying)用(yong)定位螺(luo)釘定位。 柱塞頭(tou)部斜槽的位置不同，改變供油量的方(fang)法也不同。 出油閥和出油閥座也是(shi)一(yi)對精密偶件，配對研磨后不能互(hu)換，其配合(he)間隙(xi)為0.01mm 。 出油(you)(you)閥(fa)(fa)是一個單向(xiang)閥(fa)(fa)，在(zai)彈簧壓(ya)(ya)力(li)作用下，閥(fa)(fa)上部圓錐面與(yu)(yu)閥(fa)(fa)座嚴密配合，其作用是在(zai)停(ting)供時，將高壓(ya)(ya)油(you)(you)管與(yu)(yu)柱塞(sai)上端空(kong)腔隔絕，防止高壓(ya)(ya)油(you)(you)管內(nei)(nei)的(de)油(you)(you)倒流入噴油(you)(you)泵內(nei)(nei)。 出(chu)油(you)(you)(you)閥(fa)的(de)下(xia)部(bu)呈(cheng)十字斷面(mian)(mian)，既能(neng)導(dao)向(xiang)，又能(neng)通過柴油(you)(you)(you)。出(chu)油(you)(you)(you)閥(fa)的(de)錐面(mian)(mian)下(xia)有一個小的(de)圓柱面(mian)(mian)，稱為減(jian)壓(ya)(ya)環(huan)帶，其(qi)作用(yong)是在供油(you)(you)(you)終了(le)時，使(shi)(shi)高壓(ya)(ya)油(you)(you)(you)管內(nei)的(de)油(you)(you)(you)壓(ya)(ya)迅(xun)速(su)(su)下(xia)降，避(bi)免噴(pen)孔(kong)處產生滴油(you)(you)(you)現象。當(dang)環(huan)帶落入閥(fa)座內(nei)時則(ze)使(shi)(shi)上方容積很快增大，壓(ya)(ya)力迅(xun)速(su)(su)減(jian)小，停噴(pen)迅(xun)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 |
