結構形(xing)式 柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)分為(wei)軸向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)和徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)兩種代表性的(de)結構形式；柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)缸由于徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)屬(shu)于一種新型的(de)技術含量比較高(gao)的(de)高(gao)效泵(beng)(beng)(beng)，隨著國(guo)產化(hua)的(de)不(bu)斷(duan)加快，徑向(xiang)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)必然會(hui)成為(wei)柱(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)(beng)應用(yong)領域的(de)重要組成部分。 軸向柱(zhu)(zhu)塞(sai)(sai)泵是(shi)利用與傳動軸平行(xing)的柱(zhu)(zhu)塞(sai)(sai)在柱(zhu)(zhu)塞(sai)(sai)孔內往復(fu)運動所產生的容積變化來(lai)進行(xing)工作的。由于柱(zhu)(zhu)塞(sai)(sai)和柱(zhu)(zhu)塞(sai)(sai)孔都是(shi)圓形零件，加工時(shi)可以達(da)到很高的精度配合，因此具有容積效率高，運轉平穩，流(liu)量均勻性好，噪(zao)聲低，工作壓力高等優點，但對液壓油的污染(ran)較(jiao)敏感(gan)，結構較(jiao)復(fu)雜，造價(jia)較(jiao)高。 柱(zhu)(zhu)塞泵的(de)泵油(you)(you)(you)機構包括(kuo)兩套(tao)精(jing)密偶件(jian)(jian)：柱(zhu)(zhu)塞+柱(zhu)(zhu)塞套(tao)構成柱(zhu)(zhu)塞偶件(jian)(jian)、出(chu)油(you)(you)(you)閥(fa)和出(chu)油(you)(you)(you)閥(fa)座構成出(chu)油(you)(you)(you)閥(fa)偶件(jian)(jian) 柱塞和柱塞套是(shi)一對(dui)精密偶件，經(jing)配對(dui)研磨后不能(neng)互(hu)換，要(yao)求(qiu)有高(gao)的(de)精度(du)和光潔度(du)和好的(de)耐磨性，其(qi)徑向間隙(xi)為0.002～0.003mm ; 柱(zhu)塞(sai)頭部圓柱(zhu)面上切有(you)(you)斜(xie)槽，并通(tong)(tong)過(guo)徑向(xiang)孔、軸向(xiang)孔與頂(ding)部相(xiang)通(tong)(tong)，其(qi)目(mu)的是(shi)改變循環(huan)供油量(liang)；柱(zhu)塞(sai)套上制有(you)(you)進、回油孔，均與泵(beng)上體內低(di)壓油腔(qiang)相(xiang)通(tong)(tong)，柱(zhu)塞(sai)套裝入泵(beng)上體后(hou)，應用定(ding)位螺釘定(ding)位。 柱塞頭部斜槽(cao)的位置不(bu)同，改變(bian)供油量的方法也不(bu)同。 出油(you)閥(fa)和出油(you)閥(fa)座(zuo)也(ye)是一對(dui)精(jing)密偶件(jian)，配對(dui)研磨后(hou)不能互換，其配合(he)間隙為(wei)0.01mm 。 出油閥是一個單向閥，在彈簧(huang)壓力作(zuo)用下，閥上(shang)部(bu)圓錐面與閥座(zuo)嚴密配合(he)，其作(zuo)用是在停供時，將(jiang)高壓油管與柱塞上(shang)端空腔隔絕，防(fang)止高壓油管內的油倒流入噴油泵內。 出油(you)(you)閥(fa)的(de)(de)下(xia)部呈十字斷面，既能導向，又能通(tong)過柴油(you)(you)。出油(you)(you)閥(fa)的(de)(de)錐面下(xia)有一個(ge)小的(de)(de)圓柱面，稱為減(jian)壓(ya)環帶，其作(zuo)用是在供(gong)油(you)(you)終了時，使(shi)高壓(ya)油(you)(you)管內的(de)(de)油(you)(you)壓(ya)迅(xun)速下(xia)降(jiang)，避免噴(pen)(pen)孔(kong)處產生滴油(you)(you)現象。當環帶落入(ru)閥(fa)座內時則(ze)使(shi)上方容積(ji)很快增大，壓(ya)力(li)迅(xun)速減(jian)小，停噴(pen)(pen)迅(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 |
