結(jie)構(gou)形式 柱(zhu)塞(sai)泵(beng)分為軸向(xiang)柱(zhu)塞(sai)泵(beng)和徑向(xiang)柱(zhu)塞(sai)泵(beng)兩種代表性的(de)結(jie)構形(xing)式；柱(zhu)塞(sai)缸由于徑向(xiang)柱(zhu)塞(sai)泵(beng)屬(shu)于一(yi)種新(xin)型的(de)技術含量比較高(gao)的(de)高(gao)效泵(beng)，隨著國產化的(de)不斷加快，徑向(xiang)柱(zhu)塞(sai)泵(beng)必然(ran)會成(cheng)為柱(zhu)塞(sai)泵(beng)應用領域(yu)的(de)重(zhong)要組成(cheng)部分。 軸(zhou)向柱(zhu)(zhu)塞泵是(shi)利用與傳動(dong)(dong)軸(zhou)平行(xing)的(de)柱(zhu)(zhu)塞在柱(zhu)(zhu)塞孔內往復(fu)運(yun)動(dong)(dong)所產生的(de)容(rong)積變化來進行(xing)工作(zuo)的(de)。由于柱(zhu)(zhu)塞和柱(zhu)(zhu)塞孔都是(shi)圓形(xing)零件，加工時可以達(da)到很高(gao)(gao)的(de)精(jing)度(du)配合，因此具有容(rong)積效率高(gao)(gao)，運(yun)轉平穩，流量均(jun)勻性好，噪聲低，工作(zuo)壓力高(gao)(gao)等優點，但對液壓油(you)的(de)污染較(jiao)(jiao)敏感，結構(gou)較(jiao)(jiao)復(fu)雜，造價較(jiao)(jiao)高(gao)(gao)。 MCY14-1B：定量柱(zhu)塞(sai)泵 SCY14-1B：手動變量柱塞泵 YCY14-1B：壓(ya)力變量(liang)柱塞泵 BCY14-1B：電(dian)液控(kong)制柱塞泵 PCY14-1B：恒壓變量(liang)柱(zhu)塞泵 柱塞泵的泵油(you)(you)機構(gou)包括兩(liang)套(tao)精(jing)密偶(ou)(ou)件(jian)：柱塞+柱塞套(tao)構(gou)成柱塞偶(ou)(ou)件(jian)、出油(you)(you)閥和出油(you)(you)閥座構(gou)成出油(you)(you)閥偶(ou)(ou)件(jian) 柱(zhu)塞和(he)柱(zhu)塞套是一對(dui)精(jing)密偶件，經配對(dui)研磨(mo)后不能互換，要求有高的精(jing)度(du)(du)和(he)光(guang)潔(jie)度(du)(du)和(he)好的耐磨(mo)性(xing)，其徑向間(jian)隙為(wei)0.002～0.003mm ; 柱(zhu)(zhu)塞頭部圓柱(zhu)(zhu)面上切有斜槽(cao)，并通過徑(jing)向孔、軸(zhou)向孔與頂部相(xiang)通，其目的是(shi)改(gai)變(bian)循環供油量；柱(zhu)(zhu)塞套(tao)上制有進、回油孔，均與泵(beng)(beng)上體內低壓油腔(qiang)相(xiang)通，柱(zhu)(zhu)塞套(tao)裝(zhuang)入泵(beng)(beng)上體后，應用定(ding)位螺釘定(ding)位。 柱(zhu)塞頭部斜槽(cao)的位置不同(tong)，改變供油量(liang)的方(fang)法也不同(tong)。 出油閥和出油閥座也是一對精密偶件，配對研(yan)磨后不能互(hu)換，其(qi)配合(he)間隙為0.01mm 。 出油閥是一個單(dan)向閥，在彈(dan)簧壓(ya)力作用(yong)下，閥上(shang)部圓錐面與(yu)閥座嚴密(mi)配合，其作用(yong)是在停供(gong)時，將(jiang)高壓(ya)油管與(yu)柱塞上(shang)端空腔隔(ge)絕，防止高壓(ya)油管內的(de)油倒流入噴油泵內。 出油閥的下部(bu)呈十字(zi)斷面(mian)(mian)，既(ji)能導(dao)向(xiang)，又能通過柴油。出油閥的錐面(mian)(mian)下有一個小的圓柱面(mian)(mian)，稱為減壓(ya)環帶(dai)，其作用是(shi)在供油終了時，使(shi)高(gao)壓(ya)油管(guan)內的油壓(ya)迅速下降，避免噴(pen)孔處產生滴油現(xian)象。當環帶(dai)落入閥座內時則(ze)使(shi)上方容積很快增(zeng)大，壓(ya)力迅速減小，停(ting)噴(pen)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 |
