結構形式 柱塞泵(beng)(beng)(beng)分為(wei)軸(zhou)向柱塞泵(beng)(beng)(beng)和徑(jing)向柱塞泵(beng)(beng)(beng)兩種(zhong)代(dai)表性的(de)結構形式；柱塞缸由于徑(jing)向柱塞泵(beng)(beng)(beng)屬于一種(zhong)新型的(de)技術(shu)含(han)量比較高(gao)的(de)高(gao)效泵(beng)(beng)(beng)，隨著國產(chan)化的(de)不斷(duan)加快，徑(jing)向柱塞泵(beng)(beng)(beng)必然會成為(wei)柱塞泵(beng)(beng)(beng)應用(yong)領(ling)域(yu)的(de)重要組成部分。 軸向柱(zhu)(zhu)(zhu)塞(sai)泵(beng)是利(li)用與傳動(dong)軸平(ping)行的(de)(de)柱(zhu)(zhu)(zhu)塞(sai)在柱(zhu)(zhu)(zhu)塞(sai)孔內(nei)往(wang)復運(yun)動(dong)所產生的(de)(de)容(rong)積(ji)(ji)變化來進行工(gong)作的(de)(de)。由(you)于柱(zhu)(zhu)(zhu)塞(sai)和柱(zhu)(zhu)(zhu)塞(sai)孔都是圓(yuan)形零件，加工(gong)時(shi)可以達到很高(gao)(gao)的(de)(de)精度(du)配(pei)合，因此具(ju)有容(rong)積(ji)(ji)效率高(gao)(gao)，運(yun)轉平(ping)穩，流量均勻性好，噪聲低(di)，工(gong)作壓力高(gao)(gao)等優點，但對液壓油的(de)(de)污染(ran)較(jiao)敏感，結構較(jiao)復雜，造價較(jiao)高(gao)(gao)。 柱(zhu)(zhu)(zhu)塞泵的泵油(you)機構包括(kuo)兩套(tao)精密偶件(jian)：柱(zhu)(zhu)(zhu)塞+柱(zhu)(zhu)(zhu)塞套(tao)構成(cheng)柱(zhu)(zhu)(zhu)塞偶件(jian)、出(chu)(chu)油(you)閥(fa)(fa)和出(chu)(chu)油(you)閥(fa)(fa)座構成(cheng)出(chu)(chu)油(you)閥(fa)(fa)偶件(jian) 柱塞和(he)柱塞套是一對(dui)精密偶(ou)件，經配對(dui)研磨(mo)后不能互換，要求有(you)高的精度和(he)光潔度和(he)好的耐磨(mo)性，其徑向間(jian)隙為0.002～0.003mm 柱塞頭部圓柱面上切有斜槽，并通過徑(jing)向孔、軸向孔與頂(ding)部相通，其(qi)目的是改(gai)變循環供(gong)油量；柱塞套上制有進、回油孔，均與泵(beng)上體(ti)內低壓油腔相通，柱塞套裝入(ru)泵(beng)上體(ti)后，應用定位螺釘定位。 ; 柱塞頭部斜槽的位(wei)置不同(tong)，改變(bian)供油量的方法也不同(tong)。 出油閥和出油閥座也是(shi)一(yi)對(dui)精密偶件，配對(dui)研(yan)磨后不(bu)能互換，其配合(he)間隙為0.01mm 。 出油閥是一個單(dan)向閥，在彈(dan)簧壓(ya)力作用下，閥上部圓錐面與(yu)閥座嚴密配合，其作用是在停供時，將高壓(ya)油管與(yu)柱塞(sai)上端空腔(qiang)隔絕(jue)，防止高壓(ya)油管內的油倒流入噴油泵(beng)內。 出(chu)油(you)閥的(de)下部呈十字(zi)斷(duan)面(mian)，既能(neng)導向，又能(neng)通過柴(chai)油(you)。出(chu)油(you)閥的(de)錐面(mian)下有一個(ge)小的(de)圓(yuan)柱面(mian)，稱為減壓環帶，其作(zuo)用是在供(gong)油(you)終了時，使高壓油(you)管(guan)內(nei)的(de)油(you)壓迅(xun)(xun)(xun)速(su)下降，避免噴(pen)孔處產生滴油(you)現象(xiang)。當環帶落入閥座內(nei)時則使上方容積很快(kuai)增(zeng)大，壓力迅(xun)(xun)(xun)速(su)減小，停(ting)噴(pen)迅(xun)(xun)(xun)速(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 |
