ATOS葉(xie)片泵(beng)是(shi)活(huo)塞或柱(zhu)(zhu)塞的(de)往復運動(dong)方(fang)向(xiang)與(yu)缸體(ti)中心軸平行(xing)的(de)葉(xie)片泵(beng)。軸向(xiang)葉(xie)片泵(beng)是(shi)利用與(yu)傳(chuan)動(dong)軸平行(xing)的(de)柱(zhu)(zhu)塞在柱(zhu)(zhu)塞孔內往復運動(dong)所產(chan)生的(de)容積(ji)變化來(lai)進(jin)行(xing)工作(zuo)的(de)。由于柱(zhu)(zhu)塞和柱(zhu)(zhu)塞孔都是(shi)圓形零件,加工時可以(yi)達(da)到很高的(de)精度配合,因(yin)此容積(ji)效率高,運轉平穩,流量均勻性好,噪聲低(di),工作(zuo)壓力高等優(you)點(dian),但對液(ye)壓油的(de)污染較(jiao)敏感,結構較(jiao)復雜,造價(jia)較(jiao)高。 ATOS直軸斜盤式葉片泵(beng) 直(zhi)軸斜盤式柱塞泵(beng)分為壓(ya)(ya)(ya)(ya)(ya)力供(gong)(gong)油(you)(you)(you)型(xing)的(de)(de)(de)自吸(xi)油(you)(you)(you)型(xing)兩種。壓(ya)(ya)(ya)(ya)(ya)力供(gong)(gong)油(you)(you)(you)型(xing)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)大都采(cai)用有氣(qi)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)油(you)(you)(you)箱(xiang)(xiang),也有液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)本身帶有補油(you)(you)(you)分泵(beng)向液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)進油(you)(you)(you)口(kou)提供(gong)(gong)壓(ya)(ya)(ya)(ya)(ya)力油(you)(you)(you)的(de)(de)(de)。自吸(xi)油(you)(you)(you)型(xing)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)的(de)(de)(de)自吸(xi)油(you)(you)(you)能力很強,無需(xu)外(wai)力供(gong)(gong)油(you)(you)(you)。靠氣(qi)壓(ya)(ya)(ya)(ya)(ya)供(gong)(gong)油(you)(you)(you)的(de)(de)(de)液(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang),在每次(ci)啟動機(ji)器后,必須等液(ye)壓(ya)(ya)(ya)(ya)(ya)漬箱(xiang)(xiang)達到使用氣(qi)壓(ya)(ya)(ya)(ya)(ya)后,才能操(cao)作機(ji)械。如(ru)液(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang)的(de)(de)(de)氣(qi)壓(ya)(ya)(ya)(ya)(ya)不足時就擔(dan)任機(ji)器,會對液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)內(nei)的(de)(de)(de)與滑鞭造(zao)成拉脫(tuo)現象,出會造(zao)成泵(beng)體內(nei)回(hui)程板與壓(ya)(ya)(ya)(ya)(ya)板的(de)(de)(de)非正常(chang)磨損。 ATOS徑向意大利葉片泵 徑(jing)(jing)向(xiang)(xiang)意大利ATOS葉(xie)(xie)片泵(beng)分為(wei)(wei)配(pei)流與軸配(pei)流兩(liang)大類(lei)。閥(fa)配(pei)流徑(jing)(jing)向(xiang)(xiang)葉(xie)(xie)片泵(beng)存(cun)在故障率高、效率低等缺點。上(shang)70、80年代發展的(de)(de)(de)軸配(pei)流徑(jing)(jing)向(xiang)(xiang)柱塞(sai)泵(beng)克(ke)服了閥(fa)配(pei)流徑(jing)(jing)向(xiang)(xiang)葉(xie)(xie)片泵(beng)的(de)(de)(de)不足。由(you)于徑(jing)(jing)向(xiang)(xiang)泵(beng)結構上(shang)的(de)(de)(de)特點,陜定了軸配(pei)流徑(jing)(jing)向(xiang)(xiang)葉(xie)(xie)片泵(beng)比軸向(xiang)(xiang)葉(xie)(xie)片泵(beng)耐沖(chong)擊、壽(shou)命(ming)長、控(kong)制精度(du)高。變(bian)量(liang)行(xing)(xing)程短泵(beng)的(de)(de)(de)變(bian)量(liang)是在變(bian)量(liang)柱塞(sai)和(he)限位柱塞(sai)作(zuo)用(yong)下,改(gai)變(bian)定子的(de)(de)(de)偏心距(ju)實現的(de)(de)(de),而定于的(de)(de)(de)zui大偏心距(ju)為(wei)(wei) 5—9mm(根據排量(liang)大小不同),變(bian)量(liang)行(xing)(xing)程很短。且變(bian)量(liang)機構設計為(wei)(wei)高壓操縱(zong),由(you)控(kong)制閥(fa)進行(xing)(xing)控(kong)制。故該泵(beng)的(de)(de)(de)響(xiang)應速度(du)快。徑(jing)(jing)向(xiang)(xiang)結構設計克(ke)服了如軸向(xiang)(xiang)葉(xie)(xie)片泵(beng)滑靴(xue)偏磨(mo)的(de)(de)(de)問題。使其抗沖(chong)擊能力(li)大幅度(du)提高。 意大利ATOS葉片泵PFEX部分型號: PFEX2-31036/31022/1DT PFEX2-42045/31022/3DT 21 PFEX2-51150/51129/3DV 23 PFEX2-51150/51150/3DV 23 PFEX2-51150/51150/3DW 23 PFEXC-51150/3DV PFEXD-42085/43056/016/3DTA |
