ATOS葉(xie)片泵是(shi)活(huo)塞(sai)或柱(zhu)塞(sai)的(de)往(wang)復(fu)運動(dong)(dong)方向與(yu)缸體中(zhong)心軸平(ping)(ping)行的(de)葉(xie)片泵。軸向葉(xie)片泵是(shi)利用與(yu)傳動(dong)(dong)軸平(ping)(ping)行的(de)柱(zhu)塞(sai)在柱(zhu)塞(sai)孔(kong)內(nei)往(wang)復(fu)運動(dong)(dong)所(suo)產生(sheng)的(de)容積變化來進(jin)行工(gong)作的(de)。由于(yu)柱(zhu)塞(sai)和(he)柱(zhu)塞(sai)孔(kong)都是(shi)圓形零件,加工(gong)時可以達到很(hen)高的(de)精(jing)度配合(he),因此容積效(xiao)率(lv)高,運轉平(ping)(ping)穩(wen),流量均勻性好,噪聲(sheng)低,工(gong)作壓力高等(deng)優點,但對液壓油的(de)污染較(jiao)(jiao)敏(min)感,結構(gou)較(jiao)(jiao)復(fu)雜,造價(jia)較(jiao)(jiao)高。 ATOS直軸(zhou)斜盤式葉片泵 直軸(zhou)斜(xie)盤式柱(zhu)塞泵分為壓(ya)(ya)(ya)力供(gong)油(you)(you)(you)(you)型(xing)(xing)的自(zi)吸(xi)油(you)(you)(you)(you)型(xing)(xing)兩(liang)種。壓(ya)(ya)(ya)力供(gong)油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵大都采用有氣(qi)壓(ya)(ya)(ya)的油(you)(you)(you)(you)箱(xiang)(xiang),也有液(ye)(ye)(ye)壓(ya)(ya)(ya)泵本身(shen)帶有補(bu)油(you)(you)(you)(you)分泵向(xiang)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵進油(you)(you)(you)(you)口提供(gong)壓(ya)(ya)(ya)力油(you)(you)(you)(you)的。自(zi)吸(xi)油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵的自(zi)吸(xi)油(you)(you)(you)(you)能力很強,無需(xu)外力供(gong)油(you)(you)(you)(you)。靠氣(qi)壓(ya)(ya)(ya)供(gong)油(you)(you)(you)(you)的液(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)(you)(you)箱(xiang)(xiang),在每次啟動機器(qi)后(hou),必(bi)須(xu)等液(ye)(ye)(ye)壓(ya)(ya)(ya)漬箱(xiang)(xiang)達(da)到使用氣(qi)壓(ya)(ya)(ya)后(hou),才(cai)能操作機械。如液(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)(you)(you)箱(xiang)(xiang)的氣(qi)壓(ya)(ya)(ya)不足(zu)時就擔任(ren)機器(qi),會對液(ye)(ye)(ye)壓(ya)(ya)(ya)泵內的與滑鞭造成(cheng)拉脫現象,出(chu)會造成(cheng)泵體內回(hui)程(cheng)板與壓(ya)(ya)(ya)板的非正常磨損。 ATOS徑向(xiang)意大利葉片泵(beng) 徑(jing)向(xiang)意(yi)大利ATOS葉片(pian)泵(beng)(beng)分為配流(liu)與軸(zhou)(zhou)(zhou)配流(liu)兩大類。閥配流(liu)徑(jing)向(xiang)葉片(pian)泵(beng)(beng)存(cun)在(zai)故障率(lv)(lv)高(gao)、效率(lv)(lv)低等(deng)缺點(dian)。上(shang)70、80年(nian)代發展的(de)(de)(de)軸(zhou)(zhou)(zhou)配流(liu)徑(jing)向(xiang)柱(zhu)塞(sai)泵(beng)(beng)克服(fu)了(le)(le)閥配流(liu)徑(jing)向(xiang)葉片(pian)泵(beng)(beng)的(de)(de)(de)不(bu)足(zu)。由(you)于(yu)(yu)徑(jing)向(xiang)泵(beng)(beng)結構(gou)上(shang)的(de)(de)(de)特(te)點(dian),陜(shan)定(ding)(ding)了(le)(le)軸(zhou)(zhou)(zhou)配流(liu)徑(jing)向(xiang)葉片(pian)泵(beng)(beng)比軸(zhou)(zhou)(zhou)向(xiang)葉片(pian)泵(beng)(beng)耐(nai)沖擊、壽(shou)命(ming)長、控(kong)制精度高(gao)。變量(liang)(liang)行(xing)程(cheng)(cheng)短泵(beng)(beng)的(de)(de)(de)變量(liang)(liang)是(shi)在(zai)變量(liang)(liang)柱(zhu)塞(sai)和限位柱(zhu)塞(sai)作用(yong)下,改變定(ding)(ding)子(zi)的(de)(de)(de)偏心(xin)距實現的(de)(de)(de),而(er)定(ding)(ding)于(yu)(yu)的(de)(de)(de)zui大偏心(xin)距為 5—9mm(根據(ju)排量(liang)(liang)大小不(bu)同),變量(liang)(liang)行(xing)程(cheng)(cheng)很短。且變量(liang)(liang)機(ji)構(gou)設計為高(gao)壓操縱,由(you)控(kong)制閥進行(xing)控(kong)制。故該泵(beng)(beng)的(de)(de)(de)響(xiang)應速度快。徑(jing)向(xiang)結構(gou)設計克服(fu)了(le)(le)如(ru)軸(zhou)(zhou)(zhou)向(xiang)葉片(pian)泵(beng)(beng)滑靴偏磨的(de)(de)(de)問(wen)題。使其抗沖擊能(neng)力大幅度提(ti)高(gao)。 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 |
