ATOS葉(xie)片(pian)(pian)泵(beng)是活塞(sai)或柱(zhu)(zhu)塞(sai)的往復(fu)運(yun)(yun)動(dong)方向(xiang)(xiang)與缸體中(zhong)心軸(zhou)平行的葉(xie)片(pian)(pian)泵(beng)。軸(zhou)向(xiang)(xiang)葉(xie)片(pian)(pian)泵(beng)是利用與傳動(dong)軸(zhou)平行的柱(zhu)(zhu)塞(sai)在柱(zhu)(zhu)塞(sai)孔(kong)內往復(fu)運(yun)(yun)動(dong)所產生(sheng)的容積變(bian)化來(lai)進行工作的。由于柱(zhu)(zhu)塞(sai)和柱(zhu)(zhu)塞(sai)孔(kong)都是圓形零件，加工時可以達到很高(gao)的精度配合，因此容積效率高(gao)，運(yun)(yun)轉平穩，流量均勻(yun)性好(hao)，噪聲低，工作壓力高(gao)等優點，但對(dui)液壓油的污染較(jiao)敏(min)感，結構較(jiao)復(fu)雜，造價較(jiao)高(gao)。 ATOS直(zhi)軸斜盤式葉片(pian)泵 直(zhi)軸(zhou)斜盤式柱(zhu)塞泵(beng)分(fen)為(wei)壓(ya)(ya)(ya)力(li)供(gong)油(you)型(xing)的(de)(de)(de)自吸油(you)型(xing)兩種。壓(ya)(ya)(ya)力(li)供(gong)油(you)型(xing)液(ye)壓(ya)(ya)(ya)泵(beng)大都采用有(you)氣壓(ya)(ya)(ya)的(de)(de)(de)油(you)箱(xiang)，也有(you)液(ye)壓(ya)(ya)(ya)泵(beng)本身帶有(you)補油(you)分(fen)泵(beng)向液(ye)壓(ya)(ya)(ya)泵(beng)進(jin)油(you)口提供(gong)壓(ya)(ya)(ya)力(li)油(you)的(de)(de)(de)。自吸油(you)型(xing)液(ye)壓(ya)(ya)(ya)泵(beng)的(de)(de)(de)自吸油(you)能力(li)很強，無需外力(li)供(gong)油(you)。靠氣壓(ya)(ya)(ya)供(gong)油(you)的(de)(de)(de)液(ye)壓(ya)(ya)(ya)油(you)箱(xiang)，在(zai)每(mei)次啟動機(ji)器(qi)后(hou)，必須(xu)等(deng)液(ye)壓(ya)(ya)(ya)漬箱(xiang)達到使用氣壓(ya)(ya)(ya)后(hou)，才(cai)能操(cao)作機(ji)械。如液(ye)壓(ya)(ya)(ya)油(you)箱(xiang)的(de)(de)(de)氣壓(ya)(ya)(ya)不(bu)足時就擔(dan)任機(ji)器(qi)，會對液(ye)壓(ya)(ya)(ya)泵(beng)內(nei)的(de)(de)(de)與(yu)滑鞭造(zao)成拉脫現(xian)象，出(chu)會造(zao)成泵(beng)體內(nei)回程(cheng)板(ban)(ban)與(yu)壓(ya)(ya)(ya)板(ban)(ban)的(de)(de)(de)非(fei)正(zheng)常磨損。 ATOS徑向(xiang)意大利葉片泵(beng) 徑(jing)(jing)(jing)(jing)向(xiang)(xiang)意大利ATOS葉片(pian)泵(beng)(beng)分(fen)為(wei)配流(liu)與(yu)軸配流(liu)兩大類。閥(fa)配流(liu)徑(jing)(jing)(jing)(jing)向(xiang)(xiang)葉片(pian)泵(beng)(beng)存在(zai)故障率高(gao)(gao)(gao)、效(xiao)率低等缺點。上70、80年代發展的軸配流(liu)徑(jing)(jing)(jing)(jing)向(xiang)(xiang)柱(zhu)(zhu)塞泵(beng)(beng)克(ke)服了(le)閥(fa)配流(liu)徑(jing)(jing)(jing)(jing)向(xiang)(xiang)葉片(pian)泵(beng)(beng)的不(bu)足。由于(yu)徑(jing)(jing)(jing)(jing)向(xiang)(xiang)泵(beng)(beng)結(jie)構上的特(te)點，陜定(ding)了(le)軸配流(liu)徑(jing)(jing)(jing)(jing)向(xiang)(xiang)葉片(pian)泵(beng)(beng)比軸向(xiang)(xiang)葉片(pian)泵(beng)(beng)耐沖擊(ji)、壽(shou)命長、控(kong)(kong)制(zhi)精度(du)高(gao)(gao)(gao)。變量(liang)行(xing)程短(duan)泵(beng)(beng)的變量(liang)是在(zai)變量(liang)柱(zhu)(zhu)塞和(he)限(xian)位柱(zhu)(zhu)塞作用下，改變定(ding)子的偏(pian)心(xin)距(ju)(ju)實現的，而(er)定(ding)于(yu)的zui大偏(pian)心(xin)距(ju)(ju)為(wei) 5—9mm（根(gen)據排量(liang)大小不(bu)同），變量(liang)行(xing)程很短(duan)。且變量(liang)機構設(she)計為(wei)高(gao)(gao)(gao)壓操縱，由控(kong)(kong)制(zhi)閥(fa)進(jin)行(xing)控(kong)(kong)制(zhi)。故該泵(beng)(beng)的響應速度(du)快。徑(jing)(jing)(jing)(jing)向(xiang)(xiang)結(jie)構設(she)計克(ke)服了(le)如軸向(xiang)(xiang)葉片(pian)泵(beng)(beng)滑靴偏(pian)磨的問題。使其抗沖擊(ji)能(neng)力大幅度(du)提(ti)高(gao)(gao)(gao)。 意大利ATOS葉片泵PFEX部分型號： PFEX2-31036/31022/1DT
