ATOS葉片(pian)泵(beng)是(shi)活塞(sai)或柱(zhu)塞(sai)的(de)往復運(yun)(yun)動(dong)方向(xiang)與缸體中心軸平(ping)行的(de)葉片(pian)泵(beng)。軸向(xiang)葉片(pian)泵(beng)是(shi)利用與傳動(dong)軸平(ping)行的(de)柱(zhu)塞(sai)在柱(zhu)塞(sai)孔(kong)內往復運(yun)(yun)動(dong)所產生的(de)容積(ji)變化來進行工(gong)作的(de)。由于柱(zhu)塞(sai)和柱(zhu)塞(sai)孔(kong)都是(shi)圓(yuan)形零(ling)件(jian)，加工(gong)時可以(yi)達到很高的(de)精(jing)度配合，因(yin)此容積(ji)效率高，運(yun)(yun)轉平(ping)穩，流量均勻性好，噪聲(sheng)低，工(gong)作壓(ya)力高等優點，但對液壓(ya)油的(de)污染較敏感，結構較復雜，造價較高。 ATOS直軸(zhou)斜盤(pan)式葉片泵 直軸(zhou)斜盤式(shi)柱塞泵分(fen)為壓(ya)(ya)(ya)(ya)(ya)力(li)供(gong)油(you)(you)(you)(you)型(xing)(xing)的(de)自吸油(you)(you)(you)(you)型(xing)(xing)兩(liang)種。壓(ya)(ya)(ya)(ya)(ya)力(li)供(gong)油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵大都采用(yong)有氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)的(de)油(you)(you)(you)(you)箱，也有液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵本(ben)身帶(dai)有補油(you)(you)(you)(you)分(fen)泵向液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵進(jin)油(you)(you)(you)(you)口提供(gong)壓(ya)(ya)(ya)(ya)(ya)力(li)油(you)(you)(you)(you)的(de)。自吸油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵的(de)自吸油(you)(you)(you)(you)能力(li)很強，無需(xu)外力(li)供(gong)油(you)(you)(you)(you)。靠(kao)氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)供(gong)油(you)(you)(you)(you)的(de)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)箱，在每次啟(qi)動機(ji)器后，必須等液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)漬箱達(da)到使用(yong)氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)后，才能操作機(ji)械。如(ru)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)箱的(de)氣(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)不足時(shi)就擔任機(ji)器，會對(dui)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵內(nei)的(de)與(yu)滑鞭造(zao)成拉脫(tuo)現象(xiang)，出(chu)會造(zao)成泵體內(nei)回程板與(yu)壓(ya)(ya)(ya)(ya)(ya)板的(de)非正(zheng)常磨損(sun)。 ATOS徑(jing)向意大利葉片泵 徑(jing)向(xiang)(xiang)(xiang)意(yi)大(da)(da)利ATOS葉(xie)(xie)片(pian)泵(beng)(beng)分為配(pei)流與軸配(pei)流兩大(da)(da)類。閥配(pei)流徑(jing)向(xiang)(xiang)(xiang)葉(xie)(xie)片(pian)泵(beng)(beng)存在(zai)故障率高、效率低等缺點。上70、80年代發展的軸配(pei)流徑(jing)向(xiang)(xiang)(xiang)柱(zhu)塞泵(beng)(beng)克(ke)服(fu)了閥配(pei)流徑(jing)向(xiang)(xiang)(xiang)葉(xie)(xie)片(pian)泵(beng)(beng)的不(bu)足。由于徑(jing)向(xiang)(xiang)(xiang)泵(beng)(beng)結(jie)構上的特點，陜定了軸配(pei)流徑(jing)向(xiang)(xiang)(xiang)葉(xie)(xie)片(pian)泵(beng)(beng)比軸向(xiang)(xiang)(xiang)葉(xie)(xie)片(pian)泵(beng)(beng)耐(nai)沖擊、壽命長、控(kong)制精(jing)度(du)高。變(bian)量(liang)(liang)行(xing)程短(duan)泵(beng)(beng)的變(bian)量(liang)(liang)是在(zai)變(bian)量(liang)(liang)柱(zhu)塞和限位柱(zhu)塞作(zuo)用下，改變(bian)定子的偏(pian)心距實現的，而定于的zui大(da)(da)偏(pian)心距為 5—9mm（根據排量(liang)(liang)大(da)(da)小(xiao)不(bu)同(tong)），變(bian)量(liang)(liang)行(xing)程很短(duan)。且變(bian)量(liang)(liang)機構設計為高壓操縱(zong)，由控(kong)制閥進行(xing)控(kong)制。故該泵(beng)(beng)的響應速度(du)快。徑(jing)向(xiang)(xiang)(xiang)結(jie)構設計克(ke)服(fu)了如(ru)軸向(xiang)(xiang)(xiang)葉(xie)(xie)片(pian)泵(beng)(beng)滑靴(xue)偏(pian)磨(mo)的問題。使(shi)其抗沖擊能力大(da)(da)幅(fu)度(du)提高。 意大利ATOS葉片泵PFEX部分型號： PFEX2-31036/31022/1DT
