ATOS葉(xie)片(pian)泵(beng)(beng)是(shi)活塞(sai)或柱(zhu)(zhu)塞(sai)的(de)(de)往(wang)復(fu)運動(dong)方(fang)向與(yu)缸體中心軸(zhou)平行的(de)(de)葉(xie)片(pian)泵(beng)(beng)。軸(zhou)向葉(xie)片(pian)泵(beng)(beng)是(shi)利用與(yu)傳動(dong)軸(zhou)平行的(de)(de)柱(zhu)(zhu)塞(sai)在(zai)柱(zhu)(zhu)塞(sai)孔內往(wang)復(fu)運動(dong)所產生的(de)(de)容(rong)積(ji)變化來進行工(gong)作的(de)(de)。由于柱(zhu)(zhu)塞(sai)和柱(zhu)(zhu)塞(sai)孔都(dou)是(shi)圓(yuan)形零(ling)件，加工(gong)時(shi)可以達(da)到很高的(de)(de)精度配(pei)合，因此(ci)容(rong)積(ji)效率高，運轉平穩，流量均勻性好，噪聲低，工(gong)作壓力高等優(you)點，但對(dui)液(ye)壓油的(de)(de)污染較敏感，結構較復(fu)雜，造價(jia)較高。 ATOS直軸(zhou)斜盤式葉片泵 直軸斜盤式(shi)柱塞泵分為壓(ya)(ya)(ya)力供(gong)(gong)油(you)(you)型(xing)的自吸油(you)(you)型(xing)兩種。壓(ya)(ya)(ya)力供(gong)(gong)油(you)(you)型(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵大都采用有(you)氣(qi)壓(ya)(ya)(ya)的油(you)(you)箱(xiang)，也(ye)有(you)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵本身(shen)帶有(you)補油(you)(you)分泵向液(ye)(ye)(ye)壓(ya)(ya)(ya)泵進油(you)(you)口提供(gong)(gong)壓(ya)(ya)(ya)力油(you)(you)的。自吸油(you)(you)型(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵的自吸油(you)(you)能力很強，無(wu)需(xu)外力供(gong)(gong)油(you)(you)。靠氣(qi)壓(ya)(ya)(ya)供(gong)(gong)油(you)(you)的液(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)箱(xiang)，在每(mei)次啟動(dong)機(ji)(ji)器(qi)后，必須等液(ye)(ye)(ye)壓(ya)(ya)(ya)漬箱(xiang)達到使用氣(qi)壓(ya)(ya)(ya)后，才能操作機(ji)(ji)械。如液(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)箱(xiang)的氣(qi)壓(ya)(ya)(ya)不(bu)足時就擔任機(ji)(ji)器(qi)，會對液(ye)(ye)(ye)壓(ya)(ya)(ya)泵內(nei)的與滑(hua)鞭造(zao)成拉脫(tuo)現象，出會造(zao)成泵體(ti)內(nei)回(hui)程(cheng)板與壓(ya)(ya)(ya)板的非(fei)正常(chang)磨損(sun)。 ATOS徑向意(yi)大(da)利(li)葉(xie)片泵(beng) 徑(jing)(jing)(jing)向(xiang)(xiang)意大利ATOS葉(xie)片(pian)(pian)(pian)泵(beng)分為配流與軸(zhou)配流兩大類。閥配流徑(jing)(jing)(jing)向(xiang)(xiang)葉(xie)片(pian)(pian)(pian)泵(beng)存在故(gu)障率高(gao)、效(xiao)率低等缺(que)點。上70、80年代發展的(de)軸(zhou)配流徑(jing)(jing)(jing)向(xiang)(xiang)柱(zhu)塞(sai)泵(beng)克(ke)服了(le)閥配流徑(jing)(jing)(jing)向(xiang)(xiang)葉(xie)片(pian)(pian)(pian)泵(beng)的(de)不(bu)(bu)足。由于(yu)(yu)徑(jing)(jing)(jing)向(xiang)(xiang)泵(beng)結(jie)構上的(de)特點，陜(shan)定了(le)軸(zhou)配流徑(jing)(jing)(jing)向(xiang)(xiang)葉(xie)片(pian)(pian)(pian)泵(beng)比軸(zhou)向(xiang)(xiang)葉(xie)片(pian)(pian)(pian)泵(beng)耐(nai)沖(chong)(chong)擊、壽命長、控(kong)制精(jing)度(du)高(gao)。變量(liang)(liang)行(xing)(xing)程短泵(beng)的(de)變量(liang)(liang)是在變量(liang)(liang)柱(zhu)塞(sai)和(he)限位柱(zhu)塞(sai)作用下(xia)，改(gai)變定子的(de)偏心(xin)距實現的(de)，而定于(yu)(yu)的(de)zui大偏心(xin)距為 5—9mm（根據(ju)排量(liang)(liang)大小不(bu)(bu)同），變量(liang)(liang)行(xing)(xing)程很(hen)短。且變量(liang)(liang)機構設(she)計(ji)為高(gao)壓(ya)操(cao)縱，由控(kong)制閥進行(xing)(xing)控(kong)制。故(gu)該泵(beng)的(de)響應速度(du)快。徑(jing)(jing)(jing)向(xiang)(xiang)結(jie)構設(she)計(ji)克(ke)服了(le)如(ru)軸(zhou)向(xiang)(xiang)葉(xie)片(pian)(pian)(pian)泵(beng)滑靴偏磨的(de)問題。使其抗(kang)沖(chong)(chong)擊能力(li)大幅(fu)度(du)提高(gao)。 意大利ATOS葉片泵PFEX部分型號： PFEX2-31036/31022/1DT
