ATOS葉(xie)(xie)片(pian)泵(beng)是(shi)(shi)活塞(sai)(sai)或柱(zhu)(zhu)塞(sai)(sai)的(de)(de)往復運(yun)動方向與(yu)缸體中(zhong)心軸平行的(de)(de)葉(xie)(xie)片(pian)泵(beng)。軸向葉(xie)(xie)片(pian)泵(beng)是(shi)(shi)利用與(yu)傳動軸平行的(de)(de)柱(zhu)(zhu)塞(sai)(sai)在柱(zhu)(zhu)塞(sai)(sai)孔內往復運(yun)動所產(chan)生的(de)(de)容積變化來進行工作的(de)(de)。由于柱(zhu)(zhu)塞(sai)(sai)和柱(zhu)(zhu)塞(sai)(sai)孔都是(shi)(shi)圓形零(ling)件(jian)，加工時可以達到很高(gao)的(de)(de)精(jing)度配合(he)，因此容積效率高(gao)，運(yun)轉(zhuan)平穩，流量(liang)均勻性(xing)好，噪聲低，工作壓力高(gao)等優(you)點，但對液壓油的(de)(de)污染較(jiao)敏感，結構較(jiao)復雜，造(zao)價較(jiao)高(gao)。 ATOS直軸斜盤式葉片泵 直(zhi)軸斜盤式柱塞(sai)泵(beng)(beng)分(fen)為壓(ya)(ya)(ya)力供(gong)油(you)型(xing)的(de)自(zi)吸油(you)型(xing)兩種。壓(ya)(ya)(ya)力供(gong)油(you)型(xing)液(ye)壓(ya)(ya)(ya)泵(beng)(beng)大都采(cai)用(yong)有氣壓(ya)(ya)(ya)的(de)油(you)箱，也(ye)有液(ye)壓(ya)(ya)(ya)泵(beng)(beng)本身(shen)帶有補(bu)油(you)分(fen)泵(beng)(beng)向液(ye)壓(ya)(ya)(ya)泵(beng)(beng)進油(you)口提供(gong)壓(ya)(ya)(ya)力油(you)的(de)。自(zi)吸油(you)型(xing)液(ye)壓(ya)(ya)(ya)泵(beng)(beng)的(de)自(zi)吸油(you)能(neng)力很強，無(wu)需外力供(gong)油(you)。靠氣壓(ya)(ya)(ya)供(gong)油(you)的(de)液(ye)壓(ya)(ya)(ya)油(you)箱，在每次啟動(dong)機器后，必須等(deng)液(ye)壓(ya)(ya)(ya)漬箱達(da)到使(shi)用(yong)氣壓(ya)(ya)(ya)后，才能(neng)操作(zuo)機械。如液(ye)壓(ya)(ya)(ya)油(you)箱的(de)氣壓(ya)(ya)(ya)不(bu)足(zu)時就擔任機器，會對液(ye)壓(ya)(ya)(ya)泵(beng)(beng)內的(de)與滑鞭(bian)造成(cheng)拉脫現象，出(chu)會造成(cheng)泵(beng)(beng)體內回程板(ban)與壓(ya)(ya)(ya)板(ban)的(de)非(fei)正常(chang)磨損。 ATOS徑向意大利(li)葉片泵 徑(jing)向(xiang)意大利ATOS葉(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)分(fen)為(wei)配(pei)(pei)流與(yu)軸(zhou)配(pei)(pei)流兩大類。閥(fa)配(pei)(pei)流徑(jing)向(xiang)葉(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)存在故障率高、效(xiao)率低等缺點。上70、80年代發展(zhan)的(de)(de)軸(zhou)配(pei)(pei)流徑(jing)向(xiang)柱塞(sai)泵(beng)(beng)(beng)克服了閥(fa)配(pei)(pei)流徑(jing)向(xiang)葉(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)的(de)(de)不(bu)足。由于徑(jing)向(xiang)泵(beng)(beng)(beng)結(jie)構(gou)(gou)上的(de)(de)特點，陜定(ding)了軸(zhou)配(pei)(pei)流徑(jing)向(xiang)葉(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)比軸(zhou)向(xiang)葉(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)耐沖(chong)(chong)擊(ji)、壽命長、控制(zhi)(zhi)精度高。變(bian)(bian)量行(xing)程(cheng)短泵(beng)(beng)(beng)的(de)(de)變(bian)(bian)量是在變(bian)(bian)量柱塞(sai)和限(xian)位柱塞(sai)作用下，改變(bian)(bian)定(ding)子的(de)(de)偏心距實現的(de)(de)，而定(ding)于的(de)(de)zui大偏心距為(wei) 5—9mm（根據排量大小不(bu)同），變(bian)(bian)量行(xing)程(cheng)很短。且變(bian)(bian)量機構(gou)(gou)設(she)計(ji)為(wei)高壓操(cao)縱，由控制(zhi)(zhi)閥(fa)進行(xing)控制(zhi)(zhi)。故該泵(beng)(beng)(beng)的(de)(de)響應速度快。徑(jing)向(xiang)結(jie)構(gou)(gou)設(she)計(ji)克服了如軸(zhou)向(xiang)葉(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)滑靴偏磨的(de)(de)問題。使其抗(kang)沖(chong)(chong)擊(ji)能力大幅度提(ti)高。 意大利ATOS葉片泵PFEX部分型號： PFEX2-31036/31022/1DT
