ATOS葉片泵(beng)是(shi)活(huo)塞或柱塞的往復運(yun)動(dong)方向與缸體中心(xin)軸(zhou)平(ping)(ping)行(xing)(xing)的葉片泵(beng)。軸(zhou)向葉片泵(beng)是(shi)利用與傳動(dong)軸(zhou)平(ping)(ping)行(xing)(xing)的柱塞在柱塞孔內往復運(yun)動(dong)所產生的容積(ji)變化來進(jin)行(xing)(xing)工(gong)作(zuo)的。由于柱塞和柱塞孔都是(shi)圓形零件，加工(gong)時可(ke)以達到很高(gao)(gao)(gao)的精度(du)配合，因(yin)此容積(ji)效率高(gao)(gao)(gao)，運(yun)轉平(ping)(ping)穩，流量(liang)均勻(yun)性好，噪聲(sheng)低(di)，工(gong)作(zuo)壓力(li)高(gao)(gao)(gao)等優點，但對液(ye)壓油的污(wu)染較(jiao)敏感，結(jie)構較(jiao)復雜，造(zao)價(jia)較(jiao)高(gao)(gao)(gao)。 ATOS直軸(zhou)斜盤(pan)式葉片(pian)泵 直軸斜盤式柱塞(sai)泵(beng)(beng)(beng)分(fen)為壓(ya)(ya)(ya)(ya)(ya)力(li)供(gong)(gong)油(you)(you)(you)(you)(you)型(xing)(xing)的(de)(de)自(zi)(zi)(zi)吸(xi)油(you)(you)(you)(you)(you)型(xing)(xing)兩種。壓(ya)(ya)(ya)(ya)(ya)力(li)供(gong)(gong)油(you)(you)(you)(you)(you)型(xing)(xing)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)大都(dou)采用有(you)(you)氣壓(ya)(ya)(ya)(ya)(ya)的(de)(de)油(you)(you)(you)(you)(you)箱(xiang)，也(ye)有(you)(you)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)本身帶有(you)(you)補油(you)(you)(you)(you)(you)分(fen)泵(beng)(beng)(beng)向(xiang)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)進油(you)(you)(you)(you)(you)口提供(gong)(gong)壓(ya)(ya)(ya)(ya)(ya)力(li)油(you)(you)(you)(you)(you)的(de)(de)。自(zi)(zi)(zi)吸(xi)油(you)(you)(you)(you)(you)型(xing)(xing)液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的(de)(de)自(zi)(zi)(zi)吸(xi)油(you)(you)(you)(you)(you)能(neng)力(li)很(hen)強，無需外力(li)供(gong)(gong)油(you)(you)(you)(you)(you)。靠(kao)氣壓(ya)(ya)(ya)(ya)(ya)供(gong)(gong)油(you)(you)(you)(you)(you)的(de)(de)液(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)(you)箱(xiang)，在每(mei)次啟(qi)動(dong)機(ji)器后，必須等液(ye)壓(ya)(ya)(ya)(ya)(ya)漬箱(xiang)達到使用氣壓(ya)(ya)(ya)(ya)(ya)后，才能(neng)操作(zuo)機(ji)械(xie)。如液(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)(you)箱(xiang)的(de)(de)氣壓(ya)(ya)(ya)(ya)(ya)不足時就擔任機(ji)器，會對液(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)內的(de)(de)與滑鞭造成拉(la)脫現象，出會造成泵(beng)(beng)(beng)體內回(hui)程板與壓(ya)(ya)(ya)(ya)(ya)板的(de)(de)非正(zheng)常磨損。 ATOS徑向意大利(li)葉片(pian)泵 徑(jing)(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)意大利ATOS葉(xie)(xie)(xie)片(pian)泵分為配(pei)(pei)流(liu)與軸(zhou)配(pei)(pei)流(liu)兩大類(lei)。閥配(pei)(pei)流(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)葉(xie)(xie)(xie)片(pian)泵存在故障率高、效率低(di)等缺點。上70、80年(nian)代發展的(de)軸(zhou)配(pei)(pei)流(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)柱(zhu)塞(sai)泵克服了閥配(pei)(pei)流(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)葉(xie)(xie)(xie)片(pian)泵的(de)不足(zu)。由于(yu)徑(jing)(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)泵結構(gou)(gou)上的(de)特點，陜定了軸(zhou)配(pei)(pei)流(liu)徑(jing)(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)葉(xie)(xie)(xie)片(pian)泵比軸(zhou)向(xiang)(xiang)(xiang)(xiang)(xiang)葉(xie)(xie)(xie)片(pian)泵耐(nai)沖擊、壽命長、控制精度(du)高。變(bian)量(liang)行(xing)程短泵的(de)變(bian)量(liang)是在變(bian)量(liang)柱(zhu)塞(sai)和限位(wei)柱(zhu)塞(sai)作用下，改變(bian)定子的(de)偏心距(ju)(ju)實現的(de)，而定于(yu)的(de)zui大偏心距(ju)(ju)為 5—9mm（根據(ju)排量(liang)大小(xiao)不同），變(bian)量(liang)行(xing)程很短。且變(bian)量(liang)機構(gou)(gou)設計為高壓(ya)操(cao)縱，由控制閥進行(xing)控制。故該泵的(de)響應速(su)度(du)快(kuai)。徑(jing)(jing)向(xiang)(xiang)(xiang)(xiang)(xiang)結構(gou)(gou)設計克服了如(ru)軸(zhou)向(xiang)(xiang)(xiang)(xiang)(xiang)葉(xie)(xie)(xie)片(pian)泵滑(hua)靴(xue)偏磨的(de)問題。使其抗沖擊能(neng)力大幅度(du)提高。 意大利ATOS葉片泵PFEX部分型號： PFEX2-31036/31022/1DT
