意大利ATOS葉片泵PFEX2-42045/31022/3DT 21 ATOS葉片(pian)泵是活塞或柱塞的(de)(de)往復運動(dong)(dong)方向與缸體中心軸(zhou)平(ping)行的(de)(de)葉片(pian)泵。軸(zhou)向葉片(pian)泵是利(li)用(yong)與傳動(dong)(dong)軸(zhou)平(ping)行的(de)(de)柱塞在柱塞孔內往復運動(dong)(dong)所產生的(de)(de)容積變化來(lai)進行工(gong)作的(de)(de)。由于柱塞和柱塞孔都是圓形零(ling)件，加工(gong)時(shi)可以達到很高(gao)的(de)(de)精(jing)度配合，因(yin)此容積效率高(gao)，運轉平(ping)穩，流量均勻(yun)性好，噪聲低(di)，工(gong)作壓力(li)高(gao)等優點，但對液壓油的(de)(de)污染較(jiao)敏感，結構較(jiao)復雜(za)，造價較(jiao)高(gao)。 ATOS直軸斜盤式葉(xie)片泵(beng) 直(zhi)軸斜(xie)盤(pan)式柱塞泵(beng)(beng)分(fen)為壓(ya)(ya)(ya)(ya)(ya)力供(gong)油(you)型的自(zi)吸油(you)型兩(liang)種。壓(ya)(ya)(ya)(ya)(ya)力供(gong)油(you)型液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)大都(dou)采用有氣(qi)壓(ya)(ya)(ya)(ya)(ya)的油(you)箱(xiang)，也(ye)有液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)本身帶有補(bu)油(you)分(fen)泵(beng)(beng)向液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)進油(you)口提供(gong)壓(ya)(ya)(ya)(ya)(ya)力油(you)的。自(zi)吸油(you)型液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)的自(zi)吸油(you)能(neng)力很強，無需外力供(gong)油(you)。靠氣(qi)壓(ya)(ya)(ya)(ya)(ya)供(gong)油(you)的液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)箱(xiang)，在每次啟動機器后(hou)，必須等液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)漬箱(xiang)達到(dao)使用氣(qi)壓(ya)(ya)(ya)(ya)(ya)后(hou)，才(cai)能(neng)操作機械。如液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)箱(xiang)的氣(qi)壓(ya)(ya)(ya)(ya)(ya)不足時就(jiu)擔(dan)任機器，會對液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)內的與滑鞭造成(cheng)拉(la)脫(tuo)現象(xiang)，出會造成(cheng)泵(beng)(beng)體內回程(cheng)板(ban)與壓(ya)(ya)(ya)(ya)(ya)板(ban)的非正常磨(mo)損。 ATOS徑(jing)向意大(da)利葉片泵 徑(jing)向(xiang)(xiang)(xiang)(xiang)意大(da)(da)利ATOS葉(xie)片(pian)泵(beng)(beng)分為配(pei)流(liu)與(yu)軸(zhou)配(pei)流(liu)兩大(da)(da)類(lei)。閥(fa)(fa)配(pei)流(liu)徑(jing)向(xiang)(xiang)(xiang)(xiang)葉(xie)片(pian)泵(beng)(beng)存在故(gu)障(zhang)率高(gao)(gao)、效率低(di)等缺點。上70、80年代發展的(de)軸(zhou)配(pei)流(liu)徑(jing)向(xiang)(xiang)(xiang)(xiang)柱塞泵(beng)(beng)克(ke)服(fu)了閥(fa)(fa)配(pei)流(liu)徑(jing)向(xiang)(xiang)(xiang)(xiang)葉(xie)片(pian)泵(beng)(beng)的(de)不足。由于(yu)徑(jing)向(xiang)(xiang)(xiang)(xiang)泵(beng)(beng)結構(gou)上的(de)特點，陜定(ding)了軸(zhou)配(pei)流(liu)徑(jing)向(xiang)(xiang)(xiang)(xiang)葉(xie)片(pian)泵(beng)(beng)比軸(zhou)向(xiang)(xiang)(xiang)(xiang)葉(xie)片(pian)泵(beng)(beng)耐沖擊、壽命長、控(kong)制(zhi)精度高(gao)(gao)。變(bian)(bian)量(liang)(liang)行(xing)程(cheng)短(duan)泵(beng)(beng)的(de)變(bian)(bian)量(liang)(liang)是(shi)在變(bian)(bian)量(liang)(liang)柱塞和限位柱塞作用(yong)下，改變(bian)(bian)定(ding)子的(de)偏心(xin)距實現的(de)，而定(ding)于(yu)的(de)zui大(da)(da)偏心(xin)距為 5—9mm（根據排量(liang)(liang)大(da)(da)小不同），變(bian)(bian)量(liang)(liang)行(xing)程(cheng)很短(duan)。且變(bian)(bian)量(liang)(liang)機構(gou)設計(ji)為高(gao)(gao)壓(ya)操縱，由控(kong)制(zhi)閥(fa)(fa)進行(xing)控(kong)制(zhi)。故(gu)該(gai)泵(beng)(beng)的(de)響應速度快。徑(jing)向(xiang)(xiang)(xiang)(xiang)結構(gou)設計(ji)克(ke)服(fu)了如軸(zhou)向(xiang)(xiang)(xiang)(xiang)葉(xie)片(pian)泵(beng)(beng)滑靴(xue)偏磨的(de)問(wen)題。使其抗沖擊能力(li)大(da)(da)幅度提高(gao)(gao)。 意大利ATOS葉片泵PFEX2型號： PFEX2-31036/31022/1DT
