ATOS葉(xie)片泵是(shi)活塞或柱塞的(de)往(wang)復(fu)運動(dong)方向與(yu)缸體中心軸平(ping)(ping)行(xing)的(de)葉(xie)片泵。軸向葉(xie)片泵是(shi)利用與(yu)傳動(dong)軸平(ping)(ping)行(xing)的(de)柱塞在柱塞孔(kong)內往(wang)復(fu)運動(dong)所(suo)產生的(de)容(rong)積(ji)變化(hua)來進行(xing)工(gong)作的(de)。由于柱塞和柱塞孔(kong)都是(shi)圓形零件,加工(gong)時(shi)可以達到很高(gao)的(de)精度配合,因(yin)此容(rong)積(ji)效率(lv)高(gao),運轉平(ping)(ping)穩,流量均勻性好,噪聲低,工(gong)作壓力高(gao)等優點(dian),但對(dui)液壓油(you)的(de)污染較敏感,結構較復(fu)雜,造價較高(gao)。 ATOS直軸斜盤(pan)式葉片泵(beng) 直軸(zhou)斜盤式柱(zhu)塞(sai)泵(beng)分為壓(ya)(ya)(ya)力供油(you)(you)(you)(you)型(xing)(xing)的(de)自(zi)吸油(you)(you)(you)(you)型(xing)(xing)兩種。壓(ya)(ya)(ya)力供油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)大都采用有氣(qi)壓(ya)(ya)(ya)的(de)油(you)(you)(you)(you)箱,也(ye)有液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)本身帶有補油(you)(you)(you)(you)分泵(beng)向液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)進油(you)(you)(you)(you)口提供壓(ya)(ya)(ya)力油(you)(you)(you)(you)的(de)。自(zi)吸油(you)(you)(you)(you)型(xing)(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)的(de)自(zi)吸油(you)(you)(you)(you)能力很強,無需外力供油(you)(you)(you)(you)。靠氣(qi)壓(ya)(ya)(ya)供油(you)(you)(you)(you)的(de)液(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)(you)(you)箱,在(zai)每次啟動機(ji)器后(hou)(hou),必須等(deng)液(ye)(ye)(ye)壓(ya)(ya)(ya)漬箱達到使用氣(qi)壓(ya)(ya)(ya)后(hou)(hou),才能操(cao)作機(ji)械。如液(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)(you)(you)箱的(de)氣(qi)壓(ya)(ya)(ya)不足(zu)時就擔任機(ji)器,會對液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)內的(de)與滑鞭造成拉脫現象,出會造成泵(beng)體內回程板與壓(ya)(ya)(ya)板的(de)非正(zheng)常磨損(sun)。 ATOS徑向意大利葉(xie)片泵 徑向(xiang)(xiang)(xiang)意大利(li)ATOS葉片(pian)(pian)泵(beng)(beng)(beng)分為(wei)配流(liu)(liu)(liu)與軸(zhou)配流(liu)(liu)(liu)兩大類。閥配流(liu)(liu)(liu)徑向(xiang)(xiang)(xiang)葉片(pian)(pian)泵(beng)(beng)(beng)存(cun)在故(gu)(gu)障率(lv)高(gao)(gao)、效率(lv)低等缺點。上70、80年代(dai)發(fa)展的(de)(de)(de)軸(zhou)配流(liu)(liu)(liu)徑向(xiang)(xiang)(xiang)柱塞(sai)(sai)泵(beng)(beng)(beng)克服了(le)閥配流(liu)(liu)(liu)徑向(xiang)(xiang)(xiang)葉片(pian)(pian)泵(beng)(beng)(beng)的(de)(de)(de)不(bu)足。由于(yu)徑向(xiang)(xiang)(xiang)泵(beng)(beng)(beng)結構(gou)上的(de)(de)(de)特(te)點,陜定(ding)了(le)軸(zhou)配流(liu)(liu)(liu)徑向(xiang)(xiang)(xiang)葉片(pian)(pian)泵(beng)(beng)(beng)比軸(zhou)向(xiang)(xiang)(xiang)葉片(pian)(pian)泵(beng)(beng)(beng)耐沖擊(ji)、壽(shou)命長、控(kong)制精度高(gao)(gao)。變(bian)量行(xing)(xing)程(cheng)短(duan)泵(beng)(beng)(beng)的(de)(de)(de)變(bian)量是在變(bian)量柱塞(sai)(sai)和限位柱塞(sai)(sai)作用下,改變(bian)定(ding)子的(de)(de)(de)偏心距(ju)實現的(de)(de)(de),而定(ding)于(yu)的(de)(de)(de)zui大偏心距(ju)為(wei) 5—9mm(根據排(pai)量大小不(bu)同(tong)),變(bian)量行(xing)(xing)程(cheng)很短(duan)。且變(bian)量機構(gou)設計(ji)為(wei)高(gao)(gao)壓操縱,由控(kong)制閥進行(xing)(xing)控(kong)制。故(gu)(gu)該泵(beng)(beng)(beng)的(de)(de)(de)響應(ying)速度快。徑向(xiang)(xiang)(xiang)結構(gou)設計(ji)克服了(le)如軸(zhou)向(xiang)(xiang)(xiang)葉片(pian)(pian)泵(beng)(beng)(beng)滑靴偏磨的(de)(de)(de)問(wen)題。使其抗沖擊(ji)能力大幅(fu)度提高(gao)(gao)。 意大利ATOS葉片泵PFEX部分型號: PFEX2-31036/31022/1DT PFEX2-42045/31022/3DT 21 PFEX2-51150/51129/3DV 23 PFEX2-51150/51150/3DV 23 PFEX2-51150/51150/3DW 23 PFEXC-51150/3DV PFEXD-42085/43056/016/3DTA |
