ATOS葉片泵是活塞或柱塞的往復運動方向與缸體中心軸平行的葉片泵。軸向葉片泵是利用與傳動軸平行的柱塞在柱塞孔內往復運動所產生的容積變化來進行工作的。由于柱塞和柱塞孔都是圓形零件,加工時可以達到很高的精度配合,因此容積效率高,運轉平穩,流量均勻性好,噪聲低,工作壓力高等優點,但對液壓油的污染較敏感,結構較復雜,造價較高。 ATOS直軸斜盤(pan)式(shi)葉(xie)片泵 直(zhi)軸斜盤式(shi)柱塞泵(beng)(beng)分為(wei)壓(ya)(ya)(ya)(ya)力(li)供(gong)油(you)(you)(you)型(xing)的(de)(de)自(zi)吸(xi)(xi)油(you)(you)(you)型(xing)兩(liang)種。壓(ya)(ya)(ya)(ya)力(li)供(gong)油(you)(you)(you)型(xing)液(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)大(da)都(dou)采用有氣(qi)(qi)壓(ya)(ya)(ya)(ya)的(de)(de)油(you)(you)(you)箱(xiang),也有液(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)本身(shen)帶有補(bu)油(you)(you)(you)分泵(beng)(beng)向(xiang)液(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)進油(you)(you)(you)口提供(gong)壓(ya)(ya)(ya)(ya)力(li)油(you)(you)(you)的(de)(de)。自(zi)吸(xi)(xi)油(you)(you)(you)型(xing)液(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)的(de)(de)自(zi)吸(xi)(xi)油(you)(you)(you)能力(li)很(hen)強,無(wu)需外力(li)供(gong)油(you)(you)(you)。靠氣(qi)(qi)壓(ya)(ya)(ya)(ya)供(gong)油(you)(you)(you)的(de)(de)液(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)箱(xiang),在每(mei)次啟動機器后,必須等(deng)液(ye)(ye)壓(ya)(ya)(ya)(ya)漬箱(xiang)達到(dao)使用氣(qi)(qi)壓(ya)(ya)(ya)(ya)后,才(cai)能操作機械。如液(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)箱(xiang)的(de)(de)氣(qi)(qi)壓(ya)(ya)(ya)(ya)不足(zu)時就擔(dan)任(ren)機器,會對液(ye)(ye)壓(ya)(ya)(ya)(ya)泵(beng)(beng)內的(de)(de)與滑鞭(bian)造成(cheng)拉脫現象,出會造成(cheng)泵(beng)(beng)體(ti)內回程板與壓(ya)(ya)(ya)(ya)板的(de)(de)非正常磨(mo)損。 ATOS徑(jing)向(xiang)意(yi)大利葉片(pian)泵 徑(jing)(jing)向(xiang)意大(da)(da)(da)利ATOS葉片(pian)(pian)泵(beng)分為配流與(yu)軸(zhou)配流兩大(da)(da)(da)類。閥(fa)(fa)配流徑(jing)(jing)向(xiang)葉片(pian)(pian)泵(beng)存在故障率高、效率低等缺(que)點。上70、80年代發展的(de)(de)軸(zhou)配流徑(jing)(jing)向(xiang)柱塞(sai)泵(beng)克服了閥(fa)(fa)配流徑(jing)(jing)向(xiang)葉片(pian)(pian)泵(beng)的(de)(de)不足。由于徑(jing)(jing)向(xiang)泵(beng)結構上的(de)(de)特點,陜定(ding)了軸(zhou)配流徑(jing)(jing)向(xiang)葉片(pian)(pian)泵(beng)比軸(zhou)向(xiang)葉片(pian)(pian)泵(beng)耐沖擊、壽命長、控(kong)制(zhi)精度(du)高。變(bian)(bian)量(liang)(liang)行(xing)程短(duan)泵(beng)的(de)(de)變(bian)(bian)量(liang)(liang)是在變(bian)(bian)量(liang)(liang)柱塞(sai)和限(xian)位柱塞(sai)作用下,改(gai)變(bian)(bian)定(ding)子的(de)(de)偏心距實(shi)現(xian)的(de)(de),而定(ding)于的(de)(de)zui大(da)(da)(da)偏心距為 5—9mm(根據(ju)排量(liang)(liang)大(da)(da)(da)小不同(tong)),變(bian)(bian)量(liang)(liang)行(xing)程很短(duan)。且變(bian)(bian)量(liang)(liang)機構設計為高壓操(cao)縱(zong),由控(kong)制(zhi)閥(fa)(fa)進行(xing)控(kong)制(zhi)。故該泵(beng)的(de)(de)響應(ying)速度(du)快(kuai)。徑(jing)(jing)向(xiang)結構設計克服了如軸(zhou)向(xiang)葉片(pian)(pian)泵(beng)滑靴偏磨的(de)(de)問題。使其抗沖擊能力(li)大(da)(da)(da)幅度(du)提高。 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 |
