ATOS葉(xie)片泵是活塞(sai)或柱(zhu)塞(sai)的往復運(yun)動方向與(yu)(yu)缸體中(zhong)心(xin)軸(zhou)平(ping)(ping)行(xing)的葉(xie)片泵。軸(zhou)向葉(xie)片泵是利(li)用(yong)與(yu)(yu)傳(chuan)動軸(zhou)平(ping)(ping)行(xing)的柱(zhu)塞(sai)在柱(zhu)塞(sai)孔內往復運(yun)動所產生(sheng)的容(rong)積(ji)變化來進行(xing)工(gong)(gong)(gong)作的。由(you)于(yu)柱(zhu)塞(sai)和柱(zhu)塞(sai)孔都是圓形零(ling)件,加工(gong)(gong)(gong)時可以達(da)到很高(gao)的精(jing)度配合,因此(ci)容(rong)積(ji)效率(lv)高(gao),運(yun)轉平(ping)(ping)穩,流(liu)量均勻性好,噪聲低,工(gong)(gong)(gong)作壓力高(gao)等優點,但(dan)對液壓油的污染較敏(min)感,結(jie)構較復雜,造價(jia)較高(gao)。 ATOS直軸斜盤式(shi)葉片泵(beng) 直軸斜盤式柱塞泵(beng)分為壓(ya)(ya)(ya)(ya)(ya)力供油(you)型(xing)的(de)自(zi)吸(xi)(xi)油(you)型(xing)兩種。壓(ya)(ya)(ya)(ya)(ya)力供油(you)型(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)大都采用有(you)氣(qi)壓(ya)(ya)(ya)(ya)(ya)的(de)油(you)箱(xiang),也(ye)有(you)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)本(ben)身帶有(you)補(bu)油(you)分泵(beng)向液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)進油(you)口提供壓(ya)(ya)(ya)(ya)(ya)力油(you)的(de)。自(zi)吸(xi)(xi)油(you)型(xing)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)的(de)自(zi)吸(xi)(xi)油(you)能力很強,無需(xu)外力供油(you)。靠氣(qi)壓(ya)(ya)(ya)(ya)(ya)供油(you)的(de)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)箱(xiang),在每次啟(qi)動機器后,必須(xu)等液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)漬箱(xiang)達(da)到使用氣(qi)壓(ya)(ya)(ya)(ya)(ya)后,才能操作機械。如液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)箱(xiang)的(de)氣(qi)壓(ya)(ya)(ya)(ya)(ya)不(bu)足時就擔任機器,會(hui)對(dui)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)內(nei)的(de)與滑鞭造成拉(la)脫(tuo)現象(xiang),出會(hui)造成泵(beng)體內(nei)回程板(ban)與壓(ya)(ya)(ya)(ya)(ya)板(ban)的(de)非(fei)正(zheng)常(chang)磨損。 ATOS徑向意大利葉片泵 徑(jing)向(xiang)意大利ATOS葉片(pian)(pian)泵(beng)(beng)分為(wei)配(pei)流(liu)與軸(zhou)配(pei)流(liu)兩(liang)大類。閥配(pei)流(liu)徑(jing)向(xiang)葉片(pian)(pian)泵(beng)(beng)存在故障率高、效率低等缺點。上70、80年(nian)代(dai)發展的(de)軸(zhou)配(pei)流(liu)徑(jing)向(xiang)柱(zhu)塞(sai)泵(beng)(beng)克服了閥配(pei)流(liu)徑(jing)向(xiang)葉片(pian)(pian)泵(beng)(beng)的(de)不足(zu)。由于徑(jing)向(xiang)泵(beng)(beng)結構上的(de)特點,陜定(ding)了軸(zhou)配(pei)流(liu)徑(jing)向(xiang)葉片(pian)(pian)泵(beng)(beng)比軸(zhou)向(xiang)葉片(pian)(pian)泵(beng)(beng)耐沖擊(ji)、壽命(ming)長、控(kong)(kong)制精度高。變量(liang)行(xing)程短(duan)泵(beng)(beng)的(de)變量(liang)是在變量(liang)柱(zhu)塞(sai)和限位柱(zhu)塞(sai)作用下,改變定(ding)子的(de)偏(pian)(pian)心距(ju)實現的(de),而定(ding)于的(de)zui大偏(pian)(pian)心距(ju)為(wei) 5—9mm(根據排(pai)量(liang)大小不同),變量(liang)行(xing)程很短(duan)。且變量(liang)機構設計為(wei)高壓操縱(zong),由控(kong)(kong)制閥進行(xing)控(kong)(kong)制。故該泵(beng)(beng)的(de)響應速(su)度快。徑(jing)向(xiang)結構設計克服了如軸(zhou)向(xiang)葉片(pian)(pian)泵(beng)(beng)滑靴偏(pian)(pian)磨的(de)問題。使(shi)其抗沖擊(ji)能(neng)力大幅度提高。 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 |
