一、單作用葉片泵的(de)工作原(yuan)理(li)： ATOS葉(xie)(xie)(xie)片(pian)(pian)泵(beng)(beng)(beng)由轉(zhuan)子(zi)1、定(ding)子(zi)2、葉(xie)(xie)(xie)片(pian)(pian)3、配(pei)油(you)(you)(you)盤和(he)(he)端蓋等(deng)部件(jian)所組成(cheng)。定(ding)子(zi)的(de)(de)內表面是圓柱(zhu)形孔(kong)。轉(zhuan)子(zi)和(he)(he)定(ding)子(zi)之(zhi)間(jian)存在(zai)著偏(pian)心(xin)。葉(xie)(xie)(xie)片(pian)(pian)在(zai)轉(zhuan)子(zi)的(de)(de)槽內可靈活滑動，在(zai)轉(zhuan)子(zi)轉(zhuan)動時(shi)的(de)(de)離心(xin)力以及通(tong)入葉(xie)(xie)(xie)片(pian)(pian)根部壓(ya)力油(you)(you)(you)的(de)(de)作用(yong)(yong)下，葉(xie)(xie)(xie)片(pian)(pian)頂(ding)部貼緊(jin)在(zai)定(ding)子(zi)內表面上(shang)，于是兩相(xiang)鄰葉(xie)(xie)(xie)片(pian)(pian)、配(pei)油(you)(you)(you)盤、定(ding)子(zi)和(he)(he)轉(zhuan)子(zi)間(jian)便形成(cheng)了一(yi)個個密封的(de)(de)工作腔。當轉(zhuan)子(zi)按逆時(shi)針方向旋轉(zhuan)時(shi)，圖(tu)右側的(de)(de)葉(xie)(xie)(xie)片(pian)(pian)向外伸出(chu)，密封工作腔容積逐(zhu)漸(jian)增大，產生真(zhen)空，于是通(tong)過吸(xi)油(you)(you)(you)口(kou)(kou)6和(he)(he)配(pei)油(you)(you)(you)盤5上(shang)窗(chuang)口(kou)(kou)將油(you)(you)(you)吸(xi)入。而在(zai)圖(tu)的(de)(de)左(zuo)側。葉(xie)(xie)(xie)片(pian)(pian)往里縮進，密封腔的(de)(de)容積逐(zhu)漸(jian)縮小(xiao)，密封腔中(zhong)的(de)(de)油(you)(you)(you)液經配(pei)油(you)(you)(you)盤另(ling)一(yi)窗(chuang)口(kou)(kou)和(he)(he)壓(ya)油(you)(you)(you)口(kou)(kou)1被壓(ya)出(chu)而輸出(chu)到系統中(zhong)去(qu)。這種泵(beng)(beng)(beng)在(zai)轉(zhuan)子(zi)轉(zhuan)一(yi)轉(zhuan)過程中(zhong)，吸(xi)油(you)(you)(you)壓(ya)油(you)(you)(you)各一(yi)次，故稱(cheng)單(dan)作用(yong)(yong)泵(beng)(beng)(beng)。轉(zhuan)子(zi)受到徑向液壓(ya)不(bu)平(ping)衡(heng)作用(yong)(yong)力，故又稱(cheng)非平(ping)衡(heng)式(shi)泵(beng)(beng)(beng)，其軸承負載較大。改變定(ding)子(zi)和(he)(he)轉(zhuan)子(zi)間(jian)的(de)(de)偏(pian)心(xin)量，便可改變泵(beng)(beng)(beng)的(de)(de)排(pai)量，故這種泵(beng)(beng)(beng)都是變量泵(beng)(beng)(beng)。 二、雙(shuang)作用(yong)葉片泵(beng)的工作原(yuan)理(li)： ATOS葉(xie)片(pian)泵(beng)(beng)(beng)(beng)的(de)作(zuo)用(yong)原理和(he)單(dan)作(zuo)用(yong)葉(xie)片(pian)泵(beng)(beng)(beng)(beng)相(xiang)似，不同之處(chu)只(zhi)在(zai)(zai)于定(ding)子(zi)(zi)表面是(shi)由(you)兩(liang)(liang)段(duan)長(chang)半(ban)徑圓(yuan)弧(hu)、兩(liang)(liang)段(duan)短(duan)半(ban)徑圓(yuan)弧(hu)和(he)四段(duan)過(guo)渡曲線八(ba)個部分組成，且(qie)定(ding)子(zi)(zi)和(he)轉子(zi)(zi)是(shi)同心(xin)的(de)。在(zai)(zai)圖(tu)示轉子(zi)(zi)順時針方向(xiang)旋轉的(de)情(qing)況下，密封(feng)工(gong)作(zuo)腔的(de)容(rong)積在(zai)(zai)左上(shang)角(jiao)和(he)右(you)下角(jiao)處(chu)逐漸增(zeng)大(da)，為(wei)吸(xi)油(you)(you)(you)區(qu)(qu)，在(zai)(zai)左下角(jiao)和(he)右(you)上(shang)角(jiao)處(chu)逐漸減小，為(wei)壓(ya)油(you)(you)(you)區(qu)(qu)；吸(xi)油(you)(you)(you)區(qu)(qu)和(he)壓(ya)油(you)(you)(you)區(qu)(qu)之間有(you)一段(duan)封(feng)油(you)(you)(you)區(qu)(qu)把它們隔開。這種泵(beng)(beng)(beng)(beng)的(de)轉子(zi)(zi)每(mei)轉一轉，每(mei)個密封(feng)工(gong)作(zuo)腔完成吸(xi)油(you)(you)(you)和(he)壓(ya)油(you)(you)(you)動(dong)作(zuo)各兩(liang)(liang)次，所以稱為(wei)雙作(zuo)用(yong)葉(xie)片(pian)泵(beng)(beng)(beng)(beng)。泵(beng)(beng)(beng)(beng)的(de)兩(liang)(liang)個吸(xi)油(you)(you)(you)區(qu)(qu)和(he)兩(liang)(liang)個壓(ya)油(you)(you)(you)區(qu)(qu)是(shi)徑向(xiang)對稱的(de)，作(zuo)用(yong)在(zai)(zai)轉子(zi)(zi)上(shang)的(de)液(ye)壓(ya)力徑向(xiang)平衡(heng)，所以又稱為(wei)平衡(heng)式葉(xie)片(pian)泵(beng)(beng)(beng)(beng)。 雙作(zuo)用葉片泵(beng)的瞬時(shi)流量是脈動的，當葉片數(shu)為(wei)4的倍(bei)數(shu)時(shi)脈動率小。為(wei)此，雙作(zuo)用葉片泵(beng)的葉片數(shu)一(yi)般都取12或16。 意大利進口ATOS葉片泵部(bu)分型號(hao)： PFE-31028/1DV
