一、單作用葉(xie)片泵(beng)的工作原(yuan)理： ATOS葉(xie)片(pian)(pian)(pian)泵(beng)(beng)由轉(zhuan)(zhuan)(zhuan)子(zi)1、定(ding)子(zi)2、葉(xie)片(pian)(pian)(pian)3、配(pei)(pei)油(you)(you)(you)盤(pan)(pan)和(he)(he)端蓋等部件所組成。定(ding)子(zi)的(de)(de)內(nei)表面是圓(yuan)柱(zhu)形孔。轉(zhuan)(zhuan)(zhuan)子(zi)和(he)(he)定(ding)子(zi)之間(jian)(jian)存(cun)在(zai)(zai)著偏(pian)心(xin)。葉(xie)片(pian)(pian)(pian)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子(zi)的(de)(de)槽(cao)內(nei)可靈活(huo)滑(hua)動(dong)，在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)動(dong)時的(de)(de)離心(xin)力(li)以及(ji)通(tong)入(ru)葉(xie)片(pian)(pian)(pian)根部壓(ya)力(li)油(you)(you)(you)的(de)(de)作用(yong)下(xia)，葉(xie)片(pian)(pian)(pian)頂部貼(tie)緊在(zai)(zai)定(ding)子(zi)內(nei)表面上(shang)，于是兩相鄰葉(xie)片(pian)(pian)(pian)、配(pei)(pei)油(you)(you)(you)盤(pan)(pan)、定(ding)子(zi)和(he)(he)轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)(jian)便(bian)形成了一個個密封(feng)的(de)(de)工作腔(qiang)。當轉(zhuan)(zhuan)(zhuan)子(zi)按逆時針方向旋轉(zhuan)(zhuan)(zhuan)時，圖右側的(de)(de)葉(xie)片(pian)(pian)(pian)向外(wai)伸(shen)出，密封(feng)工作腔(qiang)容積(ji)(ji)逐漸增大，產(chan)生真空，于是通(tong)過吸(xi)油(you)(you)(you)口(kou)6和(he)(he)配(pei)(pei)油(you)(you)(you)盤(pan)(pan)5上(shang)窗(chuang)口(kou)將油(you)(you)(you)吸(xi)入(ru)。而在(zai)(zai)圖的(de)(de)左側。葉(xie)片(pian)(pian)(pian)往(wang)里(li)縮進(jin)，密封(feng)腔(qiang)的(de)(de)容積(ji)(ji)逐漸縮小，密封(feng)腔(qiang)中(zhong)的(de)(de)油(you)(you)(you)液經配(pei)(pei)油(you)(you)(you)盤(pan)(pan)另一窗(chuang)口(kou)和(he)(he)壓(ya)油(you)(you)(you)口(kou)1被壓(ya)出而輸出到(dao)系(xi)統中(zhong)去。這(zhe)種(zhong)泵(beng)(beng)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)過程(cheng)中(zhong)，吸(xi)油(you)(you)(you)壓(ya)油(you)(you)(you)各一次，故(gu)稱單作用(yong)泵(beng)(beng)。轉(zhuan)(zhuan)(zhuan)子(zi)受到(dao)徑向液壓(ya)不平衡作用(yong)力(li)，故(gu)又稱非平衡式(shi)泵(beng)(beng)，其軸(zhou)承負載較大。改(gai)變(bian)定(ding)子(zi)和(he)(he)轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)(jian)的(de)(de)偏(pian)心(xin)量(liang)，便(bian)可改(gai)變(bian)泵(beng)(beng)的(de)(de)排量(liang)，故(gu)這(zhe)種(zhong)泵(beng)(beng)都是變(bian)量(liang)泵(beng)(beng)。 二、雙(shuang)作(zuo)用葉片(pian)泵的工作(zuo)原理： ATOS葉(xie)(xie)片(pian)(pian)泵的(de)作(zuo)(zuo)(zuo)用原理和(he)(he)單作(zuo)(zuo)(zuo)用葉(xie)(xie)片(pian)(pian)泵相似，不同(tong)之(zhi)處(chu)(chu)只(zhi)在(zai)(zai)于定(ding)子(zi)表面(mian)是(shi)(shi)由兩(liang)段長半(ban)徑(jing)圓弧(hu)、兩(liang)段短半(ban)徑(jing)圓弧(hu)和(he)(he)四段過渡曲線八個(ge)(ge)部分組成(cheng)(cheng)，且定(ding)子(zi)和(he)(he)轉(zhuan)(zhuan)(zhuan)子(zi)是(shi)(shi)同(tong)心的(de)。在(zai)(zai)圖示轉(zhuan)(zhuan)(zhuan)子(zi)順時針方向旋轉(zhuan)(zhuan)(zhuan)的(de)情況下，密封(feng)工(gong)作(zuo)(zuo)(zuo)腔的(de)容積在(zai)(zai)左上角和(he)(he)右下角處(chu)(chu)逐漸增大，為(wei)吸(xi)(xi)油(you)區(qu)(qu)(qu)，在(zai)(zai)左下角和(he)(he)右上角處(chu)(chu)逐漸減小，為(wei)壓(ya)油(you)區(qu)(qu)(qu)；吸(xi)(xi)油(you)區(qu)(qu)(qu)和(he)(he)壓(ya)油(you)區(qu)(qu)(qu)之(zhi)間有一段封(feng)油(you)區(qu)(qu)(qu)把它(ta)們隔(ge)開。這種(zhong)泵的(de)轉(zhuan)(zhuan)(zhuan)子(zi)每轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)，每個(ge)(ge)密封(feng)工(gong)作(zuo)(zuo)(zuo)腔完成(cheng)(cheng)吸(xi)(xi)油(you)和(he)(he)壓(ya)油(you)動作(zuo)(zuo)(zuo)各兩(liang)次，所(suo)以稱(cheng)為(wei)雙作(zuo)(zuo)(zuo)用葉(xie)(xie)片(pian)(pian)泵。泵的(de)兩(liang)個(ge)(ge)吸(xi)(xi)油(you)區(qu)(qu)(qu)和(he)(he)兩(liang)個(ge)(ge)壓(ya)油(you)區(qu)(qu)(qu)是(shi)(shi)徑(jing)向對稱(cheng)的(de)，作(zuo)(zuo)(zuo)用在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子(zi)上的(de)液(ye)壓(ya)力徑(jing)向平衡(heng)，所(suo)以又(you)稱(cheng)為(wei)平衡(heng)式葉(xie)(xie)片(pian)(pian)泵。 雙作(zuo)(zuo)用葉(xie)片(pian)泵(beng)的瞬(shun)時(shi)流量是脈動的，當(dang)葉(xie)片(pian)數(shu)為(wei)4的倍數(shu)時(shi)脈動率小(xiao)。為(wei)此，雙作(zuo)(zuo)用葉(xie)片(pian)泵(beng)的葉(xie)片(pian)數(shu)一(yi)般都取(qu)12或(huo)16。 意大利進口ATOS葉片泵部(bu)分型號(hao)： PFE-31028/1DV
