一、單作(zuo)用葉片泵的工作(zuo)原理(li): ATOS葉(xie)片(pian)(pian)泵由轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)1、定(ding)子(zi)(zi)(zi)(zi)(zi)2、葉(xie)片(pian)(pian)3、配油(you)(you)盤和(he)端蓋(gai)等部件所組成。定(ding)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)(de)內表面(mian)是圓柱形孔。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)和(he)定(ding)子(zi)(zi)(zi)(zi)(zi)之間(jian)存在著(zhu)偏心。葉(xie)片(pian)(pian)在轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)(de)槽(cao)內可靈活滑(hua)動,在轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)動時的(de)(de)(de)(de)離(li)心力(li)(li)以(yi)及通入(ru)葉(xie)片(pian)(pian)根部壓(ya)力(li)(li)油(you)(you)的(de)(de)(de)(de)作(zuo)用(yong)(yong)下,葉(xie)片(pian)(pian)頂部貼緊在定(ding)子(zi)(zi)(zi)(zi)(zi)內表面(mian)上,于是兩相(xiang)鄰葉(xie)片(pian)(pian)、配油(you)(you)盤、定(ding)子(zi)(zi)(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)間(jian)便形成了一(yi)個個密(mi)(mi)封(feng)的(de)(de)(de)(de)工(gong)作(zuo)腔(qiang)。當轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)按逆(ni)時針方向(xiang)(xiang)旋轉(zhuan)(zhuan)(zhuan)時,圖右側的(de)(de)(de)(de)葉(xie)片(pian)(pian)向(xiang)(xiang)外(wai)伸出,密(mi)(mi)封(feng)工(gong)作(zuo)腔(qiang)容積(ji)逐(zhu)漸增大,產生真(zhen)空,于是通過(guo)吸油(you)(you)口(kou)(kou)6和(he)配油(you)(you)盤5上窗口(kou)(kou)將油(you)(you)吸入(ru)。而(er)在圖的(de)(de)(de)(de)左側。葉(xie)片(pian)(pian)往里縮(suo)進,密(mi)(mi)封(feng)腔(qiang)的(de)(de)(de)(de)容積(ji)逐(zhu)漸縮(suo)小,密(mi)(mi)封(feng)腔(qiang)中的(de)(de)(de)(de)油(you)(you)液經配油(you)(you)盤另一(yi)窗口(kou)(kou)和(he)壓(ya)油(you)(you)口(kou)(kou)1被壓(ya)出而(er)輸出到系統中去。這種泵在轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)一(yi)轉(zhuan)(zhuan)(zhuan)過(guo)程中,吸油(you)(you)壓(ya)油(you)(you)各一(yi)次,故(gu)稱單(dan)作(zuo)用(yong)(yong)泵。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)受(shou)到徑向(xiang)(xiang)液壓(ya)不平衡(heng)作(zuo)用(yong)(yong)力(li)(li),故(gu)又稱非平衡(heng)式泵,其軸承負載較大。改(gai)變(bian)定(ding)子(zi)(zi)(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)間(jian)的(de)(de)(de)(de)偏心量,便可改(gai)變(bian)泵的(de)(de)(de)(de)排量,故(gu)這種泵都是變(bian)量泵。 二、雙作用葉片泵(beng)的工作原理: ATOS葉(xie)(xie)片泵(beng)(beng)的作(zuo)(zuo)(zuo)用(yong)(yong)原(yuan)理和(he)(he)(he)單作(zuo)(zuo)(zuo)用(yong)(yong)葉(xie)(xie)片泵(beng)(beng)相似,不同之(zhi)處只在于定(ding)子(zi)表面是由(you)兩(liang)(liang)(liang)(liang)段(duan)(duan)長半徑圓(yuan)弧、兩(liang)(liang)(liang)(liang)段(duan)(duan)短半徑圓(yuan)弧和(he)(he)(he)四段(duan)(duan)過渡曲(qu)線八個(ge)部分組成,且定(ding)子(zi)和(he)(he)(he)轉子(zi)是同心(xin)的。在圖示轉子(zi)順(shun)時針方向(xiang)旋轉的情況下,密(mi)封(feng)工作(zuo)(zuo)(zuo)腔的容積在左上角(jiao)(jiao)和(he)(he)(he)右(you)下角(jiao)(jiao)處逐漸(jian)增大,為吸油(you)(you)(you)(you)區(qu),在左下角(jiao)(jiao)和(he)(he)(he)右(you)上角(jiao)(jiao)處逐漸(jian)減小,為壓油(you)(you)(you)(you)區(qu);吸油(you)(you)(you)(you)區(qu)和(he)(he)(he)壓油(you)(you)(you)(you)區(qu)之(zhi)間有(you)一段(duan)(duan)封(feng)油(you)(you)(you)(you)區(qu)把它(ta)們(men)隔開。這種泵(beng)(beng)的轉子(zi)每(mei)轉一轉,每(mei)個(ge)密(mi)封(feng)工作(zuo)(zuo)(zuo)腔完成吸油(you)(you)(you)(you)和(he)(he)(he)壓油(you)(you)(you)(you)動作(zuo)(zuo)(zuo)各兩(liang)(liang)(liang)(liang)次,所以稱為雙作(zuo)(zuo)(zuo)用(yong)(yong)葉(xie)(xie)片泵(beng)(beng)。泵(beng)(beng)的兩(liang)(liang)(liang)(liang)個(ge)吸油(you)(you)(you)(you)區(qu)和(he)(he)(he)兩(liang)(liang)(liang)(liang)個(ge)壓油(you)(you)(you)(you)區(qu)是徑向(xiang)對稱的,作(zuo)(zuo)(zuo)用(yong)(yong)在轉子(zi)上的液壓力(li)徑向(xiang)平衡,所以又(you)稱為平衡式葉(xie)(xie)片泵(beng)(beng)。 雙作(zuo)(zuo)用葉(xie)片泵的瞬時流(liu)量是脈(mo)動的,當(dang)葉(xie)片數為(wei)4的倍數時脈(mo)動率小。為(wei)此,雙作(zuo)(zuo)用葉(xie)片泵的葉(xie)片數一般都取12或16。 意大利進口ATOS葉片泵部分型號: PFE-31028/1DV PFE-31036/1DT PFE-31036/1DU 20 PFE-31036/1DV 20 PFE-31036/1DW PFE-31044/1DT 20 PFE-31044/1DU 20 PFE-31044/1DV 20 PFE-32028/3DT 20 PFE-32028/3DV 20 PFE-32036/3DT PFE-41037/1DU 20 PFE-41045/1DT PFE-41045/1DU 20 PFE-41045/1DW 20 PFE-41056/1DT PFE-41056/1DU 20 PFE-41056/1DV 20 PFE-41056/1DW 20 PFE-41070/1DT PFE-41070/1DV 20 PFE-41070/2DT 20 PFE-41070/2DV 20 PFE-41085/1DT 20 PFE-41085/1DW 20 PFE-42045/3DW 20 PFE-42056/3DU 20 PFE-42070/3DT 20 PFE-42070/3DU PFE-42070/3DW 20 PFE-42070/7DV PFE-51090/1DT 23 PFE-51090/1DU PFE-51110/1DT 23 PFE-51110/1DU 23 PFE-51110/3DT 23 PFE-51129/1DT PFE-51150/1DT PFE-51150/3DV PFE-52090/3DT 31 PFE-52110/3DT 31 |
