意大利進口ATOS葉片泵PFE-41045/1DT 一、單作用葉片泵(beng)的工作原理： ATOS葉片(pian)(pian)(pian)泵(beng)(beng)(beng)(beng)由轉子(zi)(zi)(zi)(zi)1、定(ding)子(zi)(zi)(zi)(zi)2、葉片(pian)(pian)(pian)3、配(pei)(pei)(pei)油(you)盤和(he)端蓋等(deng)部件所組成。定(ding)子(zi)(zi)(zi)(zi)的(de)內(nei)表(biao)面(mian)是圓柱(zhu)形孔。轉子(zi)(zi)(zi)(zi)和(he)定(ding)子(zi)(zi)(zi)(zi)之間(jian)存在(zai)(zai)著偏(pian)心(xin)。葉片(pian)(pian)(pian)在(zai)(zai)轉子(zi)(zi)(zi)(zi)的(de)槽內(nei)可靈活滑動(dong)，在(zai)(zai)轉子(zi)(zi)(zi)(zi)轉動(dong)時(shi)的(de)離心(xin)力以及(ji)通入葉片(pian)(pian)(pian)根部壓(ya)(ya)力油(you)的(de)作(zuo)用下，葉片(pian)(pian)(pian)頂部貼緊(jin)在(zai)(zai)定(ding)子(zi)(zi)(zi)(zi)內(nei)表(biao)面(mian)上(shang)，于是兩(liang)相鄰葉片(pian)(pian)(pian)、配(pei)(pei)(pei)油(you)盤、定(ding)子(zi)(zi)(zi)(zi)和(he)轉子(zi)(zi)(zi)(zi)間(jian)便形成了一(yi)個(ge)個(ge)密(mi)(mi)封(feng)(feng)的(de)工作(zuo)腔。當轉子(zi)(zi)(zi)(zi)按逆(ni)時(shi)針方向旋轉時(shi)，圖右側的(de)葉片(pian)(pian)(pian)向外(wai)伸出，密(mi)(mi)封(feng)(feng)工作(zuo)腔容(rong)積逐漸增大，產生真(zhen)空(kong)，于是通過(guo)吸油(you)口(kou)6和(he)配(pei)(pei)(pei)油(you)盤5上(shang)窗口(kou)將(jiang)油(you)吸入。而在(zai)(zai)圖的(de)左(zuo)側。葉片(pian)(pian)(pian)往里縮進，密(mi)(mi)封(feng)(feng)腔的(de)容(rong)積逐漸縮小，密(mi)(mi)封(feng)(feng)腔中的(de)油(you)液經配(pei)(pei)(pei)油(you)盤另(ling)一(yi)窗口(kou)和(he)壓(ya)(ya)油(you)口(kou)1被(bei)壓(ya)(ya)出而輸出到系統中去。這種泵(beng)(beng)(beng)(beng)在(zai)(zai)轉子(zi)(zi)(zi)(zi)轉一(yi)轉過(guo)程中，吸油(you)壓(ya)(ya)油(you)各一(yi)次，故稱(cheng)單作(zuo)用泵(beng)(beng)(beng)(beng)。轉子(zi)(zi)(zi)(zi)受到徑向液壓(ya)(ya)不平衡作(zuo)用力，故又(you)稱(cheng)非平衡式(shi)泵(beng)(beng)(beng)(beng)，其軸承負載較大。改變(bian)定(ding)子(zi)(zi)(zi)(zi)和(he)轉子(zi)(zi)(zi)(zi)間(jian)的(de)偏(pian)心(xin)量(liang)(liang)，便可改變(bian)泵(beng)(beng)(beng)(beng)的(de)排量(liang)(liang)，故這種泵(beng)(beng)(beng)(beng)都是變(bian)量(liang)(liang)泵(beng)(beng)(beng)(beng)。 二、雙作用葉片泵(beng)的(de)工(gong)作原理(li)： ATOS葉(xie)(xie)片泵(beng)的(de)(de)作(zuo)(zuo)用(yong)原(yuan)理和單(dan)作(zuo)(zuo)用(yong)葉(xie)(xie)片泵(beng)相似，不同之處只在(zai)于定子(zi)(zi)表面是(shi)(shi)由兩(liang)段長半徑圓(yuan)弧、兩(liang)段短(duan)半徑圓(yuan)弧和四段過(guo)渡曲線八個(ge)(ge)部分組成，且定子(zi)(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)(zi)是(shi)(shi)同心的(de)(de)。在(zai)圖示轉(zhuan)(zhuan)(zhuan)子(zi)(zi)順時針方向(xiang)旋(xuan)轉(zhuan)(zhuan)(zhuan)的(de)(de)情況下，密(mi)封工作(zuo)(zuo)腔(qiang)的(de)(de)容積在(zai)左上角(jiao)和右下角(jiao)處逐(zhu)漸增(zeng)大，為(wei)吸(xi)油(you)(you)(you)區(qu)，在(zai)左下角(jiao)和右上角(jiao)處逐(zhu)漸減小，為(wei)壓(ya)油(you)(you)(you)區(qu)；吸(xi)油(you)(you)(you)區(qu)和壓(ya)油(you)(you)(you)區(qu)之間有一段封油(you)(you)(you)區(qu)把它們隔開。這種泵(beng)的(de)(de)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)每轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)，每個(ge)(ge)密(mi)封工作(zuo)(zuo)腔(qiang)完成吸(xi)油(you)(you)(you)和壓(ya)油(you)(you)(you)動(dong)作(zuo)(zuo)各兩(liang)次(ci)，所以稱(cheng)為(wei)雙作(zuo)(zuo)用(yong)葉(xie)(xie)片泵(beng)。泵(beng)的(de)(de)兩(liang)個(ge)(ge)吸(xi)油(you)(you)(you)區(qu)和兩(liang)個(ge)(ge)壓(ya)油(you)(you)(you)區(qu)是(shi)(shi)徑向(xiang)對稱(cheng)的(de)(de)，作(zuo)(zuo)用(yong)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)上的(de)(de)液壓(ya)力(li)徑向(xiang)平衡，所以又稱(cheng)為(wei)平衡式(shi)葉(xie)(xie)片泵(beng)。 雙作用葉(xie)片泵的瞬時(shi)流量是脈(mo)動的，當葉(xie)片數為(wei)4的倍(bei)數時(shi)脈(mo)動率小(xiao)。為(wei)此，雙作用葉(xie)片泵的葉(xie)片數一般都取12或16。 ATOS葉片泵部分型號： PFE-31028/1DV
