Eaton V10和(he)V20葉片泵具有(you)大(da)范(fan)圍的(de)排量，設計用(yong)于各種(zhong)低壓(ya)至中(zhong)壓(ya)的(de)移動和(he)工(gong)業應用(yong)。它們廣(guang)泛用(yong)作復雜工(gong)業系統的(de)先導泵和(he)輔(fu)助泵，在(zai)重(zhong)型卡(ka)車和(he)州際客(ke)車中(zhong)也很常(chang)見。

VICKERS單作用葉片泵的工(gong)作原理(li)

泵(beng)由(you)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)1、定(ding)(ding)子(zi)(zi)(zi)(zi)(zi)2、葉片(pian)3、配(pei)油(you)盤和(he)端蓋(gai)等部件所組成。定(ding)(ding)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)(de)(de)內表面(mian)(mian)是圓(yuan)柱形孔。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)和(he)定(ding)(ding)子(zi)(zi)(zi)(zi)(zi)之間(jian)存在(zai)(zai)著偏(pian)心(xin)。葉片(pian)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)(de)(de)槽內可靈活滑動，在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)動時(shi)的(de)(de)(de)(de)(de)離心(xin)力以及通(tong)入葉片(pian)根部壓(ya)(ya)力油(you)的(de)(de)(de)(de)(de)作(zuo)用下，葉片(pian)頂部貼(tie)緊在(zai)(zai)定(ding)(ding)子(zi)(zi)(zi)(zi)(zi)內表面(mian)(mian)上，于是兩(liang)相鄰葉片(pian)、配(pei)油(you)盤、定(ding)(ding)子(zi)(zi)(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)間(jian)便形成了一個個密封(feng)(feng)(feng)的(de)(de)(de)(de)(de)工作(zuo)腔(qiang)。當轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)按(an)逆時(shi)針方向旋轉(zhuan)(zhuan)(zhuan)(zhuan)時(shi)，圖右(you)側的(de)(de)(de)(de)(de)葉片(pian)向外伸出，密封(feng)(feng)(feng)工作(zuo)腔(qiang)容(rong)積逐漸增大，產生真空，于是通(tong)過(guo)(guo)吸(xi)油(you)口(kou)6和(he)配(pei)油(you)盤5上窗口(kou)將油(you)吸(xi)入。而(er)在(zai)(zai)圖的(de)(de)(de)(de)(de)左側。葉片(pian)往里縮進(jin)，密封(feng)(feng)(feng)腔(qiang)的(de)(de)(de)(de)(de)容(rong)積逐漸縮小，密封(feng)(feng)(feng)腔(qiang)中(zhong)(zhong)的(de)(de)(de)(de)(de)油(you)液經配(pei)油(you)盤另一窗口(kou)和(he)壓(ya)(ya)油(you)口(kou)1被(bei)壓(ya)(ya)出而(er)輸出到(dao)系統(tong)中(zhong)(zhong)去。這(zhe)種泵(beng)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)(zhuan)過(guo)(guo)程中(zhong)(zhong)，吸(xi)油(you)壓(ya)(ya)油(you)各一次，故(gu)稱(cheng)單作(zuo)用泵(beng)。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)受到(dao)徑向液壓(ya)(ya)不(bu)平衡(heng)(heng)作(zuo)用力，故(gu)又(you)稱(cheng)非(fei)平衡(heng)(heng)式泵(beng)，其軸承(cheng)負載較大。改變定(ding)(ding)子(zi)(zi)(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)間(jian)的(de)(de)(de)(de)(de)偏(pian)心(xin)量，便可改變泵(beng)的(de)(de)(de)(de)(de)排量，故(gu)這(zhe)種泵(beng)都是變量泵(beng)。

VICKERS葉(xie)(xie)片(pian)泵在(zai)(zai)采用(yong)本文所提(ti)出的(de)(de)改進方案后，利用(yong)相對(dui)(dui)運(yun)動(dong)(dong)，將轉子(zi)固定(ding)(ding)(ding)(ding)，而(er)定(ding)(ding)(ding)(ding)子(zi)旋轉，滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)在(zai)(zai)葉(xie)(xie)片(pian)底部高壓油的(de)(de)作用(yong)下(xia)，緊壓在(zai)(zai)定(ding)(ding)(ding)(ding)子(zi)內(nei)表面(mian)(mian)，又由于滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)和(he)(he)(he)(he)葉(xie)(xie)片(pian)凹槽是(shi)(shi)間(jian)隙配合，在(zai)(zai)運(yun)轉的(de)(de)過程中會有吸壓油區和(he)(he)(he)(he)端(duan)面(mian)(mian)泄漏的(de)(de)油液(ye)(ye)進入其中形成(cheng)動(dong)(dong)壓油膜(mo)，使滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)和(he)(he)(he)(he)葉(xie)(xie)片(pian)間(jian)形成(cheng)液(ye)(ye)體動(dong)(dong)力潤滑，滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)和(he)(he)(he)(he)葉(xie)(xie)片(pian)凹槽間(jian)的(de)(de)摩擦(ca)也很(hen)小。這樣(yang)在(zai)(zai)定(ding)(ding)(ding)(ding)子(zi)轉動(dong)(dong)的(de)(de)情況下(xia)，每個滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)相對(dui)(dui)固定(ding)(ding)(ding)(ding)在(zai)(zai)某個位置(zhi)，從而(er)使滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)實現滾(gun)(gun)(gun)動(dong)(dong)。使滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)和(he)(he)(he)(he)定(ding)(ding)(ding)(ding)子(zi)內(nei)表面(mian)(mian)的(de)(de)滑動(dong)(dong)摩擦(ca)變為(wei)滾(gun)(gun)(gun)動(dong)(dong)摩擦(ca)，滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)和(he)(he)(he)(he)葉(xie)(xie)片(pian)凹槽之間(jian)形成(cheng)動(dong)(dong)壓油膜(mo)，從而(er)是(shi)(shi)摩擦(ca)狀況大大減小。由于滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)與定(ding)(ding)(ding)(ding)子(zi)內(nei)表面(mian)(mian)之間(jian)為(wei)線接(jie)觸(chu)，單面(mian)(mian)后傾葉(xie)(xie)片(pian)與定(ding)(ding)(ding)(ding)子(zi)內(nei)表面(mian)(mian)也為(wei)線接(jie)觸(chu)，滾(gun)(gun)(gun)針(zhen)(zhen)(zhen)長度可以設(she)計成(cheng)等(deng)于葉(xie)(xie)片(pian)寬度，這樣(yang)就不存在(zai)(zai)在(zai)(zai)改進后增大了泄露的(de)(de)問題。
