詳細(xì)介紹
威格士(VICKERS)是伊頓集團(tuán)流體動力部門旗下的一個的液壓品牌,,深圳市冠宇液壓設(shè)備有限公司其主要產(chǎn)品包括液壓泵、馬達(dá),、油缸,、液壓閥等,。伊頓的流體動力產(chǎn)品應(yīng)用廣泛,,包括土方機械,、農(nóng)業(yè)、建筑,、航空,、采礦、林業(yè),、公共設(shè)施和物料搬運,。伊頓是的多元化工業(yè)產(chǎn)品制造商,在的工業(yè)領(lǐng)域享有技術(shù)良好,、質(zhì)量可靠的聲譽,。在6大洲超過125個國家擁有5萬5千名員工。年銷售額為98億美元,。產(chǎn)品涉及汽車,、卡車、重型設(shè)備,、民航,、國防軍事、居住,、電訊和數(shù)據(jù)傳輸,、工業(yè)設(shè)備和公共設(shè)施、商業(yè)機構(gòu)和*,、以及運動和娛樂的各個領(lǐng)域,。
泵由轉(zhuǎn)子2、定子3,、葉片4,、配油盤和端蓋等部件所組成。定子的內(nèi)表面是圓柱形孔,。轉(zhuǎn)子和定子之間存在著偏心,。葉片在轉(zhuǎn)子的槽內(nèi)可靈活滑動,在轉(zhuǎn)子轉(zhuǎn)動時的離心力以及通入葉片根部壓力油的作用下,,葉片頂部貼緊在定子內(nèi)表面上,,于是兩相鄰葉片、配油盤,、定子和轉(zhuǎn)子間便形成了一個個密封的工作腔,。當(dāng)轉(zhuǎn)子按逆時針方向旋轉(zhuǎn)時,圖右側(cè)的葉片向外伸出,,密封工作腔容積逐漸增大,,產(chǎn)生真空,于是通過吸油口6和配油盤5上窗口將油吸入,。而在圖的左側(cè),。葉片往里縮進(jìn),,密封腔的容積逐漸縮小,密封腔中的油液經(jīng)配油盤另一窗口和壓油口1被壓出而輸出到系統(tǒng)中去,。這種泵在轉(zhuǎn)子轉(zhuǎn)一轉(zhuǎn)過程中,,吸油壓油各一次,故稱單作用泵,。轉(zhuǎn)子受到徑向液壓不平衡作用力,,故又稱非平衡式泵,其軸承負(fù)載較大,。改變定子和轉(zhuǎn)子間的偏心量,,便可改變泵的排量,故這種泵都是變量泵,。
二,、雙作用Vickers葉片泵的工作原理
它的作用原理和單作用Vickers葉片泵相似,不同之處只在于定子表面是由兩段長半徑圓弧,、兩段短半徑圓弧和四段過渡曲線八個部分組成,,且定子和轉(zhuǎn)子是同心的。在圖示轉(zhuǎn)子順時針方向旋轉(zhuǎn)的情況下,,密封工作腔的容積在左上角和右下角處逐漸增大,,為吸油區(qū),在左下角和右上角處逐漸減小,,為壓油區(qū),;吸油區(qū)和壓油區(qū)之間有一段封油區(qū)把它們隔開。這種泵的轉(zhuǎn)子每轉(zhuǎn)一轉(zhuǎn),,每個密封工作腔完成吸油和壓油動作各兩次,,所以稱為雙作用Vickers葉片泵。泵的兩個吸油區(qū)和兩個壓油區(qū)是徑向?qū)ΨQ的,,作用在轉(zhuǎn)子上的液壓力徑向平衡,,所以又稱為平衡式Vickers葉片泵。
雙作用Vickers葉片泵的瞬時流量是脈動的,,當(dāng)葉片數(shù)為4的倍數(shù)時脈動率小,。為此,雙作用Vickers葉片泵的葉片數(shù)一般都取12或16,。

Vickers葉片泵的管理要點除需防干轉(zhuǎn)和過載,、防吸入空氣和吸入真空度過大外,,還應(yīng)注意:
1.泵轉(zhuǎn)向改變,,則其吸排方向也改變Vickers葉片泵都有規(guī)定的轉(zhuǎn)向,不允許反,。因為轉(zhuǎn)子葉槽有傾斜,,葉片有倒角,葉片底部與排油腔通,,配油盤上的節(jié)流槽和吸,、排口是按既定轉(zhuǎn)向設(shè)計??赡孓D(zhuǎn)的Vickers葉片泵必須專門設(shè)計,。
2.Vickers葉片泵裝配配油盤與定子用定位銷正確定位,葉片,、轉(zhuǎn)子,、配油盤都不得裝反,定子內(nèi)表面吸入?yún)^(qū)部分zui易磨損,,必要時可將其翻轉(zhuǎn)安裝,,以使原吸入?yún)^(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用。
3.拆裝注意工作表面清潔,,工作時油液應(yīng)很好過濾,。
4.葉片在葉槽中的間隙太大會使漏泄增加,,太小則葉片不能自由伸縮,,會導(dǎo)致工作失常。
5.Vickers葉片泵的軸向間隙對ηv影響很大,。
1)小型泵-0.015~0.03mm
2)中型泵-0.02~0.045mm
6.油液的溫度和粘度一般不宜超過55℃,,粘度要求在17~37mm2/s之間。粘度太大則吸油困難,;粘度太小則漏泄嚴(yán)重,。
作為泵產(chǎn)品,Vickers葉片泵更多地指滑片泵,。只要你有興趣在 搜索發(fā)現(xiàn),,Vickers葉片泵幾乎全部指滑片泵。
