意大利ATOS阿托斯葉片泵PFE型定量泵芯式葉片泵,具有高性能、低噪音、多用途及長壽命產品性能:3種基本形式泵芯*互換13種排量從16至150毫升/轉壓力從210至300barISO,SAE和DIN標準安裝一)ATOS雙葉片泵的工作原理二)ATOS單作用葉片泵的工作原理定子內腔型線是圓,轉子軸與定子偏心。逆時針回轉時,工作V右半轉增大,左半轉V 減小。從兩側配油盤的吸、排口吸排油。
兩相鄰葉片轉到吸、排油口間的密封區時,所接觸定子曲線不是與轉子同心的圓弧。密封區的圓心角略大于相鄰葉片所占圓心角。
葉間工作V 先略有增大,然后略有縮小,會產生困油現象,但不太嚴重。通過在排出口邊緣開三角形卸荷槽的方法即可解決。
定子、轉子和軸承受徑向力作用,屬非卸荷式葉片泵。工作P不宜太高,Q的均勻性也比雙作用差。
移動定子可改變偏心的方向及大小,可做成n恒定而Q可變的雙向或單向的無級變量泵。其中用得較多的是限壓式變量葉片泵。
1.定子(內腔型線):
1)兩段長半徑圓弧2)兩段短半徑圓弧3)四段過渡曲線2.轉子:
有若干葉槽,內有葉片。旋轉時,葉片受離心力及液壓力作用下,外頂定子內壁,并在槽內往復滑動。
3.配油盤:
在定子和轉子兩側,盤上有兩對吸、排口,在定子、轉子、葉片和配油盤之間形成若干個工作空間。
葉片由短轉向長半徑時,葉片間V增大,P降低,經配油盤吸油。葉片由長向短半徑時,葉片間V減小,經配油盤的排出口排油。當葉片位于密封區時,正好將吸、排口隔開,葉片間V不變,沒有困油問題。轉子轉一周,每工作V都吸、排兩次(雙作用泵)。
((三)內反饋限壓式ATOS變量葉片泵3_3_213.gif (12.47 KB) 13:38作用力Fx配油盤中線相對于定子中線順轉向偏轉了θ角。排油p對定子的作用力F便在定子中線方向產生分力Fx。
當Fx小于補償器彈簧預緊力時:
1)定子與轉子的偏心距保持zui大值2)泵的Q隨排出p增加而稍有降低,如特性曲線中AB段所示當排壓大于PB時, Fx增大使定子向減小e的向移動,泵的Q即隨排壓增加而迅速降低。當升到Pc時,e減小,Qt=漏泄量,則Q=0,有Pmax。
調節螺釘6和3,增大彈簧預緊力,PB, Pc 增大,特性曲線BC段右移。彈簧剛度越小,則BC段越陡, Pc 與PB, 越接近。螺釘3可變泵的zui大e,而改變Qmax,AB段就上下平移。內反饋限壓式變量泵只能單向變量。
