威格士4535V-42A35/45A35/50A35/60A35-1AA-22R葉片泵,泵中兩吸油區(qū)和兩壓油區(qū)各自對(duì)稱,使作用在轉(zhuǎn)子.上的徑向液壓力互相平衡,所以這種泵又被稱為平衡式葉片泵或雙作用卸荷式葉片泵。這種泵的排量不可調(diào),因此它是定量泵。2.雙作用葉片泵排量和流量圖可知,泵軸轉(zhuǎn)-轉(zhuǎn)時(shí),從吸油窗口流向壓油窗口的液體體積為大半徑為r,小半徑為r,寬度為b的圓環(huán)的體積。因?yàn)槭请p作用泵,所以雙作用葉片泵的排量為葉片體積對(duì)排量無(wú)影響。因?yàn)樵趬河颓,葉片縮回排出的液體體積補(bǔ)償了葉片在壓油腔所占的體積。葉片體積對(duì)排量無(wú)影響。因?yàn)樵趬河颓,葉片縮回排出的液體體積補(bǔ)償了葉片在壓油腔所占的體積。連成一體,形成了一個(gè)組合的密封工作腔。隨著轉(zhuǎn)子的勻速轉(zhuǎn)動(dòng),位于大、小半徑圓弧處的葉片均在圓弧上滑動(dòng),因此組合密封工作腔的容積變化率是均勻的。實(shí)際上,由于存在制造工藝誤差,兩圓弧有不圓度,也不可能完全同心;其次,葉片有一定的厚度,根部又連通壓油腔,葉片底槽在吸油區(qū)時(shí),消耗壓力油,但在壓油區(qū)時(shí),壓力油又被壓出,同樣會(huì)造成了流量脈動(dòng)。由理論分析和實(shí)驗(yàn)表明,雙作用葉片泵的脈動(dòng)率在葉片數(shù)為4的整***且大于8時(shí)最小,故雙作用葉片泵的葉片數(shù)通常取為12或16。
