產品詳情
威格士4535V-42A35/45A35/50A35/60A35-1AA-22R葉片泵，泵中兩吸油區和兩壓油區各自對稱，使作用在轉子.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，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-轉時，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的圓環的體積。因為是雙作用泵，所以雙作用葉片泵的排量為葉片體積對排量無影響。因為在壓油腔，葉片縮回排出的液體體積補償了葉片在壓油腔所占的體積。葉片體積對排量無影響。因為在壓油腔，葉片縮回排出的液體體積補償了葉片在壓油腔所占的體積。連成一體，形成了一個組合的密封工作腔。隨著轉子的勻速轉動，位于大、小半徑圓弧處的葉片均在圓弧上滑動，因此組合密封工作腔的容積變化率是均勻的。實際上，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，葉片底槽在吸油區時，消耗壓力油,但在壓油區時，壓力油又被壓出，同樣會造成了流量脈動。由理論分析和實驗表明，雙作用葉片泵的脈動率在葉片數為4的整***且大于8時最小，故雙作用葉片泵的葉片數通常取為12或16。
