KRACHT齒輪泵KF200RF7/74 的困油現(xiàn)象
閱讀:738 發(fā)布時(shí)間:2022-6-15KRACHT齒輪泵KF200RF7/74 的困油現(xiàn)象的解決方法:
(1)修正齒形
使封閉空間的容積變化減到小,該法應(yīng)用較小。
(2)泄壓孔
從動齒輪的齒頂?shù)烬X根鉆徑向通孔,再從動齒輪軸上銑出兩條溝槽(加工復(fù)雜)
(3)泄壓槽(卸荷槽)
在泵兩側(cè)蓋的內(nèi)側(cè),沿輪齒節(jié)圓的公切線方向,開出四個(gè)長方形凹槽(在每個(gè)側(cè)蓋的進(jìn)排油方向各開一個(gè))。凹槽的距離,必須大于一個(gè)輪齒齒間的厚度,以免使吸排腔直接溝通。
