油研介绍液压齿轮油泵的维修
1.壳体修理,壳体裂纹可用铸508镍铜焊条焊补。焊缝须紧密而元气孔,与泵盖结合面平面度误差不大于0.05毫米。
2.磨损修理,主动轴衬套孔磨损后,可用铰削方法消除磨损痕迹,然后配用加大至相应尺寸的衬套。从动轴孔磨损也以铰削法消除磨损痕迹,然后按铰削后孔的实际尺寸配制从动轴。
3.泵盖的修理,工作平面的修理:若泵盖工作平面磨损较小,可用手工研磨法消除磨损痕迹,即在平台或厚玻璃板上放少许气门砂,然后将泵盖放在上面进行研磨,直到磨损痕迹消除,工作表面平整为止。当泵盖工作平面磨损深度超过0.1毫米时,应采取先车削后研磨的办法修复。
4.修复齿轮泵主动轴与衬套磨损后,其配合间隙增大,必将影响泵油量。遇此,可采用修主动轴或衬套的方法恢复其正常的配合间隙。若主动轴磨损轻微,只需压出旧衬套后换上标准尺寸的衬套,配合间隙便可恢复到允许范围。若主动轴与衬套磨损严重且配合间隙严重超标时,不仅要更换衬套,而且主动轴也应用镀铬或振动堆焊法将其直径加大,然后再磨削到标准尺寸,恢复与衬套的配合要求。
5.泵壳内腔的修理,泵壳内腔磨损后,一般采取内腔镶套法修复,即将内腔搪大后镶配铸铁或钢衬套。镶套后,将内腔搪5、阀座的修理:限压阀有球形阀和柱塞式阀两种。球形阀座磨损后,可将一钢球放在阀座上,然后用金属棒轻轻敲击钢球,直到球阀与阀座密合为止。如阀座磨损严重,可先铰削除去磨痕,再用上法使之密合。柱塞式阀座磨损后,可放入少许气门砂进行研磨,直到密合为止。
