一台E512联合收割机,方向机上盖联轴节处出现渗油现象,擦干净后又渗出油迹,每工作一个班次能接液压油300～350克。由此确定O型密封胶圈磨损。卸下方向机,打开上盖,小心取出O型胶圈,发现与联轴节接合处有磨损现象。由于当时缺少此类型的O型密封圈,其它规格的装上,不是紧就是松。最后只好采用O型圈加垫法,解决了问题。即用原O型密封圈,根据磨损程度选用一张厚度相仿的账页纸,根据胶圈环槽的宽度和周长,剪一纸条压入槽底,然后小心地将O型密封圈压入槽内。重新装复方向机,不再渗漏。我们曾用这一简单修理方法解
A E512 combine harvester, the direction of machine cover joints appear bleed oil phenomenon, wipe clean and oozing oil, each shift can take a shift of hydraulic oil 300 to 350 grams. This determines the O-ring wear. Remove the direction machine, open the cover, carefully remove the o-ring and found that there are joints with the joint wear phenomenon. Due to the lack of this type of O-ring, the other specifications are not loose or loose. Finally had to use O-ring pad method to solve the problem. That is, using the original O-ring, according to the degree of wear selected a similar thickness of the absorbent paper sheet, according to the width and perimeter of the apron ring groove, cut a note into the groove, and then carefully O-ring pressure Into the tank. Reinstall the direction machine, no leakage. We used this simple solution
