莱钢型钢厂大H型钢生产线矫直辊装配液压螺母是矫直机进行工艺装配的专用设备,长期存在漏油现象。经分析,其结构设计不合理是造成泄露的原因。将O型圈由原来嵌装在活塞环的环形槽内,改为嵌装在螺母的环形槽内;对活塞环的结构、材料和加工工艺进行一些改造;并针对性的制定合理的装配要点。该项改造实施后,矫直辊装配液压螺母3年多未出现泄露。
Ligang steel mills large H-beam production line straightening roller assembly hydraulic nut straightening machine for process assembly of special equipment, the long-term existence of oil spills. After analysis, its structural design is unreasonable is the cause of leakage. The O-ring is embedded in the annular groove of the piston ring instead of the annular groove of the nut, the structure, the material and the processing technology of the piston ring are modified; the rational assembling points . After the implementation of the transformation, the straightening roller assembly hydraulic nut more than three years did not leak.
