在施工现场作业的工程机械,其液压缸活塞杆表面被划伤或击伤现象时有发生。液压缸活塞杆上的划痕应及时修复,否则将造成密封失效,导致液压缸漏油。对不严重划痕的处理,通常采用油石打磨方法清除毛刺。对于比较严重的划痕,通常采用拆下液压缸活塞杆进行刷镀处理。而刷镀处理修复周期长、成本高。为此我总结出在施工现场快速修复划痕的2种方法。 Construction machinery operating on the construction site, the hydraulic cylinder piston rod surface scratches or injuries have occurred. Hydraulic cylinder piston rod scratches should be promptly repaired, otherwise it will result in seal failure, resulting in hydraulic cylinder leakage. Not serious scratches on the treatment, usually using the stone grinding method to remove burrs. For more serious scratches, usually remove the hydraulic cylinder piston rod brushing. The brush plating repair cycle length, high cost. To this end, I summarize 2 ways to quickly repair scratches at the construction site.
