我单位一台36t进口吊机的大臂液压伸缩活塞杆,因使用不当造成弯曲。由于未及时校正,造成活塞杆表面严重拉伤,铜套受损,油缸泄漏,大臂自动下落。 在压床上校正弯曲的活塞杆,易损伤表面,修复十分困难。我们用《设备管理与维修》杂志介绍的贝尔佐纳高分子修补材料,解决了这一难题。 方法是:在铣床上沿损伤表面铣出一个宽6mm、深2.5mm、长1.5m的槽,再按使用说明依次进行清洁、干燥、配料、施料、固化、 My unit 36t imported crane boom hydraulic telescopic piston rod, due to improper use caused by bending. Due to not promptly corrected, resulting in serious strain on the piston rod surface, damaged copper sleeve, cylinder leaks, the boom automatically drop. Correcting a bent piston rod on a press can easily damage the surface and repair is difficult. We solved this problem with Belzona polymer repair material, described in the article “Equipment Management and Repair.” The method is as follows: milling a groove 6mm wide, 2.5mm deep and 1.5m long along the damaged surface on the milling machine, followed by instructions for cleaning, drying, ingredients, materials, curing,
