Report on Repairing Office Chairs
Repairing office chairs requires targeted methods based on specific fault types. Common issues include structural cracking, hydraulic system failure, and component wear, which can be efficiently repaired using professional tools and suitable materials.
For structural cracking, it is essential to accurately locate the damage and control the repair temperature. In the case of Liaocheng Qianbaohang, the iron plate at the bottom of an office chair cracked, causing it to tilt. The sheet metal technician discovered that the cracking was closely related to the hydraulic column through analysis. Direct welding could damage the internal seals of the hydraulic column, so a process of immediately sprinkling water to cool after welding was adopted. A simple sprinkler made from a discarded beverage bottle was used to control the cooling rate, preventing secondary damage to the hydraulic system from high temperatures. This method not only repaired the iron plate structure but also preserved the function of the hydraulic column, making it suitable for repairing metal frame cracks.
Hydraulic system failure requires replacing suitable components and testing for safety. The executive chair in the general manager's office of a company in Guangzhou Tianhe could not adjust its height due to the failure of the internal pressure rod in the lifter. The repair team chose to replace it with a high-strength explosion-proof lifter. Such components need to pass pressure tests to verify their load-bearing capacity, ensuring they meet the frequent lifting requirements of office scenarios. After repair, multi-angle load-bearing tests should be conducted to avoid secondary failures caused by mismatched components.
For component wear faults, priority should be given to selecting quiet and durable replacement parts. In an open office area, 12 staff chairs had issues with worn wheel bearings and cracked wheels. The repair team opted to replace them entirely with quiet universal wheels. These wheels must meet three core indicators: the bearings should have a sealed design to reduce dust ingress, the wheel body should be made of polyurethane material to reduce friction noise, and the gap between the rotating shaft and the fixed frame should be controlled within 0.5mm to ensure smoothness. After replacement, mobility tests should be conducted in a simulated office environment to confirm there is no stuttering or abnormal noise.
The repair process should balance efficiency and office order. In the Guangzhou case, the repair team avoided peak office hours by working in batches, with each chair's repair time controlled within 20 minutes, ensuring no disruption to the company's normal operations throughout the process. For corporate users, it is recommended to choose a professional team that offers on-site services and requires the repair team to carry an inventory of commonly used components to reduce waiting times.
