How to determine whether the rolling door needs repair

 

1. Appearance inspection

Door surface: Observe whether there are obvious dents, scratches, deformation or rust on the door surface of the rolling door. If these problems appear on the door surface, it may affect the appearance and performance of the door and require repair.

Guide rails: Check whether the guide rails are flat, vertical, bent, deformed or damaged. If there is a problem with the guide rails, it may cause the door to jam, tilt or fail to open and close properly during operation.

Curtain blades: Check whether the connection between the curtain blades is tight, loose, falling off or damaged. If there is a problem with the connection of the curtain blades, it may affect the sealing and safety of the door.

2. Operation inspection

Opening and closing speed: Pay attention to whether the opening and closing speed of the rolling door is normal. If the speed of the door is significantly slower or faster, it may be caused by motor failure, transmission system problems, or imbalance of door weight, and repair is required.

Operation stability: Observe whether the door is stable during opening and closing, and whether there is any shaking, jamming or abnormal noise. If the door is not running smoothly, it may be caused by uneven guide rails, worn transmission parts or motor failure, and needs to be repaired.

Limit function: Check whether the limit function of the rolling door is normal. When the door reaches the upper or lower limit, it should stop running automatically. If the limit function fails, it may cause the door to over-run and damage the door body or motor.

3. Safety Check

Safety device: Check whether the safety device of the rolling door is working properly, such as the rebound device when encountering obstacles, the safety bottom edge, etc. When the door encounters an obstacle during operation, the safety device should be able to start in time to stop the door from running or rebound. If the safety device fails, it may cause harm to people and objects and needs to be repaired.

Locks: Check whether the door locks are secure and reliable and whether they can lock the door properly. If there is a problem with the locks, it may affect the security of the door and require repair.

4. Electrical inspection

Motor: Listen to see if the motor has any unusual noise, heat or vibration during operation. If the motor has these problems, it may be caused by motor failure, electrical circuit problems or excessive load, and needs to be repaired.

Control system: Check whether the control system of the rolling door is working properly, such as whether the remote control, buttons and other operating devices are sensitive and reliable. If there is a problem with the control system, it may cause the door to not open and close normally and require repair.

By checking the appearance, operation, safety and electrical aspects of the rolling door, you can determine whether the door needs repair. If any problems are found, you should contact professional maintenance personnel for inspection and maintenance in time to ensure the normal use and safety of the rolling door.
