The maintenance of high-speed rolling shutter doors has always been a problem frequently mentioned by enterprises. Some companies may wonder why some high-speed rolling shutter doors have a long service life, but some are very short for the same brand of high-speed rolling shutter doors. The most important thing is maintenance, so how to maintain the fast rolling door? The following summarizes the four-step maintenance method:

When the fast rolling shutter door has been used for a certain number of years, we should conduct a comprehensive inspection and maintenance of the product, and timely check to find possible potential safety hazards. Parts repair and replacement;

1. Power and brake system: When the brake system fails, it should be repaired and replaced in time; for example, the brake is not sensitive, the door body continues to slide after the brake, the sound is very loud when braking, and there will be a gap pause when the fast rolling door starts; When the above faults occur, if the maintenance and replacement are not carried out in time, if the contents of the warning are not carried out, the door may suddenly fall, the motor may be damaged or other parts may be damaged, and personal injury may be caused.

2. Fast door safety device: The fast door safety system is an installation protection device other than the brake system, and a pneumatic safety device is installed at 25CM below the left and right tracks of the door or at the bottom. In the process of closing the door, if there are vehicles and pedestrians passing by, the fast door will automatically stop and then run upwards until it is fully open. When the safety photoelectric and airbag are faulty, it should be repaired or replaced in time; if the door is not replaced in time, it is easy to cause pedestrians and vehicles to be injured due to the excessive speed during the downward running process.

3. Control switch system: The control switch system is composed of the output, closing, signal conversion, programming and other main components of the high-speed door. It is divided into integrated circuit board control chip and independent electrical components. Electronic components have high requirements on the use environment. In order to ensure fast, efficient and safe operation, product maintenance should be carried out frequently during daily use. When the control system fails, it should be replaced and repaired in time;

4. Others: Such as steel structure, wind resistance device, sealing device, door body structure, interlocking device, emergency stop device, roller roller, limit device, switch device, etc. are inseparable systems. Maintenance and maintenance during normal operation is crucial.
