High speed spiral door is a new type of metal industrial door integrating heat preservation, energy saving, sealing, high efficiency, wind resistance and environmental protection. The new curved turbine and tension torsion balancing technology are suitable for industrial plants, logistics and warehousing.

(i) Daily inspection

Appearance check

l · Every day, before using the high speed spiral door, check the appearance of the door body. Check whether the door curtain is broken or scratched, and whether the sealing tape is peeling off or aging. If you find that the door curtain has a small damage, you can use special repair materials to repair; sealing rubber strips aging or falling off should be replaced in time to ensure the sealing performance of the door.

l · At the same time, check whether there are foreign objects on the surface of the track, such as dust, stones, etc. These foreign objects may affect the operation of the door and should be cleaned up in time.

Running check

l · Open and close the door body to check whether its running speed is normal. Under normal circumstances, the opening speed should be within the specified range, such as 0.8m/s - 1.5m/s. If the speed slows down significantly, it may be caused by motor failure, increased friction of the track, or damage to the transmission parts.

l · also check whether the door body has abnormal vibration and noise during operation. Slight vibration is normal, but if the vibration is too large or there is a harsh noise, it may be caused by the track installation is not solid, the door curtain and track friction or motor failure, etc., and you need to find out the cause and deal with it in time.

(ii) Regular maintenance

Cleaning Maintenance

l · Clean the rigid speed door regularly (once a month is recommended). Use a clean soft cloth and mild detergent to wipe the door curtains, avoid using detergents containing strong acids and alkalis, so as not to damage the surface of the door curtains.

l · For the inside of the track, you can use a brush to sweep, remove dust and debris, and then wipe with a clean, damp cloth. After cleaning, you can apply a small amount of lubricant on the surface of the track to reduce the friction when the door is running, but be careful not to apply too much so that the lubricant does not drip to the ground or other places.

Component Inspection and Tightening

l · Inspect the parts of the door body once a quarter. Check whether the screws and nuts are loose, especially the track fixing screws, motor mounting screws and other key parts. If looseness is found, use a spanner to tighten it in time.

l · At the same time, check whether the transmission parts, such as chains and belts, are worn. If they are badly worn, they should be replaced in time so as not to affect the normal operation of the door body. Check the running condition of the motor, including the temperature and sound of the motor. If the temperature of the motor is too high or the sound is abnormal, it may be the internal failure of the motor, which needs to be repaired by professionals.

(iii) Troubleshooting

common faults and treatment

l · door can not be opened or closed: first check whether the power supply is normal, including whether the plug is loose, whether the fuse is blown. If the power supply is normal, it may be a control system failure or motor failure. You can check the fault indicator of the control system and troubleshoot according to the instructions. If it is a motor failure, you may need to replace the motor or some parts of the motor.

l · Door jamming during operation: jamming may be caused by foreign objects in the track, friction between the door curtain and the track, or damage to transmission parts. Firstly, clean up the foreign objects in the track, check whether the door curtain interferes with the track, if there is any interference, you can adjust the position of the door curtain or the flatness of the track. If the problem still exists, check the transmission parts, such as whether the chain is loose, whether the belt is worn, etc., according to the situation for repair or replacement.

l · Decreased sealing performance: If you find that the sealing performance of the door has decreased, check whether the sealing rubber strip is damaged or aging. If it is a problem with the sealing tape, replace the tape in time. At the same time, check the fit of the door with the wall and floor, if there is a gap, you can use sealant to fill.

Professional Repair

l · For some complicated faults, such as damage to the circuit board of the control system and internal faults of the motor, it is best to have them repaired by professional repairers. Because these parts involve electrical knowledge and professional repair tools, non-professionals may lead to more serious problems. In the repair process, choose a regular repair manufacturer or after-sales service centre to ensure the use of original parts to ensure the quality of repair.

High speed spiral door service life of up to ten years, thanks to the high quality of the fast door itself, but also can not be separated from the use of the process of maintenance.
