I think everyone should know that the electric rolling shutter door often appears in some shops, garages and other places. This kind of door is based on the manual rolling shutter door, which makes it more convenient and looks more high-tech. in the process of using it, there will be some faults. What are the causes? Through the following contents Find out
1. When the rolling shutter door is opened and closed, it will shake and make a harsh sound. The main reason for this is that there are debris on the track of the rolling shutter door, which hinders the movement of the pulley.
2. The opening and closing speed of rolling shutter door is too slow, which often needs to wait for a long time. The reason is that the motor voltage is abnormal or the belt between the motor and the rolling shutter door is loose. Or the friction between the fixed door and the movable door and the floor.
3. There is a crash sound when the Jinan electric rolling shutter door closes inward. The reason is: the closing speed of electric rolling door is too fast, or the motor itself has fault.
4. The rolling shutter door cannot work normally and cannot be started. The reason is that the circuit in the motor may be aged and short circuit may occur. The belt between the roller shutter door and the motor may also fall off, unable to transmit power. Jinan remote control rolling shutter door told everyone that the rolling shutter door was stuck by debris, unable to lift. Then the control switch of the motor may have problems, and the signal can not be transmitted normally.
5. When there is no control, the rolling shutter door will open and close automatically, because the control sensor is faulty. Or the sensor is interfered by other objects and cannot receive commands normally.
The above are the five common faults of electric rolling shutter doors. When these faults occur, we should first check what causes them, so as to provide better solutions. After a long time of use, some parts may be aging. If we want to delay the aging time, we should pay attention to some daily maintenance and regular inspection, if we find any fault during the inspection Barrier, to solve immediately, I think you should have more understanding of its fault after watching the above content.
