How to repair electric rolling door

As a common device in commercial and industrial environments, the normal operation of electric rolling shutters is essential to ensure safety and convenience. However, over time, electric rolling shutters may have various faults. This article will introduce the steps and precautions for electric rolling shutter repairs in detail to help readers solve common problems and ensure the normal operation of rolling shutters.

1. Preparation before electric rolling shutter repair

Before repairing electric rolling shutters, the following preparations need to be made:

1. Safety check: Make sure the rolling shutter is closed and disconnect the power supply to avoid electric shock accidents during repair.

2. Tool preparation: Prepare the required repair tools, such as screwdrivers, wrenches, pliers, wire cutters, etc.

3. Spare parts preparation: Prepare the corresponding spare parts in advance according to possible faults, such as motors, controllers, sensors, etc.

2. Common faults and repair methods of electric rolling shutters

1. The rolling shutter cannot start

If the rolling shutter cannot start, first check whether the power supply is normal, and then check whether the motor, controller, sensor and other components are damaged. If any parts are damaged, they should be replaced in time. If the power supply and components are normal, it may be that the circuit connection is poor. Check the circuit connection to ensure that the line is unobstructed.

2. The rolling door runs slowly

If the rolling door runs slowly, it may be a motor failure or insufficient voltage. First check whether the motor is normal. If there is any abnormality, replace the motor. If the motor is normal, check whether the power supply voltage is stable. If the voltage is insufficient, adjust the power supply voltage.

3. The rolling door stops automatically

If the rolling door stops automatically during operation, it may be a controller or sensor failure. First check whether the controller is normal. If there is any abnormality, replace the controller. If the controller is normal, check whether the sensor is damaged or improperly adjusted. If there is a problem, replace or adjust the sensor in time.

4. The rolling door is too noisy

If the rolling door is too noisy, it may be that the track is uneven or the pulley is worn. First check whether the track is flat. If there is any unevenness, adjust the track in time. If the track is normal, check whether the pulley is severely worn. If it is severely worn, replace the pulley in time.

3. Precautions for electric rolling door maintenance

1. Safety first: When repairing electric rolling doors, be sure to ensure safety. Safety measures such as disconnecting the power supply and wearing protective equipment are essential.
2. Accurate diagnosis: During the maintenance process, accurately determine the cause of the fault and avoid blindly replacing parts, which will cause unnecessary waste.
3. Use appropriate tools: Using appropriate maintenance tools can improve maintenance efficiency and avoid damage to equipment.
4. Follow the operating steps: Follow the correct maintenance steps to avoid secondary damage to the equipment.
5. Regular maintenance: In order to extend the service life of the electric rolling door, it is recommended to perform regular maintenance, such as cleaning the track and checking the parts.

Through the introduction of this article, I believe that readers have a deeper understanding of the maintenance methods of electric rolling doors. In actual operation, be sure to follow safety regulations, accurately diagnose the cause of the fault, and use appropriate tools and spare parts for maintenance. At the same time, regular maintenance is also the key to ensuring the normal operation of electric rolling doors. I hope this article can help readers in the maintenance process of electric rolling doors.
