What are the common faults of electric sliding doors

Overview of electric sliding doors

The electric sliding door is mainly composed of motors, controllers, guide rails, pulleys, door bodies, etc., its basic working principle is to drive the door body to slide on the guide rail through the motor to realize the opening and closing of the door, the electric sliding door has the characteristics of automatic, convenient and safe, and is widely used in various occasions.

Analysis of common failures

1. The door cannot be opened or closed

Cause of failure:

(1) Power supply problem: The motor of the electric sliding door needs power supply, if there is a problem with the power supply, such as power failure, voltage instability, etc., it will cause the door to fail to work normally.

(2) Controller failure: The controller is the "brain" of the electric sliding door, if the controller fails, it will cause the door to fail to receive instructions or receive instructions by mistake.

(3) Blockage of the guide rail: If there is a foreign object in the guide rail, it will cause the door to fail to slide normally.

Solution:

(1) Check the power supply: make sure the power supply is normal and check whether the voltage is stable.

(2) Check the controller: check whether the controller is damaged, and replace it in time if it is damaged.

(3) Clean the guide rail: clean the foreign matter in the guide rail to ensure the normal sliding of the door body.

2. The door is not running smoothly

Cause of failure:

(1) Pulley wear: The pulley of the electric sliding door will wear out after long-term use, resulting in unstable operation of the door.

(2) Deformation of the guide rail: If the guide rail is hit by external force or deformed due to long-term use, it will also affect the smooth operation of the door.

Solution:

(1) Replace the pulley: If the pulley is seriously worn, the pulley needs to be replaced in time.

(2) Adjust or replace the guide rail: If the guide rail is deformed, the guide rail needs to be adjusted or replaced.

3. The door runs slowly

Cause of failure:

(1) Motor aging: The motor of the electric sliding door will age after a long time of use, resulting in the slow running speed of the door.

(2) Relaxation of the transmission belt: If the transmission belt is relaxed, it will cause the torque transmitted by the motor to decrease, which will affect the running speed of the door.

Solution:

(1) Replace the motor: If the motor is seriously aged, the motor needs to be replaced in time.

(2) Adjust the transmission belt: If the transmission belt is relaxed, the tightness of the transmission belt needs to be adjusted.

Preventive measures and routine maintenance

1. Check the power supply regularly: ensure that the power supply is normal and the voltage is stable.

2. Check the controller regularly: check whether the controller is damaged, and replace it in time if it is damaged.

3. Clean the guide rail and pulley: regularly clean the foreign matter in the guide rail, check the wear of the pulley, and replace the pulley with serious wear in time.

4. Regularly inspect the motor and transmission belt: check whether the motor is aging, whether the transmission belt is relaxed, and replace or adjust it in time if there is a problem.

5. Regularly check the access control system: ensure the normal operation of the access control system and prevent interference from external factors.

6. Waterproof and moisture-proof: The electric sliding door system should be kept away from the humid environment and avoid being soaked in water for a long time.

7. Gentle operation: avoid violently hitting the door body, so as not to cause damage to the door body or deformation of the guide rail.

As a modern automatic door system, the electric sliding door is convenient, fast, safe and reliable, with the growth of use time, the electric sliding door will also have some common faults, this article introduces the common faults and causes of the electric sliding door, and proposes the corresponding solutions, and also introduces preventive measures and daily maintenance methods to help users better maintain and use the electric sliding door, through the correct use and maintenance, the service life of the electric sliding door can be prolonged, and the use effect can be improved.
