• For a safe elevator, the user first feels the elevator door operation and the overall operation of the elevator. The high-quality door operation can obviously tell the elevator user that our elevator is safe, so the quality of the elevator door operation can fully reflect the Elevator Manufacturers . The technical strength and technical level of installation and maintenance, improving door running quality and removing door running noise are important tasks in installation and maintenance work. Here is a description of the causes and solutions of the elevator door running noise.

  1. When the hall door is running, the jitter or even the door difference is a few millimeters.
     the reason:
     1 The upper sill rail is covered with a block of sputum formed by dust;
     2 There are foreign objects in the ground tank.

  Solution: Polish the door guide with fine sandpaper to remove dirt and scrub with kerosene cloth to make the door guide clean and smooth. Remove foreign objects from the sill.

  2. The sound of "When" is issued when the hall door is opened.
     the reason:

     2 The gap between the hook lock and the lockbox is too small;
     3 The gap between the car door opener and the hook lock wheel is too large;
     4 The door opener starts to open too fast.

  Solution: adjust the level of the hook lock and the hook lock spring, adjust the gap between the hook lock and the lockbox, adjust the gap between the door opener and the hook lock wheel to 4~6mm, reduce the start door opening speed, and make the door opener Accelerate the operation by fully opening the hook lock.

  3. When the hall door is about to close, it will sound a "when" crash.
     the reason:

  Solution: Adjust the gap between the door opener and the hook lock wheel, and adjust the distance between the hook lock wheels so that the door opener can completely contain the hook lock wheel. Adjust the closing speed or torque at the end of the door.

  4, when the door is closed, the sound of "Zhi" is generated.

  the reason:
