Elevator door system failures account for a large proportion of the total failure rate of elevators. Among them, the car door mechanism is the most frequently operated system in elevator work, and it is directly related to the safe and reliable operation of the elevator. The failure rate of the car door system accounts for a considerable proportion of the failure rate of the door system. The main reason is mostly because the installation process of the car door system fails to meet the design requirements. The following Observation Elevators Manufacturer will teach you how to properly adjust the elevator car door.

1. The installation of the door opener, car door, safety touch panel and door knife has been completed by the installation team during maintenance and will not be described further.
2. The adjustment of the car door is the premise of the door system adjustment. Only after the car door is adjusted, does the colonel's hall door be checked (I am).
3. First use a hair dryer to remove dust from the car door, and then sand the car door track with sandpaper of 300 # or more to ensure the car door to operate flexibly.
4. To adjust the car door, you must:

① The distance between the door panel and the sill is 4mm, and the distance between the car door and the front wall of the car is 4-6mm (not too small);
② The two car doors must be on the same plane. The inspection method is to use a steel ruler to lean the upper and lower ends of the two door panels to see if it is flat;
③ The front and side of the door panel must be vertical to ensure that the closed seam is neatly closed, and at the same time, it is aligned with the front wall of the car. After the car door is adjusted, the door can be opened and closed manually, and the entire opening and closing process should be easy and stable.

5. Adjust the touch panel and light curtain.
When the touch panel is extended, the protrusion amount of the touch panel is preferably from 30 to 50 mm. When used, the two touch panels are extended by the same amount. The light curtain should be flush, and there should be no abnormal trigger during the fast opening and closing of the door. Especially for the rear light curtain, keep it clean.

6. Adjust the door opener:
① Make sure that the distance between the door knife and the hall sill is 7mm, and that the direction is vertical;
② Make sure that the distance between the blade of the door knife and the decoupling roller of the hall door lock is about 7mm; run the elevator throughout the inspection to observe, take this clearance of most hall doors, and move the car to the right and left in a small amount Door assembly.
③ The two sides of the door knife blade, that is, the side of the push roller must be vertical;
④ Check that when the car door drives the hall door, the blade should not make any abnormal noise.

7. Adjust the speed of opening and closing the door:
It should be adjusted when the car door drives the hall door, the speed is controlled at about 0.70m / s, and the door opening speed can be appropriately faster. The acceleration and deceleration of door opening and closing are adjusted according to different elevators. It is mainly the acceleration and deceleration time of the curve inflection point; it is required to adjust the angle of the inflection point into a curve after adjustment, not a polyline. The acceleration and deceleration of the opening and closing of the door must be soft, and there must be no impact during opening and closing.

China Elevator Lifts Factory,Freight Elevators Manufacturers also reminded the maintenance staff to place and repair the warning signs every time they repair, to ensure their own safety and the safety of others.
