How to install the door closer

Use requirements and selection of door closers

Door closer products must meet the national standard GB2698-2005. Door closers used for fire doors should also comply with the requirements of GA93-1995Test for door closers for fire doors”.

The factors that should be considered when choosing a door closer are: the width of the door, the frequency of opening the door, and the requirements and environment of use. The width of the door is the most important factor in choosing the door closer model. Common doors include fire doors, wooden doors, aluminum alloy doors, glass doors, and steel doors. Usually the weight of the door is small, choose the model with less power, and vice versa. The frequency of door opening is closely related to the quality of the product. For frequent use, the sealing performance and long life of the product should be required.

1) Is there an automatic door stop function after opening the door;

2) Damping buffer function-the damping buffer is generated after the door is quickly opened to a certain position, and the damping buffer strength and range can be adjusted according to the use requirements; this function is used to prevent the door or lock from colliding with the wall surface or emergency escape when the door is quickly opened with force To prevent people from losing weight when opening the door quickly and leaning forward.

3) Delayed slow door closingThe door will be closed slowly and uniformly from the maximum position of the door opening, and can be adjusted steplessly according to the requirements. It is suitable for use in places with frequent access and many people, especially hospitals, with doors and passages for the elderly, children, and the disabled.

4) The closing force can be adjusted-it can be used on doors with different door weights and wide door widths, as well as places with high closing resistance due to environmental reasons. Random stepless adjustment can obtain a satisfactory closing force, especially in places such as coastal cities, vehicles and ships that are affected by wind and the closing resistance (the force of the door) often changes.

5) Temporary closing performance of damping reset function (vertical door closer)-when opening any angle, closing the governor valve should be able to temporarily suspend the damping reset function.

6) Safe and fast super-damping closing performance (vertical door closer)-when an external force is applied suddenly during closing at any angle, it should be able to close safely and quickly.

7) Operating environment: Fire and fire protection requirements and anti-freezing requirements for locations under minus 35° in winter.

Usually the choice of door closers can be based on the manufacturer’s product specifications, according to different strength or adjustable strength to match the size and weight of different doors.
