The fast door has a variety of safety maintenance system software, in which a key part is the fast door buffer device and its airbag.

1. Cache Device

The rollers of the fast door push the door frame to operate in the rails on both sides to keep the door frame open and close. If the limit switch device for operation is not working, the door frame will get rid of the original operation trajectory. Therefore, it is necessary to install cache equipment at the tail end of the rails on both sides.(Also called limit switch equipment), used to limit the door frame to get rid of the rail when the limit switch is not working, and also has the effect of pushing the door page when the store is closed.

2. airbag

There is a safety air charge under the bottom of the door frame. The airbag is divided into two types: cable TV type and wireless network type, which are connected to the pneumatic power switch. When the bottom of the door frame touches the roadblock during the whole process of sliding down, the airbag is reduced and the standard air pressure fluctuates, and then the pneumatic power switch is turned on. After the automatic control system receives the data signal from the pneumatic power switch, the door frame immediately terminates Operation or live in operation, which has the effect of safety maintenance.

It is expected that according to the detailed introduction of the cache equipment and basic information about the fast door and the airbag, it will help you to some extent.
