Industrial sectional doors are suitable for various building exteriors and interiors. A complete operating system is formed through torsion spring tension balance, pulley slide sliding, and frequency conversion intelligent control system electric control. More than 6 lifting operation modes can also be customized according to the installation environment, 40mm thick high-density polyurethane foam door panels have both thermal insulation and impact resistance. The product has the characteristics of beautiful appearance, sturdy and durable, stable switching, low noise, sealing and heat preservation, safety and reliability, and saving plant space. It is widely used because of its high practicability and high-end appearance. So in daily use, how does the airbag of the industrial lift gate play the role of safety protection?
Inside and outside the industrial plant, when the industrial sectional door is normally closed and descended, people or obstacles encountered below the door block the airbag from descending, which produces a squeezing force on the airbag, making the airbag inside the airbag at this time. The air pressure has changed, and this air pressure change is quickly converted into an early warning signal and sent to the control system of the industrial sectional door. After the system receives the feedback from the airbag, the door body will immediately stop and continue to descend, and at the same time, the door will open upward in the opposite direction. It stops when it reaches the door opening position.
Through the above working process and control principle, it is not difficult to see that the function of the airbag is to ensure the automatic and automatic safety protection of the industrial lift door body when it encounters resistance during the closing and descending process, and effectively avoid the door body during the descending process. , the safety of vehicles, goods, etc., and at the same time avoid the damage to the door body caused by the continued descending of the door body when it is blocked.
