2、Working principle of Explosion-Proof Automatic Fast Door

The principle of Explosion-Proof Automatic Fast Door is introduced as follows:

1. Winding opening and closing

The special motor drives the reel to rotate, and the soft PVC or polyester fiber door curtain is wound on the reel to realize opening; When the motor rotates reversely, the door curtain falls down and closes smoothly along the track by its own gravity and the retracting and retracting action of the reel. The vertical speed and stroke of the door curtain can be adjusted by controlling the forward and reverse rotation and rotation speed of the motor.

2. Door curtain winding

The door curtain is usually made of high-strength soft materials such as PVC or polyester fiber. The door curtain is wound or unfolded on the reel driven by a motor to realize the opening and closing of the door. Because the door curtain is soft, the winding process can be completed quickly, which improves the running speed of the door.

3. Sealing and dustproof

The edge of door curtain is usually designed with special sealing structure, such as brush seal, rubber strip seal, etc. When the door is closed, these sealing structures can be closely attached to the door frame, effectively preventing the exchange of dust, mosquitoes, cold and hot air, etc., playing a good sealing role and maintaining the stability of the indoor environment.

4. Induction opening

Equipped with a variety of sensing devices, such as infrared sensing, radar sensing, geomagnetic sensing, etc. When someone or an object approaches, the sensing device will send a signal to the control system, and the control system will drive the motor to open the door curtain after receiving the signal, so as to realize the automatic opening function and facilitate the rapid passage of people and goods.

5. Winding opening and closing

The special motor drives the reel to rotate, and the soft PVC or polyester fiber door curtain is wound on the reel to realize opening; When the motor rotates reversely, the door curtain falls down and closes smoothly along the track by its own gravity and the retracting and retracting action of the reel. The vertical speed and stroke of the door curtain can be adjusted by controlling the forward and reverse rotation and rotation speed of the motor.

3、Explosion-Proof Automatic Fast Door advantage

The advantages of Explosion-Proof Automatic Fast Door are as follows:

1. High speed operation

Fast opening speed, can quickly isolate the internal and external environment, improve the traffic efficiency of the place, and reduce air convection.

2. Wear resistance and flexibility

It is made of high-strength soft material, which is wear-resistant and tear-resistant, suitable for frequent opening and has long service life.

3. Thermal insulation

The used high-quality soft materials have certain thermal insulation performance, and with good sealing effect, it can reduce indoor and outdoor heat exchange, which is helpful to maintain indoor temperature stability and reduce energy consumption in places where temperature control is required, such as cold storage and food processing workshops.

4. Good seal

Elastic PVC base cloth is installed at the bottom, which can be closely attached to uneven ground, and cushioning material is filled inside to enhance wear resistance and durability. The two sides of the doorpost are equipped with brushes with high sealing performance, which can effectively prevent insects and moth, reduce noise, significantly improve sealing effect, and effectively block dust, mosquitoes, odor and convection of hot and cold air.

5. High speed operation

The imported motor with servo control system is adopted, which has slow opening speed, can be quickly opened and closed, and improves the passage efficiency. It is suitable for scenes with high requirements on logistics flow and frequent door opening and closing, such as logistics warehousing and workshops, which can effectively reduce the waiting time for cargo loading and unloading and improve the overall work efficiency.

4、Structural characteristics of Explosion-Proof Automatic Fast Door

The Explosion-Proof Automatic Fast Door has the following structure

1. Induction system

Equipped with infrared induction, radar induction, geomagnetic induction and other devices, real-time monitoring of the surrounding environment, automatically trigger the door curtain to open, improve traffic efficiency.

2. safety devices

It is equipped with infrared photoelectric induction protection and a safe bottom edge (rebound when touching the bottom) to prevent people from being caught and objects from being caught, so as to provide safety guarantee for people and goods to enter and leave.

3. Drive assembly

Special shutter motor is equipped with reel, and some parts are equipped with servo control system, which realizes high-speed winding and precise control of door curtain and ensures rapid opening and closing.

4. Track design

The nylon brushes are installed in the aluminum alloy tracks on both sides, which not only reduces the friction between the door curtain and the track, but also plays a role in sealing and dustproof, ensuring smooth operation.

5. Door curtain material
