Hard fast door

Door body mechanism: the door curtain is a split assembly structure: it is composed of bridge cutoff and thermal insulation aluminum alloy door panel, multi-layer sealant strip, sound attenuation bearing hinge, polyurethane guide wheel and other parts:

1. The standard thickness of aluminum alloy thermal insulation door panel is 40mm, the surface is anodized and organic coloring treatment, and the wind resistance can reach Grade 12. The middle is Owens Corning imported glass wool fire insulation, according to the international color card standard color; Available colors: aluminum alloy primary color, pearl white, Chinese red, etc;

2. The door panels are sealed with soft connection adhesive tape, and the folding life of the soft connection part is more than one million times;

3. The hinge bearing mode is designed so that the door curtain joint is not stressed and the door panels are not in contact with each other, and the flatness can be maintained after a long time;

4. When the door body is running, it slides in the aluminum alloy track through the polyurethane guide wheel.

Safety system: 1. Infrared safety protection electric eyes: opposite electric eyes are set on both sides of the door frame. When there are obstacles under the fast door, the door body remains open; When an object passes through the door body when it descends, the door will open to the open position, and the door will descend after a delay when there is no obstacle below. The external infrared device can be used to control the rapid rebound of the door. You can easily set the rebound speed by modifying the parameters. The function definition of the infrared device can also be determined by modifying the parameters. For example, when touching the infrared device, whether it bounces in a single action or makes the door immovable for a long time can be determined by modifying the parameters.

2. Bottom safety protection edge: when the door body is descending, because the object is in the blind area of infrared safety protection, when the door body is pressed against the obstacle below, the door body will bounce back at the most open door, effectively protecting the object or pedestrian below the household from accidents. Wind resistance

Wind resistance: 32 m/s (national standard wind resistance grade 12)

Transparent window: high-quality polycarbonate board. The design of double-layer structure not only ensures the thermal insulation effect inside and outside the door body, but also maintains good transparency and

The daylighting effect is clearly visible inside and outside, and the appearance shows the grade.

Sealing performance: guide rail sealing, middle sealing of door panel, top sealing of door body, bottom sealing of door body, multiple sealing to ensure air tightness and isolation effect inside and outside the door body.

Thermal insulation performance: for the installed closed door (4x3m), thermal insulation performance K ≤ 0.6W/(㎡• K)

Quick repair: In case of damage to the door panel, it is unnecessary to disassemble the whole door panel for repair. The hanging fixed aluminum alloy door panel can be disassembled one by one, which is simple and time-saving

Manual function: In case of power failure, the electric control is equipped with a reserve power supply to open the motor brake at any time, and the door can be lifted by the balance system, which can effectively solve the problem that the door cannot be opened due to power failure or fault.

Balance system: balance springs are equipped inside the door posts on both sides to keep a certain balance with the weight of the door panel, and reduce the load of the motor during operation, so that it can operate smoothly.

Overall exterior: Precisely formed turbine system, guide rail system and protective cover made of Baosteel galvanized sheet by laser cutting and CNC bending, which will not rust for a long time, and the exterior is beautiful, dust-proof and easy to clean

Transmission system: the integrated transmission system makes both sides of the door evenly stressed and the overall operation smooth.

Mechanism lifting: The turbine type aluminum alloy guide rail independently developed is used, which is in line with the guide rail system used for fast speed change. The door body is quickly inhaled during operation, effectively preventing vibration and noise.

Control box: thickened IP54 control box, meeting national electrical safety standards.

Door plate traction: It adopts high-quality wear-resistant and high-strength roller chain structure, and the door body is driven into the turbine mechanism with fast speed change through the synchronous chain.

Power supply requirements: 380V/14A/50Hz/.

Insulation protection: Ip54 can be waterproof and dustproof even in harsh environments.

Switching mode: standard one button with emergency stop switch; Manual opening mode after power failure.
