Spiral fast door05
Spiral hard fast door product hard fast door is also known as aluminum alloy fast door, referred to as hard shutter for short. It is a new type of metal fast door with anti-theft and high-temperature partition. It has reliability, practicability and easy operation. The door body lifting mechanism adopts aluminum alloy guided load-bearing track to ensure that the door curtain has no dry sound during high-speed operation and there is no friction between the door curtain and the track. According to the standard, the suction turbine can be divided into straight, elliptical and curved suction turbine structures, which can be divided into 90 degrees.
Product Performance
Operating speed: 0.5-0.8m/s Air tightness: 0.62M 3/ （m 2· h) , national standard grade 8 Water tightness: ≥ 700pa, national standard level 6 Wind resistance: National Standard Level 3 (relative deflection under 0.5kp wind pressure ＜ L / 180) Opening speed: the opening speed is 0.8m/s ~ 2m / S (related to the size of the door), adjustable Mean time between failures: 150000 times / year
Control System And Motor
The electric control box of fast door has stable performance, frequency conversion control and screen display, which is convenient for monitoring and fault checking. The customized servo motor can operate reliably in these two dangerous areas in both gas and dust environments.
Double Helix Structure
The aluminum alloy fast door adopts double spiral turbine structure. The guide rail is conducive to the acceleration of the door body, making the door body more stable at high speed, reducing the generation of noise and improving the safety index. At present, the single turbine structure used in the market is prone to cracks in the environment with large temperature difference, and safety accidents occur in serious cases.
Door Panel Structure
The aluminum alloy quick door panel is made of double-layer stretched aluminum plate, with fine pressed stripes on the surface, anodized and organic coloring treatment, and polyurethane foam filling in the middle. The middle internal bridge breaking design can improve the thermal insulation effect, prevent the loss of indoor and outdoor temperature, and save energy efficiently. The door panel surface is treated with 5 layers of organic coloring, which greatly improves the corrosion resistance.
Safety Device
The fast door is equipped with infrared radiation / safety light curtain and safety bottom edge. Infrared radiation / safety light curtain is 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 when the door body descends, the door will open to the open position, and the descent will be delayed when there are no obstacles below.
Opening Mode
Geomagnetic induction mode, radar induction mode or remote control mode.
