Door Curtain Parallel and double-layer stacking type, the distance between two door curtains is about 300-1200 mm. The composition of the curtain, the curtain imported from France is composed of double-sided industrial belt (high polymer fiber bi-axial warp knitted fabric and PVC coating compound) and ribs.
This combination can not only ensure the anti-wind strength requirement of the door curtain under the condition of strong wind, but also reduce the weight of the door curtain, thus easy to operate.
The principle of wind resistance is the wind from the door curtain to the ribs, and from the ribs to the building steel structure and the ground.
Power System:
power system by a group of Motor, reducer and brake system, will be used in Germany brand SEW special motor, the same domestic brand.
Control System:
control system by motor control system, motor overload protection system, all components in a control box.
Safety System, in the opening process or power failure, by the power system braking system to provide sufficient braking force to prevent any circumstances curtain of the self-sliding, the strength of the sling safety system for 5 times.
In the case of breakage of the lifting sling, the door body can be effectively prevented from falling by the automatic Hook anti-falling system.
Sealing system:
in order to effectively ensure the integrity of the sealing system, between the curtain and sliding door cylinder aluminum alloy plate seal.
Design conditions:
overall dimensions of the door: 10-40M net width, 10-30 M High Door
Wind equivalent: Standard Wind pressure 55kgm2;
Factor of safety 1.4, that is, maximum design wind pressure 77kgm2
Rise speed: 6-9 M Min, door curtain with anti-aging and wear-resistant performance, the overall sealing performance of the door, double curtain insulation (single layer thickness of 1 mm).
