Analysis of the working principle of the Xilang fast door
The Xilang fast door consists of a door frame system, a curtain system, a drive motor, a control system, and a control system.
Frame system: The main material is made of carbon steel or aluminum alloy.
Curtain system: mainly composed of PVC woven or aluminum alloy profiles.
Drive motor system: mainly composed of brake pads, motors, reducers.
Control system: using a sophisticated microcomputer controller,
Curtain thickness : 0.8mm-2.0mm . The 2.0mm thick door will change the structure of the entire product.
Safety system: mainly infrared electric eye switch, safe air pressure transmission American ATM company imported CPU , LCD man-machine interface display operating status and fault code, easy to use and maintain, with automatic closing 1-40 seconds adjustable;
Sensors (some companies with high mechanical precision and high stability control systems use safety contact belts) or light curtain systems; light curtain systems should be the highest level of safety protection .
Lifting speed: 0.8m/s-1.5m/s , generally from bottom to top in about 2 seconds (speed is 20 times that of electric shutters ), vehicles, pedestrians do not have to wait, do not constitute obstacles, higher speed is, foreign Ai The fast doors of companies such as Fulai, Bade, Hörmann, and Oponi can be controlled to 2.5 m / s or more.
 Door cloth material: Generally, PVC or PVDF film is used as the curtain cloth , especially the PVDF film material has better anti-aging performance, is not easy to fade and has self-cleaning function, and is very suitable for making a quick roll door.  　　
The colors are orange, yellow, blue, silver, transparent grid, black, etc. Orange is preferred because the orange is very eye-catching, stimulating the insect's perception and has a certain insect-proof function.
There are many ways to produce the door trigger signal in Germany or France : manual button, radar sensor, infrared photoelectric sensor, geomagnetic induction, remote control, etc.
