Zhongshan Huangpu inorganic dust cloth induction fast shutter doors rapid door industry quality products from the door frame systems, curtain system, drive motor, control system, control system. Frame System: The main material is carbon steel plate or stainless steel. Curtain system: the PVC fabric or composed of aluminum profiles. Drive motor system: the brakes, motors, gear components. Control Systems: The most commonly used is the complete set by the PLC / converter / encoder or IPM module comes with integrated circuit board, mostly domestic door industry enterprise control system is adopted PLC / converter / encoder based. Security system: electric eye infrared switches, safety pressure sensor (high part of the mechanical stability and high precision control systems businesses use safety contact strip) or light curtain system; curtain system should be the highest level of security of lifting speed: 0.8. m / s-1.5m / s, from bottom to top is generally about 2 seconds (20 times the speed of electric roller shutter), vehicles, pedestrians do not need to wait, do not constitute an obstacle, faster is open trigger a variety of : manual button, radar sensors, infrared photoelectric sensors, magnetic sensors, remote control and so on. Door fabric material: PVC or PVDF membranes generally as a cord, particularly PVDF membranes aging better performance, easy to fade and self-cleaning function, do a quick roll door is very suitable. Origin in Germany or made in France is preferred. Thickness of 0.8mm-2.0mm. 2.0mm thick door leaf, the product structure will change. Colors are orange, yellow, blue, silver, transparent mesh, black, etc., in orange is preferred, because the orange is very striking, stimulate sensory insect pest control has a certain function. Motor: rapid roll doors are used in brake geared motors, brake fast and low noise requirements. The general market sell brake motor brake or braking effect is not good either noisy, are not suitable for fast shutter. Ratio 1: 10-1: 15 is appropriate. This is a new kind of control, when you run the stop is not required by the brake to brake, noise and further down at the end.
