Fast rolling shutter doors have become a must-have equipment for more and more industrial enterprises. They play an important role in keeping the workshop clean, heat insulation, sound insulation, energy saving and emission reduction. The following SERANG technical engineers will introduce the products of fast rolling shutter doors Technical parameters and working principle:

The fast rolling door is composed of a door frame system, a door curtain system, a driving motor, a control system, and a safety protection system. Frame system: The main material is cold-rolled steel plate, stainless steel or aluminum alloy. Door curtain system: mainly composed of PVC curtain cloth or aluminum alloy profiles. Drive motor system: It is mainly composed of brake pads, motor and reducer. Control system: The most commonly used is the integrated circuit board with PLC/frequency converter/encoder set or its own IPM module. Most of the domestic door enterprises are mainly based on PLC/frequency converter/encoder. Door cloth material: PVC or PVDF film is generally used as the curtain, especially PVDF film has better anti-aging performance, is not easy to fade and has self-cleaning function, which is very suitable for fast rolling doors. The place of origin is German or French. Thickness 0.8mm-2.0mm. A 2.0mm thick door will change the entire product structure. Colors are orange, yellow, blue, silver, transparent mesh, black, etc., with orange as the first choice.

Safety system: mainly infrared electric eye switch, safety air pressure sensor (some enterprises with high mechanical precision and high stability of control system use safety contact belt) or light curtain system; light curtain system should be the highest level of safety protection. Lifting speed: 0.8m/s-1.5m/s, from the bottom to the top is generally about 2 seconds (the speed is 20 times that of the electric rolling shutter), vehicles and pedestrians do not need to wait, do not constitute obstacles, there are many ways to trigger the door: Manual button, radar sensor, infrared photoelectric sensor, geomagnetic sensor, remote control, etc.
