& Rapid door Rapid rolling door is an automatic control equipment, consisting of door frame, C door curtain, drive motor and control system. Lifting speed: ././, from bottom to top generally takes about seconds (the speed is twice that of electric rolling shutters). Vehicles and pedestrians do not need to wait and do not constitute an obstacle. There are many ways to trigger signals for opening the door: manual button, radar induction, infrared photoelectric induction, geomagnetic induction, remote control, etc.
Door cloth material: C is generally used as the curtain cloth. Especially the membrane material has better anti-aging properties, is not easy to fade and has a self-cleaning function. It is very suitable for fast rolling doors. The origin is preferably German or French. thickness... Colors include orange, yellow, blue, silver, transparent mesh, black, etc. Orange is the first choice because orange is very eye-catching, has a warning effect, and has a certain insect-proof function.
Drive motor: Fast rolling doors use brake reduction motors, which require fast braking and low noise. Generally, the braking motors sold on the market either have poor braking effect or have loud braking noise, and are not suitable for use in fast rolling doors. Speed ratio: more appropriate.
Working process: The door opening sensor provides a trigger signal to the control system. The control system sends instructions to the frequency converter according to the current position of the fast rolling door. It starts the drive motor to make the door curtain rise quickly. After vehicles and pedestrians pass through, the door curtain automatically drops and the passage is closed. , until the next door opening signal is turned on again. As the name suggests, the fast rolling door lifts and lowers very quickly and cannot be started and stopped directly like the steel rolling door. Generally, a frequency converter is required to control the speed of the motor. The faster it rises, the better. When it is almost in place (around c), there needs to be a deceleration and buffering stop process to prevent hitting the track, preventing people from being pinched, and reducing noise. This is also a standard for measuring the performance of fast rolling doors.
