[Dongguan Dalang Huangjiang fast door supply] how to choose fast door, please call Haifeng
The fast door is provided by the door opening sensor, which is used to trigger the signal to the control system. The control system will send the command to the frequency converter according to the current position of the fast shutter door, start to drive the motor door curtain to rise rapidly, the vehicle and pedestrian will automatically lower the curtain through the rear door, close the channel, until the next door open signal is opened again. The fast rolling gate cannot be started and stopped directly like the rolling gate. Generally, frequency converter is needed to control the speed of motor. The faster the door rises, the better. After being put in place (about 20cm), deceleration buffer parking process is required to prevent collision with the track, prevent personnel from being caught and reduce noise. This is also a standard to measure the performance of fast rolling shutter door.
Quick door selection. Then, how to choose, how to distinguish good from bad? Next, Haifeng will answer for you:
The standard configuration of ordinary fast rolling shutter door is: door body, control box, motor, limiter, button switch, infrared anti reflection protection device, anti-collision column, warning light, etc.
1. Electric control box of fast rolling shutter door: main frequency conversion function. The most important parts are PLC and frequency converter. The connection of the photoelectric system also has a certain number of terminals.
2. Fast shutter motor: the main drive system drives the spindle to rotate, and drives the belt to rise and fall.
3. Intelligent encoder / mechanical limiter: it limits the door body and determines the operation range of the door body, i.e. the rising height and falling position of the door body during operation. The encoder is superior to mechanical limiter in performance and convenience, and has been widely used.
4. Vehicle detector: it is connected with ground induction coil to detect vehicle signal and make the door body rise and fall automatically.
5. Infrared anti shooting protection system: generally there are two specifications: single shot and anti shot. When the infrared ray is cut off, the door will automatically rebound and rise to prevent damage.
