The composition and structure of industrial fast doors

The industrial fast door is a curtain structure composed of several cloth curtains subjected to high temperature. The main functions are heat preservation, moisture retention, dust prevention, insect prevention, sound insulation, etc., so that the workshop can maintain a constant temperature, constant humidity and clean working environment. Applicable to food, medicine, electronics, rubber, chemical industry, automobile, textile, logistics and other fields. The opening of industrial fast doors can be divided into button switches and automatic induction switches. The automatic induction switch provides a trigger signal to the control system by the door opening sensor. The control system sends instructions to the inverter according to the current position of the fast rolling door, and starts the drive motor to make the curtain rise rapidly. , Vehicles and pedestrians pass through the rear door curtain, which automatically descends and closes the passage until the next door opening signal opens again. As the name implies, the fast rolling door lifts very fast and cannot be started and stopped directly like a steel rolling gate. Generally, a frequency converter is needed to control the speed of the motor. The faster the ascent, the better. When it is in place (about 500px), there needs to be a deceleration buffer stop process to prevent hitting the track, prevent people from being trapped, and reduce noise. This is also a standard for measuring the performance of a fast rolling door.
