spiral high-speed rolling door

Hongfa spiral high-speed door with advanced technology 

For Industrial usage spiral high-speed door is a new advanced technologically alunimum high-speed door, which is designed and applied to many different working area and sites such public underground garage, supermarkets, hypermarkets, warehouses, loading docks, platforms, laboratories and pavilions and other quick passages.

1) Control System

Aluminum high speed door adopts special control system, adopts Servo special control box, single-phase 220 V or three-phase 380V with power 0.75-1.5-2.2KW, control box with main power control switch, emergency stop button, manual automatic conversion button , manually control the up and down buttons. Precise control of the opening height of the door.

2) Motor system

The motor drive system adopts a special servo motor system: single-phase 220V to three-phase 380V-power 0.75-1.5-2.2KW, well-known brand encoder; emergency manual opening mechanism;

1. Make the functions of safety guards (such as infrared rays) to the best and quickly rebound.
2. Strong overload capability. In some high-frequency occasions, the switch can work more than a thousand times a day, which can realize the automatic function conversion of the hand, and ensure the safe operation of the fast door. The control cabinet is set in the workshop, and the lift button must be provided on the outside of the fast door. Easy for outsiders to enter.

3) Security system

1. Infrared safety protection electric eye: there are pairs of radio eyes on both sides of the door frame. When there are obstacles under the fast door, the door body keeps open; when the door body descends, there is an object passing through, the door body will open to the open position, and the accessibility is below. The time delay then decreases. An external infrared device can be used to control the rapid rebound of the door. The bounce speed can be easily set by modifying the parameters. It is also possible to determine the function definition of the infrared device by modifying the parameters. For example, when the infrared is touched, whether it is a single-time bounce or a long-term non-moving function, the parameters can be determined by modifying the parameters.

2. Bottom safety protection side: When the door body is falling, because the object is in the blind zone of infrared safety protection, when the door body is pressed under the obstacle, the door body quickly rebounds upward, effectively protecting the object or pedestrian below, avoiding accident.

4) Wind resistance
Wind resistance is 32 m/s (national standard wind resistance level 12).

5) Sealing performance
Guide rail seal, door panel middle seal, door body top seal, door body bottom seal, multiple seals ensure airtightness and isolation inside and outside the door. 

The door is widely used in industrial plants in Europe and the United States, easy to use, easy to operate, reliable, and beautiful in appearance. The product is highly reliable, practical, easy to operate and low maintenance costs, and provides a full year warranty after installation. The control system uses the new cutting-edge DSP chip in the field of industrial control as the core, ensuring that there are more than 150,000 fault-free actions per year in the application.
