The Characteristics of the Industrial Rolling Door and the Reasons for the Failure to Open the Door

Fast roller shutter doors refers to the door with a running speed of more than 0.6 meters per second. It is a barrier-free isolation door with fast lifting. The main function is heat preservation, moisture preservation, dust prevention, insect prevention, sound insulation and so on. To keep the workshop constant temperature, humidity and clean working environment. It is suitable for food, medicine, electronics, rubber, chemical, automobile, textile, logistics and other fields.

Ⅰ. Characteristics of fast roller shutter doors

1. The speed of the fast rolling shutter door is 20 times higher than that of the traditional door, realizing the high-speed opening and closing of 100 times per hour and a high degree of durability.  In addition, the opening height adjustment function can shorten the opening time, improve the efficiency of indoor air conditioning. To control exception object outside mixing in to a minimum. At the same time improving work efficiency.

2. Fast roller shutter doors can be opened quickly: stacking type opening and closing, opening speed 0.8-1.4m/s;  Closing speed 0.5-1.0m/s.

3. Fast roller shutter doors can preserve heat and save energy : the fast opening and closing function of the door improves the cold and warm insulation effect of summer and winter , reduces the loss of energy and saves energy.

4. The safety performance of fast industrial roll-up doors: the material of door frame and door box is 2.0-2.5mm thick high quality cold-rolled steel structure, high quality baking, painting process; 2.0-2.5mm thick stainless steel or 3.5mm high strength 6063 oxidation resistant industrial aluminum alloy column.

5. Seal isolation: the bottom of the fast industrial rolling door is equipped with elastic PVC cloth gas seal. The fast industrial rolling shutter door can be combined with all kinds of uneven ground accurately, which can reach ten thousand level standard. The door column seal uses a special double brush to make a better sealing performance.

6. Unique sealing system, efficient sealing method, maximum block movement of cold and hot wind, prevent dust, insects from entering, effectively isolate the spread of odor, noise.

7. Power system of fast industrial rolling door: We use special motor.

8. Control system of fast industrial rolling door: high-tech PLC and converter control.

At present, the demand for fast rolling shutter doors is increasing, and it is widely used in various industrial plants, logistics channels, workshops, warehouses, computer rooms, garages and other places.

And with the improvement of fast rolling shutter doors, the buyers has higher reasonable requests on the appearance of the door body, wind strength, drive and control system, manufacturing process and service life and so on.  It is understood that the fast rolling shutter door is designed as a new generation of products to meet the requirements of the market . After seeing the characteristics, we come to know the reason why the fast rolling shutter door can not be opened.

Ⅱ. Why can't fast roller shutter doors be open?

1. First, check the ground sense controller of the fast industrial rolling door: if the green light of the ground sense controller is bright for a long time, the manual automatic switch can not be operated at this time; Press the reset button on the ground sensor for more than 5 seconds, and the red light will be bright a long time and the green light will be off after release; If the green light is still bright after reset, please check if there is corresponding volume iron around the ground sensing coil of the fast industrial rolling shutter door.

2. In the automatic state of the fast industrial rolling door, when the delay closing time you set is exceeded, the door body still does not drop. Check the infrared indicator light is red or green, green is the normal state, and red indicates fault.  Adjust the infrared position of fast industrial rolling shutter door properly until the green light is on

3. The door body of the fast industrial roll up door is stuck or the door body sling falls off.

4. The door body of the fast industrial rolling shutter door runs over and over again: when the door body runs over and over again, first check whether there are objects or curtain itself to cut off the infrared state in the process of falling, and take corresponding measures to eliminate it.
