The Motor for Fire-proof Roller Shutter Doors
Firstly, the appearance and parts
1. The outer casing of the rolling up door machine should be complete, without corners and obvious cracks and deformation. 2, the surface of the coating should be smooth, no obvious bubbles, wrinkles, spots, sag and other defects. 3. Parts of the rolling door machine should not be made of flammable or combustible materials. 4, the control device of the roller door machine should be beneficial to the use of staff control. Secondly, the basic performance 1. The rated output torque of the rolling door machine should meet the design requirements. The manufacturer shall provide proof of inspection. 2. The brake of the rolling door should be safe and reliable. The braking force should not be less than 1.5 times of the weight of the rated output torque. The sliding displacement should not exceed 20mm. 3. The rolling door machine should have manual use device. The manual use device should be flexible and reliable, and the installation position should be conducive to operation. When using the manual operation equipment to operate the fire shutter door on and off, it is strictly prohibited to have a sliding collision. 4. The rolling door machine should have the function of electric opening and closing and constant sliding of the total weight of the fire shutter door. The electric opening and closing and self-weight sliding speed should meet the requirements of 6.4.5. The arm force for starting the fire shutter door should not exceed 70N. . 5. The rolling door machine should have a fully automatic limit device. When the fire shutter door is opened and closed to the upper and lower limits, it can be automatically terminated. The repeated positioning accuracy of multiple repeated repetitions should be less than 20mm.
Thirdly, the mechanical equipment life After the counterweight is rated at the output torque, the number of times the door opener should be opened and closed should not be less than 2000 times. Note: The roller blind is closed from the closed condition to fully open, and then completely closed to a cycle. Fourthly, noise The noise of the rolling door machine running at no load should not exceed 65dB. Five, power performance
When the voltage fluctuation of the AC power supply system is not higher than +10% of the rated voltage and not more than -15% of the rated voltage, the roller shutter should be able to operate normally.
Sixth, safety performance 1. The insulation resistance of the electrical equipment of the roller door machine should be higher than 20MΩ under normal atmospheric conditions. 2. The live parts and the outer casing of the rolling door machine should be able to withstand the test voltage of 1760V and 50Hz, which takes 1min without causing breakdown, surface arcing and sweeping problems. The performance index after the test shall comply with the provisions of A.1.2. Finally. The stability in a climatic environment The roller shutter should be able to withstand the tests in the climatic environment specified in Table A.1. The performance after the test shall comply with the provisions of A.1.2.
