Roller Shutter Fire Door With electric opening and closing

Fire shutter with the rolling door machine debugging should meet the following requirements:

        1, the rolling door manual operation device (manual zipper) should be flexible and reliable, the installation location should be easy to operate. Use the manual operation device (manual zipper) to operate the fire shutter open and close operation, should not appear sliding impact phenomenon (inspection method: visual inspection, pull the manual zipper, observe the fire shutter action, the operation).

        2, the door machine should have an electric opening and closing and rely on fire shutter weight rate constant speed down (manual speed) function. Start the fire shutter weight drop (manual speed release) arm force should not be greater than 70N (inspection method: manual test, pull the manual quick release device, observe the fire shutter action, with a spring dynamometer or weight to measure the starting force ).

        3, the door machine should be equipped with automatic limit device, when the fire shutter Kai, closed to the upper and lower limit, it should automatically stop, the repeated positioning error should be less than 20mm (inspection method: start the door machine, run after a certain time , Close the door machine, repeat the positioning error with a ruler).

        Third, the fire shutter running function debugging should meet the following requirements:

        1, fire shutter assembly is completed, the curtain surface in the guide rail operation should be smooth, there should be no derailment and obvious tilt phenomenon. Double curtain curtain of the two curtain surface should also rise and fall, the height difference between the two curtain surface should not be greater than 50mm (inspection method: with a steel tape measure double curtain curtain between the two curtain surface height difference ).

        2, fire shutter electric opening and closing speed should be 2m / min ~ 7.5m / min, the weight of the decline should not be greater than 9.5m / min (inspection methods: stopwatch, steel tape measurement).

        3, fire shutter opening and closing operation of the average noise should not be greater than 85dB. (Inspection method: in the fire shutter operation, with the sound level meter in the vertical distance from the shutter surface 1m, vertical distance from the ground 1.5m out, the level of measurement three times, whichever is the average).

        4, installed in the fire shutter on the temperature of the release device after the action, the fire shutter should be automatically reduced to off (check method: fire shutter installation and commissioning, cut off the power, heating temperature control device to make it temperature Component action, observe the fire shutter action).
