Fire-proof fast rolling shutter door is an indispensable fire-proof facility in modern high-rise buildings. Fire-proof door has the function of fire-proof and smoke-proof, besides ordinary door, and is widely used by people.
Fire fast rolling shutter doors are mainly used in large shopping malls, large professional material markets, large exhibition halls, factories, warehouses and other public places with fire protection requirements. When a fire occurs, the fire roll shutter door is automatically lowered under the control of the fire central control system according to the pre-set procedure, thus preventing the flame from spreading to other areas, and gaining valuable time for the implementation of fire fighting.
Fire-proof fast rolling shutter door fire-proof rolling shutter is a fire-proof and heat-insulating facility suitable for large openings of buildings. The product is designed with the characteristics of the rollers embedded, and has a reasonable and compact structure. Fire-proof roll curtain can be lifted by means of transmission device and control system. It plays the role of fire prevention and fire insulation. The product has smooth and beautiful shape, novel shape and strong steel character. Fire-proof rolling shutter doors are widely used in fire-proof partition zones of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. They are indispensable fire-proof facilities in modern buildings.
Common Faults and Maintenance Method of Fast Curtain Door:
1. Reasons for weight loss of industrial fast shutter doors (1. Deformation of manual pull rod, replacement of manual pull rod). 2. The gap between the manual pull rod and the gasket is large, which reduces the gap. 3. Lubrication failure of gearbox motor, replacement of grease.)
2. Investigation of the reasons why the hand zipper of industrial fast rolling shutter door can not be pulled (1. Blocking the cross groove by the ring chain, straightening out the chain. 2. The electromagnet fastener is loosened and re-fastened.
3. Investigation on the causes of braking slippage of industrial fast shutter doors (1. The brake brakes of industrial fast shutter doors are greasy and cleaned with gasoline. 2. The electromagnet is not installed correctly, so it should be reinstalled. 3. The compression spring force decreases and the spring is replaced.
4. Reasons for the non-start of the motor of the industrial fast rolling shutter (1. Circuit disconnection to check the wires). 2. Running capacitance is damaged and replaced. 3. Failure of overheat protection and replacement of overheat protector. 4. The brake sticks and the manual chain pulls and turns several times. 5. Limit switch often closed contacts are not open, grinding contacts or replacing limit switch. 6. The breaker coils or oxidizes, contaminates, replaces the breaker or polishes the contacts. 7. Continuous operation time is too long, thermal protection is disconnected, motor temperature can be reduced. 8. Bridge rectifier ring or electromagnetic coil ring, brake jam, replace bridge rectifier or electromagnetic coil ring.
