3C certification fire smoke is suitable for ventilation or high temperature smoke such as high -rise buildings, underground buildings, tunnels, and drying houses.It can run continuously for more than 30 minutes under high temperature conditions at 280 ° C, and running for 20 hours/time in the medium temperature of 100 ° C is not damaged. It is an ideal fire prevention facility.
3C certification fire exhaust fan structural requirements:
1. The motor thermal insulation protection and air cooling system should be set up in the fan (a ventilator with H -class insulation -level motor may not be provided with a mandatory air cooling system).The insulation level of the motor should not be lower than the F -level.
2. The electric motor power leads to the temperature -resistant insulation sleeve tolerance or use high temperature resistance cable.
3. When a centrifugal fire smoke ventilator uses A transmission, the thermal insulation structure between the case and the motor should be set.
3C certification fire smoke installation:
1. Check the components of the fan in detail before installation. Whether the connecting parts are damaged, loose, etc. If you have timely replacement or correction, you should pay special attention to whether the impeller is damaged and brightens.Whether the leaf rotation direction is correct.
2. The installation of the foundation surface must be flat, and it must be 100-200 mm higher than the roof to prevent water seepage and leakage.And the connection bolt must be buried.
3. After the installation is installed, the trial transportation should be performed. Check the blade installation angle and the power of the motor before transportation.If it does not match, use it immediately to prevent burning the motor.
4. During the use process, you should pay attention to whether the operation is normal, and it should be maintained in time. After a period of time, clean, dustproof, and lubricating oil to each oil -injection hole.
5. Check the tight nut to ensure tightness and prevent loosening.
6. In the event of the winter snowstorm in winter, fire fire exhaust fan must be used to prevent the exit of heavy snow from blocking the fans.
