working principle:
Fire smoke: During the fire, the fire centers instructions to open the fire smoke exhaust valve, pipeline smoke exhaust fans of the smoke -proof partition, and can also open the fire to smoke exhaust valve, pipeline smoke exhaust fans to smoke in the smoke -proof partition,Report to the fire center.When the temperature of the flue gas exceeds 280 ° C, the fire firing smoke and pipeline smoke exhaust fans are automatically closed and reported to the fire center.
The production workshop is eliminated to produce smoke: manually control the opening of the pipe tube smoke exhaust fans through the smoke exhaust pipes to discharge the smoke outdoors.
The pipeline exhaust fan and the tobacco exhaust pipeline are installed indoors, and the tobacco downtime is discharged from outdoor safety places.
Features:
The axial flow fans are small (less than 400 PA), the power consumption is small, the structure is simple, the cost is low, and the installation is convenient.
The mixed flow fans are midstress fans (400 ~ 600Pa), which consumes small power consumption, has a simple price of simple structure, and is convenient for installation.
The internal fan of the box fans can be a bearing fans.You can also mix the current fan.Corresponding fan.The main advantage is that the device is contained in a shock -absorbing device on the base of the device, and the device is closed inside the chassis, so the noise transmitted in the room is relatively smaller.Because the processing process introduced above, the overall equipment cost is relatively higher.
The above is a commonly used equipment that uses power for compulsory smoke.
Pipeline material: can be brick, concrete pipeline wells, steel plate air ducts, or inorganic non -combustible glass fiber reinforcement duct.
Pipe exit direction: Generally, it is led to the roof to the outdoor through the pipeline.
The above is the introduction of pipeline smoke exhaust fans. If you want to understand and learn more about related knowledge, please pay more attention to us- ——
