Today's manufacturing precision fire temperature exhaust fan enclosure shall comply with the relevant norms of exhaust fan, which seat within the motor housing should have sufficient strength and rigidity of the exhaust fan manufacturers, can withstand the dynamic loads generated by the roof operation exhaust fan, the height should be maintained motor shaft and the housing center line. Finally, we have learned is that the axial-flow fire temperature exhaust fan casing should be galvanizing treatment, the average thickness of the hot-dip galvanizing layer should not be less than 70μm. Fire temperature exhaust fan there is severe vibration impact, etc. anomaly must immediately stop checks, and to regularly clear the internal fire temperature exhaust fan fouling, dirt and other impurities, and to prevent corrosion. Fire fans can be widely used in many fields of mining, building, mine, field operations, and military; has a good defense value, social and economic benefits and promotion prospects.
