Main Features of Mine Main Ventilation Fans

1. Impeller Arrangement: Adopts a structure with direct connection to the motor, and the impeller is fixed by connecting the shaft and hub key.

2. The overall size of the fan includes variable diameter connecting air ducts, collectors, electric/manual butterfly valves (including electric heating), connecting air ducts, primary host, secondary host, explosion-proof variable frequency motor, diffuser, round-to-square transition, silencer, diffusion tower, braking device, guide wheels, etc.

3. The fan is equipped with a manual and automatic integrated braking device, which can achieve normal start-up and reverse airflow within 5 minutes, and the reverse airflow rate is greater than 60% of the forward airflow.

4. When designing the fan, the model is optimized and personalized design is carried out according to the parameters provided by the user to ensure that the fan can operate efficiently in both the early and later stages.

5. The fan housing is made of Q235 steel plate welding. Two coats of epoxy zinc-rich primer and one coat of epoxy zinc topcoat are applied at the factory, and all bolts are galvanized.

6. The silencer plates are all made of galvanized steel, effectively extending the service life and reducing the cost of later replacement.
