Explosion-proof axial fan features

Explosion-proof axial fan

1. Explosion-proof Axial-flow Fan Overview The explosion-proof axial-flow fan is a new type of fan that was improved in China in the 1980s based on the BT30-11. Compared with the BT30-11 fan, it has obvious advantages:

1, the performance has been greatly improved, the total pressure of 89.5%;

2, the structure is more reasonable;

3. The noise is lower and the noise (A-level noise) is reduced by 3.6dB (A). The explosion-proof axial fan is suitable for conveying flammable, explosive and non-corrosive gases. The ambient temperature must not exceed 60°C. It is widely used in general factories, warehouses, offices, and residential houses for ventilation or strong heat dissipation. It can also have long The exhaust gas pipeline interval is installed in series to increase the pressure in the pipeline. Removing the motor can be used as a free fan. Anti-corrosion axial flow fan (FT35-11 type) is made of anti-corrosion material coated with epoxy paint. The motor uses a special anti-corrosion motor for the transportation of corrosive gases. Explosion-proof axial fan (BT35-11 type) for conveying flammable and explosive gases. The impeller is made of aluminum alloy to prevent sparks during operation. The motor uses a flameproof motor. The performance parameters and overall dimensions of the FT35-11 and BT35-11 fans are the same as those of the T35-11. The fan needs to have bracket legs and motor voltage. Please specify when ordering.

Second, the explosion-proof axial flow fan Description 1, in the fan outlet must be installed wind collector, and want to install protective nets.

2. When installing, pay attention to check whether there is any looseness in the connection parts, and the gap between the blades and the fan should be uniform and not to collide.

3. The weight of the duct connecting the tuyere shall not be borne by the fan duct of the fan, and the support frame shall be added during installation.

4. Before installation, it is necessary to check in detail whether the fan has been damaged or deformed. If it is damaged or deformed, it can be installed after it is properly repaired.

5. After the installation is completed, the experiment must be performed first. After the operation is normal, formal use is allowed. Technical parameters Explosion proof mark: EedIIBT4 Protection class: IP54 Corrosion protection class: WF1 Rated voltage: AC220/380 Spindle revolutions: 1450 r/min

6. The fan base must naturally engage with the ground plane, and must not be forced into the base to prevent the base from deforming. During installation, correct the base and add the horns to keep the horizontal position, and then tighten the anchor bolts.
