How to classify explosion-proof centrifugal fans


Explosion-proof centrifugal fans are suitable for manufacturing industries such as factories, coal mines, tunnel furnaces, petrochemicals, etc. The explosion-proof centrifugal fans are highly explosion-proof and reliable in operation. The connection terminals of the explosion-proof centrifugal fans use annular stoppers and sealing rings to improve the processing precision of key parts The motor shaft adopts a parallel-plane vertical radiator structure, and several electrical equipment and mechanical design countermeasures such as expanding the total heat dissipation area of ​​the heat pipe. The level of anti-fouling and moisture-proof is improved by an equal pole, and the operation of the motor is more reliable. At this stage, there are many types of explosion-proof centrifugal fans, let's get to know the classification rules of explosion-proof centrifugal fans.

1. According to the basic principles of the motor: it can be divided into explosion-proof multi-threaded motors, explosion-proof simultaneous motors and explosion-proof DC motors.

2. Divided by application site: It can be divided into explosion-proof motors for coal mines and explosion-proof motors for factories.

3. According to the basic principles of explosion protection: it can be divided into explosion-proof motors, increased safety motors, positive pressure motors, flame-free motors and smoke and dust explosion-proof motors.

Fourth, according to the server of supporting facilities: it can be divided into explosion-proof motors for coal mine conveyors, explosion-proof motors for coal mine winches, explosion-proof motors for rock loaders, explosion-proof motors for fans in coal mines, and explosion-proof motors for gate valves.

Therefore, when we select explosion-proof centrifugal fans, we must carry out effective selection based on our own application conditions. Choosing a suitable explosion-proof centrifugal fan is beneficial to improve our work efficiency.

The shutdown operation of the anticorrosive centrifugal fan must also be done

What is the reason why the temperature of the explosion-proof centrifugal fan exceeds the standard value
