In addition to having varied configurations, explosion-proof fans and regular fans have various application scenarios.
Explosion-proof fans are typically utilized in locations with flammable and explosive gasses because they can help prevent some flammable and frequently occurring safety incidents. The substance of the fan and the explosion-proof motor, in addition to their clearance for the impeller and casing, and their import and export end safety protection, are the most evident differences between the explosion-proof fan fan and the typical non-explosion-proof fan fan.
1, the motor is different Explosion-proof fans must employ explosion-proof motors, which are distinct from regular fans' motors.
2. The impeller is not made of the same material as the inner wall of the casing, which is why it is necessary to use materials like aluminum blades and iron walls or iron blades and aluminum rings in the inner wall if friction will not cause sparks.
3. The impeller and casing gap are not the same. The same explosion-proof fan has lower limit requirements for the impeller and casing clearance, but the fan frequently has upper limit requirements for clearance in order to pursue efficiency.
4. The safety protection is different on the import and export sides. Air-cooled explosion-proof circulation fans with motors and impellers directly connected to the fan have a simpler structure and meet more stringent safety protection requirements for import and export than current coal mine extracted axial flow fans, which have complex structures that are difficult to operate and maintain.
