Marine Explosion-proof Axial Fan
Marine explosion-proof fan is a fan that will not cause explosion of explosive gas mixture in the surrounding environment when it is used on board. Explosion-proof fan is suitable for extracting flammable and explosive mixed gases or vapors from oil tanks, cargo tanks, pump compartments, battery compartments, ammunition compartments, aircraft hangars, paint booths and other places on board, and it is also suitable for ventilating other compartments of the ship or the corresponding places of various departments on land.
Explosion-proof fan is mainly composed of motor, impeller, casing, pressure expansion cone, rectifier and other parts. The casing is made of sufficiently thick steel plate.
Overview
Key Points:
1.The motor used is different, explosion-proof fan must use explosion-proof motor.
2.The impeller material and impeller relative to the position of the inner wall of the casing material requirements, requiring them in the unlikely event of friction will not produce sparks, such as the use of aluminum blades and iron inner wall, or iron blades and aluminum rings in the inner wall.
3. Explosion-proof blower impeller and casing clearance has the lower limit requirements. And fans in pursuit of efficiency often have an upper limit on the clearance requirements, contradicting each other.
4. Explosion-proof fan on the import and export side of the safety protection requirements are more stringent.
