Coal Mine Explosion-proof Blower:

FBD series explosion-proof press-in convective axial flow local fan for coal mine, the product is manufactured in full accordance with MT755-1997 "Technical Conditions for Counter-rotating Local Fan". The product has the characteristics of reasonable structure, complete specifications, high efficiency, obvious energy-saving effect, low noise and long air supply distance. This product is currently the most ideal performance for coal mine ventilation equipment at home and abroad. Its structural characteristics are mine flameproof type, counterrotation, sound attenuation, and axial flow type. There is no pollution to the environment, and it is a high-efficiency and energy-saving product.

A coal Mine Explosion-proof Blower is a fan used in explosion hazard occasions, which must meet explosion-proof requirements in addition to the fan characteristics required by working conditions.

On the one hand, Coal Mine Explosion-proof Blowers must adopt explosion-proof motors; On the other hand, the overcurrent parts of explosion-proof fans (impellers, volutes, etc.) must be made of soft and hard materials, generally speaking, that is, between rotating parts and fixed parts, one soft and one hard to prevent sparks caused by friction or collision between components in the event of failure. The more common material combination is that the blades, front disc, rear disc and blade rivets of the impeller are duralumin made of 2A01 material, and the volute is made of galvanized sheet.

If the impeller is made of duralumin and does not meet the strength requirements, the galvanized sheet impeller can also be used, and the surface of the volute is covered with a thin duralumin lining.

After years of development, we have accumulated rich experience and solid foundation in product application and production technology, making us a diversified professional enterprise for Exhaust Fans for Tunnel.
