Pressure type local axial flow fan №5.6

The FBD series explosion-proof axial flow mine local ventilation fan (hereinafter referred to as the ventilation fan) should comply with the technical conditions of MT222-2007 reverse local ventilation fan and Q/YAF001-2011 FBD series explosion-proof axial flow mine local ventilation fan standards. Suitable for local ventilation in coal mine underground environments with explosion hazards such as gas and coal dust, and used in conjunction with positive pressure air ducts. It can also be used as ventilation equipment for tunnel construction. 1. The ventilation fan adopts computational fluid dynamics and multi-objective optimization for the overall design of the fan. The blade selection is based on the aircraft engine FMIA airfoil, which increases the efficient working area of the fan. Ventilation fans have the characteristics of compact structure, large air volume, high air pressure, long air supply distance, high efficiency, energy saving, and low noise. 2. The im…
