axial flow fan for open-pit mine

The FBC (D) Z-series explosion-proof extraction (counter rotating) axial flow ventilation fan for coal mine surface can be used as a replacement product for large, medium, and small coal mines, as well as a product for new mines. The electric motor is placed in the flow channel and isolated from the polluted air containing gas through a flow separation chamber; When the ventilation fan is running, fresh air can be sent into the isolation chamber through the air flow pipe to cool the motor, making the operation of the ventilation fan safer and more reliable. The blades adopt internationally leading curved swept combination three-dimensional twisted orthogonal and aviation wing blade profiles, and the impeller is directly connected to the motor for transmission. The aerodynamic performance is good, the high-efficiency area is wide, the static pressure efficiency is high, and the energy-saving effect is significant. It has the characteristics of simple and compact structure, smooth o…
