FBD ventilation fan usage environment and working conditions

Description :

　　FBDMining explosion-proof pressure type counter rotating axial flow local ventilation fanUse environment and working conditions

　　FBDExplosion proof press in counter rotating axial flow local ventilation fan for coal minesThe usage environment and working conditions:

　　FBDExplosion proof press in counter rotating axial flow local ventilation fan for coal minesIt can be used flat on the bottom plate of the roadway or suspended on the wall of the roadway. The gas temperature of its use environment is -20~40 ℃. The dust content of the gas passing through this product should not exceed 200mg/m3. It should be installed in the intake airflow with a gas concentration of less than 1% underground in coal mines. When the gas concentration exceeds 1%, the power should be immediately cut off.

　　FBDExplosion proof press in counter rotating axial flow local ventilation fan for coal minesworking principle

　　The FBD series mining counter rotating axial flow local ventilation fan consists of two or more working hosts, with two or more stages of impellers rotating in opposite directions: the first stage impeller rotates clockwise and the second stage impeller rotates counterclockwise. The air obtains energy from the first stage impeller and is pressurized by the second stage impeller before being sent out. In addition to increasing airflow energy, the secondary impeller also has the function of static guide vanes in ordinary axial flow fans. While obtaining the velocity component in the circumferential direction of the guide, it smooths out the airflow impact, increases airflow energy, reduces wake vortices, and lowers noise. Compared with similar products in China, it reduces A-level noise by 10-20 decibels and has stable performance, making it safer and more reliable.

　　FBDPerformance and characteristics of explosion-proof press in counter rotating axial flow local ventilation fan for coal mines

　　FBDExplosion proof press in counter rotating axial flow local ventilation fan for coal minesIt has the characteristics of reasonable structure, complete specifications, high efficiency, obvious energy-saving effect, low noise, and long air supply distance. According to different ventilation resistance requirements, it can be used as a whole machine or in stages, thereby reducing ventilation power consumption and saving energy. Within a tunnel length of 2000 meters, the fan can supply air normally without moving, reducing the labor intensity of workers and saving ventilation time. It is an ideal equipment for local ventilation in coal mines.

　　We will rely on advanced technology and a diligent and persistent spirit of innovation to sincerely cooperate with our customers with our products, discounted prices, and satisfactory services.
