FBCZ series explosion-proof withdrawable axial flow fan for coal mine ground
Product introduction :

FBCZ series (formerly BK54, BK55 series) fans are coal mine explosion-proof shaft circulation fans that have been successfully developed in combination with the ventilation network parameters of small and medium-sized coal mines. They have the advantages of high efficiency, energy saving, and low noise. The material used in the fan has passed the friction spark test of the Testing Center of Chongqing Branch of the Chinese Academy of Coal Sciences and has met the explosion-proof requirements. The explosion-proof performance of the whole machine has passed the explosion-proof inspection of the National Explosion-proof Electrical Product Quality Inspection Center.

main feature:

1. The simplest structure of the fan directly connected to the motor and the impeller changes the current complex extraction structure of the coal mine withdrawable axial flow ventilation and the use of belt drive or long shaft drive, which is conducive to operation and maintenance.

2. The fan is equipped with a fully enclosed closed heat sink and a pressure balance tube with a certain pressure strength outside the motor, so that the motor is always operated in gas-free air, which meets the requirements of coal mines' explosion-proof regulations.

3. This series of fans have a single-stage working wheel structure. Rear guide vanes are set between the fan and the diffuser to improve the static pressure efficiency.

4. The fan can reverse the reverse wind, and its reverse wind volume can reach 65% to 85% of the normal wind volume. There is no need to set up another reverse air duct, which has the advantages of saving infrastructure investment and fast reverse wind speed.

5. The blade mounting angle of the impeller can be adjusted, and the blade angle can be adjusted according to the production requirements. The fan adopts a special design, with no hump in the performance curve, and can run stably under any network resistance.
