Introduction to the
FBDCZ series (original BDK62 series) fans are large-size explosion-proof axial flow fans developed successfully in combination with the ventilation network parameters of China's coal mines. They have the advantages of high efficiency, energy saving and low noise. The highest static pressure efficiency of the product device is over 86%, reaching the leading level of China's main mine fans. The materials used in the fan have passed the friction spark test of chongqing Branch of Chinese Academy of Coal Sciences and met the explosion-proof requirements. The explosion-proof performance of the whole fan has passed the explosion-proof test of the National Explosion-proof electrical products Quality testing center.
The main features
1. In order to meet the resistance requirements of coal mine ventilation network and ensure the ventilator efficiency, the machine adopts the opposed-rotation structure, and the two impeller rotate in reverse to each other, which can save the middle guide vane and reduce the loss of the middle guide vane, and improve the fan efficiency.
2. The direct connection between motor and impeller can avoid the damage of transmission device, eliminate the energy loss of transmission device, and improve the efficiency of fan device.
3 and motor are installed in fan Lord ram inside airtight cover, airtight cover has certain pressure resistance, can make the motor and fan cut off gas bearing gas in the flow channel, also has certain heat dissipation effect, airtight cover is equipped with two rows of streamlining the wind pipe, through the main ram atmosphere are interlinked, with the ground in the fresh air into the airtight cover, at the same time, can make the cover of the air inside the mediator positive pressure state of the fan operation.
4. The highest static pressure efficiency of the fan device can reach more than 86%, and the high efficiency area is wide, which can ensure that the main fan efficiency in the three mining stages is above 75%. It has reversed the low operating efficiency of the main fan in large scale mines and saved a lot of electric energy.
5, the fan can be reversed counter-wind, its counter-wind volume can reach 60% of the positive air volume, there is no need to set another counter-wind channel, has the advantages of saving infrastructure investment and fast counter-wind speed.
6. The blade installation Angle of the impeller can be adjusted. The blade Angle can be adjusted according to the requirements of production. The fan adopts special design, the performance curve has no hump, and it can run stably under any network resistance.
7. This series of fans have stable operation and low vibration. The fans and diffusers can be installed on a flat car with wheels, which can run continuously for a long time.
8. This series of fans can directly reverse the counter-wind, and the counter-wind rate can reach above 60% in all kinds of working conditions. There is no need for counter-wind, and it is only necessary to build simple ventilation room and electrically controlled duty room, which can save a lot of capital investment.
