Product introduction: FBCDZ series (formerly BDK62 series) fan is a large-scale coal mine explosion-proof axial flow fan successfully developed in combination with the ventilation network parameters of China's coal mines. It has the advantages of high efficiency, energy saving and low noise. The highest static pressure efficiency of the product is 86% or more. , reached the leading level of China's mining main fan. The material used in the fan has passed the friction spark test of the Testing Center of Chongqing Branch of China Coal Science Institute, and has reached 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 Testing Center. Main features: 1. In order to meet the resistance requirements of coal mine ventilation network and ensure the efficiency of the fan, the machine adopts a counter-rotating structure. The two impellers rotate in opposite directions, which can save the middle guide vanes and reduce the middle guide vane. The loss has increased the efficiency of the fan. 2. The type of direct connection between the motor and the impeller avoids the damage of the transmission device, eliminates the energy loss of the transmission device, and improves the efficiency of the fan device. 3. The motor is installed in the airtight cover in the main air duct of the fan. The airtight cover has a certain pressure resistance, which can isolate the motor from the gas containing gas in the fan flow passage, and also has a certain heat dissipation effect. The airtight cover is provided. The two-row streamlined air duct passes through the main air duct and the ground atmosphere, so that fresh air flows into the airtight cover, and at the same time, the air in the cover can maintain a positive pressure state during the operation of the fan. 4. The maximum static pressure efficiency of the fan can reach more than 86%, and the high efficiency zone is wide, which can ensure that the efficiency of the main fan in the three mining stages is more than 75%. It has reversed the low efficiency of the operation of the main fan of large mines in China, which can save a lot of electric energy. 5, the fan can reverse the wind, its anti-wind volume can reach 60% of the positive air volume, there is no need to set up a reverse wind channel, which has the advantages of saving capital investment and fast anti-wind speed. 6. The blade mounting angle of the impeller can be adjusted, and the blade angle can be adjusted according to the production requirements. The fan has a special design, the performance curve has no hump, and it can run stably under any network resistance. 7. The series of fans operate stably, the machine vibration is small, and the fan and diffuser can be installed on the flatbed with wheels, which can run continuously for a long time.
