What is the price of 2 * 75 mine ventilato

  FBD series explosion-proof press in counter rotating axial flow local fan is developed by Tai'an Futong Mining Electric Co
, Ltd
on the basis of summarizing the structure and technical performance of domestic existing counter rotating axial flow local fan, and produces a new generation of new energy-saving local fan with wide application
The product is mainly used in coal mines and underground coal mines with gas explosion risk for medium and long-distance ventilation of coal mining face
It is also widely used for ventilation in metal mines, chemical mines, tunnels, metallurgy, chemical building materials and other industries
It is suitable for places where the medium temperature is no more than 40 ℃ and the relative humidity is no more than 95% RH (at 25 ℃)
Grounding bolts are welded on the flange of the fan body for direct grounding on site
Evenly distributed small holes are drilled on the flange of the air outlet duct (refer to JB / t6885-93)
It is used to connect the reducing nipple or directly connect the gum air duct
When the reducing nipple is used to connect the fan and the gum duct, the type of the reducing nipple can be made into convergence type or diffusion type

Its working principle is: during operation, the two-stage impellers have two explosion-proof motors with the same capacity and opposite rotation direction, which are directly driven
When the air flow enters the first stage impeller through the air inlet duct to obtain energy, it is boosted and discharged through the second stage impeller, and the two-stage impellers are guide vanes for each other, so as to achieve the high air pressure that is difficult to be achieved by ordinary axial flow fans
