Fbd 380-1140V Mine Flameproof Type Counterrotating Press in Type Local Axial Flow Fan

Product Description:

FBD series explosion-proof compression type counter rotating axial flow local fan for coal mine is mainly used as a  compression type local fan in coal mine. It is suitable for local ventilation of mining face and various chambers,  as well as local ventilation of other mines and various tunnels.
This product has the characteristics of reasonable structure, complete specifications, high efficiency,  obvious energy-saving effect, low noise, long air supply distance,  etc. According to different ventilation resistance requirements, it can be used both as a whole machine and by grades,  so as to reduce ventilation power consumption and save energy. When the roadway length is less than 2000 meters,  the fan can not be moved to supply air normally,  which reduces the labor intensity of workers and saves ventilation time. It is an ideal equipment for local ventilation  in coal mines.
The fan has the characteristics of reasonable structure, high efficiency, obvious energy-saving effect, low noise,  long air supply distance,  etc. It is an ideal equipment for local ventilation in coal mine. Its structural characteristics are explosion-proof,  counter rotating, noise elimination and axial flow.

Product feature and Use environment:
Features:
(1) This series of fans is composed of collector, primary fan, secondary fan, motor,  muffler and so on. The body and structure are welded with steel plates,  and the motor and the impeller are directly connected,  with reliable transmission. The overall structure is simple and compact, sturdy and durable,  safe to use and easy to maintain.
(2) The fan is driven by YBF2 series fan with flameproof three-phase asynchronous motor or motor with integrated  structure.
(3) The ternary flow aerodynamic theory adopted,  the combination of bending and sweeping orthogonal blades and airfoils and many other technologies are designed and  manufactured.
(4) It has the characteristics of compact structure, low noise, high efficiency, good anti-wind performance,  high wind pressure, stable operation in small flow areas,  and wide application range. According to the length of the excavation face and the different ventilation requirements of  the roadway, it can be used as a whole machine or in stages, thereby reducing energy consumption. Energy saving,  it is the equipment for local ventilation in long distances in mine excavation.
(5) It adopts the outsourced duplex muffler device, which has the characteristics of low noise and good muffling effect.
Working conditions:
a) Ambient temperature: (-15~+40) ºC;
b) The altitude does not exceed 1000m;
c) The relative humidity does not exceed 90% (+25 ºC);
d) There is no strong vibration and corrosive gas, etc.;
e) Installed in fresh air flow underground in coal mines where there is a danger of methane and coal dust explosions.  installed in the air intake duct.
