Mine Axial Fan

The normal working conditions of a Mine Axial Fan are:
a) Ambient temperature: (-15~+40)℃;
b) The altitude does not exceed 1000m;
c) The relative humidity does not exceed 90% (+25°C);
d) 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,
It is used together with positive pressure air duct for press-in ventilation.

This series of fans is specially designed according to the needs of various non-coal mines such as metallurgy, non-ferrous metals, gold, chemical industry, building materials and nuclear industries.
It can be used as the main fan and auxiliary fan, and can be installed on the surface or underground. It is suitable for the combined operation of multiple fans.
It is an ideal station fan for each station in the multi-fan series-parallel multi-stage station ventilation system, and is also suitable for ventilation in large workshops, tunnels, civil air defense projects and other occasions.

The main features of the Mine Axial Cooling Fan:
1. The twisted airfoil blade is adopted, which has high aerodynamic efficiency and extremely significant energy saving effect.
2. It has various performances and complete specifications, which can be well matched with ventilation networks of various resistance and air volume types, and can maintain long-term and efficient operation.
3. Equipped with a steady flow ring device, the characteristic curve has no hump, and there is no danger of surge. It can run safely and stably under any resistance state, and is suitable for multi-fan combined operation.
4. Adopting the structure of direct connection between the motor and the impeller, the overall stability is good, the installation is convenient, the maintenance is easy, and the local resistance of the device is low.
5. Compact structure and good moisture-proof performance. The main body of the fan adopts steel plate and section steel group welding structure, the blade is made of steel plate material, hollow, the blade and the whole machine have high strength, and the ability to resist underground blasting shock waves is strong. Station fans of the station ventilation system.
6. The reverse wind can be reversed, the reverse wind rate is greater than 60%, and there is no need to build a reverse wind duct.
7. The blade installation angle is adjustable, and the fan condition can be adjusted at any time according to the change of mine production.
8. The amount of civil works is very small, which can save a lot of investment.
9. Low noise
