Mine fan is specially designed according to the needs of various non coal mines such as metallurgy, nonferrous metals, gold, chemical industry, building materials and nuclear industry. It can be used as the main fan and auxiliary fan. It can be installed on the surface or underground. It is suitable for the combined operation of multiple fans. It is an ideal fan station fan for all levels of fan stations in multi fan series parallel multi-stage ventilation system, and also suitable for large workshops and tunnels Ventilation in road, underground parking lot and civil air defense engineering.
The main features of mine fan are as follows:
1. The twisted wing blade has high aerodynamic efficiency and remarkable energy saving effect.
2. It can match the ventilation network of various resistance and air volume types, and can maintain long-term and efficient operation.
3. There is no hump in the characteristic curve and no surge danger. It can operate safely and stably in any resistance state, and is suitable for combined operation of multiple fans.
4. It adopts the structure of direct connection between motor and impeller, which has good overall stability, convenient installation, easy maintenance and low local resistance.
5. Compact structure, good moisture resistance. The main body of the fan adopts steel plate and section steel welding structure. The blade is made of steel plate and hollow. The blade and the whole machine have high strength and strong ability to resist underground blasting shock wave. It can be installed on the ground or underground, especially suitable for the fan station of multi-stage ventilation system.
6. It can reverse the reverse wind, and the reverse wind rate is more than 60%. It is not necessary to build a counter air 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 engineering is very small, which can save a lot of investment.
9. The mine fan is safe to use and has low noise.
