DK4045 mine counter rotating main fan

This series of fans is specifically designed to meet the needs of various non coal mines such as metallurgy, non-ferrous metals, gold, chemical, building materials, and nuclear industries. They can be used as main and auxiliary fans, and can be installed on the surface or underground. They are suitable for multi fan joint operation and are ideal fans for various levels of fan stations in multi fan series parallel multi-stage ventilation systems. They are also suitable for ventilation and air exchange in large workshops, tunnels, civil defense projects, and other occasions.

Main features of the fan:

1. Adopting twisted wing shaped blades, the aerodynamic efficiency is high and the energy-saving effect is extremely significant.

2. Diverse performance and complete specifications, it can be well matched with ventilation networks of various resistance and air volume types, and can maintain long-term efficient operation.

3. Equipped with a stabilizing ring device, the characteristic curve has no hump, no surge danger, and can operate safely and stably under any resistance state, suitable for multi fan joint operation.

4. The structure adopts a direct connection between the electric motor and the impeller, with good overall stability, easy installation, easy maintenance, and low local resistance of the device.

5. Compact structure and good moisture resistance. The main body of the fan adopts a welded structure of steel plate and section steel, and the blades are made of steel plate material, hollow. The blades and the whole machine have high strength and strong resistance to underground blasting shock waves. They can be installed on the surface and are also suitable for installation underground, especially as fan stations for multi-stage ventilation systems.

6. Reversible reverse wind, with a reverse wind rate greater than 60%, does not require the construction of a reverse air duct.

7. The installation angle of the blades can be adjusted, and the fan condition can be adjusted at any time according to the changes in mine production.

8. The amount of civil engineering work is very small, which can save a lot of investment.

9. Low noise.
