Mining fans are specifically designed to meet the needs of various non-coal mines, including metallurgy, non-ferrous metals, chemical industry, building materials, and nuclear industry. They can serve as main or auxiliary fans, and are suitable for installation both on the surface and underground. They are ideal for multi-fan operation, making them perfect for multi-level fan stations in series and parallel multi-stage ventilation systems. Additionally, they are also suitable for ventilation and air exchange in large workshops, tunnels, civil defense projects, and other similar venues.
Key Features of DK40 Mining Fan:
1. Utilizing twisted wing-shaped blades, the aerodynamic efficiency is high, and the energy-saving effect is extremely significant.
2. Diverse in performance and comprehensive in specifications, it can perfectly match various resistance and airflow types of ventilation networks, ensuring long-term and efficient operation.
3. Equipped with a flow stabilizing loop, the characteristic curve is free of humps and there is no risk of surge, ensuring safe and stable operation under any resistance condition. It is also suitable for combined operation of multiple fans.
4. Utilizes a direct connection between the electric motor and impeller, offering excellent overall stability, easy installation, simple maintenance, and low local resistance.
5. Compact structure with excellent moisture resistance. The fan housing is made of steel plate and section steel welded construction, with blades made of steel plate material, hollow, featuring high strength in both blades and the entire unit, strong resistance to underground blast shockwaves. Suitable for installation on the ground surface, it is also ideal for underground use, particularly as a fan for multi-stage station ventilation systems.
6. Capable of reversing wind direction with a reversal rate over 60%, no need to construct a wind reversal channel.
7. Blade installation angle is adjustable, allowing for real-time adjustments to the fan's condition according to the changes in mine production.
8. Civil engineering volume is minimal, resulting in significant cost savings.
9. Lower noise level.
