This series of fans is designed specifically for the needs of non-coal mines such as metallurgy, non-ferrous metals, gold, chemicals, building materials, and nuclear industries. It can be used as a main fan and an auxiliary fan. It can be installed on the surface or installed underground. It is suitable for multi-fan joint operation. It is an ideal machine fan for all levels of stations in multi-fan series parallel multi-station ventilation system. It is also suitable for ventilation in large workshops, tunnels, civil air defense projects and other occasions.
The main features of the fan:
1. The use of twisted airfoil blades has high aerodynamic efficiency and remarkable energy saving effect.
2. With various performances and complete specifications, it can be well matched with various resistance and air volume types of ventilation network, and can maintain long-term efficient operation.
3. is equipped with a steady flow ring device, the characteristic curve has no hump, there is no danger of surge, and it can operate safely and stably under any resistance state, and is suitable for multi-fan joint operation.
4. The structure of direct connection between the motor and the impeller ensures good overall stability, easy installation, easy maintenance and low device resistance.
5 compact structure, good moisture resistance. The fan body adopts steel plate and steel group welding structure. The blades are made of steel plate material. Hollow, blades and the whole machine have high strength. They are resistant to blasting shock waves in the downhole. They can be installed on the surface and are also suitable for installation in the downhole. They are particularly suitable as multi-stage machines. Station fan for station ventilation system.
6. can reverse wind, wind rate is greater than 60%, no need to build anti-wind.
7. The blade installation angle is adjustable, and the condition of the fan can be adjusted at any time according to the change of mine production.
8 The volume of civil works is very small, which can save a lot of investment.
9 The noise is low.
