SDF (A)series of forced counter-rotating axial fans for tunnels
I. Overview
1.SDF (A)tunnel fan characteristics
SDF (A)Series Press-in Counter-rotating Axial Fan for Tunnel (hereinafter referred to as Fan)
A new generation of energy-saving tunnel fan with wide application is developed and produced on the basis of summarizing the structure and technical performance of existing counter-rotating axial flow local fan in China. The product has reasonable structure, complete specifications, highefficiency,obvious energy-saving effect, low noise,long air supply distance and other characteristics. According to different ventilation resistance requirements, it can be used as a whole or in stages, thus reducing ventilationtime and saving energy. The tunnel length is less than2000m, the ventilator can not be moved to supply air normally, the labor intensity of workers is reduced, and theventilation time is reduced. It is an ideal equipment for tunnel ventilation. At the same time, it can also be used in metallurgy, non-ferrous metals, gold, chemicals, shipbuilding and ceramics and other high-pressure ventilation occasions.
The fan structure features counter-rotation, noise elimination and axial flow, which can be used for medium and long distance ventilation of tunnel driving face. At the same time, it is also suitable for local ventilation in other non-coal mines and various underground roadway ventilation.
2.Main purpose and scope of application
SDFtunnel fan normal working conditions are:
1)It ismainly used for ventilation of tunnel driving face, installed outside the tunnel, matched with positive pressure air duct for forced ventilation;
2)Medium temperature-20C— 40C;
3)elevation less than1000meters;
4)Humidity is not greater than95%(at 25℃).
3.SDF (A)Standard for tunnel fan implementation
MT222Technical Conditions for Local Fans Used in Coal MineandQ/ZFJ002 (FBDSeries Press-inCounter-rotating Axial Fans Used in Coal Mine) standards shall be implemented for fans.
4.SDF (A)Types and specifications of tunnel fans
Fans are serial products with complete specifications and varieties. For details, please refer to the technical performance and appearance installation size table of fans (Table1).
5.Explosion-proof type and explosion-proof mark of ventilator and motor
Explosion-proof type explosion-proof signs for coal mines
Explosion-proof type of fan: flameproof type, explosion-proof mark:Exdl»
Explosion-proof type of motor: flameproof type, explosion-proof mark:Exdl.
6.SDF (A)Working conditions of tunnel fan- The working voltage of the tunnel fan is380/660V anddoes not exceed 5% of the rated value±, andthe power supply frequency is50Hz.
- SDFtunnel fan foundation should be firm, no water around. The height of the air inlet edge of the fan from the ground or top wallshall not be less than0.3m.
- Tunnel fans can be placed on the tunnel floor or hung on the tunnel wall. When placed on the tunnel floor, the suction opening (collector end) of the fan must not be immersed in water or cement.
The fan design service life is not less than5years, and the safe operation time before overhaul is13000hours.
SDF(A)Impact of tunnel fans on environment and energy
This product has no environmentalpollution and belongs to high efficiency and energy saving products.
