Mining fan can be used as the main fan and auxiliary fan, which can be installed both on the surface and underground. It is suitable for joint operation of multiple fans, and is the ideal station fan for all levels of stations in multi-fan series-parallel multi-stage station ventilation system, and is also suitable for ventilation in large workshops, tunnels, human defense projects and other occasions.
Main features of the fan
1.Adopt twisted wing type blades, high pneumatic efficiency, energy-saving effect is extremely significant.
2.Diverse performance, complete specifications, can match well with various resistance and air volume types of ventilation network, and can maintain long-term efficient operation.
3.With stable flow ring device, no hump in characteristic curve, no risk of wheezing, safe and stable operation in any resistance state, and suitable for joint operation of multiple fans.
4.The structure of direct connection between motor and impeller, good overall stability, easy installation, easy maintenance and low resistance of the device.
5.Compact structure, good moisture-proof performance. The main body of the fan adopts steel plate and section steel group welding structure, the blade is steel plate material, hollow, high strength of the blade and the whole machine, strong ability to resist the blast wave of underground, can be installed on the surface, also suitable for installation in the underground, especially suitable as a multi-stage station ventilation system of the station fan.
6.It can reverse the reverse wind, the reverse wind rate is more than 60 percent , no need to build the reverse wind way.
7.The installation angle of the blade is adjustable, and the condition of the fan can be adjusted at any time according to the change of mine production.
8.The amount of civil construction work is very small, which can save a lot of investment.
9.The noise is low.
