Apply most often horizontal axis blower fan in the world, its technology relative maturity at present, lots of production is large, has become the mainstream model in current large fan field.But along with the rising of distributed energy supply and blower fan miniature requirement, the congenital deficiencies such as horizontal axis fan starting wind speed is high, operating noise is large, wind loading rating is poor progressively expose, and inhibit its further Application and Development.And having that structure is relatively simple, threshold wind velocity is low, aerodynamic noise is little, the better vertical shaft fan of wind-engaging performance, progressively steps into the visual field of people.
Vertical shaft fan is mainly divided into resistance force type vertical shaft wind machine and the large class of lift vertical shaft blower fan two.Resistance force type vertical shaft wind facility have the advantage that detent torque is large, threshold wind velocity is low, but pneumatic efficiency is lower; Lift vertical shaft blower fan has the shortcoming that detent torque is little, threshold wind velocity is higher, but pneumatic efficiency is also higher.If the advantages of two kinds of blower fans can be got up, produce that to have threshold wind velocity concurrently low, the vertical shaft fan of the high two kinds of advantages of pneumatic efficiency obviously has more excellent application prospect and competitive ability.
