从风井到风峒是一个变断面的直角转弯,由于通过风量大,风速高,因此风井与风峒连接处的通风阻力约占风峒总阻力的一半以上,其通风阻力状况,对主扇能量的有效利用有直接影响。因此,在设计和建筑风峒时,必须使其具有良好的空气动力性能,以降低通风阻力。 From the wind shaft to the wind 峒 is a variable cross-section of the turn at right angles, due to the large amount of wind, high wind speed, so the wind and wind 峒 connection at the ventilation resistance of the wind 峒 total resistance of more than half of its ventilation resistance conditions, The effective use of fan energy has a direct impact. Therefore, in the design and construction of wind turbines, it must be made with good aerodynamic performance to reduce ventilation resistance.
