Three types of blade characteristics of centrifugal fans

Three types of blade characteristics of centrifugal fans.
1. The forward-curved blade structure has small size, low price and high pressure coefficient, but the efficiency is generally lower than 80%. Dynamic pressure accounts for a large proportion of total pressure.
2. The radial blade has medium size, low price, high pressure coefficient, high efficiency, and a large proportion of dynamic pressure in full pressure, which is suitable for occasions with severe wear.
3. The back bend veneer structure has large size, high price, low pressure coefficient, high efficiency, and small proportion of dynamic pressure in full pressure, which is suitable for occasions with severe wear. The centrifugal fan has a large backward bending airfoil structure, high price, low pressure coefficient, high efficiency, and a small proportion of dynamic pressure in full pressure.
