Characteristics of three types of blades for centrifugal fans

Post time: 2019-12-23 17:03 [Large Middle Small]
First, the three common types of blades for axial flow fans are forward curved, radial, and backward curved. The back bend type is divided into veneer type and wing type.
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.
Radial blades are of 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.
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 backward bending airfoil structure has large size, high price, low pressure coefficient, highest efficiency, and small proportion of dynamic pressure in full pressure.
