The main functions of fans are ventilation, dust removal and cooling. They are currently widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. The fan blade is the foundation and key component of the fan. The selection of blade material plays an important role in the stable operation of the fan. Its good design, stable quality and superior performance are important factors to ensure the normal operation of the fan.
At present, fan blades are made of a variety of materials, usually metal, engineering plastics, fiberglass, etc. Aluminum alloy has become a widely used fan blade material due to its light weight, corrosion resistance and good processability. The commonly used alloy is generally 5052 aluminum plate.
5052 aluminum plate is an aluminum-magnesium alloy. The main alloy element is magnesium. The material has a certain strength, high plasticity, good corrosion resistance, and good weldability. The fan blades are made of 5052 aluminum alloy, which has high strength, good heat dissipation, good shock absorption, large ability to withstand impact loads, and good resistance to organic matter and alkali corrosion, and is favored by the market.
Tensile strength (σb): 170～305MPa
Conditional yield strength σ0.2 (MPa)≥90
Elastic modulus (E): 69.3～70.7Gpa
The selection of blade materials is the key to blade design. Excellent materials are an important guarantee for the excellent characteristics of the wind turbine. The selection of 5052 aluminum plates for fan blades should be considered from the following aspects.
