The fan blades of wind turbines are made of various materials, such as wood, metal, engineering plastics, fiberglass, etc. Among them, the blades of micro wind turbines are generally handmade from wood, using metal cold stamping or injection molding processes; the blades of small wind turbines are generally handmade from metal or fiberglass, among which fiberglass blades are the most popular and practical blades. ;Large-scale wind turbine blades are generally made by hand from fiberglass.
Blades are the most basic and critical components of wind turbines. Their good design, reliable quality and superior performance are the decisive factors in ensuring the normal and stable operation of the unit.
What is a generator windshield?
A thin shell structure made of composite materials. The small plastic pieces on the wind turbine blades are thin shell structures made of composite materials. Wind turbine blades are basically composed of thermosetting matrix resins such as polyester resin, vinyl resin, and epoxy resin and reinforced materials such as E glass fiber, S glass fiber, and carbon fiber, and are composited through molding processes such as manual laying or resin injection. . Fiberglass, the disadvantage is that it is heavy and produces resistance, and it is difficult for the wind turbine to start. Carbon fiber blades have the advantage of being light and hard. Nowadays, carbon fiber composite engineering plastics are commonly used.
The generator will generate a lot of heat when it rotates to generate electricity. Cold air must pass between the stator and the rotor, so there will be fan blades at one end of the generator. The high-speed fan blades will blow out the cooling air. , there must be a grid-like net (mostly circular and closed) outside it, which is the generator windshield, which protects the fan blades to prevent objects from falling on the fan blades.
