The main parts of the yaw brake hydraulic system and their functions are Accumulator: The accumulator stores fluid under pressure, and serves as a backup source of clamping pressure if system pressure is lost. Bleed Valve: Used to drain fluid from the accumulator to relieve pressure during service operations. Brake Calipers: Pressure in the brake…
The main damages during the lifetime of a wind turbine are caused by: General Wear Delamination can happen in wind blades, where a detachment of the intra and extrados shellscan be seen. Usually associated with leading edge erosion. Fatigue Loads It is the phenomenon of progressive rupture of materials subjected to repeated cycles of stress…
Polymers can be classified, in terms of fusibility, into thermoplastics or thermosets (thermosets). Thermoplastic polymers melt on heating and solidify on cooling, in a reversible process. They can also be dissolved in suitable solvents. Examples: PET (from beverage bottles), PS (from disposable cups), LDPE (from plastic bags), PVC (from sewage pipes). Thermosetting polymers, by heating…
