The wind power lubrication system operates in extremely harsh environments and is a crucial factor in ensuring the reliability and lifespan of the wind turbines. Its main application environment characteristics include:
l Harsh climate: Wind turbines are often located in high-altitude areas, coastal regions, and deserts, facing extreme temperature fluctuations (-40°C to +50°C), strong winds, high humidity (containing salt spray), sandstorms, and ultraviolet radiation.
l Dynamic mechanical load: Gearboxes, main bearings, and pitch and yaw systems bear heavy loads, impact loads, and complex vibrations, requiring lubricants to have outstanding extreme pressure resistance, wear resistance, and vibration reduction capabilities.
l Space limitations and maintenance difficulties: Key lubrication points are located at the tower top nacelle or hub, with limited space and poor accessibility, demanding extremely high requirements for the reliability, long lifespan, and maintenance-free ability of the lubrication system.
l Electrical environment: Measures need to be taken to prevent static accumulation risks and avoid fire hazards.
To address these challenges, modern wind power lubrication systems employ high-performance synthetic oils, special sealing technologies, intelligent monitoring, and precise injection devices to ensure continuous effective lubrication protection in harsh environments, supporting the safe and efficient operation of wind turbines.
