Wind turbines are the champions of renewable energy, yet every wind turbine relies on hundreds of pounds of grease and gallons of oil to keep spinning. To appreciate the importance of lubricants in wind turbine reliability, it’s essential to understand the critical components that require lubrication.
-
Main Gearbox: This essential component connects the rotor to the generator and relies on oil to facilitate smooth, efficient and reliable power transfer.
-
Bearings: Bearings support various moving parts within the turbine, ensuring components can continue to move smoothly without excessive friction or wear.
-
Hydraulic System: The pitch and yaw systems optimize a turbine’s performance by positioning the rotor blades for the highest possible energy yield.
Wind Turbine Problems
A scene that is familiar to anyone who’s driven past a wind farm: some turbine blades spin gracefully with the wind, while others remain motionless. The unrelenting forces of nature can challenge even the hardiest wind turbines, affecting their efficiency and reliability, regardless of their location, manufacturer or design. Numerous factors can cause blades to stall, but lubricants are the key component that ensures wind turbine blades keep turning.
Despite its significance, attention to oil is often overlooked, and proper lubrication is the first step in lowering failure rates, improving efficiency and extending wind turbine life. Oil can break down for various reasons.
-
Extreme Temperatures: The harsh conditions in which wind turbines operate put a strain on the oil, affecting its viscosity and performance.
-
Oxidation: Exposure to oxygen can cause the oil to break down over time creating sludge and varnish.
-
Water Contamination: Water infiltration due to leaks or condensation can compromise the oil’s effectiveness and increase the risk of rust and corrosion.
-
Filtration: Inadequate filtration allows contaminants to circulate in the oil, which can cause damage to critical components.
Wind Turbine Solutions
Regular analysis is highly effective at identifying problems with lubricants before they contribute to significant failures. Efficient lubrication needs specific properties to ensure protection, efficiency and longevity in wind turbines.
-
High Viscosity Index: Oil must maintain its thickness to provide effective lubrication, even in extreme weather.
-
Varnish Resistance: Resisting the formation of varnish or sludge keeps critical components clean and the oil lubricating efficiently.
-
Seal Protection: Oil should protect seals from wear to prevent leaks and contamination.
-
Water Resistance: Being impervious to water ensures that the lubricant remains effective in the wet conditions wind turbines operate in.
