How are hydraulics used in wind turbines?
The wind-energy industry makes good use of hydraulics, in particular how well it combines power density and durability for the muscle needed to pitch turbine blades that easily weigh two to three tons. In recent years, however, most utility-scale wind turbines for land installations have turned to electromechanical systems for this function. Electromechanical systems typically…
Goodbye gearbox, hello hydraulics
The U.S. wind energy market includes roughly 30,000+ aging turbines. Of those, around 7,000 are down for repair at any given time. The bulk of repairs are gear failures in gearboxes and yaw drives. Other turbine-stoppers include main-shaft bearings and seal failures, electrical generator overloads, and over-speed brake failures. High costs and duration of repairs…

How to protect high-pressure hydraulics
A new rupture-disc assembly for wind-turbine hydraulic brakes protects equipment from damage and down time in the event of overpressure. Intended for the hydraulic brakes and yaw brakes of wind turbines, the rupture-disc assembly, model CD31179 provides accurate and leak-free overpressure relief for the control valve and hydraulic accumulator system. The hydraulic braking device, from…
Low pressure course on hydraulics for wind turbines
A four-and-a-half-day training course is aimed at sales and maintenance personnel who must understand hydraulics systems used in wind turbine operation. Wind Turbine Fundamental Hydraulics will be offered by industrial manufacturer Eaton Corp. “Nearly half of the utility-grade wind turbines in service depend on hydraulic pitch and yaw controls. Many of the others use electric…
