In wind turbines, the hydraulic system ensures output under any wind conditions by controlling blade spacing and yaw, while avoiding damage to the turbines, sensors play a crucial role in the middle. In order to ensure the mechanical performance and control fatigue strength of the wind turbine, the key is to continuously monitor the state of this kind of hydraulic system. Doweston has a variety of advanced pressure switches and sensors, with excellent accuracy and reliability to meet the people's strong demand for economic and reliable wind energy. With timely delivery and cost-effective advantages.
The importance of hydraulic systems
In most turbines, the blades of a wind turbine are spaced at an angle to optimize output power at any given wind speed. Hydraulic systems have fewer components and are easier to maintain than mechanical systems, leading wind turbine manufacturers to adopt hydraulic pitch control.
Application
Hydraulic propeller control system
Yaw control
Hydraulic vane stop brake
The key role of sensors
Pressure sensors or pressure switches are used to monitor hydraulic pressure in accumulators and other areas.
The pressure switch provides a simple set value to ensure on-off safety
Pressure sensors provide precision predictive control
Hydraulic switches also play an important role in detecting the level of a hydraulic tank in most wind turbines. The corrosiveness of hydraulic oil requires the use of corrosion-resistant level switches. Doweston's variety of stainless steel and other materials of the level switch, can be reliable operation in hydraulic oil.
