Hydraulics for Wind Turbines

Learn to:

Use complex schematics as a troubleshooting tool
Verify the correct functioning of yaw, blade pitch and the rotor brake
Adjust critical pressure control valves
Develop a reliability based approach to system maintenance
Prepare a methodical troubleshooting "battle plan" in advance

Participants will study best maintenance practices and operational principles as they relate to the complex hydraulic systems that control wind turbines. This highly customizable course examines the circuits that govern blade pitch, rotor braking, and yaw.

The course begins with a review of hydraulic principles, and the function of major components and sub-circuits. Schematic reading is emphasized, as well as the need to create and maintain accurate system information. The critical valves, cylinder piston/rod seals, motor shaft seals, and the sensors that work together to make up a reliable system are covered in detail.

This course also features the Ten Step Troubleshooting Process. Students learn to create and follow a logical and efficient troubleshooting plan to deal with unexpected downtime.
