Universal application.Fan yaw brake is to realize braking by the friction between friction plate and brake disc, when wind direction becomes
During change, the cabin on pylon top starts yawing rotation, and now, hydraulic braking disk is in half release conditions, for cabin rotation is provided
The damping force of stabilization, prevent blower fan from unstable phenomenon occurring, it is ensured that cabin calms down rotation.At the end of driftage is to wind, hydraulic braking
Disk will be in total head state, it is ensured that the stability of cabin during wind-driven generator normal work, prevent cabin under high wind state with
Meaning is rotated, and causes, influence generating efficiency inaccurate to wind direction.
In fan yaw brake fluid system, the yaw with internal tooth is bolted to atop a tower, outer shroud with
Cabin seat is connected, and inner ring is connected with tower flanges.And there is certain gap between cabin and the floating bearing of tower connection, machine
After group operation a period of time, the gap can also increase accordingly.During cabin is by moving to static braking, due to braking
The motion of cylinder is asynchronous to produce relative tilt with cabin laod unbalance, pivoting support bearing inner ring and outer ring, in inclined mistake
Cheng Zhong, brake plunger produces tangential force effect, and larger friction causes brake to be shaken between piston and cylinder body, serious mill
The inner surface of damage or plucking checking cylinder, on the one hand can cause that the sealing between piston and cylinder barrel is destroyed, and produce the phenomenon of oil leak,
Pollution hosted environment, when checking cylinder oil leak is serious, brake will increase in abnormal operating state, fan operation risk
Plus；On the other hand can also cause that braking moment is unstable, fan yaw vibration is strengthened.Now, it has to which shutdown is repaired, and is led
Cause the decrease of power generation of wind field.
