Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of lubricating system, in particular to a yaw lubrication control mechanism and system of wind turbine generator. BACKGROUND
[0002] The control strategy of the lubricating system of the wind turbine generator is generally based on time, and in the automatic control lubricating system, the lubricating system is automatically started to work for a fixed time when a fixed time interval is reached.

And for the patent document CN203363613U, in the process of using some lubricating systems, manual monitoring of the use of lubricating oil in the storage tank is required. Since the storage tank is often opened, it is easy to cause the lubricating oil in the tank to be oxidized and deteriorated. The cooperation between the storage tank, the electric lubricating pump, the main pipeline, the branch pipeline, the automatic controller, the liquid level detection sensor, the liquid level alarm, the safety valve, the first distributor, the second distributor and the distributor alarm device can effectively ensure accurate lubrication of each lubrication point and greatly improve the service life of the lubricating parts. The liquid level detection sensor and the liquid level alarm in the storage tank can accurately reflect the liquid level of the lubricating oil in time and remind timely refueling, reducing the oxidation of the lubricating oil by air and meeting the actual use requirements.
[0004] In the above-mentioned patent document CN203363613U, when the lubricating oil is transported and distributed, the electric lubricating pump transports the lubricating oil to the main pipeline, the main pipeline reaches the branch pipeline through the first distributor, and then the lubricating oil is distributed again through the second distributor. In actual work, the amount of lubricating oil in the main pipeline cannot be well controlled when it reaches the branch pipeline, that is, it is easy to cause excess or insufficient lubricating oil, which in turn causes waste of resources or insufficient lubrication. Especially when there is an excess, the lubricating oil will accumulate in the pipeline, which will easily reduce its quality and affect the working efficiency of the yaw lubrication system of the wind turbine generator, and further improvement and optimization are needed.
