Embodiment Construction

[0024] Now, embodiments in accordance with the present invention will be described in detail with reference to the accompanying drawings, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like components throughout.

[0025] Here, it should be noted that the following will take the automatic lubrication system for the yaw bearing as an example for description, but the automatic lubrication system and the control method disclosed in the present invention are also applicable to the pitch bearing and the main bearing.

[0026] like figure 1 As shown, the bearing automatic lubrication system according to the embodiment of the present invention may include a motor 1, an oil tank 2, a pump 3 and a controller. The motor 1 can be connected to the pump 3 for driving the pump 3 . The pump 3 can communicate with the outlet of the tank 2 through the output line 5 and can communicate with the lubrication point of the yaw bearing 7 thr...

Abstract

The invention provides an automatic bearing lubrication system and a control method for a wind generator set. The bearing automatic lubrication system includes a motor, an oil tank, a pump and a controller. The motor is used to drive the pump. The pump communicates with the outlet of the oil tank through the output pipeline and communicates with the lubrication point of the bearing that needs to be lubricated through the supply pipeline. The climatic zone in which the wind turbine is located and / or the current season determines the lubrication strategy used to lubricate the bearings. According to the automatic bearing lubrication system of the present invention, the lubrication strategy for lubricating the bearing can be determined according to the climate region where the wind turbine is located and / or the current season, which solves the problem that the amount of lubricating grease injected into the bearing is not equal to the demand. , thus preventing the bearing from running smoothly due to insufficient lubrication or waste due to excessive grease injection.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an automatic bearing lubrication system and a control method for a wind turbine generator set. Background technique [0002] Yaw bearings of wind turbines are usually equipped with automatic lubrication systems. The automatic lubrication system can add lubricating grease to the yaw bearing to reduce the friction and heat of the yaw bearing during the yaw process, so as to make the yaw process smoother. In addition, the automatic lubrication system can also lubricate the outer teeth of the yaw bearing to ensure better meshing between the small teeth of the yaw reducer and the outer teeth of the yaw bearing and reduce noise and noise during the yaw process. shock, thus making the yaw process smoother. [0003] However, the existing automatic lubrication system usually adopts the lubrication strategy of timing and quantitative grease, that is, the filling interval an...
