Wind turbine spindle bearing lubrication management requires special attention

Wind turbine spindle bearings are one of the core spare parts of wind turbines, and their life is related to the life of the entire wind turbine, and once it fails, it is very difficult to replace and expensive
.
Therefore, the lubrication management of wind turbine spindle bearings requires special attention
.

Relevant people from the German company Baker said that the lubrication effect of the wind turbine spindle bearing is very important
for its life.
At present, there are two main lubrication methods for wind turbine spindle bearings on the market: grease lubrication and lubricating oil lubrication, of which grease lubrication accounts for a large
proportion.

Improper disposal of waste grease can cause great harm
to fan systems such as spindle bearings.
The passive waste oil collection method of the ordinary oil collection bottle used in the traditional lubrication system often cannot effectively collect the waste grease, and the waste grease that cannot be discharged in the bearing is easy to deposit, block, expand and leak the oil seal and overflow, which not only leads to the new grease can not be smoothly injected into the lubrication part for effective lubrication work, but also seriously pollutes the wind turbine and even the entire wind farm
.
At the same time, it will also worsen the bearing lubrication environment, increase friction torque, reduce wind energy utilization efficiency, aggravate bearing wear, especially the damage of spindle bearings and generator bearings, will seriously heat, cause the vibration of the whole machine to intensify, the life of the whole machine is sharply reduced, and finally lead to bearing seizure
.

He Shizhong, an expert from Guangzhou Institute of Mechanical Science, believes that in the whole life process of wind power equipment operation, safety and economic benefits should be taken as the core, and modern lubrication concepts and technologies should be used as the basis to ensure the equipment lubrication level of
wind farms.
This involves lubrication management, lubrication implementation, lubrication technology, lubrication efficiency and many other aspects
.

He Shizhong said that the cooperation between Guangzhou Institute of Mechanical Science and many enterprises is that the lubrication management has entered when the plant has not yet been put into production, and participates in the whole life process of the equipment to help the company formulate lubrication plans, including when to change the oil, how large the size of the particles is allowed, waste oil recovery and regeneration, etc
.

He Shizhong and his organization have been actively promoting the lubrication health management of enterprises, and are committed to establishing a system and standard thinking, formulating relevant lubrication management systems and technical standards, so that enterprise lubrication management has a basis to follow
.
In his view, it is necessary to evaluate the lubrication status of the wind farm, such as how the lubrication technology is adopted, what oil is used, where is the basis, how the lubrication method is, how the hydraulic system is changed and so on
.
Then the lubrication effect is evaluated, and the lubrication management system
of wind power equipment recognized by the industry is gradually formulated and improved.
