Industry application overview
The wind power industry is under great pressure. It is necessary to improve the design of wind turbines, improve performance and reliability, reduce maintenance costs, and save costs per megawatt hour.
WTG operators must ensure that their equipment remains in operation for as long as possible. The performance and reliability of wind turbines are challenged because they often operate under harsh conditions (at sea, in cold or remote areas). At the same time, it also faces problems such as high maintenance costs and long delivery time of replacement parts, which will affect the competitive advantage of power generation. Therefore, it is important to adopt reliable components and intelligent processes. SKL has cooperated with leading original equipment manufacturers for many years to optimize the performance of wind turbines, improve the reliability and power generation of equipment. SKL's bearing, sealing, condition monitoring system and lubrication system help to achieve more cost-effective wind power generation and reduce lubricant consumption.
Typical customers in the industry
Vestas is a typical customer of SKL bearings in the wind energy industry. Stray current is one of the main threats to the generator bearing of Vestas variable speed wind turbine. If the current passes through the bearing, it may cause pitting corrosion and other types of surface damage. Finally, the bearing may fail - which may cause catastrophic failure of the generator itself. When the wind turbine fails, it cannot generate electricity and generate income. Most importantly, the repair of wind turbines will incur high costs. SKL bearings provide insulated bearings to reduce this risk. Insulated bearing is not conductive; On the contrary, it can prevent damage caused by electricity. This reduces the risk of generator failure and improves the reliability. Different degrees of insulation can be used to protect the bearings. At the most basic level, the surface ceramic coating helps to resist small current. For more severe service conditions, hybrid bearings with ceramic rollers can be used. This bearing has no conductivity and long service life.
