Certification standards

ISO 9001 and ISO 14001 are certification standards. ISO 9001 ensures that manufacturers meet quality management requirements when designing, producing and delivering shaft seals for wind turbines.

ISO 14001 ensures that manufacturers take environmental protection measures during the production process to reduce environmental impact.

IEC 61400 is a global wind energy industry standard, covering all aspects of wind turbines, including performance requirements and shaft seal design.

There are also several ASTM standards relating to rubber material and seal performance, including ASTM D2000 and ASTM D1418. These guidelines can assess the physical characteristics and effectiveness of materials used to seal wind turbine shafts.

NORSOK criteria: NORSOK pertains to the Norwegian oil production sector, and contains various prerequisites and accreditation benchmarks suitable for offshore wind turbines.

Introduce

The wind turbine shaft seal is integral to the wind turbine's power generation system. It seals the space between the turbine shaft and the generator to prevent leaks of lubricating or hydraulic oil and impurities from entering the equipment. Choosing the right seal design and type is significant for the turbine's performance. Correct shaft seal design can cut down on energy losses, prolong lubricant life, and diminish the need for maintenance and downtime. Furthermore, frequent examination and upkeep of shaft seals are critical procedures to guarantee wind turbines' smooth operation.

advantage

Wind turbine shaft seals are important for keeping the turbine efficient and long-lasting. They keep the turbine separate, stop dirt from getting inside, and stop the bearings and lubrication systems from wearing and corroding. With the ability to seal quickly at high speeds, they run continuously in high-speed conditions, ensuring they can work for 2-5 years. They also have a self-lubricating design, so external grease isn't needed, making them reliable in operation. The seal can resist corrosion well and thus, it is appropriate for salty marine environments. Its primary purpose is to stop grease from leaking out of the bearing cavity, safeguard the bearings from damage and deterioration, decrease the amount of friction, and increase the lifespan and dependability of the turbine. Furthermore, this results in lower maintenance expenditures and better power generation performance.
