Application of high-speed hydraulic rotary joints in the wind power industry

High speed hydraulic rotary joints are widely used in the wind power industry. They mainly provide hydraulic power for the wind blades in the wind turbine, adjust the blades, and more effectively convert wind energy into kinetic energy. Wind power rotary joints have very high requirements for product quality, generally requiring a warranty of about 8 years and a service life of about 15 years. In order to better meet the needs of the wind power industry, SD Company has developed a super wear-resistant sealing material that continuously rubs the shaft and seal, with a service life of up to 10 years. It is a product used in high-end fields and is rarely used in industry

The high-speed hydraulic rotary joint used in wind power is made of 316 material, which can prevent corrosion, acid and alkali, etc. It is supported by special customized bearings internally to ensure high-speed rotation of the entire rotor. The end face is installed with O-ring docking to save equipment installation space. In addition, from a technical perspective, the installation method of O-ring docking is more effective in reducing the frictional resistance of the rotary joint, reducing friction and reducing wear, which is more conducive to the service life of the product. The stator department adopts SAE flange connection to make the product more stable in the equipment and will not leak due to loose threads. Because the fan is very high, the labor cost of climbing the fan is very high, so the quality requirements for the product are more strict. SD company will continue to develop new ones.
