Wind turbine rotary joints

Rotary Union, commonly known as “hydraulic slip ring” or “fluid rotary connector” in the wind power industry, is a core and critical component in the pitch system of wind turbines. Its main function is to achieve continuous and leak free transmission of fluid media such as high-pressure hydraulic oil, coolant, or compressed air between the engine compartment (stationary part) and the hub (rotating part), thereby driving blade angle adjustment to ensure optimal power generation efficiency and safe shutdown of the fan at different wind speeds

Product Features:
Supported by two wide and high-precision bearings, the operation is smooth and the bearings do not require maintenance for life;
High speed and high-pressure sealing structure, no contact wear of sealing rings, ensuring long-term trouble free operation of the product;
Lower rotational torque;
Adopting a special product structure, there is no frictional heat generated during high-speed operation;
The rotational torque is not affected by working pressure and temperature;
The working range of the speed is wide, and it can reach up to 6500 RPM at high speeds;
Drain hole design to prevent leakage to the external environment;
Being able to tailor products to meet the needs of customers;
