More Information
Summary:A self-lubricating sealing device for water turbines, which comprises a sealing revolving ring, a rubber sealing ring and a sealing seat, characterized in that the utility model applies a rubber sealing ring capable of self-lubricating, and cylindrical solid lubricating material, graphite pins, are arranged on the periphery of the rubber sealing ring. With help of the above characteristics, friction between the sealing revolving ring and the sealing ring are reduced to give more durability and high reliability to the sealing devices.
