More Information
Summary:The utility model relates to a sealing device for a water turbine. The utility model is characterized in that the position of a groove-shaped structure of a sealing seat of an important component of the sealing device is provided with fraction reducing material with the friction coefficient from 0.04 to 0.25. A rubber sealing ring can be rapidly started in the sealing seat and can be flexibly operated and moved, and therefore, the rubber sealing ring can be sealed and matched with a sealing rotary ring under constant pressure so that the rubber sealing ring is not easily worn and burned. The sealing device has the advantage of high operational reliability.
