A type of sealing device used in high-speed rotation such as steam turbines. When a disk attached to a shaft rotates inside a case filled with water or other liquid, the liquid is pressed against the outer periphery of the case by centrifugal force, preventing the leakage of gas inside. Applicable when the pressure difference is not very large. Source : Heibonsha Encyclopedia About MyPedia Information |
