  • Patent number: 11692628
    Abstract: A sealing device for a gas-liquid two-phase fluid medium under variable working conditions includes a rotating shaft and a housing, and a chamber formed by the housing is configured to accommodate the gas-liquid two-phase fluid medium. The sealing device further includes a labyrinth sealing mechanism and a fluid dynamic-pressure mechanical sealing mechanism with double end faces, where the labyrinth sealing mechanism and the fluid dynamic-pressure mechanical sealing mechanism with double end faces conduct mutual synergetic effect. Sealing buffer chambers are arranged between the labyrinth sealing mechanism and the fluid dynamic-pressure mechanical sealing mechanism; the fluid dynamic-pressure mechanical sealing mechanism is provided with stationary rings and movable rings, where the stationary rings and the movable rings oppositely abut against with each other.
