Zusammenfassung: | The utility model provides an ebonite cylinder sealing device for 300MW level vapour-cooled turbine generators, which is characterized in that the ebonite cylinder sealing device comprises an ebonite cylinder; an O-shaped sealing ring, a V-shaped sealing ring and a recessed V-shaped sealing ring which are mutually and tightly buckled are arranged in a gap between the ebonite cylinder and an end cover of the generator; and a press ring is arranged among the ebonite cylinder, the end cover of the generator and the recessed V-shaped sealing ring. The utility model has the advantages that the sealing problem between the stator of the vapour-cooled turbine generator and the ebonite cylinder can be solved, and the sealing effect is good. |
