Abstract

PURPOSE: To prevent the working fluid of a turbine from leaking into the atmosphere, by applying a double casing construction where a concentric inner casing with a horizontally divided face is concentrically fixed to the inside of an outer casing.
CONSTITUTION: In an outer casing 1 without a horizontally divided face, a shaft sealing device constructed by labyrinth fins 8b and a mechanical seal mating ring 8c, journal bearing 6a and a bearing mount 6 with a thrust bearing 7 for one end of a shaft of a rotor 3 are provided. While to the vertical end part of low pressure in said outer casing 1, an exhaust casing 5 having a shaft sealing device and bearing mount 6' for the shaft of the rotor 3 at the opposite end to the before said end is jointed. Further in said outer casing, an inner casing 2 with a horizontally divided face is concentrically fixed to the outer casing 1 at its end. A gap portion 2b between the inner casing 2 and the outer casing 1 is linked to the ambience of exhaust vacuum of a turbine and kept in vacuum.
