Abstract

PURPOSE: To prevent seizure by supplying lubricating oil to a bearing by an oil pump with an oil sump provided in the bearing stand and connecting the rotor of a generator for supplying power to a hydraulic pump driving motor and the rotor of a steam turbine mutually by a hydraulic clutch at the time of drop of the lubricating oil pressure.
CONSTITUTION: The rotor of a generator 24 is connected to the rotor 1 of a steam turbine through a hydraulic clutch 25 and a branching oil supply pipe 13a branching from an oil supply pipe 13 is connected to the hydraulic clutch 25, so that the lubricating oil pressure at the time of operation is applied. When the lubricating oil pressure is applied, the rotor of the generator 24 is disconnected from the rotor 1 of the steam turbine. When the lubricating oil pressure drops to a specified value or lower, both the rotors are connected together. Due to this constitution, the rotor 1 of the steam turbine and the rotor 6 of the generator are normally supplied with lubricating oil from an oil supply device 12. The, when the lubricating oil supply fails so that the lubricating oil pressure decreases, the clutch is actuated and so the generator 24 is operated, thereby driving a motor 21. Lubricating oil is thus supplied with an oil pump from an oil sump 20.
