Abstract
PURPOSE: To prevent a temperature rise of pressure oil and its early deterioration, by connecting the delivery side of an emergency seal oil pump to an air extracting tank through a relief valve and the suction side to the air extracting tank through a variable throttling device.
CONSTITUTION: The delivery side of an emergency seal pump 5 is connected to an air extracting tank 16 through a relief valve 9 and pipe line 15 simultaneously the suction side of the emergency seal pump 5 is connected to the air extracting tank 16 through a variable throttling device 21 and the pipe line 15. In this way, when pressure oil is fed to shaft sealed parts 2, 3 by the emergency seal pump 5, a surplus amount of oil delivered from the emergency seal oil pump 5 branches to the air extracting tank 16, variable throttling device 21 and the suction side of the emergency seal pump 5 through the relief valve 9, thus a temperature rise of pressure oil and its early deterioration can be prevented.
