Abstract

PURPOSE: To allow a runner of a machine to be raced for a long time, by providing a drainage pipe downward from the depressed water level, draining the water to the downstream with a drainage pump and preventing a temperature rise of the runner.
CONSTITUTION: When hot water on the top layer of a depressed water level 12 is discharged from a drainage pipe 7, a part of compressed air is simultaneously discharged and the depressed water level 12 rises. When it reaches an upper limit water level 12b, detection contact 13b is closed to permit a controller 14 to close a control valve 9, stop a drainage pump 8, open a feed air valve 11 and pour the compressed air. And when the water reaches a lower limit water level 12a, a detection contact 13a is opened to permit the controller 14 to open the feed air valve 11 and operate the drainage pump 8. The repetition of said operation suppresses a temperature rise in a draft tube 6, thus to perform an operation in air like condenser operation for a long time.
