Abstract
PURPOSE: To prevent serging effectively by such a constitution as changing signals, automatically and by steps, produced on the line having a pressure regulator in accordance with change in the suction temperature of a centrifugal compressor, etc.
CONSTITUTION: A suction valve 4 is provided on the suction line 1 of a centrifugal compressor, etc., to be controlled with the output from the selector 5, which selects No. l air signal line 2a for constant wind-pressure control and No.2 air signal line 2b having a pressure regulator 6a to make the setting of the throttle's critical opening of the suction valve 4. In a device with such a constitution, at least one thermal switch 8 is equipped on the suction line 1 as well as another pressure regulator 6b with different setting value from the regulator 6a is provided parallelly to the regulator 6a and further electromagnetic valves 7a, 7b which are controlled so as to open and be shut when it is over and under the actuating temperature of the abovementioned thermal switch 8, respectively, are provided on the output sides of respective regulators.
