Abstract
PURPOSE: To lower the pressure on a gas side than the pressure on the back side of an impeller at a starting time and prevent ondesirable entry of oil, by arranging a solenoid switching valve which opens at a starting time and closes during steady running, on the way of a balancing piping connecting a mechanical seal side chamber to the intake side of a centrifugal impeller.
CONSTITUTION: A gas balancing pipe 17 is arranged from a mechanical seal side A to the intake side of a centrifugal impeller 4, and a solenoid switching valve 16 opening at a starting time and closing the time of steady running on the midway of the pipe 17. Thereby, the oil leaking through the mechanical seal 6 is restrained to enter the side of the centrifugal impeller 4, by lowering the pressure on a gas side A than the pressure on the back side of the centrifugal impeller 4 by the solenoid switching valve 16 opened at the time of starting a turbocompressor 3. As the result, vndesirable entry of oil occurring at starting can be prevented. On the other hand, during steady running, the mixing of oil mist in refrigerant gas through the balancing piping 17 is restrained, by making the solenoid switching valve 16 closed.
