Abstract
PURPOSE: To provide the reduced investment and easy maintenance due to compact design, by relocating a head tank at the lower position and to reduce the piping cost by cutting short the piping line.
CONSTITUTION: A feed oil pump 4 supplies seal oil for the shaft sealing element 3 of a compressor. Seal water runs through a supply pipe 5 and is fed to the bottom compartment 11a of a head tank 11 containing a diaphgram 12. Level detection liquid higher in specific gravity than the seal water is sealed in the middle compartment 11b of the head tank. Higher pressure gas is fed to the top compartment 11c of the tank through an inlet duct 8. An emergency tank 13 is communicated with the high-pressure gas inlet duct 8 by a solenoid valve 14. When the seal water supply system fails, the solenoid valve 14 is opened to supply working fluid for an emergency tank 13. The seal water is supplied for the seal element 3 to prevent an accident.
