摘要

PROBLEM TO BE SOLVED: To provide a dry gas sealing system for protecting sealing means.;SOLUTION: This multistage centrifugal compressor 100 comprises the primary dry gas sealing means 9 for preventing the leakage of operating gas from the inside, and the secondary dry gas sealing means 10 for backing up the primary dry gas sealing means. Between the primary dry gas sealing means and the secondary dry gas sealing means, a dry gas sealing line 12 is provided for guiding gas leaked from the primary and secondary dry gas sealing means to the outside. The gas sealing line has an orifice 43 and a check valve 45, and a buffer means 44 provided between the orifice and the check valve.;COPYRIGHT: (C)2007,JPO&INPIT
