WIPO Patent Application WO/2012/053389
Kind Code:
A1
Abstract:
[Problem] To provide a compressor equipped with a sealing system capable of suppressing the occurrence of failures arising from liquid infiltration of a dry gas seal and liquefaction of supplied sealing gas. [Solution} The sealing system is equipped with: a dry gas seal (15) having a rotating ring (16) positioned between a casing (1a) and a rotor shaft (11) and around the circumference of the rotor shaft (11), and stationary rings (19, 20) provided on the casing (1a) with elastic members (17, 18) interposed therebetween and so as to be capable of contacting the orthogonal edge surfaces of the rotating ring (16) that are substantially orthogonal to the rotor shaft (11); a sealing gas channel (6) having one end connected to a discharge channel (5), the other end connected so as to connect to a space (37) between the casing (1a) and the outer perimeter surface (16a) of the rotating ring (16) in the dry gas seal (15), and having a sealing gas adjustment valve (8) provided therein; and a drain gas channel (26) having one end connected so as to connect to the space (37) via a through-hole (35) formed in the casing (1a) below the rotating ring (16), and the other end connected to an intake channel (3).
