Abstract
A compressor includes a first impeller that compresses a gas, a second impeller that further compresses the gas and that directs the gas to a downstream region that is located downstream of the second impeller, an interstage passage that directs the gas from the first impeller to the second impeller, and a bypass passage that recirculates the gas from the downstream region of the second impeller to the interstage passage. The bypass passage has a downstream end that opens to the interstage passage to direct the recirculated gas into the interstage passage.
Claims20
A compressor comprising:
- a first impeller configured to compress a gas;
- a second impeller configured to further compress the gas compressed by the first impeller and to direct the gas to a downstream region that is located downstream of the second impeller in a flow direction of the gas;
- an interstage passage configured to direct the gas from the first impeller to the second impeller, wherein the gas is caused to swirl in a swirling direction that substantially corresponds to a circumferential direction of the interstage passage, when viewed from a transverse cross-section of the interstage passage;
- and
- a bypass passage configured to recirculate the gas from the downstream region of the second impeller to the interstage passage,
- wherein the bypass passage has a downstream end that opens to the interstage passage, and
- wherein the downstream end is oriented to direct the recirculated gas against the swirling direction of the gas in the transverse cross-section of the interstage passage.
