COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/176486
Kind Code:
A1
Abstract:
With this compressor, a fluid compressed by a first impeller is further compressed with a second impeller. This compressor comprises: an impeller housing having a first housing that houses the first impeller and a second housing that houses the second impeller; and an interstage component that is coupled to the impeller housing and forms, together with the impeller housing, an interstage flow path for introducing fluid from the first impeller to the second impeller. The interstage flow path has at least one curved flow path. The curved flow path includes an inner peripheral side wall surface that curves on the inner peripheral side in a cross section through the centerline of the curved flow path, and an outer peripheral side wall surface that curves on the outer peripheral side in the cross section. One of the inner peripheral side wall surface and the outer peripheral side wall surface is formed on the impeller housing. The other wall surface is formed on the interstage component.
