Embodiment Construction

[0084] Figure 1 to Figure 6 Shows the sealed centrifugal turbo compressor 2 according to the first embodiment of the present invention, particularly a two-stage sealed centrifugal turbo compressor.

[0085] The centrifugal turbo compressor 2 includes a sealed housing 3 including an impeller housing part 3.1, a bearing housing part 3.2, and a motor housing part 3.3. Such as image 3 As shown more clearly in, the impeller housing portion 3.1 and the bearing housing portion 3.2 respectively include a cylindrical impeller housing 4 and a cylindrical bearing housing 5 that extend coaxially. The impeller housing part 3.1 and the bearing housing part 3.2 are fixed to each other, for example by screwing or welding.

[0086] The centrifugal turbocompressor 2 also includes a drive shaft 6 arranged in the sealed housing 3 in a rotatable manner and extending along the longitudinal axis A. The drive shaft 6 includes a first axial end 7, a second axial end 8 opposite to the first axial end 7,...

Abstract

The invention discloses a centrifugal turbo-compressor (2) which includes a hermetic casing (3); a drive shaft (6) having a longitudinal axis and rotatably arranged within the hermetic casing (3); a compression stage including an impeller (17) connected to the drive shaft (6); a gas suction inlet (42); and a gas flow path (P) fluidly connected to the gas suction inlet (42) and configured to supplythe compression stage with a gas flow. The gas flow path (P) includes a relaxation chamber (46) at least partially surrounding the drive shaft (6), the gas suction inlet (42) emerging substantially radially into the relaxation chamber (46); and a plurality of inlet flow guide channels (51) fluidly connected to the relaxation chamber (46) and angularly distributed around the longitudinal axis of the drive shaft (6), the inlet flow guide channels (51) extending radially towards the drive shaft (6) and being axially offset from the gas suction inlet (42) and the relaxation chamber (46).

Description

Technical field [0001] The invention relates to a centrifugal turbo compressor. Background technique [0002] As we all know, the two-stage centrifugal turbo compressor especially includes: [0003] -Sealed housing, [0004] -A drive shaft which is rotatably arranged in the sealed housing and extends along the longitudinal axis, [0005] -A first impeller and a second impeller, the first impeller and the second impeller are connected to the drive shaft, the first impeller and the second impeller are arranged in a back-to-back configuration, [0006] -A gas suction inlet which extends tangentially with respect to the longitudinal axis of the drive shaft, and [0007] -An inlet distributor configured to supply air flow to the first impeller, the inlet distributor has an annular disc shape and surrounds the drive shaft, the inlet distributor includes an inlet guide member that drives around The longitudinal axis of the shaft is angularly distributed and partially defines an inlet guide pa...
