Abstract
Official abstract text for this publication.
A compressor arrangement has a common shaft, an axial compressor having at least a single-stage, and a radial compressor having at least single-stage. Assemblies of the, or each, axial compressor stage on the rotor side and assemblies of the, or each, radial compressor stage on the rotor side are attached to a common shaft ( 4 ). A ratio between a maximum diameter of the shaft ( 4 ) in the region of the axial compressor ( 2 ) and a minimum radial impeller seat diameter of the shaft ( 4 ) in the region of the radial compressor ( 3 ) is between 1.5 and 3.0.
First claim
Opening claim text (preview).
What is claimed is: 1. A compressor arrangement ( 1 ), comprising: an axial compressor ( 2 ) having at least one axial compressor stage; a radial compressor ( 3 ) having at least one radial compressor stage; and a common shaft ( 4 ) having a maximum diameter in a region of the axial compressor ( 2 ) and a minimum radial impeller seat diameter in a region of the radial compressor ( 3 ), wherein the axial compressor stage on a rotor side and the radial compressor stage on the rotor side are attached to the common shaft ( 4 ), and wherein a ratio between the maximum diameter of the shaft ( 4 ) in the region of the axial compressor ( 2 ) and the minimum radial impeller seat diameter of the shaft ( 4 ) in the region of the radial compressor ( 3 ) is between 1.5 and 3.0. 2. The compressor arrangement according to claim 1 , wherein the ratio between the maximum diameter of the shaft ( 4 ) in the region of the axial compressor ( 2 ) and the minimum radial impeller seat diameter of the shaft ( 4 ) in the region of the radial compressor ( 3 ) is between 1.8 and 3.0. 3. The compressor arrangement according to claim 2 , wherein the ratio between the maximum diameter of the shaft ( 4 ) in the region of the axial compressor ( 2 ) and the minimum radial impeller seat diameter of the shaft ( 4 ) in the region of the radial compressor ( 3 ) is between 2.0 and 3.0. 4. The compressor arrangement according to claim 2 , wherein the ratio between the maximum diameter of the shaft ( 4 ) in the region of the axial compressor ( 2 ) and the minimum radial impeller seat diameter of the shaft ( 4 ) in the region of the radial compressor ( 3 ) is between 1.8 and 2.5. 5. The compressor arrangement according to claim 2 , wherein the ratio between the maximum diameter of the shaft ( 4 ) in the region of the axial compressor ( 2 ) and the minimum radial impeller seat diameter of the shaft ( 4 ) in the region of the radial compressor ( 3 ) is between 2.0 and 2.5.
