Abstract:
1. A method for increasing the absorption capacity in a multistage compressor, the compressor comprising rotor blades of a first compressor rotor blade row with a defined blade leaf profile, the rotor blades having a fixed blade angle in a flow direction, and blades of at least one further blade row arranged downstream of a second compressor stage having a defined blade leaf profile and, in the flow direction, a fixed blade angle, substantially identical to the blade angle of the first compressor rotor blade row, the compressor rotor blade row and at the least one further blade row arranged downstream of the second stage, are exchanged with different blade rows that include unchanged blade leaf profiles, and operate with a different blade angle, as compared with the fixed blade angles, and the blade angles of the at least one further blade row are selected as a function of the blade angle, modified for a greater absorption capacity, of the first compressor rotor blade row.
