Abstract (en)
[origin: WO2015043916A1] The invention relates to a turbo-machine, which can be operated in an optimized driving range. To this end, a method for operating a turbo-machine having at least one turbo-machine stage, which has at least one rotary shaft is disclosed. According to the method, the following method steps are carried out: a) determining a desired efficiency characteristic value ηsoll of the turbo-machine stage; b) determining an actual efficiency characteristic value ηist of the turbo-machine-stage; c) determining a comparison efficiency characteristic value of the turbo-machine stage by comparing the actual efficiency characteristic value ηist and the desired efficiency characteristic value ηsoll to one another; and d) changing at least one operating parameter of the turbo-machine stage subject to the comparison efficiency characteristic value ηvgl, wherein in order to determine the actual efficiency characteristic value ηist, a measuring of a torque of the rotary shaft of the turbo-machine-stage is carried out. The torque applied to the rotary shaft during the operation of the turbo-machine is measured. Preferably, the torque is measured in a magneto-elastic manner. The invention further relates to a turbo-machine comprising at least one turbo-machine stage, which is has at least one rotary shaft, wherein the turbo-machine has a device for carrying out the method. The turbo-machine is a turbo compressor, for example, which comprises a plurality of compressor stages (turbo-machine stages). Each of the compressor stages can be controlled separately.
