Abstract
In a method for operating a gas compressor which compresses gas whose supply conditions change and which is equipped with an intake-flow regulating mechanism, a limit pressure ratio that defines the operational upper limit of the pressure ratio relative to the intake flow rate of the gas compressor or the degree of opening of the intake-flow regulating mechanism to prevent surging in the gas compressor is corrected by multiplying a reference limit pressure ratio calculated from the design conditions of the gas compressor by a first correction factor calculated depending on a detected operating-state value of the gas compressor.

A method for operating a gas compressor which compresses gas whose supply conditions change and which is equipped with an intake-flow regulating mechanism,
- wherein a limit pressure ratio that defines an operational upper limit of a pressure ratio relative to an intake flow rate of the gas compressor or a degree of opening of the intake-flow regulating mechanism to prevent surging in the gas compressor is corrected by multiplying a reference limit pressure ratio calculated from design conditions of the gas compressor by a first correction factor calculated depending on a detected operating-state value of the gas compressor.
