Method for adjusting gas-dynamic characteristics of centrifugal compressors taking into account changes in the technical condition of the flow path

On the example of several process units of the oil refinery, an analysis was made of the nature of changes in the gas dynamic characteristics of centrifugal compressors that occur as a result of wear (degradation) of the flow part under the influence of erosion, corrosion or chemical processes as a result of the interaction of the compressed gas with the elements of the flow part. A method has been developed for adapting (correcting) the gas-dynamic characteristics of centrifugal compressors based on the introduction of corrective functions with empirical coefficients that take into account the change in the actual state of the flow section.
