System for monitoring the performance of industrial equipment, e.g. compressor used for the separation of oxygen from ambient air

摘要

The method involves, operating parameters of the industrial equipment, including at least the gas flow (Q) in the compressor, the pressure (Pin) of the gas entering the compressor, the pressure (Pout) of the gas leaving the compression, the temperature (TrEfr) of the coolant of the compressor, being measured. Automatic calibration subsequently occurs for a calculation rule in order to predict the performance factor and to detect a deterioration of the state of the industrial equipment.
