Abstract
The invention relates to a method for automatically monitoring the performance of industrial equipment comprising a compressor. According to the inventive method, operating parameters of said 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, are 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. The invention can be applied to the production of gas from air.

11. A method which may be used for automatically monitoring the performance of industrial equipment, during the operation of said equipment, comprising the steps of:
-
a) measuring the operating parameters of said equipment with a measurement means, wherein said operating parameters comprise;
1) the flow rate of a gas through said equipment;
2) the pressure of said gas entering said equipment;
3) the pressure of said gas exiting said equipment;
4) the temperature of said gas entering said equipment; and
5) the temperature of a coolant for said equipment;
b) calculating, with a calculating means, a performance factor representative of the operation of said equipment, wherein said calculating means uses said measured operating parameters and a calculating rule stored in a storage means; and
c) indicating to a user, with an indicating means, performance monitoring information wherein said information comprises a function of said calculated performance factor. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
