The diagnostics of the gas compressor unit to forecast its residual life

Abstract

The modern diagnostic techniques make it possible to define the technical state of the compressor plant
equipment and its components (turbines, axial compressor, combustion chamber). The determination of the
compressor plant equipment technical state makes it possible to forecast the residual life of units during their
further operation.
The elements to be checked for the residual life have ceratin diagnostic parameters that are functions of operating
time. The forecast objective is to determine the critical (threshold) value of the compressor plant equipment
and define the operating time to the next repair. By applying the function of the parameter change, it is possible to
estimate the system residual life, that is, the equipment service life without worn parts to be replaced.
