PROCESS FOR DETECTING FOULING OF AN AXIAL COMPRESSOR

摘要

A process and a device for detecting fouling of an axial compressor (10) by measuring the pressure fluctuations within at least one of the stages (12, 14) of the compressor (10) in the region of the compressor housing (24) by means of at least one pressure sensing device (32), deriving a frequency signal from the signals delivered from the pressure sensing device (32), checking whether each of the frequency signals comprises at least one characteristic peak (70) in the region of a characteristic frequency assigned to one of the compressor stages (12, 14), and deriving a fouling parameter from the frequency signal which depends on a peak parameter indicative of the form of the characteristic peak (70) and indicating the status of fouling of the compressor.
