VORRICHTUNG ZUR VERKRUSTUNGSDETEKTION EINES AXIALVERDICHTERS.
摘要
A process and device for detecting fouling of an axial compressor by measuring of pressure fluctuations within at least one of the stages of said compressor in the region of the compressor housing by means of at least one pressure sensing device, deriving a frequency signal from the signals delivered from said pressure sensing device, checking whether each of said frequency signals comprises at least one characteristic peak in the region of a characteristic frequency assigned to one of said compressor stages, and deriving a fouling parameter from said frequency signal, which parameter depends on a peak parameter indicative of the form of said characteristic peak and indicating the status of fouling of the compressor.
