Knocking in centrifugal compressors

Knocking in centrifugal compressors refers to the phenomenon where pressure oscillations or vibrations occur, often due to irregular flow patterns or surge conditions. This can lead to performance degradation, increased wear, and potential damage to the compressor and associated system components. Proper design, operation within specified limits, and effective control strategies are essential to mitigate knocking and ensure reliable compressor performance. Monitoring parameters like pressure, temperature, and flow can help detect and prevent knocking incidents.
