Original Kurzfassung:
This paper presents a novel data-driven approach
to detecting broken reciprocating compressor valves that is
based on the idea that a broken valve will affect the shape of
the pressure-volume (pV) diagram. This effect can be observed
when the valves are closed. To avoid disturbances due to
the load control, we concentrate on the expansion phase,
linearized using the logarithmic pV diagram. The gradient of
the expansion phase serves as an indicator of the fault state of the valves. Since the gradient is also affected by the pressure conditions, they are used as an additional indicator. After feature extraction, classification is done using support vector machines. The performance of the method was validated by analyzing real-world measurement data. Our results show a
very high classification accuracy for varying compressor load
and pressure conditions.
