Early Fault Detection in Reciprocating Compressor Valves by Means of Vibration and pV Diagram AnalysisLeaking valves are the most common reason for unexpected shutdowns of reciprocating compressors. Therefore, a leaking valve has to be detected early and reliable, even for arbitrary operating......

PROBLEM TO BE SOLVED: To prevent a variation in volume of a diaphragm due to deformation by independently providing an auxiliary pressing member which presses the diagram at a position different from the pressing member in a two-way valve in which the diaphragm is pressed against a valve port ...
pV diagramFeature extractionClassification2014, Springer-Verlag London. We present a novel approach to detecting leaking reciprocating compressor valves based on the idea that a leaking valve affects the shape of the pressure-volume diagram (pV diagram). This effect can be observed when the valves ...
The principle of valve fault diagnosis using indicator diagram is introduced. With a pressure transducer installed at the end of a channel which is embedded into the cylinder through the valve cover and valve, the pressure signal within the working chamber of a reciprocating ...
