Condition Monitoring of Wear Progress in Hydrostatic Pumps

This paper represents a practical methodology for monitoring the wear in the displacement elements in hydrostatic pumps. The technique is based on appropriate signal processing of the output pressure wave which reflects the geometrical changes in the internal parts. The geometry deviates in case of wear and the degree of deviation can be spatially analyzed to gain an indicator to the wear progress. The method is effective and computationally efficient in comparison to other algorithms, for ex. wavelet transformation. The design is followed by a successful experimental validation, for a case of internal gear pump IGP .
