Diagnostic and prognostic method for detecting wear process of hydrostatic displacement unit by detection device, involves sequentially activating progressive wear of subsensors, and determining degree of wear based on activated subsensors

摘要

The diagnostic and prognostic method involves arranging the sensor in a wear area of a wear-critical component of a displacement unit, particularly hydrostatic axial piston machine (1), and detecting a change of state of the sensor, particularly a material removal of the sensor or a change of state in the vicinity of the sensor by the sensor. The subsensors of the sensor are arranged in different wear zones in the wear area. A sequentially progressive wear of different subsensors is activated, and the degree of wear is determined corresponding to the activated subsensors. An independent claim is included for a device for detecting wear process of a hydrostatic displacement unit.
