TLDR
In this article, a system and method for predicting impending pump failure in a hydraulic system is disclosed, which measures and compares the running and moving volumetric deficiencies of the hydraulic system as a whole and if they are not within range of each other by a predetermined threshold, the system determines that at least one of the pumps in the system is about to fail.Abstract:
A system and method for predicting impending pump failure in a hydraulic system is disclosed. The system measures and compares the running and moving volumetric deficiencies of the hydraulic system as a whole and if they are not within range of each other by a predetermined threshold, the system determines that at least one of the pumps in the system is about to fail. If such a determination is made by the system, the pump displacement is at standby of each pump is then calculated and the pump with the greatest displacement at standby is determined to be the pump approaching failure. Once the pump approaching failure is identified, a signal is generated to apprise the operator or other entity to enable corrective action to be taken.read more

TL;DR: In this article, the authors proposed a method to automatically detect a failure in a machine based on the history data of the operation of the machine, and to decide whether or not to send to the monitoring station the sequential values of the operating parameters (e.g., engine rotational speed, lever operating position, vehicle speed, and tractive force) from within a prescribed period of time (from 10 min. before to 5 min. after) around the point in time t0 at which the fault was detected.
