SYSTEM FOR HYDRAULIC PUMP HEALTH MONITORING
First Claim
1. A method of determining health of a hydraulic pump of a machine, the method comprising:
- receiving, by an electronic control module of the machine and from a first sensor of the machine, information regarding a pressure of a fluid of a hydraulic pump of the machine;
receiving, by the electronic control module and from a second sensor of the machine, information regarding a temperature of the fluid;
determining, by the electronic control module, a flow of the fluid based on the information regarding the pressure and the information regarding the temperature;
determining, by the electronic control module, a portion of the flow of the fluid that is directed to a particle counter of the machine;
receiving, by the electronic control module and from the particle counter, information regarding particles in the portion of the flow of the fluid;
determining, by the electronic control module, a quality of the fluid based on the information regarding the particles in the portion of the flow of the fluid;
determining, by the electronic control module, whether the flow of the fluid exceeds a flow threshold or whether the quality of the fluid is less than a quality threshold to determine the health of the hydraulic pump; and
taking, by the electronic control module, a remedial action when at least one of the flow of the fluid exceeds the flow threshold or the quality of the fluid is less than the quality threshold.

Abstract
A system may comprise a first sensor; a second sensor; and an electronic control module. The electronic control module may be configured to determine a flow of the fluid based on information regarding the pressure from the first sensor and information regarding the temperature from the second sensor; determine a portion of the flow of the fluid that is directed to a particle counter of the machine; receive, from the particle counter, information identifying a quantity of particles in the portion of the flow of the fluid; determine a quality of the fluid based on the quantity of particles; determine whether the flow of the fluid exceeds a flow threshold or whether the quality of the fluid is less than a quality threshold; and take a remedial action when the flow of the fluid exceeds the flow threshold or the quality of the fluid is less than the quality threshold.
