Method for diagnosing machine fault by analyzing hydraulic fluid

摘要

Method for monitoring conditions within a plurality of machines that receive fluid from a common source includes providing a supply line extending from the common source to an inlet at each of the machines. A return line is also provided that extends from an outlet at each of the machines to the common source to return fluid from each of the machines to the common source. A particulate filter is provided at the outlet of each of the machines so that each of the particulate filters will capture the particulates that were added to the fluid in the particular one of the machines with which that filter is associated. The particulate filters are periodically examined to determine the buildup of particulates that were generated within that particular machine. The particulate build up indicates whether or not a machine is in need of repair.
