How to assess the remaining life of a hydraulic system? What are the key indicators?

2025-04-28

To evaluate the remaining life of a hydraulic system, multiple indicators need to be examined: Oil condition - Use oil analysis to detect changes in viscosity, acid value increase, and contamination to determine the remaining service life of the oil. Wear of key components - Measure the degree of decrease in the volumetric efficiency of the axial piston pump. Generally, if it is less than 80%, overhaul or replacement should be considered. Leakage - If the total leakage of the system exceeds twice that of a new machine, it indicates serious wear. Performance degradation - Compare the current pressure, flow, response speed and other parameters with the differences when the machine was new. Failure frequency - Count the number of failures per unit time. An upward trend indicates that the system has entered a wear and failure period. Economic analysis - Compare the maintenance cost with the replacement benefits. Consider updating when the annual maintenance cost exceeds 30% of the residual value of the equipment. Comprehensive evaluation methods include: regular and comprehensive testing to establish benchmark data; using condition monitoring technology to track key parameters; referring to the average service life of similar equipment; and considering new requirements for equipment due to changes in production processes.
