  • Use of an on-line condition monitoring system for hydraulic machines
    Lovrec, Darko ; Tič, Vito
    On-line condition monitoring of the entire system or individual components can be used for detection of impending system break-down, at which point, on-line monitoring of the hydraulic fluid plays a ... decisive role in general on-line condition monitoring. Physical and chemical properties of hydraulic oil are changing during its use as a function of many influencing factors, such as increased temperature, friction, wear, water contamination, etc., which results in accelerated oil oxidation, thermal decomposition of the oil and the increased level of oil contamination (liquid or solid). To determine oil condition, paper presents various physical and chemical changes in hydraulic oil, which can be detected using robust and cost-effective on-line sensors. Understanding the mechanisms of oil ageing and deterioration is crucial, and it is not only necessary for proper interpretation of measured results and taking consequent actions, but it is also important for proper selection of individual sensors or entire condition monitoring system design. The use of on-line oil condition sensors together with appropriate knowledge of physicochemical changes in oil allows user to have constant overview of the oil quality and its properties. This information can sometimes be crucial to prevent damage and ensure reliable operation of the system.
