On-line condition monitoring and evaluation of remaining useful lifetimes for mineral hydraulic and turbine oilsTič, Vito (Avtor) Lovrec, Darko (Avtor) Hydraulic and turbine oilsdegradation mechanismson-line condition monitoringtest methodsremaining useful lifetimeCondition monitoring of hydraulic and turbine oils, and especially their remaining useful life, is becoming an important strategic business advantage for plant owners, which benefits in environment protection and cost reduction. This monograph discusses the problem of condition monitoring of hydraulic fluids throughout their life-cycles. Particular emphasis is placed on assessing mineral-based oils’ conditions and their remaining useful lifetimes quantitatively. Practicality and usefulness are vital when developing and deploying various methods for condition monitoring systems within industrial environments. Therefore, it is important to know the oil degradation mechanisms and influencing factors, commonly used laboratory methods and oil ageing tests, as well as, for on-line condition monitoring system design, the available sensors with all their characteristics and restrictions. The proposed approach is based on a novel method for testing the durability and oxidation stability of different hydraulic and turbine oils. The developed mathematical model is based on data from previously conducted oil-ageing tests for the assessment of an oil's condition and its remaining useful lifetime. The method can also be used for comparison of different oils and selection of a more adequate oil with high oxidation stability and long service-lifetime.University of Maribor Press20172017-12-22 08:56:55Znanstveno delo69312ISBN: 978-961-286-130-8UDK: 661.177:543.383.2COBISS_ID: 93719809DOI: 10.18690/978-961-286-130-8NUK URN: URN:SI:UM:DK:EBGPRPBWslUniversity of Maribor Press
