The Importance of Hydraulic Oil Real-Condition Identification as a Basis for Strategical Desicion-Making
KOMUNALNA ENERGETIKA / POWER ENGINERING, 127
Conventional mineral-based hydraulic oils and turbine oils used within energy plants and machines have different long service-lives. This depends on variety of different factors: by proper maintenance, monitoring activities and strategies, and by careful selection of oil-type. Aging mechanism of hydraulic oils and the fact why they need to be replaced are well-known to the user, but lesser-known is the fact that there are great differences in the durability of hydraulic oils when exposed to machine-operating conditions. Any extensions in the service-lifetimes of hydraulic or turbine oils can deliver both, cost savings and environmental benefits, but requires the knowledge of real oil-condition. In order to evaluate the service-life of oil, this paper proposes a novel method appropriate for on-line condition monitoring and testing the durability and oxidation stabilities of different hydraulic oils. The test results can be used for selecting the more adequate oil with a long service-lifetime.
