Pomen poznavanja dejanskega stanja hidravličnega olja kot osnova za strateška odločanja

Darko Lovrec (Author), Vito Tič (Author)

Abstract

Običajna hidravlična olja na mineralni osnovi in turbinska olja, katera se uporabljajo na strojih in napravah imajo različno dolgo uporabno dobo. Ta je odvisna od vrste različnih faktorjev: od pravilnega vzdrževanja in uporabljen vrste nadzora in aktivnosti in od skrbne izbire vrste olja. Mehanizmi staranja hidravličnih olj in pa vzroki, zakaj jih je potrebno zamenjati so sicer zelo dobro znani uporabnikom, manj poznano pa je dejstvo, da so med posameznimi vrstami olj velike razlike glede njihove vzdržljivosti, ko so le ta izpostavljena delovnim pogojem stroja. Vsako podaljšanje uporabne dobe hidravličnega ali turbinskega olja ponuja tako finančne kot okoljske prednosti, a predpostavlja poznavanje dejanskega stanja olja. Za namene ocene preostale uporabne dobe olja, je v prispevku predstavljena nova metoda za primerna za on-line nadzor stanja in za testiranje vzdržljivosti oz. oksidacijske odpornosti različnih hidravličnih olj. Rezultati takšnega testiranja uporabniku nudijo možnost strateškega odločanja pri postopku nabave najprimernejšega olja z dolgo uporabno dobo.

Secondary title:	ǂThe ǂimportance of hydraulic oil real-condition identification as a basis for strategical desicion-making
Secondary abstract:	Conventional mineral-based hydraulic oils and turbine oils used within energy plants and machines have different long servicelives. 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 lesserknown 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.
