Description
  • Power saws require a relatively large amount of oil for their operation the reason being idle lubrication of the cutting chain. Oil leakages in the environment can result in soil and water contamination and are known to impact both flora and fauna. Many countries in Europe struggle to minimize the damage by imposing the use of biologically degradable oils for these purposes. The work presents an assessment of these biologically degradable oils from the viewpoint of their possible occurrence in environment and from the viewpoint of their technical characteristics which affect reliability and economy of working with power saws. Oil dispersion is evaluated especially from the viewpoint of the concentration of its occurrence on the soil surface after cutting with the power saw. Technical properties evaluated include heat-oxidation stability and pumping properties of oils at low temperatures. There are original methods of measurement developed for these purposes, which facilitate high repeatability of res

  • Motorové pily potřebují ke svému provozu relativně velké množství oleje ke ztrátovému mazání řezacího řetězu. Úniky těchto olejů do okolního prostředí mohou znečišťovat půdu i vodu, mohou škodit flóře i fauně. Mnoho zemí, zejména v Evropě, se snaží tyto škody minimalizovat tím, že ukládají používat pro tyto účely pouze biologicky odbouratelné oleje. předkládaný příspěvek hodnotí tyto biologicky odbouratelné oleje z hlediska možností jejich výskytu v prostředí a z hlediska jejich technických vlastností, ovlivňujících spolehlivost a ekonomičnost práce motorových pil. Rozptyl oleje je hodnocen zejména z hlediska koncentrace jeho výskytu na půdním povrchu po řezání s motorovou pilou. Z technických vlastností byly hodnoceny zejména tepelně-oxidační stabilita a čerpatelnost olejů za nízkých teplot. Pro tyto účely byly vyvinuty originální metody měření, umožňující vysokou opakovatelnost výsledků. Cílem těchto snah je zajistit, aby oleje méně zatěžující přírodní prostředí měly klíčové technické parametry ales (cs)
