Description
Die Erfindung betrifft ein Schmiermittel, welches sich insbesondere für die Anwendung in Luftkompressoren" eignet. Beim Kompressionsvorgang in einem Kolbcn- oder Kreiselverdichter wird die Luft erhitzt, und diese erhitzt dann ihrerseits das Schmieröl im Kompressor, z. B. durch direkten Kontakt mit dem öl. Wegen dieser kombinierten Einwirkung von Luft und Wärme muß das Schmieröl gegenüber dem Abbau durch chemische Umsetzungen widerstandsfähig sein, da sonst z. B. gummiartige Verbindungen entstehen können, die im Schmieröl enthaltene Feststoffe aller Art, wie Staub, binden können und an den ölbenetzten Oberflächen Rückstände, wie Lacke oder harter Kohlenstoff, gebildet werden können. Die Schmieröle müssen auch widerstandsfähig gegenüber der Emulsionsbildung mit Wasser sein, das mit dem Schmieröl in Berührung kommt, z. B. ausrinnendes Kühlwasser oder das in der zu komprimierenden Luft enthaltene Wasser. Eine Emulsionsbildung beeinträchtigt die Wirksamkeit des Schmieröls und die ölzirkulation. Emulsionen können ferner chemische, elektrochemische oder mechanische Korrosion bewirken. Die Zylinderwände können z. B. durch Wassertropfen angegriffen werden, und in Wasser gelöste Salze können durch das Schmiersystem transportiert werden und Metallteile angreifen.The invention relates to a lubricant which is particularly suitable for use in air compressors " suitable. During the compression process in a piston or centrifugal compressor, the air is heated, and so is it then, in turn, heats the lubricating oil in the compressor, e.g. B. through direct contact with the oil. Because of these Combined exposure to air and heat, the lubricating oil must resist chemical degradation Implementations be resistant, otherwise z. B. rubber-like compounds can arise in the All kinds of solids contained in lubricating oil, such as dust, can bind to and on the oil-wetted surfaces Residues such as paint or hard carbon can be formed. The lubricating oils must too be resistant to emulsification with water in contact with the lubricating oil comes, z. B. running out cooling water or the water contained in the air to be compressed. One Emulsification affects the effectiveness of the lubricating oil and the oil circulation. Emulsions can also cause chemical, electrochemical or mechanical corrosion. The cylinder walls can, for. B. can be attacked by water droplets, and salts dissolved in water can get through the lubrication system are transported and attack metal parts.
