PERSPECTIVE DIRECTIONS OF RESTORATION OF LUBRICANTS FOR UNIT OF HIGH-ENERGY AGRICULTURAL MACHINERY

Abstract

The authors considered the possibilities of optimizing the promising direction of restoring lubricants for units and aggregates of energy-saturated agricultural machinery. (Research purpose) The research purpose is studying the methods and possibilities of optimizing the recovery of lubricants of agricultural machinery units and aggregates during maintenance. (Materials and methods) Studied promising areas of collection and recovery of lubricating oils in the farms of the agro-industrial complex of Russia. It was determined that the purification of used oils in order to restore its basic operational properties is carried out at specialized sites (points) organized at the facilities of the repair and maintenance base of large enterprises, as well as at maintenance stations, repair plants and other enterprises of the agro-industrial complex with large volumes of fresh consumption and collection of used oils. The regeneration of waste oils serves as one of the sources of replenishment of oil resources. (Results and discussion) It was shown that as a result of processing the waste material at the outlet, it is possible to obtain a purified oil base of the corresponding group containing a composition of additives suitable for use in secondary and auxiliary technological processes as flushing oils, hydraulic fluids, as well as for the lubrication of low-loaded equipment that does not impose high requirements for the quality and purity of lubricants and working fluids. (Conclusions) The operations performed to improve the quality of oils are as follows: washing of oils with subsequent purification from water, mechanical impurities, resinous substances, wear products, oxidation and thermal degradation, addition of active components of the additive composition.
