| Summary: | The study aims to substantiate the parameters and operating mode of the oil purification device from oxidation products to improve the efficiency of the use of lubricants. The methods of mathematical analysis and mathematical statistics, comparative comparison, generalization, and testing methods of agricultural machinery are used in the research process. It is established that engine oils are intensively polluted by oxidation products during processing, thereby accelerating the friction process due to the overload of tractor engines. During the performance of agricultural work in the oil composition, the content of oxidation products in the form of carbon, carbon dioxide, and asphalt products increases by 1.2%. Analytical coupling dependences for the process of cleaning motor oils from oxidizing products are obtained, and the dependence of the cleaning efficiency on the device parameters is established. The developed device consists of a container for collecting oils, a steam generator, a container for a sump mixer, a separate container for pure and sedimentary oils, and a vessel for re-collecting acetone. An installation has been developed to implement the technology of collecting and renewing oils in the conditions of the farm. In this case, the amount of contamination and the composition of oils is determined, and the operating mode of the device is selected for their resumption.
