MJNRHT STANDARD FOR MAINTENANCE OF AGRICULTURAL MACHINERY

Abstract

Revision of the GOST 20793-2009 "Tractors and agricultural machines. Maintenance" with the introduction of modern scientific achievements to increase the resource of machines is an urgent task. (Research purpose) The research purpose is outlining the main provisions of the GOST 20793 and analyzing the proposals of the members of the Interstate Council for Standardization, Metrology and Certification of the Commonwealth of Independent States. (Materials and methods) Authors used the methodology of developing standards at the interstate level. The specifics of this work consists in passing a public discussion and examination of the draft standard by specialists of the engineering service and interested organizations of the Russian Federation and the countries of the Commonwealth of Independent States, as well as in a detailed analysis of the recommendations received. (Results and discussion) Authors presented the final version of the draft standard corresponding to the current conditions of the state of the machine and tractor fleet and the engineering service of the agro-industrial complex based on the analysis of the received proposals and recommendations of interested organizations. Authors have prepared a draft for standard control and approval in Rosstandart. (Conclusions) The introduction of the modern GOST 20793 will contribute to improving the efficiency and increasing the service life of worn-out aggregates of agricultural machines, reducing the costs of their technical operation, as well as the technical progress of the domestic agro-industrial complex. The standard clarifies the types, frequency, rules of maintenance together with the current repair, recommends express control of lubricating oils, the use of built-in diagnostic systems, organoleptic diagnostics based on qualitative characteristics, as well as the introduction of repair and restoration tribocomposition machine units into engine and transmission oils. The implementation of the requirements of the standard will allow you to organize the work in the production and circulation of products and certification, increase the resource and efficiency of the machine and tractor fleet.
