SELECTION OF TECHNOLOGY FOR LONG-TERM STORAGE OF AGRICULTURAL MACHINERY USING A COMPUTER PROGRAM

Abstract. The newly developed computer program "Calculation of the economic efficiency of the technology of preparation and application of anticorrosive materials for protection of agricultural machinery from corrosion" is presented in the paper. An example of the program use is consistently shown when comparing two technologies of long-term storage of machinery, including the preparation of preservative materials BBM and IBM, and their 2 options of equipment for application - using a pneumatic paint sprayer SO-19 and a portable sprayer PRK-1-2 (option 1), as well as spraying using spray guns RADEX RRP 20114 and FUBAG S750 (option 2). It is assumed that the preservative materials are prepared by the agro-industrial enterprise itself, since the necessary components and technical means are widely available. As a result of the program operation, it was revealed that the cost of preparing the same volumes of IBM is lower than the cost of BBM by 5.1 rubles / liter. The economic effect of preparing IBM was 1020 rubles / year. The costs of applying the preservative material using SO19 were 152.4 rubles/l, while using the PRK-1-2 sprayer they were 89.4 rubles/l. The economic effect of replacing SO-19 when applying the preservative material with the PRK-1-2 was 11,334.2 rubles/year. The total economic effect of using the IBM material and spraying using the PRK-1-2 was 12,354.2 rubles/year. For the second version of equipment for applying preservative materials, the application costs were 191.2 rubles/l for RADEX RRP 20114 and 168.1 rubles/l for FUBAG S750, therefore, the FUBAG S750 spray gun turned out to be more economical and the economic effect of application with it was 4165.1 rubles/year, the effect of using IBM material and the FUBAG S750 spray gun was 5185.1 rubles/year.
