Way of Increase in Term of Operation of Agricultural Machinery

Abstract

Agricultural machines engaged in crop production, are used in cycles, and short-term from mid-spring to mid-autumn, and the rest for long periods in storage. The article deals with improving the reliability and extending the service life of machinery and equipment for agricultural purposes. Improving the reliability of machines and equipment of agricultural purpose is achieved by preventing metal corrosion during the long storage and the term of use is performed by maintaining and controlling the temperature and humidity of air in a sealed shelter. To prevent condensation on the surface of the equipment and the shelter is encouraged to pursue their heating infrared radiators to a temperature above the temperature of formation of the dew point. Infrared emitters installed in the air gap between object technology and a domed cover, and connected with the control unit, having in its composition sensors monitoring temperature and humidity under the cover. The uniform distribution of infrared radiation over the surface of the object storage is provided by a symmetrical placement of the sources of infrared radiation, and used as a material of the cover of insulated material with high reflectivity. The proposed method of storage of machinery and equipment limits the heat transfer between the machine and the environment. Due to the fact that a protective cover can make the desired protective properties (reflectivity, conductivity, limiting convective heat transfer) is the effect of limiting the speed of heat transfer, which avoids extreme temperatures, under which condensation may form on the surface of agricultural machines. As a material of the protective cover you can use modern insulating materials.

The effect of titanium nanoparticles on the corrosive activity of de-icing agents

“…Average corrosion mass loss of steel 08 kp samples in 5 % aqueous solutions of sodium chloride, sodium chloride with the addition of 0.5 g/l PMB and TiO2 NPs in the amount of 5•10 -3 g/l. S, m 2 Corrosion weight loss of samples, g/m…”

“…The presence in the body structure of a large number of welds, slots, gaps, as well as hollow elements (spars, amplifiers, thresholds) creates favourable conditions for the occurrence and development of corrosion processes [2]. A special role in the destruction of the vehicle body, especially its bottom, belongs to aggressive road pollution and chemicals used as de-icing agents in the autumn-winter period of road operation [3,4].…”
