The aim of the study is to reduce metal losses of structural elements of agricultural machines caused by atmospheric corrosion. The presents the theoretical justification and practical implementation of method of storing agricultural machinery in an open area under an active thermal cover. The object of research is the experimental design of an active heat-reflecting screen equipped with heating elements that provide an infrared radiation flux in the mid-wave range of the spectrum with a wavelength of λ = 5-20 μm. A design feature of the heat-reflecting screen is the location of heating elements relative to the agricultural machine in it. The protective effect is achieved due to the fact that when the probability of dew drops increases, the elements heating the internal surface of the heat-reflecting screen and the surface of the machine are automatically switched on, while the air, which is an optically transparent medium, does not heat up, which creates conditions excluding dew. During the tests, it was found that the use of an active heat-reflecting screen allows to ensure reliable safety of the protected machine. The possibility of local heating of the inner surface of the heat-reflecting screen and the surface of the machine without heating the entire volume of air space inside the storehouse can reduce the cost of electric energy. There is no need to preheat the airspace inside the store due to the fact that the thermal effect from the heating elements is observed immediately after being switched on.

Introduction. Anticorrosion protection of agricultural machinery working elements is provided through using pneumatic application of thickened preservatives with heating. For this purpose, a wire coil is inserted inside the preservative-supply hose and connected to a current source. It is known that the wire thickness and the coil pitch affect the hydraulic resistance to fluid flow. However, it has not been established how the diameter of the coil insert and its heating affect the flow capacity of the flexible hose channel. The purpose of the research is to increase the capacity of a flexible hose with an electrical-heater coil. For this purpose, it is necessary to determine its geometric parameters minimizing the hydraulic resistance to the thickened preservative flow and reducing the energy consumption for heating the material in the hose. Materials and Methods. It is proposed to investigate two electrical-heater coils of the same length, but of different diameter, made of steel welding wire pieces of equal length. There was developed a stand to study the influence of the inserted coil parameters on the hose hydraulic resistance. The stand was used to determine pressure losses in hoses with coils and in smooth hoses when used engine oil and thickened preservative flow through them. The flow capacity of the hose with cold and heated coils was estimated. Results. The method of heating the preservative in the hose wall layer is justified. At the same time, its flow capacity increases one and a half times with less energy consumption (2.4 times) than when heating the preservative in the central part of the hose. Under laminar flow mode, the pressure loss in the hose is 2 times lower when the coil is equal to 0.85 of the hose channel diameter than when the coil is equal to 0.67 of the channel diameter. Discussion and Conclusion. The research found the rational way of placing the electrical coil near the heated hose channel wall. At low air temperature, the reduction of the thickened preservative viscosity by heating in the hose helps to decrease the pressure loss up to 50% and increase its flow capacity by 1.4‒2.0 times. The use of a electrical-heater coil in the hose with thickened preservative will minimize energy consumption when preserving equipment on open storage sites.
