Sunflower oil is an indispensable product of functional purpose, which at its reasonable consumption increases immunity, cleanses the body of toxins, improves the brain and heart, and as a result, having a complex effect on the whole body provides an undeniable benefit to human health. Modern development of sunflower oil purification technologies involves improvement of existing and development of new methods and technical means, environmentally safe, accompanied by minimum energy consumption and characterised by increased indicators of technological efficiency, providing the possibility of separation of unnecessary impurities and preservation of valuable components extracted from the oil for their further use. Such a promising method is the purification of sunflower oil in the electric field. The paper considers the possibility of cleaning sunflower oil by an electrostatic precipitator from suspended particles by means of an electric field acting on them. The planned experiment is described and the process of removal of unnecessary impurities is analysed. The justification of the factors and parameters of the experimental study is considered separately. The dependences of the electrical characteristics of oil on the parameters of the purification process are established. Analytical expressions for empirical dependences of energy parameters of the purification process, mode and parameters of ESP operation are determined. The adequacy of theoretical and experimental results has been checked. Having analysed the obtained results, the optimum parameters of effective cleaning and ESP operation were determined, which on the basis of the obtained regression equations should be the following: voltage at ESP electrodes U = 4.4 kV, interelectrode distance b = 0.01 m, oil temperature at the inlet θ = 42°С. The calculated energy consumption at these parameters is equal to 12 W-h/kg.

The article provides the analysis of the criteria for the sustainable functioning of the automobile operating company in emergency situations (ES), indicating the factors that most influence this process, and the main characteristics of the company, on which the degree of its stability depends. The assessment of the stability of the automobile operating company (AOC) objects is carried out by the two most common damaging factors of emergency situations in peacetime: shock wave and heat of detonation. Tables provide characteristics of the constituent elements of such a automobile operating company and the damage rate of the elements of automobile operating companies, which characterize the damage rate and the corresponding pressure resulting from the explosion. The graph of the dependence of the destruction probability of the main production factors on the stability indicators of the object elements is presented. The characteristics of the damage rate of buildings are also presented, which will make it possible to coordinate properly the work on the stability of the object. The sequence of assessing the stability of the automobile operating company is determined. Recommendations for ensuring the protection of enterprise equipment are given. Examples of protective screens for protecting equipment and the basics of the methodology for their calculations are proposed.Basing on the results of the analysis, the constructive solution for the protective structure for AOC enterprises is proposed, designed to reduce the impact of secondary damaging factors of emergency situations on the surrounding area.

The article is intended for engineering and technological workers involved in the exploitation of road transport, for specialists of automobile enterprises who are responsible for organizing road safety. Prevention of diseases and increase of efficiency of drivers, development of such functions as attention, speed of reaction, perception of space and other professionally important psycho-physiological qualities, can be achieved only through purposeful and dosed application of specially designed complex sports and health-improving classes. The article presents the simplified methodology for determining the physical condition of the personnel of the car enterprise in order to design exercises and complexes based on it to achieve the goal. It also offers forms of physical education, which contributes to the optimal method of their organization and conduct. In addition, the frequency of classes is of great importance, which directly affects the speed of recovery of drivers. The purpose of this article was to determine the content, organizational and methodological features of complex physical exercises for drivers of vehicles. In the course of the research, the comprehensive program was designed to prevent fatigue, prevent occupational diseases and improve the efficiency of drivers. The following forms of physical exercises were included in the complex program: introductory gymnastics, physical culture minute, physical culture pause, self-massage, corrective exercises for the eyes, physical culture and health classes.
