The article discusses a way to increase the efficiency of automobile operation by improving methods for ensuring the operability of electrical equipment based on the diagnosis of generators by output voltage. As a diagnosis, it is proposed to perform a spectral analysis of the generated voltage in idle mode and to determine the state of various generator elements from the results. The effectiveness of the proposed solutions is determined by the non-separable diagnostics of the generator, which, based on a thorough examination, can determine the state of various elements of the generator. This method does not require taking the generator out of operation, does not depend on its design and can be used in difficult operating conditions to obtain preliminary information about the state of the generator at the initial stage of maintenance.

This article discusses some of the practical application of cavitation technologies in autonomous heating systems, attached elementary economic calculation. The modern achievements and cavitation vortex heat generators, principle of operation and types of such equipment. Marked positive and negative aspects of installation and operation of heat generators. A comparative analysis of the economic calculation of seasonal operating costs of the vortex heater as auxiliary heating systems and district heating tariffs for Pavlodar.

Different diagrams of thermal pumps operation at thermal power plants are considered in the article. Thus, installation diagrams are considered for thermal pump based on the use of low -grade heat of turbo-unit lubricating system oil and blow-down water of a steam generator.

One of the agent modern tasks is to ensure the cleanliness of the air basin. To ensure this, it is necessary to clean the combustion products of the fuel removed from the boilers after their cooling into the atmosphere from harmful substances, including nitrogen oxide.

Main problem: In the 18th century, when industrial production began, the use of steam and mechanized production caused major changes in the economy. As a result, production costs decreased along with an increase in the quantity and quality of products. During this period, production underwent a revolutionary transition from manual labor to mechanization. The potential impact of Industry 4.0 on labor markets remains an under-explored scientific field. It is estimated that Industry 4.0 will lead to unemployment by changing the employment structure and will bring new structural problems in terms of unemployment and labor relations. Purpose: The purpose of the study was to establish the impact of Industry 4.0 on the labor market and identify the consequences of the impact. Methods: studied, the evolution of production development, when mass production with electricity led to the Age of Industry 2.0, and then the emergence of the digital revolution, the use of electronics and information technology in production processes, marked the beginning of the Age of Industry 3.0. It is expected, according to international experts, scientists, that automation and robotic production will have a serious impact on the unskilled workforce and cause a critical reduction in the labor force of vulnerable sectors of society, that is, women, migrants, youth and the elderly. Results and their significance: This study assessed the possible impact of the fourth industrial revolution on labor markets. Through a literature review and analysis of emerging trends in Industry 4.0, the risks, opportunities and challenges of the process are explored in a comparative perspective. It has been established that countries must correctly perceive the transformation of labor markets and take appropriate measures. Otherwise, the applied labor-based low-cost industrialization model will lose its comparative advantage

The article is devoted to the study of the main types of retort packaging, as well as polymer and combined materials used for its manufacture. The authors have compiled a classification of retort packaging presented on the modern market, investigated the technological properties of packaging materials, and also determined the requirements for modern retort packaging: resistance to sterilization at a temperature of at least 120°C, steam and moisture resistance, chemical inertia to canned products, tightness, low gas permeability. It has been established that in order to give the retort packaging the required properties, it is made of multilayer polymer or combined materials, each of the layers of which performs certain functions. It is determined that due to the barrier properties of polymer and combined materials with respect to oxygen, retort packaging provides shelf life of canned products up to 5 years, which allows the use of retort packaging made of polymer and combined materials as an alternative to glass and metal packaging. In experimental studies, the composition of the outer layers of modern retort packaging was analyzed and it was concluded that polypropylene or polyethylene terephthalate are most often used, since these polymer materials are thermally and chemically resistant, vapor- and moisture-proof. It is established that materials that are barriers to gases are used as the middle layer – aluminum foil, metallized films, ethylene vinyl alcohol, polyamide. It is proved that polymer co-extrusion, multilayer injection molding or lamination is used for the manufacture of such materials and packaging. The data obtained indicate the high barrier properties of combined packaging materials, therefore, the thermal and chemical stability of the polymer and combined materials used makes it possible to use retort packaging for packing almost all groups of canned products.
