Abstract:

The study is devoted to the determination of the technological parameters of roller squeezing machines; these parameters determine the efficiency of the process, product quality, and the environmental situation of production. A mathematical model for the distribution of hydraulic force in roller machines has been obtained. The formulas for calculating the removed and residual moisture of the processed material are determined. It was found that the value of residual moisture depends on the value of the angle where the moisture changes position.

Abstract:

The sintering intensity is an important factor determining techno-economic efficiency of sinter production which provides the blast-furnace process with the main type of agglomerated iron ore raw materials. The charge sintering rate depends on technological parameters of the sintering process. Therefore, a systematic study of sintering technological parameters, which determine its intensity, is of practical and scientific interest. Indicators of the sintering process intensity are considered that assess it from both the mechanical and heat engineering positions. It is shown that in its purest form the sintering process intensity is characterized by the vertical agglomeration rate and combustion intensity of the sintering charge carbon. Two other indexes − the specific productivity for suitable sinter and intensity of heat output in the combustion zone – are less representative for the comparative estimation of sintering intensity, since their values depend on sintered mass strength and thermal effect of carbon combustion respectively. These factors go beyond the essence of the sintering intensity concept. Since content of fines of 5 – 0 mm at different sinter plants is not equal, representative performance comparison of sintering process is possible only taking into account the total amount of fines generated throughout the agglomerate transport path from sinter machine to blast furnace or the results of testing the agglomerate strength in a drum. A comprehensive systematic classification of techniques has been developed to intensify the sintering process based on the material-component principle using four levels of separation – objects, directions, paths and methods in which each subsequent level concretizes and develops the previous one. Its value is universality, which makes it possible to apply a systematization and separation system for almost all already known and future methods of sintering process intensification.

Abstract:

Injection molding is one of the most extended polymer processing technologies. It enables the manufacture of final products, which do not require any further operations. The tools used for their production – the injection molds – are very complicated assemblies that are made using several technologies and materials. Delivery of polymer melts into the mold cavity is the most important stage of the injection molding process. The fluidity of polymers is affected by many parameters Inc. mold design. Evaluation of set of data obtained by experiments in which the testing conditions were widely changed shows that the quality of cavity surface and technological parameters (injection rate, injection pressure and gate size) has substantial influence on the length of flow.

Abstract:

Agricultural boom sprayers are equipped with injection sprayers of mainly foreign origin. The main parameters of the injection sprayers shown in the catalogs display the consumption characteristics in certain ranges without taking into account the design parameters.(Research purpose)Determination of the design and technological parameters of an injection sprayer for the introduction of pesticides.(Materials and methods)The injection sprayer belongs to the class of twophase liquidgas isothermal jet devices with the formation of an airgas mixture at the outlet. It has been established that the design model of the working process of an injection sprayer is based both on the laws of the conservation of mass, energy, momentum, as well as theoretical relationships in the form of equations describing twophase jet devices, and empirical relationships characterizing flow parameters, geometric transverse and longitudinal dimensions of the spray channels.(Results and discussion)The following analytical relationships have been obtained: the relative pressure difference generated by an injection sprayer and the volume injection coefficient for different surface area ratios of the working nozzle to the flow section of the sprayer; the ratio between the crosssectional area of the mixing chamber to the area of the working nozzle outlet and the injection ratio; relative pressure difference and the injection ratio; the ratio between the crosssectional area of the mixing chamber and the working nozzle and the relative pressure difference. The authors have determined a set of dimensionless pressure characteristics of the injection sprayer for different ratios between the crosssectional areas of the working nozzle and the mixing chamber. It has been established that the ratio between the cross sections of the mixing chamber area and the working nozzle area increases as the injection ratio increases. It has been shown that for each injection coefficient, there is an achievable relative pressure difference in the injection sprayer.(Conclusions)The authors have proposed the design equations that determine the characteristics of an injection sprayer and its main design parameters – the diameters of nozzle and mixing chambers. They have calculated the main dimensions of the sprayer for aerial topdressing by introducing working solutions of pesticides.

Geo Аssets Engineering, 2023, vol. 334, no. 6, рр.120-125. In Rus. Relevance. Hydraulic fracturing in production and injection wells is one of the effective method for enhancing oil recovery, involving low-permeability zones and interlayers in the development, a mechanism for a wider coverage of productive zones by waterflooding, which makes it possible to convert part of off-balance reserves into commercial ones. According to experts, the use of hydraulic fracturing can increase the oil and gas recovery factor by 10–15 %. Currently, most of the oil fields in the Perm Territory are at the final stage of development. These fields, as a rule, are characterized by non-draining zones with residual reserves and low well flow rates. Most of the remaining reserves of the fields are concentrated in low-permeability reservoirs with a high degree of heterogeneity and difficult fluid filtration. The increase in the productivity of wells of these production facilities is achieved through the use of various geological and technical measures. The main aim: to develop a methodology for predicting the oil production rate post-frac with parameters that influence more, taking into account geological and technological characteristics of the object. Objects: Kashirskiy and Podolskiy carbonate deposits on one of the Permian fields. Methods: correlation and regression analysis. Results. The hydraulic fracturing method is widely used to increase well productivity. Unfortunately, oil flow rates obtained in practice do not always correspond to preliminary calculations. Using the example of one of the fields in the Perm Territory, a method proposed that allows estimating the initial oil production rate after hydraulic fracturing using the values of the technological parameters of productive deposits and the methods of mathematical statistics. A good agreement between model and experimental results was obtained.

The main parameters of the contact curve of each roll are its shape and length, and the extent of the slip and no-slip zones. Analytical dependencies were obtained that determine the parameters of the contact curves of the rolls of technological machines. It was revealed that at the beginning of the contact zone the skin points are distant from the roll covering point, in the zone at the end of the contact zone it is ahead of it. At the end of the contact zone, the angle between the corresponding points of the skin layer and the roller coating is equal to the modulus of the difference between the lag and advance angles.

Abstract:

Overhaul with pipeline lifting is one of the most frequently used repair methods in pipeline system technical operation in the oil and gas industry. Using this repair method, the anti-corrosion protective outer coating that has lost its protective properties is replaced. If necessary, pipe walls are repaired. Organizations operating pipelines are equipped with modern methods and means for determining the technical condition of the protective coating and the pipes themselves. The technical operation system allows timely detection of defective sections and carrying out appropriate repairs, ensuring reliable and efficient pipeline operation. At the same time, the overhaul of the pipeline, especially with its lifting, is an important and complex technological process. Pipeline lifting leads to the appearance of additional stresses in the pipe walls, which were not taken into account at the pipeline design stage. These stresses are added to the stresses from the temperature difference and pressure in the pipe cavity of the pumped product. The total stresses, taking into account the actual technical condition of the operated pipelines, can reach significant values that affect the strength of the pipelines and the safety of the overhaul. At the same time, regulatory documents for pipeline technological parameters calculating do not take into account the forces and stresses in the pipe wall from the effects of temperature differences and pressure in the pipe cavity. In this regard, it is necessary to improve the existing pipeline technological parameters of the overhaul with lifting, taking into account all loads and impacts, as well as the strength of the pipes and the safety of the overhaul. In addition, in well-known calculations, the required lifting height of the pipeline at the place of installation of cleaning and insulating machines is not the initial parameter, which complicates the provision of the specified lifting height in order to create normal operating conditions for the machines. The purpose of the work is to ensure the strength of pipes and the safety of overhaul with lifting of the existing pipelines based on the improvement of the calculation of repair technological parameters. Improving the calculation includes taking into account the longitudinal forces acting in the pipeline when it is lifted and taking the required lifting height at the places of installation of cleaning and insulating machines as an initial parameter. Research methods - analysis and theoretical studies of the stress-strain state of the existing pipeline when it is lifted by pipe-laying machines. The dependences of the technological parameters of a overhaul with pipeline lifting on the longitudinal forces acting in the pipeline in the lifting section and lifting heights at the places of installation of machines for pipeline cleaning and insulating are obtained.

Abstract:

The article is devoted to determine the technological parameters of soil compaction by rollers according to soil properties in construction. The compaction of the soil occurs due to certain force loads on the soil. Nowadays, there are enough methods to determine the technological parameters of soil compaction process, however, there are few research methods that consider the system of soil-machine-technological parameters. The urgency of the soil compaction process, which ultimately determines the quality of construction products, was emphasized. The basic physical and mechanical properties of soil and technological parameters of the compaction process were given. Analysis of discrete mathematical model of interaction between roller and soil was carried out in order to determine the technological parameters of soil compaction process in the field of construction technologies. A rheological model to describe the soil properties was used. The differential equations of the interaction between roller and soil have been made. A numerical calculation method to solve the differential equations has been proposed. The basic technological parameters of soil compaction process by rollers have been determined - the thickness of soil layer to be compacted, the number of the roller passes, and the speed of the roller movement. The methodology of theoretical and experimental researches of interaction between roller and soil has been proposed in order to clarify the mathematical model and to find the technological parameters of the compaction process. Experimental research methods are based on the determination of the stress-strain state of soil and on the Fourier analysis of the experimental data. Fourier analysis of the experimental data makes it possible to analyze the qualitative energy spectrum of the interaction between roller and soil to determine the rational amplitude-frequency characteristics of the compaction process. Experimental studies allow obtaining such rheological properties of soil as elasticity, viscosity, coefficient of elastic resistance, etc. The main recommendations for the choice of compaction method depending on the type of soil have been proposed.

Abstract:

Annual harvesting of a large number of forest seeds allows for reforestation on the territory of the Russian Federation. Moreover, more than 70% falls on the seeds of coniferous trees. In order to increase their sowing quality and reduce losses, the seeds are dehumidified, cleaned, sorted by density and size, stratification, as well as other technological operations. The use of refined seeds during reforestation allows increasing the productivity of sowing units, improving the quality of seed placement, reducing the volume of seed bins, which leads to a decrease in the metal consumption of sewing machines as a whole. For experimental studies, special sieves were made: plastic with chamfered, plastic with standard holes and plastic with rounded edges. The dependences of the completeness of separation of the procode fraction ε were determined for various combinations of the angle of inclination α and the rotation frequency of the working body ω for various seed thicknesses. The angle of inclination of the working body α was changed from 4 ° to 12 °, in increments of 2 °, rotation frequency ω from 400 min--to 1200 min-¹, in increments of 200 min-¹. The size gap was set taking into account the dimensional characteristics of existing sieves with rectangular holes and was 0.2 mm. Studies were conducted on the seeds of common pine.

Abstract:

The aim of this study was to investigate the effect of blade type and sharpness angle on blade wear, cutting power, and surface roughness. The study was conducted on medium-density fibreboard (MDF) panels. Two blade types were analyzed (high-speed steel and cemented carbides) along with three variants of sharpness angles (40°, 45°, and 55°). Machining operations were performed on a spindle moulder at a feed rate of 6.3 m/min and rotational speed of 4500 min-1. The blade wear criterion was adopted as the loss of cutter surface area measured on the rake face. Roughness was determined using the Ra parameter, which was measured at three points on the cross-section of the MDF panel. A new, multifaceted approach to the study of cutting a narrow surface of the MDF board was used, thanks to which the interaction of such parameters as blade wear, cutting power, and machining quality as well as the type of material of the knives and their angular parameters were determined. An increase in blade wear and cutting power was recorded with an increase in cutting path, while roughness at the MDF panel cross-section varied. The cemented carbides cutter with the 45° angle may be proposed as optimal, because it showed a relatively low wear and cutting power while providing good quality of the milled surface.

Abstract:

The prospects for the use of a plant raw material – stevia as a natural sweetener for obtaining sweet extracts have been substantiated. Literary research has been conducted on the expediency of carrying out preparatory operations of stevia-raw material in order to intensify mass exchange processes during extraction; their necessity has been theoretically justified. A number of studies have been conducted with the aim of intensifying the process of extracting the dry mass of stevia leaves. Preliminary preparation of stevia was carried out – crushing (using a laboratory crusher – A1-DM2R) and subsequent sieving to the average size of the leaf fraction – 3.9±0.1 mm. It is proposed to use whey from the production of sour milk cheese to obtain sweet extracts of stevia for their further use in the food industry. It has been established, that the highest efficiency of the extraction process of the prepared dry stevia leaf mass is achieved with a hydromodule – 1:15. Carrying out the process under these conditions allows to achieve the highest degree of extraction of extractive substances – 29.9. The results of the experimental studies, obtained and presented in the article, can be used to carry out further physicochemical analyzes of the quality of the obtained stevia extracts and the possibility of combining them with a milk base to obtain a dietary range of food products

Abstract:

It may be well said that the most used indicator of the quality of any technical system is reliability. Basically, this indicator shows the probability of proper technical system functioning within certain time period and under given operating conditions. To ensure that a system under construction possesses adequate given pre-defined characteristics and reliability indicators, it is necessary to plan the reliability and apply suitable methods when new technical systems are developed. Road represents an elementary traffic subsystem, as well as a technical subsystem, constructed by the society in order to meet the communication needs. Its purpose is to enable traffic system functioning. If a road is seen as a system, one can observe the features determining the structure and the principal on which its function is based. The road functioning itself is characterized by a variety of features, the most important being the management characteristic and specific social interest, categorization structure, and roadway condition. To enable smooth and safe traffic, roads should be of prescribed technical and usage levels. Reference is made specifically to road maintenance in the Primorje-Gorski Kotar County. KEYWORDS: infrastructure, terotechnology, road network, maintenance, theory of benefit
