DEVELOPMENT OF NEW DESIGNS OF MAGNETIC MECHANICAL INDUCTION MOTORS AND METHODS OF MANUFACTURING

abstract 1271703024 issue 127 pp. 363 – 379 31.03.2017 ru 347
Based on the analysis of domestic and foreign scientific and patent literature, options for reducing the weight of electro technical steel in the magnetic circuits of electrical machines are explored. We have carried out a search for the best options of technology for the manufacture of magnetic cores of the stators of induction motors, aimed at increasing the utilization factor of electrical steel and improving the energy performance of electric machines. All options are described in detail and illustrated by drawings. We have listed the advantages and disadvantages of each method of manufacturing magneto-wires and the reasons why certain proposals of manufacturing technology cores have not been implemented in mass production. A variant of technology of manufacture of annular magnetic cores for mechanical induction electric motors is offered. The essence of mechanical design is to replace the laminated stator and rotor twisted from a strip of electrical steel, wound in the form of a ring with the simultaneous breaking-hell grooves with variable pitch under the stator windings and squirrel cage of the rotor coils. The effectiveness of the use of volute stator in mechanical electrical machines is confirmed in frequent controlled asynchronous torsion engine when tested pilot batch of the mechanical single-phase asynchronous motors for washing machines. This technology almost completely eliminates the problem of technological wastes of electro-technical steel regardless of the form of the stator bore (cylindrical, conical, flat end or flat line); it allows fully automate the manufacture of magnetic cores, greatly simplifies the stamps, makes them more durable

METHODS OF DIAGNOSIS STUDY FOR NUMBER OF STATIONS FOR INTERACTIVE MONITORING THE TECHNICAL CONDITION OF MACHINERY IN AGRICULTURE

abstract 1281704011 issue 128 pp. 188 – 199 28.04.2017 ru 347
Condition monitoring is a necessary element of the transport and special machinery in agriculture. The task of the control operations other than the determination of the technical state of the object is to determine the required amount of work, as well as rational amount of collateral the repair of which could be combined with the next maintenance. Based on the results of processing of the information, we may generate requests for service. In the conditions of uncertainty of receipt of requests for servicing of individual machines, estimated volumes and timing, we have am appropriate development of applied technique of justification of the number of diagnostic posts for interactive control of a technical condition of vehicles and special machinery in agriculture. The presented methodology is based on probabilistic methods, and allows the quick optimization of the number of existing posts interactive diagnostics in the enterprise, if necessary, translating the existing posts in "standby" mode, or Vice versa, returning from a reserve in "work" mode. The production and technical base of the enterprise service based on the specific assumptions are considered as a system of mass service (SMO), and the function of such a SMO – as the process of mass service. The process of queuing as applied to interactive diagnosis are "Markov" processes "death and reproduction" with a finite or countable number of States and continuous time. To describe the states of the system we use the system of the Kolmogorov equations for steady state of "Markov" process. On their basis, we have determined average queue length, time of stay orders in the queue, number of busy channels and the bandwidth of the CFR. Using the intensity of the requests and the service time of a single application for specific equipment, the article establishes the efficiency of online diagnosis posts. The result of the proposed applied methodology enables timely decision-making about the need for reconstruction or technical re-equipment of the company

INVESTIGATION OF THE PROCESS OF EVAPORATION OF CHOKEBERRY INFUSIONS

abstract 1261702009 issue 126 pp. 131 – 140 28.02.2017 ru 346
For the design of rotary-film evaporators of the technology for food production we need summary tables of performance parameters of the process. To obtain them it requires a significant amount of experiments that require a large investment of time and resources. Therefore the actual task is reducing the cost of designing of the technological process, due to the choice of optimal parameters of the rotor-film evaporator. This problem can be solved by conducting a small series of experiments aimed at identifying general mathematical dependences of the parameters of the processes of evaporation on the performance of the device. Based on the obtained dependencies it is possible to find design and selection of evaporators. The study proceeded from the assumption that the maximum thickening of the initial solution in the evaporator, it is possible while achieving the maximum possible temperature, the filing of the original solution in the apparatus and performance during repeated evaporation and infusions from the fruits of chokeberry. The calculation is performed taking into account the prevention of adhesion of evaporated solution on the walls of the apparatus and the rotor blades, which may reduce the quality of the end product. The data confirm the effectiveness of the method of repeated evaporation on the example of concentrating the water-alcohol extracts of black chokeberry

SECURITY ASSESSMENT PROBLEMS IN SAWMILL EQUIPMENT

abstract 1281704040 issue 128 pp. 546 – 557 28.04.2017 ru 346
The article deals with normative legal documents, regulating safety indicators of equipment, with particular focus on woodworking machinery, including log-processing equipment. General and specific requirements have been highlighted in terms of their analyses. The necessity of safety requirements’ specification in technical guidelines, with reference to construction of industry-specific trend equipment, according to newly accepted national, interstate and international standards for purposes of conformity assessment. Nonconformities were determined on the terms in Technical Guidelines of the Customs Union 021/2011, fundamental documents for woodworking equipment GOST EH 1070 and GOST ISO 12100. Relevant topic issues are declared in this work. Manufactures consider them when risk valuation is performed in point of existing equipment and that, under development non-standard equipment, connected with diversity of normative documents, absence of information about customers’ experience, accidents while operating comparable machinery, etc. The paper emphasizes complications, which participants of standard programs face, namely, development contractors and users, accredited test laboratories and certification bodies, state oversight authorities, when woodworking machinery conformity assessment is performed. The suite of safety metrics was suggested for valuation of log-processing equipment and two-level log frames, particularly, on the basis of technical guidelines requirements TG CU 021/2011 “On machinery and equipment safety”, and standards GOST EH 1070, GOST 12.2.026.0, GOST R 5454123 and GOST R 51898. The necessity of standard realization was demonstrated in relevance to obsolete methods of control over equipment (geometric and technology accuracy). GOST 10294 was accepted in 1990 and hasn’t been actualized since that time. That is the reason why it seems impossible to estimate equipment condition, as recommended monitoring facilities are missing

DEPENDENCE OF THE PRODUCTIVITY AND THE QUALITY OF WINES FROM THE PLANTING PLAN

abstract 1321708092 issue 132 pp. 1155 – 1165 31.10.2017 ru 346
The dependence of the productivity of the Riesling Rennel vineyards and the quality of table wine from it under the conditions of the Anapa-Taman Winegrowing Zone was studied. It is established that the vineyards of the Riesling Rhine variety are planted with the highest yield, planted according to the scheme of 3.5x1 m. In this embodiment, at a density planting shrubs 2857 pcs. / Ha, the yield of grapes was the highest - 131.4 c / ha. Maximum accumulation of sugars in the grapes observed in the variants with a width of 2.5 m aisle highest extract content from different wine stocks options with row spacing of 2.5 m where the amount of extractables amounted to 17.1 - 19.2 g / dm3 . The increase in the total concentration of aromatic compounds of up to 540 mg / dm 3 helps to improve the quality of white table wine, and further growth of aromatics to 1090 mg / dm3 - it reduces the organoleptic evaluation. High tasting marks (7.88-8.29 points) received wine materials from sites having a spacing of 3.5 m. Thus, considering the quality of the wine, the cost of planting material, laying and care of vineyards, it is worth considering the 3.5x1 planting scheme , 5 m more suitable for the production of quality table wines in the Black Sea agroecological zone of viticulture in the south of Russia

DESTRUCTION OF SOIL STRUCTURE WHEN CULTIVATING GRAPES

abstract 1331709042 issue 133 pp. 534 – 542 30.11.2017 ru 346
The ecological state of soil on the globe is unstable. Intensification of agricultural production is accompanied by negative trends in changes in soil fertility. One of the most important indicators of soil fertility is its structural state. With a long time cultivation of grapes in one place, the physical properties of the soil deteriorate. The purpose of our research is to study the process of destruction of soil structure during the cultivation of vineyards. The object of research is the soils of plots of various agricultural uses (vineyards, field crop rotation, forest belts). The research methods used in the work are route-field surveys, a laboratory study of the waterphysical properties of the soil. The article presents the data of the structural-aggregate composition of the soil from plots of various agricultural uses. From the data given, it can be seen that the soil occupied by the vine plantations is characterized by a poor structure and low structure of the arable horizon. The share of agronomically valuable aggregates is 40.4%, the structural coefficient is 0.68 units, while in the forest belt this figure is 5.7 units. The increased mechanical load on the soil during the cultivation of vineyards leads to a deterioration in the physical properties of the soil. Soil with low indicators of physical condition is more susceptible to erosion processes, such as water and wind erosion. Water erosion annually causes great damage to agricultural lands throughout the world. The article clearly demonstrates and scientifically substantiated the negative effect of the system of soil content of vineyards on the type of black steam. Also proposed are ways to reduce the mechanical load on the soil and prevent the development of degradation processes in the soils of vineyards
