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
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
Theoretical aspects of the regional housing market
formation are considered in the article. It is noted
that the economic reform of our country has shifted
to regional level of practical social tasks to ensure
the population to affordable housing. Housing construction,
until recently, acted as the growth driver of
the entire economy. Therefore researching of the
economy effect on the housing sector on effectiveness
in the development of the regional socioeconomic
system is very up-to-date and is in great
demand. The authors present the region definition as
a complex multilevel structure with its own economic
environment, dynamics of development, made
through part of the national economy. The article is
setting goals for regional development construction

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
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
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
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
