The use of regenerated oils reduces the
consumption of fresh oils for refilling, while oil
filtration during the operation lengthens their
service life and reduces the consumption of fresh
oils for replacement. To restore waste oils, a variety
of technological operations are used, based on
physical, physicochemical and chemical processes.
They are aimed at treating the oil in order to
remove aging products and pollution from it. The
studies have shown that the most effective means of
recovering the quality of waste oils are small-size
regeneration plants. The main difficulty in creating
small-sized regeneration plants is the selection of a
sufficiently effective, environmentally safe and
economically justified method for the regeneration
of waste oils, as well as its hardware design. This
work is aimed at creating an efficient centrifugal
cleaner
The article examines the issues of increasing the efficiency of the system of technical operation of mobile agricultural machinery by means of monitoring the state of units and aggregates of the latter through diagnostics. The problems of complex diagnostics of diesel fuel equipment are investigated. The urgency of diagnosing a fuel injection pump without dismantling from the engine is shown from technical, economic and environmental points of view. The effect of operational malfunctions of some devices of fuel equipment on parameters of its operation as a whole is analyzed. On the basis of the analysis of diagnostic devices application, their grouping is suggested. The parameters to be studied in connection with peculiarities to decide whether it is possible to estimate the technical state of the fuel injection pump without dismantling from the internal combustion engine are indicated. Based on peculiarities of the fuel injection pump technical state estimation, a research program is developed and the results of the research are presented. Specific features of testing the fuel injection pump are indicated. Analysis of the results of the research shows that a smaller error in the change of the cyclic fuel feed rates supplied by the fuel injection sections takes place at the engine speed corresponding to the indicated power. The conclusion is made that the presented research results can be used as a basis for developing a technique (technology) for diagnosing the fuel injection pump without dismantling from the internal combustion engine

Technologies of fruits storing known at the present
time, solving actual problems – slowing down
biochemical processes, inhibiting ethylene synthesis,
do not provide fully the preservation of quality of
fruits due to not taking into consideration the
peculiarities of microflora of fruits and
microbiological processes, taking place during storage.
Purpose of the research: investigation of influence of
complex treatment of fruits with electromagnetic fields
of extremely low frequency (ELF EMF) and the biopreparation
“Vitaplan” on changing of losses of
biologically active substances in the process of longterm
storage. Objects of the research: apples of the
Idared variety and pears of the Conference variety,
regionalized in the Krasnodar region. Mass shares of
the vitamin C and P-active substances were measured in the process of storing. ELF EMF treatment was
conducted on an experimental installation. Fruits were
exposed to the action of electromagnetic fields with
specified parameters. Complex treatment of fruits
(apples and pears) with ELF EMF and the biopreparation
“Vitaplan” before dispatching for storage
allows preserving the biologically active substances –
the vitamin C and P-active substances – to the
maximum degree. Synergetic effect, appearing due to
the complex action of electromagnetic field and the
bio-preparation, allows decreasing the processing time
in the electromagnetic field
The mechanical activation allows creating a active
state in a solid, opening the prospect for holding and
accelerating the chemical reactions between solids and
getting materials in a nonequilibrium state. As a result
of mechanical activation of the powder compositions
of the active phase transformations occur in them,
which lead to the formation of solid solutions and
various intermediate connections, providing dispersion
and dispersion hardening of materials included in the
composition. The results of the study of the
granulometric composition, the phase transformations
and structure evolution in multiphase materials with
SME Ni-30%at.Ti-20%at.Hf and Ni-33%at.Ti-
18%at.Zr at different stages of the process of
mechanical activation carried out in planetary ball mill
the centrifugal type is represented in the article.
During mechanical activation, a composite mix is
assimilated by the particles of processed material input
of mechanical energy in the form of new interfaces,
defects of the crystal lattice. At collision of particles
and grinding bodies in contact high local temperature
and pressure occur, which in some cases can lead to
melting of the most fusible components. When a local
increase in temperature between the particles of
titanium, hafnium, zirconium and carbon solid-phase
reactions become possible due to diffusion of atoms of
one component into the crystal lattice of the other.
Experimental studies have shown that the use of
mechanical activation allows creating an effective
technology of preparation of the starting material for
high-speed flame spraying
The aim of the article has been the study of deflection
laws in tractor oversize low-pressure tires, intended for
class 5 tractor propulsion. The research method was
experimental. The "tire tester" and specially designed
devices for determining the deflections of the inner and
outer tube relative to the rim in the circumferential,
radial and collateral directions have been used in it. A
number of factors determine outcome indices of the
wheel with pneumatic tyre. Among them the ability of
the tire to deform so that at low - hysteresis losses in the
rubber-cord casing and admissible stresses in it, based on
resource, the largest area of contact with the supporting
base has been created. This circumstance is of particular
importance in the development of tractor tires of low
pressure, deflection characteristics of which are poorly
studied at present. Analysis of experimental studies
showed the necessity of the feasibility of creating the tire
with the cord orientation in its casing so that in the zone
of perception of the vertical and longitudinal forces the
cord threads would work in a mode close to the
extension, but in the area of contact it would work in
bending. These requirements will best meet the tire in
which the cord threads are parallelly located in adjacent
layers and directed at a predetermined angle in the
direction of effect of the axial forces on the wheel in oncoming fibers

In this work, we consider the design and development of
neural network software module for prediction of
electricity consumption in the system of support of
decision-making power control. Two prediction models
support the software module: regression model and
neural network model, based on multilayer perceptron.
Software development to predict power consumption in
the system of decision-making today is one of the priority
directions in the Russian power industry. Therefore, the
work associated with the development of methods and
algorithms of forecasting of power consumption in the
power sector, is surely relevant

Modern extraction systems are characterized by a change in the parameters of the production cycle under the influence of a number of causes caused by the structural dynamics of systems. Information systems can successfully function by solving the tasks of collecting, processing, analyzing and distributing real-time information, which involves the use of modern information technology methods. With increasing requirements to the volume, speed and quality of information on the progress of extraction processes, modernization of information systems is required, allowing to make informed decisions by management structures. In the article the regularities of mass transfer of n-components in carbon dioxide of the solid-liquid system are considered. The effect of spontaneous interfacial convection in the mass transfer of individual components under the influence of an electromagnetic field of low frequency is detected. The joint mass transfer of extractive substances during spontaneous interfacial convection leads to an increase in the mass transfer coefficient of eugenol compared to its diffusion mass transfer
