At the present time there is a problem in storage
of agriculture machine-tractor park, because when
operating of agricultural machinery parts thereof
are covered by contamination. The most heavily
becomes dirty machinery working in the toughest
conditions. Pollution promotes decrease the
operational reliability, accelerating of corrosion
and aging, reduce the quality of maintenance
service and performance technique. One of the
number of important factors when setting
technique for storage is the clearing of by of
various types pollution, because the during
storage of cleaned surfaces, components and parts
are subjected still greater destruction and
corrosion. Removal of various kinds of pollution
is an important technological process which has a
significant impact on the preservation of
appliances, performance of work, the quality of
the repair and maintenance of cars, culture,
production and human health. The article contains
a classification of contamination depending on the
difficulty of their removal and density, basic
information on techniques and devices for
purification of units and parts of agricultural
machines, as well as on substances used for this.
We have reviewed bombardment of surfaces with
contaminated carbon dioxide ice particles that
leads to its full destruction. We have improved technology and created a universal device and the
experimental plant for cleaning parts and
assemblies prior to storage, which are not only
inferior, but also in the majority superior to
technical and economic performance of existing
analogues
The carried out analysis studies the influence of
various factors on the preservation of
agricultural products and shows that it is largely
determined by design features of machinery and
technological methods of use. The efficiency of
agricultural and mobile trailer machines has
been forming by service and storage. Low
quality of work associated with the storage of
agricultural machines is conditioned by the fact
that the lack of financial capacity of rural
producers on acquisitions of modern equipment
and materials for carrying out the preparation of
for long storage, and also the construction of
modern agricultural machinery storage sites. If
a car can be fully or partially protected from the
solar radiation, rain and snow, simply by
removing it in the room, under a canopy or
covered with a protective cover, by the
formation of condensation on the surface of the
machine units and parts these ways to protect
do not work. Enhancing of preservation of
agricultural machinery is possible when
protecting the vehicles from atmospheric
precipitation in the form of snow and rain,
influence of solar radiation, and also due to the
change heat exchange processes of the machine with the environment that prevents the
formation of moisture condensate on its surface,
ie. we have to create conditions when cooling
rate at which the surface of the machine would
be equal to or less the rate of cooling air. This is
possible through the use of a special design,
which would prevent the intense heat radiation
of the machine into the environment, ie, would
reflect heat rays using its surface and return
them to its surface and thus fulfill the role of the
heat shield
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
