The article presents a technical diagnostics of a car as a complex of goals and tasks connected with
trouble-shooting of mechanisms and systems in
order to eliminate them. We have considered the
stages of computer diagnostics of different
automobile systems such as diagnosing the engine,
the brake system, steering and suspension. We have
analyzed their components, the ways of troubleshooting
and elimination recommendations. The
article presents the main troubles transferred from
the electronic control unit. The article also presents
the stages of diagnosing the engine including
external examination, listening to abnormal noises,
checking the operating fluids and the engine
management system, diagnosing the basic engine
systems and checking the cylinders being filled.
The article contains the list of main troubles and
their reasons. One can also see diagnosing the brake
system, its defects and remedies. The article
presents diagnostics and repair of the suspender and
graphics describing the check of the dismantled
shock strut at the stand and tests of the shock strut
without being dismantled. We have analyzed
computer diagnostics and the problems it solves
One can see some density irregularity within the roll
in the baler with a chamber of constant volume. We
have found out that the maximum density of hay roll
width (the baler width) is observed in the middle part.
This is due to the shape of the hay roll entering the
baler. To even the hay rolls they have mounted some
rotating disks having some inclined spring pins above
the baler. To improve the roller distribution the disks
above the baler have been pushed forward forming a
tapering gap. The evening discs rotating above the
moving roll will cause some relative motion of hay
particles. The interaction of the evening disks with
the hay roll in the vertical plane will be determined
by the elasticity of the hay roll and the weight of the
frame with the disks. We have studied the trajectories
of hay particles motion with the help of MathCad
program. We have had the following initial
parameters: the degree of compaction (decrease of the
roll height when evening), the friction coefficient, the
angle rate of the evening disks, the number of pins and the speed of the hay roll. As a result we have got
the trajectories of the hay particles motion when the
evening disks functioning. The analysis of the
trajectories has allowed to establish some basic
parameters of the evening device such as the distance
of 0.15…0.2 m between the pins; the degree of
compression while evening 20...25 %, the angle rate
of the evening discs 23...30 rad / s and the diameter
of the evening disc 0.74 m. The application of the
evening device in the form of the disks with pins
provides a uniform distribution of hay particles
edgewise of the baler ensuring preliminary hay roll
seal press before passing to the baler pressure
chamber that contributes to getting the rolls with
larger mass and a uniform distribution of hay density
inside the roll
For cleaning and disinfection of motor vans we can effectively apply installation for the treatment of work surfaces with a disinfectant spray. Disinfection unit is a generator of hot mist with a device for
dispersing
Potato is cultivated in 130 countries on an area of over
18 million hectares; it annually gives more than 300
million tons of tubers. The share of the Russian
Federation accounts is about 11% ... 14% of total
production. The resulting potatoes consumed in food, animal feed, technical purposes, seed fund. According
to the Ministry of agriculture of Russia, the largest
number of potatoes in our country (89 %) is produced in
peasant farms and personal farms of citizens, the area of
cultivation of which make up about 2.7 million hectares.
At such farms for the harvest, they use mainly potatodiggers,
followed by selection of crops manually. The
use of diggers in small areas of planting is more costefficiently
in relation to the harvesting combine. In
addition, the parameters requested for ATT to damage
potatoes when harvesting with the diggers (3%) are
higher than during harvesting by combine harvester
(5%). As practice shows, for the use of cleaning units,
even under optimal harvesting conditions in the hopper
of the combine, there are soil and vegetable impurities.
There are many different devices intended to localize
the problem. Based on the foregoing, we can conclude
that it is necessary to pay considerable attention to the
quality of work of excavating working bodies, because
it affects the productivity of the functioning of the
whole machine. Currently, there are widespread potato
aggregates with the receiving part, equipped with side
disks, spaced along the edges of the plowshares. The
disks cut off the raised layer of soil from between the
rows. This entails improving the performance of the
potato harvester. The most efficient and economical
from the point of view of energy consumption, is the
work of passive disks with hooks. The quality of potato
harvesters depends on the design and performance of
excavating bodies. The proposed design solution for an
excavating body increases the productivity of harvesting
machines
The mathematical model presented in this article allows you to choose rational values and ranges of design and technological parameters of body separation, as well as their further optimization
We have presented the technological scheme of a dispersal device which allows to increase the efficiency of cleaning and disinfection of automotive vans with specialized solutions
The effectiveness of disinfection depends on used disinfecting materials for vans, their actions and technological parameters of the installation for applying disinfectants. Hot mist generators provide uniform distribution of particles of disinfectant solution inside the van for transportation of agricultural products. The parameters of the generator of hot mist affecting the quality of disinfection were investigated. Tests were conducted for the vans used to transport agricultural products. For studies we used the vans in operation, which transport farm animals (pigs) and had been disinfected before. Sampling for the research on contamination was performed with pre-prepared swabs. Factorial experiment was planned with using scheme #32, and as a result of significant factors in the univariate experiments we set a temperature of the aerosol disinfectant solution and the duration of surface treatment. As an optimization function we have chosen disinfection efficiency of bodies of vehicles carrying agricultural products. Comparing the results of the experiments on different groups of microorganisms we have found that the optimal mode of hot mist generator with a dispersing device are: the processing time of 1 m2 - 8.5 at the processing temperature - 65º C
The mathematical model presented in this article is designed to assess the probability of occurrence probability of technological failure potato harvester according to the specific conditions and usage
