Abstract
The majority of the failures of trailbuilder hydraulic systems operating in the
north are connected with the influence of low negative temperatures. Therefore
there is a need to apply a prelaunch thermal preparation by means of the fluid
drive.
The requirement of power consumption minimization on the thermal
preparation of the fluid drive is especially topical during independent operation
of machines in conditions of low negative temperatures far from mechanization
bases where there are no constant sources of thermal and electric energy, or
warm rooms.
Nearly all earlier systems of thermal preparation of the fluid drive involve the
heating of oil which is in a hydraulic tank and the hydraulic line, moving in a
small circle. Thus hydraulic engines do not stay heated-up and the oil, which is
inside, is solidified, which considerably complicates the start of motion of the
mobile elements in the sealing areas. It is necessary to reduce the degree of
loading at the time of the first hydraulic engine start-up so reducing the intensity
of wear and prolonging the service life of elements of the fluid drive.
In order to study the hydraulic components at low temperatures in the
Tyumen State Oil and Gas University in the Department of Transportation and
Technological Systems under the leadership of Professor Sh. Merdanov, an
experimental installation of the thermal preparation of hydraulic elements was
developed. The research facility allows for all planned studies involving
measurement of the static and dynamic characteristics of the hydraulic drive.
The effect of the implementation of the proposed development is achieved by
reducing fuel consumption by heating the hydraulic system, resulting in an
increase in productivity, reducing the cost of repair and maintenance of the
hydraulic system, and increasing its service life.
Keywords: fluid drive, hydraulic cylinder, trailbuilders, operation, warming,
