| description | The article presents the results of theoretical studies of
the functioning of flow amplifiers, the purpose of which is to increase the useful power of the hydraulic steering
systems of heavy construction and road machines,
which is especially important when upgrading existing
equipment and designing a new one. Flow amplifiers
allow to increase the supply of working fluid to the
hydraulic cylinders for turning a multiple of the dosed
volume by the dosing pump. A distinctive feature of
the study is the consideration of two flow amplifiers of
throttling and volumetric types, working in pairs. The
design, the principle of operation are described, the main
calculated dependencies are presented, on the basis of
which mathematical modeling was carried out. To evaluate
the qualitative and quantitative characteristics of the
amplifiers, graphs of transient processes in the steering
hydraulic system, as well as the static characteristics of
the flow amplifiers, were obtained. The analysis of the
obtained dependencies showed acceptable accuracy and
quality of the hydraulic system. The results obtained can
be used in the synthesis of such systems. |
