Dependent twin-engine hydraulic drive of the drilling rig with a mechano-hydraulic variable pump control circuit

Abstract: The work is devoted to the study of an adaptive hydraulic drive for tool feed of a mobile drilling rig. The analysis of the ways of regulation of the considered hydraulic systems is carried out, the criteria and parameters of their functioning are determined. As a result of the analysis, an original circuit design of an adaptive hydraulic drive was applied, where the tool is fed using an adjustable volumetric hydraulic motor with a hydraulic control loop, taking into account the changing load on the tool durin… Show more
