Abstract
FIELD: mining industry. SUBSTANCE: hydraulic system of mining machine has regulated pump, hydraulic control valves, controlling hydraulic cylinders for varying pump delivery, power supply unit, flow regulator, two pressure regulators, unit for control of pressure level in hydraulic system and return and pressure pipelines. Pump outlet, through respective hydraulic control valve, is hydraulically connected with each hydraulic motor. One of working hollows of controlling hydraulic cylinder is hydraulically connected with pressure pipeline. The second working hollow of controlling hydraulic cylinder is hydraulically connected through flow regulator with pressure pipeline, and through parallel pressure regulator, with return pipeline. Output of unit for control of pressure level in hydraulic system is hydraulically connected with control channel of one of pressure regulators. EFFECT: higher efficiency. 4 cl, 1 dwg
