Description
technical field [0001] The invention belongs to press technology, and in particular relates to a press pump control hydraulic system and a control method thereof. Background technique [0002] The existing hydraulic control system of the press has two typical hydraulic control systems, one is the valve-controlled hydraulic system of the press, and the other is the pump-controlled hydraulic system of the press. [0003] The valve-controlled hydraulic system of the press requires precise hydraulic servo valves, which have high requirements on the quality of the working medium, so the system itself has poor anti-pollution ability, resulting in inconvenience in later maintenance; its hydraulic power components, actuators, control components, and hydraulic accessories Relying on pipeline connection, so the degree of integration is low, and the installed area is large; the large overflow loss of the valve-controlled hydraulic system itself leads to serious waste of energy and seri...
