Method for controlling a hydraulic system with the proportional throttle valve

摘要

a control hydraulic powered valve du0142awiu0105co - proportionate, in which oil from the tank (1) is pressed by a hydraulic pump (3) driven by the induction motor (2) powered by the frequency converter (11) is characterized by the fact that the plc controller (10) controls the frequency changer (11),rozdzielaczem changeover device the direction of movement (4) actuator (5) and by constituting the electronic circuit card control (9) controls at least one valve du0142awiu0105co - proportionate (6), whereby the oil flowing out of the actuator (5) passes through at least one valve du0142awiu0105co - proportional (6) placed between the winch and the oil tank, and a filter (7) to the oil tank (1),in addition, a controller plc (10) collects with the transducer position (8) information about a position actuator (5) and on this basis, through control card (9) changes wysterowanie du0142awiu0105co - proportional valve (6), and by przemiennik frequency (11) changes the hydraulic pump (3).
