Problems solved by technology
[0004] The invention provides an electro-hydraulic servo control device, which can effectively solve the above-mentioned background technology. The electro-hydraulic servo control device currently on the market. The hydraulic station in the metallurgical industry uses an asynchronous motor to drive the oil pump to generate the pressure required by the system. The motor operates and does not act on the oil cylinder. When the oil cylinder is not in operation, the flow required by the system is small, and the excess flow flows back to the oil cylinder through the overflow valve, resulting in waste of electric energy, high oil temperature, and high noise of the asynchronous motor

The invention discloses an electro-hydraulic servo control device. The device comprises a reset circuit and an AC circuit, the reset circuit is connected with an input terminal of a disconnect switchQ1, an output terminal of the disconnect switch Q1 is connected with an input terminal of an AC contactor KM201, the AC contactor KM201 is connected with an input terminal of a disconnect switch Q2, and an output terminal of the disconnect switch Q2 is connected with an input reactor L1 and a cabinet top fan M2. The device is scientific and reasonable in structure, and safe and convenient to use,an electro-hydraulic servo system adopts a servo motor and a quantitative pump system, can be started and stopped at any time, and supplies on demand, and almost no overflow produces, so that the energy saving effect is brought; through servo driver control and oil pressure PID closed loop control, the revolving speed is adjusted according to system flow demands, the electric energy is saved, a asynchronous motor is replaced with a permanent magnet synchronous motor, the noise is low, the response is fast, the unnecessary flow is saved, fuel consumption is reduced, and oil temperature is lowered.
Description
technical field [0001] The invention relates to the technical field of servo control, in particular to an electro-hydraulic servo control device. Background technique [0002] "Servo" - the word comes from the meaning of "slave" in Greek. People want to use the "servo mechanism" as a handy taming tool to obey the requirements of the control signal. Before the signal comes, the rotor stands still; the signal comes After arriving, the rotor rotates immediately; when the signal disappears, the rotor can immediately stop by itself, because of its "servo" performance, hence the name - servo system; [0003] However, the hydraulic station of the electro-hydraulic servo control device currently on the market in the metallurgical industry uses an asynchronous motor to drive the oil pump to generate the pressure required by the system. The flow is small, and the excess flow flows back to the oil cylinder through the overflow valve, resulting in waste of electric energy, high oil tem...
