Description

technical field [0001] The invention relates to a multifunctional hydraulic servo amplifier device of a computer automatic control system. Background technique [0002] In the hydraulic servo control system, its servo components are composed of servo valves, relief valves, proportional valves, etc., and are used to control large hydraulic devices such as hydraulic cylinders. The control interfaces of these servo components are different, and the control current is generally tens of From milliamps to several amps, the output control signal of the electrical control system or computer must be driven and amplified to control servo devices such as servo valves and proportional valves, and finally drive oil cylinders or other large hydraulic devices to achieve the purpose of control. Hydraulic equipment is often used for steel rolling, lifting, and moving heavy objects. Most of the existing hydraulic servo control systems have technical problems such as simple functions, slow res...
