The invention provides an integrally-controlled intelligent energy-storage reset electro-hydraulic actuator comprising a hydrocylinder, an energy-storing device, an electrical control cabinet, a servo motor, a gear pump and an oil tank. The electrical control cabinet is connected with a driver of the servo motor which is connected with the gear pump to drive the same to operate to deliver hydraulic oil stored in the oil tank to the energy-storing device, and the hydrocylinder is connected with the energy-storing device. By the integrally-controlled intelligent energy-storage reset electro-hydraulic actuator, a traditional driving mode of a mechanical gear is replaced by the world's most advanced hydraulic integrated technology; the high-precision servo motor is adopted as the driving force of the pump, and the servo motor is controlled by pulsed quantity to operate, so that performances of high precision and high response are possessed; the integrally-controlled intelligent energy-storage reset electro-hydraulic actuator is large in output force and torque, small in size, and high in precision and movement speed when used for switching and regulation control.
Description
technical field [0001] The invention belongs to the field of actuators, in particular to an integrated control intelligent energy storage reset electro-hydraulic actuator. Background technique [0002] The actuator is generally composed of two parts: the actuator and the adjustment mechanism. The adjustment mechanism directly changes the parameters of the production process through the actuator to make the production process meet the predetermined requirements. The actuator receives the control information from the controller and converts it into the output of the drive adjustment mechanism (such as angular displacement or linear displacement output). It also uses appropriate actuators, but the requirements are different from the adjustment mechanism. The actuator is directly installed on the production site, and sometimes the working conditions are harsh. Whether it can maintain normal work directly affects the safety and reliability of the automatic adjustment system. ...
