The main function of hydraulic actuators is to convert hydraulic energy into mechanical motion, which is used to drive various mechanical equipment or systems. For example, hydraulic actuators can drive valve opening and closing, control the movement of robotic arms, lift heavy objects, etc.
Hydraulic actuators work through hydraulic systems, using the pressure of liquid (usually oil) to transmit force. The hydraulic pump pressurizes the liquid and then delivers it to the actuator through a pipeline. The piston or cylinder inside the actuator moves under pressure to complete the required operation.
