2.The hydraulic system

The hydraulic oil in the tank pumps the high-pressure pump into the oil circuit through the motor, which flows through the one-way valve, the high pressure filter, the differential valve group, and the servo valve, and enters the cylinder.The computer sends out the control signal to the servo valve, controls the opening and direction of the servo valve, and thus controls the flow into the cylinder, and achieves the control of the iso-velocity test force.
