Principle of electro-hydraulic servo universal testing machine

Mechanical structure of electro-hydraulic servo universal testing machine: The main part of this equipment is composed of two parts: height-adjustable support frame [composed of machine base, screw rod and mobile crossbeam (lower jaw seat)] and working frame [composed of working oil cylinder, piston, platen, bracket and upper crossbeam (upper jaw seat)].

The control cabinet part is composed of a fuel tank, an oil pump, a manual control valve, an electro-hydraulic proportional valve, etc., which serves to provide stable and continuous high-pressure oil to the main body part. As the actuator of the control system, the proportional valve plays a control role in the hydraulic system according to the signals sent by the microcomputer.

The principle of the control system of the electro-hydraulic servo universal test machine: The control system is composed of a high-reliability industrial control special computer, high-precision data acquisition and control board, sensor (including force sensors, extensometers, photoelectric encoders) and other components.
