1. Definition of electro-hydraulic servo pressure testing machine

The electro-hydraulic servo pressure testing machine is a high-precision pressure testing equipment controlled by an electro-hydraulic servo system. It combines the high load capacity of hydraulic transmission with the accuracy of servo control, and is able to test the mechanical properties of materials or components in high-pressure environments. Its core components include hydraulic system, servo control system, data acquisition system and mechanical structure.
2. Working principle
The working principle of the electro-hydraulic servo pressure testing machine is to control the flow and pressure of hydraulic oil through the electro-hydraulic servo valve to accurately adjust the load applied to the specimen. The servo control system monitors load and displacement in real time, and ensures the stability and accuracy of the testing process through feedback adjustment. Here is a brief description of its workflow:
1.Hydraulic system: Provide high-pressure oil source to drive the piston movement.
2.Servo control: Control the servo valve through electrical signals to adjust oil pressure and flow.
3.Data collection: Real-time recording of load, displacement, deformation and other parameters.
4.mechanical execution: Apply pressure to the specimen through a piston or clamp.
