Application Scope:
The microcomputer-controlled hydraulic universal testing machine is a closed-loop control device used for testing the mechanical properties of materials. It is mainly applied to metallic, non-metallic, and alloy materials for tensile, compressive, bending, and shear tests, covering industries such as construction, metallurgy, aerospace, scientific research, education, and biomedical fields.
Product Features:
1. The microcomputer-controlled hydraulic testing machine is based on a electro-hydraulic closed-loop control system, achieving precise loading through the coordinated operation of sensors, controllers, and actuators.
2. The system integrates three-channel closed-loop control for test force, displacement, and deformation, supporting multiple control modes such as constant stress rate, constant strain rate, and fixed displacement, with a control accuracy of ±0.5% when the set value ≥10%FS.
3. The equipment generally adopts a four-column or six-column mainframe structure with the hydraulic cylinder at the bottom, providing a stable loading frame.
4. Equipped with an independent hydraulic clamping system with a separate oil supply, ensuring stable clamping force unaffected by main system load pressure fluctuations.
5. Integrates triple safety mechanisms: software limit protection, mechanical hard limit, and overload protection; emergency braking is automatically triggered when the test force exceeds 95% of the rated value.
