The metal bellows expansion joint pressure testing machine adopts a floor-standing gantry structure, with microcomputer-controlled electro-hydraulic servo system. It can perform stress, strain, and displacement control modes, automatically collect test data, plot curves, and automatically print test reports. This testing machine can conduct mechanical property testing and analysis on metals, non-metals, and composite materials, widely used in industries such as aerospace, petrochemicals, machinery manufacturing, plastics and rubber, ceramic building materials, metal materials, and construction engineering.

Performance characteristics of the metal bellows expansion joint pressure testing machine:
Automatic stop: After the test fracture, the moving beam automatically stops moving;
Automatic range switching: Automatically switches to the appropriate range based on the load size to ensure the accuracy of measurement data;
Condition module: Control data and sample conditions during the test can be made into modules, facilitating batch testing;
Automatic speed change: The speed of the moving beam during the test can automatically change according to a pre-set program or be manually set arbitrarily;
Automatic calibration: The system can automatically calibrate the accuracy of the indicated value;
Automatic saving: Test data and curves are automatically saved after the test;
Process implementation: The test process, measurement, display, and analysis are all completed by the microcomputer;
Batch testing: For samples with the same parameters, one setting can complete tests sequentially;
Test software: Chinese WINDOWS interface, menu prompts, mouse operation;
Display method: Data and curves are dynamically displayed during the test process;
Curve traversal: After the test is completed, the curve can be re-analyzed, and the test data corresponding to any point on the curve can be found with the mouse;
Curve selection: Force-deformation, force-time, deformation-time, and other curves can be selected for display and printing as needed;
Test report: Can be compiled and printed in the format required by the user;
Limit protection: Has both program control and mechanical limit protection;
Overload protection: Automatically stops when the load exceeds 3-5% of each range value.
