AI Technical Summary
Existing high-pressure gas testing systems, especially high-pressure hydrogen testing systems, lack testing equipment and methods for the torsional resistance of components, which makes components prone to structural damage under high-pressure loads, affecting service reliability and safety.
A workpiece torsion device with internal pressure was designed, including a test fixture, a pressurization component, a gas source system and a purging component. After nitrogen and hydrogen replacement and temperature adjustment, the torsion performance of the workpiece is tested. An explosion-proof motor is used to provide torque and the torque of the workpiece is measured by a torque sensor.
The torsional performance test of workpieces used in high-pressure hydrogen was achieved, ensuring the safety and reliability of the workpieces in a high-pressure hydrogen environment and avoiding leakage accidents caused by torsion.
