Abstract

The invention relates to a stress corrosion testing device, comprising a stress corrosion container, a stress applying system and a control testing system, wherein the stress corrosion container is internally provided with corrosive medium and a test sample, and is arranged on a horizontal rack; the stress applying system comprises a transmission part which is arranged on the horizontal rack, a left test sample chunk is connected on the transmission part, and the left test sample chunk and a right test sample chunk are matched to clamp a test sample; and the control test system comprises a motor controller, an operating terminal and a load sensor, wherein the load sensor is arranged on the horizontal rack and is connected with the right test sample chunk, and the motor controller and the load sensor are connected with the operating terminal. The stress corrosion testing device has the benefits of: reducing the influence of the weight of spare parts of equipment when in loading, having convenient control, large speed reducing ratio and self-locking function, being suitable for different test conditions and having wider application range.

Description

technical field [0001] The invention relates to a stress corrosion test device. Background technique [0002] Stress corrosion is a phenomenon of spontaneous delayed failure of metal components carried by equipment in a specific medium environment, and is one of the main reasons for equipment failure. Stress corrosion research is an important field of equipment anticorrosion and safety reliability research. The stress corrosion test device is an important basic equipment for studying the process and mechanism of stress corrosion. [0003] The test equipment for stress corrosion research is mainly divided into static test equipment and dynamic test equipment. Static equipment is not conducive to the control of test parameters and the collection of experimental data. Dynamic test equipment is convenient for real-time control of test parameters and data collection. However, there are few dynamic stress corrosion equipment at present. Among them, only the slow strain tensile s...
