The invention relates to the field of compressed air energy storage sealing materials, in particular to a device for simulating the caulking state of a flexible sealing material. The device comprises a high-pressure control system, a test chamber and a connecting pipeline. An annular lining with a prefabricated crack, a flexible sealing layer and a high-pressure air bag are sequentially arranged in the test chamber from outside to inside, and the high-pressure air bag applies radial pressure to the flexible sealing layer through pressure change under the action of a high-pressure control system and is used for simulating the influence of the lining crack on the caulking performance of the flexible sealing layer under the condition of high internal pressure. The caulking behavior and the damage characteristic of the flexible sealing material under different working conditions can be simulated and evaluated by adjusting the width of the lining crack, the material and the thickness of the flexible sealing layer and the loading pressure parameter. According to the method, the stress state and caulking characteristics of the flexible sealing layer in the compressed air energy storage cavern can be truly restored, and a test means is provided for engineering applicability evaluation of the flexible sealing material.

The application provides a device and a test method for monitoring diffusion of hydrogen atoms across a grain boundary by using SKPFM, and relates to the technical field of hydrogen energy utilization. The device for monitoring diffusion of hydrogen atoms across a grain boundary by using SKPFM comprises a target grain boundary to be researched, a cantilever, an electrolytic cell, a platinum wire and a direct current power supply. The method is as follows: for a columnar crystal material after directional solidification, a certain grain boundary is determined as the research grain boundary, then a sample of the cantilever connected with the electrolytic cell is prepared, hydrogen atoms diffuse to the research grain boundary and gradually cross the grain boundary during the electrolysis process, and continuous scanning is performed on the grain boundary position by using SKPFM, so that the behavior of hydrogen crossing the grain boundary can be observed in real time. Compared with other traditional methods, the method of the application realizes the diffusion behavior of hydrogen atoms across the target grain boundary, high-throughput research and real-time monitoring research through the design of the device structure and the test method, improves the hydrogen embrittlement resistance of the material, and the conclusion is real, reliable and guaranteed, and is beneficial to industrial popularization and use.
