Problems solved by technology

[0002] Chemical hydrogen equipment is often subjected to the interaction of stress-high temperature and hydrogen medium, which leads to the deterioration of the material performance of the equipment, and then the failure of the equipment, which seriously affects the safe operation of the equipment
For this reason, the material performance test and its test device under the interaction of stress-high temperature and hydrogen medium are very important. However, due to the flammable, explosive and easy-to-leak characteristics of hydrogen, the existing material performance test device cannot simultaneously realize complex stress-high temperature. and metal material performance test in hydrogen environment

Embodiment Construction

[0043] For ease of understanding, here in conjunction with accompanying drawing, specific testing device of the present invention and its operation process are further described as follows:

[0044] The structure of the present invention is as Figure 1-5 As shown, each component of the present invention is described in detail below:

[0045] 1. Host loading framework

[0046] The host loading frame can realize the creep-durable and tension-tension alternating load loading of the sample, and provide a hydrogen environment box to stabilize the installation platform. The host loads frameworks such as figure 2 As shown, it is composed of the lifting mechanism above, the horizontal surface of the workbench and the base below the workbench.

[0047] Specifically, if figure 1 , 2 As shown, the base is a cuboid space composed of a lower base plate 24, an upper base plate 25, and four angle steels 25. The loading drive mechanism composed of a servo motor 7, a reducer 8 and a bal...

Abstract

The invention relates to a high-temperature hydrogen environment material performance test device. The device includes a hydrogen environment box with samples inside, and a host loading frame equipped with pull rods. The hydrogen environment box is set on the host loading frame; Assemblies, the tie rods pass through the hydrogen environment box and are fixed to the lower holding part; the hydrogen environment box is connected to the hydrogen supply pipe, and the hydrogen environment box is also equipped with a deflation solenoid valve; the device also includes Sensors for sample deformation, sample ambient temperature, and hydrogen pressure around the sample, and control components for monitoring and processing the information collected by each sensor. The device can realize online the creep performance, durability performance and pull-pull alternating load fatigue performance test of metal materials under the hydrogen environment, and can ensure the accuracy of the test results, and its work is reliable, stable and efficient.

Description

technical field [0001] The invention relates to the field of material performance testers, in particular to a high-temperature hydrogen environment material performance test device. Background technique [0002] Chemical hydrogen equipment is often subjected to the interaction of stress-high temperature and hydrogen medium, which leads to the deterioration of the material properties of the equipment, and then the equipment fails, which seriously affects the safe operation of the equipment. For this reason, the material performance test and its test device under the interaction of stress-high temperature and hydrogen medium are very important. However, due to the flammable, explosive and easy-to-leak characteristics of hydrogen, the existing material performance test device cannot simultaneously realize complex stress-high temperature. And metal material performance test in hydrogen environment. Therefore, there is an urgent need for a high-temperature hydrogen environment m...
