Ultra-high pressure hydrogen environment portable environmental mechanical test device

Abstract

The invention discloses an ultrahigh-pressure hydrogen environment portable environmental mechanics testing device, which comprises a seal cap, an upper vessel body connected to the seal cap, a lower vessel body connected to the upper vessel body, an upper tension bar and a lower tension bar. The upper end of the upper tension bar is connected to a stretcher. The upper tension bar extends into the seal cap, the upper vessel body and the lower vessel body. The upper part of the lower extension bar extends into the lower vessel body. Opposite ends of the upper extension bar and the lower extension bar are both provided with a chuck. The upper vessel body comprises an upper chamber provided with a first vertical through hole; an upper annular support member, a first dynamic seal structure and an upper guide ring which are successively arranged from top to bottom between the upper extension bar and the upper part of the first vertical through hole; and a lower guide ring, a second dynamic seal structure and a lower annular support member which are successively arranged from top to bottom between the upper extension bar and the lower part of the first vertical through hole. The seal cap and the upper vessel body form an upper cavity, and the upper vessel body and the lower vessel body form a middle cavity. The testing device of the invention has characteristics of small size, light weight, good sealing property and strong durability.

Description

technical field [0001] The invention relates to the technical field of high-pressure hydrogen experimental equipment, in particular to an ultra-high pressure hydrogen environment portable environmental mechanics test device that can be used in conjunction with a common stretching machine. Background technique [0002] Hydrogen energy, petrochemical industry, nuclear power and ocean development are important components of my country's energy strategy. In these fields, equipment often needs to operate in high temperature, high pressure and high corrosion environment. [0003] Hydrogen energy is a promising clean energy. The most effective way to store and transport hydrogen energy is high-pressure storage and transport. In Japan and the United States, hydrogen fuel cell vehicles have been introduced to the market. The hydrogen pressure of hydrogen refueling stations is as high as 98MPa, while The pressure of the hydrogen storage tank in a hydrogen fuel cell vehicle is also 70...

AI Technical Summary

Problems solved by technology

Only one experiment can be carried out at most every day. Due to the huge investment in manpower and material resources, the cost of each experiment is as high as tens of thousands of yuan.

For this type of experiment, both the laboratory construction cost and the experimental cost are very huge, which is unbearable for general enterprise research institutions

[0005] At present, the research on high-pressure hydrogen environmental devices in my country is still at a relatively backward stage, and the environmental devices produced now are below 40MPa, and it is impossible to mass-produce 100MPa hydrogen environmental devices
