Problems solved by technology

However, the bulk of the environmental chamber makes it impossible to precisely control the test temperature inside the environmental chamber.
In this way, the current status of the existing environmental chamber increases the manufacturing cost of the equipment, and also limits the pressure of environmental testing, further restricting the development of the environmental chamber

Embodiment 1

[0053] Embodiment 1: First, unscrew the 8 bolts between the lower kettle body and the middle kettle body, and separate the lower kettle body from the middle kettle body. Put the double-helix heating tube into the upper port of the lower kettle body and lead the two tubes out from the liquid inlet and the liquid outlet respectively; open the fixing nut at the bottom of the lower kettle body, push the lower stretching rod into the lower kettle body, And take out the lower stretch rod from the upper opening of the lower kettle body;

[0054] Install the two ends of the tested sample to the lower end of the upper stretching rod and the upper end of the upper stretching rod respectively, then reinstall the lower stretching rod from the upper opening of the lower kettle body and pull it out from the lower opening, and reinstall and fix it nut, and tighten the fixing nut. If it is necessary to carry out a high-pressure liquid experiment, fill the liquid into the hollow cavity at thi...

Abstract

The invention discloses a temperature-controllable high-pressure environmental mechanical test box which comprises a sealing cover, an upper kettle body connected with the sealing cover, a middle kettle body connected with the upper kettle body, a lower kettle body connected with the middle kettle body and provided with a temperature control solenoid, an upper stretching rod and a lower stretchingrod. The upper end of the upper stretching rod is connected with a stretcher, the upper stretching rod extends into the sealing cover, the upper kettle body, the middle kettle body and the lower kettle body, and the upper part of the lower stretching rod extends into the lower kettle body. Chucks are arranged at the opposite ends of the upper stretching rod and the lower stretching rod. The upperkettle body comprises an upper cavity provided with a first vertical through hole, an upper annular supporting piece, a first dynamic sealing structure, a second dynamic sealing structure and a lowerannular supporting piece, wherein the upper annular supporting piece and the first dynamic sealing structure are arranged between the middle part of the upper stretching rod and the first vertical through hole from top to bottom and the second dynamic sealing structure and the lower annular supporting piece are sequentially arranged between the lower part of the upper stretching rod and the lowerpart of the first vertical through hole from top to bottom. The test box has the characteristics of adjustable and controllable test temperature and high safety.

Description

technical field [0001] The invention relates to the technical field of high-pressure environment mechanics experiment equipment, in particular to a high-pressure environment mechanics experiment device capable of precisely controlling the experiment temperature. Background technique [0002] Hydrogen energy is an all-round energy source that provides electricity, heat and transportation fuel. [0003] The development of my country's hydrogen energy industry still faces the bottleneck of core technology and infrastructure constraints, and the lack of hydrogen energy infrastructure. According to incomplete statistics, there are 274 hydrogen refueling stations in operation worldwide. There are only 9 operational hydrogen refueling stations built in China. Among them, high cost and high technical requirements for hydrogen energy storage are the biggest obstacles to the construction of hydrogen refueling stations. my country's technology in core storage equipment such as proto...
