Characteristics of cryogenic liquid oxygen storage tanks
Date: Nov 12, 2019
On May 17, the first 80-ton liquid-oxygen methane rocket engine in China was successfully commissioned. It is the world's third-largest thrust liquid oxygen methane engine. It is also the world's largest thrust cryogenic liquid rocket engine, which means that China's private space force is the first to master. The key technology of the 100-ton liquid rocket engine and the support capability required for engine development.
Liquid oxygen has a strong combustion-supporting property in modern industrial applications and military applications, but if there is a mixture of combustible materials (including gas, liquid, solid) and liquid oxygen, there is an explosion hazard. This mixture is often due to static electricity. Mechanical impact, electric sparks, and the like, especially when the mixture is solidified, can often explode.
In addition, when liquid oxygen is accumulated in the closed system, if it cannot be kept warm, pressure damage may occur. When the temperature rises to -118.4 °C without increasing the pressure, the liquid oxygen cannot maintain the liquid state, and if the pressure is not timely, Will cause a physical explosion.
Therefore, liquid oxygen must be stored in a liquid state under a standard low temperature pressure storage tank, commonly known as liquid oxygen storage tanks, vertical liquid oxygen storage tanks and horizontal liquid oxygen storage tanks. (In addition to conventional products, the Jianshen company can also customize cryogenic liquid storage tanks of various volume and pressure grades.)
The storage tanks are double-layered tanks, vacuum pearl sands are insulated and filled; all welds of the inner and outer containers are carried out. Detection, good thermal insulation performance, low evaporation loss, long service life; high quality epoxy rich new primer topcoat to ensure a more beautiful appearance and longer corrosion life; compact tank structure, advanced piping and process design, operation It is simpler and safer, and maintenance is more convenient.
