How Liquid Oxygen Tanks Work
The working principle of liquid oxygen tanks is a complex and delicate process involving multiple steps.
The working principle of liquid oxygen tanks is a complex and delicate process involving multiple steps. First, oxygen is gaseous at normal temperature and pressure. Through the process of compression and cooling, oxygen is converted into liquid oxygen (LOX). This process is usually completed in a dedicated liquefaction device, and the temperature is reduced to about -183 degrees Celsius to convert oxygen into liquid.
When storing liquid oxygen, special attention should be paid to its temperature and pressure. Liquid oxygen tanks are usually made of insulating materials to ensure a low temperature environment and reduce the evaporation and pressure increase of liquid oxygen. These tanks must not only be designed to withstand low temperatures, but also have good sealing properties to prevent oxygen leakage.
When liquid oxygen is needed, the liquid oxygen in the tank is converted into a gaseous state by heating or releasing pressure. This process usually involves a vaporizer to ensure that the gaseous oxygen is supplied to the device at the appropriate flow rate and pressure.
Because liquid oxygen is highly oxidizing, any risk of contact with fire or flammable substances is extremely high, so the tank is equipped with a variety of safety devices, including pressure relief valves, temperature monitoring systems, etc., to ensure safe operation under various working conditions. These safety measures are particularly important in applications in aerospace, medical, industrial and other fields to prevent accidents.
