Working principle of self-pressurization system
Liquid oxygen vaporization: Part of the liquid oxygen in the tank is directed to the booster, which is usually a tubular heat exchanger or coil structure. By absorbing heat from the outside, the liquid oxygen begins to vaporize and turns into oxygen gas.

Gas reflux pressurization: The vaporized oxygen gas is transported back to the gas phase space of the tank. This part of the gas occupies the gas phase volume inside the tank, thereby increasing the pressure inside the tank.
