The invention relates to a low-temperature vessel and vaporizer self-pressurization system and method. The system comprises low-temperature vessels, low-temperature stop valves, a low-temperature filter, a plunger pump, a low-temperature safety valve, a vaporizer, a temperature sensor, a low-temperature liquid pipeline, an outlet pipeline and a pressurized gas pipeline. One end of the low-temperature liquid pipeline is connected to the lower ends of the low-temperature vessels, and the other end of the low-temperature liquid pipeline is connected to an inlet of the plunger pump. The corresponding low-temperature stop valve, the low-temperature filter and the plunger pump are sequentially connected to the low-temperature liquid pipeline in series, and the corresponding low-temperature stop valve is located between the low-temperature filter and the low-temperature vessels. An outlet pipeline is further connected to an outlet of the plunger pump, the other end of the outlet pipeline is connected with the vapori
