Vacuum pumps play a vital role in aerospace training and simulation environments, and their application value is reflected in several key areas:

1.Spacecraft simulation vacuum test: In the development and testing stage of spacecraft, vacuum pumps are used to simulate low-pressure, low-temperature and high-vacuum environments in space to ensure that the reliability and functionality of the spacecraft are fully verified.

2.Propulsion System Testing: Vacuum pumps are essential for the testing of aerospace propulsion systems, creating the necessary vacuum conditions to evaluate the performance and stability of the propulsion system in a vacuum.

3.Fuel supply system: In a vacuum environment, vacuum pumps are used to extract gas from fuel storage containers to ensure that the fuel can be delivered efficiently and safely to the designated location.

4.Cabin environment control: In the cabin of aircraft and spacecraft, vacuum pumps help maintain appropriate air pressure and gas composition, providing a stable and safe living and working environment for astronauts.

5.Aero Engine Testing: Vacuum pumps play an important role in the development and testing of aero engines, simulating the working environment of the engine when flying at high altitudes to ensure the performance and reliability of the engine.

6.Thermal vacuum environment simulation: Vacuum pumps are used to reproduce the vacuum environment, external heat flow environment, and cold and dark environment in space, which is essential for performance testing of spacecraft and other exploration equipment.

Vacuum pumps provide critical simulation conditions for space exploration, ensuring that spacecraft and related equipment can be effectively tested and validated in a simulated space environment, thereby improving the success rate and safety of space missions.
