Abstract: Mars has always been considered the most likely place in the solar system where life outside of Earth has flourished and survived to this day. Therefore, the simulation of its surface environment plays an important role in the study of Mars. Based on the requirements of the Mars dust chamber system project of XX university's space simulation device, a system is designed to simulate the low-pressure environment on the surface of Mars. A vacuum pump group is used to reduce the pressure inside the Mars dust chamber, and a pneumatic regulating valve is used for high-precision dynamic pressure regulation to maintain stable pressure inside the Mars dust chamber. The system design technical parameters, system composition, working conditions and pumping speed calculation process are introduced in detail.

Key words: Mars, surface environment simulation, low-pressure environment, vacuum, regulating valve
