Abstract

The invention provides a vacuum system for simulating a large dust distribution environment of the moon. A rough pumping system of the vacuum system is responsible for completing rough pumping of a container and establishing an initial basic vacuum environment; a low-temperature pump main pumping system of the high-vacuum unit is used for establishing and maintaining test pressure; a molecular pump auxiliary pumping system is used for auxiliary pumping of the cryopump and also serves as a leak detection system of the equipment; and a re-pressing system is used for recovering the vacuum environment in the vacuum container to the atmospheric environment, the vacuum valve system comprises a plurality of valves used for connecting and disconnecting a gas path, and the pipeline system comprises an exhaust pipeline, a water path system and a gas path system. The technical problem of how to design a set of vacuum system which is suitable for preventing dust particles from splashing and pollution under the condition of large cloth dust is solved. The system provides a vacuum environment for the lunar surface comprehensive environment simulator to carry out lunar surface multi-factor comprehensive environment effect tests such as vacuum, low temperature, electron irradiation, ultraviolet irradiation, X-ray irradiation, micron/submicron charged dust and the like.

Description

technical field [0001] The invention relates to a vacuum system for simulating a large dust environment on the moon, and belongs to the technical field of space environment simulation. Background technique [0002] There is no atmosphere on the surface of the moon, and it is in a high vacuum state, and the surface of the moon has soft lunar soil and charged moon dust at the micro-nano scale. When we simulate the comprehensive environment of the lunar surface on the ground, we must simulate the lunar soil and moon dust environment on the lunar surface. , but also to simulate the vacuum environment to form a multi-factor environmental simulator of a table. The key point of the lunar environment simulation device is to design a vacuum system that can be used in a large dust environment (30kg moon dust or 500kg moon soil). Its function is to generate a vacuum environment in the vacuum container of the lunar environment simulator without destroying the container. Simulation of o...
