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.

    本发明提出一种用于模拟月球大布尘环境的真空系统,该真空系统的粗抽系统负责完成容器粗抽,建立最初的基本真空环境;高真空机组的低温泵主抽系统用于试验压力的建立和维持;分子泵辅抽系统用于低温泵辅助抽气,还作为设备的检漏系统;复压系统用于将真空容器内的真空环境恢复到大气环境,真空阀门系统包括若干阀门用于导通和切断气路,管道系统包括排气管道、水路系统和气路系统。解决了如何设计一套适用于大布尘条件下的防粉尘颗粒飞溅与污染的真空系统的技术问题,本发明为月表综合环境模拟器开展真空、低温、电子辐照、紫外辐照、X射线辐照、微米/亚微米级带电粉尘等月表多因素综合环境效应试验提供真空环境。
