Abstract: The KM6 space environment simulator(named as the“KM6 chamber”), as an important large-scale test equipment for China′s manned space industry, has been in service for more than 20 years and has completed nearly 100 system-level vacuum thermal tests. The rough vacuum system is one of the most important components of the KM6 chamber.Its main function is to evacuate the KM6 chamber from atmospheric pressure to below 5Pa. In order to deeply understand the pressure change law in the roughing process, to provide a theoretical reference for the stable operation of the roughing system and subsequent upgrades, and to verify the applicability of CFX for the simulation analysis of the extraction process of large chambers, this article combines 5 sets of vacuum thermal test data in the experiment roughing process to analyze, and the pressure change law of each stage of the pumping process is given.

Key words: KM6, rough pumping unit, CFX, vacuum
