VACUUM/PRESSURE SYSTEM APPLIED IN SPACE EXPERIMENT PROJECTS

Vacuum/pressure system is used to ensure an experiment environment for alternation of positive pressure and negative pressure for the experiment chamber. The experiment process contains two operating states,positive pressure and negative pressure,with advantages of high integration and compact conformation. The system makes a full use of vacuum and microgravity environment,it reduces the system complexity,increases the reliability,saves the space resource and in-orbit operation cost.
