The device comprises a helium tank, a helium valve, a xenon gas storage tank, an air source valve, a vacuum valve, a vacuum pump, a transfer valve, a transfer air cylinder, a transfer air cylinder electronic scale, a data acquisition system, a purity analyzer, a filling valve, a temperature-control device, a recycle valve, a recycle module, a liquid nitrogen valve, a liquid nitrogen tank and an air vent valve. The invention provides a method for testing the PVT properties of the high-purity xenon gas in the closed container through research. By utilizing the method, a verification test for the PVT properties of the high-purity xenon gas is finished, so that the method is reasonable and feasible. When the PVT properties of xenon gas in the closed container is obtained and physical property test data of xenon gas is accumulated, an excellent foundation is laid for following xenon gas engineering application.

Description

technical field [0001] The invention relates to a PVT property testing device and method for high-purity xenon gas used in a satellite electric propulsion system, and belongs to the technical field of high-purity xenon gas physical characteristic testing. Background technique [0002] At present, there are many types of propulsion systems for in-orbit flight. Among them, the electric propulsion system has developed rapidly in recent years due to its high specific impulse, especially the Hall electric propulsion system and ion electric propulsion system, which are often used in geostationary orbits The satellite platform performs tasks such as north-south position keeping, attitude control (momentum wheel unloading), orbit control, and even synchronous orbit transfer. In addition, electric propulsion systems can accomplish tasks that conventional propulsion systems cannot, such as deep space exploration, interstellar travel and other tasks that require large Δy, as well as ta...
