The invention discloses a liquid carbon dioxide filling system and method for aerospace products, carbon dioxide is used as a working medium, a booster pump special for liquid carbon dioxide is used for pressurizing liquid carbon dioxide in a Dewar tank into a piston energy accumulator, and the piston energy accumulator is used for ensuring that the pressure at the rear end of the booster pump is stable; and the piston is pushed by extruding gas to extrude the liquid carbon dioxide into the storage tank. The liquid carbon dioxide filling device overcomes the unstable influence caused by supercritical characteristics, is stable in output pressure, long in service life, safe, free of pollution, good in maintainability, portable, movable and reusable, and is suitable for filling liquid carbon dioxide of spaceflight products.

    本发明公开了一种航天产品的液态二氧化碳加注系统及加注方法,利用二氧化碳作为工质,采用液体二氧化碳专用的增压泵将杜瓦罐中的液态二氧化碳增压至活塞蓄能器中,通过活塞蓄能器来保证增压泵后端压力稳定,再通过挤压气体推动活塞挤压液态二氧化碳进入贮箱。克服了其超临界特性带来的不稳定影响,输出压力稳定,使用寿命长,安全无污染,维修性好,便携式可移动,可重复利用性,适用于航天产品液态二氧化碳的加注。
