The invention discloses a high-reliability long-life compensator for thermal control of a spacecraft and a preparation method, and relates to the field of space temperature control fluid loop compensators, the high-reliability long-life compensator comprises a storage box body, an upper cover and a corrugated pipe assembly, the upper cover is welded to one end of the storage box body, the corrugated pipe assembly is welded to the other end of the storage box body, and the corrugated pipe assembly is located in the storage box body; the corrugated pipe assembly is used for being connected with a thermal control fluid loop, a liquid cavity is formed in the corrugated pipe assembly and communicated with the thermal control fluid loop, and an air cavity is formed between the corrugated pipe assembly and the storage box body. The main function is to reduce pressure fluctuation of a fluid loop, prevent cavitation caused by too low inlet pressure of a loop pump, and compensate liquid working medium reduction caused by long-term operation, maintenance and micro-leakage of a system. The product provided with the liquid level sensor also has a liquid level display function.
本申请公开了一种航天器热控用高可靠性长寿命补偿器及制备方法,涉及空间温控流体回路补偿器的领域,包括贮箱体、上盖、波纹管组件,上盖焊接连接于贮箱体的一端,波纹管组件焊接连接于贮箱体的另一端,波纹管组件位于贮箱体内部,波纹管组件用于连接热控流体回路,波纹管组件内形成液腔,液腔与热控流体回路连通,波纹管组件与贮箱体之间形成气腔。其主要功能是减小流体回路压力波动,防止回路泵入口压力过低产生汽蚀,补偿系统长期运行、检修和微漏导致的液体工质减少。安装了液位传感器的产品还具备液位显示功能。
