A brief overview of the design of the “Pujiang One” satellite fluid circuit system and ground test conditions are given. On this basis, the open-loop and closed-loop control tests of the fluid circuit system in-orbit are introduced in detail. And micro-pump B long-life test. The in-orbit test results show that the components of the micro pump-driven fluid circuit system meet the requirements of the space environment; the performance of the system software and hardware on-orbit is stable and long-term; the fluid circuit system can quickly collect and transmit the heat of the spacecraft, Thermal management capabilities.
