摘要
静态真空是星载斯特林制冷机在地面进行各项性能试验的必备条件,它主要由杜瓦和真空保持系统组成。主要介绍斯特林制冷机杜瓦和真空抽气系统的设计。通过试验证明,该系统能够满足斯特林制冷机进行性能试验所需的真空条件。
The permanent vacuum is essential condition of the spaceborne Stirling cryocooler which various performance experiments on the ground. It consists of dewar flask and facility that keeps the vacuum constitutes, The design of dewar flask and pump system are introduced, it has been verified that the system can satisfy the vacuum condition of Stirling cryocooler test.
