Frequently Asked Questions
What industry standards do these vacuum chambers comply with?
The equipment meets multiple rigorous standards including GB/T 32221-2015, GB/T 34522-2017, and military standards such as GJB 3758-1999 and GJB 1033A-2005 for spacecraft thermal vacuum testing.
What is the achievable temperature range for testing?
Both the heat sink and the mounting plate can operate within a wide temperature range of -70℃ to +150℃, with an average change rate of ≥2℃/min.
What level of vacuum pressure can the system maintain?
The system achieves an ultimate pressure of ≤5x10⁻⁵Pa and maintains a working pressure of ≤1.3x10⁻³Pa, utilizing a high-efficiency cryogenic pump system.
What are the cooling and heating specifications?
The system utilizes mechanical cascade refrigeration and water cooling methods. Depending on the model, heating power ranges from 18kw to 30kw to ensure rapid thermal transitions.
How is the temperature uniformity ensured?
For smaller models (HY-810 to HY-1012), temperature uniformity is maintained at ±2℃. For larger models (HY-1214 to HY-1216), it is maintained at ±3℃.
What is the typical pumping time for the main vacuum system?
The main pump pumping time for these TVAC chambers is approximately 5 hours to reach the required testing environment.
