摘要
对低温储罐真空度的绝热性能进行研究。通过讨论影响低温储罐真空度的因素、真空度的检验内容和判定方法,以及两种不同的抽真空工艺,本文对抽真空时间、日漏放气率、冷态真空度和日蒸发率等进行了分析。
The paper conducts the research on thermal insulation performance of vacuum degree in cryogenic tanks. It analyzes the vacuum extraction time, diurnal leakage rate, the vacuum of cold state and the rate of daily evaporation by discussing the factors affecting vacuum degree in cryogenic tanks, inspection contents and judgment method of vacuum degree, as well as two different vacuum extraction processes.
