静置时间和充满率对静态蒸发率的影响

Influence of Standing Time and Filling Rate on Static Evaporation Rate

静态蒸发率受环境温度、压力、静置时间和充满率的影响。实验研究了静置时间对卧式低温绝热气瓶的影响,及充满率对立式低温绝热气瓶和卧式低温绝热气瓶的影响,并基于不同的充满率对卧式低温绝热气瓶静态蒸发率进行修正。研究表明:当静置时间大于12 h,静态蒸发率随静置时间的增大而减小;静置时间小于12 h,静态蒸发率随静置时间的增大无规律变化。静态蒸发率随着充满率的减小而减小。

The static evaporation rate was influenced by the ambient temperature, pressure, standing time and filling rate. The influence of the standing time on the horizontal cryogenic insulation cylinders and the filling rate on the horizontal and vertical cryogenic insulation cylinders were studied. Based on the different filling rate, the static evaporation rate of the horizontal cryogenic insulation cylinders was corrected. The results showed that when the standing time was more than 12 h, the static evaporation rate decreased with the increase of the standing time, the standing time was less than 12 h, the static evaporation rate changed irregularly with the increase of the standing time. The static evaporation rate decreased with the decrease of the filling rate.
