Vacuuming the liquid argon tank
The process of evacuating a liquid argon storage tank involves multiple steps and technical requirements to ensure that the interior reaches a certain level of vacuum, thereby maintaining its insulating properties and safety.
The process of evacuating a liquid argon storage tank involves multiple steps and technical requirements to ensure that the interior reaches a certain level of vacuum, thereby maintaining its insulating properties and safety.
Liquid argon storage tanks typically feature a double-layer structure, with an inner container and an outer container. The space between these two layers is filled with insulating material (such as perlite) and evacuated. This design effectively reduces heat conduction, maintaining the low temperature of liquid argon.
Before evacuating a liquid argon storage tank, it is essential to check the current vacuum level to determine whether evacuation is needed and to what extent. A professional vacuum pump system is used to re-evacuate the tank’s interlayer to achieve the desired vacuum level.
