The following matters should be kept in mind to avoid "adverse reactions" when using liquid argon tank for the first time.
I. Inspection of liquid argon storage tank before use
When liquid argon storage tank is filled with liquid argon, the first thing is to check whether the shell is sunken and whether the vacuum exhaust port is intact. If it is damaged, the vacuum degree will be reduced, serious intake can not be insulated, so that the upper part of the tank will frost, liquid argon loss, lose the value of continued use.
Two, liquid argon filling
Be careful when filling liquid argon. For new tanks or tanks in dry state, slow filling and pre-cooling should be carried out to prevent the tank from being damaged too quickly during cooling and reduce the service life. When filling liquid argon, please do not pour liquid argon on the vacuum vent to avoid the decrease of vacuum degree.
Storage capacity of liquid argon in liquid argon storage tank
When the liquid medium is stored in the liquid argon tank, be sure to close the inlet/discharge valve and the booster valve, and open the vent valve.
Iv. Transportation of liquid argon in liquid argon storage tank
When the liquid argon tank is transporting the infusion argon medium, it is necessary to ensure that the switching state of each valve should be the same as that in storage, and the base of the packing box should be placed under the container seat circle, and the liquid argon tank container should be reliably fixed on the car with ropes, so that the liquid argon tank will not shake during transportation.
V. Liquid argon infusion in liquid argon tank
Close the vent valve; Open the pressure valve; Observe the pressure gauge; When the pressure rises to 0.05MPa(0.5kg/cm2), open the drain valve, that is, continuous infusion.
Vi. Check in the process of use
Check frequently during use. You can observe the shell with your eyes or touch it with your hands. If frost is found on the surface, the Hebei Liquid argon storage tank should be stopped. In particular, it is not appropriate to scrape the inner wall of the cervical tube with a knife when the frost freezes, so as to prevent the inner wall of the cervical tube from being damaged and resulting in poor vacuum. Instead, the liquid argon should be removed and let it melt naturally.
