According to the main purpose, there are two types of liquid nitrogen containers: storage and replenishment!
The liquid storage is a conventional liquid nitrogen container, which is open without pressure; the liquid replacement is a pressurized transfer container, and the “closed” has working pressure!
The reason why it is called “working pressure” is that there is no pressure in the pure storage state of the liquid nitrogen transfer container, and only the output of liquid nitrogen needs to be boosted. In addition, attention should be paid to the boosted value, which is within a certain range!
Let’s talk about the range first, the preferred range detected by Tianchi is 0.05~0.09MPa!
When ≥0.05MPa, ≤0.09MPa, the infusion speed is guaranteed, and there is no need to worry about safety!
The exact amount of pressurization depends on individual needs!
If only a small amount of liquid nitrogen is transported, the liquid can be discharged at a pressure of 0.02MPa, but the transport is not continuous;
If you want continuous and uninterrupted rehydration and save liquid nitrogen, then = 0.05MPa;
The required speed is >0.05MPa, just adjust the booster valve according to the desired speed!
But note that the pressurization should not exceed 0.09Mpa. When it exceeds, the safety valve will automatically open to discharge excess pressure to prevent the risk of explosion. In addition, excessive pressure will also cause unnecessary waste of liquid nitrogen.
Now, do you know how much pressurization is required to output liquid nitrogen from the liquid nitrogen transfer container?
