Regardless of any kind of equipment, everyone wants to choose a product with excellent quality, and the same is true for liquid nitrogen tanks. Then Bayu teaches you how to judge the quality of liquid nitrogen tanks.

Storage tanks are mainly used for static storage of indoor liquid nitrogen, and should not be used for long-distance transportation under working conditions; liquid nitrogen transport tanks have been specially designed for earthquake protection in order to meet the transportation conditions. In addition to being stored statically, it can also be used for transportation under the condition of filling liquid nitrogen, but it should also avoid severe collision and vibration.

Quality judgment:

1. During the use of the jar, the use of the jar should be checked every day. Under the premise of liquid nitrogen in the jar, it is found that there are water drops or frost on the top and the top of the jar, indicating that the quality of the jar is problematic. Stop using immediately;

2. When the bottle cap and the upper waterless beads or frosting phenomenon, touch the shell by hand, feel the upper part is cold, the lower part is hot, indicating that there are some problems with the quality of the jar, that is, the daily increase of liquid nitrogen is large, should pay attention to observation, After the loss of liquid nitrogen is prevented, the stored materials are damaged. If necessary, it is best to stop using them; if the upper and lower temperatures are the same, the quality of the cans is not problematic.

3. After opening the cork, the mist in the bottle mouth does not overflow, but sinks, indicating that the jar is good.

4. Use the ear to hear the sound of bubbles in the jar from the mouth of the bottle. If it is more frequent, there is a problem with the quality of the jar. Otherwise, there is no problem.
