Liquid nitrogen supply tank is an important equipment for storing and supplying liquid nitrogen, which has a wide range of applications in various fields such as biomedicine, food freezing, animal husbandry, etc. Proper use of liquid nitrogen supply tanks can not only ensure smooth operations, but also ensure the safety of personnel and equipment.

Before use, carefully inspect the appearance of the supply tank for rust, dents, or damage, especially paying attention to whether the valve and pipeline connections are loose or leaking. After confirming that the tank is intact, place it in a stable and well ventilated place, away from sources of fire, heat, and densely populated areas, with no obstacles blocking operation and heat dissipation in the surrounding area.

openLiquid nitrogen supply tankWhen operating, the action should be slow and gentle. First, turn the main valve to the open position, and then gradually adjust the pressure reducing valve to achieve the desired output pressure. It is strictly prohibited to open quickly or operate violently to prevent sudden changes in internal pressure from causing liquid nitrogen splashing or equipment damage. During use, closely monitor the changes in the pressure gauge values to ensure that the pressure remains stable within a safe range. If any abnormal fluctuations occur, immediately stop using and investigate the cause.

When transporting liquid nitrogen, specialized low-temperature pipelines or hoses should be used to ensure tight connections, no leaks, and to avoid skin contact with liquid nitrogen, as its extremely low temperature (-196 ℃) can instantly cause frostbite. If you accidentally come into contact with liquid nitrogen, quickly rinse the affected area with plenty of water and seek medical attention promptly.

During the storage period of the liquid nitrogen supply tank, the liquid level should be checked regularly. When the remaining liquid nitrogen is insufficient, it should be refilled in a timely manner. However, the refilling process should also strictly follow the operating procedures to prevent liquid nitrogen overflow. When not in use for a long time, all valves should be closed to release internal pressure, and the tank should be cleaned and maintained for proper storage.

After use, close the outlet valve first, then close the main valve to allow the residual pressure in the tank to naturally release. Finally, remove the relevant connecting pipelines, clean and record the equipment, and provide reference for subsequent use.

In short, the use of liquid nitrogen supply tanks involves multiple key links, and each step cannot be taken lightly. Only by strictly following the operating procedures can their functions be fully utilized, safety accidents be avoided, equipment service life be extended, and various scientific research and production activities be safeguarded.
