Liquid nitrogen tank is a specialized equipment used for storing and transporting liquid nitrogen gas, widely used in scientific research, medical, industrial and other fields. Liquid nitrogen itself has an extremely low temperature (-196 ° C), so it is crucial to ensure its safety and efficiency when using liquid nitrogen tanks. The following is a guide for using liquid nitrogen tanks to help users understand how to operate correctly and ensure the long-term safe operation of the equipment.

1. Proper operation of liquid nitrogen tank
The use of liquid nitrogen tanks should follow strict operating procedures. Firstly, operators must undergo professional training to understand the working principle, safety requirements, and emergency response measures of liquid nitrogen tanks. When using, ensure that there are no leaks at the valves and interfaces of the tank, and regularly check the integrity and insulation performance of the tank.

Usage steps:

Add liquid nitrogen: Use specialized tools for liquid addition operations to avoid direct contact with liquid nitrogen and prevent frostbite. When adding liquid, ensure good ventilation in the operating environment to avoid gas accumulation during liquid nitrogen evaporation.

Storage and transportation: During storage and transportation, liquid nitrogen tanks should be placed in a stable environment to avoid severe vibration or impact. During transportation, the liquid nitrogen tank should be fixed on a dedicated bracket to ensure its stability.

2. Regular inspection and maintenance
The long-term safe operation of liquid nitrogen tanks requires regular inspection and maintenance. Before each use, check the sealing of the liquid nitrogen tank, whether the valves and pipelines are intact. Especially for the vacuum insulation performance of liquid nitrogen tanks, if frost or cooling is found on the surface of the tank, it may indicate a decrease in the performance of the vacuum layer and should be repaired in a timely manner.

Common inspection items:

Valve inspection: Ensure that the valve operates normally and is not loose or leaking.

Temperature and pressure monitoring: Regularly monitor the internal temperature and pressure of the liquid nitrogen tank to ensure that the equipment operates within a safe range.

External cleaning: Clean the dust and stains on the surface of the tank to observe for cracks or damage.
