Proper use of liquid oxygen storage tanks
Before using liquid oxygen storage tanks, a small amount of liquid nitrogen should be put in to pre-cool it.
1. Before using liquid oxygen storage tanks, a small amount of liquid nitrogen should be put in to pre-cool it. When the temperature in the tank reaches the liquid nitrogen temperature, fill the liquid nitrogen tank with liquid nitrogen. Pay attention to handling the liquid nitrogen tank with care to avoid collision and squeezing, and do not lift it when dragging it on the ground. When not in use, liquid nitrogen tanks should be stored in a dry, well-ventilated room to prevent moisture.
2. Check the neck plug and the small groove of the neck plug at any time, remove the ice on the neck plug in a timely manner, and do not place plastic sheets or other materials on the neck plug to increase the sealing performance and ensure the performance of the liquid nitrogen tank. When it is found that the liquid nitrogen consumption is too fast or there are water droplets and hoarfrost near the neck of the liquid nitrogen tank, it means that the insulation function of the tank is out of balance and the liquid nitrogen cannot be retained. The storage tanks must be well marked, and the storage tanks must be picked up and placed steadily, accurately, and quickly.
3. In order to prevent erosion of the tank wall, the inner cavity of the liquid nitrogen tank needs to be cleaned once a year. In addition, attention should be paid to minimizing the transportation of liquid nitrogen tanks and reducing the number of times the liquid nitrogen tanks are opened. If it needs to be transported, it must be fixed to the carriage with ropes to keep the liquid nitrogen tank upright. Prevent falls, overturning, and lying down, and try to avoid severe vibrations.
