Problems in the use of liquid nitrogen tanks

Cryogenic liquid nitrogen storage tanks are widely used in scientific research, physics, medicine, biological engineering, chemical industry, food, metallurgy, petroleum, storage batteries, wood-based panels and other fields. Provide users with high-precision, controlled, ultra-low temperature environment with uniform temperature, ideal research and development equipment for testing and chemical analysis research departments, colleges and universities, factory laboratories and metrology and quality inspection departments.
 
Liquid nitrogen refrigeration and high-precision intelligent instruments are used to control ultra-low temperature, and the principle of heat balance and circulation stirring method is used to achieve automatic uniform cooling and constant temperature of the sample. The equipment is equipped with a high-quality stainless steel large freezer, which has a large cooling capacity, corrosion resistance, aging resistance and beautiful appearance. Automatic temperature control, automatic timekeeping, automatic alarm, easy and safe operation, high work efficiency, fast cooling speed, large volume and high temperature control accuracy. There are two types of liquid nitrogen storage tanks: storage tanks and transport tanks. Storage tanks are used for indoor storage and are not easy to transport over long distances. Transport tanks are used for transportation. The following problems need to be paid attention to when using liquid nitrogen storage tanks:
 
Cryogenic liquid nitrogen storage tanks should be stored in a well-ventilated and shady place, isolated from fire sources and heat sources, and should not be exposed to the sun. Always check the tightness of the storage tanks, and do not tilt, stand upside down, place them sideways, and pile up. When storing liquid medium in the liquid nitrogen tank, be sure to close the inlet / outlet valve and booster valve, and open the vent valve.
 
During the transportation process, it is necessary to ensure that the switching state and storage of each valve are consistent, and a cushion pad is arranged below to securely. When in use, check the outside of the cryogenic liquid nitrogen tank. If frost is found, you must stop using it immediately to troubleshoot.
