Cleaning of gas-phase liquid nitrogen tank
   When the gas-phase liquid nitrogen tank is not in use, rinse it with clean water, drain the water, blow it dry with a blower, and place it at room temperature for later use. After the liquid nitrogen in the liquid nitrogen tank is volatilized, the remaining missing substances (such as frozen sperm) quickly melt and become liquid substances attached to the inner tank, which will corrode the aluminum alloy inner tank. If a cavity is formed, the liquid The nitrogen tank must be scrapped, so it is necessary to scrub the tank after the liquid nitrogen in the liquid nitrogen tank is exhausted. The specific scrubbing method is as follows: first take out the lifting cylinder from the liquid nitrogen tank, remove the liquid nitrogen, and leave it for 2-3 days. After the temperature in the tank rises to about 0°C, pour in warm water of about 30°C and scrub with a cloth. If you find that some melted substances stick to the bottom of the inner tank, you must carefully wash it off. Then rinse it with clean water several times, then turn the liquid nitrogen tank upside down, place it indoors where it is not safe to tip over, let it dry naturally, or use a blower as described above. Note that during the entire scrubbing process, the action should be light and slow, the temperature of the poured water should not exceed 40°C, and the total weight should not exceed 2kg.
  The safe transportation of gas-phase liquid nitrogen tank
  The gas-phase liquid nitrogen tank must be installed in a wooden frame with soft cushions and fixed during transportation. Filling should be used to separate the tank from the tank to prevent bumps and bumps and prevent dumping. When loading and unloading the truck, it is necessary to prevent the liquid nitrogen tank from colliding, and not to drag it on the ground at will, so as not to reduce the service life of the liquid nitrogen tank.
