First, the liquid nitrogen tank placed
Liquid nitrogen tank to be stored in a well-ventilated shade, do not direct sunlight in the sun. Because of its manufacturing precision and its inherent characteristics, both in the use or storage, the liquid nitrogen tank are not allowed to tilt, horizontal, inverted, stacking, collision or collision with other objects, to do lightly and always keep upright.
Second, liquid nitrogen tank cleaning
Liquid nitrogen tank idle when not in use, rinse with water, the water row net, with a blower dry, placed at room temperature stand-by. Liquid nitrogen tank liquid nitrogen after evaporation, the remaining missing substances (such as frozen sperm) quickly melt into a liquid material attached to the liner, the aluminum alloy will cause corrosion, if the formation of empty, liquid Nitrogen cans must be scrapped, so the liquid nitrogen tank after the liquid nitrogen depleted after the brush is very necessary to the specific brushing method is as follows: First, the liquid nitrogen tank to remove the cylinder, liquid nitrogen removed, placed 2-3 days, The temperature inside the tank to rise to 0 ℃ or so, and then poured about 30 ℃ warm water, scrub with a cloth. If you find that individual melting substances stick to the bottom of the liner, be sure to carefully wash clean. And then rinse with water several times, then inverted liquid nitrogen cans, on the indoor safety should not be overturned, naturally dry, or as previously described with a blower air-dried. Note that the entire scrub process, the action should be slow, into the water temperature can not exceed 40 ℃, the total weight of not more than 2 kg is appropriate.
Third, the safe transport of liquid nitrogen tank
Liquid nitrogen tank in the transport process must be installed in the wooden mat mattress, and fixed. Between the tank and the tank to use the filler separated to prevent bumps, to prevent dumping. Loading and unloading vehicles to prevent liquid nitrogen tank hit, but can not drag on the ground at random, so as to avoid the life of liquid nitrogen tank.
