What are the aspects of liquid nitrogen tank when filling liquid nitrogen

  Liquid nitrogen tank storage room to air circulation, such as in a closed room storage of more liquid nitrogen tank, the evaporation of nitrogen will stay in the room, resulting in hypoxia, there may be choking accident. Operation of liquid nitrogen cans to avoid the collision with other objects, because the liquid nitrogen tank by the exhaust and become a high degree of vacuum, inside and outside the tank by the atmosphere pressure is quite large, the operation should be very careful, must not be off Down or crash. Pchao liquid nitrogen tank technical personnel to remind the liquid nitrogen tank to keep vertical, is strictly prohibited pouring tank liquid nitrogen to avoid accidents.
  The initial filling of liquid nitrogen, or liquid nitrogen tank inside the dry state, the first check to see if there is no depression outside the tank or other abnormal circumstances. There is no foreign body in the tank, the base is really fixed. These conditions are good, you can start filling liquid nitrogen, and should be carried out in a well-ventilated place, generally in the outdoors. Such as in the room, must open the doors and windows to maintain a good ventilation and ventilation. Liquid nitrogen filling is a pressurized injection method, from the large liquid nitrogen container to open the liquid valve connected to the flexible hose, liquid nitrogen tank directly filled with liquid nitrogen. The other is a direct use of funnel pouring method, which should pay special attention to the funnel to make the end of the neck slightly away from the neck, so that the liquid nitrogen gas from the funnel and container clearance smoothly escape, otherwise the liquid from the funnel overflow , Will not only increase the _ liquid nitrogen loss, and will occur frostbite accident. Fill the liquid nitrogen speed to be slow, first into a small amount, and then pause for a few minutes to make it cool and then gradually fill enough to the specified capacity .
  Take the storage of fine hopper, you should first raise the bucket slightly, so that the bottom of the bucket to leave the base, then the bucket parallel to the central tank, go with the natural lift, the action should be quick and easy, can not use strong, Bend or break the handle, take the hopper should also pay attention to avoid touching the inner wall of the neck, so as not to damage the neck, handle to be divided into the circle, cover the cover to avoid running nitrogen.
  Liquid nitrogen replenishment cycle. What is the amount of liquid nitrogen to be reduced? In general, the liquid nitrogen residue is equal to half of the full capacity or only enough for one week to be added. To know the additional capacity, the liquid nitrogen cans on the scale weight measurement. A liter of liquid nitrogen weight of 0.8 kg plus the weight of the tank can be obtained when the weight of the full tank, minus the existing weighing, that is, should be added capacity. For the sake of simplicity, a fine stick can be inserted into the liquid nitrogen for a few seconds, the stick quickly removed in the air shaking a few times, insert the liquid nitrogen part of the low temperature and white frost, it is easy to detect the tank Liquid nitrogen stock.
  When the vehicle is transported and transported, the liquid nitrogen is followed by oscillation due to the vibration of the vehicle, thereby increasing the consumption. The rate of consumption increases, depending on the shape of the container, such as a 10 liter liquid nitrogen tank, the daily delivery time of eight hours, the consumption of about 100 grams (including 0.12 liters) at the same time as the operation of the handle is also increased consumption, Such as a 10L each operation will consume about 10 grams, in order to reduce the activity of storage and safe transport, liquid nitrogen tank to do coat or wooden luggage, especially on the way to prevent the liquid nitrogen tank reversed, so as to avoid accidents.
  Liquid nitrogen tank internal washing and drying: liquid nitrogen tank in the process, the accumulation of moisture inside. And mixed with bacteria, may also fall into the handle, and from the handle out of the semen mixed in liquid nitrogen inside. Liquid nitrogen is an inert substance, the container is not corroded inside, due to the above reasons, sometimes there may be a considerable degree of corrosion, if mixed with bacteria, artificial insemination of the conception rate will be reduced.
  Therefore, the annual liquid nitrogen tank to be cleaned and dried 1 a 2 times, the steps are: ① remove the handle from the container and liquid nitrogen, placed about two days. So that the internal temperature of the container rises to. ° C. ② with 40 ℃ a 50 ℃ warm water or with a neutral detergent into the liquid nitrogen tank, and then scrub with a cloth. ③ rinse with water. ④ reverse the container to dry. Drying method can be used natural dry method or hot air drying method. If the latter, the temperature limit of 40 ℃ a 50 ℃, should avoid more than 60 ℃ hot air, so as not to affect the performance of liquid nitrogen tank, shorten the service life.
