Jinfeng liquid nitrogen tank instructions
Jinfeng liquid nitrogen tank is the leader in domestic liquid nitrogen tanks , and is also the preferred brand of most users. How should Jinfeng liquid nitrogen tanks be used? The following will be explained by the Shanghai Bayu technical staff for the use of Jinfeng liquid nitrogen tank.
Jinfeng liquid nitrogen tank instructions:
1. Before using the Jinfeng liquid nitrogen tank, it should be filled with a few liters of liquid nitrogen for cooling. After the cooling is successful, it will be filled again. If it is directly filled, the temperature inside the liquid nitrogen tank is too high, and there is a large amount of liquid nitrogen vaporized. The nitrogen gas causes the liquid nitrogen to not be completely filled.
2. After you have filled the liquid nitrogen tank, in the first week, you should use the liquid nitrogen meter to check the residual amount of liquid nitrogen in the liquid nitrogen tank to prevent the liquid nitrogen tank from causing liquid nitrogen tank due to the collision during the transportation. The damage is then checked once a week. After one month, it is checked once a month. After three months, it is checked every three months. If you open the lid frequently, please pay attention to replenish liquid nitrogen in time.
3 , every 1 liter of liquid nitrogen can become 700 liters of nitrogen, so the liquid nitrogen tank can not be sealed, otherwise, the liquid nitrogen tank will be a small bomb, so it is normal for the liquid nitrogen tank to see white fog.
4 , liquid nitrogen tank should be used in a dry and ventilated room. When using a liquid nitrogen tank, the lid of the liquid nitrogen tank should be placed back, that is, the rubber plug of the lid is vertically below, the blue lid is on, standing, preventing the water from being sucked back into the lid, causing the lid of the liquid nitrogen tank to freeze in the liquid nitrogen tank. mouth. If the water vapor in the room is too large, causing ice to form on the lid of the liquid nitrogen tank, please expose it to sunlight.
5. If the lid of the liquid nitrogen tank is frozen on the liquid nitrogen tank, use a small hammer to gently hit the bottle mouth, and then put the liquid nitrogen tank lid on the liquid nitrogen tank.
6. After you get the liquid nitrogen tank, you will see a small raised lid on the mouth. Do not move it. It is the vacuum seal of the liquid nitrogen tank. If the vacuum port (equivalent to the vacuum flask) If the vacuum tip is broken, it will cause the vacuum of the liquid nitrogen tank to be destroyed, resulting in the scrapping of the liquid nitrogen tank.
Jinfeng liquid nitrogen tank use precautions:
1. Liquid nitrogen tanks are only used to store liquid nitrogen and do not store other liquids;
2. Check whether the inside of the container is clean and dry before use;
3. Pre-cooling with a small amount of liquid nitrogen before filling with liquid nitrogen;
4. For long-term storage, it is necessary to replenish liquid nitrogen regularly. The timing of replenishment should generally be one third of the total capacity of liquid nitrogen.
5. It is strictly forbidden to place objects on the container cover and seal the neck opening;
6. When putting in or taking out frozen articles, try to make the opening time of the tank opening as short as possible to reduce the consumption of liquid nitrogen, and do not put the lifting cylinder completely;
7. Strictly prevent shocks and collisions;
8. It is strictly forbidden to remove the frost in the neck tube with a hard object to avoid damage to the neck tube.
Jinfeng liquid nitrogen tank cleaning method:
First, the liquid nitrogen tank Canisters removed liquid nitrogen is removed, placed 2--3 days, the liquid nitrogen tank until the temperature rises to about 0 deg.] C, then poured in warm water about 30 ℃, scrub with a cloth. If you find that the individual melted substances are stuck on the bottom of the inner liner, be careful to wash them carefully. Then rinse with water several times, then invert the liquid nitrogen tank, put it indoors safely and should not fall over, dry naturally, or air dry with a blower as described above. Note that during the entire brushing process, the action should be slow, the temperature of the inverted water should not exceed 40 °C, and the total weight should not exceed 2 kg.
