Operation tips of liquid nitrogen machine

As a refrigeration equipment, we should pay attention to the correctness of our use method

Compared with the gas supply of the cylinder, the gas supply of the Dewar liquid nitrogen machine has the advantages of large storage capacity, high gas purity, convenient transportation, high performance and economical benefits. Therefore, it is very common for customers to use liquid nitrogen machines now. The editor will introduce the precautions in the use of the liquid nitrogen machine here, so that users who have just come into contact with it can understand and master it. The gas contained in the liquid nitrogen machine (liquid nitrogen, liquid oxygen, liquid chlorine or liquid carbon dioxide). The low temperature can be minus 196 degrees, so it is necessary to avoid direct skin contact with liquid gas during use to prevent frostbite. When the gas in the Dewar tank is too high in pressure, it will release the gas to the outside. Therefore, keep the storage place ventilated to avoid suffocation caused by high gas concentration. The liquid nitrogen machine should be placed vertically during use and transportation to avoid tilting. Prevents liquid from draining from the .. valve, causing frostbite and damage to the dewar. During use, the force when opening and closing the valve should not be too large. Due to the large amount of gas used, the valves and pipes are frozen, and they must be disassembled after being drenched with water, and must not be disassembled violently.
