Small liquid nitrogen machine operation tips

Compared with the gas supply of the steel cylinder, the gas supply of the small 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 Yunnan liquid nitrogen dewars. The editor here introduces the precautions in the use of the small liquid nitrogen machine , so that users who have just come into contact with it can understand and master it. The gas contained in the small 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 of the small liquid nitrogen machine is too high in the tank, it will release the gas to the outside. Therefore, keep the storage place ventilated to avoid suffocation caused by high gas concentration. The Dewar should be placed upright 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, when the valves and pipes are frozen, they must be disassembled after being drenched with water, and must not be disassembled violently.
