Kryogen kylskåp

1. Device for liquefying air, oxygen and nitrogen: The single-stage Stirling refrigerator can produce a low temperature of 77K, which can be used to directly liquefy air, oxygen and nitrogen under normal pressure. This machine is equipped with a purifying cooling condenser and a thermal insulation layer on the outside of the cold head of the refrigerator for purifying and liquefying the gas. When the machine works normally, the temperature of the cold head drops to 77K, which creates a certain℃of vacuum in the outer space of the condenser. At this time, the cork on the top is pulled out, and the air (when connected to the oxygen and nitrogen bottles, it is oxygen, Nitrogen) is inhaled, gradually cooled and purified in the direction of Pilen i figuren och flytande sedan genom utsidan av kondensorn . Slutligen flyter den flytande gasen ut genom utloppsröret i pilens riktning .

2. Device for liquefying bag, neon and helium: two-stage St, GM and SV refrigerators can be used to directly liquefy hydrogen, neon and other gases under normal pressure. Generally, the devices used in this kind of occasions are mostly St machines, and GM or SV refrigerators are used when the vibration is required to be extremely small and the cold day is liten .

3. Cryogenic Pump Device: Den kryogena pumpanordningen är en anordning som använder principerna för låg temperaturkondensation, kall fångst och låg temperaturadsorption för att extrahera gas för att få en ren och föroreningsfri högvakuum .
