Umsebenzi wenxalenye nganye ye-cryogenic Dewar

I-Dewar ikwabizwa ngokuba yi-thermos, isikhongozeli esifanelekileyo kunye nesixhobo sokugcina igesi engamanzi, uphando lobushushu obuphantsi kunye nokhuseleko lwekristale. I-Dewar yanamhlanje yaqanjwa yingcali yefiziksi yaseScotland kunye nekhemisti uSir James Dewar.

Ulwakhiwo oluphambili lweDewar kunye nomsebenzi wecandelo ngalinye lulandelayo:
1. I-cylinder yangaphandle: Ngaphandle kokukhusela umzimba wangaphandle we-barrel yangaphakathi, iphinda ifake i-vacuum interlayer kunye ne-barrel yangaphakathi ukukhusela ukungena kobushushu ngaphandle kwebhotile kunye nokunciphisa i-vaporization yendalo ye-cryogenic liquid kwibhotile;
2. I-cylinder yangaphakathi: gcina ulwelo lwe-cryogenic;
3. I-Vaporizer: Ngokutshintshana kobushushu kunye nodonga lwangaphakathi lombhobho wangaphandle, igesi engamanzi kwibhotile inokuguqulwa ibe yimeko yegesi;

4. Ivalve yolwelo: lawula ibhotile yeDewar ukuzalisa okanye ukukhupha ulwelo kwibhotile;
5. Ivalve yokhuseleko: Xa uxinzelelo lwesitya sikhulu kunoxinzelelo oluphezulu lokusebenza, uxinzelelo luyakhululeka ngokuzenzekelayo, kwaye uxinzelelo lokukhupha lukhulu kancinane kunoxinzelelo oluphezulu lokusebenza;
6. I-valve yokukhupha: Xa ibhotile ye-Dewar igcwele i-liquid, sebenzisa le valve ukukhupha igesi kwindawo yesigaba segesi kwibhotile ukunciphisa uxinzelelo kwibhotile yokuzalisa ulwelo ngokukhawuleza nangokufanelekileyo. Omnye umsebenzi kukuba xa uxinzelelo kwibhotile ye-Dewar ludlula uxinzelelo oluphezulu lokusebenza ngexesha lokugcinwa okanye ezinye iimeko, i-valve ingasetyenziselwa ukukhupha ngesandla igesi kwibhotile ukunciphisa uxinzelelo kwibhotile;

7. I-Pressure gauge: ibonisa uxinzelelo lwe-cylinder yangaphakathi yebhotile;
8. Ivalve ye-Booster: Emva kokuba le valve ivuliwe, ulwelo olusebhotileni luya kutshintshisa ubushushu kunye nodonga lwangaphandle lwe-cylinder nge-coil ye-booster, i-vaporize ibe yigesi, ingene kwisithuba sesigaba segesi ngaphezu kodonga lwangaphakathi lwe-cylinder, kwaye imise i-drive ethile ye-cylinder yegesi Uxinzelelo (uxinzelelo lwangaphakathi) ukwenzela ukuba uqhube ubushushu obuphantsi buye buqhube ulwelo kwibhotile;
9. Ivalve yokusebenzisa: Isetyenziselwa ukuvula indlela yombhobho yesekethe yolwelo lweDewar kunye nesiphelo sokungenisa igesi somsebenzisi, kwaye le valve ingasetyenziselwa ukulawula izinga lokuhamba kwerhasi;
10. I-gauge yenqanaba lolwelo: bonisa ngokucacileyo inqanaba lenqanaba le-liquid kwisitya, indawo yokufakela kufuneka ibe lula ukuba umqhubi aqaphele kwaye alungise.
