Kwihlabathi le-cryogenics, imfuneko yokukhusela ubushushu ngendlela esebenzayo nethembekileyo ibaluleke kakhulu, ingakumbi xa kufikwa ekuthuthweni kwezinto ezipholileyo njenge-helium engamanzi.Imibhobho enejekethi yokucoca umoya(VJP) bubuchwepheshe obuphambili ekunciphiseni ukudluliselwa kobushushu nokuqinisekisa ukuba ulwelo olukhanyayo olufana ne-helium yolwelo luhlala kumaqondo obushushu aphantsi afunekayo ngexesha lokuthuthwa. Eli nqaku liphonononga indima ebalulekileyo yemibhobho enejakethi ye-vacuum kwizicelo ze-helium yolwelo.

Zithini ii-Vacuum Jacketed Pipes?

Imibhobho enejekethi yokucoca umoya, ezaziwa ngokuba ziipayipi ezigqunyiweyo, ziipayipi ezikhethekileyo ezinomaleko wokugquma we-vacuum phakathi kweendonga ezimbini zepayipi ezixineneyo. Olu maleko wokugquma lusebenza njengomqobo wobushushu osebenza kakuhle kakhulu, luthintela ukudluliselwa kobushushu ukuya okanye ukusuka kwizinto ezikuyo. Kwi-helium engamanzi, ebila kubushushu obumalunga ne-4.2 Kelvin (-268.95°C), ukugcina amaqondo obushushu aphantsi kangako ngexesha lokuhamba kubalulekile ukuze kuthintelwe ukufuma kunye nokulahleka kwezinto.

Ukubaluleka kweeMbhobho zeVacuum Jacketed kwiiNkqubo zeHelium eziLulwelo

I-helium engamanzi isetyenziswa kakhulu kumashishini afana nokhathalelo lwempilo (kwiimashini ze-MRI), uphando lwesayensi (kwii-particle accelerators), kunye nokuhlola isithuba (ukupholisa izinto zeenqwelo-moya). Ukuthutha i-helium engamanzi kumgama ngaphandle kokunyuka okukhulu kobushushu kubalulekile ekunciphiseni inkunkuma nokuqinisekisa ukusebenza kakuhle kwenkqubo.Imibhobho enejekethi yokucoca umoyazenzelwe ukugcina ulwelo kubushushu obufunekayo ngokunciphisa kakhulu ukutshintshiselana kobushushu.

Ukuncipha koKufumana uBushushu kunye noKulahlekelwa nguMphunga

Enye yezona nzuzo ziphambili zeimibhobho enejakethi yokucoca ulwelokwiinkqubo ze-helium ezingamanzi ziyakwazi ukuthintela ukungena kobushushu. Umaleko we-vacuum ubonelela ngomqobo ofanelekileyo kwimithombo yobushushu yangaphandle, nto leyo enciphisa kakhulu amazinga okubila. Oku kubalulekile ekugcineni imeko yolwelo ye-helium ngexesha lokuthuthwa kwimigama emide. Ngaphandle kokusetyenziswa kwe-vacuum insulation, i-helium iya kutshabalala ngokukhawuleza, nto leyo ekhokelela ekulahlekelweni kwemali kunye nokungasebenzi kakuhle kokusebenza.

Ukuqina kunye nokuguquguquka

Imibhobho enejekethi yokucoca umoyaEzi zisetyenziswa kwiinkqubo ze-helium ezingamanzi zenzelwe ukuqina, zihlala zakhiwe ngentsimbi engagqwaliyo okanye ezinye izinto ezinokumelana namaqondo obushushu aphezulu kunye noxinzelelo loomatshini. Ezi mbhobho zikwaza noyilo oluguquguqukayo, okuvumela ukufakwa lula kwiinkqubo ezinokufuna iindlela ezigobileyo okanye eziguquguqukayo. Olu kuguquguquka kuzenza zilungele iziseko ezintsonkothileyo ezifana neelabhoratri, iitanki zokugcina izinto ezikrwada, kunye neenethiwekhi zothutho.

Isiphelo

Imibhobho enejekethi yokucoca umoyazidlala indima ebalulekileyo ekuthuthweni kwe-helium engamanzi, zibonelela nge-insulation yobushushu esebenza kakuhle kakhulu enciphisa ukwanda kobushushu kwaye inciphise ilahleko. Ngokugcina ukuthembeka kolwelo oluyi-cryogenic, le mibhobho inceda ukugcina i-helium exabisekileyo kunye nokunciphisa iindleko zokusebenza. Njengoko amashishini eqhubeka nokuvelisa izinto ezintsha kwaye efuna iinkqubo eziphucukileyo ze-cryogenic, indimaimibhobho enejakethi yokucoca ulweloziya kukhula ngokubaluleka. Ngenxa yokusebenza kwazo okungefaniyo nobushushu kunye nokuqina kwazo,imibhobho enejakethi yokucoca ulweloihlala ilubuchwepheshe obuphambili kwicandelo le-cryogenics, ngakumbi ekusetyenzisweni kwe-helium engamanzi.

Ukuququmbela,imibhobho enejakethi yokucoca ulwelo(VJP) zibaluleke kakhulu ekusetyenzisweni kwe-helium engamanzi, zenza kube lula ukuthuthwa ngokufanelekileyo, ukunciphisa inkunkuma, kunye nokuqinisekisa ukhuseleko kunye nokuthembeka kweenkqubo ze-cryogenic.
