Cholekanitsa Magnetic cha CGC Cryogenic Superconducting
Kugwiritsa ntchito
Zogulitsazi zili ndi mphamvu ya maginito yapamwamba kwambiri yomwe siingapezeke ndi zida wamba zamagetsi, ndipo zimatha kulekanitsa bwino zinthu zamaginito zomwe zimakhala zochepa mu mchere wosalala. Ndizoyenera kupangira zitsulo zosowa, zitsulo zopanda chitsulo ndi zitsulo zopanda chitsulo, monga kuwonjezera mchere wa cobalt, kuchotsa zodetsa ndi kuyeretsa miyala ya kaolin ndi feldspar yopanda chitsulo, ndipo zingagwiritsidwenso ntchito poyeretsa zimbudzi ndi kuyeretsa madzi a m'nyanja ndi madera ena.
Mfundo Yogwirira Ntchito
Cholekanitsa maginito cha superconducting chimagwiritsa ntchito khalidwe lakuti kukana kwa superconducting coil ndi zero pa kutentha kochepa, Gwiritsani ntchito mphamvu yayikulu kuti mudutse mu superconducting coil yomwe imamizidwa mu helium yamadzimadzi, ndikusangalatsidwa ndi mphamvu yakunja ya DC, kotero kuti superconducting magnetic separator ikhoza kufika mphamvu ya maginito yakumbuyo yoposa 5T, pamwamba pa Matrix yachitsulo chosapanga dzimbiri choyendetsa maginito m'chipinda cholekanitsa imapanga mphamvu yayikulu yamaginito, yomwe imatha kufika pa 10T, yomwe imatha kulekanitsa bwino zinthu zamaginito ndipo ndiyo njira yabwino kwambiri mu gawo lopatsa mphamvu maginito.
Njira yosankhiramo imakhala ndi masilinda atatu enieni ndi masilinda awiri osankhiramo. Silinda yosankhiramo ndi silinda yeniyeni zimatha kupeza mphamvu ya maginito, kotero kuti njira yosankhiramo imatha kuyenda mu mphamvu ya maginito mothandizidwa ndi mphamvu yaying'ono yakunja.
Njira yosankhidwira imayendetsedwa ndi injini ndi makina oyendetsera lamba kuti zigwirizane mkati mwa nthawi yoikika. Njira yogawanitsira ndi yakuti silinda imodzi yogawanitsira imasankhiratu zamkati mwa maginito ndi mphamvu ya kumbuyo pamwamba pa 5T, ndipo silinda ina yogawanitsira imatsukidwa kunja kwa maginito. Popeza palibe mphamvu ya maginito, tinthu ta m'nthaka sitikhudzidwa ndi mphamvu ya maginito, ndipo ubweya wachitsulo umatsukidwa ndi madzi amphamvu, zinthu zamaginito zomwe zimamatiridwa zimatulutsidwa ndi madzi, silinda yogawanitsira yomwe ikugwira ntchito mu maginito imachotsedwa mu maginito, ndipo silinda yogawanitsira yoyeretsedwa imabwerera ku maginito kuti isanjidwe zamkati, ndipo kuzungulirako kumabwerezedwa, nthawi zonse pamakhala silinda yogawanitsira mu maginito kuti isanjidwe zamkati, zomwe zimapangitsa kuti ntchito yopanga ikhale yabwino kwambiri.
Zinthu Zaukadaulo
- Mphamvu ya maginito yakumbuyo, coil yopangidwa ndi zinthu zoyendetsera mphamvu ya Nb-Ti ili ndi mphamvu ya maginito yoposa 5T, pomwe mphamvu ya maginito yachizolowezi nthawi zambiri imakhala yochepera 2T, zomwe ndi nthawi 2-5 kuposa chinthu chachikhalidwe.
- Mphamvu yamphamvu ya maginito, pansi pa mphamvu ya kumbuyo kwa munda pamwamba pa 5T, pamwamba pa matrix yolowera m'chipinda cholekanitsa imapanga mphamvu yayikulu kwambiri ya maginito, yomwe imatha kulekanitsa bwino zonyansa zofooka za maginito, kukonza kwambiri ubwino wa mchere wosakhala wachitsulo, ndikukwaniritsa zofunikira za zinthu zapamwamba.
- Ngati helium yamadzimadzi siikusinthasintha, firiji ya 1.5W/4.2K ikhoza kupitiliza kuzizira, kotero kuti helium yamadzimadzi isawonongeke kunja kwa maginito, kuonetsetsa kuti kuchuluka kwa helium yamadzimadzi sikunasinthe, ndipo palibe chifukwa chobwezeretsanso helium yamadzimadzi mkati mwa zaka zitatu, zomwe zimachepetsa ndalama zokonzera.
- Kugwiritsa ntchito mphamvu zochepa, pogwiritsa ntchito ukadaulo wa superconducting wotsika kutentha, kukana kwa coil kumakhala zero ikafika pa superconducting state. Firiji yomwe imangofunika kusunga kutentha kochepa kwa maginito imagwira ntchito, zomwe zimasunga magetsi opitilira 90% poyerekeza ndi maginito wamba operekera mphamvu.
- Nthawi yochepa yoyambitsa chisangalalo. Ndi yochepera ola limodzi.
- Masilinda awiriwa amasankhidwa mosiyanasiyana ndikutsukidwa, ndipo amatha kugwira ntchito mosalekeza popanda demagnetization, zomwe zimapangitsa kuti ntchito iyende bwino. Cholekanitsa maginito cha 5.5T/300 chowongolera maginito chimatha kukonza kaolin mpaka matani 100 patsiku la miyala youma, ndipo cholekanitsa maginito cha 5T/500 chowongolera maginito chimatha kukonza matani 300 patsiku la kaolin.
- Njira yonseyi imayang'aniridwa ndi kompyuta yaying'ono, ndipo magawo amatha kusonkhanitsidwa nthawi yeniyeni, zomwe zimathandiza kuwongolera kupanga ndi kuwongolera khalidwe.
- Zipangizozi zimagwira ntchito bwino, mtengo wokonza ndi wotsika kwambiri, maginito amakhala nthawi yayitali, kulemera kwake ndi kosavuta kukhazikitsa.
