Itekhnoloji ye-Magnetic Levitation
Okwangoku, kukho iitekhnoloji ezintathu ze "super magnetic levitation" kwihlabathi.
Itekhnoloji ye-electromagnetic levitation eJamani:
Umgaqo we-electromagnetic usetyenziselwa ukuqonda i-levitation phakathi kukaloliwe kunye nomzila.Ngoku, uloliwe wemaglev waseShanghai, uloliwe wemaglev osakhiwa eChangsha naseBeijing zonke zikulo loliwe.
Itekhnoloji yaseJapan yobushushu obuphantsi be-superconducting magnetic levitation:
Sebenzisa iipropathi ze-superconducting zezixhobo ezithile kumaqondo aphantsi (apholile ukuya kwi -269 ° C kunye ne-helium engamanzi) ukwenza isitimela sibe nevitate, njengomgca we-Shinkansen maglev eJapan.
Itekhnoloji yaseTshayina yobushushu obuphezulu be-superconducting magnetic levitation:
Umgaqo ngokusisiseko uyafana naleyo ye-superconductivity yobushushu obuphantsi, kodwa ubushushu bayo bokusebenza buyi-196°C.
Kuvavanyo lwangaphambili, oku kutsalwa kwemagnethi kwilizwe lethu akunakunqunyanyiswa kuphela kodwa kunqunyanyiswe.

Izinto eziluncedo kwi-High Temperature Superconducting Maglev Train
Ugcino lwamandla:I-Levitation kunye nesikhokelo ayifuni ulawulo olusebenzayo okanye unikezelo lwamandla esithuthi, kwaye inkqubo ilula.Ukunqunyanyiswa kunye nesikhokelo kufuneka kupholiswe kuphela ngenitrogen engamanzi exabiso eliphantsi (77 K), kunye nama-78% omoya yinitrogen.
Ukhuseleko lokusingqongileyo:I-high-temperature superconducting levitation magnetic ingaba yi-levitation statically, ngokupheleleyo ngaphandle kwengxolo;Umzila wemagnethi osisigxina uvelisa indawo yemagnethi emileyo, kunye nemagnethi kwindawo apho abakhweli bachukumisa inguziro, kwaye akukho lungcoliseko lwe-electromagnetic.
Isantya esiphezulu:Umphakamo welevitation (10 ~ 30 mm) unokuyilwa njengoko kufuneka, kwaye ingasetyenziselwa ukugijima ukusuka kwi-static ukuya kwi-low, medium, high speed kunye ne-ultra-high speed.Xa kuthelekiswa nobunye ubuchwephesha bemagnetic levitation, ifaneleke ngakumbi kuthutho lwemibhobho yofutha (ngaphezu kwe-1000 km/h).
Ukhuseleko:I-levitation force iyanda ngokukhawuleza ngokuncipha kokuphakama kwe-levitation, kwaye ukhuseleko lokusebenza lunokuqinisekiswa ngaphandle kokulawula kwicala elithe nkqo.Inkqubo yesikhokelo yokuzinzisa inokuqinisekisa ukusebenza ngokukhuselekileyo kwicala elithe tye.
Ukuthuthuzela:I-"pinning force" ekhethekileyo ye-high-temperature superconductor igcina umzimba wemoto uzinzile kwaye uphantsi, obunzima obunzima ukuba nayiphi na isithuthi siphumelele.Into abayifumanayo abakhweli xa bekhwele "yimvakalelo yokungabi namvakalelo".
Iindleko zokusebenza eziphantsi:Xa kuthelekiswa ne-German constant-conductivity magnetic levitation vehicles kunye ne-Japan low-temperature superconducting levitation vehicles usebenzisa i-helium engamanzi, ineenzuzo zobunzima bokukhanya, ulwakhiwo olulula, kunye neendleko eziphantsi zokwenziwa kunye nokusebenza.
Ukusetyenziswa kweNzululwazi kunye neTekhnoloji yeNitrogen yolwelo
Ngenxa yeempawu ze-superconductors, i-superconductor kufuneka ifakwe kwindawo ye-nitrogen engamanzi kwi--196 ℃ ngexesha lomsebenzi.
Ubushushu obuphezulu be-superconducting magnetic levitation yitekhnoloji esebenzisa iimpawu ze-magnetic pinning ze-high-temperature superconducting bulk materials ukuze kuphunyezwe i-levitation ezinzileyo ngaphandle kolawulo olusebenzayo.
Ilori yokuZalisa iNitrojeni engamanzi
Iloli yokuzalisa i-nitrogen ye-liquid yimveliso eyenzelwe kwaye yaphuhliswa nguSichuan Haishengjie Cryogenic Technology Co., Ltd. kwiprojekthi ye-high-speed maglev yeprojekthi ye-high-speed maglev.Ingundoqo yeteknoloji ye-maglev-iDewar yongezelela i-nitrogen engamanzi.
△ Ukusetyenziswa kweNdawo yeLori yokuZalisa iNitrojeni engamanzi △
Uyilo oluselfowuni, umsebenzi wokuzalisa initrogen elulwelo unokufumaneka ngokuthe ngqo ecaleni kukaloliwe.
Inkqubo yokuzaliswa kwe-nitrogen ye-semi-automatic liquid inokubonelela nge-6 dewars kunye ne-nitrogen engamanzi ngexesha elinye.
Indlela emithandathu yolawulo oluzimeleyo, izibuko lokuzalisa ngokutsha ngalinye linokulawulwa ngabanye.
Ukukhuselwa koxinzelelo oluphantsi, khusela ngaphakathi kweDewar ngexesha lokuzaliswa kwakhona.
24V ukhuseleko lombane wokhuseleko.
ITanki yokuNika ngokuZicinezelayo
It is a self-pressurized unikezelo itanki ephuhliswe ngokukodwa kwaye yenzelwe ulwelo nitrogen reserve.Ihlala isekelwe kwisakhiwo soyilo esikhuselekileyo, umgangatho obalaseleyo wokuvelisa kunye neentsuku zokugcinwa kwexesha elide le-nitrogen engamanzi.
