Subaxdii Jannaayo 13, 2021, heer kulka sare ee adduunka ugu horreeya ee sameeya tusaalaha injineernimada xawaaraha sare ee maglev iyo khadka tijaabada iyadoo la adeegsanayo tignoolajiyada asalka ah ee Jaamacadda Southwest Jiaotong ayaa si rasmi ah looga bilaabay Chengdu, Gobolka Sichuan, Shiinaha.Waxay calaamad u tahay horumarka xoqitaanka ee cilmi-baarista heerkulka sare ee mashruuca maglev xawaaraha sare ee Shiinaha iyo waddankeena ayaa leh shuruudaha tijaabada injineernimada iyo bandhigyada.
Kiiskii Kowaad ee Adduunka;Abuur Horudhac
Hawlgelinta khadka tijaabada tignoolajiyada levitation-ka heer-kulka sare-sare waa kan ugu horreeya adduunka.Waa wakiil ka mid ah wax soo saarka Shiinaha ee caqli-gal ah oo abuuray horudhac ah oo ku saabsan berrinka heerkulka sare ee heerkulbeegga.
Heerkulka sare ee tiknoolajiyada tareenka ee maglev ayaa leh faa'iidooyinka xasillooni la'aan, qaabdhismeed fudud, badbaadinta tamarta, ma jirto kiimiko iyo wasakhowga buuqa, badbaadada iyo raaxada, iyo kharashka hawlgalka oo hooseeya. Waa nooc cusub oo tareen oo cusub, oo ku habboon noocyada xawaaraha kala duwan, gaar ahaan ku habboon hawlgalka xariiqyada xawaaraha sare iyo ultra-sare;Farsamadani waa tignoolajiyada tareenka maglev heerkul sare si fiican u maamula oo leh astaamo is-hakin, is-hagaaya, iyo astaamo is dejineed.Waa habka cusub ee gaadiidka tareenada caadiga ah oo wajahaya horumarinta mustaqbalka iyo rajada codsiga ballaaran. Farsamada ayaa marka hore lagu farsameeyaa jawiga jawiga, iyo qiimaha la filayo xawaaraha hawlgalka ayaa ka weyn 600 km / h, kaas oo la filayo inuu abuuro cusub. diiwaanka xawaaraha socodka dhulka ee jawiga jawiga.
Talaabada xigta waa in la isku daro tignoolajiyada mustaqbalka ee dhuumaha faakuumka si loo horumariyo hannaan gaadiid oo dhammaystiran oo buuxinaya daldaloolada gaadiidka dhulka iyo xawaaraha gaadiidka hawada, kaas oo seeska u dhigi doona horumar muddo dheer ah oo lagu gaadho xawaare ka sarreeya 1000 km/h, si loo dhiso qaabka cusub ee gaadiidka dhulka.Horu-u-eegidda iyo isbeddellada carqaladaynta ku ah horumarinta gaadiidka tareenka.

Tignoolajiyada Magnetic Lewitation
Waqtigan xaadirka ah, waxaa jira saddex tignoolajiyada "super magnetic levitation" adduunka.
Tignoolajiyada levitation Electromagnetic ee Jarmalka:
Mabda'a elektromagnetic-ka waxaa loo isticmaalaa in lagu xaqiijiyo socodka ka dhexeeya tareenka iyo jidka.Waqtigan xaadirka ah, tareenka Maglev Shanghai, tareenka maglev ee laga dhisayo Changsha iyo Beijing ayaa dhamaantood ku jira tareenkan.
Farsamada levitation-ka birlabeedka heerkulka hooseeya ee Japan:
Isticmaal sifooyinka sare ee walxaha qaarkood heerkul hooseeya (la qaboojiyey ilaa -269°C oo leh helium dareere ah) si tareenku u kiciyo, sida khadka Shinkansen maglev ee Japan.
Tignoolajiyada magnetic levitation-ka heerkulka sare ee Shiinaha:
Mabda'a asal ahaan wuxuu la mid yahay kan heerkulka hooseeya ee kor u kaca, laakiin heerkulka shaqadu waa -196 ° C.
Tijaabooyinkii hore, magnetic levitation ee waddankeena kaliya ma aha in la hakiyo laakiin sidoo kale la hakiyo.

Faa'iidooyinka Heerkulka Sare ee Tareenka Maglev
Badbaadinta tamarta:Levitation iyo hagitaan uma baahna kontorool firfircoon ama sahay koronto baabuur, nidaamkuna waa mid fudud.Joojinta iyo hagitaanku waxay u baahan yihiin kaliya in lagu qaboojiyo nitrogen dareere ah oo raqiis ah (77 K), iyo 78% hawadu waa nitrogen.
Ilaalinta deegaanka:Heerkulka sare ee kondhomka sare ee magnetka wuxuu noqon karaa levitation statically, gebi ahaanba aan buuq lahayn;Jidka birlabeedka joogtada ahi waxa uu abuuraa goob birlab ah (magnetic field), goobta magnetic meesha ay rakaabku taabtaana waa eber, mana jirto wasakh koronto.
Xawaare sare:Dhererka levitation-ka (10-30 mm) waxaa loo qaabayn karaa sidii loo baahnaa, waxaana loo isticmaali karaa in lagu socodsiiyo joog ilaa hoose, dhexdhexaad, xawaarihiisa sare iyo xawaarihiisa ultra-sare.Marka la barbar dhigo tignoolajiyada kale ee levitation magnetic, waxay aad ugu habboon tahay gaadiidka dhuumaha vacuum (in ka badan 1000 km/h).
Badbaadada:Xoogga levitation wuxuu si xad dhaaf ah u kordhaa hoos u dhaca dhererka levitation-ka, iyo badbaadada hawlgalka waa la sugi karaa iyada oo aan la xakameynin jihada toosan.Nidaamka hagitaan is-dejinta ayaa sidoo kale xaqiijin kara hawlgalka badbaadada leh ee jihada toosan.
Raaxada:"Awoodda pinning" ee gaarka ah ee heerkulka sare ee heerkulka sare ayaa ilaaliya jidhka baabuurka kor iyo hoosba, taas oo ah xasillooni ay adag tahay in baabuur kastaa gaaro.Waxa rakaabku la kulmaan marka ay fuulayaan waa "dareenka dareen la'aan".
Kharash hawlgal oo hooseeya:Marka la barbar dhigo jarmalka joogtada ah ee dhaqdhaqaaqa magnetic levitation baabuurta iyo Japan heerkulka hoose ee superconducting baabuurta levitation magnetic isticmaalaya helium dareere ah, waxa ay leedahay faa'iidooyinka miisaanka fudud, qaab-dhismeedka fudud, iyo hooseeyo wax soo saarka iyo kharashka hawlgalka.
Codsiga Sayniska iyo Farsamada ee dareeraha Nitrogen
Sababo la xiriira sifooyinka kontaroolada sare, koontaroolaha sare wuxuu u baahan yahay in lagu geliyo jawi nitrogen dareere ah -196 ℃ inta lagu jiro shaqada.
Heerkulka sare ee kondhomka magnetic levitation waa tignoolajiyada adeegsata astaamaha qulqulka magnetic ee agabka badan ee heerkulka sareeyo si loo gaadho levitation deggan iyada oo aan la xakamayn firfircoonayn.
Baabuurka Buuxinta Nitrojiinka Dareeraha ah
Baabuurta buuxinta nitrogen dareeraha ah waa badeecad ay samaysay oo ay samaysay Sichuan Haishengjie Cryogenic Technology Co., Ltd. ee loogu talagalay mashruuca heer-kulka sare ee xawaaraha sare ee maglev. Waa udub dhexaadka tignoolajiyada maglev-Dewar kabka nitrogen dareeraha ah.
△ Codsiga Goobta ee Baabuurka Buuxinta Nitrogen-ka dareeraha ah △
Naqshadaynta moobiilka, shaqada buuxinta nitrogen dareeraha ah ayaa si toos ah looga ogaan karaa tareenka agtiisa.
Nidaamka buuxinta nitrogen dareeraha nus-otomaatigga ah wuxuu ku siin karaa 6 dewars leh nitrogen dareere isku mar ah.
Nidaamka xakamaynta madax-bannaan ee lix-geesoodka ah, deked kasta oo dib-u-buuxin ah ayaa loo xakameyn karaa si gaar ah.
Ilaalinta cadaadiska hooseeya, ka ilaali gudaha Dewar inta lagu jiro habka buuxinta.
24V ilaalinta danab badbaadada.
Haanta sahayda ee is-cadaadisay
Waa haan sahayda oo iskeed isu cadaadisay oo si gaar ah loo sameeyay loona sameeyay kaydka nitrogen dareeraha ah.Had iyo jeer waxay ku saleysan tahay qaab dhismeedka nabdoonaanta leh, tayada wax soo saarka ee wanaagsan iyo maalmo kaydinta dheer ee nitrogen dareeraha ah.

Mashruuca oo socda
Dhowr maalmood ka hor, waxaan la shaqeynay khabiiro ka socda Jaamacadda Southwest Jiaotong
Qabtay shaqada cilmi baadhiseed ee dabagalka ah ee mashruuca maglev-xawaaraha sare ee heerkulka sare
Goobta Seminar-ka △
Aad ayaa loo sharfay inaan awoodno inaan ka qaybqaadanno shaqadan hormuudka ah markan.Mustaqbalka, waxaan sidoo kale sii wadi doonaa inaan la kaashanno dabagalka shaqada cilmi baarista ee mashruuca si aan u samayno tallaabo kasta oo suurtagal ah oo lagu hormarinayo shaqadan hormuudka ah.
Waxaan aaminsanahay
Sayniska iyo tignoolajiyada Shiinaha waa hubaal inay guulaysan doonaan
Mustaqbalka Shiinaha waxaa ka buuxa rajooyin
