Mangwanani aNdira 13, 2021, yekutanga pasirese tembiricha yepamusoro-soro inomhanyisa maglev engineering prototype uye mutsetse wekuyedza uchishandisa tekinoroji yekutanga yeSouthwest Jiaotong University yakatangwa zviri pamutemo muChengdu, Sichuan Province, China.Inotaridza budiriro kubva mukutanga mukutsvagisa tembiricha yepamusoro superconducting yakakwira yekumhanya maglev chirongwa muChina uye nyika yedu ine mamiriro einjiniya kuyedza uye kuratidzira.
Nyaya Yekutanga Munyika; Gadzira Muenzaniso
Iko kumisikidzwa kweyepamusoro-tembiricha superconducting magineti levitation tekinoroji test line ndiyo yekutanga munyika.Iyo inomiririra yekugadzira yakangwara yeChina uye yakagadzira muenzaniso mumunda wepamusoro-tembiricha superconductivity.
Iyo yepamusoro-tembiricha superconducting maglev chitima tekinoroji ine zvakanakira zvekusina kugadzikana sosi, chimiro chakareruka, kuchengetedza simba, hapana chemikemikari uye ruzha kusvibiswa, kuchengeteka uye kunyaradza, uye yakaderera yekushandisa mutengo.Iyo yakanaka mhando yekufambisa njanji, yakakodzera zvakasiyana-siyana zvekumhanya domains, kunyanya zvakakodzera kushanda kwepamusoro-kumhanya uye ultra-high-speed mitsara;Iyi tekinoroji ndeyepamusoro-tembiricha superconducting maglev chitima tekinoroji ine kuzvimisa, kuzvitungamira, uye kuzvisimbisa.Iyi inzira itsva yakajairika yekufambisa njanji yakatarisana nebudiriro yeramangwana uye tarisiro yakafara yekushandisa. Tekinoroji inotanga kugadzirwa munzvimbo yemhepo, uye inotarisirwa kukurumidza kukurumidza yekufambisa kukosha inodarika 600 km/h, inotarisirwa kugadzira itsva. rekodhi yekumhanyisa traffic pasi munzvimbo yemhepo.
Danho rinotevera nderekubatanidza tekinoroji yeramangwana yevacuum pombi yekugadzira hurongwa hwakazara hwekufambisa hunozadza mikaha mukufambisa kwepasi uye kumhanya kwekufambisa kwemhepo, inozoisa hwaro hwebudiriro yenguva refu mukumhanya pamusoro pe1000 km/h, nekudaro kuvaka mhando itsva yekufambisa kwenyika.Shanduko dzinotarisa kumberi uye dzinokanganisa mukugadzirwa kwenjanji.

Magnetic Levitation Technology
Parizvino, kune matatu "super magnetic levitation" matekinoroji munyika.
Electromagnetic levitation tekinoroji muGermany:
Iyo electromagnetic musimboti inoshandiswa kuona kuyerera pakati pechitima nenjanji.Parizvino, chitima cheShanghai maglev, chitima che maglev chiri kuvakwa muChangsha neBeijing zvose zviri muchitima ichi.
YeJapan yakaderera-tembiricha superconducting magineti levitation tekinoroji:
Shandisai superconducting properties yezvimwe zvinhu patembiricha yakadzikira (yakatonhodzwa kusvika -269°C ine liquid helium) kuita kuti chitima chibude, seShinkansen maglev line kuJapan.
China yepamusoro-tembiricha superconducting magineti levitation tekinoroji:
Nheyo yacho yakangofanana neyeyepasi-tembiricha superconductivity, asi tembiricha yayo yekushanda i -196 ° C.
Mukuedza kwekare, iyi magnetic levitation munyika yedu haigoni kumiswa chete asiwo kumiswa.

Zvakanakira Kupisa Kwepamusoro Superconducting Maglev Chitima
Kuchengetedza magetsi:Revhiti uye kutungamira hazvitsvage kutonga kunoshanda kana magetsi emotokari, uye system yacho iri nyore.Kuturika uye kutungamira kunongoda chete kutonhodzwa nemvura yakachipa yenitrogen (77 K), uye 78% yemhepo initrogen.
Kuchengetedza kwezvakatipoteredza:Iyo yepamusoro-tembiricha superconducting magineti levitation inogona kuve yakagadziriswa statically, zvachose pasina ruzha;iyo yekusingaperi magineti track inogadzira inomira magineti, uye iyo magineti munzvimbo inobatwa nevafambi i zero, uye hapana kusvibiswa kwemagetsi.
Kumhanya kwepamusoro:Iyo levitation kureba (10 ~ 30 mm) inogona kugadzirwa sezvinodiwa, uye inogona kushandiswa kumhanya kubva pastatic kusvika yakaderera, yepakati, yakakwirira kumhanya uye yekupedzisira-yakanyanya kumhanya.Kana ichienzaniswa nemamwe magineti levitation tekinoroji, inonyanya kukodzera kutakura pombi yevacuum (kupfuura 1000 km/h).
Safety:Simba rekuita rinowedzera zvakanyanya nekudzikira kwekureba, uye kuchengetedza kwekushanda kunogona kuvimbiswa pasina kutonga munzira yakatwasuka.Iyo yekuzvisimbisa yekutungamira sisitimu inogona zvakare kuve nechokwadi chekushanda kwakachengeteka munzira yakachinjika.
Nyaradzo:Iyo yakakosha "pinning simba" ye-high-temperature superconductor inoita kuti muviri wemotokari ugadzikane kumusoro uye pasi, iko kugadzikana kwakaoma kune chero mota kuti iwane.Zvinosangana nevafambi kana vakatasva "kunzwa kusanzwa".
Mari yekushandisa yakaderera:Kuenzaniswa neGerman inogara-conductivity magineti levitation mota uye yeJapan yakaderera-tembiricha superconducting magineti levitation mota dzinoshandisa mvura helium, ine zvakanakira uremu huremu, chimiro chakareruka, uye yakaderera yekugadzira uye mutengo wekushandisa.
Sainzi uye Tekinoroji Kushandiswa kweLiquid Nitrogen
Nekuda kwehunhu hwe superconductors, iyo superconductor inoda kunyudzwa mumvura ine nitrogen nharaunda pa -196 ℃ panguva yebasa.
Yepamusoro-tembiricha superconducting magineti levitation itekinoroji inoshandisa iyo magineti inoyerera pinning hunhu hwepamusoro-tembiricha superconducting yakawanda zvinhu kuti uwane yakagadzikana levitation pasina inoshanda kutonga.
Iyo Liquid Nitrogen Inozadza Rori
Iyo yemvura nitrogen inozadza rori chigadzirwa chakagadzirwa uye chakagadziridzwa naSichuan Haishengjie Cryogenic Technology Co., Ltd. chepamusoro-tembiricha superconducting high-speed maglev project.Ndiwo musimboti we maglev tekinoroji-Dewar inowedzera mvura nitrogen.
