M'mawa pa Januware 13, 2021, mzere woyamba padziko lonse waukadaulo wothamanga kwambiri wothamanga kwambiri wa maglev pogwiritsa ntchito ukadaulo woyambirira wa University of Southwest Jiaotong unakhazikitsidwa ku Chengdu, m'chigawo cha Sichuan, China.Zikuwonetsa zopambana kuyambira pachiyambi pakufufuza kwa projekiti yotentha kwambiri ya superconducting high speed maglev ku China ndipo dziko lathu lili ndi zoyeserera zaukadaulo ndi ziwonetsero.
Mlandu Woyamba Padziko Lapansi; Pangani Chitsanzo
Kutumizidwa kwa mzere woyesera waukadaulo wa superconducting maginito ndi woyamba padziko lapansi.Ndi woimira kupanga wanzeru ku China ndipo adapanga chitsanzo pankhani ya kutentha kwapamwamba kwambiri.
Ukadaulo wapamtunda wotentha kwambiri wa superconducting maglev uli ndi zabwino zopanda kukhazikika kwa gwero, mawonekedwe osavuta, kupulumutsa mphamvu, kuwononga mankhwala ndi phokoso, chitetezo ndi chitonthozo, komanso mtengo wotsika mtengo. madera osiyanasiyana othamanga, makamaka oyenera kugwiritsa ntchito mizere yothamanga kwambiri komanso yothamanga kwambiri;Ukadaulo uwu ndiukadaulo wapamwamba kwambiri wa superconducting maglev wodziyimira pawokha, wodziwongolera, komanso wokhazikika.Ndi njira yatsopano yoyendera njanji yomwe ikuyang'anizana ndi chitukuko chamtsogolo komanso chiyembekezo chogwiritsa ntchito kwambiri. Ukadaulowu umayamba kupangidwa m'malo amlengalenga, ndipo liwiro loyembekezeka loyendetsa ntchito ndi lalikulu kuposa 600 km / h, zomwe zikuyembekezeka kupanga zatsopano. mbiri ya liwiro la magalimoto pamtunda mumlengalenga.
Chotsatira ndikuphatikiza ukadaulo wa mapaipi a vacuum wamtsogolo kuti apange njira yoyendera yokwanira yomwe imadzaza mipata yamayendedwe akumtunda komanso kuthamanga kwamayendedwe apamlengalenga, zomwe zidzakhazikitse maziko akuyenda kwanthawi yayitali pa liwiro lopitilira 1000 km / h, potero kumanga mtundu watsopano wamayendedwe apamtunda.Kusintha koyang'ana kutsogolo komanso kosokoneza pakukula kwa njanji.

Magnetic Levitation Technology
Pakali pano, pali atatu "super magnetic Levitation" matekinoloje mu dziko.
Tekinoloje yamagetsi yamagetsi ku Germany:
Mfundo ya electromagnetic imagwiritsidwa ntchito kuzindikira mayendedwe pakati pa sitima ndi njanji.Pakali pano, sitima yapamtunda ya Shanghai maglev, sitima ya maglev yomwe ikumangidwa ku Changsha ndi Beijing zonse zili mu sitimayi.
Ukadaulo wocheperako waku Japan wa superconducting maginito levitation:
Gwiritsani ntchito mphamvu zopangira zinthu zina pa kutentha kochepa (kuzizira mpaka -269 ° C ndi helium yamadzimadzi) kuti sitimayi ikhale yotsika, monga Shinkansen maglev line ku Japan.
Ukadaulo wapamwamba kwambiri waku China wa superconducting maginito levitation:
Mfundoyi ndi yofanana ndi ya kutentha kwapamwamba kwambiri, koma kutentha kwake ndi -196 ° C.
M'mayesero am'mbuyomu, kutsika kwa maginito m'dziko lathu sikungoyimitsidwa komanso kuyimitsidwa.
△ Nayitrogeni wamadzimadzi ndi ma superconductors △
Ubwino wa High Temperature Superconducting Maglev Sitimayi
Kupulumutsa mphamvu:Kuwongolera ndi kuwongolera sikufuna kuwongolera mwachangu kapena magetsi agalimoto, ndipo dongosololi ndi losavuta.Kuyimitsidwa ndi kuwongolera kumangofunika kuzizidwa ndi nayitrogeni wamadzi wotchipa (77 K), ndipo 78% ya mpweya ndi nitrogen.
Chitetezo cha chilengedwe:The mkulu-kutentha superconducting maginito levitation akhoza levitation statically, kwathunthu popanda phokoso;njanji ya maginito yokhazikika imapanga mphamvu ya maginito yosasunthika, ndipo mphamvu ya maginito pamalo pomwe okwera amakhudza ndi ziro, ndipo palibe kuipitsidwa ndi ma elekitiroma.
Liwilo lalikulu:Kutalika kwa levitation (10 ~ 30 mm) kumatha kupangidwa momwe kumafunikira, ndipo chitha kugwiritsidwa ntchito kuthamanga kuchokera ku static kupita kutsika, sing'anga, kuthamanga kwambiri komanso kuthamanga kwambiri.Poyerekeza ndi matekinoloje ena a maginito a levitation, ndi abwino kwambiri pamayendedwe a vacuum (kuposa 1000 km / h).
Chitetezo:Mphamvu yowongolera imakula mokulirapo ndi kuchepa kwa kutalika kwa levitation, ndipo chitetezo chachitetezo chimatha kutsimikizika popanda kuwongolera kolunjika.Dongosolo lodziwongolera lokhazikika limathanso kuwonetsetsa kuti ntchito yotetezeka ikuyendera njira yopingasa.
Chitonthozo:"Mphamvu ya pinning" yapadera ya superconductor yotentha kwambiri imapangitsa kuti thupi la galimoto likhale lokhazikika mmwamba ndi pansi, lomwe ndi lokhazikika lomwe ndi lovuta kuti galimoto iliyonse ikwaniritse.Zomwe okwera amakumana nazo akakwera ndi "kusamva".
Mtengo wotsika:Poyerekeza ndi German mosalekeza-conductivity maginito levitation magalimoto ndi Japanese otsika kutentha superconducting maginito levitation magalimoto ntchito madzi helium, ili ndi ubwino wopepuka kulemera, kapangidwe yosavuta, ndi otsika kupanga ndi ntchito ndalama.
Scientific and Technological Application of Liquid Nitrogen
Chifukwa cha mawonekedwe a superconductors, superconductor iyenera kumizidwa m'malo a nayitrogeni amadzimadzi pa -196 ℃ panthawi yantchito.
High-temperature superconducting maginito levitation ndi teknoloji yomwe imagwiritsa ntchito maginito pinning makhalidwe apamwamba-kutentha superconducting chochulukira zipangizo kukwaniritsa khola levitation popanda kulamulira yogwira.
