Ma ke kakahiaka o Ianuali 13, 2021, ua hoʻolauna mua ʻia ka superconducting superconducting high-speed maglev engineering prototype a me ka laina hoʻāʻo e hoʻohana ana i ka ʻenehana mua o Southwest Jiaotong University ma Chengdu, Sichuan Province, Kina.He hōʻailona ia i kahi holomua mai ka ʻohi ʻana i ka noiʻi ʻana o ke kiʻekiʻe wela superconducting kiʻekiʻe wikiwiki maglev papahana ma Kina a me ko mākou ʻāina i nā kūlana no ka hoʻokolohua ʻenekinia a me nā hōʻike.
ʻO ka hihia mua ma ka honua; e hana i mua
ʻO ke kauoha ʻana i ka laina hoʻāʻo ʻenehana levitation magnetic superconducting kiʻekiʻe ka mea mua ma ka honua.He ʻelele ia o ka hana akamai a Kina a hana i kahi precedent ma ke kahua o ka superconductivity kiʻekiʻe.
ʻO ka ʻenehana kaʻaahi superconducting superconducting maglev ka maikaʻi o ka ʻole kumu kumu, ke ʻano maʻalahi, ka mālama ʻana i ka ikehu, ʻaʻohe kemika a me ka leo pollution, palekana a me ka hōʻoluʻolu, a me ka uku hana haʻahaʻa. ʻokoʻa o nā kikowaena wikiwiki, kūpono loa no ka hana ʻana o nā laina kiʻekiʻe a me nā laina ultra-kiʻekiʻe;ʻO kēia ʻenehana kahi ʻenehana superconducting superconducting maglev train me ka hoʻokuʻu ʻana iā ia iho, alakaʻi ponoʻī, a me nā hiʻohiʻona paʻa ponoʻī.He ala kaʻa kaʻa maʻamau hou ia e kū nei i ka hoʻomohala ʻana i ka wā e hiki mai ana a me nā prospects noi ākea. ʻO ka ʻenehana mua e hana ʻia i loko o ka lewa, a ʻoi aku ka nui o ka waiwai o ka wikiwiki o ka hana ma mua o 600 km / h, i manaʻo ʻia e hana i kahi hou. hoʻopaʻa moʻolelo no ka wikiwiki o ke kaʻa ʻana i ka ʻāina ma kahi kaiapuni lewa.
ʻO ka hana aʻe, ʻo ia ka hoʻohui ʻana i ka ʻenehana pipeline vacuum e hiki mai ana e hoʻomohala i kahi ʻōnaehana holoʻokoʻa e hoʻopiha ai i nā āpau o ka lawe ʻana i ka ʻāina a me ka wikiwiki o ka lawe ʻana i ka ea, kahi e hoʻokumu ai i ke kumu no kahi holomua lōʻihi i nā wikiwiki ma luna o 1000 km / h, a laila kūkulu i kahi kumu hoʻohālike hou o ka halihali ʻāina.Nā hoʻololi ʻana i mua a me nā hoʻololi i ka hoʻomohala ʻana i ke kaʻa kaʻaahi.

ʻenehana Levitation Magnetic
I kēia manawa, ʻekolu mau ʻenehana "super magnetic levitation" i ka honua.
ʻenehana levitation electromagnetic ma Kelemānia:
Hoʻohana ʻia ka loina electromagnetic e ʻike i ka levitation ma waena o ke kaʻaahi a me ke ala.I kēia manawa, ʻo ke kaʻaahi maglev Shanghai, ke kaʻaahi maglev e kūkulu ʻia ana ma Changsha a me Beijing aia i loko o kēia kaʻaahi.
ʻO ka ʻenehana levitation magnetic superconducting haʻahaʻa haʻahaʻa o Iapana:
E hoʻohana i nā waiwai superconducting o kekahi mau mea ma nā haʻahaʻa haʻahaʻa (hoʻoluʻu i -269°C me ka helium wai) e hoʻoneʻe ai ke kaʻaahi, e like me ka laina Shinkansen maglev ma Iapana.
ʻO ka ʻenehana levitation magnetic superconducting kiʻekiʻe o Kina:
ʻO ke kumumanaʻo ka mea like me ka superconductivity haʻahaʻa haʻahaʻa, akā ʻo kona mahana hana -196 ° C.
I nā hoʻokolohua mua, ʻaʻole hiki ke hoʻokuʻu wale ʻia kēia levitation magnetic i ko mākou ʻāina akā ua hoʻokuʻu ʻia hoʻi.
△ Naikokene wai a me nā superconductors △
ʻO nā pono o ke kaʻaahi Maglev Superconducting High Temperature
Mālama i ka ikehu:ʻAʻole pono ka Levitation a me ke alakaʻi ʻana i ka mana ikaika a i ʻole ka lako mana kaʻa, a maʻalahi ka ʻōnaehana.ʻO ka hoʻokuʻu ʻia a me ke alakaʻi ʻana e hoʻoluʻu wale ʻia me ka wai hauʻoli (77 K), a ʻo 78% o ka ea he nitrogen.
Palekana kaiapuni:ʻO ka levitation magnetic superconducting kiʻekiʻe hiki ke levitation statically, piha me ka walaʻau ʻole;ʻO ka track magnet paʻa e hoʻohua i kahi māla magnetic static, a ʻo ke kahua magnetic ma kahi e hoʻopā ai ka poʻe kaʻa he zero, a ʻaʻohe pollution electromagnetic.
Ka māmā holo kiʻekiʻe:Hiki ke hoʻolālā ʻia ke kiʻekiʻe levitation (10~30 mm) e like me ka mea e pono ai, a hiki ke hoʻohana ʻia e holo mai ka static a haʻahaʻa, waena, kiʻekiʻe a me ka ultra-kiʻekiʻe.Ke hoʻohālikelike ʻia me nā ʻenehana levitation magnetic, ʻoi aku ka maikaʻi no ka lawe ʻana i ka pipeline vacuum (ʻoi aku ma mua o 1000 km / h).
Palekana:Hoʻonui nui ʻia ka ikaika levitation me ka emi ʻana o ke kiʻekiʻe o ka levitation, a hiki ke hōʻoia ʻia ka palekana o ka hana me ka ʻole o ka mana i ka ʻaoʻao kū.Hiki i ka ʻōnaehana alakaʻi hoʻoikaika ponoʻī ke hōʻoia i ka hana palekana ma ka ʻaoʻao ākea.
Hōʻoluʻolu:ʻO ka "pinning force" kūikawā o ka superconductor wela kiʻekiʻe e mālama i ke kino o ke kaʻa i luna a i lalo, ʻo ia kahi paʻa paʻakikī no kekahi kaʻa e hoʻokō.ʻO ka mea e ʻike ai ka poʻe kaʻa i ka wā e holo ana ʻo "ka manaʻo o ka manaʻo ʻole".
Uku hana haahaa:Ke hoʻohālikelike ʻia me nā kaʻa levitation magnetic mau-conductivity a me Iapana haʻahaʻa haʻahaʻa superconducting magnetic levitation kaʻa me ka hoʻohana ʻana i ka helium wai, loaʻa iā ia nā mea maikaʻi o ke kaumaha māmā, ka hana maʻalahi, a me nā kumukūʻai haʻahaʻa a me ka hana.
Hoʻohana ʻepekema a me ka ʻenehana o Liquid Nitrogen
Ma muli o nā hiʻohiʻona o nā superconductors, pono e hoʻokomo ʻia ka superconductor i loko o kahi kaila nitrogen wai ma -196 ℃ i ka wā o ka hana.
ʻO ka levitation magnetic superconducting kiʻekiʻe he ʻenehana e hoʻohana i nā hiʻohiʻona pinning flux magnetic o nā mea nui superconducting kiʻekiʻe e hoʻokō i ka levitation paʻa me ka ʻole o ka mana ikaika.
ʻO ka Liquid Nitrogen Filling Truck
ʻO ke kaʻa hoʻopiha piha wai wai he huahana i hoʻolālā ʻia a hoʻomohala ʻia e Sichuan Haishengjie Cryogenic Technology Co., Ltd. no ka superconducting superconducting high-speed maglev project. ʻO ia ke kumu o ka ʻenehana maglev-Dewar supplement liquid nitrogen.
△ Ke noi kahua o Liquid Nitrogen Filling Truck △
ʻO ka hoʻolālā kelepona, hiki ke hoʻokō pololei ʻia ka hana hoʻopiha wai nitrogen ma ka ʻaoʻao o ke kaʻaahi.
Hiki i ka semi-automatic liquid nitrogen filling system ke hāʻawi i 6 dewar me ka wai nitrogen i ka manawa like.
ʻEono-ʻaoʻao kūʻokoʻa mana ʻōnaehana, kēlā me kēia awa refill hiki ke hoʻomalu i kēlā me kēia.
Ka pale haʻahaʻa haʻahaʻa, pale i loko o ka Dewar i ka wā o ka hoʻopiha ʻana.
24V pale uila palekana.
Paʻa Paʻa Paʻa Pono
He pahu hoʻolako ponoʻī i hoʻomohala ʻia a hana ʻia no ka mālama ʻana i ka nitrogen wai.Ua hoʻokumu mau ʻia i ka hoʻolālā hoʻolālā palekana, ka maikaʻi o ka hana ʻana a me nā lā mālama lōʻihi o ka wai nitrogen.

Ke holo nei ka papahana
I kekahi mau lā i hala aku nei, ua hana pū mākou me nā poʻe loea mai ke Kulanui o Southwest Jiaotong University
Lawe ʻia ka hana noiʻi ma hope o ka papahana superconducting superconducting high-speed maglev
△ Kahua Seminar △
Hoʻohanohano nui mākou i ka hiki ke komo i kēia hana paionia i kēia manawa.I ka wā e hiki mai ana, e hoʻomau nō hoʻi mākou i ka hana pū ʻana me ka hana noiʻi hope o ka papahana e hana i kēlā me kēia pae i mua no kēia hana paionia.
Manaʻo mākou
E holomua ana ka ʻepekema a me ka ʻenehana o Kina
Ua piha ka wā e hiki mai ana o Kina i nā manaʻolana
