Njengoba izimboni ziqhubeka nokuhlola izixazululo zamandla ahlanzekile, i-liquid hydrogen (LH2) iye yavela njengomthombo othembisayo kaphethiloli wezinhlelo eziningi ezihlukahlukene. Kodwa-ke, ukuthuthwa nokugcinwa kwe-hydrogen ewuketshezi kudinga ubuchwepheshe obuthuthukisiwe ukuze kugcinwe isimo sayo se-cryogenic. Obunye ubuchwepheshe obubalulekile kule ndawo yi-ipayipi le-vacuum jacketed, edlala indima ebalulekile ekuqinisekiseni ukudluliswa okuphephile nokuphumelelayo kwe-hydrogen enguketshezi ebangeni elide.
Ukuqonda Amapayipi Afakwe Ijakhethi Yevacuum
Vacuum amapayipi anejakhethi(VJP) amapayipi akhethekile aklanyelwe ukuthutha uketshezi lwe-cryogenic, njenge-hydrogen enguketshezi, kuyilapho enciphisa ukudluliswa kokushisa. Lawa mapayipi ahlanganisa ipayipi elingaphakathi, eliphethe uketshezi lwe-cryogenic, kanye nongqimba olungaphandle lwe-vacuum-insulated olusebenza njengesithiyo esishisayo. I-vacuum ephakathi kwezingqimba zangaphakathi nezingaphandle ibalulekile ekwehliseni ukugcwala kokushisa nokugcina izinga lokushisa eliphansi elidingekayo ukuze i-hydrogen enguketshezi ihlale isesimweni sayo se-cryogenic.
Isidingo Sokufakwa Kwamandla Okusebenzayo Ekuthuthweni Kwe-Liquid Hydrogen
I-hydrogen ewuketshezi idinga ukugcinwa emazingeni okushisa aphansi kakhulu (cishe -253°C noma -423°F). Noma yikuphi okokufaka okushisa, ngisho nangamanani amancane, kungabangela ukuhwamuka, okuholela ekulahlekelweni kwevolumu nokusebenza kahle. Iipayipi le-vacuum jacketediqinisekisa ukuthi i-hydrogen ewuketshezi ihlala ezingeni lokushisa oyifunayo, ivimbele ukuhwamuka okungadingekile futhi iqinisekise ukuthi i-hydrogen ihlala isesimweni esiwuketshezi isikhathi eside. Lokhu kufakela okusebenza kahle kakhulu kubalulekile ezinhlelweni ezinjengamasistimu okulethwa kukaphethiloli okuhlola indawo, izimoto ezisebenza nge-hydrogen, kanye nokusetshenziswa kwezimboni.
Izinzuzo ze-Vacuum Jacketed Pipes ku-Cryogenic Applications
Enye yezinzuzo ezibalulekile zevacuum jacketed amapayipiekuthuthweni kwe-hydrogen ewuketshezi amandla azo okunciphisa ukuzuza kokushisa ngaphandle kokuthembela ezintweni zokuvikela ezinkulu noma ezingenakwenzeka. Lokhu kubenza babe yisixazululo esifanelekile sezinhlelo zokusebenza ezidinga amasistimu ahlangene, athembekile, futhi angabizi kakhulu. Ukwengeza, ukumelana nokushisa okuphezulu okuhlinzekwa yi-vacuum insulation kuqinisekisa indawo ezinzile nephephile yokugcina nokudluliselwa kwe-hydrogen ewuketshezi, ngisho nasezimweni zangaphandle eziyinselele.
Ikusasa lamapayipi anejakhethi ye-Vacuum kungqalasizinda ye-Hydrogen
Njengoba isidingo se-hydrogen sikhula, ikakhulukazi kumongo wokuguqulwa kwamandla, indima yevacuum jacketed amapayipikungqalasizinda ye-hydrogen ewuketshezi izokhula kuphela. Ukuqamba okusha ekwakhiweni kwamapayipi, okufana nezinto ezithuthukisiwe zokugqumisa kanye nobuchwepheshe obuthuthukisiwe bokungavuzi, kuzoqhubeka nokuthuthukisa ukusebenza kahle nokuthembeka kwalezi zinhlelo. Eminyakeni ezayo, singalindelavacuum jacketed amapayipiukudlala indima ebaluleke nakakhulu ekulolongeni ikusasa lokugcinwa nokusabalalisa i-hydrogen.
Ekuphetheni,vacuum jacketed amapayipizibalulekile ekuthuthweni okuphephile nokusebenzayo kwe-liquid hydrogen. Njengoba amandla e-hydrogen eqhubeka nokudlondlobala emhlabeni wonke, lawa mapayipi asethuthukile azoba yingxenye yokuxhasa ingqalasizinda edingekayo ukuze kulethwe izixazululo zamandla ahlanzekile, nezimeme.
