Vacuum insulated ipayipi(VIP) ubuchwepheshe obubalulekile obusetshenziswa ezimbonini ezidinga ukuthuthwa koketshezi lwe-cryogenic, olufana negesi yemvelo engamanzi (LNG), i-liquid nitrogen (LN2), ne-liquid hydrogen (LH2). Le bhulogi ihlola ukuthi yinivacuum insulated ipayipiukuthi, isebenza kanjani, futhi kungani ibalulekile ohlotsheni lwezinhlelo zokusebenza zezimboni.

Yini a Vacuum Insulated Pipe?

Avacuum insulated ipayipi iwuhlelo olukhethekile lwamapayipi oluklanyelwe ukuthutha uketshezi lwe-cryogenic kuyilapho kunciphisa ukulahlekelwa okushisayo. Lawa mapayipi akhiwe ngezingqimba ezimbili ezigxilile: ipayipi elingaphakathi elithwala uketshezi lwe-cryogenic kanye nepayipi elingaphandle elilizungezile. Isikhala esiphakathi kwalezi zingqimba ezimbili siyakhishwa ukuze kwakhiwe i-vacuum, esebenza njengesivikelo esishisayo. Lo mklamo usiza ukuvimbela ukudluliswa kokushisa ngokusebenzisa i-conduction kanye ne-convection, ukugcina uketshezi lwe-cryogenic ekushiseni kwalo okuphansi.

Kwenziwa kanjani a Vacuum Insulated Pipe Sebenza?

Indlela yokuqala yokwahlukanisa avacuum insulated ipayipiivacuum ngokwayo. Ezimweni ezijwayelekile, ukudluliswa kokushisa kwenzeka ngokusebenzisa i-conduction, convection, kanye nemisebe. Ngokwenza i-vacuum phakathi kwamapayipi angaphakathi nangaphandle, i-VIP iqeda ukuqhutshwa nokuhamba, njengoba kungekho ama-molecule omoya okuphatha ukushisa. Ukuze kuqhutshekwe nokunciphisa ukudluliswa kokushisa ngemisebe, amasistimu e-VIP ngokuvamile ahlanganisa izihlangu ezikhanyayo ngaphakathi kwesikhala sevacuum. Le nhlanganisela ye-vacuum insulation kanye nezithiyo ezikhanyayo yenzavacuum insulated ipayipiesebenza kahle kakhulu ekugcineni izinga lokushisa le-cryogenic fluids.

Izicelo ze Vacuum Insulated Pipe

Vacuum insulated ipayipiisetshenziswa kakhulu ezimbonini ezithembele kubuchwepheshe be-cryogenic, njengamandla, i-aerospace, nokunakekelwa kwezempilo. Emkhakheni wamandla, ama-VIP abalulekile ekuthutheni i-LNG, uphethiloli ohlanzekile odinga ukugcinwa emazingeni okushisa aphansi afinyelela ku--162°C (-260°F). Ama-VIP aphinde adlale indima ebalulekile ekuthuthweni kwe-hydrogen ewuketshezi, esetshenziswa ekusetshenzisweni kwe-aerospace futhi ibonakala njengophethiloli ongaba khona wekusasa lamandla ahlanzekile. Ekunakekelweni kwezempilo, i-nitrogen ewuketshezi ethuthwa ngama-VIP isetshenziselwa izinjongo zokwelapha ezifana ne-cryopreservation kanye nokwelashwa komdlavuza.

Izinzuzo ze Vacuum Insulated Pipe

Inzuzo eyinhloko yokusebenzisavacuum insulated ipayipiamandla ayo okunciphisa ukulahlekelwa okushisayo ngesikhathi sokuthuthwa kwe-cryogenic fluid. Lokhu kuholela ekusebenzeni okuthuthukisiwe, ukwakheka kwegesi ebilisiwe (i-BOG) encishisiwe, kanye nokonga kwezindleko sezimboni ezincike endaweni ezinzile enezinga lokushisa eliphansi. Ukwengeza, amasistimu e-VIP anikeza ukwethembeka kwesikhathi eside, ukugcina ukusebenza kwe-insulation isikhathi eside ngokulungiswa okuncane.

Isiphetho: Ukubaluleka kwe Vacuum Insulated Pipe

Vacuum insulated ipayipiubuchwepheshe obubalulekile ezimbonini eziphatha uketshezi lwe-cryogenic. Ngokuvimbela ukudluliswa kokushisa nokugcina amazinga okushisa aphansi adingekayo ezintweni ezifana ne-LNG ne-liquid hydrogen, ama-VIP asiza ukuqinisekisa ukuphepha, ukusebenza kahle, kanye nokusebenza ngempumelelo kwezindleko ezinqubweni ezibalulekile zezimboni. Njengoba isidingo sezinhlelo zokusebenza ze-cryogenic sikhula,vacuum insulated ipayipiizoqhubeka nokuba yisixazululo esibalulekile sokuthuthwa koketshezi olunezinga lokushisa eliphansi.
