Vacuum insulated umbhobho(VIP) licandelo elibalulekileyo ekuthuthweni kwe-cryogenic liquids, njenge-liquefied natural gas (LNG), i-liquid hydrogen (LH2), kunye ne-nitrogen engamanzi (LN2). Umceli mngeni wokugcina olu lwelo kumaqondo obushushu aphantsi kakhulu ngaphandle kokudluliselwa kobushushu okubalulekileyo kusonjululwa kusetyenziswa itekhnoloji yokugquma ivacuum. Le bhlog iya kuchaza ukuba njani vacuum insulated umbhobhoibonelela nge-thermal insulation kunye nokubaluleka kwayo kumashishini axhomekeke kwiinkqubo ze-cryogenic.

Yintoni aVacuum Insulated Pipe?

A vacuum insulated umbhobhoiqulethe imibhobho emibini egxininisekile: umbhobho ongaphakathi ophethe ulwelo lwe-cryogenic kunye nombhobho wangaphandle ovale umbhobho ongaphakathi. Isithuba esiphakathi kwale mibhobho mibini siyakhutshwa ukuze kwenziwe ivacuum, esebenza njengesithinteli sobushushu esisebenza kakhulu. Ivacuum inciphisa ukuhanjiswa kobushushu ngokuqhuba kunye ne-convection, enceda ukugcina ulwelo kwiqondo lobushushu elifunekayo.

Isebenza njani iVacuum Insulation

Isitshixo ekusebenzeni kakuhle kwe-thermal avacuum insulated umbhobho ngumaleko wevacuum. Ukugqithiswa kobushushu ngokuqhelekileyo kwenzeka ngeenkqubo ezintathu eziphambili: ukuqhuba, ukuhanjiswa, kunye nemitha. I-vacuum iphelisa ukuqhutyelwa kunye nokuhamba ngenxa yokuba akukho zimolekyuli zomoya kwindawo phakathi kwemibhobho yokudlulisa ubushushu. Ukongeza kwi-vacuum, umbhobho uhlala ubandakanya ukukhuselwa okubonakalayo ngaphakathi kwendawo ye-vacuum, ukunciphisa ukuhanjiswa kobushushu nge-radiation.

NgobaVacuum Insulated Pipe Ibalulekile kwiiNkqubo zeCryogenic

Ulwelo lwe-Cryogenic lunovelwano nokunyuka okuncinci kwamaqondo obushushu, nto leyo enokubangela ukuba ibe ngumphunga, nto leyo ekhokelela ekulahlekeni kwemveliso kunye neengozi ezinokubakho.Vacuum insulated umbhobhoiqinisekisa ukuba ubushushu be-cryogenic fluids njenge-LNG, LH2, okanye i-LN2 buhlala buzinzile ngexesha lokuthutha. Oku kunciphisa kakhulu ukubunjwa kwe-boil-off gas (BOG), ukugcina ulwelo kwimeko yalo efunekayo ixesha elide.

Usetyenziso lweVacuum Insulated Pipe

Vacuum insulated umbhobhoisetyenziswa kumashishini ahlukeneyo, kuquka amandla, i-aerospace, kunye nezonyango. Kwishishini le-LNG, ii-VIP ziqeshwe ukudlulisa igesi yendalo engamanzi phakathi kwamatanki okugcina kunye neetheminali kunye nelahleko encinci ye-thermal. Kwicandelo le-aerospace, i-VIPs iqinisekisa ukuhanjiswa okukhuselekileyo kwe-hydrogen engamanzi, ibalulekile kwi-rocket propulsion. Ngokufanayo, kukhathalelo lwempilo, i-nitrogen engamanzi ithuthwa kusetyenziswa ii-VIPs ukugcina izinto zebhayoloji kunye nokuxhasa izicelo zonyango.

Isiphelo: Ukusebenza kakuhle kweVacuum Insulated Pipe

Indima yevacuum insulated umbhobho kuthutho lwe-cryogenic liquid ayinakugqithiswa. Ngokunciphisa ukuhanjiswa kobushushu ngeendlela eziphambili zokugquma, ii-VIPs ziqinisekisa ukuthuthwa okukhuselekileyo kunye nokuhamba kakuhle kwe-cryogenic liquids, okwenza kube yinto ebalulekileyo kumashishini axhomekeke kubuchwepheshe obuphantsi. Njengoko imfuno yezicelo ze-cryogenic ikhula, ukubaluleka kwevacuum insulated imibhobhoiya kuqhubeka nokunyuka, ukuqinisekisa ukusebenza kakuhle kwe-thermal kunye nokhuseleko kwimisebenzi ebalulekileyo.
