Umbhobho ogqunywe nge-vacuum(VIP) bubuchwepheshe obubalulekileyo obusetyenziswa kumashishini afuna ukuthuthwa kwezinto ezibangela i-cryogenic liquids, ezifana negesi yendalo enyibilikisiweyo (LNG), i-nitrogen engamanzi (LN2), kunye ne-hydrogen engamanzi (LH2). Le blog ihlola okoumbhobho ogqunyiweyo we-vacuumyintoni, indlela esebenza ngayo, kunye nesizathu sokuba ibalulekile kwiintlobo ngeentlobo zezicelo zoshishino.

Yintoni i Umbhobho ogqunywe nge-vacuum?

Aumbhobho ogqunyiweyo we-vacuum yinkqubo ekhethekileyo yemibhobho eyenzelwe ukuthutha ulwelo oluyi-cryogenic ngelixa inciphisa ukulahleka kobushushu. Le mibhobho yakhiwe ngeengqimba ezimbini ezixineneyo: umbhobho wangaphakathi othwala ulwelo oluyi-cryogenic kunye nombhobho wangaphandle owujikelezileyo. Isithuba esiphakathi kwezi ngqimba zimbini siyasuswa ukuze kwenziwe i-vacuum, esebenza njengesigqubutheli sobushushu. Olu yilo lunceda ukuthintela ukudluliselwa kobushushu ngokuhambisa kunye nokuhambisa, ukugcina ulwelo oluyi-cryogenic kubushushu balo obuphantsi.

Iyenza njani i Umbhobho ogqunywe nge-vacuum Umsebenzi?

Indlela ephambili yokukhusela ubushushu yeumbhobho ogqunyiweyo we-vacuumyivacuum ngokwayo. Kwiimeko eziqhelekileyo, ukudluliselwa kobushushu kwenzeka ngokuqhuba, ukujikelezisa umoya, kunye nemitha. Ngokwenza ivacuum phakathi kwemibhobho yangaphakathi neyangaphandle, i-VIP isusa ukujikelezisa umoya kunye nokujikelezisa umoya, njengoko kungekho zimolekyuli zomoya zokuthwala ubushushu. Ukunciphisa ngakumbi ukudluliselwa kobushushu ngemitha, iinkqubo ze-VIP zihlala ziquka izikhuselo ezikhanyayo ngaphakathi kwendawo yevacuum. Olu dibaniso lwe-vacuum insulation kunye nezithintelo ezikhanyayo lwenzaumbhobho ogqunyiweyo we-vacuumisebenza kakuhle kakhulu ekugcineni ubushushu be-cryogenic fluids.

Izicelo ze Umbhobho ogqunywe nge-vacuum

Umbhobho ogqunywe nge-vacuumisetyenziswa kakhulu kumashishini axhomekeke kubuchwepheshe be-cryogenic, njengamandla, i-aerospace, kunye nokhathalelo lwempilo. Kwicandelo lamandla, ii-VIP zibalulekile ekuthuthweni kwe-LNG, ipetroli ecocekileyo ekufuneka igcinwe kumaqondo obushushu aphantsi njenge--162°C (-260°F). Ii-VIP zikwadlala indima ebalulekileyo ekuthuthweni kwe-hydrogen engamanzi, esetyenziswa kwizicelo zeenqwelo moya kwaye ibonwa njengepetroli enokubakho kwixesha elizayo lamandla acocekileyo. Kwinkonzo yezempilo, i-nitrogen engamanzi ethuthwa nge-VIP isetyenziselwa iinjongo zonyango ezifana nokugcinwa kwe-cryopreservation kunye nonyango lomhlaza.

Iingenelo ze Umbhobho ogqunywe nge-vacuum

Inzuzo ephambili yokusebenzisaumbhobho ogqunyiweyo we-vacuumyikhono layo lokunciphisa ilahleko yobushushu ngexesha lokuthuthwa kolwelo oluyi-cryogenic. Oku kukhokelela ekusebenzeni ngcono, ukwehla kokwakheka kwegesi ebilayo (BOG), kunye nokonga iindleko ngokubanzi kumashishini axhomekeke kwiindawo ezizinzileyo zobushushu obuphantsi. Ukongeza, iinkqubo ze-VIP zibonelela ngokuthembeka kwexesha elide, zigcina ukusebenza kwe-insulation ixesha elide ngaphandle kokugcinwa kakhulu.

Isiphelo: Ukubaluleka kwe Umbhobho ogqunywe nge-vacuum

Umbhobho ogqunywe nge-vacuumbubuchwepheshe obubalulekileyo kumashishini aphatha ulwelo oluyi-cryogenic. Ngokuthintela ukudluliselwa kobushushu kunye nokugcina amaqondo obushushu aphantsi afunekayo kwizinto ezifana ne-LNG kunye ne-hydrogen engamanzi, ii-VIP zinceda ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokusebenza kakuhle kweendleko kwiinkqubo ezibalulekileyo zoshishino. Njengoko imfuno yezicelo ze-cryogenic ikhula,umbhobho ogqunyiweyo we-vacuumiza kuqhubeka nokuba sisisombululo esibalulekileyo ekuthuthweni kolwelo olushushu kakhulu.
