Vacuum Insulated Umbhobho
I-Vacuum Insulated Pipe (i-VIP), eyaziwa ngokuba yi-Vacuum Jacketed Pipe (VJP), iyinxalenye ebalulekileyo yokunciphisa ukufumana ubushushu okanye ilahleko ngexesha lokugqithiswa kolwelo lwe-cryogenic kunye nezinye izinto ezithintela ubushushu. Ukusebenza kwayo okuphezulu kwe-thermal kunciphisa iindleko zokusebenza kunye nokwandisa inkqubo yokusebenza kakuhle. Yenzelwe ukuhlanganiswa okungenamthungo kunye nezixhobo ezikhoyo ze-cryogenic kunye nokuhambelana ne-Vacuum Insulated Hoses (VIHs), i-Vacuum Insulated Pipe (VIP) iqinisekisa ukusebenza kakuhle kunye nokuthembeka kuzo zonke izicelo ezahlukeneyo. Ezi zikwanyusa ukusebenza kwezixhobo ze-cryogenic ngokunciphisa inkunkuma!
Izicelo eziphambili:
- I-Cryogenic Liquid Transfer: I-Vacuum Insulated Pipe (VIP), okanye i-Vacuum Jacketed Pipe (VJP), idlulisela ngokufanelekileyo i-nitrogen engamanzi, i-oksijini yolwelo, i-argon yolwelo, kunye nolunye ulwelo lwe-cryogenic ngelixa unciphisa ukubilisa. Oku kunceda ukunciphisa iindleko zamandla. Olu lwelo lunokuhanjiswa ngoncedo lwe-Vacuum Insulated Hoses (VIHs).
- I-LNG / CNG Transfer and Distribution: Ibalulekile ekukhuselweni okukhuselekileyo nokufanelekileyo kwe-liquefied natural gas (LNG) kunye ne-compressed natural gas (CNG) ngexesha lokuthutha nokusabalalisa. Umbhobho weVacuum Insulated wanamhlanje (VIP) uhambelana neemfuno ezingqongqo zanamhlanje.
- I-Pharmaceutical Manufacturing: Ukugcina ulawulo oluchanekileyo lokushisa kubalulekile kwimveliso yamayeza. I-Vacuum Insulated Pipe (VIP), okanye i-Vacuum Jacketed Pipe (VJP) iqinisekisa ukuhanjiswa okuzinzile kwezinto ezithintekayo kwiqondo lokushisa. Iimpawu zeqondo lokushisa zinokwandiswa kunye ne-Vacuum Insulated Hoses (VIHs).
- Ukulungiswa kokutya kunye nokugcinwa: Inkqubo inokugcinwa ngokufanelekileyo kwiqondo lokushisa elibandayo ngoncedo lweenkqubo ze-HL Cryo. Ukulawula ukushisa okuchanekileyo kunceda ukugcina ukusebenza okuphezulu. Ezi zisoloko ziqhagamshelwe kwi-Vacuum Insulated Pipe (VIP).
- I-Aerospace kunye noPhando: I-Vacuum Insulated Pipe (VIP) isekela uphando oluphezulu kunye nophuhliso kwi-aerospace, i-particle physics, kunye nezinye iindawo apho ukushisa okukhulu kubandakanyeka khona, okunokuphuculwa kunye ne-Vacuum Insulated Hoses (VIHs). Ezi kufuneka zisebenze kumanqanaba aphezulu kunye nokusebenza kweVacuum Insulated Pipe (VIP).
I-Vacuum Insulated Pipe (VIP), ebizwa ngokuba yi-Vacuum Jacketed Pipe (VJP), esuka kwi-HL Cryogenics iyona nto ibhetele ekusebenzeni kwe-thermal kunye nokuthembeka kokudluliselwa kwe-cryogenic fluid. Ifanelekile kuluhlu olubanzi lwezicelo.
