Ipayipi elifakwe ku-vacuum. Inselelo yokugcina lezi ziphuzo ezindaweni zokushisa eziphansi kakhulu ngaphandle kokudluliswa okuthe xaxa kuxazululwa kusetshenziswa ubuchwepheshe be-vacuum insulation. Le bhulogi izochaza kanjani Ipayipi elifakwe ku-vacuumInikeza ukufakwa okushisayo kanye nokubaluleka kwalo ezimbonini ezincike ezinhlelweni ze-cryogenic.

Yini aIpayipi elifakwe ku-vacuum?

A Ipayipi elifakwe ku-vacuumKuqukethe amapayipi amabili agxile: ipayipi elingaphakathi elithwala uketshezi lwe-cryogenic kanye nepayipi elingaphandle elifaka ipayipi elingaphakathi. Isikhala phakathi kwalawa mapayipi amabili sikhishwa ukudala i-vacuum, esebenza njenge-insulator esebenza kahle kakhulu ye-thermal. I-vacuum inciphisa ukudluliswa kokushisa ngokutholwa kanye ne-convection, okusiza ukugcina uketshezi lokushisa okuphansi okuphansi.

Isebenza kanjani ukufakwa kwe-vacuum

Isihluthulelo sokusebenza kahle kwe-aIpayipi elifakwe ku-vacuum ungqimba lwe-vacuum. Ukudluliswa kokushisa kuvame ukwenzeka ngezinqubo ezintathu eziphambili: ukuhunyushwa, ukuxhuma, kanye nemisebe. I-vacuum isusa ukuhunyushwa kanye ne-convection ngoba awekho ama-molecule endiza esikhaleni phakathi kwamapayipi okudlulisa ukushisa. Ngaphezu kwe-vacuum, ipayipi livame ukufaka ukuvikelwa okubonakalayo ngaphakathi kwesikhala se-vacuum, kunciphisa ukudluliswa kokushisa ngemisebe.

NgobaniIpayipi elifakwe ku-vacuum Kubalulekile ngezinhlelo ze-crygenic

Uketshezi lwe-Cryogenic luzwela ngisho nasekwenyuseni okuncane ekushiseni, okungabangela ukuba bahlele, okuholele ekulahlekelweni komkhiqizo kanye nezingozi ezingaba khona.Ipayipi elifakwe ku-vacuumIqinisekisa ukuthi amazinga okushisa e-crygenic fluids ake LNG, LH2, noma i-LN2 ahlala ezinzile ngesikhathi sokuhamba. Lokhu kunciphisa kakhulu ukwakheka kwegesi ye-Bil-off (BOG), kugcina uketshezi esimweni salo osifunayo ngezikhathi ezengeziwe.

Izicelo zeIpayipi elifakwe ku-vacuum

Ipayipi elifakwe ku-vacuumisetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi amandla, i-aerospace, kanye nezinkundla zezokwelapha. Embonini ye-LNG, ama-VIP aqashwa ukudlulisa igesi yemvelo yemvelo phakathi kwamathangi okugcina kanye nama-terminals ngokulahleka okuncane okushisayo. Emkhakheni we-Aerospace, ama-VIP aqinisekisa ukudluliswa okuphephile kwe-hydrogen ewuketshezi, ebalulekile ebalulekile ye-rocket propulsion. Ngokufanayo, ekunakekelweni kwezempilo, i-nitrogen ewuketshezi ihanjiswa kusetshenziswa ama-veps ukugcina izinto zebhayoloji nokusekelwa kwezicelo zezokwelapha.

Isiphetho: ukusebenza kweIpayipi elifakwe ku-vacuum

Indima yeIpayipi elifakwe ku-vacuum Ezokuhamba ngotshwala zeCrygenic azikwazi ukweqiwa. Ngokunciphisa ukudluliselwa kokushisa ngezindlela ezithuthukile zokufakwa kwezindawo zokufaka, ama-VIP aqinisekisa ukuthuthwa okuphephile futhi okusebenzayo koketshezi lwe-cryogenic, okwenza babe balulekile kwizimboni ezincike ebuchwepheshe bokushisa okuphansi. Njengoba isidingo sezicelo ze-crygenic zikhula, ukubaluleka kweI-Vacuum Insurated PipesSizoqhubeka nokukhuphuka, ukuqinisekisa ukusebenza kahle kwe-Thermal kanye nokuphepha emisebenzini ebucayi.
