Vacuum insulated chitoliro(VIP) ndi gawo lofunikira pakunyamula zakumwa za cryogenic, monga gasi wachilengedwe (LNG), liquid hydrogen (LH2), ndi nayitrogeni wamadzimadzi (LN2). Vuto losunga zakumwazi pazitentha zotsika kwambiri popanda kutentha kwambiri zimathetsedwa pogwiritsa ntchito ukadaulo wa vacuum insulation. Blog iyi ifotokoza momwe vacuum insulated chitoliroimapereka kusungunula kwamafuta ndi kufunikira kwake m'mafakitale omwe amadalira machitidwe a cryogenic.

Kodi aVacuum Insulated Pipe?

A vacuum insulated chitoliroimakhala ndi mapaipi awiri okhazikika: chitoliro chamkati chomwe chimanyamula madzi a cryogenic ndi chitoliro chakunja chomwe chimatsekereza chitoliro chamkati. Malo pakati pa mapaipi awiriwa amachotsedwa kuti apange vacuum, yomwe imakhala ngati insulator yotentha kwambiri. Vacuum imachepetsa kutentha kwa mpweya kudzera mu conduction ndi convection, zomwe zimathandiza kuti madzi azikhala ndi kutentha komwe kumafunikira.

Momwe Vacuum Insulation Imagwirira Ntchito

Chinsinsi cha kutentha kwachangu kwa avacuum insulated chitoliro ndi vacuum layer. Kusintha kwa kutentha kumachitika kudzera munjira zitatu zazikulu: conduction, convection, ndi radiation. Vacuum imathetsa kuchititsa ndi kusuntha chifukwa palibe mamolekyu a mpweya pakati pa mapaipi kuti asamutsire kutentha. Kuphatikiza pa vacuum, chitolirocho nthawi zambiri chimaphatikizapo zotchingira zowunikira mkati mwa vacuum, kuchepetsa kutentha kwa kutentha kudzera mu radiation.

Chifukwa chiyani?Vacuum Insulated Pipe Ndiwofunikira pa Cryogenic Systems

Zamadzimadzi za cryogenic zimakhudzidwa ngakhale ndi kutentha pang'ono, komwe kumatha kupangitsa kuti asungunuke, zomwe zimapangitsa kuti zinthu ziwonongeke komanso zoopsa zomwe zingachitike.Vacuum insulated chitoliroamaonetsetsa kuti kutentha kwa madzi a cryogenic monga LNG, LH2, kapena LN2 kumakhalabe kokhazikika panthawi yoyendetsa. Izi zimachepetsa mapangidwe a gasi owiritsa (BOG), kusunga madziwo m'malo omwe amafunikira kwa nthawi yayitali.

Mapulogalamu aVacuum Insulated Pipe

Vacuum insulated chitoliroamagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza mphamvu, zakuthambo, ndi zamankhwala. M'makampani a LNG, ma VIP amagwiritsidwa ntchito kusamutsa gasi wachilengedwe wokhala ndi liquefied pakati pa akasinja osungira ndi ma terminals omwe amatayika pang'ono kutentha. M'gawo lazamlengalenga, ma VIP amawonetsetsa kusamutsidwa kotetezeka kwa hydrogen yamadzimadzi, yofunikira pakuyendetsa kwa rocket. Momwemonso, pazaumoyo, nayitrogeni wamadzimadzi amatengedwa pogwiritsa ntchito ma VIP kusunga zinthu zachilengedwe ndikuthandizira ntchito zamankhwala.

Kutsiliza: Kuchita Bwino kwaVacuum Insulated Pipe

Udindo wavacuum insulated chitoliro mu zoyendera zamadzimadzi za cryogenic sizingachulukitsidwe. Pochepetsa kutentha kwa kutentha kudzera mu njira zapamwamba zotchinjiriza, ma VIP amaonetsetsa kuti madzi a cryogenic akuyenda bwino komanso otetezeka, kuwapangitsa kukhala ofunikira kwa mafakitale omwe amadalira matekinoloje otsika. Pamene kufunikira kwa ntchito za cryogenic kukukula, kufunikira kwavacuum insulated mapaipiidzapitiriza kukwera, kuonetsetsa kuti kutentha ndi chitetezo pa ntchito zofunika kwambiri.
