Chitoliro chotenthetsera cha vacuum(VIP) ndi gawo lofunika kwambiri ponyamula zakumwa zoziziritsa kukhosi, monga gasi wachilengedwe wosungunuka (LNG), haidrojeni yamadzimadzi (LH2), ndi nayitrogeni yamadzimadzi (LN2). Vuto losunga zakumwa izi kutentha kochepa kwambiri popanda kutentha kwakukulu limathetsedwa pogwiritsa ntchito ukadaulo woteteza vacuum. Blog iyi ifotokoza momwe chitoliro chotenthetsera cha vacuumimapereka chitetezo cha kutentha komanso kufunika kwake m'mafakitale omwe amadalira makina a cryogenic.

Kodi ndi chiyaniChitoliro Chotetezedwa ndi Zitsulo?

A chitoliro chotenthetsera cha vacuumIli ndi mapaipi awiri ozungulira: chitoliro chamkati chomwe chimanyamula madzi oundana ndi chitoliro chakunja chomwe chimatseka chitoliro chamkati. Malo pakati pa mapaipi awiriwa amachotsedwa kuti apange vacuum, yomwe imagwira ntchito ngati chotetezera kutentha champhamvu kwambiri. Vacuum imachepetsa kusamutsa kutentha kudzera mu conduction ndi convection, zomwe zimathandiza kusunga madziwo pa kutentha kochepa komwe amafunikira.

Momwe Kuteteza Vacuum Kumagwirira Ntchito

Chinsinsi cha mphamvu ya kutentha yachitoliro chotenthetsera cha vacuum ndi gawo la vacuum. Kusamutsa kutentha kumachitika nthawi zambiri kudzera m'njira zitatu zazikulu: conduction, convection, ndi radiation. Vacuum imachotsa conduction ndi convection chifukwa palibe mamolekyu a mpweya pakati pa mapaipi kuti asamutse kutentha. Kuphatikiza pa vacuum, chitoliro nthawi zambiri chimakhala ndi zotchingira zowunikira mkati mwa vacuum, zomwe zimachepetsa kusamutsa kutentha kudzera mu radiation.

Chifukwa chiyaniChitoliro Chotetezedwa ndi Zitsulo Ndikofunikira pa Machitidwe a Cryogenic

Madzi a cryogenic amakhudzidwa ndi kutentha ngakhale pang'ono, zomwe zingayambitse kupsa, zomwe zimapangitsa kuti zinthu zitayike komanso ngozi zomwe zingachitike.Chitoliro chotenthetsera cha vacuumZimaonetsetsa kuti kutentha kwa madzi oundana monga LNG, LH2, kapena LN2 kumakhalabe kokhazikika panthawi yoyenda. Izi zimachepetsa kwambiri kupangika kwa mpweya woipa (BOG), zomwe zimapangitsa kuti madziwo akhalebe momwe akufunira kwa nthawi yayitali.

Kugwiritsa ntchitoChitoliro Chotetezedwa ndi Zitsulo

Chitoliro chotenthetsera cha vacuumimagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo mphamvu, ndege, ndi zamankhwala. Mu makampani opanga LNG, ma VIP amagwiritsidwa ntchito kusamutsa mpweya wachilengedwe wosungunuka pakati pa matanki osungiramo zinthu ndi malo osungiramo zinthu popanda kutaya kutentha kwambiri. Mu gawo la ndege, ma VIP amatsimikizira kusamutsa bwino kwa haidrojeni yamadzimadzi, komwe ndikofunikira kwambiri pakuyendetsa ma roketi. Mofananamo, pazaumoyo, nayitrogeni yamadzimadzi imanyamulidwa pogwiritsa ntchito ma VIP kuti asunge zinthu zachilengedwe ndikuthandizira ntchito zachipatala.

Kutsiliza: Kugwira Ntchito Bwino kwaChitoliro Chotetezedwa ndi Zitsulo

Udindo wachitoliro chotenthetsera cha vacuum Mu kayendedwe ka madzi a cryogenic sikunganyalanyazidwe kwambiri. Mwa kuchepetsa kusamutsa kutentha kudzera mu njira zamakono zotetezera kutentha, ma VIP amatsimikizira kunyamula bwino komanso kotetezeka kwa madzi a cryogenic, zomwe zimapangitsa kuti akhale ofunikira m'mafakitale omwe amadalira ukadaulo wotsika kutentha. Pamene kufunikira kwa kugwiritsa ntchito cryogenic kukukula, kufunika kwamapaipi otetezedwa ndi vacuumidzapitirira kukwera, kuonetsetsa kuti kutentha kukugwira ntchito bwino komanso kutetezeka pa ntchito zofunika kwambiri.
