Vacuum insulated pombi(VIP) chinhu chakakosha pakutakura zvinwiwa zve cryogenic, senge liquefied natural gas (LNG), liquid hydrogen (LH2), uye liquid nitrogen (LN2). Dambudziko rekuchengeta zvinwiwa izvi patembiricha yakadzika kwazvo pasina kuchinjisa kupisa kunogadziriswa uchishandisa vacuum insulation tekinoroji. Iyi blog inotsanangura sei vacuum insulated pombiinopa kupisa kwemafuta uye kukosha kwayo mumaindasitiri anovimba ne cryogenic system.

Chii chinonzi aVacuum Insulated Pipe?

A vacuum insulated pombiine mapaipi maviri akadzikama: pombi yemukati inotakura cryogenic fluid uye pombi yekunze inovhara pombi yemukati. Nzvimbo iri pakati pemapombi maviri aya inobviswa kuti igadzire vacuum, iyo inoshanda seyakanyanya kushanda kwazvo thermal insulator. Iyo vacuum inoderedza kupisa kwekufambisa kuburikidza ne conduction uye convection, iyo inobatsira kuchengetedza mvura painoda tembiricha yakaderera.

Mashandiro Anoita Vacuum Insulation

Chinokosha chekushanda kwekupisa kweavacuum insulated pombi ndiyo vacuum layer. Kuchinjisa kupisa kunowanzoitika kuburikidza nematanho matatu makuru: conduction, convection, uye radiation. Iyo vacuum inobvisa conduction uye convection nekuti hapana mamorekuru emhepo munzvimbo iri pakati pepombi kuendesa kupisa. Kuwedzera kune vacuum, pombi inowanzobatanidza inovhenekera kudzivirirwa mukati mevacuum nzvimbo, ichideredza kupisa kwekushisa kuburikidza nemwaranzi.

SeiVacuum Insulated Pipe Yakakosha kune Cryogenic Systems

Cryogenic zvinwiwa zvinonzwa kunyange kudiki kuwedzera kwekushisa, izvo zvinogona kuita kuti zvinyunguduke, zvichitungamira mukurasikirwa kwechigadzirwa uye njodzi dzinogona kuitika.Vacuum insulated pombiinovimbisa kuti tembiricha ye cryogenic fluid seLNG, LH2, kana LN2 inoramba yakagadzikana panguva yekufambisa. Izvi zvinoderedza zvakanyanya boil-off gasi (BOG) kuumbwa, kuchengetedza mvura iri munzvimbo yainoda kwenguva yakareba.

Zvikumbiro zveVacuum Insulated Pipe

Vacuum insulated pombiinoshandiswa mumaindasitiri akasiyana siyana, anosanganisira simba, aerospace, uye minda yekurapa. Muindasitiri yeLNG, maVIP anoshandirwa kuendesa liquefied gasi rechisikigo pakati pematangi ekuchengetera uye zviteshi zvine kurasikirwa kushoma kwemafuta. Muchikamu chemuchadenga, maVIP anove nechokwadi chekufambisa kwakachengeteka kwemvura yehydrogen, yakakosha pakufambisa kweroketi. Saizvozvo, muhutano, mvura nitrogen inotakurwa ichishandisa VIP kuchengetedza biological zvinhu uye kutsigira kurapwa.

Mhedziso: Kubudirira kweVacuum Insulated Pipe

Basa revacuum insulated pombi mu cryogenic liquid transportation haigoni kupfuudzwa. Nekudzikisira kutamisa kupisa kuburikidza nemhando dzepamusoro dzekudzivirira, maVIP anovimbisa kutakura kwakachengeteka uye kwakanaka kwecryogenic zvinwiwa, zvichiita kuti zvive zvakakosha kumaindasitiri anoenderana neakadzika tekinoroji. Sezvo kudiwa kwe cryogenic application kuchikura, kukosha kwevacuum insulated pombiicharamba ichikwira, kuve nechokwadi chekushanda kwekushisa uye kuchengeteka mumabasa anokosha.
