Munyika ye cryogenics, kudiwa kwekudzivirira kupisa kunoshanda uye kwakavimbika kwakakosha, kunyanya kana zvasvika pakufambisa zvinwiwa zvinotonhorera zvakanyanya senge liquid helium.Mapaipi ane jekete revacuum(VJP) tekinoroji huru mukuderedza kutamiswa kwekupisa uye kuona kuti mvura dzinopisa dzakadai se liquid helium dzinoramba dziri patembiricha yakaderera inodiwa panguva yekufambisa. Chinyorwa chino chinoongorora basa rakakosha remapaipi ane vacuum jacketed mukushandiswa kwe liquid helium.

Chii chinonzi Vacuum Jacketed Popes?

Mapaipi ane jekete revacuum, inozivikanwawo semapaipi anodzivirirwa, mapaipi ane vacuum insulation layer pakati pemadziro maviri emapaipi akakombama. Iyi vacuum layer inoshanda sechidziviriro chekupisa chinoshanda zvakanyanya, ichidzivirira kutamiswa kwekupisa kuenda kana kubva mukati mepaipi. Kune helium yemvura, iyo inofashaira patembiricha inosvika 4.2 Kelvin (-268.95°C), kuchengetedza tembiricha yakaderera panguva yekufambisa kwakakosha kudzivirira kupwa uye kurasikirwa nezvinhu.

Kukosha kweMapaipi Ane Vacuum Jacketed muLiquid Helium Systems

Helium yemvura inoshandiswa zvakanyanya mumaindasitiri akadai sehutano (yemichina yeMRI), tsvakurudzo yesainzi (muzvishandiso zvinomhanyisa mafambiro ezvimedu), uye kuongorora muchadenga (kwekutonhodza zvikamu zvemuchadenga). Kutakura helium yemvura nepadaro pasina kuwedzera kwakanyanya kwekupisa kwakakosha pakuderedza marara uye kuona kuti maitiro acho anoshanda zvakanaka.Mapaipi ane jekete revacuumdzakagadzirirwa kuchengetedza mvura iri patembiricha yayo inodiwa nekuderedza zvakanyanya kuchinjana kwekupisa.

Kuderedzwa Kuwana Kupisa uye Kurasikirwa Kwekubuda Kwemvura

Chimwe chezvakanakira zvikuru zvemapaipi ane vacuum jacketsMumasystem emvura inonzi liquid helium, kugona kwavo kudzivirira kupisa kupinda. Vacuum layer inopa chipingamupinyi chakakwana kune zvinobva kunze, zvichideredza zvakanyanya mwero wekufashaira kwemvura. Izvi zvakakosha pakuchengetedza mamiriro emvura ehelium panguva yekufambisa munzvimbo refu. Pasina kushandisa vacuum insulation, helium yaizokurumidza kupera, zvichikonzera kurasikirwa nemari uye kusashanda zvakanaka.

Kugara kwenguva refu uye Kuchinjika

Mapaipi ane jekete revacuumZvinoshandiswa mumasisitimu ehelium emvura zvakagadzirwa kuti zvigare kwenguva refu, zvinowanzo gadzirwa nesimbi isingatsvi kana zvimwe zvinhu zvinogona kutsungirira kupisa kwakanyanya uye kushushikana kwemuchina. Mapaipi aya anouyawo mumagadzirirwo anochinjika, zvichibvumira kuiswa nyore mumasisitimu angangoda nzira dzakakombama kana dzakasiyana-siyana. Kuchinjika uku kunoita kuti zvive zvakanaka kune zvivakwa zvakaoma senge marabhoritari, matangi ekuchengetera cryogenic, uye network dzekutakura.

Mhedziso

Mapaipi ane jekete revacuuminoita basa guru mukufambisa helium yemvura, ichipa insulation yekupisa inoshanda zvakanyanya inoderedza kuwedzera kwekupisa uye inoderedza kurasikirwa. Nekuchengetedza kusimba kwemvura inoyerera, mapaipi aya anobatsira kuchengetedza helium inokosha uye kuderedza mari yekushanda. Sezvo maindasitiri achiramba achigadzira zvinhu zvitsva uye achida masisitimu epamusoro emvura inoyerera, basa remapaipi ane vacuum jacketszvichawedzera kukosha. Nekushanda kwavo kwekupisa kusingaenzaniswi uye kugara kwenguva refu,mapaipi ane vacuum jacketsichiri tekinoroji yakakosha mumunda we cryogenics, kunyanya pakushandiswa kwe liquid helium.

Mukupedzisa,mapaipi ane vacuum jackets(VJP) dzinokosha zvikuru mukushandiswa kwehelium yemvura, zvichiita kuti kutakurwa kubudirire, kuderedza marara, uye kuve nechokwadi chekuti masisitimu ekudzivirira kupisa akachengeteka uye akavimbika.
