Kutamiswa kweLN₂: Masisitimu Anodzivirirwa eVacuum eNitrogen yeKuchena Kwakanyanya

Masisitimu ekutamisa nitrogen yemvura anotarisirwa kuita chimwe chinhu chakanaka kwazvo: kuchengetedza LN₂ ichitonhora uye yakagadzikana kubva mutangi rekuchengetera kusvika pakushandiswa. Munzvimbo chaidzo dzemaindasitiri, kunyanya mashandisirwo emagasi e semiconductor ne high-pure, kunyangwe kupisa kudiki kunogona kugadzira utsi, kusagadzikana kwepressure, kana mamiriro ekufamba asingawirirane.

At HL Cryogenics, tinogadzirapombi yekudzivirira mvura inopisauyepombi inochinjikamasisitimu akagadzirirwa kutamiswa kweLN₂ kure nekupisa kushoma. Nekubatanidza kuputira kwevacuum kunochengetwa ne dynamically,mavharuvhu ekudzivirira mhepouyetekinoroji yekuparadzanisa chikamu, masisitimu edu anokwanisa kuchengetedza kutumirwa kwemvura kwechikamu chimwe chete kwakasimba kuburikidza nematanho akaomarara ekuparadzira cryogenic.

Nei Kudzivirira Vacuum Kuchikosha Pakutamiswa kweLN₂

Nitrojeni yemvura inoshanda pa -196 °C. Kana tembiricha yemhepo iri pamusoro pe25 °C, musiyano wetembiricha pamadziro epombi unogona kudarika 200 °C. Pasina kuvharwa kwemhepo kwakanaka, kupisa kunopinda nekukurumidza musystem kuburikidza nekufambisa, kutenderera, uye mwaranzi, zvichigadzira gasi rinobikira uye kuyerera kwezvikamu zviviri kusina kugadzikana.

Yedupombi yekudzivirira mvura inopisaMasisitimu anoshandisa chivakwa chesimbi isina ngura chine madziro maviri chine nzvimbo ine vacuum annular yakawanda inowanzo chengetwa pasi pe 1 × 10⁻⁵ mbar. Pasi pemamiriro aya, gaseous conduction uye convection zvinenge zvava kuda kubviswa. Multilayer insulation (MLI) inoderedzawo kupfuudzwa kwekupisa nekuratidza simba re infrared kubva papombi yemukati inotonhora.

Kana tichienzanisa nekudzivirira furo kwakajairika, simba rekupisa rinoita basa rakaderera zvikuru, zvichiita kuti LN₂ ifambe nemazana emamita uku ichichengetedza mamiriro emvura uye kumanikidzwa kwakasimba.

Sisitimu yeDynamic Vacuum PombiKugadzikana Kwenguva Refu

Chimwe chezvinhu zvinowanzo itika mu cryogenic insulation idambudziko re vacuum zvishoma nezvishoma nekufamba kwenguva. Kubuda kwemweya kubva pamusoro pesimbi isingatsvi, zvinhu zvinodzivirira, uye kuyerera kwegasi kudiki kunowedzera kumanikidzwa kweannulus zvishoma nezvishoma, zvichideredza kushanda kwekupisa.

Kuti tigadzirise izvi,HL CryogenicsinobatanidzaSisitimu yeDynamic Vacuum Pombimu network yekutamisa. Sisitimu iyi inogara ichibvisa nzvimbo ye annular kuti ichengetedze mamiriro e vacuum akasimba panguva yekushanda kwenguva refu.

Module ye vacuum inowanzo sanganisira:

• Pombi dzevacuum dzakaoma kana kuti turbomolecular
• Mageji ekutarisa vacuum
• Zvikamu zvekusveta mamorekuru
• Mavharuvhu ekuparadzanisa uye asingadzore

Nzira iyi yekuchengetedza vacuum inoshanda inoita kuti mashandiro ekudzivirira arambe akafanana mumakore ekushanda uye inonyanya kukosha munzvimbo dze semiconductor uko kugadzikana kwekushisa kweLN₂ kunokanganisa zvakananga kudzokorora kwemaitiro.

Kutumirwa Kwechikamu Chimwe Chete Kwakagadzikana neMavharuvhu Akaputirwa neVacuumuyeZvikamu Zvinoparadzanisa

Mumasisitimu ekutamisa mvura anokonzerwa ne cryogenic, kuchengetedza kuyerera kwemvura muchikamu chimwe chete kwakakosha. Mapoketi emvura ari mukati mepombi anogona kukonzera kuyerera kusina kugadzikana, cavitation, kushanduka-shanduka kwepressure, uye kudzikira kwekuvimbika kwemaitiro.

Yedumavharuvhu ekudzivirira mhepoDzakagadzirwa nemabhoneti akavharirwa ne vacuum-jacket akareba kuti aderedze kupisa kwemunzvimbo yacho kwakatenderedza muviri wevharuvhu. Kurongedza tsinde kunoiswa kunze kwenzvimbo ine cryogenic kudzivirira kuomeswa nechando uye kuve nechokwadi chekuti kushanda kwakavimbika panguva yekutenderera kunodzokororwa.

Pasi perwizi,vacuum insulated phase separatorsBvisa utsi hwakadzika hunobva panguva yekutamiswa. LN₂ inopinda muchikamu chinoparadzanisa zvinhu, zvichiita kuti gasi nezvikamu zvemvura zviparadzane zvakanaka mvura isati yaenderera mberi ichidzika.

Musanganiswa uyu unobatsira kuchengetedza kumanikidzwa kwakasimba uye unoita kuti michina iri pasi pemvura iwane nitrogen yakachena, inotonhorera pasi pemvura.

Kubatanidzwa kweTangi Madiki eNetworks dzeLN₂ dzakaparadzirwa

Kune zvivako zvine mashandisirwo akasiyana-siyana kana nzvimbo dzakawanda dzekushandisa, kuvharidzira pakati kunogona kuvandudza zvakanyanya kugadzikana kwesystem.

YeduMini Tank dzakatevedzana, inobvira pa100 L kusvika 3 000 L, inopa nzvimbo yekuchengetera LN₂ iri pedyo nemidziyo yekugadzira. Tangi rega rega rinoshandisa vacuum insulation uye rutsigiro rwemukati rusina kufambisa simba zvakanyanya kuderedza kuzvimanikidza uye kurasikirwa nekupisa.

Mukushanda kwechokwadi, Mini Tanks dzinobatsira:

• Nzvera kushanduka-shanduka kwekumanikidzwa
• Bata nguva dzekushandiswa zvakanyanya
• Deredza mutoro pahurongwa hukuru hwezvinhu zvinounzwa
• Kuvandudza kugadzikana pedyo nemidziyo inobatwa nenjodzi

Kugadziriswa uku kunoshandiswa zvakanyanya mumakambani ekugadzira ma semiconductor, marabhoritari, uye masisitimu ekugovera gasi remaindasitiri.

Kushanda Kwemasisitimu uye Dhizaini Yeinjiniya

ZvakajairikaHL CryogenicsSisitimu yekufambisa yeLN₂ inoshanda pakati pemabhawa matatu kusvika gumi ine kumhanya kwekuyerera kunosvika 8 m/s.

Kana mamiriro ekushanda akagadzikana, kupisa kwese kunogona kuderedzwa kusvika pa0.25–0.5 W/m zvichienderana nekugadzirwa kwemutsetse. Mumapurojekiti mazhinji, izvi zvinobvumira nitrogen yemvura kufamba mazana emamita nekugadzirwa kweutsi husina kukwana.

Zvikamu zvepaipi zvinochinjika zvinoshandisa 316L stainless steel inner cores pamwe chete nekunze rekusimbisa braids kuti dzisanyanya kumanikidzwa uye dzigare kwenguva refu.

Kushandiswa kweSemiconductor Fab muEast Asia

Kambani inogadzira michina yemagetsi muTaiwan yakavandudza sisitimu yayo yekugovera LN₂ yagara iripo mushure mekusangana nekusagadzikana kweutsi mumapaipi ane insulation yemakanika.

HL Cryogenicsyakapa mhinduro yekuchinjisa yehybrid ine:

• Pombi yekudzivirira mvura inodziyayekoridho huru yekugovera

Batanai naHL Cryogenics

Kutamiswa kweLN₂ kwakavimbika kunoda zvinopfuura kungoisa insulation yakatenderedza pombi. Kugadzikana kwekupisa kwenguva refu kunoenderana nekusimba kwevacuum, kudzora phase, kurongeka kwesystem kwakakodzera, uye mainjiniya akanangana necryogenic.

At HL Cryogenics, tinopa mhinduro dzakakwana dzekushandisa vacuum insulated dzinosanganisira pombi dzevacuum insulated, hose inochinjika, mavharuvhu, maphase separator, uye Mini Tanks dzakagadzirirwa kushanda zvakanaka kwemakumi emakore ekushanda.

Kana uri kuronga network itsva yekugovera LN₂ kana kuvandudza sisitimu iripo ye cryogenic, timu yedu yeinjiniya inogona kupa ongororo yekubuda kwemvura inopisa uye mazano esisitimu akagadzirirwa iwe.
