Ukudluliselwa kwe-LN₂: Izinhlelo Zokufaka Umshini Ongangenisi Umswakama Ze-Nitrogen Ehlanzekile Kakhulu

Izinhlelo zokudlulisa i-nitrogen ewuketshezi kulindeleke ukuthi zenze into eyodwa kahle kakhulu: ukugcina i-LN₂ ibanda futhi izinzile kusukela ethangini lokugcina kuya endaweni yokusetshenziswa. Ezindaweni zangempela zezimboni, ikakhulukazi ukusetshenziswa kwegesi ye-semiconductor kanye ne-high-purity gas, ngisho nokungena okuncane kokushisa kungadala ukwakheka komhwamuko, ukungazinzi kwengcindezi, noma izimo zokugeleza ezingaguquki.

At I-HL Cryogenics, siyaklamaipayipi elivalekile elinokushisafuthiipayipi eliguquguqukayoizinhlelo eziqondene ngqo nokudluliselwa kwe-LN₂ ebangeni elide ngokulahlekelwa okuncane kokushisa. Ngokuhlanganisa ukuvikela i-vacuum okugcinwe ngokuguquguqukayo,amavalvu afakwe ugesi, futhiubuchwepheshe bokuhlukaniswa kwesigaba, izinhlelo zethu ziyakwazi ukugcina ukulethwa koketshezi kwesigaba esisodwa okuzinzile kumanethiwekhi okusabalalisa e-cryogenic ayinkimbinkimbi.

Kungani Ukufakwa Kwe-Vacuum Kubalulekile Ekudlulisweni Kwe-LN₂

I-nitrogen ewuketshezi isebenza cishe ku--196 °C. Njengoba amazinga okushisa avame ukuba ngaphezu kuka-25 °C, umehluko wokushisa odongeni lwepayipi ungadlula u-200 °C. Ngaphandle kokuvikela okusebenzayo, ukushisa kungena ngokushesha ohlelweni ngokusebenzisa ukuqhutshwa komoya, ukujikeleza komoya, kanye nemisebe, okukhiqiza igesi yokubilisa kanye nokugeleza kwezigaba ezimbili okungazinzile.

Okwethuipayipi elivalekile elinokushisaIzinhlelo zisebenzisa isakhiwo sensimbi engagqwali esinezindonga ezimbili esinesikhala esiphezulu se-vacuum annular esivame ukugcinwa ngaphansi kwe-1 × 10⁻⁵ mbar. Ngaphansi kwalesi simo, ukuqhutshwa kwegesi kanye ne-convection cishe kuqedwa. Ukufakwa kwe-Multilayer insulation (MLI) kunciphisa kakhulu ukudluliswa kokushisa okubangelwa imisebe ngokukhombisa amandla e-infrared kude nepayipi langaphakathi elibandayo.

Uma kuqhathaniswa nokufakwa kwe-foam okuvamile, ukuhanjiswa kokushisa okusebenzayo kuphansi kakhulu, okuvumela i-LN₂ ukuthi idluliselwe ngaphezu kwamamitha angamakhulu ngenkathi igcina isimo soketshezi kanye nengcindezi ezinzile.

Uhlelo Lwephampu Yokupompa I-DynamicUkuqina Kwesikhathi Eside

Enye yezinkinga ezivamile ekufakweni kwe-cryogenic ukuwohloka kancane kancane kwe-vacuum ngokuhamba kwesikhathi. Ukukhishwa kwegesi okusele ezindaweni zensimbi engagqwali, izinto zokufaka ukushisa, kanye nokugeleza kwegesi okuncane kukhulisa kancane kancane ingcindezi ye-annulus, kunciphisa ukusebenza kokushisa.

Ukuze kuxazululwe lokhu,I-HL CryogenicsihlanganisaUhlelo Lwephampu Yokupompa I-Dynamickunethiwekhi yokudlulisa. Uhlelo lukhipha njalo noma ngezikhathi ezithile isikhala se-annular ukuze kugcinwe izimo ze-vacuum ezizinzile phakathi nokusebenza kwesikhathi eside.

Imodyuli ye-vacuum ivame ukufaka:

• Amaphampu e-vacuum e-dry scroll noma e-turbomolecular
• Amageyiji okuqapha i-vacuum
• Amayunithi okufaka i-molecular sieve adsorption
• Amavalvu okuhlukaniswa kanye nokungabuyisi

Le ndlela yokulungisa i-vacuum esebenzayo igcina ukusebenza kokushisa kuhambisana phakathi neminyaka yokusebenza futhi ibaluleke kakhulu ezindaweni ze-semiconductor lapho ukuzinza kokushisa kwe-LN₂ kuthinta ngqo ukuphindaphindwa kwenqubo.

Ukulethwa Okuzinzile Kwesigaba Esisodwa ngeAmavalvu Afakwe Umshini WokufudumezafuthiIzihlukanisi Zesigaba

Ezinhlelweni zokudlulisa i-cryogenic, ukugcina ukugeleza koketshezi lwesigaba esisodwa kubalulekile. Amaphakethe omhwamuko ngaphakathi kwepayipi angaholela ekugelezeni okungazinzile, ukugoba, ukuguquguquka kwengcindezi, kanye nokwehliswa kokuthembeka kwenqubo.

Okwethuamavalvu afakwe ugesizenzelwe ama-bonnet anwetshiwe anejakethi ye-vacuum ukuze kuncishiswe ukungena kokushisa kwendawo emzimbeni we-valve. Ukufakwa kwesiqu kubekwa ngaphandle kwendawo ekhanyayo ukuze kuvinjelwe ukubanda nokuqinisekisa ukusebenza okuthembekile ngesikhathi sokujikeleza okuphindaphindiwe.

Ngaphansi komfula,abahlukanisi besigaba esifakwe i-vacuumsusa umusi oqukethwe ngesikhathi sokudlulisa. I-LN₂ ingena esihlukanisini ngendlela eqondile, ivumela izigaba zegesi noketshezi ukuthi zihlukane kahle ngaphambi kokuba uketshezi luqhubeke phansi.

Le nhlanganisela isiza ukugcina ingcindezi izinzile futhi iqinisekisa ukuthi imishini esezansi komfula ithola i-nitrogen ewuketshezi ehlanzekile, epholile ngaphansi.

Ukuhlanganiswa Kwethangi Elincane Kwamanethiwekhi E-LN₂ Asatshalaliswa

Ezikhungweni ezinezidingo ezishintshashintshayo noma iziteshi eziningi zokusebenzisa, ukubhafa okuphakathi kungathuthukisa kakhulu ukuzinza kwesistimu.

OkwethuUchungechunge lwethangi elincane, kusukela ku-100 L kuya ku-3 000 L, inikeza isitoreji sendawo se-LN₂ eduze kwemishini yokucubungula. Ithangi ngalinye lisebenzisa ukuvikela i-vacuum kanye nezisekelo zangaphakathi ezisebenzisa ugesi ophansi ukuze kuncishiswe ukuzicindezela kanye nokulahlekelwa ukushisa.

Ekusebenzeni okungokoqobo, ama-Mini Tanks asiza:

• Munca ukuguquguquka kwengcindezi
• Phatha izikhathi zokusetshenziswa okuphezulu
• Nciphisa umthwalo ohlelweni oluyinhloko lokuphakelwa
• Thuthukisa ukuzinza eduze kwemishini ebucayi

Lokhu kulungiselelwa kusetshenziswa kabanzi kumafektri e-semiconductor, amalabhorethri, kanye nezinhlelo zokusabalalisa igesi yezimboni.

Ukusebenza Kwesistimu Nokuklama Ubunjiniyela

OkujwayelekileI-HL CryogenicsUhlelo lokudlulisa i-LN₂ lusebenza phakathi kwamabha angu-3 no-10 ngesivinini sokugeleza esifinyelela ku-8 m/s.

Kuqinileipayipi elivalekile elinokushisangokuvamile isetshenziselwa ukugijima okuqondile okude, kuyilaphoi-vacuum efudumele eguquguqukayoIzingxenye zamapayipi zifakwa ezindaweni zokuxhuma imishini, amajoyinti okunweba, noma izindawo ezidinga isinxephezelo sokunyakaza.

Ngaphansi kwezimo zokusebenza ezizinzile, ukuvuza kokushisa okuphelele kungancishiswa kube cishe ngu-0.25–0.5 W/m kuye ngokucushwa komugqa. Emaphrojekthini amaningi, lokhu kuvumela i-nitrogen ewuketshezi ukuthi ihambe amamitha angamakhulu amaningana ngokukhiqizwa komhwamuko ophansi.

Izingxenye zepayipi eziguquguqukayo zisebenzisa ama-core angaphakathi ensimbi engagqwali angu-316L ahlanganiswe nama-braids angaphandle okuqinisa ukumelana nengcindezi nokuphila isikhathi eside.

Isicelo se-Semiconductor Fab eMpumalanga Asia

Umkhiqizi we-semiconductor eTaiwan uthuthukise uhlelo lwakhe lokusabalalisa lwe-LN₂ olukhona ngemuva kokubhekana nokungazinzi komhwamuko emapayipini afakwe ugesi ngomshini.

I-HL Cryogenicsinikeze ikhambi lokudlulisa elihlanganisiwe eliqukethe:

• Ipayipi elivalekile elinomshini wokuhlanzayendlela enkulu yokusabalalisa
• Ipayipi eliguquguqukayo elivalekile elinomoyaezindaweni zokuxhumanisa amathuluzi
• I-Centralizedukupompa kwe-vacuum okunamandla
• Izihlukanisi zesigaba ezifakwe ugesiendaweni ngayinye yokukhiqiza

Ngemva kokufakwa, ukuvuza kokushisa kwesistimu okulinganisiwe kwaqina cishe ku-0.27 W/m, futhi indawo yasusa ukuphazamiseka kokukhiqiza okuhlobene ne-LN₂ ngesikhathi sokusebenza okuqhubekayo.

Ukuthobela Imithetho kanye Nezicelo Zomhlaba Wonke

I-HL Cryogenicsizinhlelo zakhiwe ngokuhambisana nezindinganiso ezinkulu zomhlaba wonke ze-cryogenic, okuhlanganisa:

Izimiso ezifanayo zokuvimbela i-vacuum ezisetshenziswa ku-LN₂ zingashintshwa futhi ukuze zisetshenziswe ku-oxygen ewuketshezi, i-argon ewuketshezi, i-LNG, kanye ne-hydrogen ewuketshezi.

Hlanganyela noI-HL Cryogenics

Ukudluliselwa kwe-LN₂ okuthembekile kudinga okungaphezu nje kokwengeza ukufudumala okuzungeze ipayipi. Ukuqina kokushisa kwesikhathi eside kuncike ekuqineni kwe-vacuum, ukulawulwa kwesigaba, ukwakheka kwesistimu efanele, kanye nobunjiniyela obuqondene ne-cryogenic.

At I-HL Cryogenics, sinikeza izixazululo zokudlulisa ezigcwele ezifakwe i-vacuum insulation okuhlanganisa ipayipi elifakwe i-vacuum insulation, ipayipi eliguquguqukayo, ama-valve, abahlukanisi besigaba, kanye nama-Mini Tanks aklanyelwe ukusebenza okuzinzile kwe-cryogenic eminyakeni eminingi yokusebenza.

Uma uhlela inethiwekhi entsha yokusabalalisa i-LN₂ noma uthuthukisa uhlelo olukhona lwe-cryogenic, ithimba lethu lobunjiniyela lingakunikeza ukuhlaziywa kokuvuza kokushisa kanye nezincomo zesistimu ezenziwe ngokwezifiso ezenzelwe uhlelo lwakho lokusebenza.
