Ingcindezi efanele yomklamo wemigqa yokudlulisa i-nitrogen ewuketshezi ivame ukuba phakathi kwe-PN16 ne-PN40 (cishe i-1.6 kuya ku-4.0 MPa), kodwa lokhu kungashintsha ngokusekelwe ekusethweni kwesistimu, izimo lapho isebenza khona, kanye nemingcele yokuphepha. Ukuqinisekisa ukuphepha nokuthembeka kwesikhathi eside, sikhetha ingcindezi yomklamo ephakeme ngokuphindwe ka-1.5 kuya ku-2 kunengcindezi yokusebenza ephezulu yokusetshenziswa kwezimboni eziningi, njengoba kudingeka yi-ASME B31.3 noma i-EN 13480.
Kubunjiniyela be-cryogenic, ukuthola ingcindezi efanele yokuklama akuyona nje indaba yokulandela imithetho; kuthinta nokuphepha, ukusebenza kokushisa, kanye nezindleko zomjikelezo wokuphila kohlelo. Sicabanga ngengcindezi yokuklama kwa-HL Cryogenics njengesinqumo esicabangela izici eziningi ezahlukene, njengezakhiwo zoketshezi, izinguquko zokucindezela, kanye nendlela uhlelo oluzosetshenziswa ngayo.
Izinhlelo ze-nitrogen eziwuketshezi zivame ukusebenza ngokucindezela okuphansi kuya kokuphakathi (0.2–1.6 MPa). Kodwa-ke, izimo zesikhashana njengokuqala kwephampu, ukuvalwa kwevalvu, noma imicimbi yokuhwamuka kungadala ukuphakama kokucindezela. Yingakho singalokothi siklame ngokusekelwe kuphela kungcindezi yokusebenza evamile; kunalokho, sifaka ukuziphatha kwesistimu eguquguqukayo ekubaleni kwethu.
Okuqukethwe
1. Izici Eziyinhloko Ezithonya Ingcindezi Yomklamo
2. Ububanzi Bokucindezela Okuvamile Komklamo
3. Izingxenye Zesistimu Ezithonya Umklamo Wokucindezela
4. Izicelo Kuzo Zonke Izimboni Nezifunda
●Izici Eziyinhloko Ezithonya Ingcindezi Yomklamo
1. Izikhathi Ezifushane Nengcindezi Yokusebenza
Isisekelo yingcindezi ephezulu kakhulu okulindeleke ukuthi isetshenziswe. Kodwa futhi sidinga ukucabanga ngalokhu:
Ukucindezela ekukhishweni kwephampu
Ngesikhathi sokusebenza kwe-valve okusheshayo, ingcindezi iyakhuphuka.
Ukwanda kokushisa ezindaweni ezivaliwe
Kuhlelo lokudlulisa i-cryogenic oluklanywe kahle, lezi zinto zingakhuphula ingcindezi yangaphakathi ngo-30% kuya ku-50% ngaphezu kwezimo ezizinzile.
2. Ukulawula Ukuvuza Kokushisa kanye Nokushiswa Komshini Wokushayisa
A Ipayipi Elifakwe Umshini Wokuhlanzakuvimbela ukushisa ukuthi kungangeni, okunciphisa ukubila kwe-nitrogen. Kodwa ngisho nokuvuza okuncane kokushisa kungabangela ukuhwamuka kwendawo, okuphakamisa ingcindezi ngaphakathi kohlelo.
Yingakho ukusebenza kwe-vacuum insulation kuhlobene ngqo nokuqina kwengcindezi. Izinhlelo zethu kwa-HL Cryogenics zenzelwe ukugcina ukuvuza kokushisa kuncane, okugcina izinguquko zengcindezi zingaphakathi kwamazinga angabikezelwa.
3. Ukukhethwa Kwezinto Nobuqotho Besakhiwo
Ukukhethwa kwezinsimbi ezingagqwali njenge-SS304 noma i-SS316 kubalulekile kakhuluipayipi le-cryogenicizinhlelo. Lezi zinto zigcina amandla omshini emazingeni okushisa aphansi futhi zihambisana nezindinganiso ze-ASME kanye ne-EN.
Ingcindezi yomklamo kumele ivumelane nalokhu:
- Amanani okucindezeleka avumelekile emazingeni okushisa acwebezelayo
- Ukubalwa kobukhulu bodonga ngekhodi ngayinye
- Ukumelana nokukhathala isikhathi eside
●Ububanzi Bokucindezela Okuvamile Komklamo kanye Nendima Yobuchwepheshe Be-Vacuum Ekuqineni Kokucindezela
NgokuhlanganisaUhlelo Lwephampu Yokupompa I-Dynamic, I-Vacuum Insulated Valve, futhiIsihlukanisi Sesigaba, sikunikeza isethaphu esihambisa i-helium ewuketshezi kahle futhi sigcine izindleko ziphansi.Ithangi ElincanekanyeAmapayipi Aguquguqukayoake siphathe imisebenzi yeselula kanye neyodwa ngokunemba.
Kusukela emsebenzini wethu kumaphrojekthi egesi yezimboni, sivame ukusikisela:
I-PN16–PN25 yezinhlelo ezincane (ukunikezwa kweTanki Elincane)
Ukusatshalaliswa okujwayelekile kwezimboni: PN25 kuya ku-PN40
Ama-PN40 nangaphezulu enzelwe izinhlelo ezisebenza kahle kakhulu noma ezikude.
A Ipayipi Eliguquguqukayo Elifakwe Umshini Wokufudumezaivame ukukalwa ngendlela efanayo nokuxhumeka okuguquguqukayo, kodwa futhi kufanele ikwazi ukubhekana nokucindezeleka komshini kanye nokunyakaza, okungashintsha imingcele yokuphepha.
Ukuhlanganiswa kwe-Uhlelo Lwephampu Yokupompa I-Dynamicumehluko omkhulu phakathi kwezinhlelo zesimanje. Lobu buchwepheshe bugcina izinga le-vacuum esikhaleni sepayipi noma ipayipi eliyi-cryogenic ezingeni elithile.
Ngaphandle kokulungiswa njalo kwe-vacuum, ukusebenza kwe-insulation kuya ngokuya kuba kubi ngokuhamba kwesikhathi ngenxa ye-
Ukukhipha igesi
Ukuvuza okuncane
Ukugcwala kwamanzi
OkwethuUhlelo Lwephampu Yokupompa I-Dynamickuqinisekisa:
- Amazinga e-vacuum azinzile eminyakeni yokusebenza
- Ukusebenza okushisayo okuhambisanayo
- Ingozi encishisiwe yokwanda kwengcindezi ngenxa yokungena kokushisa
Lokhu kunegalelo ngqo ekwehliseni izidingo zokucindezela komklamo kanye nokuthuthukiswa kwemingcele yokuphepha.
●Izingxenye Zesistimu Ezithonya Umklamo Wokucindezela
Ivalvu ene-Vacuum Insulation
A I-Vacuum Insulated ValveKubaluleke kakhulu ekulawuleni ukugeleza kwamanzi nokuvimbela ukushisa ukuthi kungaphumi. Ukwakheka kwama-valve angalungile kungenza amabhuloho okushisa, okungabangela ukuhwamuka kwendawo kanye nokunyuka kwengcindezi.
Siklama ama-valve ukuze:
Gcina i-vacuum iqhubeka
Ukulahlekelwa ukushisa okuphansi
Qiniseka ukuthi ukulawula ukugeleza kusebenza kahle ngaphandle kokubangela ukushaqeka kwengcindezi.
Isihlukanisi Sesigabange-Vacuum Insulation
Ukugeleza kwezigaba ezimbili kuyinkinga enkulu kunoma yiluphi uhlelo lwe-nitrogen oluwuketshezi. Isihlukanisi sesigaba esifakwe i-vacuum siqinisekisa ukuthi uketshezi kuphela olufika kumsebenzisi wokugcina nokuthi umhwamuko ugcinwa uhlukile ngokuphephile.
Lokhu kuyayeka:
Ukugeleza okungazinzile Izinguquko zokucindezela Izilinganiso ezinganembile
Ngokugcina isigaba sizinzile, sigcina ingcindezi kanye nokusebenza kwesistimu kuzinzile.
●Isimo Sobunjiniyela Sangempela
SisebenziseIpayipi Elifakwe Umshini Wokuhlanzaubuchwepheshe bokuklama uhlelo lokudlulisa i-nitrogen oluwuketshezi oluthatha amamitha angaphezu kwama-500 lwephrojekthi yesakhiwo se-semiconductor muva nje eMpumalanga Asia.
Imininingwane yokuqala evela kuklayenti ithi ingcindezi yomklamo kufanele ibe yi-PN16. Kodwa ngemva kokubheka:
Izici zephampu
Ukujikeleza okusheshayo kwevalvu
Ubude bepayipi
Siphakamise ukuthi uthuthukele ku-PN25. Lolu shintsho luyekise ukukhuphuka kwengcindezi okungenzeka ngesikhathi sokusebenza okuphezulu futhi lwaqinisekisa ukuthi inkampani ilandela amazinga e-ISO kanye ne-SEMI.
Umphumela waba:
Akukho ukwehluleka ngenxa yengcindezi
Izinqubo ezizinzile kakhulu
Ukusetshenziswa okuncane kwe-nitrogen ngenxa yokuvikela okungcono
●Imibuzo Evame Ukubuzwa
Kusukela ngo-1992, i-HL Cryogenics ibilokhu igxile ekuklameni nasekukhiqizeni izinhlelo zamapayipi e-cryogenic afakwe i-vacuum ephezulu kanye nemishini yokusekela ehlobene, eyenzelwe ukuhlangabezana nezidingo zamakhasimende ezahlukahlukene. Sinezitifiketi ze-ASME, CE, kanye ne-ISO 9001, futhi sinikeze imikhiqizo nezinsizakalo emabhizinisini amaningi aziwayo emhlabeni jikelele. Ithimba lethu liqotho, linomthwalo wemfanelo, futhi lizibophezele ekwenzeni kahle kuyo yonke iphrojekthi esiyenzayo.

Eminye imishini yokusekela ye-cryogenic ehlobene namapayipi e-VI — kufaka phakathi kodwa kungagcini ngamaqembu ama-valve okusiza ukuphepha, ama-gauge wezinga loketshezi, ama-thermometer, ama-pressure gauge, ama-vacuum gauge, namabhokisi okulawula kagesi.
Siyajabula ukwamukela ama-oda anoma yiluphi usayizi — kusukela kumayunithi angawodwa kuya kumaphrojekthi amakhulu.
Ipayipi Elifakwe I-Vacuum Insulated le-HL Cryogenics (VIP) lenziwa ngokuhambisana neKhodi Yepayipi Lokucindezela le-ASME B31.3 njengendinganiso yethu.
I-HL Cryogenics ingumkhiqizi wemishini ekhethekile yokuhlanza, ethola zonke izinto zokusetshenziswa ezivela kubaphakeli abafanelekayo kuphela. Singathola izinto ezihlangabezana namazinga nezimfuneko ezithile njengoba kuceliwe amakhasimende. Ukukhetha kwethu izinto ezivamile kufaka phakathi i-ASTM/ASME 300 Stainless Steel enokwelashwa kwendawo efana nokuhlanza nge-acid, ukupholisha ngomshini, ukupholisha okukhanyayo, kanye nokupholisha nge-electro.
Usayizi kanye nomfutho womklamo wepayipi langaphakathi kunqunywa ngokwezidingo zekhasimende. Usayizi wepayipi langaphandle ulandela izincazelo ezijwayelekile ze-HL Cryogenics, ngaphandle uma kuchazwe ngenye indlela yikhasimende.
Uma kuqhathaniswa nokufakwa kwamapayipi okuvamile, uhlelo lwe-vacuum oluqinile luhlinzeka ngokufakwa kokushisa okuphezulu, okunciphisa ukulahlekelwa kwegesi kumakhasimende. Luphinde lube ngcono kakhulu kunesistimu ye-VI enamandla, okunciphisa ukutshalwa kwezimali kokuqala okudingekayo kumaphrojekthi.
