Sakha iinkqubo zethu zokufaka imibhobho ye-helium engamanzi nge-liquid nitrogen shield ukunciphisa ukuvuza kobushushu ukusuka kubushushu begumbi ukuya kumgca we-helium we-4 K. I-shield ikwi-77 K, isebenza njenge-thermal buffer; ibamba uninzi lobushushu obusebenzisa imisebe kunye nobushushu ngaphambi kokuba ifike kwi-helium. Kwi-HL Cryogenics, le ndlela inyusa ukusebenza kakuhle kwamandla, igcina i-helium ingabili ngokukhawuleza, kwaye inceda imigca emide yokudlulisa isebenze kakuhle nangokuthembekileyo. Uza kufumana i-LN₂ shield ifihliwe ngaphakathi kwethu.Umbhobho ogqunywe nge-vacuumukuseta, kujikelezwe yi-vacuum egcinwe ngononophelo.
Kwinethiwekhi ezinkulu ze-cryogenic, ukutsiba esi sikhuselo esiphakathi asiyondlela ifanelekileyo. Ngaphandle kwaso, ubushushu obuvela kwimitha kunye negesi elahlekileyo ngaphakathi komqobo we-vacuum bungagqitha isekethe ye-helium, nto leyo ebangela ukufuma ngokukhawuleza kwaye kwenze ukusebenza okuzinzileyo kube nzima.
Uyilo lwethu lugxile kwiindlela eziphambili zokudlulisa ubushushu—imitha, ukuqhuba, kunye nokuqhuba igesi eseleyo. I-vacuum iyasusa i-convection, kodwa imitha isatyhala ubushushu kwiindawo ezibandayo. Kulapho i-nitrogen shield ingena khona. Kwi-77 K, ifunxa uninzi lwala mandla, ngoko ke iqhekeza elincinci kuphela elingena kwi-helium. Kwimibhobho ene-vacuum-jacket esebenza kakhulu—ingakumbi kwiinkqubo zokudlulisa ezifuna i-cryogenic—le nitrogen shield ayincedi nje kuphela; yinxalenye ebalulekileyo yobunjineli. Yiyo egcina inkqubo izinzile, isebenza kakuhle, kwaye ingabizi kakhulu ngexesha lonke lokusebenza kwayo.

●Uyilo lwenkqubo kunye nokuhlanganiswa kweemveliso ze-HL Cryogenics
Nangona kunjalo, kwindlela yethu yobunjineli, i-LN2 Shield ngokwayo ayisiyonto izimeleyo kodwa yinkqubo engaphantsi kwenkqubo yonke yepayipi ye-cryogenic. Ngokwesiqhelo, le nkqubo ingaphantsi isetyenziswa kunye ne-Umbhobho ogqunywe nge-vacuum, I-Vacuum Insulated Flexible Hose, kunyeIvalvu Egqunywe Ngomoyaiinkqubo zokwenza inkqubo epheleleyo yokulawula ubushushu. Ngokuxhomekeke kudidi lweprojekthi kunye neemfuno zayo zoxinzelelo, isekethe yekhaka inokulungiswa ngaxeshanye okanye ngokulinganayo.
Kwimeko yokusetyenziswa okuguqukayo okanye ixesha elide,Inkqubo yePompo yeDynamic VacuumIsetyenziselwa ukuqinisekisa uzinzo lwe-vacuum ngaphakathi kwimibhobho. Iya kuqinisekisa ukuba iipropati zokukhusela zombhobho aziyi kuphazamiseka ngenxa yokuvuza okuncinci okanye ukuphuma kwegesi ekuhambeni kwexesha. Ukusetyenziswa kwe-LN2 shielding kunye nokupompa rhoqo kwe-vacuum kusinika ii-coefficients zokudlulisa ubushushu eziphantsi kakhulu.
●Ukusebenza kobushushu kunye nokuziphatha kokuthintela ubushushu nge-vacuum
NgokudibanisaInkqubo yePompo yeDynamic Vacuum, Ivalvu Egqunywe NgomoyakunyeIsahluli seSigaba, sikunika useto oluhambisa i-helium yolwelo ngokufanelekileyo kwaye lugcine iindleko ziphantsi.Itanki encincikunyeIipayipi eziguquguqukayomasijongane nemisebenzi eshukumayo nengaguqukiyo ngokuchanekileyo.
Ngokwembono yobunjineli, ukusebenza kakuhle kwekhaka elisekelwe kwi-nitrogen engamanzi kuxhomekeke kwi-vacuum, ukukhupha ubushushu kwizinto eziphathekayo, kunye noyilo lobushushu oluxhasayo. I-vacuum engaphakathi kwezixhobo zethu ze-HL Cryogenics yenzelwe ukusebenza kuluhlu lwe-10⁻³ - 10⁻⁶ Pa. Kwiingcinezelo ezinjalo, ukuhanjiswa kwegesi kunokungahoywa, kwaye imitha yeyona ndlela iphambili yokudlulisa ubushushu.
Xa usebenzisa umaleko we-nitrogen cooled shield, ukusebenza kakuhle kokudluliselwa kobushushu kuncipha ukuya kuthi ga kwi-70-90% xa kuthelekiswa ne-vacuum insulation enye. Oko kukhokelela ekusebenzeni ngcono kwe-Umbhobho ogqunywe nge-vacuumkunye nokuncipha kokubilisa kwimeko yeenkqubo ze-helium. Kwiindawo ezinkulu zokufakelwa, nokuba kunyuke kancinci ekunciphiseni ukuvuza kobushushu kukhokelela ekongeni okukhulu kwezoqoqosho ngenxa yexabiso eliphezulu le-helium.
Ukukhetha izinto kubalulekile. Sisebenzisa intsimbi engagqwaliyo (eyona idumileyo yi-304L kunye ne-316L), ngenxa yokuqhuba kwayo ubushushu obuphantsi kunye namandla ayo kumaqondo obushushu aphantsi kunye nokukwazi kwayo ukuhlangabezana nemigangatho yokuwelda. Zonke izinto esizifakileyo ziyahlangabezana nemigangatho ye-ASME, CE, kunye ne-ISO yeenqanawa zoxinzelelo kunye nobunjineli be-cryogenic.
●Indima yokuxhasa iinkqubo ezingaphantsi kwe-cryogenic
Ikhaka le-nitrogen aliyi kusebenza kakuhle ngaphandle kweseti yeenkqubo ezingaphantsi kwe-cryogenic. Ngoncedo losapho lwethu lweemveliso ze-HL Cryogenics, esinye sezixhobo esiziyilileyo sibizwa ngokubaIsahluli seSigaba esifakwe iVacuum Insulated.Kubalulekile ukuzinzisa ukuhamba kwezigaba ezibini kunye nokukhuselwa kwi-vapor lock kwimigca yokusasaza.
Ngaphezu koko, uyilo lweIvalvu Egqunywe NgomoyaInjongo yeyokubonelela ngeebhulorho ezishushu ezisezantsi kangangoko ngelixa kugcinwa ukuchaneka kolawulo lokuhamba kwamanzi kwiiyantlukwano zobushushu eziphezulu. Ukusetyenziswa kwezi zixhobo kubaluleke kakhulu kwinkqubo ye-nitrogen engamanzi kunye nemibhobho yenkqubo ye-helium engamanzi enemithwalo eyahlukeneyo.
Esinye isixhobo esihlala sifakelwa kwiinethiwekhi ze-cryogenic ezinomthamo omkhulu yi-Itanki encinciinkqubo. Kunye neyethuInkqubo yePompo yeDynamic Vacuum, zibonelela ngokulinganisela phakathi koxinzelelo, ubushushu, kunye nokusasazwa kwesigaba.
Imeko yesicelo sobunjineli behlabathi lokwenyani
Kwiprojekthi enye ye-LNG eMzantsi-mpuma Asia, kwafuneka sihambise i-helium engamanzi kumgama omde—kwaye ukugcina ilahleko zobushushu ziphantsi kwakubalulekile. Iindlela zokubuyisela i-Helium zazinqongophele, ngoko ke ukulahlekelwa zizixhobo ezingasetyenziswanga kangako kwakuthetha ukuchitha imali. Ukujongana noku, sakhe inkqubo yokukhusela enezigaba ezimbini: sisebenziseUmbhobho ogqunywe nge-vacuumkwaye yongeza isekethe yokukhusela i-nitrogen engamanzi.
Imozulu yaseMzantsi-mpuma Asia ayilungelanga i-cryogenics. Amaqondo obushushu ayedla ngokunyuka abe ngaphezulu kwama-35°C, kwaye umswakama wawunamandla, kodwa inkqubo yahlala kakuhle. Emva kokuba yonke into isebenza, sabona ukwehla okukhulu kwe-helium xa kuthelekiswa noko besikulindele ngaphandle kwe-nitrogen shield.Inkqubo yePompo yeDynamic Vacuumyenze umsebenzi wayo—amanqanaba e-vacuum ahlala eqinile ngexesha lokusebenza okungayekiyo. Nanini na xa sifuna ukwenza ulungiso, iiValve zeVacuum Insulated zaziqinisekisa ukuba siyakwazi ukwahlula iindawo zombhobho ngokukhuselekileyo.
Ukubona amanani, kuyacaca: ukuthintela ubushushu obunezigaba ezininzi akusiyongombono nje kuphela. Kwiindawo ezifana neeterminal ze-LNG kunye nezityalo ze-semiconductor, kubalulekile. Uzinzo lwenkqubo aluyonto esecaleni—luchaza indlela ezi zixhobo ezinokusebenza ngayo ngokufanelekileyo.
Kwi-HL Cryogenics, sakha iinkqubo zokukhusela i-nitrogen engamanzi ezidlala indima ebalulekileyo kubunjineli be-cryogenic banamhlanje—ingakumbi xa kufikwa kwizicwangciso ze-helium ezingamanzi apho ukugcina izinto zizinzile ngokobushushu kubaluleke kakhulu. Sidibanisa i-vacuum insulation ephucukileyo, iindawo ezicwangciswe ngokuchanekileyo, kwaye sinamathela kwimigangatho engqongqo yokuvelisa, ukuze iinkqubo zethu zisebenze ngokuthembekileyo kwiiprojekthi zegesi zoshishino kwihlabathi liphela.
Sisoloko silungisa imibhobho yethu yokukhusela i-vacuum, iipayipi eziguquguqukayo, kwaye sixhasa iinkqubo ezingaphantsi kwe-cryogenic ukujongana nemisebenzi enzima kwizibonelelo ze-LNG, ukuveliswa kwe-semiconductor, kunye neeprojekthi zamandla e-hydrogen kulo lonke elaseYurophu, e-Asia, nakuMbindi Mpuma.
Ukuba ufuna isisombululo esicacileyo esilungiselelwe iprojekthi yakho, okanye ukuba ufuna ukuthetha ngoyilo lwenkqubo, sivulelekile kwiingxoxo zobugcisa kunye neekontraka ze-EPC, iinjineli, kunye namaqela okuthenga.
