Sivavanya amandla obunjineli, ukusebenza kwe-vacuum insulation kunye nokuzinza kwenkqubo ixesha elide phantsi kweemeko zokusebenza ze-EPC ukuze sikhethe umthengisi wezixhobo ze-cryogenic onokuthenjwa. "Ngokwenyani, sikhetha ababoneleli abanokubonelela ngeenkqubo zokudlulisa i-cryogenic ezipheleleyo, ezidibeneyo, kungekuphela nje kwezinto, kunye nokusebenza okuqinisekisiweyo kokusetyenziswa kwegesi yemizi-mveliso, i-LNG kunye ne-semiconductor," utshilo.
Kwiiprojekthi ze-EPC, ukukhethwa kwababoneleli sisigqibo sobunjineli benkqubo hayi uthelekiso lokuthengwa. Umthengisi onobuchule bobuchwephesha kufuneka abonise ukuba ulawula ukunciphisa ukuvuza kobushushu, uzinzo lwe-vacuum, ukuthembeka koomatshini kunye nokuthembeka komjikelo wobomi kuzo zonke iindawo ezisebenzisanayo ze-cryogenic.
Isiqinisekiso somthengisi yingxaki yobunjineli kwinqanaba lenkqubo kwi-HL Cryogenics. Sijonga umsebenzi wenxalenye nganye yesiseko esipheleleyo se-cryogenic, kungekhona njengeenxalenye ezahlukeneyo.
Umda ophambili wokusebenza kwayo nayiphi na inkqubo yokudlulisa i-cryogenic kukungena kobushushu. Ubungakanani obuncinci bokuvuza kobushushu bubangela ilahleko ezigqithisileyo zokufuma, ukuguquguquka koxinzelelo kunye nokusebenza kakuhle kwenkqubo.
Yiyo loo nto senza abavelisi kwaye senza ubunjineliUmbhobho ogqunywe nge-vacuum, Umbhobho oguquguqukayo ogqunywe nge-vacuumkunyeIvalvu Egqunywe Ngomoyaiindibano ezinolawulo olungqongqo lomgangatho we-vacuum annular, uxinano lwe-insulation oluneziteya ezininzi, kunye nokunciphisa i-thermal bridging yentsimbi engatyiwayo.
Inkqubo yemibhobho ye-cryogenic, eyilwe ngokufanelekileyo, inokunciphisa ukuvuza kobushushu ngaphezulu kwama-80-90% xa kuthelekiswa nemibhobho eqhelekileyo egqunyiweyo. Iphucula ngokuthe ngqo uzinzo lweenkqubo ze-nitrogen engamanzi, ukusebenza kakuhle kokudluliselwa kwe-LNG kunye nokuchaneka kokuhanjiswa kwegesi kwimizi-mveliso.
Amaqela ethu obunjineli alinganisa ukuhanjiswa kobushushu, amazinga okubola kwe-vacuum kunye nokuziphatha kokuqina kwezinto zokusebenza ukusuka kwi--196°C (i-nitrogen engamanzi) ukuya kwi--253°C (i-hydrogen engamanzi).

●Ikhrayitheriya yoKhetho oluPhambili 1: Uzinzo lweNkqubo yoVuthamo ngokuhamba kwexesha
Umbuzo omkhulu ngababoneleli ulula: ngaba i-vacuum iyaqhubeka izinzile emva kokuqalisa, okanye akunjalo?
Sixhomekeke kwiInkqubo yePompo yeDynamic Vacuumukugcina i-vacuum iqinile kwiindawo ezinkulu ezicwangcisiweyo. Iinkqubo ezizinzileyo zihlala apho, kodwa ukupompa okunamandla kuyaqhubeka nokusebenza—ukulandela ukuvuza okuncinci, ukusingatha ukuphuma kwegesi, kunye nokujongana nalo lonke uxinzelelo oluvela kwimijikelo yobushushu.
Ngale ndlela, sigcina amanqanaba e-vacuum engaphantsi kwe-10⁻³ mbar apho kubaluleke khona kakhulu. Ufumana ukuvuza okuncinci kobushushu, nokuba kusemva kweminyaka. Ukongeza, ukuthembeka kwemisebenzi ye-LNG eqhubekayo kunye neenethiwekhi ezinkulu zegesi kuyakhula ngokwenene.
Kwiiprojekthi ze-EPC, oku kuthetha ukuba ukugcinwa kweenkonzo kuncinci. Ekuhambeni kwexesha, yonke imisebenzi ihamba kakuhle kwaye ibiza kancinci.
●Ikhrayitheriya yoKhetho oluPhambili 2: Ukuhlanganiswa kweCandelo leNqanaba leNkqubo
NgokudibanisaInkqubo yePompo yeDynamic Vacuum, Ivalvu Egqunywe NgomoyakunyeIsahluli seSigaba, sikunika useto oluhambisa i-helium yolwelo ngokufanelekileyo kwaye lugcine iindleko ziphantsi.Itanki encincikunyeIipayipi eziguquguqukayomasisebenze imisebenzi eshukumayo nengaguqukiyo ngokuchanekileyo.
Iinkqubo ze-Cryogenic zisebenza kakuhle njengenethiwekhi edibeneyo, kungekhona iqela lamalungu azenzela izinto zawo.
SidibanisaUmbhobho ogqunywe nge-vacuum, Umbhobho oguquguqukayokunyeIvalvu Egqunywe Ngomoyakwiseti enye edibeneyo egcina uxinzelelo luzinzile kwaye ilawula utshintsho lwesigaba.
Umbhobho oguquguqukayo udlala indima ebalulekileyo xa izixhobo zihamba okanye zishukuma kwaye amaqondo obushushu etshintsha-tshintsha — kunzima ngokwaneleyo ukuhlala uguquguqukayo ngelixa ubambe i-vacuum yayo, nangona emva kwemijikelo emininzi eshushu nebandayo.
Kwiindawo zolawulo ezibalulekileyo, iVacuum InsulatedIsahluli seSigabaigcina ulwelo nomphunga zahlulwe. Ngale ndlela, izixhobo ezisezantsi ezifana nee-vaporizer ze-LNG okanye iinkqubo zokupholisa ze-semiconductor ziphepha ukuhamba okungcolileyo kwezigaba ezibini kwaye zihlala zizinzile.
●Ikhrayitheriya yoKhetho oluPhambili 3: Ulawulo loBunjineli bokuziphatha kweSigaba
Ukungazinzi kwesigaba yingxaki enkulu kubunjineli be-cryogenic, ingakumbi xa kuziwa kwimisebenzi ye-EPC.
Kulapho keIsahluli seSigaba esifakwe i-Vacuumingena ngaphakathi. Esi sixhobo sigcina ukuhanjiswa kolwelo kuzinzile ngokuthintela umphunga ukuba ungangeni ngaphakathi kumxube—nokuba uxinzelelo lokungena lutsiba ukusuka kwi-0.3 ukuya kwi-1.6 MPa, kuxhomekeke kwindlela inkqubo esekwe ngayo.
Uza kubona ukuba kutheni oku kubalulekile kwiindawo ezifana nokuveliswa kwe-semiconductor (MBE, etching, wafer cooling), ii-terminals ze-LNG regasification, kunye ne-liquid nitrogen dosing kwimveliso yokutya neziselo.
Ngokwahlulwa kwesigaba okuthembekileyo, ufumana ukuhamba kobunzima okuqikelelweyo kwaye oko kunefuthe ngqo kwimveliso yenkqubo kunye nokuthobela ukhuseleko. Kumalunga nokugcina izinto zihamba kakuhle nangokukhuselekileyo.
●Ikhrayitheriya yoKhetho oluPhambili 4: Ukuthobela iMigangatho yoBunjineli beHlabathi
Ukuze uthathwe nzulu njengomthengisi we-cryogenic, kufuneka ubonise ukuba uyahlangabezana neekhowudi zamazwe ngamazwe.
Kwi-HL Cryogenics, asizisebenzisi kakhulu izinto. Sakha yonke into ngokwemigangatho ye-ASME yezixhobo zoxinzelelo, silandela imithetho ye-EN yokudibanisa i-EPC yaseYurophu, kwaye sinamathela kwiinkqubo ze-ISO zomgangatho kunye nokuwelda. Oko kuthetha ukuba izixhobo zethu zisebenza kakuhle neenkampani ze-EPC eYurophu, eMzantsi-mpuma Asia, nakuMbindi Mpuma—ezo ndawo apho ukuqinisekiswa kobunjineli kufuneka kuhlangabezane neemfuno ezinzima, eziwela imida.
Nantsi into eyenzekileyo kwiprojekthi yeziseko zophuhliso ze-LNG eMzantsi-mpuma Asia. Babefuna unikezelo lwe-nitrogen engamanzi oluzinzileyo ukuze balungiselele ukupholisa kwabo ngaphambi kokuba baphole. Kodwa inkampani yabo ye-EPC yadibana neentloko ezibuhlungu: utshintsho loxinzelelo kunye nokubila kakhulu, konke oku kungenxa yokuba ubushushu obuvela kwimibhobho yabo emidala, edibeneyo abuzange buyinqumle.
Singene saza satshintsha inkqubo safumana into eqinileyo: ulungiselelo oluhlanganisiweyo ngokupheleleyo oluneUmbhobho ogqunywe nge-vacuum, Umbhobho oguquguqukayokunyeIsahluli seSigaba—zonke zixhaswa yiInkqubo yePompo yeDynamic Vacuumukugcina i-vacuum izinzile ngokuhamba kwexesha.
Iziphumo bezicacile. Ukuvuza kobushushu kwehle malunga ne-85%. Uxinzelelo luhlale luzinzile, ngaphakathi kwe-±0.05 MPa. Ulondolozo? Sika umva kakhulu, ukusuka kumjikelo wokuqala.
Ngokwenene, oku kubonisa ukuba ubunjineli benqanaba lenkqubo yiyo eqhuba impumelelo ye-EPC—ingekuko nje ukutshintshana ngamacandelo ngamanye.
