Xa ukhetha ipayipi ye-cryogenic, kufuneka uqwalasele ngononophelo ukusebenza kwayo kobushushu, umlinganiselo woxinzelelo, kunye nendlela ehambelana kakuhle ngayo nenkqubo yakho. Ukuqinisekisa ukuba ulwelo lwe-cryogenic lushukunyiswa ngokukhuselekileyo nangokufanelekileyo, sicebisa ukuba umgangatho we-vacuum insulation, ukuhambelana kwezinto, kunye nozinzo lwe-vacuum oluhlala ixesha elide lube phezulu kuluhlu. Ukhetho olufanelekileyo lunefuthe elithe ngqo ekunciphiseni ukulahleka kobushushu, ukwenza umsebenzi ukhuseleke, kunye nokunciphisa iindleko zemveliso ebomini bayo bonke.
NgeUmbhobho oguquguqukayo ogqunywe nge-vacuum, ungahamba phakathi kwezinto ezizinzileyo nezishukumayo ngaphandle kokonakalisa inethiwekhi yepayipi e-cryogenic. Izisombululo eziguquguqukayo zinokuphatha ukungcangcazela, ukufinyela kobushushu, kunye nokunyamezela ukufakwa ngaphandle kokuchaphazela ukusebenza, ngokungafaniyo nokuqinaUmbhobho ogqunywe nge-vacuum.
Kwa-HL Cryogenics, siqinisekisa ukuba iinkqubo zethu zepayipi ye-cryogenic zisebenza ngokugqibeleleyo nezinye iimveliso, ezifana neIvalvu Egqunywe Ngomoya, Isahluli seSigaba esifakwe i-VacuumkunyeItanki encinciOku kuqinisekisa ukuba yonke inkqubo isebenza kakuhle, kungekhona inxalenye enye kuphela.
Eyona ngxaki inkulu yobunjineli kuyo nayiphi na inkqubo yokudlulisa i-cryogenic kukuthintela ubushushu ukuba bungangeni. Kukho iindlela ezintathu ubushushu obunokuhamba ngazo: ukuhanjiswa kombane, ukuhanjiswa kombane, kunye nokukhanya kwelanga.Umbhobho oguquguqukayo ogqunywe nge-vacuumisusa ngokupheleleyo i-convection ngokugcina umaleko ophezulu we-vacuum phakathi kwemibhobho yangaphakathi neyangaphandle.
Sisebenzisa i-multi-layer insulation (MLI) ukunciphisa ukudluliselwa kobushushu ngemitha ngakumbi, kwaye sisebenzisa izixhasi ezine-thermal conductivity ephantsi ukunciphisa ukuhanjiswa kobushushu ngakumbi. Iinkqubo ze-vacuum-insulated zinokunciphisa ukulahleka kobushushu ngaphezulu kwe-90% xa kuthelekiswa nombhobho oqhelekileyo we-cryogenic insulated. Oku kunciphisa kakhulu isantya apho iinkqubo ze-nitrogen ezingamanzi okanye iziseko ze-LNG zibila khona.
Ekusetyenzisweni kwegesi kwimizi-mveliso, oku kuthetha ukuba iindleko ziphantsi kwaye iinkqubo zizinzile ngakumbi.
Isiqulatho

●Uzinzo lweVacuum kunye nendima yeNkqubo yeDynamic Vacuum Pump
Ukuzinza kwe-vacuum ixesha elide yenye yezona zinto zibalulekileyo ekufuneka uzicinge xa ukhetha ipayipi ekhupha umoya. Ukuvuza okuncinci okanye ukuphuma kwegesi kunokubangela ukuba iinkqubo ezininzi zonakale ngokuhamba kwexesha, nto leyo evumela ubushushu obuninzi bungene kwaye bubenze bungasebenzi kakuhle.
ZethuInkqubo yePompo yeDynamic Vacuume-HL Cryogenics iyayinyamekela le nto. Le nkqubo yahlukile kwiindlela zoyilo lwe-vacuum ezingashukumiyo kuba ihlala ijonga kwaye igcina inqanaba le-vacuum. Oku kuqinisekisa ukuba i-vacuum insulation isebenza ngendlela efanayo kangangeminyaka.
Oku kubaluleke kakhulu kwiiprojekthi ezinkulu ezifana nee-terminals ze-LNG kuMzantsi-mpuma we-Asia okanye iiprojekthi ze-hydrogen kuMbindi Mpuma, apho kunzima ukufikelela kulungiso kwaye ixesha lokungasebenzi libiza kakhulu.
●Ukukhethwa kwezinto kunye noYilo lweMishini
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.
Ukukhetha izixhobo ezifanelekileyo kubaluleke kakhulu kwimigangatho yobunjineli be-cryogenic. Umbhobho wangaphakathi we-aUmbhobho oguquguqukayo ogqunywe nge-vacuumidla ngokwenziwa ngentsimbi engagqwaliyo (njenge-SS304 okanye i-SS316L) ngoko ke inokumelana namaqondo obushushu aphantsi kakhulu ngaphandle kokuqhekeka.
Ijakethi yangaphandle kufuneka igcine isakhiwo siqinile ngelixa igcina i-vacuum iqinile. Amacandelo aguquguqukayo enziwe ngentsimbi engagqwaliyo ebotshelelweyo ukuze akwazi ukugoba ngaphandle kokuzibeka uxinzelelo olukhulu.
Uvavanyo loxinzelelo kufuneka luhambelane noko kufunwa yinkqubo. Umzekelo:
Iinkqubo zokudlulisa i-LNG: zihlala ziphakathi kwe-150 kunye ne-300 yeepawundi zoxinzelelo
Iinkqubo ze-nitrogen ezingamanzi zifuna uxinzelelo oluncinci kodwa ukuhamba kwamanzi kuzinzile ngakumbi.
Siqinisekisa ukuba zonke izinto esiziyilileyo ziyahlangabezana nemigangatho yamazwe ngamazwe efana ne-ASME B31.3, i-EN 13480, kunye nemigangatho ye-ISO efanelekileyo. Oku kunika abakhi be-EPC kunye namaqela okuthenga uxolo lwengqondo.
●Ukhuseleko Lokusebenza Olulawulwa YiValve kunye neValve Box
Ukuhamba kunye noxinzelelo lwe-cryogenic liquids ngaphakathi kwenkqubo ye-HL Cryogenic vacuum jacketed pipe kulawulwa kusetyenziswa iivalvu ze-HL Cryogenic ezenziwe ngokukodwa. Ezi zixhobo zenzelwe ukusebenza ngokuthembekileyo phantsi kwamaqondo obushushu aphantsi kakhulu kunye notshintsho olukhawulezayo lobushushu.
Ukuphucula ngakumbi ukhuseleko kunye nokufikeleleka kwenkqubo, ivalvu nganye ye-HL Cryogenic igcinwe ngaphakathi kwebhokisi yevalvu ye-HL Cryogenic egqunyiweyo. Ibhokisi yevalvu ikhusela ivalvu ekungeneni komswakama, inciphisa ukwakheka kweqhwa, kwaye ivumela iingcali ukuba zenze uhlolo kunye nohlengahlengiso ngaphandle kokuphazamisa ibhalansi yobushushu kwiindawo ezingqongileyo.
Olu lwakhiwo luncinci, olunemodyuli lukwahambelana kakuhle nemida engqongqo yendawo eqhelekileyo kwizityalo zokupakisha ze-semiconductor kunye neendawo zokucoca.
Ngexesha lokufakelwa kwesakhiwo sesiphelo se-LNG kuMzantsi-mpuma we-Asia, sinikezele nge-hybrid yeUmbhobho ogqunywe nge-vacuumkwayeUmbhobho oguquguqukayo ogqunywe nge-vacuumkwipayipi ende eyi-12 km. Umthengi wethu ekuqaleni wayenengxaki yokufuma kwegesi kakhulu ngenxa yezisombululo zemveli zokugquma.
Ngokusebenzisa i-vacuum insulation yethu kunye ne-Inkqubo yePompo yeDynamic Vacuum, sikwazile ukunciphisa ukuvuza kobushushu malunga nama-85 ekhulwini. Oku kwenzeke ngenxaIvalvu Egqunywe NgomoyakwayeIsahluli seSigaba esifakwe i-Vacuum, nto leyo eyayithintela ukutshixa komphunga.
Yayiluphononongo oluphumeleleyo apho ukukhetha ipayipi echanekileyo yokukhupha ulwelo kwakubaluleke kakhulu.
●Ukudibanisa neeValve kunye nezixhobo zoLawulo lweSigaba
Umbhobho we-cryogenic awusebenzi wodwa; ukusebenza kwawo kuxhomekeke kakhulu ekulungelelanisweni kwawo nezinye izixhobo.
Iivalvu ezifakwe i-vacuumsusa naliphi na ithuba lokungena kobushushu kunye nokufuma okulandelayo. Kwelinye icala,Isahluli seSigaba esifakwe i-Vacuumiqinisekisa ukwahlulwa kwesigaba esifanelekileyo ngaphambi kokuba wondle izixhobo zokusetyenziswa kokugqibela ngento enyibilikisiweyo.
Oku kubaluleke kakhulu xa kujongwana neenkqubo ze-cryogenic kwizityalo ze-semiconductor eMpuma Asia, njengoko ukungahambelani kwesigaba esincinci kunokonakalisa imisebenzi ebuthathaka kwisityalo.
Iipayipi kufuneka zithathwe njengenxalenye yenkqubo yokudlulisa i-cryogenic edibeneyo ukuze kufumaneke iziphumo ezilungileyo zokusebenza.
Amacandelo ahlukeneyo aneemfuno ezahlukeneyo zeepayipi ze-cryogenic.
Icandelo le-LNG, ingakumbi eMzantsi-mpuma we-Asia, lifuna ukuba kubekho ubushushu obungcono ngenxa yemigama emide kunye namaqondo obushushu aphezulu. Kwiindawo zokuthengisa igesi zoshishino zaseYurophu, imigangatho yokhuseleko iba yingxaki ebalulekileyo ekufuneka iqwalaselwe.
Kwelinye icala, kwiiprojekthi ze-hydrogen zaseMbindi Mpuma, imiba yokungangeni kwamanzi kunye nokuhambelana kwezinto inika omnye umngeni. Ke ngoko, kwi-HL Cryogenics, sicinga ngetekhnoloji yesitywina kunye nezinto ezifunekayo ukuqinisekisa ukuba akukho kuvuza konke konke.
Kwi-HL Cryogenics, sisebenzisa indlela ejolise kwinkqubo apho sidibanisa khonaUmbhobho ofakwe i-Vacuum Insulated (VIP), iipayipi, iivalvu, kwanezisombululo zeetanki ezincinci.
●Imibuzo ebuzwa rhoqo
Ukususela ngo-1992, i-HL Cryogenics igxile kuyilo kunye nokuveliswa kweenkqubo zemibhobho ye-cryogenic egqunywe nge-vacuum ephezulu kunye nezixhobo zenkxaso ezinxulumene noko, ezenzelwe ukuhlangabezana neemfuno ezahlukeneyo zabathengi. Sineziqinisekiso ze-ASME, CE, kunye ne-ISO 9001, kwaye sinikezele ngeemveliso kunye neenkonzo kumashishini amaninzi aziwayo ngamazwe ngamazwe. Iqela lethu linyanisekile, linoxanduva, kwaye lizimisele ukugqwesa kuyo yonke iprojekthi esiyenzayo.
