U-Hien ufumene udumo oluphezulu ngenxa yeprojekthi ye-60203 ㎡ yeSitishi se-Qinghai Expressway. Ndiyabulela kuloo nto, izikhululo ezininzi zeQinghai zoNxibelelwano kunye neQela loKwakha zikhethe iHien ngokufanelekileyo.
IQinghai, elinye lamaphondo abalulekileyo eQinghai-Tibet Plateau, luphawu lokubanda kakhulu, ukuphakama okuphezulu kunye noxinzelelo oluphantsi. UHien ukhonze ngempumelelo izikhululo zerhasi ezingama-22 zeSinopec kwiPhondo laseQinghai ngo-2018, kwaye ukusuka ngo-2019 ukuya kowama-2020, iHien yakhonza ngaphezulu kwezikhululo zerhasi ezingama-40 eQinghai enye emva kwenye, ebisebenza ngokuzinzileyo nangokufanelekileyo, eyaziwayo kweli shishini.
Ngo-2021, iiyunithi zokufudumala zempompo yomoya we-Hien zakhethwa kwiprojekthi yokuphucula ukufudumeza kwe-Haidong Branch kunye ne-Huangyuan yeSebe le-Qinghai Expressway Management kunye neZiko lokuSebenza. Indawo yokufudumeza iyonke yi-60,203 square metres. Ekupheleni kwexesha lokufudumeza, iiyunithi zeprojekthi zazinzile kwaye zisebenza kakuhle. Kulo nyaka, uLawulo lweNdlela ye-Haidong, uLawulo lweNdlela ye-Huangyuan kunye ne-Huangyuan Service Zone, ekwayeyoNxibelelwano lweQinghai kunye neQela loKwakha, bakhethe iiyunithi zokufudumala zempompo yobushushu be-Hien emva kokufunda umphumo wokusebenza kwempompo yokushisa ye-Hien kwisikhululo se-Qinghai Expressway.
Ngoku, makhe sifunde ngakumbi malunga neprojekthi yesikhululo esinesantya esiphezulu sikaHien eQinghai Expressway Management and Operation Centre.
Isishwankathelo seProjekthi
Kuyaqondwa ukuba ezi zikhululo zesantya esiphezulu zazifudunyezwa kuqala ngamabhoyili e-LNG. Emva kophando lwendawo, iingcali zeHien eQinghai zifumene iingxaki kunye neempazamo kwinkqubo yokufudumeza kwezi zikhululo zesantya esiphezulu. Okokuqala, imibhobho yesebe yokufudumeza yasekuqaleni yayiyi-DN15 yonke, eyayingenako ukuhlangabezana neemfuno zokufudumeza konke; okwesibini, uthungelwano lombhobho wokuqala wesiza uye wagqwala kwaye udliwe ngokunzulu, awunakusetyenziswa ngokuqhelekileyo; okwesithathu, amandla okuguqula isikhululo awanelanga. Ngokusekelwe kule miqathango kunye nokuqwalasela izinto zendalo zendalo ezifana nokubanda okukhulu kunye nokuphakama okuphezulu, iqela le-Hien litshintshe umbhobho wesebe le-radiator yokuqala kwi-DN20; buyisela yonke inethiwekhi yombhobho yomhlwa; ukwandisa umthamo we-transformer kwisiza; kunye nokuxhobisa izixhobo zokufudumeza ezibonelelwe kwisiza ngamatanki amanzi, iimpompo, ukuhanjiswa kwamandla kunye nezinye iinkqubo.
Uyilo lweProjekthi
Inkqubo ithatha ifom yokufudumeza "inkqubo yokufudumeza okujikelezayo", oko kukuthi "injini engundoqo + yesiphelo". Inzuzo yayo ilele kulawulo oluzenzekelayo kunye nolawulo lwendlela yokusebenza, apho inkqubo yokufudumala esetyenziswa ebusika ineenzuzo ezifana nokuzinza okuhle kwe-thermal kunye nomsebenzi wokugcina ukushisa; Ukusebenza okulula, ukusetyenziswa okufanelekileyo, kwaye kukhuselekile kwaye kuthembekile; Uqoqosho kunye nokusebenza, iindleko zokugcinwa okuphantsi, ubomi benkonzo ende, njl. Unikezelo lwamanzi lwangaphandle kunye nokuhanjiswa kwamanzi kwiimpompo zobushushu zixhotyiswe ngeenkqubo zokunqanda ukukhenkceza, kunye nezixhobo zempompo zokufudumala zixhotyiswe ngesixhobo esithembekileyo sokunciphisa i-frosting yokulawula. Isixhobo ngasinye siya kufakwa kunye neepads ezithintela ukothuka ezenziwe ngezinto zerabha ukunciphisa ingxolo. Oku kunokonga iindleko zokuqhuba.
Ukubalwa komthwalo wokufudumeza: ngokwendawo ebanda kakhulu kunye nokuphakama okuphezulu kwendawo kunye neemeko zemozulu yendawo, umthwalo wokufudumeza ebusika ubalwa njenge-80W/㎡.
Kwaye ukuza kuthi ga ngoku, i-Hien yomthombo womoya wempompo yokufudumala iiyunithi zokufudumeza bezisebenza ngokuzinzileyo ngaphandle kokusilela okoko kufakelo.
Isiphumo sosetyenziso
Iiyunithi zokufudumeza impompo yobushushu yomthombo womoya weHien kule projekthi zisetyenziswa kwicandelo elinobude obungama-3660 square metres kwiSikhululo saseQinghai Expressway. Iqondo lokushisa eliqhelekileyo ngexesha lokufudumeza li-18 °, kwaye iqondo lokushisa elibandayo li-28 °. Ixesha lokufudumeza lonyaka omnye ziinyanga ezisi-8. Ukushisa kwegumbi malunga ne-21 °, kwaye ixabiso lexesha lokufudumeza liyi-2.8 yuan / m2 ngenyanga, eyi-80% yokulondoloza amandla ngaphezu kwebhoyili ye-LNG yasekuqaleni. Inokubonwa kumanani okubalwe kwangaphambili ukuba umsebenzisi unokubuyisela iindleko emva kwexesha lokufudumeza kwe-3 kuphela.
