Ukubuka Konke Kwephrojekthi: Iphrojekthi Yokuphambuka Komfula iYangtze kuya eHuaihe
Njengomsebenzi kazwelonke obalulekile wokulondolozwa kwamanzi, i-Yangtze River Diversion Project iwumsebenzi omkhulu wokuphambukisa amanzi phakathi kwezizinda ezinemisebenzi eyinhloko yokuphakelwa kwamanzi emadolobheni nasemakhaya kanye nokuthuthukiswa kokuthunyelwa koMfula iYangtze-Huaihe, kuhlanganiswe nokunisela nokugcwaliswa kwamanzi kanye nokuthuthukiswa kwendawo ezungezile yeLake Chaohu kanye noMfula iHuaihe. Kusukela eningizimu kuya enyakatho, ihlukaniswe ngezigaba ezintathu: uMfula iYangtze ukuya eChaohu, ukuxhumana koMfula iYangtze-Huaihe, kanye nokudluliswa kwamanzi oMfula iYangtze ukuya enyakatho. Ubude obuphelele bomugqa wokudlulisa amanzi bungamakhilomitha angu-723, kufaka phakathi amakhilomitha angu-88.7 emisele emisha, amakhilomitha angu-311.6 emifula namachibi akhona, amakhilomitha angu-215.6 okudonsa amanzi nokwandisa, kanye namakhilomitha angu-107.1 amapayipi okucindezela.
Esigabeni sokuqala sale phrojekthi, iLiancheng Group inikeze amaphampu amakhulu okumunca kabili kanye namaphampu okugeleza kwe-axial ezingxenyeni eziningi zeProjekthi Yokuphambuka Komfula iYangtze kuya eHuaihe River. Le phrojekthi ingeyesigaba sesibili seProjekthi Yokuphambuka Komfula iYangtze kuya eHuaihe River. Isekelwe esigabeni sokuqala seProjekthi Yokuphambuka Komfula iYangtze kuya eHuaihe River, igxile ekuhlinzekweni kwamanzi emadolobheni nasemakhaya, kuhlanganiswe nokunisela kanye nokugcwaliswa kwamanzi, ukudala izimo zesifunda ukuze siphendule ezingozini zokuphepha kokuhlinzekwa kwamanzi futhi sithuthukise indawo ezungezile. Ihlukaniswe ngezigaba ezimbili ezinkulu: umugqa wesiqu sokudlulisa amanzi kanye nokuhlinzekwa kwamanzi okuyisisekelo. Uhlobo oluyinhloko lwephampu yephrojekthi ewinile yiphampu yokumunca kabili, ehlinzeka ngamayunithi okumunca amanzi kanye nemishini yesistimu yokusiza ye-hydraulic mechanical yeTongcheng Sanshui Plant, amaphrojekthi okuphakelwa kwamanzi eDaguantang kanye neWushui Plant, kanye neWanglou Station. Ngokwezidingo zokuphakelwa, amaphampu okumunca kabili amathathu eTongcheng Sanshui Plant ayiqoqo lokuqala lezinto ezidingekayo, kanti okunye kuzohlinzekwa kancane kancane ngokwezidingo.
Izidingo zepharamitha yokusebenza kweqoqo lokuqala lamaphampu amanzi ahlinzekwa yiLiancheng Group eTongcheng Sanshui Plant yilezi ezilandelayo:
Isixazululo se-Liancheng: Umfula iYangtze ukuya kuphrojekthi ye-Huaihe River Diversion
Umsindo Omuhle Kakhulu Nokudlidliza
I-Liancheng Group ibilokhu ihlinzeka ngemikhiqizo esezingeni eliphezulu kanye nezixazululo ezisebenzayo zephrojekthi yokuphambuka koMfula iYangtze kuya kuMfula iHuaihe. Le phrojekthi inezidingo eziqinile kakhulu ezinkombeni zobuchwepheshe zephrojekthi ngayinye yeyunithi yephampu yamanzi. Amakhasimende anaka kakhulu inani lomsindo, futhi ngeke alamukele uma lingafiki kuma-decibel angu-85. Kwiyunithi yephampu yamanzi, umsindo wemoto ngokuvamile umkhulu kunowompompi wamanzi. Ngakho-ke, kulo mklamo, umenzi wemoto kudingeka ukuthi amukele umklamo wokunciphisa umsindo wemoto enamandla aphezulu, futhi kuyadingeka ukwenza ukuhlolwa kokulinganisa umsindo womthwalo efektri yemoto. Ngemuva kokuthi umsindo wemoto usufanelekile, uzothunyelwa efektri yephampu.
I-Liancheng iklame amayunithi azinzile adlula okulindelwe kumaphrojekthi amaningi, ikakhulukazi maqondana nokudlidliza nomsindo wamaphampu amanzi. I-500S67 yeTongcheng Sanshui Plant inesivinini esinamazinga amane. I-Liancheng Group ihlele amalungu eqembu lephrojekthi namaqembu obunjiniyela ukubamba umhlangano ukuze kuxoxwe ngendlela yokunciphisa umsindo wephampu yamanzi, futhi yakha umbono kanye nohlelo oluhlangene. Ekugcineni, zonke izinkomba zamanani okudlidliza nomsindo wephampu yamanzi zahlangabezana nezidingo futhi zafinyelela ezingeni elithuthukile lomhlaba wonke. Amanani okudlidliza nomsindo aboniswe kuthebula elilandelayo:
Umklamo we-hydraulic osebenza kahle kakhulu futhi osindisa amandla
Ngokuphathelene nomklamo we-hydraulic, abasebenzi be-R&D bakhethe amamodeli amahle kakhulu e-hydraulic kumklamo wokuqala futhi basebenzisa isofthiwe ye-3D i-Solidworks yokwenza amamodeli. Ngezindlela zokudweba imodeli ezinengqondo, ukushelela kanye nokushelela kwezindawo zesiteshi sokugeleza kwamamodeli ayinkimbinkimbi njengegumbi lokumunca kanye negumbi lokucindezela kwaqinisekiswa, futhi ukuvumelana kwe-3D kanye ne-2D esetshenziswa yi-CFD kwaqinisekiswa, ngaleyo ndlela kunciphisa iphutha lokuklama esigabeni sokuqala se-R&D.
Ngesikhathi sesigaba se-R&D, ukusebenza kwephampu yamanzi kuhlolwe, futhi ukusebenza kwendawo ngayinye yokusebenza edingekayo yinkontileka kuhlolwe kusetshenziswa isofthiwe ye-CFD. Ngesikhathi esifanayo, ngokuthuthukisa amapharamitha ejometri njengesilinganiso se-impeller, i-volute kanye nendawo, ukusebenza kahle kwephampu yamanzi endaweni ngayinye yokusebenza kwathuthukiswa kancane kancane, ukuze iphampu yamanzi ibe nezici zokusebenza kahle kakhulu, ububanzi obubanzi kanye nokusebenza kahle kakhulu nokonga amandla. Imiphumela yokugcina yokuhlola ikhombisa ukuthi zonke izinkomba sezifinyelele ezingeni eliphakeme lomhlaba wonke.
Isakhiwo esithembekile nesizinzile
Kulo msebenzi, izingxenye eziyinhloko ezifana nomzimba wephampu, impeller, kanye nomgodi wephampu zonke zahlolwa ukuze kuqinisekiswe amandla kusetshenziswa indlela ye-finite element ukuqinisekisa ukuthi ukucindezeleka engxenyeni ngayinye akudluli ukucindezeleka okuvunyelwe kwezinto. Lokhu kunikeza isiqinisekiso sekhwalithi ephephile, ethembekile, nehlala isikhathi eside yephampu yamanzi.
Imiphumela yokuqala
Kulo msebenzi, i-Liancheng Group ilawule ngokuqinile ukukhiqizwa kwesikhunta, ukuhlolwa okungenalutho, ukuhlolwa kwezinto kanye nokwelashwa kokushisa kwephampu yamanzi kusukela ekuqaleni kwephrojekthi, ukucubungula okungahlelekile nokucolekile, ukugaya, ukuhlanganisa, ukuhlola kanye neminye imininingwane.
Ngomhlaka-26 Agasti 2024, ikhasimende laya eLiancheng Group Suzhou Industrial Park ukuyobona ukuhlolwa kokusebenza kwephampu yamanzi engu-500S67 yeTongcheng Sanshui Plant. Ukuhlolwa okukhethekile kufaka phakathi ukuhlolwa komfutho wamanzi, ibhalansi ye-rotor dynamic, ukuhlolwa kwe-cavitation, ukuhlolwa kokusebenza, ukuphakama kokushisa kwamabhere, ukuhlolwa komsindo, kanye nokuhlolwa kokudlidliza.
Umhlangano wokugcina wokwamukela lo msebenzi wabanjwa ngomhlaka-28 Agasti. Kulo mhlangano, izinkomba zokusebenza kwephampu yamanzi kanye nemizamo eyenziwe ngabantu baseLiancheng kwaqashelwa kakhulu yiyunithi yokwakha kanye neQembu A.
Esikhathini esizayo, iLiancheng Group izokwenza imizamo engapheli futhi iphikelele ekuhlinzekeni ngezixazululo ezisebenzayo kanye nemikhiqizo esezingeni eliphezulu yamaphrojekthi amaningi okonga amanzi.
