Chidule cha Ntchito: Yangtze River kupita ku Huaihe River Diversion Project
Monga pulojekiti yayikulu yosungira madzi, mtsinje wa Yangtze kupita ku Huaihe River Diversion Project ndi ntchito yayikulu yopatutsa madzi m'mabeseni omwe ali ndi ntchito yayikulu yoperekera madzi akumidzi ndi akumidzi komanso chitukuko cha zombo zapamadzi za Yangtze-Huaihe, kuphatikiza ulimi wothirira. ndi kubwezeretsanso madzi komanso kukonza chilengedwe cha Nyanja ya Chaohu ndi Mtsinje wa Huaihe. Kuchokera kumwera mpaka kumpoto, agawidwa m'magawo atatu: Mtsinje wa Yangtze kupita ku Chaohu, kulumikizana kwa Mtsinje wa Yangtze-Huaihe, ndi kulowera kumtsinje wa Yangtze kumpoto. Kutalika konse kwa mzere wotumizira madzi ndi makilomita 723, kuphatikiza ma kilomita 88.7 a ngalande zatsopano, makilomita 311.6 a mitsinje ndi nyanja zomwe zilipo, ma kilomita 215.6 a kukhetsa ndi kukulitsa, ndi 107.1 makilomita amapaipi opanikizika.
Mu gawo loyamba la polojekitiyi, Liancheng Group yapereka mapampu akuluakulu otsekemera kawiri ndi mapampu a axial otaya magawo angapo a mtsinje wa Yangtze kupita ku Huaihe River Diversion Project. Ntchitoyi ndi ya gawo lachiwiri la mtsinje wa Yangtze kupita ku Huaihe River Diversion Project. Zimakhazikitsidwa ndi gawo loyamba la Mtsinje wa Yangtze kupita ku Huaihe River Diversion Project, ikuyang'ana kwambiri madzi akumidzi ndi akumidzi, kuphatikizapo ulimi wothirira ndi kubwezeretsanso madzi, kuti apange mikhalidwe yoti chigawochi chiyankhe kuopsa kwa chitetezo cha madzi ndikuwongolera chilengedwe. . Imagawidwa m'magawo awiri akuluakulu: thunthu la thunthu la madzi ndi madzi am'mbuyo. Mtundu waukulu wa mpope wa polojekiti yopambana ndi mpope woyamwa kawiri, womwe umapereka zida zopopera madzi ndi zida za hydraulic mechanical auxiliary system za Tongcheng Sanshui Plant, Daguantang ndi Wushui Plant water supply, ndi Wanglou Station. Malinga ndi zofunikira zogulitsira, mapampu atatu oyamwa kawiri a Tongcheng Sanshui Plant ndiye gulu loyamba lazinthu, ndipo zotsalazo zidzaperekedwa pang'onopang'ono malinga ndi zofunikira.
Zofunikira pagawo loyamba la mapampu amadzi operekedwa ndi Liancheng Gulu ku Tongcheng Sanshui Plant ndi motere:
Liancheng Solution: Yangtze River to Huaihe River Diversion Project
Phokoso Labwino Kwambiri ndi Kugwedezeka
Gulu la Liancheng lakhala likupereka zinthu zapamwamba kwambiri komanso njira zothetsera mtsinje wa Yangtze kupita ku Huaihe River Diversion Project. Pulojekitiyi ili ndi zofunikira zokhwima kwambiri pa zizindikiro zaumisiri za polojekiti iliyonse yapampu yamadzi. Makasitomala amalabadira kwambiri mtengo waphokoso, ndipo sangavomereze ngati sichifika ma decibel 85. Pagawo la mpope wamadzi, phokoso la mota nthawi zambiri limakhala lalikulu kuposa la mpope wamadzi. Chifukwa chake, mu pulojekitiyi, wopanga magalimoto amayenera kutengera kapangidwe kake kochepetsa phokoso lamoto wothamanga kwambiri, ndipo ndikofunikira kuyesa kuyesa kwaphokoso pafakitale yamagalimoto. Phokoso la injini likatha, lidzatumizidwa ku fakitale ya mpope.
Liancheng adapanga mayunitsi okhazikika omwe amapitilira zomwe amayembekeza pama projekiti ambiri, makamaka pankhani ya kugwedezeka komanso phokoso la pampu zamadzi. 500S67 ya Tongcheng Sanshui Plant ili ndi liwiro la 4-level. Gulu la Liancheng linalinganiza mamembala a gulu la polojekiti ndi magulu a uinjiniya kuti achite msonkhano kuti akambirane momwe angachepetsere phokoso la mpope wamadzi, ndipo adapanga lingaliro logwirizana ndi dongosolo. Pamapeto pake, zisonyezo zonse za kugwedezeka ndi phokoso la pampu yamadzi zidakwaniritsa zofunikira ndikufikira pamlingo wapadziko lonse lapansi. Kugwedera ndi phokoso zikuwonetsedwa patebulo ili:
Mapangidwe apamwamba kwambiri komanso opulumutsa mphamvu zama hydraulic
Pankhani ya kamangidwe ka ma hydraulic, ogwira ntchito ku R&D adasankha mitundu yabwino kwambiri yama hydraulic pamapangidwe oyamba ndikugwiritsa ntchito pulogalamu ya 3D Solidworks potengera. Kupyolera mu njira zojambulira zachitsanzo zololera, kusalala ndi kusalala kwa mawonekedwe oyenda amitundu yovuta monga chipinda choyamwa ndi chipinda choponderezedwa zidatsimikizika, komanso kusasinthika kwa 3D ndi 2D yogwiritsidwa ntchito ndi CFD kudatsimikizika, potero kumachepetsa zolakwika zamapangidwe mu gawo loyambirira la R&D.
Pa gawo la R&D, ntchito ya cavitation ya mpope wamadzi idayang'aniridwa, ndipo magwiridwe antchito aliwonse omwe amafunidwa ndi mgwirizano adafufuzidwa pogwiritsa ntchito pulogalamu ya CFD. Panthawi imodzimodziyo, pokonza magawo a geometric monga chiŵerengero cha impeller, volute ndi dera, mphamvu ya mpope wamadzi pa malo aliwonse opangira ntchito inasinthidwa pang'onopang'ono, kotero kuti mpope wamadzi uli ndi makhalidwe apamwamba, osiyanasiyana komanso apamwamba. bwino komanso kupulumutsa mphamvu. Zotsatira zomaliza zoyesa zikuwonetsa kuti zizindikiro zonse zafika pamlingo wapamwamba wapadziko lonse lapansi.
Mapangidwe odalirika komanso okhazikika
Mu pulojekitiyi, zigawo zazikuluzikulu monga thupi la pampu, impeller, ndi shaft shaft zonse zinayesedwa kuwerengera zotsimikizira mphamvu pogwiritsa ntchito njira yochepetsera kuti zitsimikizire kuti kupanikizika kwa gawo lililonse sikudutsa kupanikizika kovomerezeka kwa zinthuzo. Izi zimapereka chitsimikizo cha khalidwe lotetezeka, lodalirika, komanso lolimba la mpope wamadzi.
Zotsatira zoyambirira
Ntchito imeneyi, Liancheng Gulu ali mosamalitsa ankalamulira nkhungu kupanga, kuyendera akusowekapo, anayendera zinthu ndi kutentha mankhwala mpope madzi kuyambira chiyambi cha polojekiti, akhakula ndi kukonza bwino, akupera, msonkhano, kuyezetsa ndi zina.
Pa Ogasiti 26, 2024, kasitomala adapita ku Liancheng Gulu la Suzhou Industrial Park kukachitira umboni mayeso a index ya 500S67 pampu yamadzi ya Tongcheng Sanshui Plant. Mayesero apadera amaphatikizapo kuyesa kuthamanga kwa madzi, kuthamanga kwa rotor, kuyesa kwa cavitation, kuyesa kwa magwiridwe antchito, kukwera kwa kutentha, kuyesa kwa phokoso, ndi kuyesa kwa vibration.
Msonkhano womaliza wovomerezeka wa polojekitiyi unachitika pa August 28. Pamsonkhanowu, zizindikiro za ntchito ya mpope wa madzi ndi zoyesayesa za anthu a Liancheng zinazindikiridwa kwambiri ndi gulu la zomangamanga ndi Party A.
M'tsogolomu, Liancheng Group idzachita khama komanso kupirira kuti ipereke mayankho ogwira mtima ndi mankhwala apamwamba pa ntchito zambiri zosungira madzi.
