Txheej Txheem Cej Luam: Qhov Project Transformation ntawm Yangtze River mus rau Huaihe River
Ua ib qho project txuag dej tseem ceeb hauv tebchaws, Yangtze River mus rau Huaihe River Diversion Project yog ib qho project loj loj uas muaj cov haujlwm tseem ceeb ntawm kev muab dej hauv nroog thiab nyob deb nroog thiab kev txhim kho Yangtze-Huaihe River shipping, ua ke nrog kev ywg dej thiab kev rov ua kom dej rov qab zoo thiab kev txhim kho ib puag ncig ntawm Chaohu Lake thiab Huaihe River. Los ntawm sab qab teb mus rau sab qaum teb, nws muab faib ua peb ntu: Yangtze River mus rau Chaohu, kev sib txuas lus ntawm Yangtze-Huaihe River, thiab Yangtze River dej mus rau sab qaum teb. Tag nrho qhov ntev ntawm txoj kab xa dej yog 723 kilometers, suav nrog 88.7 kilometers ntawm cov kwj dej tshiab, 311.6 kilometers ntawm cov dej thiab pas dej uas twb muaj lawm, 215.6 kilometers ntawm kev khawb thiab nthuav dav, thiab 107.1 kilometers ntawm cov kav dej siab.
Hauv thawj theem ntawm qhov project, Liancheng Group tau muab cov twj loj ob chav nqus dej thiab cov twj axial flow rau ntau ntu ntawm Yangtze River mus rau Huaihe River Diversion Project. Qhov project no yog ib feem ntawm theem ob ntawm Yangtze River mus rau Huaihe River Diversion Project. Nws yog raws li theem thawj zaug ntawm Yangtze River mus rau Huaihe River Diversion Project, tsom mus rau kev muab dej hauv nroog thiab thaj chaw deb nroog, ua ke nrog kev ywg dej thiab kev rov ua kom dej rov qab, los tsim cov xwm txheej rau thaj av los teb rau kev pheej hmoo kev nyab xeeb ntawm kev muab dej thiab txhim kho ib puag ncig ecological. Nws muab faib ua ob ntu tseem ceeb: txoj kab xa dej thiab kev muab dej rov qab. Hom twj tseem ceeb ntawm qhov project yeej yog lub twj ob chav nqus dej, uas muab cov twj tso kua dej thiab cov khoom siv hydraulic mechanical auxiliary system rau Tongcheng Sanshui Plant, Daguantang thiab Wushui Plant cov dej num muab dej, thiab Wanglou Station. Raws li qhov yuav tsum tau muab, 3 lub twj ob chav nqus dej rau Tongcheng Sanshui Plant yog thawj pawg khoom siv, thiab qhov seem yuav raug muab maj mam raws li qhov yuav tsum tau ua.
Cov kev cai ua haujlwm ntawm thawj pawg twj dej uas Liancheng Group muab rau Tongcheng Sanshui Plant yog raws li nram no:
Liancheng Solution: Yangtze River mus rau Huaihe River Diversion Project
Suab nrov thiab kev co zoo heev
Liancheng Group yeej ib txwm muab cov khoom zoo thiab cov kev daws teeb meem zoo rau Yangtze River mus rau Huaihe River Diversion Project. Qhov project no muaj cov kev cai nruj heev ntawm cov cim qhia txog kev siv tshuab ntawm txhua qhov project ntawm lub twj tso kua dej. Cov neeg siv khoom them sai sai rau qhov suab nrov, thiab yuav tsis lees txais nws yog tias nws tsis ncav cuag 85 decibels. Rau lub twj tso kua dej, lub suab nrov ntawm lub cev muaj zog feem ntau ntau dua li lub twj tso kua dej. Yog li ntawd, hauv qhov project no, tus neeg tsim khoom lub cev muaj zog yuav tsum tau txais kev tsim qauv txo suab nrov rau lub cev muaj zog siab, thiab nws yog qhov tsim nyog los ua qhov kev ntsuas suab nrov ntawm lub Hoobkas lub cev muaj zog. Tom qab lub suab nrov ntawm lub cev muaj zog tau tsim nyog, nws yuav raug xa mus rau lub Hoobkas twj tso kua mis.
Liancheng tau tsim cov chav ruaj khov uas tshaj qhov kev cia siab rau ntau qhov project, tshwj xeeb tshaj yog hais txog kev co thiab suab nrov ntawm cov twj tso kua dej. Lub 500S67 ntawm Tongcheng Sanshui Plant muaj 4-qib ceev. Liancheng Group tau teeb tsa cov tswv cuab ntawm pab pawg project thiab pab pawg engineering los tuav lub rooj sib tham los tham txog yuav ua li cas txo qhov suab nrov ntawm lub twj tso kua dej, thiab tsim kom muaj kev xav thiab kev npaj ua ke. Thaum kawg, txhua qhov ntsuas ntawm kev co thiab suab nrov ntawm lub twj tso kua dej tau ua raws li qhov yuav tsum tau ua thiab mus txog qib siab thoob ntiaj teb. Cov nqi co thiab suab nrov tau qhia hauv cov lus hauv qab no:
Kev tsim hydraulic ua haujlwm tau zoo thiab txuag hluav taws xob
Hais txog kev tsim hydraulic, cov neeg ua haujlwm R&D tau xaiv cov qauv hydraulic zoo heev rau thawj qhov kev tsim thiab siv 3D software Solidworks rau kev ua qauv. Los ntawm cov txheej txheem kos duab qauv tsim nyog, qhov du thiab du ntawm cov dej ntws ntawm cov qauv nyuaj xws li lub chamber nqus thiab lub chamber siab tau ua kom ntseeg tau, thiab qhov sib xws ntawm 3D thiab 2D siv los ntawm CFD tau ua kom ntseeg tau, yog li txo qhov yuam kev tsim qauv hauv theem R&D thaum ntxov.
Thaum lub sijhawm R&D, qhov kev ua haujlwm cavitation ntawm lub twj tso kua dej tau raug kuaj xyuas, thiab qhov kev ua haujlwm ntawm txhua qhov chaw ua haujlwm uas daim ntawv cog lus xav tau tau raug kuaj xyuas siv CFD software. Tib lub sijhawm, los ntawm kev txhim kho cov qauv geometric xws li impeller, volute thiab thaj chaw piv, qhov kev ua haujlwm ntawm lub twj tso kua dej ntawm txhua qhov chaw ua haujlwm tau maj mam txhim kho, yog li ntawd lub twj tso kua dej muaj cov yam ntxwv ntawm kev ua haujlwm siab, ntau yam thiab kev ua haujlwm siab thiab kev txuag hluav taws xob. Cov txiaj ntsig kawg ntawm kev xeem qhia tau tias txhua qhov ntsuas tau mus txog qib siab thoob ntiaj teb.
Txhim khu kev qha thiab ruaj khov qauv
Hauv qhov project no, cov khoom tseem ceeb xws li lub cev twj tso kua mis, impeller, thiab lub qhov twj tso kua mis tau raug suav los ntawm kev txheeb xyuas lub zog siv txoj kev finite element kom ntseeg tau tias qhov kev ntxhov siab hauv txhua qhov tsis tshaj qhov kev ntxhov siab uas tso cai ntawm cov khoom siv. Qhov no muab kev lees paub rau qhov zoo ntawm lub twj tso kua mis dej kom muaj kev nyab xeeb, txhim khu kev qha, thiab ruaj khov.
Cov txiaj ntsig thawj zaug
Rau qhov project no, Liancheng Group tau tswj hwm nruj me ntsis rau kev tsim pwm, kev tshuaj xyuas dawb paug, kev tshuaj xyuas cov khoom siv thiab kev kho cua sov ntawm lub twj tso kua dej txij thaum pib ntawm qhov project, kev ua tiav ntxhib thiab zoo, kev sib tsoo, kev sib dhos, kev sim thiab lwm yam ntsiab lus.
Thaum Lub Yim Hli 26, 2024, tus neeg siv khoom tau mus rau Liancheng Group Suzhou Industrial Park los ua tim khawv rau qhov kev ntsuam xyuas kev ua tau zoo ntawm lub twj tso kua dej 500S67 ntawm Tongcheng Sanshui Plant. Cov kev ntsuam xyuas tshwj xeeb suav nrog kev ntsuam xyuas dej siab, kev sib npaug ntawm lub rotor dynamic, kev ntsuam xyuas cavitation, kev ntsuam xyuas kev ua tau zoo, kev nce qhov kub ntawm cov kabmob, kev ntsuam xyuas suab nrov, thiab kev ntsuam xyuas kev co.
Lub rooj sib tham lees txais zaum kawg ntawm qhov project tau muaj nyob rau lub Yim Hli 28. Hauv lub rooj sib tham no, cov ntsuas kev ua tau zoo ntawm lub twj tso kua dej thiab kev siv zog los ntawm cov neeg Liancheng tau lees paub zoo los ntawm chav tsev tsim kho thiab Tog A.
Yav tom ntej, Liancheng Group yuav ua haujlwm tsis tu ncua thiab ua siab ntev los muab cov kev daws teeb meem zoo thiab cov khoom lag luam zoo rau ntau qhov dej num txuag dej.
