Hauv lub ntiaj teb kev tsim cov kav dej uas hloov zuj zus, cov txheej txheem vuam zoo yog qhov tseem ceeb, tshwj xeeb tshaj yog thaum nws los txog rau kev teeb tsa cov kav dej roj av. Raws li kev lag luam txuas ntxiv nrhiav cov kev daws teeb meem tshiab los txhim kho kev ua haujlwm zoo thiab kev nyab xeeb, kev tshawb nrhiav cov thev naus laus zis tshiab thiab cov txheej txheem rau kev vuam cov kav dej polyethylene (PE) tau dhau los ua qhov tseem ceeb. Cov blog no yuav siv sijhawm tob rau hauv qhov tseem ceeb ntawm cov txheej txheem vuam kom zoo, tshwj xeeb tshaj yog hauv kev siv vuam ntawm SSAW (Spiral Submerged Arc Welding) cov kav dej hlau, thiab lawv tuaj yeem ua kom muaj kev ncaj ncees ntawm cov kav dej roj av.
Lub plawv ntawm txhua qhov kev teeb tsa cov kav dej roj kom zoo yog cov txheej txheem vuam siv los txuas cov khoom sib txawv. Cov txheej txheem vuam yog qhov tseem ceeb vim nws ua kom ntseeg tau tias cov kav dej tuaj yeem tiv taus qhov siab thiab kev ntxhov siab uas tsim los ntawm kev thauj cov roj ntuj.SSAW yeeb nkab hlaupaub txog nws lub zog siab thiab ruaj khov thiab feem ntau siv rau hauv cov kav dej zoo li no. Txawm li cas los xij, qhov ua tau zoo ntawm cov kav dej no nyob ntawm qhov zoo ntawm cov txheej txheem vuam siv.
Cov kev nce qib tshiab hauv kev siv tshuab vuam tau ua rau muaj cov txheej txheem tshiab uas txhim kho kev ua haujlwm zoo thiab kev ntseeg siab ntawm kev vuam yeeb nkab polyethylene. Cov kev tsim kho tshiab no suav nrog cov txheej txheem vuam tsis siv neeg, uas tsis yog tsuas yog ua kom qhov ceev ntawm kev vuam nce ntxiv xwb tab sis kuj ua kom muaj kev raug zoo dua. Cov txheej txheem tsis siv neeg txo qhov kev pheej hmoo ntawm kev ua yuam kev ntawm tib neeg, ua rau muaj kev vuam zoo dua thiab cov yeeb nkab tag nrho muaj zog dua.
Ntxiv mus, kev sib koom ua ke ntawm cov khoom siv siab heev thiab cov thev naus laus zis vuam tau ua rau muaj kev sib raug zoo ntau dua ntawm cov yeeb nkab polyethylene thiab cov yeeb nkab steel spiral submerged arc welded. Qhov kev sib raug zoo no yog qhov tseem ceeb vim tias nws txo qhov kev pheej hmoo ntawm kev xau thiab kev ua tsis tiav uas yuav muaj kev puas tsuaj loj heev rau cov kab ke roj. Los ntawm kev tshawb nrhiav cov thev naus laus zis tshiab, cov tuam txhab tuaj yeem ua kom lawv cov txheej txheem vuam ua tau raws li cov qauv kev lag luam siab tshaj plaws, thaum kawg ua tiav kev xa roj zoo dua thiab muaj kev nyab xeeb dua.
Lub tuam txhab npog thaj tsam ntawm 350,000 square meters, muaj tag nrho cov cuab tam ntawm RMB 680 lab, thiab yog nyob rau pem hauv ntej ntawm kev tsim kho tshiab. Lub tuam txhab muaj 680 tus neeg ua haujlwm mob siab rau thiab tsim 400,000 tons ntawm cov kav hlau kauv txhua xyoo, nrog rau cov nqi tso tawm ntawm RMB 1.8 billion. Nrog peb txoj kev cog lus rau qhov zoo thiab kev tsim kho tshiab, peb txuas ntxiv tshawb nrhiav cov tshiabpe yeeb nkab vuamcov txheej txheem los xyuas kom meej tias peb cov khoom ua tau raws li cov kev cai nruj ntawm kev lag luam roj av.
Ntxiv rau kev nce qib ntawm thev naus laus zis, kev cob qhia thiab kev kawm tseem ceeb heev rau kev siv cov txheej txheem vuam tshiab kom zoo. Peb cov neeg ua haujlwm yuav tsum paub zoo txog cov txheej txheem tshiab thiab cov txheej txheem kev nyab xeeb. Los ntawm kev nqis peev rau hauv cov kev pab cuam kev cob qhia, peb ua rau peb cov neeg ua haujlwm muaj kev ntseeg siab los siv cov thev naus laus zis tshiab thiab xyuas kom meej tias lawv tuaj yeem ua cov txheej txheem vuam nrog kev ua tib zoo thiab kev saib xyuas.
Saib mus tom ntej, kev tshawb nrhiav cov thev naus laus zis tshiab thiab cov txheej txheem rau kev vuam yeeb nkab polyethylene yuav tseem yog qhov tseem ceeb rau peb. Kev lag luam roj av niaj hnub hloov pauv, thiab kev nyob ua ntej ntawm qhov nkhaus yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo. Los ntawm kev lees txais kev tsim kho tshiab thiab kev muab qhov tseem ceeb rau qhov zoo hauv peb cov txheej txheem vuam, peb tuaj yeem pab txhawb kev tsim cov khoom siv xa roj uas txhim khu kev qha thiab ruaj khov dua.
Hauv kev xaus lus, cov txheej txheem vuam yeeb nkab kom raug yog qhov tseem ceeb hauv kev teeb tsa cov kav dej roj av. Los ntawm kev tshawb nrhiav cov thev naus laus zis tshiab thiab cov txheej txheem, tshwj xeeb tshaj yog hauv kev ua haujlwm ntawm cov yeeb nkab hlau vuam uas siv lub submerged arc, peb tuaj yeem txhim kho kev ncaj ncees thiab kev nyab xeeb ntawm cov kav dej roj av. Peb lub tuam txhab cog lus tias yuav ua tus thawj coj hauv kev txhim kho ntawm daim teb no kom ntseeg tau tias peb txuas ntxiv muab cov khoom lag luam zoo thiab cov kev pabcuam rau cov neeg siv khoom hauv kev lag luam roj av.
