Kev lag luam tsav tsheb muaj ntau txoj kev loj hlob
Kev tsav tsheb yog ib qho kev lag luam thiab kev lagluam hauv kev lag luam ntawm lub tebchaws. Cov tshuab hluav taws xob tawg yog cov tshwj xeeb siv los tsim rau hauv kev lag luam ntawm Tuam Tshoj lub tuam txhab thiab cov chaw lag luam ua lag luam nyob rau xyoo 1970. Lawv siv nyob rau hauv cov lag luam saum toj no, xws li cov kiv cua, twj thiab cov compressors. Cov cuab yeej hluav taws xob loj hauv tshuab cuab yeej.
Nyob rau hauv xyoo tsis ntev los no, nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj kev khwv nyiaj txiag, qhov kev thov rau cov tshuab hluav taws xob tawg nyob hauv cov chaw lag luam thiab cov tuam txhab lag luam muaj peev xwm nce ntxiv, uas tau nce lub ntiaj teb kev tawg tshuab. Tag nrho cov neeg tawg rog tawg yog cov loj hlob tuaj. Raws li tsis tiav cov txheeb cais, tam sim no muaj ntau tshaj li 100 tawm cov tshuab hluav taws xob tua cov khoom lag luam thiab 77 lub koom haum koom haum koom haum tawg. Feem ntau lawv tsis tsuas tsim cov khoom tawg, tab sis kuj tsim cov khoom siv cav zoo tib yam. Coal kuv lub cev muaj zog cov neeg tsim khoom lag luam rau 15% txog.
Nrhav kev lag luam kws nce nrawm nrhav tau nce rua lub zog, kws tau txhim tsa kev txhim khu rua kev siv zug ntawm kev ua haujlwm ntawm cov roj, roj av hab kev lag luam. Nyob rau tib lub sijhawm, cov av, roj av thiab cov chaw ua lag luam raug them nqi ntau dua rau kev nyab xeeb thiab cov khoom ua haujlwm kom zoo, thiab cov kev xav tau rau cov tshuab hluav taws xob tawg yog nce.
Los ntawm cov kev lag luam ntawm cov khoom lag luam, cov khoom siv hluav taws xob tshuab flameproof low-voltage motors account rau 86% ntawm tag nrho cov kev sib tsoo tshuab hluav taws xob, thiab qhov ua tau zoo ntawm nws cov khoom ua tau raws li kev siv zog ntawm Chav Kawm 3 ntawm GB18613. Ua kom raws li cov qauv ntawm cov qauv kawm tam sim no. Raws li lub zog hais txog kev siv hluav taws xob ua haujlwm GB18613, qhov ua tau zoo ntawm kev tsav tsheb hauv lub Xya Hli 2016 yuav tsum ua kom tau raws li theem 2 kev siv hluav taws xob.
Muaj ntau hom kev sib tsoo tawg, uas feem ntau siv flameproof, zoo siab, muaj kev nyab xeeb kom loj dua thiab tsis yog hom kab taws.
1. Cov tshuab hluav taws-tawg thiab cov tshuab muaj roj-tawg tau muaj ntau tshaj li ob npaug ntawm cov nqi hluav taws xob vim lawv cov qauv nyuab, thiab yuav tsum tau muaj kev txawj ntse thiab kev tswj theem ntawm kev tswj. Yog li, ntxiv nrog rau qhov muaj qhov muaj qhov phem nyob rau thaj tsam 1. Nyob hauv lwm qhov chaw muaj kev phom sij, tsis txhob siv cov cav siv los yog siv tsawg li tsawg tau.
2. Ua kom muaj kev nyab xeeb hom tawg-tawg pov tseg yog tsim kom muaj kub dua lub cav. Tsis tas li ntawd, hom cav no kuj muaj kev tswj tshwj xeeb rau kev tiv thaiv kev sib tw. Yog li, qhov kev siv lub tshuab no tsis yog txhua zaus siv.
3. Cov qauv ntawm cov hluav taws xob uas tsis yog nplawm tawg yog yuav luag ib yam li lub cav qub, tab sis qhov yuav tsum tau muaj kev tiv thaiv ntawm cov hlau sab nrauv thiab cov qauv ntawm lub thawv ntawv sib txuas. Tsis tas li ntawd, qee qhov kev ntsuas tau muab tso rau hauv cov txheej txheem tsim kev lag luam, yog li qhov kev ntseeg tau siab dua. Siab, nws tus nqi yog qhov qis tshaj plaws ntawm txhua yam kev sib tsoo hluav taws xob, tsuas yog me ntsis siab tshaj qhov qub cav; nws kuj yog li yooj yooj yim raws li cov cav hlau hauv kev txij nkawm, nws thiaj li siv tau rau thaj chaw muaj kev puas tsuaj ntawm thaj tsam 2.
Xyoo tas los no, cov neeg tseem ceeb ntawm kev sib tsoo hluav taws xob feem ntau tau tsis zoo ua haujlwm, uas ua rau lub khw muag khoom poob qis dua rau lub tshuab hluav taws xob tag nrho. Txoj kev lag luam yog kev sib tw sib tw, kev nyiaj txiag tag nrho tseem pheej tsis kam, thiab kev khiav hauj lwm kom muaj zog.
Thaum tam sim no, lub ntsiab yam tseem ceeb rau theem ntawm Tuam Tshoj lub me me thiab medium-qhov loj me lub cev khoom yog tsis ruaj tsis khov, tshwj xeeb tshaj yog qhov zoo ntawm silicon steel nplooj ntawv. Tsis tas li ntawd, lub tshuab hlwb hlau pauv feem ntau tsis tshuav lag luam, feem cuam tshuam ntawm cov cuab yeej cuab tam rau cov khoom siv loj, thiab qhov kev txiav txim siab tsis siab, uas yog ib qho ntawm cov txheej xwm uas cuam tshuam rau qhov zoo ntawm lub tshuab. Tsis tas li ntawd, tseem muaj qhov sib txawv nruab nrab ntawm txoj kev tsim txhua yam ntawm kev lag luam thiab qib siab ntawm cov teb chaws txawv teb chaws. Yuav kom daws tau cov teeb meem saum toj no, tsis yog lub dag zog ntawm kev sib tsoo hluav taws xob, tab sis kev txhawb nqa lwm cov kev txhawb nqa.
Raws li Tuam Tshoj txoj kev tawg tshuab hluav taws xob cov tuam txhab tsim hluav taws xob ntau ntau thiab ntau dua rau cov khoom siv, kev tswj nruj, qhov zoo ntawm cov khoom tawg hluav taws xob tseem zoo dua qub, txhim kho txoj kev txhim kho ceev ntawm kev nyab xeeb ntawm cov mines thiab petrochemical industries. Lub ntsiab tshwm sim yog tias pawg neeg tuag thiab pawg neeg raug xwm txheej tau raug txo kom tsawg, thiab qhov teeb meem kev ruaj ntseg tseem raug tsim los ntawm kev ua zoo.
