Tawg li cas?
Qhov tsim nyog ua rau kev tawg yog tias cov khoom siv tawg yuav tsum sib tov nrog oxygen hauv qee qhov sib npaug thiab ua rau muaj tshuaj lom neeg raws li cov roj taws tsim nyog. Nws yuav muab txhais Txhaum yog qhov tshuaj tiv thaiv nrawm tshaj suab tshaj tawm.
Thaum sib tov sib xyaw dhia mus txog ib qhov twg. nws yuav tawg nthe thiab ua rau muaj kev cuam tshuam rau hauv daim ntawv ntawm nthwv dej loj.
Dab tsi yog Anti-Tawg?
Kev tiv thaiv tuaj yeem tiv thaiv tau yog tias ib tus neeg ntawm peb qhov xwm txheej hais los saud yog raug txwv kom tshwm sim. Hauv ntau qhov chaw ua haujlwm, cov khoom siv tawg thiab pa oxygen yog qhov nyuaj rau zam, yog li cov pa taws yuav tsum tau txwv.
Cov khoom siv hluav taws xob yog qhov muaj peev xwm tiv tau qhov hluav taws xob, qhov no ua rau lub tsa hluav taws xob kom sov, ESD lossis hluav taws xob tshwm sim los ntawm qhov hloov hluav taws xob, thiab lwm yam thaum lub tshuab tig.
Cov khoom siv hluav taws xob los tiv thaiv tsis ua kom muaj qhov chaw tsis raug. vim tias nws zam dhau ntawm qhov chaw siab kub thiab hluav taws xob los ntawm qhov tam sim no nyob rau hauv cov txheej txheem hauv qhov tsim.
Kev faib tawm los ntawm cov chaw muaj peev xwm tuaj yeem tawg
Cov khoom siv hluav taws xob siv nyob rau hauv cov pa tawg txaus feem ntau muab faib ua ob pawg:
I. Cov khoom siv hluav taws xob tsim rau colliery;
II. cov cuab yeej hluav taws xob tsim rau lwm cov pa tawg pa tshwj xeeb tsuas yog ua kom tawg.
Rau cov cuab yeej hluav taws xob II, nws muaj peev xwm raug faib ua peb qhov loj ntawm qhov tawg ntawm II A, II B, II C raws li MESG (Exd) thiab qhov tsawg kawg yog qhov kev sim tam sim no (qhov kev nyab xeeb kev nyab xeeb) ntawm cov pa roj. thiab cov cuab yeej II B yog tsim rau kev pabcuam kev ua haujlwm ntawm khoom siv II A, cov khoom siv II C haum rau kev pabcuam cov haujlwm ntawm khoom siv II A thiab II B
Rau cov cuab yeej hluav taws xob ll, nws muaj peev xwm raug faib ua 6 pawg kub ntawm T1 (450 ° C), T2 (300 ° C), T3 (200 ° C), T4 (135 ° C), T5 (100 ° C), T6 (85 ° C) raws li kev pom zoo siab siab tshaj plaws saum npoo av, thiab cov cuab yeej ntawm siab dua pab pawg kub yog qhov tsim nyog rau cov kev pabcuam ntawm cov pawg kub qis dua.
Ntau tshaj li 90% cov roj tawg yog suav nrog qhov loj ntawm kev tawg ntawm II A, II B thiab pawg kub ntawm T1-T4.

Yuav ua li cas ua Anti-tawg?
Muaj ntau txoj kev sib txawv los ua cov khoom siv hluav taws xob kom haum rau qhov chaw tawg, muaj cov lus qhia ntxaws ntxaws ntawm cov kev no hauv cov qauv GB3836, IEC60079, EN50014, thiab lwm yam.
DCL anti-blast series hluav taws xob actuator yog tsim tawm ua ib hom Exd thiab ntais ntawv raws li cov qauv ntawm qhov qauv-GB3836.1-2010, GB3836.2-2010.
Ex
Exd actuator tso cai rau sab hauv qhov tawg, nplaim hluav taws kev sib koom ua ke yog tsim los tiv thaiv kev tiv thaiv sab hauv cov nplaim taws lossis cov nqa khoom tawg nthe nrog sab nraud. Kev tsim nyog rau kev sib koom ua ke nplaim hluav taws xob thiab qhov tsim nyog dav dav ntawm qhov sib koom ua ke tuaj yeem paub qhov no. Tib lub sijhawm, ib lub pob tawv tawv tawv tuaj yeem tiv taus lub siab qhov cuam tshuam los ntawm sab hauv qhov tawg yam tsis muaj kev puas ntsoog.
Cov khoom sib txuas hauv qab no ntawm DCL anti-blast series actuator tau tsim thiab tsim los ntawm tus qauv ntawm Exd.

Yuav ua li cas siv thiab tswj cov cuab yeej ntawm Anti-Tawg?
Kev ua haujlwm xws li kev teeb tsa, kev hloov kho, tu, kho thiab hloov yuav tsum tau ua los ntawm kev cob qhia thiab tsim nyog tawg-pov thawj cov kws tshaj lij kev ua haujlwm thiab yuav tsum ua kom nruj raws li [Cov Lus Qhia Ua Haujlwm] ntawm cov khoom siv hluav taws xob.
