Sib sib zog nqus hauv kuv li, lub ntsuas roj ntseeg tau yog tus saib xyuas ntawm cov miners lub neej. Qhov chaw mining yog qhov nyuaj thiab txaus ntshai, ua rau kev xaiv cov cuab yeej zoo yog qhov tseem ceeb. Yuav ua li cas xaiv lub mine gas detector?
Mine gas detectors ua haujlwm nyob rau hauv ib puag ncig tshwj xeeb thiab hnyav heev. Cov mines yog qhov chaw nyob ib puag ncig, uas muaj qhov thaiv kom muaj zog, qhov cua tsis zoo, thiab nyiam cov pa roj ntau ntxiv. Cov kev pheej hmoo loj muaj xws li oxygen deficiency, ntau dhau ntawm cov pa phem xws li hydrogen sulfide thiab carbon monoxide, thiab cov pa tawm ntawm cov pa taws. Lub cuab yeej yuav tsum muaj peev xwm ua haujlwm ruaj khov nyob rau hauv cov huab cua huab cua siab, cov plua plav siab, thiab muaj peev xwm tawg tau.
1.Thaum xaiv lub mine gas detector, thawj yam uas yuav tsum tau xav txog yog nws hom sensor thiab nrhiav kom tau muaj peev xwm.
Catalytic combustion sensors feem ntau yog siv rau combustible gases, xws li methane.
Electrochemical sensors yog tsim los kuaj xyuas cov pa oxygen thiab carbon monoxide.
Rau ib puag ncig mining, plaub-hauv-ib lossis tsib-hauv- ib qho khoom siv kuaj pom feem ntau pom zoo, muaj peev xwm soj ntsuam cov ntsuas tseem ceeb xws li oxygen, hydrogen sulfide, carbon monoxide, thiab cov pa roj carbon monoxide, ua tiav ntau{4}} ntsuas ntsuas.
2.Prioritize Sampling Methods thiab Kev Tiv Thaiv Kev Ua Haujlwm
Hauv cov chaw kaw xws li cov mines, cov qauv ntsuas ntawm qhov ntsuas yog qhov tseem ceeb. Lub twj tso kua mis- yuav tsum tau siv txoj kev nqus cov pa, nquag rho tawm cov roj los ntawm kev tsim- hauv cov twj tso kua mis los xyuas kom meej qhov ceev thiab meej ntawm cov pa xa tawm hauv qhov chaw nyuaj, tso cai rau kev ntsuas ua ntej - nkag.
Kev tiv thaiv qib thiab tawg -cov ntaub ntawv pov thawj tsim cuam tshuam ncaj qha rau kev ntseeg ntawm cov khoom siv. Mining detectors xav tau kev tiv thaiv siab (xws li IP65 lossis IP67) thiab tshwj xeeb tawg- cov ntawv pov thawj ua raws li cov qauv kev tsuas; qhov no yog qhov yuav tsum tau ua kom muaj kev nyab xeeb hauv av.
3.Master Key Siv thiab Kho Cov Ntsiab Lus
Thaum xaiv lub tshuab ntes, ntev - lub sij hawm yooj yim thiab tus nqi yuav tsum raug txiav txim siab.
Portability thiab Durability: Cov cuab yeej yuav tsum yog lub teeb yuag (qhov zoo tshaj qhov hnyav tsis pub tshaj 1 kg), ua los ntawm kev cuam tshuam - cov ntaub ntawv tiv taus, thiab muaj peev xwm txhawb kev ua haujlwm tsis tu ncua rau lub sijhawm ntev (lub roj teeb lub neej yuav tsum yog yam tsawg kawg 12 teev).
Tswb Function: Lub tswb nrov thiab pom qhov muag yuav tsum ntseeg tau; Lub tswb suab yuav tsum feem ntau tsis pub tsawg tshaj 80 dB, thiab lub teeb liab yuav tsum pom meej meej hauv qhov tsaus ntuj.
Kev tu tsis tu ncua: Feem ntau lub tshuab ntsuas roj yuav tsum tau xoom txhua hli- taw tes thiab ntau qhov ntsuas, thiab cov khoom siv hluav taws xob feem ntau xav tau kev hloov pauv txhua ob xyoos kom paub tseeb tias qhov tseeb.
4.Kev sib piv cov kev teeb tsa sib txawv
Mining gas detectors muaj ntau yam kev xaiv, feem ntau categorized raws li hauv qab no:
Ob-hauv-One Gas Detector: Feem ntau saib xyuas methane thiab oxygen. Cov yam ntxwv muaj xws li kev txav mus los (kwv yees li 180g) thiab lub roj teeb ntev (tshaj li 12 teev), feem ntau yog siv rau hauv cov thee mine ua haujlwm ntsej muag thiab txoj kev.
4 hauv 1 Gas Detector: Ib txhij saib xyuas methane, oxygen, carbon monoxide, thiab carbon dioxide. Nws ua rau tib lub sijhawm saib xyuas ntawm ntau qhov tsis sib xws, ua kom pom lub suab nrov thiab pom lub tswb, thiab tsim nyog rau ib puag ncig uas muaj kev pheej hmoo ntawm cov pa tawg thiab cov pa roj thiab cov pa tawm.
Tsib-hauv-Ib Nrho: Ntxiv rau plaub-hauv-ib qho kev teeb tsa, nws ntxiv kev soj ntsuam rau cov pa roj xws li hydrogen sulfide, muab kev pabcuam dav dav ntawm cov pa phem. Nws feem ntau siv lub twj tso kua mis- nqus cov qauv, ua rau nws haum rau ntau qhov chaw hauv kuv qhov chaw.
Thaum xaiv ib lub tshuab ntes, thov ua tib zoo xav txog cov kev pheej hmoo tshwj xeeb ntawm koj lub mine, cov kev cai tswj hwm, thiab kev siv nyiaj txiag, ua tib zoo saib tag nrho cov xwm txheej no los ua kom muaj kev nyab xeeb ntawm cov miners.
