Tsau combustible gas detector ntau yam
Nyob rau hauv niaj hnub kev lag luam thiab pej xeem teb, qhov teeb meem ntawm combustible gas leakage yeej ib txwm muaj kev txhawj xeeb loj. Kev xau ntawm cov roj hluav taws xob tsis yog tsuas yog ua rau muaj kev nyab xeeb, tab sis kuj muaj kev cuam tshuam loj rau tib neeg kev noj qab haus huv thiab ib puag ncig. Yog li ntawd, kev txhim kho cov khoom siv hluav taws xob hluav taws xob tau dhau los ua ib qho kev ntsuas tsim nyog rau ntau qhov chaw ua haujlwm thiab pej xeem. Ib tug zoo combustible gas detector tsis tau tsuas yog yuav tsum tau kom raug ntsuas cov pa concentration, tab sis kuj muaj ib tug dav nrhiav kom paub txog kev nyab xeeb.
Lub combustible gas detector yog ib yam khoom siv los saib xyuas qhov concentration ntawm combustible gases nyob rau hauv tsev thiab sab nraum zoov ib puag ncig. Nws feem ntau muaj cov sensors, controllers, thiab tso saib cov ntxaij vab tshaus. Lub sensor yog lub hauv paus tseem ceeb ntawm lub ntes, lub luag hauj lwm rau kev kuaj xyuas cov concentration ntawm combustible gases nyob rau hauv cov huab cua thiab hloov mus rau hauv hluav taws xob signals, uas yog ces kis mus rau lub maub los rau kev ua. Tus maub los yog lub luag haujlwm rau kev tshuaj xyuas cov teeb liab kis tau los ntawm cov sensors thiab ua rau lub suab nrov thiab lub teeb ceeb toom lossis tswj hwm lwm yam khoom siv kev nyab xeeb raws li lub tswb ceeb toom. Lub vijtsam zaub feem ntau qhia txog tus nqi roj concentration tam sim no thiab lwm yam ntaub ntawv ntsig txog.
Kev tshawb nrhiav ntau yam ntawm cov khoom siv hluav taws xob ruaj khov feem ntau sib txawv raws li qhov sib txawv ntawm daim ntawv thov scenarios thiab yuav tsum tau ua. Rau qee qhov chaw muaj kev pheej hmoo siab, xws li cov nroj tsuag tshuaj thiab cov chaw tso roj, nws yuav tsum muaj lub tshuab kuaj xyuas kom pom qhov dav dav los xyuas kom meej lub sijhawm ceeb toom. Rau qee qhov chaw muaj kev pheej hmoo tsawg, xws li tsev, tsev kawm ntawv, thiab lwm yam, ib qho kev kuaj pom qhov nqaim kuj tuaj yeem ua tau raws li qhov xav tau.
Kev tshawb nrhiav ntau yam ntawm cov khoom siv hluav taws xob uas muaj hluav taws xob feem ntau suav nrog tab sis tsis txwv rau cov hom roj hauv qab no:
1. Methane (natural gas): Methane yog cov roj uas muaj roj ntau, siv dav hauv qhov chaw xws li lub qhov cub roj, boilers, thiab qhov cub. Kev soj ntsuam methane tuaj yeem tiv thaiv kev sib tsoo zoo xws li cov pa xau thiab tawg.
2. Propane (liquefied petroleum gas): Propane yog hom roj liquefied roj av ntau heev, dav siv hauv teb xws li barbecue, cua sov, thiab dej kub. Kev kuaj pom ntawm propane tuaj yeem kuaj xyuas cov xau thaum ntxov kom tsis txhob muaj kev pheej hmoo ntawm kev nyab xeeb.
3. Acetylene: Acetylene yog cov roj siv dav siv hauv cov txheej txheem xws li hlau txiav thiab vuam. Kev soj ntsuam cov concentration ntawm acetylene tuaj yeem pab tswj kev nyab xeeb ntawm chaw ua haujlwm thiab tiv thaiv qhov tshwm sim ntawm hluav taws kub thiab tawg.
4. Cov pa roj carbon monoxide: Cov pa roj carbon monoxide yog cov roj uas tsis muaj xim, tsis muaj ntxhiab, thiab cov pa roj carbon monoxide uas yog cov khoom siv hluav taws xob tsis tiav. Kev saib xyuas raws sijhawm ntawm cov pa roj carbon monoxide concentration yog qhov tseem ceeb rau kev tiv thaiv tib neeg txoj kev nyab xeeb.
Ntxiv nrog rau cov khoom siv hluav taws xob uas tau hais los saum no, qhov kev tshawb nrhiav ntau yam ntawm cov khoom siv hluav taws xob ruaj khov tuaj yeem raug kho raws li kev xav tau. Piv txwv li, raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom, cov cuab yeej tshwj xeeb tuaj yeem txuas ntxiv txhawm rau txheeb xyuas lwm cov roj hluav taws xob, xws li hydrogen, ethanol, benzene, thiab formaldehyde.
Kev tshawb nrhiav ntau yam ntawm cov khoom siv hluav taws xob ruaj khov txiav txim siab nws qhov kev siv tau thiab kev ntseeg tau hauv cov xwm txheej sib txawv. Xaiv cov khoom siv hluav taws xob uas tsim nyog yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm tib neeg lub neej thiab khoom. Yog li ntawd, thaum yuav khoom thiab txhim kho cov khoom siv hluav taws xob hluav taws xob, nws yog ib qho tsim nyog yuav tsum ua tib zoo nkag siab txog ntau yam kev tshawb nrhiav thiab kev ua tau zoo ntawm cov khoom sib txawv, thiab xaiv raws li qhov xav tau tiag tiag.
