Cov pa luam yeeb feem ntau yog siv los ntsuas cov pa luam yeeb. Lawv yog thawj zaug tsim los ceeb toom ntawm cov pa taws uas tsim los ntawm hluav taws thiab feem ntau tsis siv ncaj qha los ntsuas cov pa xau.
1. Txoj Cai Ua Haujlwm ntawm Cov Hluav Taws Xob Hluav Taws Xob
Cov pa luam yeeb yog MQ2 gas sensors raws li cov pa sensors, uas tuaj yeem ntes cov pa taws, cov pa roj liquefied, butane, propane, methane, cawv, hydrogen thiab lwm yam pa hauv huab cua. Txawm li cas los xij, qhov kev tshawb pom ntawm no yog qhov tseem ceeb rau kev tshawb nrhiav pom cov pa luam yeeb, tsis yog tshwj xeeb rau kev kuaj pom cov pa. Piv txwv li, thaum cov pa luam yeeb concentration nyob rau hauv cov huab cua mus txog ib theem, lub sensor nyob rau hauv lub pa taws detector yuav hnov, ua rau lub tswb. Nws tsuas yog ua haujlwm los ntawm kev hnov cov yam ntxwv kho qhov muag lossis ionization ntawm cov pa taws, uas txawv heev ntawm cov khoom siv tshwj xeeb uas pom cov pa paug hauv cov ntsiab lus ntawm kev tshawb pom lub hom phiaj thiab qhov tseeb.
2. Cov cuab yeej tshwj xeeb ntawm cov pa tawm kom pom
(I) Combustible gas detectors
1. Muaj peev xwm ntes tau ntau yam roj combustible
- Cov khoom siv hluav taws xob tuaj yeem ntes tau ntau yam roj av, xws li hydrogen, methane, ethane, propane, butane, nonane, methanol, ethanol, propanol, ethylene, ethyl acetate, toluene, xylene, acetone, butanone, vinyl chloride, liquefied gas. , acetylene, acrylonitrile, methane, cyclohexane, propylene, dimethylamine, acetic acid, formaldehyde, diesel, roj av, acetic acid, ethanol, hnyav roj, ethylene oxide, dimethyl sulfate, sulfur hexafluoride, methyl ether, methyl ether, roj thiab roj thiab lwm yam combustible gases.
- Cov khoom siv hluav taws xob sib txuas no hloov cov pa hluav taws xob nqus cov teeb liab mus rau hauv lub teeb liab hluav taws xob los ntawm lub sensor, thiab tom qab ntawd xa cov lej teeb liab mus rau lub vijtsam zaub tom qab lub microcomputer ib leeg tau txais cov teeb liab voltage thiab ua cov ntaub ntawv. Thaum cov roj combustible concentration ntau tshaj qhov teeb tsa lub tswb, lub tswb yuav suab thiab lub teeb tswb, thiab tseem tuaj yeem txuas nrog cov khoom siv sab nraud los txuas cov kiv cua, solenoid li qub thiab lwm yam khoom siv.
2. Cov chaw thov dav
- Cov khoom siv hluav taws xob hluav taws xob tau siv dav hauv petrochemical, kev tsim khoom lag luam, smelting thiab forging, hluav taws xob, thee mining, tunnel engineering, kev saib xyuas ib puag ncig, dej phwj tuaj, biopharmaceuticals, kev tiv thaiv tsev neeg ib puag ncig, tsiaj txhu, cog tsev cog khoom, warehousing thiab logistics, brewing thiab fermentation , kev tsim khoom ua liaj ua teb thiab kev tiv thaiv hluav taws, roj, kev tsim kho, kev lag luam hauv nroog, tsev kawm ntawv lub chaw soj nstuam, cov chaw tshawb fawb tshawb fawb thiab lwm qhov chaw.
(II) Leak detector (xws li hydrocarbon gas GasenaminiGS-20)
- Siv cov pa roj carbon monoxide GasenaminiGS-20 ua piv txwv, nws yog ib qho khoom siv raug thiab muaj txiaj ntsig zoo nrog kev ntsuas LED thiab lub tswb nrov, uas tuaj yeem saib xyuas cov roj hydrocarbon roj los ntawm cov kav dej lossis lwm yam khoom siv, xws li methane, propane. .
3. Cov lus xaus
Txawm hais tias cov khoom siv hluav taws xob tuaj yeem muaj peev xwm nkag siab qee yam roj av, lawv tsis tuaj yeem siv los ua cov khoom siv hluav taws xob kom pom tseeb vim tias lawv txoj haujlwm yog txhawm rau kuaj cov pa taws. Nyob rau hauv cov xwm txheej uas yuav tsum tau kuaj xyuas cov pa xau, cov khoom siv hluav taws xob uas muaj hluav taws xob, cov khoom siv hluav taws xob thiab lwm yam khoom siv yuav tsum tau siv los xyuas kom meej qhov tseeb thiab ceeb toom raws sijhawm ntawm cov pa xau.
