Dab tsi yog qhov txawv ntawm combustible gas detector thiab toxic gas detector?
Lub combustible gas detector yog ib tug detector uas teb rau cov concentration ntawm ib los yog ntau combustible gases. Combustible gas detector muaj ob hom: catalytic hom thiab infrared optical hom. Thaum cov roj combustible nkag mus rau hauv lub ntes, nws ua rau oxidation cov tshuaj tiv thaiv (flameless combustion) nyob rau saum npoo ntawm platinum hlau, thiab lub tshav kub generated los ntawm nws nce lub kub ntawm platinum hlau, thiab cov resistivity ntawm platinum hlau hloov.
Cov khoom siv tshuaj lom neeg tuaj yeem siv los txheeb xyuas qhov concentration ntawm cov pa roj carbon monoxide hauv cov roj av, tshuaj thiab tshuaj hauv lub sijhawm tiag tiag los xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm! Lub tshuab kuaj xyuas roj toxic yog ib qho tsis cuam tshuam "ntse" detector, thiab cov hom roj toxic uas tuaj yeem ntes tau los ntawm lub tshuab ntes no thiab qhov dav ntawm kev tshawb nrhiav ntau yam yog qhov thib ob tsis muaj nyob hauv kev lag luam.
Cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv tshuaj lom neeg yog cov cuab yeej siv hauv cov chaw ua lag luam, thiab ntau tus neeg tsis paub qhov txawv ntawm lawv. Kab lus hauv qab no yuav qhia koj txog nws:
1, nrhiav kom tau roj
Lub combustible gas detector feem ntau kuaj cov roj combustible, thiab siv methane raws li tus qauv los xyuas qhov concentration ntawm combustible gas. Raws li qhov sib txawv flammable gases nyob rau hauv tus neeg siv qhov chaw ntawm kev siv, nws yuav tsum tau teem raws li nws lub ntsiab gases raws li tus qauv nrhiav kom tau roj concentration.
Lub tshuab kuaj xyuas cov pa tshuaj lom yuav tsum paub tias ib lossis ntau cov pa roj los kuaj xyuas tshwj xeeb. Koj tuaj yeem xaiv lub tswb ntsuas hluav taws xob ib leeg lossis lub ntsuas hluav taws xob sib xyaw ua ke, nyob ntawm seb puas muaj cov pa phem hauv qhov chaw siv yuav tsum tau kuaj pom ib leeg lossis ntau lub gases yuav tsum tau kuaj.
2. Gas sensor
Cov khoom siv hluav taws xob siv hluav taws xob siv hluav taws xob catalytic combustion gas sensor, thaum lub tshuab hluav taws xob muaj kuab paug siv electrochemical sensor, infrared sensor lossis PID sensor, thiab lwm yam., thiab chav ntsuas cov ntsiab lus ntawm cov roj kuaj pom txawv, uas yuav tsum muaj cov qauv kev hloov pauv.
