Distinguishing ntawm combustible thiab toxic gas detectors
Gas detectors muaj ntau yam kev siv nyob rau hauv kev lag luam teb ntawm Tuam Tshoj, thiab lawv daim ntawv thov tus nqi yog nce nqi thiab kev txhawj xeeb los ntawm cov neeg. Peb paub tias nyob rau hauv kev faib tawm ntawm cov roj detectors, muaj cov pa roj toxic detectors, combustible gas detectors, portable gas detectors, thiab fixed gas detectors. Koj puas paub qhov txawv ntawm combustible gas detectors thiab toxic gas detectors? Txhawm rau teb koj cov lus nug, Ousenjie yuav tam sim no muab cov lus qhia ntxaws ntxaws.
1. Kev kuaj pom roj
Lub combustible gas detector feem ntau kuaj cov roj combustible thiab siv methane raws li tus qauv los xyuas qhov concentration ntawm combustible gases. Raws li qhov sib txawv combustible gases nyob rau hauv tus neeg siv qhov chaw ntawm kev siv, cov roj concentration yuav tsum tau teem raws li lub ntsiab roj raws li tus qauv nrhiav kom tau roj.
Lub tshuab kuaj roj toxic yuav tsum paub seb cov roj tshwj xeeb lossis cov pa phem twg los kuaj xyuas. Koj tuaj yeem xaiv lub tswb ntsuas tshuaj lom neeg sib cais lossis cov khoom siv tshuaj lom tshuaj lom neeg sib xyaw, nyob ntawm seb cov pa tshuaj lom hauv thaj chaw siv yuav tsum tau kuaj pom rau ib qho roj lossis ntau cov pa roj.
2. Gas sensor
Lub combustible gas detector siv catalytic combustion gas sensors, thaum lub toxic gas detector siv electrochemical sensors, infrared sensors, los yog PID sensors. Chav tsev concentration cov ntsiab lus ntawm cov roj pom tau sib txawv, thiab cov qauv ntawm cov qauv yuav tsum tau hloov dua siab tshiab.
3. Cov ntsiab lus tseem ceeb
Lub tswb ntawm lub combustible gas detector txais lub catalytic combustion gas sensing lub caij, thaum lub tswb ntawm cov pa phem detector txais ib tug electrochemical toxic gas tswb txoj kev. Yog tias koj xav kuaj cov pa roj carbon monoxide, koj xav tau ib-rau-ib lub sensors vim tias cov pa roj carbon monoxide sib txawv txawv, xws li ammonia, chlorine, hydrogen sulfide, thiab lwm yam pa phem.
Yog tias kuaj pom cov roj hluav taws xob (flammable thiab explosive gases), lub sensor tuaj yeem yog universal, tab sis cov calibration coefficients rau txhua qhov roj sib txawv. Cov nplaim hluav taws sib txawv muaj cov khoom siv tshuaj sib txawv thiab txwv kev tawg.
