Lub tshuab pa yog ib hom roj txhawm rau tshawb nrhiav kom paub lub zog, feem ntau hais txog kev siv lub tshuab pa thiab lub roj ntsuas pa.Gas cov ntsuas hluav taws xob yog siv los txhawm rau txhawm rau cov pa roj hauv qhov chaw ib puag ncig thiab txhawm rau txheeb xyuas qhov sib xyaw thiab cov ntsiab lus roj.
1ST, kev teeb tsa txheem 4in1 ntes roj ：
Qee tus neeg tsis meej txog tus txheej txheem plaub-hauv-ib qho roj thiab qee qhov pom ntawm roj. Qhov yooj yim hais lus, tus qauv plaub-hauv-ib qho roj suav nrog: kev sib txuas (cov pa roj) 0-100% LEL, cov pa roj carbon monoxide 0-1000ppm, oxygen 0-30% VOL, hydrogen sulfide 0-100ppm.
2ND, qhov sib txawv ntawm lub ntuj sib txawv thiab hom nqus dej:
Cov pa roj muaj ob txoj kev kuaj pom, ib qho yog hom diffusion, lwm qhov yog twj tso kua mis hom, Qhov sib txawv ntawm ob yog, hom diffusion tsis tawm ib qho kev quab yuam sab nraud hnov roj qeeb qeeb, twj tso kua mis yog qhov kev tshoov siab siv cov twj tso kua mis nws tus kheej, xws li raws li lub qhov ntswg ntawm cov lus teb tau nrawm dua, kom tau txais cov pa roj uas tib neeg tsis yooj yim nkag, yog li xaiv dab tsi los tsom cov tswv yim nrhiav kev, nrhiav kom pom cov roj kom zoo.
3RD. Qhov ntsuas kev tshuav ntawm nitrogen nrog cov pa ntsuas tau yog dab tsi?
Cov pa oxygen thiab nitrogen yog cov pa roj cua, thiab lub ntsiab ntawm huab cua yog cov pa oxygen 30% thiab nitrogen 70%. Vim tias tus nqi siab ntawm lub ntsuas tshwj xeeb rau nitrogen, qee cov neeg yuav xaiv siv lub pa oxygen ntsuas los ntsuas nitrogen rov qab, uas yog ua tau, hu ua 100 rho tawm cov ntsiab lus ntawm cov pa oxygen, uas yog cov ntsiab lus muaj txiaj ntsig ntawm oxygen.
4TH. Puas yog lub tshuab hluav taws xob tawg-pov thawj?
Txhawm rau saib seb lub tshuab hluav taws xob tawg yog pov thawj kev pov thawj. qhov dav tawg-pov thawj theem yog BT3, BT4, CT3, yog li peb yuav qhov kev kuaj pom los ntawm cov qib no tawg ntau-pov thawj.
Cov ntsuas roj tuaj yeem ntes cov tshuaj hydrogen sulfide, carbon monoxide, oxygen, oxygen, sulfur dioxide, phosphorus, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine dioxide, chlorine dioxide, chlorine dioxide thiab roj thiab lwm cov pa roj, dav siv hauv petrochemical, thee, metallurgy, kev lag luam tshuaj lom neeg , Kev siv roj hauv nroog, kev saib xyuas ib puag ncig thiab lwm qhov chaw hauv qhov chaw nrhiav kom tau.Yog paub qhov tshwj xeeb ntsuas kev xav tau; kev ntsuas roj lossis nrhiav kom tsis tuaj yeem tuaj yeem nqa tau hauv qhov av, qhov raj xa dej, lub raj xa dej, qhov chaw kaw, thiab lwm yam
