Gas detectors cais li cas?
Feem ntau muaj cov pa roj tso tawm hauv qee qhov chaw tshwj xeeb, xws li petrochemical, thee, metallurgy, tshuaj lom neeg kev lag luam, roj hauv nroog, kev saib xyuas ib puag ncig thiab lwm qhov chaw. Thiab qee qhov ntawm cov pa roj no yuav ua rau muaj kev phom sij, xws li nplaim taws, tawg lossis muaj kuab paug, tom qab ntawd koj yuav tsum siv lub ntsuas roj los kuaj xyuas lawv. Yog li cas gas detectors cais?
Classified los ntawm kev siv
1. Portable teeb meem roj ntes
Cov cuab yeej sib txuas cov sensors, ntsuas circuits, qhia, tswb, rechargeable roj teeb, cua twj, thiab lwm yam rau hauv ib lub vaj tse los ua ib qho khoom siv sib xyaw, me me thiab lub teeb, yooj yim nqa, twj tso kua mis nqus sampling, thiab tuaj yeem kuaj tau txhua lub sijhawm thiab nyob qhov twg. Lub hnab tshos ntsuas yog ib yam khoom siv tau yooj yim, feem ntau tsis muaj cua twj tso kua mis diffusion sampling, siv los ntawm cov roj teeb qhuav, thiab me me heev.
2. Tsau lub ntsuas roj teeb meem
Cov cuab yeej no yog tsau rau ntawm qhov chaw, tsis tu ncua thiab tuaj yeem kuaj pom cov pa phem sib xws (steam), cia li ceeb toom thaum cov pa phem tshaj qhov txwv, thiab qee qhov tuaj yeem tswj tau lub tshuab tso pa tawm, thiab lwm yam. Cov twj paj nruag ruaj khov tau muab faib ua ob hom: ib qho thiab cais-hom.
Integrated tsau teeb meem roj ntes: ib yam li portable instrument, qhov txawv yog hais tias nws yog ntsia rau ntawm qhov chaw, 220V AC fais fab mov, nruam tsis siv neeg nrhiav thiab tswb, feem ntau diffuse sampling.
Split-type fixed gas detector: lub sensor thiab teeb liab kis tau tus mob Circuit Court yog sib sau ua ke nyob rau hauv ib tug tawg-pov thawj vaj tse, feem ntau hu ua lub sojntsuam, ntsia rau ntawm qhov chaw (qhov chaw txaus ntshai); qhov thib ob suav nrog kev ua cov ntaub ntawv, cov khoom siv thib ob, lub tswb tswj thiab lub zog hluav taws xob, sib sau ua ke rau hauv Tus maub los, feem ntau hu ua cov cuab yeej thib ob, tau nruab rau hauv chav tswj (qhov chaw nyab xeeb). Kev sojntsuam diffusion sampling nrhiav kom tau, qhov ntsuas thib ob qhia lub tswb.
Muab faib raws li cov khoom ntsuas thiab ntsuas lub hauv paus ntsiab lus
1. Combustible gas detector (abbreviated as explosion detector, ib qho cuab yeej rau kev soj ntsuam ntau yam combustible gases)
2. Catalytic combustion combustible gas detector kom paub ntau yam combustible gases los yog vapors.
3. Electrochemical toxic gas detector tuaj yeem ntes CO, H2S, NO, NO2, CL2, HCN, NH3, PH3 thiab ntau yam tshuaj lom cov organic sib txuas.
4. Infrared combustible gas detector mus ntes ntau yam combustible gases (nyob ntawm seb lub filtering technology).
5. Semiconductor combustible gas detector tuaj yeem ntes ntau yam roj combustible.
6. Thermal conductance combustible gas meter, uas kuaj cov roj hydrogen uas nws thermal conductance txawv heev ntawm huab cua.
7. Toxic gas detector (hu ua tshuaj lom neeg detector, ib qho cuab yeej los ntes cov pa phem).
8. Photoionization toxic gas detector, kuaj cov organic thiab inorganic tebchaw nrog ionization muaj peev xwm tsawg dua 11.7eV.
9. Infrared toxic gas detector, ntes CO, CO2, thiab lwm yam.
10. Semiconductor poisonous gas detector, ntes CO, thiab lwm yam.
