Dab tsi yog qhov ua haujlwm ntawm cov khoom siv roj sib xyaw?
Tam sim no, nyob rau hauv kev lag luam gas detector, muaj ntau yam gas detectors, ob qho tib si gases thiab tsis tshua muaj gases, nrog rau ntau yam gas detectors los ntes lawv. Thaum nws yog ib qho tsim nyog los kuaj xyuas ntau yam roj av, nws yog ib qho teeb meem tshwj xeeb los nqa ntau yam khoom siv tshawb nrhiav. Nyob rau hauv cov ntaub ntawv no, lub composite gas ntes tau los ua. Lub tshuab ntsuas roj sib xyaw tuaj yeem ntes tau ntau yam roj av, xws li plaub-hauv-ib thiab tsib-hauv-ib. Yog li dab tsi yog lub luag haujlwm ntawm cov khoom siv roj av?
Kev ua haujlwm ntawm compound gas detector:
1, nrhiav kom pom cov roj concentration:
Ib qho tseem ceeb heev ntawm kev siv lub compound gas detector yog los xyuas cov roj concentration. Nws tuaj yeem siv tau txhua lub sijhawm, thiab tuaj yeem tshawb xyuas cov roj hauv ib puag ncig kom kuaj tau zoo thiab nrawm ntawm lub sijhawm tiag tiag, thiab tso saib pom cov roj concentration ntawm cov tshuaj ntsuam xyuas ntawm cov cuab yeej, uas yooj yim rau cov neeg ua haujlwm tshawb xyuas lub sijhawm. . Ntxiv mus, nws kuj muaj lub luag haujlwm ntawm kev ceeb toom kev vibration, uas tuaj yeem suav tias yog triple lav ntawm qhov ntsuas.
2. Kev ceeb toom ceeb toom:
Hauv qee qhov chaw txwv nrog thaj chaw loj thiab ib puag ncig nyuaj, qhov chaw ua haujlwm tuaj yeem hais tau hloov pauv sai. Thaum lub concentration ntawm cov pa phem nyob rau hauv qhov chaw ua hauj lwm hloov, lub composite gas detector hnav los ntawm cov neeg ua hauj lwm yuav xa tawm ci acousto-optic tswb ceeb toom, flashing teeb thiab buzzing tswb suab, uas yuav nco ntsoov cov khub kom ceev faj nyob rau hauv lub sij hawm, thiab kuj. qhia rau lawv paub ib leeg txoj haujlwm thiab kev nyob deb, thiab tseem tuaj yeem qhia rau cov neeg ua haujlwm sab nraum qhov chaw txwv raws sijhawm.
3, yooj yim nqa:
Ntxiv rau qhov kev sim, cov khoom siv hluav taws xob sib xyaw kuj tseem ua raws li cov cai ntawm cov neeg ua haujlwm hauv thaj chaw ntawm ib qho cuab yeej, uas yooj yim rau cov neeg ua haujlwm nqa thiab txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm ntawm qhov tod tes.
