Four-in-one gas detector fault detector
Lub tshuab hluav taws xob plaub-hauv-ib yog ib qho roj lossis ntau lub tshuab ntsuas roj uas tuaj yeem hloov kho tau yooj yim. Nws tuaj yeem nruab nrog lub ntsuas pa oxygen, lub tshuab hluav taws xob hluav taws xob hluav taws xob, lub tshuab hluav taws xob muaj kuab paug lossis ib qho plaub roj sensors lossis ib qho roj. sensor. Lub tshuab hluav taws xob plaub-hauv-ib muaj lub vijtsam LCD loj heev, rov qab teeb pom kev zoo, thiab hnov thiab pom kev vibration tswb ceeb toom, kom ntseeg tau tias cov pa phem tuaj yeem kuaj pom hauv qhov chaw ua haujlwm tsis zoo thiab ua rau cov neeg ua haujlwm ceev faj hauv lub sijhawm.
Lub hauv paus ntsiab lus ntawm kev tshawb nrhiav ib feem ntawm plaub-hauv-ib lub ntsuas roj yog tias thaum ntsuas cov pa roj carbon monoxide ntau tshaj qhov txwv tus nqi, qhov txuas txuas txuas txuas hluav taws xob thiab hluav taws xob ntsuas hluav taws xob teeb tsa hluav taws xob, los ntawm qhov sib piv qhov hluav taws xob, lub tshuab hluav taws xob square yoj outputs a teeb ntawm square wave generators. Wave signal, tswj lub suab, lub teeb pom kev hauv Circuit Court, lub buzzer ua suab nrov, lub teeb-emitting diode flashes, thiab xa tawm lub teeb liab nrhiav pom. Los ntawm lub hauv paus ntsiab lus ntawm plaub-nyob rau hauv-ib gas detector, nws yuav pom tau hais tias yog hais tias electromagnetic cuam tshuam tshwm sim, nws yuav cuam tshuam rau cov teeb liab ntes thiab ua rau cov ntaub ntawv sib txawv; yog tias muaj kev sib tsoo lossis kev vibration uas ua rau cov khoom siv tsis raug, kev tshawb nrhiav tsis ua haujlwm yuav tshwm sim; yog tias ib puag ncig ntub dhau los yog cov khoom siv muaj dej nkag, nws kuj yuav tshwm sim. Nws yuav ua rau luv luv Circuit Court nyob rau hauv plaub-hauv-ib gas detector, los yog tus nqi hluav taws xob tiv thaiv Circuit Court yuav hloov, ua rau pom tsis ua hauj lwm.
Formaldehyde yog xim tsis muaj xim, soluble, irritating gas. Man-made panels xws li particleboard, board ntom ntom, thiab plywood, adhesives thiab wallpaper yog lub ntsiab qhov chaw ntawm formaldehyde nyob rau hauv cov huab cua, nrog rau lub sij hawm tso tawm ntawm 3 mus rau 15 xyoo. Nws tuaj yeem nqus tau los ntawm kev ua pa. Kev puas tsuaj ntawm formaldehyde rau tib neeg lub cev yog tus cwj pwm los ntawm lub sijhawm ntev, latent thiab zais cov teebmeem. Kev nqus pa ntev ntev ntawm formaldehyde tuaj yeem ua rau muaj teeb meem kev nyab xeeb loj xws li mob qog noj ntshav nasopharyngeal thiab mob qog noj ntshav.
Piv txwv li: tom qab formaldehyde txuas nrog daim ntawv, cov reagent muaj nyob rau hauv daim ntawv yuav hnov mob nrog formaldehyde los ua ib tug compound, thiab xim yuav hloov ntawm dawb mus rau daj. Qhov degree ntawm discoloration qhia txog tus nqi ntawm lub teeb uas tau txais. Qhov kev siv zog hloov pauv ntawm qhov pom lub teeb npaum li cas tuaj yeem siv los ua cov lus teb rau cov roj concentration. Los ntawm kev teeb tsa lub calibration nkhaus ua ntej, qhov concentration ntawm cov roj tuaj yeem txiav txim siab raws li cov lus teb tus nqi ntawm cov pa yuav raug kuaj pom.
Lub tshuab hluav taws xob plaub-hauv-ib lub tshuab muaj ob ntu: kev tshawb nrhiav thiab kev tshawb nrhiav, thiab muaj kev tshawb nrhiav thiab kev ua haujlwm. Lub hauv paus ntsiab lus ntawm kev tshawb nrhiav ib feem ntawm plaub-hauv-ib lub tshuab hluav taws xob yog tias lub ntsuas hluav taws xob ntawm qhov ntsuas siv cov khoom tshawb nrhiav, ib qho kev ruaj khov thiab xoom-kho potentiometer los tsim ib tus choj nrhiav pom. Tus choj siv platinum hlau ua tus cab kuj los catalyze lub caij. Tom qab siv fais fab, qhov kub ntawm cov hlau platinum nce mus rau qhov kub thiab txias, thiab huab cua mus txog qhov chaw ntawm lub caij los ntawm ntuj diffusion los yog lwm txoj kev. Thaum tsis muaj cov pa hluav taws xob hauv huab cua, qhov tso tawm ntawm tus choj yog xoom. Thaum cov huab cua muaj cov pa roj tsw qab thiab diffuses rau cov khoom tshawb nrhiav, flameless combustion tshwm sim vim catalysis, uas ua rau kom qhov kub thiab txias ntawm cov khoom kuaj pom thiab ua rau kom cov platinum hlau tsis kam. , ua rau tus choj Circuit Court poob qis, yog li outputting voltage teeb liab. Qhov loj ntawm qhov hluav taws xob no yog proportional rau qhov concentration ntawm cov pa hluav taws xob. Lub teeb liab yog amplified, analog-to-digital hloov dua siab tshiab, thiab cov concentration ntawm cov roj flammable yog tso tawm rau ntawm cov kua zaub.
