Lub hauv paus ntsiab lus calibration ntawm methane gas detector yog dab tsi?
Lub tshuab ntsuas roj methane feem ntau yog siv los ntsuas cov ntsiab lus methane thiab tuaj yeem tshawb xyuas qhov concentration ntawm methane nyob rau hauv qhov chaw ua haujlwm ntawm cov nplaim hluav taws kub thiab cov roj sib tov sib xyaw. Nws yog dav siv hauv kev lag luam xws li thee mining, roj av, thiab tshuaj lom neeg. Vim nws daim ntawv thov dav, nws tau lees paub los ntawm ntau lub tuam txhab ua ib qho tseem ceeb ntawm kev tsim khoom. Hauv kev siv cov methane gas detectors, calibration cov hauv paus ntsiab lus yog ib qho uas peb yuav tsum muab qhov tseem ceeb rau. Koj puas paub txoj cai calibration rau methane gas detectors?
Lub hauv paus ntsiab lus ntawm calibration ntawm methane gas detector yuav tsum siv cov qauv roj uas tau ntawv pov thawj los ntawm metrology thiab sib tw cov roj kuaj pom. Ua ntej, ua ntej calibrating lub methane gas detector, peb yuav tsum xyuas kom meej tias ib puag ncig ntawm lub combustible gas detector yog dawb ntawm combustible gases. Yog tias muaj cov pa roj combustible, lub hau los nag yuav tsum tau muab tshem tawm ua ntej, thiab qee qhov huab cua huv yuav tsum tau ntim ua ntej txuas ntxiv qhia cov qauv roj kom ntseeg tau qhov tseeb ntawm qhov tseeb.
Thaum cov roj kuaj sim yog sib xyaw ntawm hydrocarbons, isobutane yog cov qauv roj, ua raws li propane. Rau cov hydrocarbon sib xyaw nrog cov cua kub sib txawv uas tshwm sim thaum lub sij hawm combustion ntawm cov uas tsis yog hydrocarbon sib tov los yog cov pa roj uas muaj qhov txwv tsis pub tawg, yooj yim muaj thiab ruaj khov ib qho khoom siv roj xws li butane, isobutane, propane, thiab lwm yam. Nyob rau ntawm no, qhov ntau ntawm lub tswb yuav tsum tau kho raws li ib qho kev kuaj pom lub teeb liab kev sib raug zoo. Qhov no tseem txiav txim siab tias cov khoom siv roj methane yog cov khoom tsim nyog rau kev tsim khoom lag luam.
Thib ob, lub tshuab ntsuas roj methane no tau siv dav hauv ib puag ncig lossis cov mines uas muaj methane lossis thee hmoov av tawg. Cov neeg ua haujlwm siv nws los ntsuas cov ntsiab lus methane, thiab kev ua haujlwm yooj yim thiab yooj yim. Thaum lub ntsuas roj methane nyob rau hauv ib puag ncig kev lag luam pom tias cov methane concentration nce mus txog qhov tseem ceeb, nws yuav muab lub tswb ceeb toom los xyuas kom meej tias muaj kev ruaj ntseg, kev nyab xeeb khoom, thiab kev nyab xeeb ntawm cov neeg ua haujlwm. Yog li ntawd, nws tuaj yeem pom tias lub ntsuas roj methane yog cov khoom tsim nyog rau kev lag luam, thiab cov tuam txhab lag luam yuav tsum npaj ib qho los tiv thaiv kev phom sij.
