DT-AEC2531 Combustible Gas Monitoring Device rau Underground Well Room
Keeb kwm
Nyob rau hauv tus txheej txheem ntawm kev sivnatural gas detector, ntau yam khoom siv thiab cov khoom siv xws li cov kav dej, qhov chaw nres tsheb, cov cuab yeej tswj kev siab, lub qhov dej valve, thiab lwm yam. Cov khoom siv roj nyuaj no thiab cov kav dej sib txuas tau coj ntau yam teeb meem rau kev tswj hwm ntawm cov tuam txhab roj, tshwj xeeb tshaj yog kev tswj hwm ntawmgas valvelub qhov dej. Gas valve qhov dej tuaj yeem ua raugas xauvim kev laus ntawm cov khoom siv, kev ua txhaum, thiab kev ua haujlwm tsis raug ntawm cov neeg ua haujlwm. Txawm li cas los xij, kev tshuaj xyuas phau ntawv ib txwm yog qhov nyuaj rau kev maj mus rau qhov chaw kom tau txais kev kho mob zoo nyob rau thawj zaug vim qhov kev soj ntsuam ceev thiab kev tshuaj ntsuam xyuas. Tag nrho cov no tau coj cov teeb meem rau kev tswj hwm cov tuam txhab roj.
Khoom zoo
1) Siv cov tshuab laser siab heev (tunable laser spectroscopy (TDLAS) technology) nrog lub tswb tsis muaj tseebthiab covkev pab cuam lub neej yog mus txog 5-10 xyoo;
2) Txais NB-IoT kev sib txuas lus thiab koom tes nrog cov neeg ua haujlwm tseem ceeb xws liTuam Tshojmobile thiab telecommunications kom ntseeg tau kev sib txuas lus;
3) Lub tshuab tag nrho yog tsim los nrog kev siv hluav taws xob tsawg thiab lub sijhawm ua haujlwm ntev, uas tuaj yeem txo cov nqi tu cov cuab yeej zoo.
Cov yam ntxwv tseem ceeb
1) Roj teeb muaj peev xwm loj(152 Aws)ntawm domestic thawj-kab hom, txhim khu kev qha muaj peev xwm;
2) Siv cov khoom siv laser siab heev (tunable laser spectroscopy (TDLAS) technology,cu high kev ntseeg siab, muaj zog tiv thaiv kev cuam tshuam muaj peev xwm, tsis muaj lub tswb tsis muaj tseeb thiab kev saib xyuas dawb;
3) Txais NB-IOT wireless chaw taws teeb kis tau tus mob kev daws teeb meem, kev siv hluav taws xob tsawg, kev pabcuam davthiabmuaj peev xwm txuas tau zoo;
4) Zoo npog lub tswb txawv txav thiab kev kho mob xwm txheej ceev kom tsis txhob muaj xwm txheej;
5) Lub tswb ceeb toom dej nyab tshawb pom cov khoom siv raws li txoj cai thiab qhia rau tus neeg siv tias cov khoom siv nyob rau hauv kev tshawb pom lub qhov rais khoob.

Mounting hom
6.1 Ntes installation hom:
Thaum twgkuaj pom cov pa roj combustiblenrog qhov hnyav tshwj xeeb tshaj li huab cua xws li methane, lub tshuab ntes yuav tsum tau muab ntsia kom ze rau ntawm lub taub dej li sai tau (qhov kev ncua deb ntawm lub taub dej yuav tsum tsis pub tshaj 30cm)
6.2 Manhole npog kev hloov pauv kev teeb tsa
Lub manhole npog hloov pauv hloov mus rau qhov chaw dav hlau hauv av, thiab sab saum toj ntawm lub manhole npog hloov pauv tus pas nrig yog ntau dua 2cm siab dua li lub hau npog manhole (raws li qhia hauv daim duab hauv qab no). Tom qab kev teeb tsa, qhov hloov pauv tuaj yeem tshwm sim thaum lub npog manhole raug kaw.
