Our concentrate on is always to consolidate and enhance the excellent and service of tam solutions, in the meantime nquag tsim cov khoom tshiab kom tau raws li cov neeg siv khoom tshwj xeeb 'xav tau rau High Quality Underground Valve Well Gas Detector, Peb sov siab txais tos koj cov kev koom tes nyob rau hauv kev sib nrig sib ntxiv cov txiaj ntsig hauv nyob ze rau yav tom ntej.
Peb lub hom phiaj yog ib txwm sib sau ua ke thiab txhim kho qhov zoo tshaj plaws thiab kev pabcuam ntawm cov kev daws teeb meem tam sim no, nyob rau lub sijhawm no niaj hnub tsim cov khoom tshiab kom tau raws li cov neeg siv khoom tshwj xeeb xav tau.zoo gas kev nyab xeeb, Peb lub hom phiaj yog "los muab cov khoom lag luam thawj zaug thiab cov kev daws teeb meem thiab cov kev pabcuam zoo tshaj plaws rau peb cov neeg siv khoom, yog li peb tau paub tseeb tias koj yuav tsum muaj cov txiaj ntsig zoo los ntawm kev koom tes nrog peb". Yog tias koj txaus siab rau ib qho ntawm peb cov khoom lossis xav tham txog kev txiav txim siab, nco ntsoov tiv tauj peb. Peb tab tom nrhiav rau pem hauv ntej los tsim kev lag luam kev sib raug zoo nrog cov neeg siv khoom tshiab thoob ntiaj teb nyob rau yav tom ntej.
Nyob rau hauv cov txheej txheem ntawm kev siv cov roj av, 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 cov roj valve qhov dej. Gas valve qhov dej tuaj yeem ua rau cov pa paug vim cov khoom siv laus, 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.
1) Siv cov khoom siv laser siab heev (tunable laser spectroscopy (TDLAS) thev naus laus zis) nrog lub tswb tsis muaj tseeb thiab lub neej kev pab cuam txog li 5-10 xyoo;
2) Txais NB-IoT kev sib txuas lus thiab koom tes nrog cov neeg ua haujlwm tseem ceeb xws li Tuam Tshoj txawb xov tooj thiab kev sib txuas lus kom ntseeg tau kev sib txuas lus zoo;
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.
1) Roj teeb muaj peev xwm loj (152Ah) ntawm cov khoom lag luam thawj kab, txhim khu kev qha;
2) Siv cov cuab yeej laser siab tshaj plaws (tunable laser spectroscopy (TDLAS)) thev naus laus zis, nrog kev ntseeg siab, muaj peev xwm tiv thaiv kev cuam tshuam, tsis tshua muaj suab nrov thiab kev saib xyuas dawb;
3) Txais yuav NB-IOT wireless chaw taws teeb tswj kev daws teeb meem, kev siv hluav taws xob tsawg, kev pabcuam dav thiab muaj 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.
