Cov khoom siv hluav taws xob muaj kuab lom, cov lus tshaj lij no suab tsis paub meej, thiab nws tsis tuaj yeem siv tau hauv lub neej zoo tib yam, yog li peb paub me ntsis txog qhov kev paub no, tab sis hauv qee qhov kev lag luam tshwj xeeb, cov cuab yeej zoo li no yuav tsum tau ua haujlwm.Muab lub luag haujlwm, cia peb taug kev mus rau hauv lub ntiaj teb no txawv ntawm cov npe thiab kawm qee qhov kev paub txog kev nyab xeeb.
Toxic Gas Detector - Siv los txheeb xyuas cov pa roj carbon monoxide (ppm) hauv qhov chaw ib puag ncig.Cov pa roj xws li carbon monoxide, hydrogen sulfide thiab hydrogen tuaj yeem kuaj pom.Cov khoom siv tshuaj lom neeg tau muab faib ua cov khoom siv tshuaj lom neeg muaj kev nyab xeeb thiab cov khoom siv hluav taws xob tsis zoo.Intrinsically muaj kev nyab xeeb cov khoom yog cov khoom muaj kev nyab xeeb intrinsically uas tuaj yeem siv rau hauv cov xwm txheej txaus ntshai heev.
Nta: 0, 2, 4 ~ 20, 22mA tam sim no tso zis / Modbus tsheb npav teeb liab;tsis siv neeg tiv thaiv muaj nuj nqi tiv thaiv high-concentration gas shock;high-precision, anti-poisoning imported sensor;ob cable inlets, yooj yim rau kev teeb tsa ntawm qhov chaw;ywj siab gas Chamber Cov qauv thiab sensor yog yooj yim los hloov;ib txheej programmable linkage tso zis interfaces;tsis siv neeg xoom taug qab thiab them nyiaj kub;Cov ntaub ntawv pov thawj tawg yog ExdⅡCT6.
Lub hauv paus ntsiab lus ua haujlwm: Lub ntsuas hluav taws xob / tshuaj lom neeg kuaj xyuas cov teeb liab hluav taws xob ntawm lub ntsuas hluav taws xob, thiab tom qab ua cov ntaub ntawv sab hauv, tso tawm 4-20mA tam sim no teeb liab lossis Modbus lub teeb liab sib thooj rau cov pa roj ib puag ncig.
Cov pa roj carbon monoxide detectors hauv cov cuab yeej tua hluav taws feem ntau yog ntsia hauv cov tuam txhab petrochemical.Dab tsi yog qhov kev teeb tsa tshwj xeeb rau cov cuab yeej siv tshuaj lom neeg hauv "Code for Design of Flammable Gas and Toxic Gas Detection and Alarm in Petrochemical Enterprises" uas tau teev tseg los ntawm lub xeev cov koom haum?Cov txheej txheem kev teeb tsa rau cov cuab yeej siv tshuaj lom neeg muaj npe hauv qab no los muab cov lus qhia rau txhua tus neeg los nruab cov khoom siv tshuaj lom neeg.
SH3063-1999 "Petrochemical Enterprises Combustible Gas thiab Toxic Gas Detection Alarm Design Specification" taw qhia:
1) Cov cuab yeej siv tshuaj lom neeg yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj kev cuam tshuam, kev co, thiab muaj zog electromagnetic teb cuam tshuam, thiab kev tshem tawm tsis pub tsawg dua 0.3m yuav tsum tau nyob ib puag ncig.
2) Thaum kuaj pom cov pa phem thiab cov pa phem, lub tshuab ntes yuav tsum tau muab tso rau hauv 1m ntawm qhov tso tawm.
a.Thaum kuaj pom cov pa phem thiab cov pa phem sib zog dua li huab cua xws li H2 thiab NH3, lub tshuab hluav taws xob tshuaj lom yuav tsum tau teeb tsa saum toj ntawm qhov tso tawm.
b.Thaum kuaj pom cov pa phem thiab cov pa phem hnyav dua li huab cua xws li H2S, CL2, SO2, thiab lwm yam, cov khoom siv hluav taws xob tsis zoo yuav tsum tau teeb tsa hauv qab qhov tso tawm.
c.Thaum kuaj pom cov pa phem thiab cov pa phem xws li CO thiab O2 uas nws lub ntiajteb txawj nqus yog ze rau ntawm huab cua thiab yooj yim sib xyaw nrog huab cua, nws yuav tsum tau muab tso rau hauv qhov chaw uas yooj yim ua pa.
3) Kev teeb tsa thiab xaim hluav taws xob ntsuas hluav taws xob yuav tsum ua raws li cov kev cai cuam tshuam ntawm GB50058-92 "Code for Design of Electric Power for Explosion and Fire Hazardous Environments" ntxiv rau cov kev cai teev tseg los ntawm cov chaw tsim khoom.
Nyob rau hauv luv luv: lub installation ntawm cov pa phem detectors yuav tsum nyob rau hauv ib lub vojvoog ntawm 1 meter nyob ze ntawm qhov chaw uas xau xws li li qub, yeeb nkab interfaces, thiab cov roj qhov hluav taws xob, ze li sai tau, tab sis tsis txhob cuam tshuam rau kev ua hauj lwm ntawm lwm yam khoom, thiab sim kom tsis txhob muaj qhov kub thiab txias, ib puag ncig ntawm cov av noo thiab cov kev cuam tshuam sab nraud (xws li dej txaws, roj thiab muaj peev xwm ua kom puas tsuaj.) tib lub sijhawm, nws yuav tsum tau txiav txim siab rau kev kho kom yooj yim thiab calibration.
Ntxiv nrog rau kev xyuam xim rau kev teeb tsa kom raug thiab siv cov khoom siv tshuaj lom neeg, kev saib xyuas kev nyab xeeb ntawm lub tshuab kuj yog ib qho uas tsis tuaj yeem tsis quav ntsej.Cov khoom siv tua hluav taws muaj qee qhov kev ua neej, thiab tom qab siv lub sijhawm, yuav muaj teeb meem ntawm ib hom lossis lwm qhov, thiab tib yam yog qhov tseeb ntawm cov khoom siv tshuaj lom neeg.Tom qab kev teeb tsa lub ntsuas roj toxic, qee qhov kev ua txhaum cai yuav tshwm sim tom qab khiav mus rau lub sijhawm.Thaum ntsib qhov txhaum, koj tuaj yeem xa mus rau cov hauv qab no.
1. Thaum nyeem ntawv deviates ntau dhau los ntawm qhov tseeb, qhov ua rau tsis ua haujlwm yuav yog qhov kev hloov pauv ntawm qhov rhiab heev lossis tsis ua haujlwm ntawm lub sensor, thiab lub sensor tuaj yeem rov kho dua lossis hloov pauv.
2. Thaum lub ntsuas ntsuas tsis ua haujlwm, nws yuav yog cov xaim xoob lossis luv luv;lub sensor puas, xoob, luv Circuit Court lossis siab concentration, koj tuaj yeem tshawb xyuas cov xaim, hloov lub sensor lossis recalibrate.
3. Thaum qhov kev nyeem ntawv tsis ruaj khov, nws yuav yog vim huab cua cuam tshuam thaum lub sij hawm calibration, sensor tsis ua hauj lwm, los yog Circuit Court tsis ua hauj lwm.Koj tuaj yeem rov kho dua, hloov lub sensor, lossis xa rov qab mus rau lub tuam txhab kho.
4. Thaum cov zis tam sim no tshaj 25mA, qhov tam sim no cov zis hluav taws xob tsis raug, nws raug nquahu kom xa rov qab mus rau lub tuam txhab rau kev saib xyuas, thiab lwm yam kev ua txhaum kuj tuaj yeem xa rov qab mus rau lub tuam txhab rau kev kho.
