Kev tiv thaiv kev nyab xeeb ntawm lub tshuab ntes nplaim taws thiab pa luam yeeb
Kev Taw Qhia
Kev nyab xeeb thiab kev tiv thaiv hluav taws yog qhov tseem ceeb heev rau txhua qhov chaw. Lawv tseem ceeb heev rau hauv cov chaw muaj kev phom sij uas yuav muaj hluav taws thiab tawg. Hauv qhov no, Kev Nyab Xeeb Sab Hauv Cov cuab yeej ntes hluav taws thiab cov laj kab kev nyab xeeb sab hauv muaj txiaj ntsig zoo heev. Cov txheej txheem tshwj xeeb no tau tsim los tiv thaiv hluav taws thiab kev tawg. Lawv ua tiav qhov no los ntawm kev txo cov hluav taws xob thiab lub zog thermal hauv lub kaw lus ntes.
Cov ntsiab lus tseem ceeb:
nCov cuab yeej ntes hluav taws uas muaj kev nyab xeeb yog cov kev ntsuas kev nyab xeeb tseem ceeb hauv cov chaw muaj kev phom sij uas muaj cov pa roj tawg lossis cov khoom yooj yim hlawv.
nCov khoom siv tshwj xeeb no tshem tawm cov teeb meem kev kub hnyiab los ntawm kev txwv tsis pub siv hluav taws xob los ua kom sov.
nHauv cov teb uas muaj kev pheej hmoo siab xws li petrochemicals, kev tsim tshuaj, thiab kev khaws cia cov khoom phom sij, cov thev naus laus zis no tsis muaj qhov hloov pauv tau.
nKev paub txog cov yam ntxwv thiab cov xwm txheej siv tau ntawm ntau hom kev nyab xeeb ntawm lub cev yog qhov tseem ceeb hauv kev tsim kom muaj lub kaw lus tiv thaiv hluav taws kom raug.
nKev ua tau zoo ntawm kev nyab xeeb thiab kev ruaj khov ntawm cov khoom siv ntes tau ntawv pov thawj los ntawm cov koom haum thoob ntiaj teb xws li Atex tau raug lees paub ua ntej lawm.
Lub tshuab ntes hluav taws kub ua haujlwm li cas?
nHauv cov chaw uas yoo hluav taws thiab tawg xws li roj thiab roj av, tshuaj lom neeg, thiab kev ua cov nplej, cov khoom ntes hluav taws ib txwm muaj kev phom sij rau kev nyab xeeb vim muaj peev xwm ua rau muaj hluav taws xob lossis kub dhau ntawm qhov chaw, thaum cov khoom ntes kev nyab xeeb (IS) ua kom muaj kev nyab xeeb hauv cov chaw muaj kev phom sij los ntawm kev tsim tshwj xeeb.
nNws cov thev naus laus zis tseem ceeb yog nyob rau hauv lub tshuab txwv lub zog: los ntawm kev tswj hwm lub zog tam sim no thiab lub zog cua sov hauv lub voj voog, nws ua kom ntseeg tau tias cov khoom siv yuav tsis tsim cov hluav taws xob lossis qhov kub siab txaus ntshai nyob rau hauv txhua qhov xwm txheej ua haujlwm. Txhawm rau ua tiav lub hom phiaj no, lub kaw lus yuav tsum tau nruab nrog lub laj kab kev nyab xeeb - ib qho tseem ceeb ntsia nruab nrab ntawm lub tswb ceeb toom thiab cov khoom siv IS, uas tuaj yeem thaiv kev xa hluav taws xob ntau dhau thiab tswj lub zog ntawm lub voj voog hauv qab qhov kev nyab xeeb txhua lub sijhawm.
nQhov kev tsim kev tiv thaiv ob npaug no (kev txwv lub zog sab hauv + kev thaiv kev nyab xeeb sab nraud) ua rau IS detector yog qhov kev daws teeb meem saib xyuas hluav taws zoo tshaj plaws rau thaj chaw muaj kev pheej hmoo siab, thaum ua tau raws li cov qauv tiv thaiv kev tawg thoob ntiaj teb xws li ATEX.
Kev ua raws li thiab cov qauv ntawm cov khoom siv tua hluav taws kev nyab xeeb hauv UK
Nyob rau hauv UK, muaj cov cai nruj heev rau kev siv cov khoom siv hluav taws kub hauv thaj chaw muaj kev phom sij. Kev ua raws li cov cai no tsis yog tsuas yog qhov yuav tsum tau ua raws li txoj cai xwb, tab sis kuj tseem ceeb heev rau kev ua kom cov neeg ua haujlwm muaj kev nyab xeeb thiab kev ua haujlwm zoo.
Ib pawg tseem ceeb ntawm cov cai yog Cov Cai AtexCov cai no yog los ntawm EU cov lus qhia uas tsom mus rau kev sib koom tes cov qauv kev nyab xeeb rau cov khoom siv siv hauv thaj chaw uas yuav muaj kev tawg.
Cov cai ntawm ATEX yog qhov tseem ceeb rau txhua tus neeg uas tsim khoom, muag khoom, lossis siv cov khoom siv kev nyab xeeb hauv thaj chaw uas yuav muaj kev tawg. Hauv cov chaw txaus ntshai hauv European Union (suav nrog UK), txhua yam khoom siv thiab cov txheej txheem tiv thaiv yuav tsum ua raws li cov cai ntawm ATEX.
Tus Qauv | Kev piav qhia |
Cov Lus Qhia ATEX 2014/34/EU | Qhov no suav nrog cov khoom siv thiab cov txheej txheem tiv thaiv siv rau hauv cov chaw uas yuav muaj kev tawg. |
IEC 60079 | Ib pawg cai thoob ntiaj teb txog kev tsim qauv, teeb tsa, thiab siv cov khoom siv hluav taws xob kom muaj kev nyab xeeb hauv thaj chaw muaj kev tawg. |
Kev nkag siab thiab ua raws li cov cai no yog qhov tseem ceeb heev. Qhov no pab ua kom muaj kev nyab xeeb thaum siv cov khoom siv tua hluav taws uas muaj kev nyab xeeb hauv thaj chaw muaj kev phom sij.
Xaiv cov teeb meem kev nyab xeeb sab hauv uas tsim nyog
Peb, Beijing Pinghe, ua tus neeg muab khoom zoo ntawm cov teeb meem, muaj ib txoj kev npaj tsim kho uas tsom mus rau kev txo qhov loj ntawm cov teeb meem, ua rau lawv sib dua thiab yooj yim rau kev ua haujlwm, ua kom yooj yim rau kev teeb tsa, txo qhov kev pheej hmoo ntawm kev ua tsis tiav, thiab muab cov teeb meem uas haum rau cov txheej txheem txheej txheem.
Peb cov PHD-11TN-11 thiab PHD-22TN-1111 yog tsim los rau kev siv nrog cov tshuab ntes pa luam yeeb.
Cov teeb liab nkag ntawm cov khoom ntes nplaim taws thiab pa luam yeeb yog cov teeb meem kev nyab xeeb cais tawm, uas tuaj yeem muab lub zog cais tawm rau cov khoom ntes nplaim taws hauv thaj chaw muaj kev phom sij. Cov khoom ntes nplaim taws tsim cov teeb liab 0-40mA uas cais tawm ntawm thaj chaw muaj kev phom sij thiab xa mus rau thaj chaw muaj kev nyab xeeb, ua lub luag haujlwm hauv lub tswb ceeb toom pa luam yeeb. Cov khoom no siv hluav taws xob los ntawm lub voj voog tso zis thiab tsim nyog rau cov kab ke DCS / PLC uas siv hluav taws xob.
Cov khoom no tsis xav tau lub hwj chim ywj pheej, thiab cov qhov nkag thiab qhov tso zis raug cais tawm.
