Kev tawg tuaj yeem ua rau muaj kev hem thawj loj rau kev lag luam sib txawv uas cuam tshuam nrog cov khoom siv hluav taws xob lossis roj. Txhawm rau txo qhov kev pheej hmoo no, cov cuab yeej pov thawj tawg yog tsim thiab siv nyob rau hauv ntau qhov chaw txaus ntshai. Cov khoom siv no raug cais raws li lawv qib kev tiv thaiv tiv thaiv kev tawg. Hauv tsab xov xwm no, peb yuav tham txog qhov sib txawv ntawm cov khoom tawg-pov thawj.
Class I Explosion-Proof Equipment
Cov cuab yeej siv hauv chav kawm I yog tsim thiab siv rau hauv thaj chaw uas muaj cov pa taws thiab vapors tuaj yeem tshwm sim. Hom khoom siv no yuav tsum muaj peev xwm muaj peev xwm tawg tau hauv nws, tiv thaiv nws los ntawm kev nthuav tawm mus rau ib puag ncig ib puag ncig. Qee qhov piv txwv ntawm cov cuab yeej tawg-pov thawj Class I muaj xws li hluav taws xob motors, keyboards, thiab tswj cov khoom siv.
Class II Explosion-Proof Equipment
Cov cuab yeej siv hauv chav II yog siv rau hauv qhov chaw uas muaj cov plua plav uas tuaj yeem tshwm sim, xws li cov hmoov nplej, cov chaw npaj cov thee, lossis cov chaw ua tshuaj. Hom khoom siv no kuj yuav tsum muaj peev xwm muaj peev xwm tawg tau nyob rau hauv nws cov ciam teb, tiv thaiv kom tsis txhob kis mus rau ib puag ncig. Piv txwv ntawm cov cuab yeej tawg-pov thawj Class II suav nrog lub tshuab hluav taws xob, cov hluav taws xob tiv thaiv hluav taws xob, thiab cov khoom siv hluav taws xob plua plav.
Class III Explosion-Proof Equipment
Cov cuab yeej siv hauv chav kawm III yog tsim thiab siv rau hauv thaj chaw uas muaj cov khoom siv hluav taws xob tsis zoo lossis cov khoom siv hluav taws xob uas tsim cov khoom siv hluav taws xob yooj yim tuaj yeem tshwm sim. Cov cuab yeej siv hauv chav kawm no yog tsim tshwj xeeb los tiv thaiv cov nplaim taws lossis qhov kub ntawm qhov kub ntawm cov khoom siv hluav taws xob nyob ib puag ncig, nrog rau kev tiv thaiv kev tsim cov nqi hluav taws xob uas tuaj yeem cuam tshuam cov khoom siv hluav taws xob. Qee qhov piv txwv ntawm Chav Kawm III cov khoom pov thawj tawg muaj xws li lub tshuab nqus tsev, cov cuab yeej txiav, thiab cov tshuab ua textile.
Sib nrug los ntawm peb qhov kev faib tawm no, cov cuab yeej pov thawj tawg kuj tau faib raws li qib kev tiv thaiv lawv muaj. Qib ntawm kev tiv thaiv yog nyob ntawm theem ntawm kev tiv thaiv sab nraud tiv thaiv ib puag ncig, xws li dej, plua plav lossis cov khoom siv corrosive. Cov cuab yeej pov thawj tawg feem ntau tau muab faib ua rau qib kev tiv thaiv, xws li IP00 (tsis muaj kev tiv thaiv ib puag ncig) mus rau IP68 (kev tiv thaiv tsis tu ncua hauv dej).
Hauv kev xaus, cov khoom siv foob pob tawg ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv thiab txo qhov tawg hauv qhov chaw muaj kev phom sij. Raws li cov theem ntawm kev pheej hmoo thiab hom ntawm cov khoom siv hluav taws xob, cov khoom tawg-pov thawj tau muab faib ua cov chav sib txawv thiab qib kev tiv thaiv kom muaj kev nyab xeeb hauv kev lag luam sib txawv. Nkag siab txog cov kev faib tawm no yog qhov tseem ceeb rau kev ua raws li kev nyab xeeb, xaiv cov khoom siv, kev teeb tsa, thiab kev saib xyuas.
