Yuav Tsum Tau Ua Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob Cov neeg siv yuav tsum paub
Daim ntawv thov ib puag ncig ntawm portable gas detectors feem ntau yog hnyav, thiab lawv tau tsim tshwj xeeb los ua kom tsis muaj dej thiab tsis muaj plua plav. Cov qib kev tiv thaiv ib txwm muaj txij li IP65 txog IP67, uas yog lub ntiaj teb kev tiv thaiv qib kev sawv cev. Ob tug lej kawg qhia txog cov plua plav thiab dej tsis zoo. IP65 qhia tau hais tias lub cuab yeej muaj plua plav pov thawj thiab muab kev tiv thaiv tiv thaiv dej; IP67 qhia tau hais tias lub cuab yeej muaj plua plav pov thawj thiab tiv thaiv los ntawm dej raus dej.
Kev tiv thaiv qib ntawm portable gas detectors nyob ntawm tus qauv qauv. Diffuse sampling muaj kev tiv thaiv ntau dua ntawm IP67, thaum lub twj tso kua mis nqus cov khoom tsuas tuaj yeem ua tiav IP65 vim lawv tsis muaj peev xwm ua kom tsis muaj dej tsis muaj roj nqus cov qauv. Kev tiv thaiv kev tsim tawm ntawm cov khoom siv hluav taws xob portable kuj tseem ceeb, feem ntau yog li ntawm 3 meters, 6 meters, thiab 8 meters. Yog tias qhov ntsuas tseem tuaj yeem siv tau ib txwm siv tom qab ntog los ntawm qhov siab ntawm 3 meters mus rau hauv av cement, nws tuaj yeem tiv taus ib puag ncig kev cuam tshuam, ntawm chav kawm, 8 meters yog qhov zoo tshaj plaws.
Raws li cov neeg siv cov khoom siv hluav taws xob portable, txhawm rau ua kom muaj kev ruaj ntseg ntawm lawv cov kev siv, cov neeg siv yuav tsum tau ua tib zoo saib xyuas cov cai hauv qab no:
1. Portable gas detectors muaj ib tug lifespan txwv, thiab portable gas detectors yog tsis muaj kev zam. Txawm hais tias lawv tsis siv ntau zaus, lawv tseem tuaj yeem ntsib kev laus. Nyob rau hauv dav dav, ntawm portable gas detectors, photoionization detectors muaj lub neej ntev tshaj ntawm plaub xyoos; Kev pabcuam lub neej ntawm LEL sensors yog thib ob, thiab lawv tuaj yeem siv tau ntau tshaj peb xyoos; Lub neej ntawm electrochemical tshwj xeeb roj sensors yog luv luv, feem ntau ntawm ib mus rau ob xyoos; Cov pa oxygen sensor tsuas yog siv tau li ntawm ib xyoos xwb.
2. Portable gas detectors tsuas tuaj yeem ua tiav kev ntsuas hauv qhov ntau, txwv tsis pub cov txiaj ntsig ntsuas yuav qis dua qhov tseem ceeb hauv koj ib puag ncig. Tsis tas li ntawd, kev ntsuas ntev dhau ntawm qhov ntau tuaj yeem ua rau muaj kev puas tsuaj rau lub sensor, uas ua rau cov txiaj ntsig tsis raug txawm tias nyob hauv qhov ntsuas qhov ntsuas tom qab.
3. Portable gas detectors feem ntau siv ib tug txheeb ze sib piv txoj kev rau kev ntsuas. Txoj kev ntsuas yog raws li nram no: ua ntej, calibrate lub ntsuas nrog ib tug standard concentration ntawm roj thiab ib tug xoom gas, thiab khaws cia tus qauv nkhaus nyob rau hauv lub ntsuas; Sib piv cov teeb liab hluav taws xob ntawm tus qauv concentration nrog cov teeb liab hluav taws xob tsim los ntawm kev ntsuas roj concentration, thiab xam cov nqi roj concentration kom raug.
