Kev xaiv kom raug ntawm cov pa roj toxic detector
Txheej txheem cej luam ntawm toxic gas sensors:
Toxic gas sensor yog ib qho khoom siv uas hloov cov pa phem hauv huab cua mus rau hauv cov teeb liab hluav taws xob. Lub teeb liab hluav taws xob tsim los ntawm lub sensor yog ua tiav, nthuav dav thiab hloov pauv los ntawm hluav taws xob circuits los tso saib thiab ceeb toom cov ntsiab lus roj teeb meem. Nws tuaj yeem pom tau tias lub sensor yog qhov tseem ceeb thiab cov ntsiab lus tseem ceeb ntawm kev kuaj pom cov pa phem thiab lub tswb. Nws qhov ua tau zoo txiav txim siab qhov zoo thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob kuaj pom thiab lub tswb. Sensors yog siv rau ntawm qhov chaw thiab raug cuam tshuam los ntawm ntau qhov chaw hnyav thiab huab cua. Tshwj xeeb tshaj yog cov sensors ntawm cov cuab yeej ruaj khov ua haujlwm tsis tu ncua rau lub sijhawm ntev thiab raug cuam tshuam rau kev tawg-pov thawj thiab cov khoom siv hluav taws xob txwv. Yog li ntawd, cov kev cai rau cov pa phem sensors yog nruj heev.
Cov txheej txheem rau xaiv cov khoom siv hluav taws xob tsis zoo thiab lub tswb nrov. (Xaiv qhov tseeb lub tshuab kuaj roj toxic)
1. Qhia meej txog lub hom phiaj nrhiav pom thiab xaiv hom twj paj nruag
Nyob rau hauv luv luv, nrhiav pom cov pa phem muaj ob lub hom phiaj. Qhov thib ib yog txhawm rau txheeb xyuas qhov tawg, thiab qhov thib ob yog txhawm rau kuaj cov tshuaj lom. Lub thiaj li hu ua explosion detection yog los xyuas cov ntsiab lus ntawm combustible gases nyob rau hauv qhov chaw txaus ntshai thiab ceeb toom rau overruns los tiv thaiv kev sib tsoo tawg; Kev kuaj tshuaj lom yog txhawm rau txheeb xyuas cov ntsiab lus ntawm cov pa roj carbon monoxide nyob rau hauv qhov chaw txaus ntshai thiab ceeb toom rau overruns los tiv thaiv cov neeg ua haujlwm los ntawm kev raug lom. Qhov ntsuas tawg yog 0~100% LEL, thiab qhov ntsuas tshuaj lom yog 0 ~ kaum (lossis pua pua) ppm. Muaj qhov sib txawv loj ntawm ob.
Muaj peb yam xwm txheej rau cov pa phem hauv qhov chaw uas muaj kev pheej hmoo: ua ntej, tsis muaj tshuaj lom (lossis tsawg-tshuaj lom) thiab flammable; thib ob, non-flammable thiab lom; thib peb, flammable thiab lom. Thawj ob qhov xwm txheej tsuas yog txiav txim siab: thawj zaug yog kuaj qhov tawg, qhov thib ob yog kuaj tshuaj lom, thiab qhov thib peb yog kuaj tshuaj lom yog tias ib tus neeg raug, thiab kuaj qhov tawg yog tias tsis muaj leej twg raug. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam nws
2. Tshem tawm lub hom phiaj nrhiav kom pom thiab xaiv hom cuab yeej (portable lossis tsau)
Tsau nrhiav kom pom lub tswb yog siv rau kev tshawb nrhiav kom pom qhov xau mus ntev hauv kev tsim khoom lossis chaw cia khoom; portable (los yog hnab tshos me me) cov cuab yeej siv rau lwm yam kev tshuaj xyuas, xws li kev saib xyuas, kev tshawb nrhiav thaum muaj xwm txheej ceev, kev nkag mus thiab kev soj ntsuam xyuas.
3. Qhia meej txog lub hom phiaj nrhiav pom thiab xaiv cov cuab yeej zoo tshaj plaws
Cov cuab yeej ntaus ntawv suav nrog peb lub ntsiab lus tseem ceeb: chaw tsim khoom, ntsuas kev ua haujlwm thiab cov ntsiab lus tshawb pom. Thaum xaiv hom twj paj nruag, cov txheej txheem hauv qab no yuav tsum tau txiav txim siab: cov chaw tsim khoom ncaj ncees, muaj lub koob npe zoo, tau lees paub cov khoom zoo, thiab muaj daim ntawv pov thawj tawg tawm los ntawm lub tuam txhab kev saib xyuas.
