Ib me ntsis txog gas detectors
1. Cov khoom siv hluav taws xob ruaj khov puas tuaj yeem ua rau hauv ob txoj kev xaim hluav taws xob?
Tsis yog, ob-xaim teeb liab thiab lub zog hluav taws xob sib koom ib lub xaim, thiab qhov siab tshaj plaws ua haujlwm tam sim no yog 20ma, thaum lub sijhawm ua haujlwm tam sim no ntawm cov roj hluav taws xob hluav taws xob yog 80ma, uas tsis tuaj yeem ua tau raws li nws qhov kev ua haujlwm tam sim no.
2. Yuav ua li cas thiaj li nrhiav tau qhov zoo ntawm lub tshuab ntsuas roj ruaj ruaj?
Raws li "Tsim Specifications for Detection and Alarms of Combustible and Toxic Gases in Petrochemical Enterprises" (SH3063-1999):
"3.0.8 Qhov kev pab cuam zoo kab rov tav dav hlau vojvoog ntawm lub combustible gas detector yuav tsum yog 7.5m nyob rau hauv tsev thiab 15m sab nraum zoov. Ib tug detector tuaj yeem ntsia tau rau hauv thaj chaw muaj txiaj ntsig zoo. Qhov kev ncua deb ntawm lub ntsuas pa roj thiab cov tso tawm qhov chaw, Nws yuav tsum tsis txhob loj dua 2m sab nraum zoov thiab 1m sab hauv tsev. "
3. Dab tsi yog cov cai ntawm kev teeb tsa qhov siab ntawm lub tswb ntsuas hluav taws xob ruaj khov?
Raws li "Tsim Specifications for Detection and Alarms of Combustible and Toxic Gases in Petrochemical Enterprises" (SH3063-1999):
"6.1.1 Cov khoom ntes uas ntes cov roj hluav taws xob lossis cov pa phem uas hnyav dua huab cua yuav tsum tau muab tso rau ntawm qhov siab ntawm 0.3 mus rau 0.6m ntawm pem teb (los yog hauv pem teb).
Lus Cim: Cov pa roj ntau dua {{0}}.97kg/m3 (raws li tus qauv) suav tias hnyav dua huab cua; cov pa roj tsawg dua 0.97kg / m3 (raws li tus qauv) yog suav tias yog sib dua li huab cua.
6.1.2 Cov khoom ntes uas ntes tau cov pa hluav taws xob lossis cov pa phem uas sib zog dua huab cua yuav tsum tau teeb tsa 0.5 txog 2m siab tshaj qhov tso tawm. "
4. Dab tsi ntawm cov qauv roj siv los ntsuas lub ntsuas roj hluav taws xob?
Raws li cov kev cai ntawm "Combustible Gas Detection Alarm" (JJG693-2004):
"5.1.2.1 Cov khoom siv roj siv tib yam khoom siv raws li cov roj ntsuas. Rau cov cuab yeej siv dav dav, cov khoom siv roj isobutane lossis propane tuaj yeem siv tau."
Lub tuam txhab siv isobutane rau calibration.
5. Lub hauv paus ntsiab lus ntawm kev tshawb nrhiav catalytic combustion yog dab tsi?
Lub hauv paus ntsiab lus ntawm catalytic combustion yog npaj ib tug high-temperature resistant catalyst txheej nyob rau saum npoo ntawm ib tug platinum resistor. Ntawm qhov kub thiab txias, cov pa roj hlawv catalytically hlawv ntawm nws qhov chaw. Lub combustion ua rau qhov kub thiab txias ntawm platinum resistor nce, ua rau kev hloov pauv. Tus nqi hloov pauv yog ib qho kev ua haujlwm ntawm qhov concentration ntawm cov pa taws. muaj nuj nqi.
6.FS sawv cev rau dab tsi?
FS yog lub ntsiab lus rau tag nrho cov nplai. Nws qhia qhov loj ntawm qhov ntsuas qhov ntau.
7. Cov ntxaij vab tshaus zoo li cas tam sim no nyob rau hauv kev ua lag luam thiab lawv cov yam ntxwv yog dab tsi?
Tam sim no, muaj lub teeb-emitting diodes (LED), kua siv lead ua kua (LCD) thiab cov organic teeb-emitting zaub (OLED) ntawm lub khw.
