Qee cov ntaub ntawv hais txog oxygen sensor

Txoj Cai:

Cov pa oxygen sensor yog tus qauv teeb tsa ntawm lub tsheb.Nws siv cov ntsiab lus rhiab heev los ntsuas cov pa oxygen hauv lub tsheb tso cov yeeb nkab, thiab suav cov pa oxygen sib xyaw los ntawm cov ntsiab lus tshuaj sib npaug los saib xyuas thiab tswj cov pa roj carbon monoxide combustion los xyuas kom meej cov khoom zoo thiab cov khoom ntsuas uas ua tau raws li qhov tso pa tawm. txheem.

Oxygen sensor yog dav siv nyob rau hauv huab cua tswj ntawm ntau hom thee combustion, roj combustion, roj combustion, thiab lwm yam. Nws yog qhov zoo tshaj plaws combustion cua ntsuas txoj kev tam sim no.Nws muaj qhov zoo ntawm cov qauv yooj yim, cov lus teb ceev ceev, kev saib xyuas yooj yim, kev siv yooj yim, kev ntsuas raug, thiab lwm yam. Siv lub sensor los ntsuas thiab tswj cov huab cua combustion tuaj yeem tsis tsuas yog ruaj khov thiab txhim kho cov khoom zoo, tab sis kuj txo lub voj voog ntau lawm thiab txuag lub zog. .

Ua kom

Cov pa oxygen sensor siv lubNernst txoj cai.

Cov ntsiab lus tseem ceeb yog cov ntxeem tau ZrO2 ceramic raj, uas yog cov khoom siv electrolyte, nrog cov ntxeem tau platinum (Pt) electrodes sintered ntawm ob sab.Ntawm qhov kub thiab txias, vim muaj qhov sib txawv ntawm cov pa oxygen ntawm ob sab, cov pa oxygen molecules ntawm sab hauv siab (sab sab hauv ntawm lub raj ceramic 4) yog adsorbed ntawm platinum electrode thiab ua ke nrog cov electrons (4e) tsim. oxygen ions O2-, uas ua rau cov electrode zoo them, O2 - Cov ions tsiv mus rau qis oxygen concentration sab (kua pa sab) los ntawm cov pa oxygen ion vacancies hauv electrolyte, kom cov electrode tsis zoo, uas yog, muaj peev xwm. qhov txawv yog generated.

Thaum cov huab cua-roj piv qis qis (nplua nuj sib xyaw), muaj cov pa oxygen tsawg dua hauv cov pa tso pa, yog li muaj cov pa oxygen ions tsawg dua sab nraum lub raj ceramic, tsim lub zog hluav taws xob ntawm li 1.0V;

Thaum cov huab cua-roj piv yog sib npaug rau 14.7, lub zog hluav taws xob tsim tawm ntawm sab hauv thiab sab nrauv ntawm lub raj ceramic yog 0.4V ~ 0.5V, thiab lub zog hluav taws xob no yog siv lub zog hluav taws xob;

Thaum cov huab cua-roj piv yog siab (ntsib sib tov), ​​cov pa oxygen nyob rau hauv lub tso pa roj yog siab, thiab cov pa oxygen ion concentration txawv ntawm sab hauv thiab sab nraum ntawm lub ceramic raj yog me me, yog li cov generated electromotive quab yuam yog tsawg heev, ze rau xoom.

Muaj nuj nqi

Lub luag haujlwm ntawm lub sensor yog txiav txim siab cov ntaub ntawv hais txog seb puas muaj cov pa ntau dhau hauv cov pa tawm tom qab kev sib tsoo ntawm lub cav, uas yog, cov ntsiab lus oxygen, thiab hloov cov ntsiab lus oxygen rau hauv lub teeb liab voltage thiab xa mus rau lub tshuab computer, yog li ntawd. tias lub cav tuaj yeem paub qhov kaw-voj tswj nrog cov huab cua ntau dhau raws li lub hom phiaj;kom paub meej;Peb-txoj kev catalytic converter muaj qhov zoo tshaj plaws conversion efficiency rau peb cov pa phem ntawm hydrocarbons (HC), carbon monoxide (CO) thiab nitrogen oxides (NOX) nyob rau hauv cov pa pa, thiab maximizes kev hloov dua siab tshiab thiab purification ntawm emission pollutants.

Lub hom phiaj

Cov pa oxygen sensors tau siv dav hauv kev lag luam xws li roj av, tshuaj lom neeg, thee, metallurgy, papermaking, tiv thaiv hluav taws, kev tswj hwm hauv nroog, tshuaj, tsheb, thiab tshuaj xyuas cov pa roj.

YASEN yog lub chaw tsim khoom lag luam kev tshaj lij hauv kev tsim cov VM oxygen sensors, yog tias koj xav tau xaj lawv, txais tos hu rau peb!
