Amakuru amwe yerekeye sensor ya ogisijeni

Ihame:

Sensor ya ogisijeni ni iboneza risanzwe ku modoka.Ikoresha ceramic yibintu byapima ubushobozi bwa ogisijeni mumodoka isohoka mumodoka, ikanabara ihame rya ogisijeni ihuye nihame ryimiterere ya chimique kugirango ikurikirane kandi igenzure igipimo cy’ibicanwa biva mu kirere kugira ngo hamenyekane ubuziranenge bw’ibicuruzwa N'ibipimo byo gupima byujuje ibyuka bihumanya. bisanzwe.

Sensor ya Oxygene ikoreshwa cyane mugucunga ikirere cyubwoko butandukanye bwo gutwika amakara, gutwika amavuta, gutwika gaze, nibindi nuburyo bwiza bwo gupima ikirere cyo gutwika.Ifite ibyiza byuburyo bworoshye, igisubizo cyihuse, kubungabunga byoroshye, gukoresha byoroshye, gupima neza, nibindi. Gukoresha sensor mugupima no kugenzura ikirere cyaka ntigishobora gusa guhagarara neza no kuzamura ubwiza bwibicuruzwa, ariko kandi bigabanya umuvuduko wumusaruro no kuzigama ingufu .

Hindura

Rukuruzi ya ogisijeni ikoreshaIhame rya Nernst.

Ikintu cyibanze ni umuyoboro wa ZrO2 ceramic, ni electrolyte ikomeye, hamwe na electrode ya platine (Pt) yamenetse kumpande zombi.Ku bushyuhe runaka, bitewe nubushuhe butandukanye bwa ogisijeni kumpande zombi, molekile ya ogisijeni kuruhande rwinshi (uruhande rwimbere rwumubyimba wa ceramic 4) irashirwa kuri electrode ya platine hanyuma igahuza na electron (4e) kugirango ikore ogisijeni ion O2-, ituma electrode ishiramo neza, O2 -Iyoni zimuka kuruhande rwa ogisijeni nkeya (kuruhande rwa gaze ya gaze) binyuze mumyanya ya ogisijeni yabuze muri electrolyte, kugirango electrode yishyurwe nabi, ni ukuvuga ko bishoboka. itandukaniro ryakozwe.

Iyo igipimo cya lisansi yo mu kirere ari gito (imvange ikungahaye), haboneka ogisijeni nkeya muri gaze ya gaze, bityo hakabaho ion nkeya ya ogisijeni hanze ya ceramic ceramic, ikora ingufu za electromotive zingana na 1.0V;

Iyo igipimo cya lisansi yo mu kirere kingana na 14.7, ingufu za electromotive zitangwa kumbere yimbere ninyuma yumuyoboro wa ceramic ni 0.4V ~ 0.5V, kandi izo mbaraga nimbaraga zikoresha amashanyarazi;

Iyo igipimo cya peteroli yo mu kirere ari kinini (imvange itavanze), umwuka wa ogisijeni uri muri gaze ya gaze ni mwinshi, kandi itandukanyirizo rya ogisijeni ion hagati yimbere n’inyuma ya ceramic ni ntoya, bityo ingufu za electromotive zikabyara ni nke cyane, hafi ya zeru.

Imikorere

Imikorere ya sensor ni ukumenya amakuru yerekeye niba hari ogisijene irenze mumuriro nyuma yo gutwikwa na moteri, ni ukuvuga ibirimo ogisijeni, no guhindura ogisijeni mukimenyetso cya voltage hanyuma ikohereza kuri mudasobwa ya moteri, bityo ko moteri ishobora kumenya gufunga-kugenzura hamwe nikirere kirenze nkintego;kwemeza;Ihinduramiterere yinzira eshatu zifite uburyo bwiza bwo guhindura ibintu bitatu bihumanya hydrocarbone (HC), monoxyde de carbone (CO) na okiside ya azote (NOX) muri gaze ya gaze, kandi bigahindura cyane kandi bigahindura imyuka ihumanya ikirere.

Intego

Ibyuma bya Oxygene bikoreshwa cyane mu nganda nka peteroli, imiti, amakara, metallurgie, gukora impapuro, kurinda umuriro, ubuyobozi bwa komini, ubuvuzi, imodoka, no gukurikirana ibyuka bihumanya.

YASEN ni uruganda rukora umwuga wo gukora ibyuma bya ogisijeni ya VM, niba ukeneye kubitumiza, ikaze kutwandikira!
