ʻO kekahi mau ʻike e pili ana i ka sensor oxygen

Kumu:

ʻO ka oxygen sensor kahi hoʻonohonoho maʻamau i ke kaʻa.Hoʻohana ia i nā mea koʻikoʻi seramika e ana i ka hiki o ka oxygen i loko o ka paipu hoʻopau kaʻa, a helu i ka ʻike o ka oxygen e pili ana i ke kumu kaulike kemika e nānā a hoʻopaʻa i ka lākiō ea-huehu e hōʻoia i ka maikaʻi o ka huahana maʻamau.

Hoʻohana nui ʻia ʻo Oxygen sensor i ka mālama ʻana i ka lewa o nā ʻano like ʻole o ka puhi ʻana i ka lanahu, ka ʻaila ʻaila, ka puhi ʻea, a me nā mea ʻē aʻe.Loaʻa iā ia nā pōmaikaʻi o ka hoʻolālā maʻalahi, pane wikiwiki, mālama maʻalahi, hoʻohana maʻalahi, ana pololei, a me nā mea ʻē aʻe. ʻO ka hoʻohana ʻana i ka sensor e ana a mālama i ka lewa puhi ʻaʻole hiki ke hoʻopaʻa wale a hoʻomaikaʻi i ka maikaʻi o ka huahana, akā hoʻopōkole hoʻi i ke kaʻina hana a mālama i ka ikehu. .

Kala

Hoʻohana ka mea ʻike oxygen i kaKumu Nernst.

ʻO ka mea nui he paipu ceramic ZrO2 porous, he electrolyte paʻa, me nā electrodes porous platinum (Pt) i hoʻopaʻa ʻia ma nā ʻaoʻao ʻelua.I kekahi mahana, ma muli o ka ʻokoʻa o ka oxygen ma nā ʻaoʻao ʻelua, ua hoʻopili ʻia nā molekole oxygen ma ka ʻaoʻao kiʻekiʻe (ka ʻaoʻao i loko o ka pahu ceramic 4) ma ka electrode platinum a hui pū me nā electrons (4e) e hana. oxygen iions O2-, ka mea e hana i ka electrode i hoʻopiʻi maikaʻi ʻia, O2 -Ke neʻe nei nā ion i ka ʻaoʻao haʻahaʻa o ka oxygen haʻahaʻa (ʻaoʻao hoʻopau kinoea) ma o nā hakahaka o ka oxygen i ka electrolyte, no laila ua hoʻopiʻi maikaʻi ʻia ka electrode, ʻo ia hoʻi, kahi hiki. hana ʻokoʻa.

Ke haʻahaʻa ka lākiō ea-wahie (huihui waiwai), emi ka oxygen i loko o ke kinoea hoʻopau, no laila he liʻiliʻi nā ion oxygen ma waho o ka paipu ceramic, e hana ana i ka ikaika electromotive ma kahi o 1.0V;

Ke like ka lakio ea-wahie me 14.7, ʻo ka ikaika electromotive i hana ʻia ma nā ʻaoʻao o loko a me waho o ka paipu ceramic he 0.4V ~ 0.5V, a ʻo kēia ikaika electromotive ka mana electromotive kuhikuhi;

Ke kiʻekiʻe ka lākiō ea-wahie (lean hui), ʻoi aku ka kiʻekiʻe o ka oxygen i loko o ke kinoea exhaust, a ʻo ka ʻokoʻa ʻokoʻa o ka oxygen ion ma waena o loko a me waho o ka pahu seramika he liʻiliʻi, no laila he haʻahaʻa loa ka ikaika electromotive i hana ʻia. kokoke i ka ʻole.

Hana

ʻO ka hana o ka mea ʻike e hoʻoholo i ka ʻike e pili ana i ka nui o ka oxygen i loko o ka exhaust ma hope o ka puhi ʻana o ka ʻenekini, ʻo ia hoʻi, ka ʻike o ka oxygen, a hoʻololi i ka ʻike oxygen i kahi hōʻailona uila a hoʻouna iā ia i ke kamepiula mīkini, no laila hiki i ka enekini ke hoʻomaopopo i ka mana pani pani me ka nui o ka ea e like me ka pahuhopu;e hōʻoia;Ka ekolu-ala catalytic mīkini hoʻololi i ka nui hoʻololi hoʻololi no ka ekolu pollutants o hydrocarbons (HC), carbon monoxide (CO) a me naikokene oxides (NOX) i loko o ka exhaust kinoea, a maximizes ka huli ana a me ka hoʻomaʻemaʻe o emission pollutants .

Ke kumu

Hoʻohana nui ʻia nā sensor oxygen i nā ʻoihana e like me ka petroleum, chemical, coal, metallurgy, papermaking, fire protection, administration municipal, lāʻau lapaʻau, nā kaʻa, a me ka nānā ʻana i ka emission gas.

ʻO YASEN kahi ʻoihana ʻoihana hana i ka hana ʻana i nā sensor oxygen VM, inā makemake ʻoe e kauoha iā lākou, e ʻoluʻolu e kelepona mai iā mākou!
