Kumvetsetsa Kwambiri kwa Oxygen Sensor

Pali mitundu yambiri ya masensa, monga scania sensor, VW Oxygen Sensor, OPEL Nitrogen Oxide Sensor, BMW sensor, ndi MAF sensor.Masensa osiyanasiyana amagwiritsidwa ntchito m'malo osiyanasiyana.Lero nkhaniyi ititsogolera kudziko la masensa a oxygen.

Kodi Oxygen Sensor ndi chiyani?

Sensa ya okosijeni (yomwe nthawi zambiri imatchedwa "O2 sensing unit". O2 ndi njira yopangira mpweya wa okosijeni) imayikidwa mu utsi wambiri wa lorry kuti muyang'ane kuchuluka kwa okosijeni osayaka yomwe imatsalira mu utsi pamene mpweya umatuluka. injini.

Poyang'anira kuchuluka kwa okosijeni komanso kutumiza chidziwitsochi ku makina apakompyuta a injini yanu, masensawa amalola galimoto yanu kudziwa ngati mafuta amafuta akuthamanga kwambiri (osati mpweya wokwanira) kapena wowonda (oxygen wochuluka).Kuchuluka kwamafuta a mpweya ndikofunikira kuti galimoto yanu iziyenda bwino momwe imayenera kukhalira.Sensa ya okosijeni imagwira ntchito yofunika kwambiri pakugwira ntchito kwa injini, kutulutsa mpweya, komanso kuyendetsa bwino gasi,

Mfundo Yogwira Ntchito ya Sensor Oxygen

Mfundo yogwira ntchito ya sensa ya okosijeni ndikuwunika kuchuluka kwa okosijeni mkati mwa utsi.Choyamba, mpweya uwu unaphatikizidwa mu gasi woyaka kosatha.Kuyankhulana kwa sensa iyi kungapangidwe mothandizidwa ndi chizindikiro chamagetsi.Chifukwa chake mpweya womwe umayima mu utsiwo udzasankhidwa ndi makina apakompyuta agalimoto.

Kompyutayo imayang'anira kusakanikirana kwa gasi kapena mpweya woperekedwa kumagalimoto ndi injini zamagalimoto.Kukonzekera kwa sensit unit isanachitike & pambuyo pa chosinthira chothandizira amalola kuti asunge ukhondo wa utsi ndikuwunika momwe wosinthirayo amagwirira ntchito.

Mitundu ina ya Sensor Oxygen

Electrochemical oxygen sensor

Magawo a electrochemical oxygen sensing amagwiritsidwa ntchito poyesa kuchuluka kwa mpweya mumpweya wozungulira.Amayezera momwe ma chemical amachitira mkati mwa sensing unit yomwe imapanga zotsatira zamagetsi molingana ndi digiri ya okosijeni.Popeza masensa ena a electrochemical amapanga ma analogi awoawo, amatha kudzipangira okha, zomwe zimapangitsa kuti zikhale zopindulitsa pozindikira kuti batire la mpweya wa mpweya woyendetsedwa pansi pamadzi ndi zida zodzitetezera pamanja.Zitsanzo zitha kuphatikizira zowunikira mpweya, zowunikira kupuma, ndi masensa a glucose m'magazi.

Pankhani ya ubwino wa sensa, ma electrochemical sensing mayunitsi amafufuzidwa chifukwa cha kuchepa kwa mphamvu zawo, kuchepetsa malire ozindikira, ndipo nthawi zambiri sakhudzidwa mwachindunji ndi mpweya wotsutsana.Amakondanso kukhala ma sensor otsika mtengo kwambiri

Akupanga oxygen sensor

Masensa akupanga okosijeni amagwiritsa ntchito kuchuluka kwa mawu kuti athe kuyeza kuchuluka kwa mpweya mu gasi kapena madzimadzi.Mu madzimadzi, mayunitsi omveka opita kumtunda ndi kumunsi kwa mtsinje amayesa kusiyana kwa mlingo pakati pa mafunde apamwamba kwambiri.Kusintha kwa mlingo ndikofanana ndi mpweya mu chitsanzo.Mu mipweya, kuchuluka kwa ma audio kumasiyana monga momwe ma cell a gasi amasiyana.Izi zimapangitsa masensa a okosijeni akupanga kukhala opindulitsa kwa ma anesthesia ventilators kapena ma jenereta a okosijeni pomwe zotsatira zake zimakhala zodziwika bwino za mpweya wa okosijeni.Kugwiritsa ntchito pafupipafupi komwe kumafunikira njira zozindikirira mpweya wa okosijeni ndi zipatala, kusanthula gasi, kapena kugwiritsa ntchito zolumikizira mpweya kapena ma jenereta a okosijeni am'manja.

Zonsezi, chifukwa sensa ya okosijeni ili ndi mfundo yapadera yogwirira ntchito, choncho ingagwiritsidwe ntchito m'madera ambiri, monga kulongedza zakudya, zakumwa zakumwa, mankhwala ndi zachipatala, ndi zina zotero. Ndife ogulitsa mpweya wa okosijeni.Chidwi chilichonse, talandiridwa kuti mutilankhule.
