Chii chekuita kana gauge yemafuta isingashande

Nguva dzose zvakakosha kuti mutyairi azive kuti ndeipi mileage yaachange aine mafuta asara akakwana mutangi. Iko kuverenga kweiyo chaiyo kukosha kwepakarepo kana avhareji mileage, huwandu hwemarita emafuta mutangi, uye kuchengetedza mileage inoitwa ne-on-board komputa, asi iyo mafuta level sensor (FLS) inopa ruzivo rwekutanga it.

Sezvo chimiro chetangi chisina kuchinjwa, vhoriyamu ine inozivikanwa inoshanda kutsamira padanho.

Chinangwa chegeji yemafuta mumotokari

Kusiyanisa pakati peinongedza uye sensor. Yekutanga iri pane dashboard uye museve kana digital pointer.

Chero zvazvingaitika, nhamba dzinodzokororwa nechiyero cheanalog, hazvina basa, muchimiro chechikamu chekuratidzira kana mudziyo wakasiyana une magnetoelectric drive yemuseve. Izvi zvakanyanya mutero kune tsika pane chinodiwa, asi ndizvo zvazviri.

Iyo pointer yakabatana kune sensor, uye hunhu hwemagetsi ezvishandiso zvese zviri zviviri zvinosarudzwa nenzira yekuti iko kukanganisa ndiko kudiki kunobvumidzwa pane chero nzvimbo pachikero.

Izvo hazvifanirwe kuve nemutsara hunhu hweinongedza uye FLS. Uyezve, ivo vanenge nguva dzose vasina-mutsara. Asi kana maitiro maviri akaiswa pamusoro peimwe pane imwe, uye kuwedzera kusiri mutsara kwechiyero kwakawedzerwa kwavari, ipapo iyo inoratidzwa ruzivo inogona kuvimbwa.

Muchiitiko chekugadzirisa kombiyuta yechiratidzo che sensor, haufaniri kunetseka pamusoro pekuvimbika kwekuverenga. Iyo software controller inokwanisa kuita chero yakanyanya kuomesesa basa, kunyangwe isina kuratidzwa nekuongorora. Zvakakwana kuenzanisa kuverenga, kunoitwa panguva yekuvandudza.

Iyo yakanyanya kuomesesa fomu yetangi, uko, zvichienderana nenzvimbo yezinga remafuta, kufamba kweiyo sensor yekutyaira chinhu kunokanganiswa nehuwandu hwakasiyana hwemvura mumayuniti evhoriyamu, inoiswa mundangariro yechigadzirwa nenzira ye table.

Zvakare, muridzi anogona kugara achiisa ega ega ekugadzirisa zvinhu panguva yemaitiro ekugadzirisa kuti averenge zvakanyanya. Aya ndiwo maitiro emakomputa epasirese pabhodhi, akaiswa semichina yekuwedzera, anowanzo shanda.

Nzvimbo yechigadzirwa

LLS inogara yakaiswa zvakananga mutangi remafuta. Dhizaini yayo inoshingirira peturu kana dhiziri mhute uye kupinda kuri kuburikidza neflange riri pamusoro petangi, rinowanzobatanidzwa nechiteshi chebasa chepombi yemafuta.

Iyo sensor pachayo inowanzobatanidzwa mune imwechete module nayo.

Mhando dzemafuta level sensors

Pane mitemo yakawanda yekushandura nzvimbo kuva chiratidzo chemagetsi.

Vamwe vanogadzirisa chaizvo chinzvimbo cheyero yemvura, kureva, miganhu pakati pezvinhu zve densities dzakasiyana, asi zvinokwanisika kuyera vhoriyamu zvakananga. Iko hakuna kudikanwa kwakakosha kweizvi, uye michina ichave yakaoma uye inodhura.

Pane akati wandei mamisimboti:

• electromechanical;
• electromagnetic;
• capacitive;
• ultrasonic.

Panogonawo kuve nekusiyana munzira yekutaurirana neinongedza:

• analog;
• frequency;
• impulse;
• encoded zvakananga neiyo data bhasi algorithm.

Iyo iri nyore mudziyo, iyo yakawanda inogadzirwa, mutengo unenge wakasarudzika. Asi kunewo maitiro anokosha, akadai sekutengeserana kana mitambo, uko kururama uye kugadzikana kunonyanya kukosha.

Mudziyo uye musimboti wekushanda

Kazhinji, kutonga kwepamusoro kunoitwa uchishandisa float. Inogona kubatanidzwa kune converter nenzira dzakasiyana.

float

Iyo iri nyore ndeyekubatanidza iyo inoyangarara kune yekuyera potentiometer uchishandisa lever. Kufambisa chinzvimbo chemuunganidzi wezvino kunokonzera shanduko mukupikiswa kweiyo inopikisa resistor.

Inogona kunge iri mune yakapfava waya vhezheni kana muchimiro cheseti yeanopikisa ane matepi uye ekubata mapedhi, paya panofamba muteresi, akabatana nekuyangarara kuburikidza nerevheti.

Midziyo yakadaro ndiyo yakachipa, asiwo ndiyo isina kururama. Kana uchibatanidza komputa, dzinofanirwa kuverengerwa nekudzora kuzadza neanozivikanwa mavhoriyamu emafuta.

Magnetic

Iwe unogona kubvisa chibatiso nekubatanidza potentiometer kune inoyangarara nemagineti. Magineti echigarire akabatana nekuyangarara anofamba achitevedza hurongwa hwemapadhi ekubata nemapombi kubva kune akaremerwa firimu resistors. Simbi inochinjika mahwendefa ari pamusoro pemapuratifomu.

Zvichienderana nechinzvimbo chemagineti, mumwe wavo anokwezvwa kwairi, achivhara papuratifomu inoenderana. Kupokana kwakazara kweseti yezvidziviriro zvinoshanduka zvinoenderana nemutemo unozivikanwa.

Zvemagetsi

Kuvapo kwezvinhu zvemagetsi mu sensor inobvumira zvakasiyana siyana zvemidziyo kuti ibatanidzwe muchikamu ichi. Semuenzaniso, sensor capacitive, apo mahwendefa maviri e-capacitor anowanikwa vertically mutangi.

Sezvo ichizadza nemafuta, iyo capacitance ye capacitor inoshanduka nekuda kwekusiyana kwe dielectric nguva dzose pakati pemhepo nemafuta. Bhiriji rekuyeresa rinotora kutsauka kubva kune zita uye rinorishandura kuita chiratidzo chenhanho.

Iyo ultrasonic sensor ndeye miniature emitter yeakakwira-frequency acoustic mafungu uye inogamuchira yechiratidzo chinoratidzwa. Nekuyera kunonoka pakati pekuburitsa uye kufungisisa, chinhambwe kusvika padanho chinogona kuverengerwa.

Zvinoenderana nerudzi rwechiratidziro, budiriro iri kuenderera munzira yekuparadzanisa sensor mune yakazvimirira node yebhazi remota imwe. Kufanana nemimwe michina yese, inokwanisa kufambisa ruzivo pabhazi iri ichipindura chikumbiro kubva padhibhodhi.

Zvinetso zvakajairika

Kutadza kweFLS kunorekodhwa nekuverenga kwayo kwakashata kana kusavapo kwavo zvachose. Muchiitiko chakajairika chekubatanidza kwemuchina neyakayangarara uye analog potentiometer, tsono yekunongedza inotanga kuzununguka, kuwedzeredza kana kurerutsa kuverenga. Izvi zvinenge nguva dzose nekuda kwekupfeka kwemakanika kweboka rekusangana reiyo inosiyana resistor.

Kesi yechipiri inowanzoitika ndeyekushanduka kwehuwandu hwekuyangarara nekuda kwekushatiswa kwezvinhu kana kuizadza nemafuta. Kusvika pakupedza kunyura uye kugara zero kuverenga.

Masensa emagetsi muchiitiko chekusashanda kwezvinhu zvinongorega kupa kuverenga. Dzimwe nguva izvi zvinokonzerwa ne wiring iyo isingadzivirirwe zvishoma kubva kune kunze kwekunze. Zviratidzo zvinokundikana kazhinji zvishoma.

Maitiro ekutarisa mashandiro eiyo sensor

Pamudziyo wega wega une potentiometer, pane tafura yekuenzanisa yehukama pakati pekupokana uye mwero wemafuta.

Zvakakwana kutora zviyero ne multimeter mune ohmmeter modhi pane akati wandei mapoinzi, semuenzaniso, tangi isina chinhu, yekuchengetedza stock, avhareji nhanho uye yakazara tangi.

Nekukanganisa kwakakura kana kuputsika, sensor inorambwa.

Nzira dzekugadzirisa gauge yemafuta

FLS yemazuva ano haigoni kugadziriswa uye inotsiviwa segungano. Mushure mekutarisa wiring uye kuedza kushorwa pachibatanidza, sensor inobviswa kubva mutangi pamwe chete nepombi uye kutenderera pachitsiko.

Izvi zvinoda kusvika kumusoro kwetangi, kazhinji inowanikwa pasi pecushion yekumashure kana muhunde. Iyo sensor inobviswa kubva pombi module uye inotsiviwa neimwe itsva.

Kusarudzika kunogona kucherechedzwa kupaza kwewaya. Soldering uye kuparadzanisa nzvimbo dzekuputsika kunoitwa. Asi kazhinji chikonzero chekukundikana ndeyekupfeka kweiyo friction surfaces mu potentiometer.

Kudzoreredza kwayo kunokwanisika, asi hazvigoneke, chigadzirwa chakagadziridzwa hachina kuvimbika, uye chitsva hachidhuri.
