Senzor Vaz goriva, znaci kvara na senzoru za auto gorivo, neuspjeh lijekova

Kad završi gorivo, izbor malog vlasnik automobila - ili opet oporaviti auto, a danas je to najjeftinije zadovoljstvo, ili hoda. Naravno, svi vozači imaju tendenciju da odaberete prvu opciju, međutim, vjerojatno ne bi trebali biti na takvim situacijama kada morate donijeti odluku odmah. Da biste izbjegli takve probleme i razinu goriva senzor je stvorio.

Senzor za gorivo Razina - Uređaj (DUT)

Olympus digitalni fotoaparat.

U ovom članku, naša pažnja bit će usmjerena na vozilima, gdje se koristi za razinu goriva, pretvaranje ove razine u volumen i prijenos dobivenih vrijednosti s digitalnim ili analognim put.

Ovaj uređaj se sastoji od metalne šipke montiran u spremnik za gorivo pomoću standardnog otvaranja ili posebno izrađenim otvorom pogodnom za promjeru. Senzor je spojen na sustav za praćenje vozila, kada je poslana potrebna podataka.

Često su visoke preciznosti univerzalne naprave, što ga čini moguće da ih koriste ne samo u prometu, te u drugim tehnikama, pa čak iu stacionarnim objektima - postrojenja, skladišta. Ova jedinica je usko povezana s pokazivačem razine goriva nalazi na ploči s instrumentima.

Do danas, postoji niz varijacija na DUT - univerzalni, ultrazvuk, float, digitalne, elektronske, ali je njihov zajednički cilj je jedan - ispravan definicija potrošnje goriva u spremniku, tako da svaki vozač ima mogućnost kontrole troškova goriva , Osim toga, uređaj omogućuje praćenje količine šljive (najkorisnijih opcija za taxi usluge, menadžeri poduzeća i drugih organizacija u kojima zaposlenici mogu spojiti malo goriva) i plinsko gorivo stanica (u kojoj volumen kada i gdje su provedena).

Za mogućnost detaljnije kontrole razine goriva, potrebno je ugraditi odgovarajući uređaj s minimalnim pogreške i povećanu osjetljivost na automobilu, koji će osigurati najtočniji pokazatelji.

spajanje senzora razine goriva

Postoje dvije metode povezivanja na mrežnu vozila, dizajn koji uključuje sklopku mase:

  1. Spajanje na mrežnu nakon prekidač mase. Senzor, u isto vrijeme, bit će bestrujno odmah nakon isključivanja mase automobila. U tom slučaju, bit će nemoguće saznati vremena odvod kada parkiralište će biti - senzor će biti isključen. Ovaj način povezivanja preporuča se za jeftinim senzore kojima nema galvanski spoj.

  2. Spajanje senzora na bateriju izravno. Ovaj način povezivanja je idealan iz praktičnog i funkcionalnog gledišta. Osim toga, veza je duting direktno na akumulator je sigurno, budući da je potrošnja struje senzora je samo 10 do 48 mA. Spojite Pro senzora senzora direktno na akumulator, jer su odlikuje prisutnost ugrađeni u galvanskom spoju do 3000 V. Osim toga, polimer tijelo ove senzora je izolator, kao rezultat od kojih svi električni krugovi su sigurno zaštićena od električnog kvara. Za spajanje drugih senzora direktno na akumulator, morat ćete montirati dodatni galvanska čvora.

senzor razine goriva ne radi

Dut, kao i bilo koje druge elemente automobila, sustavno može uspjeti, što je rezultiralo potrebom za popravak rad. Sada ćemo razmotriti u detalje najčešćih uzroka ovog fenomena:
004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

  1. Ako su očitanja stalno mijenjaju ( „preuzimanje”), kontakt pjesme su nosili na brodu, koji su pod utjecajem vremena, kao rezultat činjenice da trkač Uređaj je stalno u pokretu. Ako je izbrisani prostor nije velik, pokušati dobiti klizač tako da se nalazi iznad izbrisani mjestu, međutim, s velikom području depozita, to će biti moguće da se riješi problem samo zamjenom senzora.

  2. To se događa da s punim spremnikom goriva, indeks senzor strelicu vraća na nulu vrijednosti. Mogući uzrok ovog fenomena je pogrešno postavljena mjesto zaustavljanja limiter.
  3. Kad je motor pokrenut i paljenje uključeno, indeks strelicama ostaci fiksna. U pravilu, razlog leži oštećenje spojnih žica, oksidacija njihove savjete, kvar pokazivača prijemnika ili osigurača hrabrom.

  4. Ako je indeks razine goriva strelica stalno pada na nultu vrijednost, a istovremeno trzanje, struja kolektora treba provjeriti, to je vjerojatno nije dovoljno za otpornika senzora, ili otpornik navijanje je rez.
  5. Osim toga, minimalna goriva svjetlo upozorenja razina u spremniku može prestati raditi ili rade na pogrešan način, s prekidima. U tom slučaju, najvjerojatnije je problem u otpornika i svibanj morati biti zamijenjena.

Najčešći problem potenciometrijsko senzora je brzo trošenje, kao i oksidacija pjesama nego i određuje izgled od problema je gore opisano.

Provjerite gorivo senzora Vaz

Prije svega, trebali biste provjeriti otpor senzora, za što je potrebno učiniti sljedeće manipulacije:

004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

  1. Uklonite stražnje sjedalo.
  2. Mi odvrnuti zaštitni poklopac da VAZ se nalazi ispod stražnjeg sjedala.
  3. Mi odvrnuti umočiti i lagano ga iz spremnika plina.
  4. Zatim smo prebacili multimetar na način ohmmetar i izmjeriti otpor senzora u uvjetima različitih pozicija u opticaju: ako je plovak visi pod vlastitom težinom, otpor bi trebao biti od 280 do 330 oma; Prilikom podizanja plovak gore, otpor mora biti od 7 do 20 oma. Važno je napomenuti da su te vrijednosti dane za nisku ploči (instrument ploča je također visoka - brojevi za niske i visoke ploče su malo drugačiji).
    004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.
  5. Ako prilikom pomicanja plovak, otpor senzora ne mijenja ili se znatno razlikuje od željenog, senzor treba biti zamijenjena.
  6. Sa senzorom dobar, treba pažljivo ispitati njezin priključak i žica za masu koja dolazi iz senzora. Hrđa i oksida bi trebao biti odsutan jer ometaju pravilan i ispravan rad.

Ako je senzor radi, a indeks razine goriva ne radi točno, radimo sljedeće:

  1. Priključak osjetnika goriva karakterizira prisustvo dvije žice - ružičaste i plave. Lampa niska gorivo je trčanje plava u spremniku, od ružičaste - Indikator razine strelice.
    Olympus digitalni fotoaparat.
  2. Oružane s skakač (dio konvencionalnog žice), te sa svojim pomoć s paljenjem uključen zatvaranja roza žicu za masu. U tom slučaju strelica razine goriva trebala bi pokazati puni spremnik za gorivo.
  3. Zatim, uz pomoć skakača, povezujemo se s masom plave žice - svjetiljkom niskog goriva u spremniku treba okrenuti.
  4. Ako se tijekom zatvaranja na masu, pokazivač neće raditi, onda razlog ili u samom pokazivač, ili u jednoj od žica od senzora za gorivo na ploči s instrumentima.

Zamjena senzora razine goriva

Ako senzor razine goriva ne radi pogrešno, treba ga zamijeniti. Da biste to učinili, trebat će vam:

  1. Novi senzor.
  2. Crosshead odvijač.
  3. Rozhkovljeve kape ili glave.
  4. Odvijači.
  5. Ommeter.

004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

Važno je s obzirom na to da je senzor u izravnom kontaktu s gorivom, pa je potrebno pridržavati određenih sigurnosnih pravila. Prvo isključite bateriju. Nije potrebno da se u potpunosti ukloniti bateriju, samo isključite minus žice od terminala. Zatim demontirati senzor (kako to učiniti, mi ćemo gledati u nastavku). Ugradnja novih Duts proizvesti obrnutim redoslijedom. Kod sastavljanja poželjno je daljnji proces mjesto utičnicu brtve i tlačnog prstena pomoću sredstva za lijepljenje plina otporan.

kako ukloniti osjetnik razine goriva

Za uklanjanje najbolji, učinite sljedeće:

  1. Podignite sjedište drugog reda.
  2. Dalje, potrebno je očistiti područje tehničkog otvor od nakupljene prljavštine i prašine.
  3. Pomoću unakrsne odvijača, zakrenite vijke koji drže vrata.
  4. Odvojite kabelski svežanj od konektora.
    6F17EB6396B6EC174361AE2C5962B0A6.
  5. Onda smo okrenuti ključ „17”, a mi odvrnuti cijevi goriva na stranu, tako da ne ometaju rastavljanje tijelu benzinske postaje.
  6. Uz pomoć glave rta na „7” skrećemo pričvršćivanje matice koja popraviti tlačnog prstena.
  7. Ako matice Zakisli, koristite WD-40 ili druga slična sredstva.
  8. Uklanjanje svih privitaka i pritom prsten, nježno ukloniti cijeli čvor iz spremnika plina, zajedno s polugom i plovak.
  9. Sljedeći korak odvrne koristi kora odvijačem dva vijka koji drže senzor i oslobađanje električnog priključka pumpe.
    6F17EB6396B6EC174361AE2C5962B0A6.
  10. Zatim uzmemo iz vodilice iz kućišta crpke (Spone treba obnoviti pomoću odvijača).
  11. Na poklopcu pumpe, mi odvrnuti vijke, drži matice pomoću tipke na „5”.
  12. Uklanjanje poklopca, dobiti pristup senzoru.

Popravak senzora razine goriva

Kao što je gore spomenuto, najčešći uzrok kvara ili neispravnog rada nalazimo - trošenje kontakata trag senzora. U tom slučaju, možete premjestiti trkač na radno (nestabilan) dio staze, malo je izazvalo trkač montirati. Osim toga, provjerite „masa” okretanje pod „vodiča” za koroziju. Također, popravak možda morati biti uništen senzor kontakata.
