Kusintha liwiro kachipangizo VAZ 2107

Pamene galimoto ikuyenda, VAZ 2107 speed sensor (nozzle) imapanga deta yothamanga yomwe imalowa mu injini yamagetsi yamagetsi. Kulephera kwake kumayambitsa zolakwika pakuwongolera jekeseni ndipo kumayambitsa kutsika kwa mphamvu ya injini komanso kuchuluka kwamafuta. Mutha kuyang'ana ndikusintha sensa nokha. Kuti muchite izi, muyenera garaja yokhala ndi dzenje lowonera, screwdriver yathyathyathya, kiyi 22 ndi multimeter kapena nyali yoyesera.

Mfundo ya ntchito ya liwiro sensa VAZ 2107

Kugwira ntchito kwa sensor yothamanga kumachokera ku Hall effect, yomwe imalongosola maonekedwe a mphamvu zamagetsi pamene kondakitala yemwe ali ndi mphamvu yachindunji amayikidwa mu maginito. Sensa imapanga ma pulses pamene phokoso lotulutsa la gearbox la VAZ 2107 likuzungulira. Pakati pa kilomita imodzi ndi galimoto, VAZ 2107 speed sensor imapanga pafupifupi 6000 pulses, mafupipafupi omwe amakulolani kudziwa liwiro lamakono.

Kodi speed sensor VAZ 2107 ili kuti

Sensa imalumikizidwa ndi bokosi la gear pa liwiro la kutumiza chingwe cha speedometer. Kuti muchotse ndikuyang'ana, muyenera kulumikiza chingwe cha Speedometer ku gearbox.

Zizindikiro

Chizindikiro chachikulu chazovuta pakugwira ntchito kwa sensa ndikutulutsidwa kwa code yolakwika yofananira ndi kompyuta yomwe ili pa board. Zowonongeka zimatha kuwonekanso mu zizindikiro zina:

• kuchuluka mafuta;
• kusayenda bwino kwa injini;
• idling kapena speedometer ikugwira ntchito ndi vuto lalikulu;
• osakhazikika osagwira ntchito.

Chenjerani! Zizindikiro zinayizi zikhoza kuyambitsidwa ndi mavuto ndi mbali zina za galimoto.

Zomwe zimayambitsa kusokonekera kwa sensa

Mapangidwe a sensa ndi odalirika kwambiri. Chifukwa cha kusagwira ntchito nthawi zambiri makutidwe ndi okosijeni wa kulankhula mu kachipangizo kapena chingwe wosweka ku sensa kuti injini ECU.

Zolumikizana ziyenera kuyang'aniridwa, ngati kuli kofunikira, kutsukidwa ndi kupakidwa mafuta ndi Litol. Ndibwino kuti muyambe kuyang'ana khomo la waya pamalo omwe ali pafupi ndi pulagi. Kumeneko amapindika nthawi zambiri, motero, amawombera ndi kusweka. Pankhaniyi, ndikofunikira kuyang'ana pansi kwa sensor. Kukaniza mu netiweki yanu kuyenera kukhala pafupifupi 1 ohm. Ngati palibe cholakwika, yang'anani liwiro la sensor. Kuti muchite izi, iyenera kuchotsedwa m'galimoto.

Momwe mungachotsere sensor yothamanga VAZ 2107

Kuti mutsegule sensor yothamanga, chitani izi:

• kukhazikitsa galimoto pamwamba pa dzenje lowonera;
• kuyatsa mabuleki oimika magalimoto;
• ikani mphete pansi pa mawilo;
• masulani mtedza wa chingwe choyendetsa liwiro kuchokera pa dzenje loyang'ana ndi screwdriver yathyathyathya;
• kulumikiza chingwe chotumizira;
• masulani chotchinga cha pulasitiki chogwirizira cholumikizira chochokera ku sensa yothamanga;
• akanikizire tatifupi kasupe ndikudula liwiro la sensor unit;
• ndi kiyi 22, masulani kachipangizo koyendetsa liwiro;
• chotsani sensor yothamanga.

VAZ 2107 liwiro sensa akhoza kufufuzidwa ndi multimeter kapena "wolamulira". Kuti muyike sensor, tsatirani njira zomwe zili pamwambazi motsatira dongosolo.

Kuyang'ana liwiro la sensor

Njira yosavuta yowonera sensor yothamanga ndikuyika ina m'malo mwake. Mtengo wa gawolo ndi wotsika, kotero iyi ndiyo njira yosavuta komanso yachangu kwambiri yowonetsetsa kuti imagwira ntchito kapena kusweka. Ngati palibe latsopano VAZ 2107 liwiro sensa pa dzanja, ndiye choyamba muyenera kufufuza wakale, ndiyeno kupita ku sitolo kwa latsopano.

Kuti muwone magwiridwe antchito a sensor yothamanga, muyenera chubu la pulasitiki laling'ono lokhala ndi m'mimba mwake lolingana ndi makulidwe a ndodo ya sensor, ndi voltmeter (multimeter). Cheke ikuchitika motere:

• gwirizanitsani voltmeter ku zotsatira za sensa yomwe imapereka zizindikiro zamagetsi, ndi "misa" ya galimoto;
• ikani chubu pa olamulira a sensa;
• tembenuzani chubu.

Chubu chikazungulira, voteji yomwe imachokera ku sensa iyenera kuwonjezeka molingana ndi liwiro la kuzungulira. Ngati izi sizichitika, m'malo VAZ 2107 liwiro sensa ayenera m'malo.

Langizo: Momwemonso, mutha kuyang'ana sensor yothamanga mwachindunji pamakina. Kuti muchite izi, muyenera kupachika imodzi mwa mawilo oyendetsa, kulumikiza voltmeter ku zotsatira za sensa ndi "nthaka" ndikuyamba kutembenuza mawilo. Ngati magetsi ndi ma pulses akuwoneka, sensor ili bwino.

M'malo mwa voltmeter, mungagwiritse ntchito nyali yoyesera. Pankhaniyi, poyang'ana magwiridwe antchito, ndikofunikira kugwiritsa ntchito voteji pa "positive" linanena bungwe la liwiro sensa. Ngati nyali ikuwunikira pamene sensa imazungulira, vuto siliri ndi sensa. Muyenera kuyang'ana zigawo zina ndi zigawo za "zisanu ndi ziwiri", zomwe zingakhudze ntchito ya injini ECU.
