Momwe mungayang'anire sensa ya fan

funso momwe mungayang'anire sensa ya fan, eni magalimoto angakhale ndi chidwi pamene chowotcha chozizira cha injini yamoto chamkati sichiyatsa kapena, mosiyana, chimagwira ntchito nthawi zonse. Ndipo zonse chifukwa nthawi zambiri chinthu ichi ndi chifukwa cha vuto. kuti muwone sensa kuti muyatse fani yoziziritsa, muyenera kudziwa mfundo ya ntchito yake, komanso kugwiritsa ntchito multimeter kuti muyese miyeso.

Musanayambe kulongosola ndondomeko yowunikira sensa ya radiator fan, ndikofunika kumvetsetsa momwe imagwirira ntchito ndi mitundu yake yolakwika.

Momwe sensor ya fan imagwirira ntchito

Kusintha kwa fan palokha ndikusintha kwa kutentha. Mapangidwe ake amachokera ku mbale ya bimetallic yolumikizidwa ndi ndodo yosunthika. Pamene chinthu chokhudzidwa cha sensa chikutenthedwa, mbale ya bimetallic imapindika, ndipo ndodo yomwe imamangiriridwapo imatseka magetsi a galimoto yozizira.

Mphamvu yamagetsi yamagetsi ya 12 volts (yokhazikika "plus") imaperekedwa nthawi zonse ku sensor switch-on sensor kuchokera pa fuseji. Ndipo "minus" imaperekedwa pamene ndodo imatseka magetsi.

Zomwe zimakhudzidwa zimakumana ndi antifreeze, nthawi zambiri mu radiator (m'munsi mwake, kumbali, zimatengera mtundu wagalimoto), koma pali mitundu ya ICE pomwe sensor ya fan imayikidwa mu cylinder block, monga mu galimoto yotchuka VAZ-2110 (pa jekeseni ICEs). Ndipo nthawi zina mapangidwe a injini zoyatsira mkati amatipatsa masensa awiri kuti atsegule fani, mwachitsanzo, pamapaipi olowera ndi potuluka a radiator. Izi zimakuthandizani kuti nonse muyatse ndikuzimitsa fani mokakamiza kutentha kwa antifreeze kutsika.

Ndikoyeneranso kudziwa kuti pali mitundu iwiri ya sensor kutentha kwa fan - pini ziwiri ndi pini zitatu. Zikhomo ziwiri zimapangidwira kuti zigwire ntchito pa liwiro limodzi, ndipo zikhomo zitatu zimapangidwira maulendo awiri. Liwiro loyamba limasinthidwa pa kutentha kochepa (mwachitsanzo, pa +92 ° С ... + 95 ° С), ndipo chachiwiri - pa kutentha kwakukulu (mwachitsanzo, pa +102 ° С ... 105С °).

Kutentha kosinthika kwa liwiro loyamba ndi lachiwiri nthawi zambiri kumawonetsedwa panyumba ya sensa (pa hexagon kwa wrench).

kulephera kwa sensa ya fan switch

Chophimba chozizira cha fan fan ndi chida chosavuta, chifukwa chake chimakhala ndi zifukwa zochepa zosweka. Izi sizingagwire ntchito ngati izi:

Zolumikizira pa chipangizo cha DVV cha pini zitatu

• Kulumikizana kumamatira. Pankhaniyi, faniyo idzathamanga nthawi zonse, mosasamala kanthu za kutentha kwa antifreeze.
• Lumikizanani ndi oxidation. Pankhaniyi, zimakupiza si kuyatsa konse.
• Kuwonongeka kwa relay (ndodo).
• Kuvala mbale ya bimetallic.
• Palibe mphamvu ya fuse.

Chonde dziwani kuti sensa ya fan switch ndi yosasiyanitsidwa ndipo siyingakonzedwe, chifukwa chake, ngati kulephera kuzindikirika, kumasinthidwa. M'galimoto yamakono, kuwala kwa injini ya cheke kudzawonetsa vuto, chifukwa chimodzi kapena zingapo mwa zolakwika zotsatirazi zidzalembedwa kukumbukira gawo lamagetsi (ECU) - p0526, p0527, p0528, p0529. Zizindikiro zolakwika izi zidzafotokozera dera lotseguka, chizindikiro ndi mphamvu, koma izi zidachitika chifukwa cha kulephera kwa sensa kapena ma waya kapena zovuta zolumikizira - mutha kuzipeza mutayang'ana.

Momwe mungayang'anire sensa ya fan

kuti muwone kugwira ntchito kwa sensor switch-on sensor, iyenera kuchotsedwa pampando wake. Monga tafotokozera pamwambapa, nthawi zambiri imakhala pa radiator kapena pa cylinder block. Komabe, musanagwetse ndikuyesa sensa, muyenera kuwonetsetsa kuti mphamvu imaperekedwa kwa iyo.

Kuwunika mphamvu

DVV Power Check

Pa multimeter, timayatsa njira yoyezera voteji ya DC mkati mwa pafupifupi 20 Volts (kutengera mtundu wa multimeter). Mu chip sensor cholumikizidwa, muyenera kuyang'ana magetsi. Ngati sensor ili ndi pini ziwiri, ndiye kuti muwona nthawi yomweyo ngati pali 12 volts pamenepo. Mu sensa yolumikizana ndi atatu, muyenera kuyang'ana voteji pakati pa zikhomo mu chip awiriawiri kuti mupeze pomwe pali "kuphatikiza" ndi komwe kuli "minus" iwiri. Pakati pa "plus" ndi "minus" iliyonse payeneranso kukhala voteji ya 12V.

Ngati palibe mphamvu pa chip, choyamba muyenera kuyang'ana ngati fuseyi ilibe (ikhoza kukhala mu chipika pansi pa hood ndi chipinda chokwera galimoto). Malo ake nthawi zambiri amawonetsedwa pachivundikiro cha bokosi la fuse. Ngati fuyusiyo ili bwino, muyenera "kuyimba" waya ndikuyang'ana chip. Ndiye ndikofunikira kuti muyambe kuyang'ana fan sensor yokha.

Komabe, musanayambe kukhetsa antifreeze ndikutsegula sensa yoziziritsa ya radiator, ndikofunikira kuchita mayeso ang'onoang'ono omwe angatsimikizire kuti fan ikugwira ntchito bwino.

Kuwona ntchito ya fan

Mothandizidwa ndi jumper iliyonse (chidutswa cha waya woonda), kutseka "kuphatikiza" awiriawiri ndi choyamba, ndiyeno "kuchotsa" chachiwiri. Ngati mawaya ali osasunthika, ndipo fani ikugwira ntchito, ndiye panthawi yozungulira, choyamba, ndiyeno yachiwiri ikuthamanga. Pa sensa yolumikizana ndi awiri, liwiro lidzakhala limodzi.

Ndikoyeneranso kuyang'ana ngati faniyo imazimitsidwa pamene sensa yazimitsidwa, ngati olumikizana atsekeredwa mmenemo. Ngati, pamene sensa yazimitsidwa, faniyo ikupitirizabe kugwira ntchito, ndiye izi zikutanthauza kuti pali chinachake cholakwika ndi sensa, ndipo chiyenera kuyang'aniridwa. Kuti muchite izi, sensor iyenera kuchotsedwa m'galimoto.

Kuyang'ana sensor kuti mutsegule fan

Mutha kuyang'ana DVV m'njira ziwiri - ndikuwotcha m'madzi ofunda, kapena mutha kutenthetsa ndi chitsulo chosungunulira. Onsewa akutanthauza kuwunika kopitilira. Pokhapokha, mudzafunika multimeter yokhala ndi thermocouple, ndipo koyamba, thermometer yomwe imatha kuyeza kutentha kuposa madigiri 100 Celsius. Ngati sensa yolumikizana ndi mafani atatu imayang'aniridwa, ndikuthamanga kwawiri (kuyikidwa pamagalimoto ambiri akunja), ndiye m'pofunika kugwiritsa ntchito ma multimeter awiri nthawi imodzi. Imodzi ndiyo kuyang'ana dera limodzi, ndipo yachiwiri ndikuyang'ana nthawi imodzi yachiwiri. Chofunikira cha mayesowo ndikupeza ngati relay imayatsidwa ikatenthedwa kutentha komwe kumawonetsedwa pa sensa.

Amayang'ana sensa kuti muyatse fani yoziziritsa ya radiator malinga ndi aligorivimu yotsatira (pogwiritsa ntchito chitsanzo cha sensa yamapini atatu ndi multimeter imodzi, komanso multimeter yokhala ndi thermocouple):

Kuyang'ana DVV m'madzi ofunda ndi multimeter

1. Khazikitsani multimeter yamagetsi ku "dialing" mode.
2. Lumikizani kafukufuku wofiyira wa ma multimeter ku kulumikizana kwabwino kwa sensa, ndi wakuda ku minus, yomwe imayang'anira kuthamanga kwa fan.
3. Lumikizani kafukufuku amene amayesa kutentha pamwamba pa chinthu chovuta cha sensa.
4. Yatsani chitsulo chosungunula ndikuyika nsonga yake ku chinthu chovuta cha sensor.
5. Pamene kutentha kwa mbale ya bimetallic kufika pamtengo wovuta (wosonyezedwa pa sensa), chojambula chogwira ntchito chidzatseka dera, ndipo multimeter idzawonetsa izi (muyimba, multimeter beeps).
6. Sunthani kafukufuku wakuda kuti "minus", yomwe imayambitsa liwiro lachiwiri la fan.
7. Pamene kutentha kumapitirira, pambuyo pa masekondi angapo, sensa yogwira ntchito iyenera kutseka ndi dera lachiwiri, pamene kutentha kwa pakhomo kumafika, multimeter idzaliranso.
8. Chifukwa chake, ngati sensa sitseka kuzungulira kwake panthawi yotentha, ndiyolakwika.

Kuyang'ana sensa yolumikizana ndi awiri kumachitika chimodzimodzi, kukana kokha kumafunika kuyeza pakati pa awiri okha olumikizana.

Ngati sensa imatenthedwa osati ndi chitsulo chosungunula, koma m'chidebe chokhala ndi madzi, onetsetsani kuti si sensor yonse yophimbidwa, koma chinthu chake chomvera! Pamene ikuwotcha (kuwongolera kumachitika ndi thermometer), ntchito yomweyi idzachitika monga momwe tafotokozera pamwambapa.

Mukagula sensor yatsopano yosinthira fan, iyeneranso kuyang'aniridwa kuti ikugwira ntchito. Pakadali pano, pali zinthu zambiri zabodza komanso zotsika mtengo zomwe zikugulitsidwa, chifukwa chake kuyang'ana sikungapweteke.

Pomaliza

Kuzizira kwa fan switch sensor ndi chipangizo chodalirika, koma ngati pali kukayikira kuti chalephera, ndiye kuti muyang'ane, muyenera multimeter, thermometer ndi gwero la kutentha lomwe lingatenthetse chinthu chovuta.
