Kuziziritsa fani sensor

Magalimoto ambiri amakono ali ndi fan yamagetsi ya radiator, yomwe yalowa m'malo mwa ma viscous couplings osagwira ntchito. Sensa ya fan (fan activation sensor sensor) imayang'anira kuyatsa fani, komanso kusintha liwiro).

Nthawi zambiri, zoziziritsa kuziziritsa za fan activation sensors:

• odalirika mokwanira;
• bwino kuwongolera fani;
• Ma sensa a fan ndi osavuta kusintha;

Panthawi imodzimodziyo, ndikofunikira kukonza zolakwika zazing'ono za chipangizo ichi chowongolera, chifukwa kuwonongeka kwa fani yozizirira kungayambitse kutentha kwa injini. Muyeneranso kudziwa momwe mungayang'anire ndikusintha sensa ya fan. Werengani zambiri m'nkhani yathu.

Kodi sensor ya fan ili kuti

The fan on/off sensor ndi chipangizo chamagetsi choyatsa ndikuwongolera magwiridwe antchito a fani yamagetsi yozizirira. Sensa imayendetsedwa kutengera miyeso ya kutentha kozizira. Ntchito yowunikirayi imatsimikizira malo omwe fan switch sensor ili.

The radiator fan activation sensor ili kumbali ya radiator kapena kumtunda kwake (pakati kapena mbali). Pachifukwa ichi, sensa iyi nthawi zambiri imatchedwa sensor ya heatsink. Kuti mumvetse bwino komwe sensor switch switch ili, muyenera kuphunzira padera buku laukadaulo lagalimoto inayake.

Sensa mu radiator imayambitsidwa ndi kutentha kwa ozizira. Ngati madzi akuwotcha mpaka 85-110 digiri Celsius, zolumikizira "zitsekeka" ndipo chowotcha chamagetsi chimayatsa, ndikuwomba injini.

Chotsatira chake ndi kutentha kwachangu. Kuphatikiza apo, masensa samangotembenuza ndi kuzimitsa fan yozizira, komanso amatha kusintha liwiro lake. Ngati kutentha sikuli kwakukulu, liwiro lidzakhala lochepa. Pa kutentha kwambiri, fani imathamanga kwambiri.

Mitundu ya ma radiator sensors

Masiku ano m'magalimoto osiyanasiyana mungapeze mitundu ikuluikulu ya masensa awa:

1. Sensa ya parafini;
2. Bimetallic;
3. Zamagetsi zopanda contactless.

Mtundu woyamba umachokera pa voliyumu ya hermetic yodzazidwa ndi sera kapena thupi lina lomwe lili ndi zinthu zofanana (kuchuluka kwa coefficient of expansion). Mayankho a Bimetal amagwira ntchito pamaziko a mbale ya bimetal, pamene mayankho osalumikizana amakhala ndi thermistor.

Bimetallic ndi parafini kukhudzana masensa kuti kutseka ndi kutsegula zimakupiza dera malinga ndi kutentha kwa ozizira. Komanso, sensa yamagetsi sichitseka dera ndipo imangoyesa kutentha, kenako imatumiza chizindikiro ku kompyuta. Gawo loyang'anira ndiye limayatsa fani ndikuyimitsa.

Masensa olumikizana amathanso kukhala amodzi-liwiro (gulu lolumikizana limodzi) ndi liwiro ziwiri (magulu awiri olumikizana) pomwe liwiro la fan likusintha malinga ndi kutentha.

Mwachitsanzo, VAZ zimakupiza poyatsira kachipangizo ntchito mu osiyanasiyana kutentha osiyanasiyana: 82 -87 madigiri, 87 - 92 madigiri ndi 92 - 99 madigiri. Panthawi imodzimodziyo, magalimoto akunja ali ndi magawo 4, malo apamwamba ndi 104 mpaka 110.

Chida cha sensor ya radiator

Ponena za chipangizocho, mwadongosolo ndi mkuwa wotsekedwa kapena bokosi lamkuwa lomwe lili ndi chinthu chovuta mkati. Kunja kuli ulusi, komanso cholumikizira magetsi. Chophimbacho chimakulungidwa kwa radiator kudzera pa O-ring pa cholowera chamadzi otentha (pafupi ndi nozzle yamagetsi).

Sensa imalumikizana mwachindunji ndi chozizira. Makina ena amakhala ndi masensa awiri nthawi imodzi (pa cholowera cha radiator ndi potuluka) kuti athe kuwongolera kuziziritsa koyenera komanso kosinthika.

Masensa ali ndi ulusi wa M22x1,5, komanso 29 mm hexagon. Pa nthawi yomweyi, pali njira zina zomwe ulusi ndi wocheperako, M14 kapena M16. Ponena za cholumikizira chamagetsi, cholumikizira ichi chili kumbuyo kwa sensa, koma pali masensa pomwe cholumikizira chili padera pa chingwe.

Momwe mungayang'anire sensor ya fan ndikuyisintha

Ngati zimakupiza si kuyatsa mu nthawi kapena injini nthawi zonse kutenthedwa, m'pofunika kuyang'ana radiator sensa. Masensa olumikizana amatha kufufuzidwa ndi manja anu mu garaja wamba.

Chonde dziwani kuti chinthu choyamba choyenera kuyang'ana si sensor yokha, koma kuzizira kwa fan fan ndi waya. Kuti muchite izi, muyenera kulumikiza mawaya a sensor ndikufupikitsa. Ngati pali mawaya atatu, timatseka pakati ndikumaliza motsatizana. Nthawi zambiri, fan iyenera kuyatsa pa liwiro lotsika komanso lalitali. Ngati imayatsa, ndiye kuti mawaya ndi relay ndi zachilendo ndipo muyenera kuyang'ana sensa.

Kuti muwone, tengani chidebe cha zoziziritsa kukhosi, kiyi yochotsa sensa ndi thermometer, komanso mufunika multimeter, mphika wamadzi ndi chitofu.

1. Kenako, batire yotsekera imachotsedwa, pulagi yotulutsa radiator imachotsedwa ndipo madzi amathiridwa;
2. Pambuyo pakukhetsa madziwo, pulagi imakulungidwa mmbuyo, mawaya a sensor amachotsedwa, pambuyo pake sensor iyenera kumasulidwa ndi kiyi;
3. Tsopano madzi amathiridwa mu poto kuti aphimbe sensa, pambuyo pake poto imayikidwa pa chitofu ndipo madzi amatenthedwa;
4. Kutentha kwa madzi kumayendetsedwa ndi thermometer;
5. Mofananamo, muyenera kulumikiza kukhudzana kwa multimeter ndi sensa ndikuyang'ana "dera lalifupi" pa kutentha kosiyana;
6. Ngati zolumikizira sizikutseka kapena zosokoneza zimadziwika, sensor ndiyolakwika ndipo iyenera kusinthidwa.

Ponena za kusintha sensa ya fan, njira yonseyo imatsikira pakumasula sensor yakale ndikumangirira mu yatsopano. Ndikofunikiranso kusintha gasket (O-ring).

Kenako, muyenera kuyang'ana mulingo wa antifreeze, onjezani madzi ngati kuli kofunikira ndikuwunika momwe makinawo amagwirira ntchito (kuwotcha injini ndikudikirira kuti fan iyatse).

ayamikira

1. Ndikofunika kumvetsetsa kuti sensa ya fan ndi gawo laling'ono koma lofunika kwambiri la dongosolo lozizira. Pankhaniyi, kachipangizo kameneka kamasiyana ndi kachipangizo kozizira kozizira. Ngati sensa ya radiator ikalephera, zotsatira zake zitha kukhala kutenthedwa kwakukulu kwa injini kapena kuwonongeka kwakukulu kwa dongosolo lozizirira. Pazifukwa izi, ndikofunikira kuyang'anira kulondola kwa mafani komanso magwiridwe antchito. Ponena za kusintha kwa sensa ya radiator, mutha kukhazikitsa zonse zoyambirira komanso zosinthira ndi ma analogues. Chinthu chachikulu chomwe muyenera kuganizira posankha ndikuti sensa yatsopano iyenera kukhala ndi kutentha komweko komwe kumayatsa ndi kuzimitsa fani, yoyenera voteji ndi mtundu wolumikizira.
2. Komanso dziwani kuti kutenthedwa kwa injini sikumakhudzana nthawi zonse ndi sensa ya fan. The kutenthedwa kuzirala dongosolo amafuna mwatsatanetsatane diagnostics (kuyang'ana mlingo ndi khalidwe antifreeze, kuwunika zolimba, kuthetsa kuthekera airing, etc.).
3. Zimachitikanso kuti zimakupiza motor zimalephera kapena masamba amakutha. Pankhaniyi, zinthu zonse zolakwika ziyenera kusinthidwa, ndipo sensa pa radiator sichiyenera kusinthidwa. Njira imodzi kapena imzake, pazochitika zilizonse, kuwunika kwa akatswiri kumafunika, pambuyo pake mavuto ndi makina oziziritsa a injini amachotsedwa ndi njira yophatikizira.
