Yadda ake duba firikwensin fan

Tambayarku yadda ake duba firikwensin fan, Masu motoci na iya sha'awar lokacin da injin konewa na cikin gida mai sanyaya fanko ba ya kunna ko, akasin haka, yana aiki koyaushe. Kuma duk saboda sau da yawa wannan sinadari ne ke haifar da irin wannan matsala. Don bincika firikwensin don kunna fan mai sanyaya, kuna buƙatar sanin ƙa'idar aikinsa, kuma yakamata ku yi amfani da multimeter don ɗaukar wasu ma'auni.

Kafin ci gaba zuwa bayanin hanyar don bincika firikwensin mai kunna fan na radiator, yana da kyau fahimtar yadda yake aiki da nau'ikan rashin aikin sa.

Yadda firikwensin fan ke aiki

Maɓallin fan da kansa shi ne yanayin zafi. Zanensa ya dogara ne akan farantin bimetallic da aka haɗa da sanda mai motsi. Lokacin da zafin na'urar firikwensin ya yi zafi, farantin bimetallic yana lanƙwasa, kuma sandar da aka makala da ita tana rufe da'irar wutar lantarki na injin sanyaya.

Madaidaicin ƙarfin injin na 12 volts (m "plus") koyaushe ana ba da shi zuwa firikwensin mai kunna fan daga fis. Kuma ana ba da "minus" lokacin da sanda ya rufe da'irar lantarki.

Abun da ke da mahimmanci yana zuwa cikin hulɗa da maganin daskarewa, yawanci a cikin radiator (a cikin ɓangarensa, a gefe, ya dogara da ƙirar mota), amma akwai samfuran ICE inda aka sanya firikwensin fan a cikin shingen Silinda, kamar a cikin sanannen mota Vaz-2110 (akan ICEs injector). Kuma wani lokacin zanen wasu injunan konewa na ciki yana samar da na'urori masu auna firikwensin guda biyu don kunna fanka, wato, kan bututun shigar da bututun radiyo. Wannan yana ba ku damar kunnawa da kashe fan da ƙarfi lokacin da zafin jiki ya faɗi.

Hakanan yana da daraja sanin cewa akwai nau'ikan firikwensin zafin fan iri biyu - fil biyu da fil uku. An ƙera fil biyu don aikin fan a gudu ɗaya, kuma fil uku an tsara su don saurin fan biyu. Ana kunna gudu na farko a ƙananan zafin jiki (misali, a +92 ° C… + 95 ° C), kuma na biyu - a zafin jiki mafi girma (misali, a +102 ° C… 105C°).

Ana nuna yawan zafin jiki na sauyawar saurin farko da na biyu daidai a kan mahalli na firikwensin (a kan hexagon don maƙarƙashiya).

gazawar fan sauya firikwensin

Firikwensin mai kunna fan sanyaya na'ura ce mai sauƙi, don haka tana da ƴan abubuwan da ke haifar da lalacewa. Yana iya yin aiki a irin waɗannan lokuta:

Masu haɗawa akan guntu DVV mai fil uku

• Tuntuɓi mai sanda. A wannan yanayin, fan zai yi aiki akai-akai, ba tare da la'akari da zafin jiki na maganin daskarewa ba.
• Tuntuɓi oxidation. A wannan yanayin, fan ba zai kunna ko kaɗan ba.
• Karyewar relay (sanda).
• Saka farantin bimetallic.
• Babu wutar lantarki.

Lura cewa firikwensin sauya fan ba ya rabuwa kuma ba za a iya gyara shi ba, saboda haka, idan an gano gazawar, an canza shi. A cikin motar zamani, hasken injin duba zai nuna matsala, tun da ɗaya ko fiye daga cikin kurakurai masu zuwa za a rubuta su a cikin ƙwaƙwalwar ajiyar lantarki (ECU) - p0526, p0527, p0528, p0529. Waɗannan lambobin kuskure za su ba da rahoton buɗaɗɗen da'ira, duka sigina da ƙarfi, amma wannan ya faru ne saboda gazawar firikwensin ko matsalolin wayoyi ko haɗin haɗin kai - zaku iya ganowa kawai bayan dubawa.

Yadda ake duba firikwensin fan

Domin duba yadda na'urar firikwensin kunna fan ke aiki, dole ne a tarwatsa shi daga wurin zama. Kamar yadda aka ambata a sama, yawanci ana samuwa ko dai a kan radiyo ko a cikin shingen Silinda. Koyaya, kafin tarwatsawa da gwada firikwensin, kuna buƙatar tabbatar da cewa an samar da wutar lantarki gare shi.

Binciken wutar lantarki

Duban Wutar DVV

A kan multimeter, muna kunna yanayin auna wutar lantarki na DC a cikin kewayon kusan 20 Volts (ya danganta da takamaiman ƙirar multimeter). A cikin guntu firikwensin da aka cire, kuna buƙatar bincika ƙarfin lantarki. Idan firikwensin yana da fil biyu, to nan da nan za ku ga idan akwai 12 volts a wurin. A cikin firikwensin lamba uku, yakamata ku duba ƙarfin lantarki tsakanin fil ɗin da ke guntu bibiyu don nemo inda akwai “plus” ɗaya kuma inda akwai “minuses” biyu. Tsakanin "plus" da kowane "raguwa" dole ne a sami ƙarfin lantarki na 12V.

Idan babu wutar lantarki a guntu, da farko kana buƙatar duba ko fuse ba shi da kyau (zai iya zama duka a cikin toshe a ƙarƙashin kaho da a cikin motar fasinja). Ana yawan nuna wurin sa akan murfin akwatin fiusi. Idan fis ɗin ba shi da kyau, kuna buƙatar "ring" wayoyi kuma duba guntu. Sa'an nan yana da daraja fara duba fan firikwensin kanta.

Koyaya, kafin cire daskarewa da kwance firikwensin radiyo mai sanyaya fan firikwensin, yana da kyau a yi ƙaramin gwaji ɗaya wanda zai tabbatar da cewa fan ɗin yana aiki da kyau.

Duba aikin fan

Tare da taimakon kowane mai tsalle (wani yanki na waya na bakin ciki), rufe "plus" a cikin nau'i-nau'i da na farko, sannan na biyu "raguwa". Idan na'urar ta kasance daidai, kuma fan yana aiki, to a lokacin da'irar, na farko daya sannan na biyu gudun fan zai kunna. A kan firikwensin lamba biyu, saurin zai zama ɗaya.

Hakanan yana da kyau a duba idan fan yana kashe lokacin da aka kashe firikwensin, idan lambobin sadarwa sun makale a ciki. Idan, lokacin da aka kashe firikwensin, fan ya ci gaba da aiki, to wannan yana nufin cewa wani abu ba daidai ba ne tare da firikwensin, kuma yana buƙatar dubawa. Don yin wannan, dole ne a cire firikwensin daga abin hawa.

Ana duba firikwensin don kunna fan

Kuna iya duba DVV ta hanyoyi biyu - ta hanyar dumama shi a cikin ruwan dumi, ko kuma kuna iya dumama shi da ƙarfe. Dukansu biyu suna nuna ci gaba da bincike. Sai kawai a cikin akwati na ƙarshe, kuna buƙatar multimeter tare da thermocouple, kuma a cikin akwati na farko, ma'aunin zafi da sanyio mai iya auna yanayin zafi sama da digiri 100 na Celsius. Idan an duba firikwensin mai kunna fan mai lamba uku, tare da saurin sauyawa guda biyu (wanda aka sanya akan yawancin motocin waje), to yana da kyau a yi amfani da multimeter biyu a lokaci ɗaya. Daya shine duba da'ira daya, na biyu kuma shine a duba da'ira ta biyu lokaci guda. Ma'anar gwajin shine don gano ko an kunna relay lokacin da aka yi zafi zuwa zafin da aka nuna akan firikwensin.

Suna duba firikwensin don kunna fanan sanyaya radiyo bisa ga algorithm mai zuwa (ta amfani da misalin firikwensin fil uku da multimeter ɗaya, da kuma multimeter tare da thermocouple):
