Mai sanyaya fan firikwensin

Yawancin motocin zamani suna sanye da fanka mai amfani da wutar lantarki, wanda ya maye gurbin haɗin gwiwar da ba su da inganci. Na'urar firikwensin fan (fan kunna zafin zafin jiki) yana da alhakin kunna fan, da kuma canza saurin aiki).

Gabaɗaya, firikwensin kunna kunna fan sanyaya:

• abin dogara isa;
• yadda ya kamata sarrafa fan;
• Masu firikwensin fan suna da sauƙin maye gurbin;

A lokaci guda kuma, yana da mahimmanci a gyara ƙarancin aikin wannan na'ura mai sarrafawa, tunda rashin aiki na fan mai sanyaya na iya haifar da zafi fiye da injin. Hakanan kuna buƙatar sanin yadda ake dubawa da maye gurbin firikwensin sauya fan. Kara karantawa a labarinmu.

Ina firikwensin fan

Firikwensin kunna/kashe fan shine na'urar injina ta lantarki don kunnawa da sarrafa aikin fann lantarki mai sanyaya. Ana kunna firikwensin dangane da ma'aunin zafin jiki mai sanyaya. Wannan aikin tunani yana ƙayyade yankin da firikwensin sauya fan yake.

Firikwensin kunna fan na radiyo yana gefen radiyo ko a ɓangarensa na sama (a tsakiya ko a gefe). Saboda wannan dalili, ana kiran wannan firikwensin a matsayin firikwensin heatsink. Don fahimtar ainihin inda firikwensin sauya fan yake, kuna buƙatar nazarin jagorar fasaha daban don takamaiman mota.

Na'urar firikwensin a cikin radiyo yana haifar da zafin jiki na mai sanyaya. Idan ruwan ya yi zafi har zuwa 85-110 digiri Celsius, lambobin sadarwa "kusa" kuma fan ɗin lantarki yana kunna, yana busa motar.

Sakamakon shine ingantaccen zubar da zafi. Bugu da kari, na'urori masu auna firikwensin ba wai kawai kunna fan mai sanyaya ba ne kawai, amma kuma suna iya canza saurin jujjuyawar sa. Idan dumama bai yi girma ba, gudun zai yi ƙasa kaɗan. A babban yanayin zafi, fan yana gudana da cikakken sauri.

Nau'in firikwensin radiyo

A yau a cikin motoci daban-daban zaku iya samun manyan nau'ikan firikwensin kamar haka:

1. Paraffin firikwensin;
2. Bimetallic;
3. Kayan lantarki mara lamba.

Nau'in farko ya dogara ne akan ƙarar hermetic da ke cike da kakin zuma ko wani jiki mai kama da kaddarorin (high coefficient na faɗaɗawa). Maganin Bimetal yana aiki akan tushen farantin bimetal, yayin da hanyoyin da ba a haɗa su ba suna da thermistor.

Bimetallic da paraffin na'urori masu auna firikwensin lamba waɗanda ke rufe da buɗe da'irar fan dangane da zafin jiki na mai sanyaya. Hakanan, firikwensin lantarki ba ya rufe kewaye kuma yana auna zafin jiki kawai, bayan haka yana aika sigina zuwa kwamfutar. Na'urar sarrafawa ta kunna da kashe fan.

Har ila yau, na'urori masu auna firikwensin lamba na iya zama guda ɗaya (ƙungiyar lamba ɗaya) da sauri biyu (ƙungiyoyi biyu) lokacin da saurin fan ke canzawa dangane da zafin jiki.

Misali, firikwensin kunna wuta na VAZ yana aiki a cikin jeri uku: 82 -87 digiri, 87 - 92 digiri da 92 - 99 digiri. A lokaci guda, kasashen waje motoci suna da 4 jeri, babba kofa daga 104 zuwa 110 digiri.

Na'urar firikwensin Radiator

Game da na'urar kanta, tsarinta shine rufaffiyar tagulla ko akwatin tagulla mai mahimmanci a ciki. A waje akwai zare, da kuma na'urar haɗa wutar lantarki. Ana murɗa murfi zuwa radiator ta zoben rufewa a mashigar ruwa mai zafi (kusa da bututun wutar lantarki).

Firikwensin yana cikin hulɗa kai tsaye tare da mai sanyaya. Wasu tsarin suna da na'urori masu auna firikwensin guda biyu a lokaci guda (a mashigar radiyo da kanti) don ƙarin daidaitaccen kulawar sanyaya mai sassauƙa.

Na'urori masu auna firikwensin suna da zaren M22x1,5, da kuma hexagon 29 mm. A lokaci guda, akwai wasu zaɓuɓɓuka inda zaren ya fi ƙanƙanta, M14 ko M16. Dangane da mai haɗa wutar lantarki, wannan haɗin yana bayan firikwensin, amma akwai na'urori masu auna firikwensin inda mai haɗin ke keɓancewar kebul ɗin.

Yadda ake duba firikwensin fan da maye gurbinsa

Idan fan bai kunna cikin lokaci ba ko kuma injin yana yin zafi koyaushe, ya zama dole don bincika firikwensin radiyo. Ana iya bincika firikwensin tuntuɓar da hannuwanku a cikin gareji na yau da kullun.

Lura cewa abu na farko da za a bincika ba shine firikwensin kanta ba, amma mai sanyaya fan relay da wayoyi. Don yin wannan, kuna buƙatar cire haɗin wayoyin firikwensin kuma ku gajarta su. Idan akwai wayoyi 3, muna rufe tsakiya kuma mu ƙare bi da bi. A al'ada, fan ya kamata ya kunna a duka ƙananan gudu da sauri. Idan ya haskaka, to, wayoyi da relay na al'ada ne kuma kana buƙatar duba firikwensin.

Don bincika, ɗauki akwati na sanyaya, maɓalli don cire firikwensin da ma'aunin zafi da sanyio, sannan za ku buƙaci multimeter, tukunyar ruwa da murhu.

1. Bayan haka, an cire tashar baturi, an cire magudanar magudanar ruwa kuma an zubar da ruwa;
2. Bayan zubar da ruwa, filogi ya dawo baya, an cire firikwensin firikwensin, bayan haka dole ne a kwance firikwensin tare da maɓalli;

6. Idan lambobin sadarwa ba su rufe ko kuma an lura da lahani, firikwensin ya yi kuskure kuma yana buƙatar maye gurbinsa.

Amma game da maye gurbin firikwensin fan, gabaɗayan tsarin yana saukowa don buɗe tsohuwar firikwensin da zazzagewa cikin sabon. Hakanan yana da mahimmanci don maye gurbin gasket (O-ring).

Na gaba, kuna buƙatar duba matakin maganin daskarewa, ƙara ruwa idan ya cancanta kuma duba aikin tsarin (dumi injin kuma jira fan ya kunna).
