Ka'idar aiki na haɗin viscous
Haɗin haɗin viscous ya dogara ne akan firikwensin bimetallic wanda yake a gaban fan ɗin viscose. Wannan firikwensin yana faɗaɗa ko kwangila, gwargwadon yanayin zafin da ake watsawa ta hanyar radiator. Wannan ingantaccen bangaren yana inganta ingancin injina ta hanyar daidaita saurin fankar injin da kuma samar da iska mai sanyi.
Yanayin sanyi
Sensor na bimetal yana matse bawul, don haka mai a cikin haɗuwa ya kasance a cikin ɗakin tafki. A wannan lokacin, viscose fan clutch ya rabu kuma ya juya da kusan 20% na saurin injin.
A yanayin zafi mai aiki
Sensor na bimetallic yana faɗaɗa, yana juya bawul din kuma yana barin mai yayi tafiya cikin ɗakin har zuwa gefunan waje. Wannan yana haifar da isasshen karfin juzu'i don fitar da ruwan wukake masu sanyaya a cikin saurin aiki na injin. A wannan gaba, dantse mai ɗaukar fanko yana tsunduma kuma yana juyawa kusan 80% na saurin injin.
Menene iya haɗuwa da haɗuwar viscous zai haifar?
Lokacin maye gurbin famfo, koyaushe ana bada shawara don bincika yanayin fanka mai ɗauke da fan. Haɗaɗɗen haɗuwa kai tsaye zai shafi rayuwar famfo. Kuskuren fanka mai ɗauke da fan na iya zama makale a cikin aikin, wanda ke nufin koyaushe zai yi aiki da kashi 80% na saurin injin. Wannan na iya haifar da lalacewa tare da yawan amo da jijjiga, ƙirƙirar sauti mai kara yayin saurin injin yana ƙaruwa da amfani da mai.
A gefe guda, idan haɗin fanka mai ƙarfi ya gaza a wurin kashewa, ba zai ƙyale iska ta wuce ta cikin radiator ba. Wannan, bi da bi, zai haifar da zafin jiki na injin yayin da aikin sanyaya ya tsaya.
Sanadin gazawar
- Bazuwar mai daga kama, yanke haɗin fan fan;
- Sensin na bimetallic ya yi asarar dukiyar sa saboda aikin sakawan abu a saman, ya sa hannun riga ya makale;
- Malaukewar aiki, kodayake ba safai zai iya faruwa ba idan ba a maye gurbin kama mai ɗaukar fanko bayan dogon nisan miloli ba. Wannan yana haifar da lalacewa a cikin yanayin saman.
Aikin firikwensin viscous
Sensor na bimetallic yana sarrafa aiki na viscose clutch. A farko, akwai nau'ikan tsarin hango bimetallic guda biyu: farantin karfe da murfin wuta. Dukansu suna aiki akan ƙa'ida ɗaya kamar yadda aka bayyana a baya.
Bambanci kawai shine cewa yayin da murfin ke faɗaɗa da kwangila don juya farantin juyawa, kwangilar bimetal da lankwasawa. Wannan yana motsa farantin nunin kuma yana bawa mai damar motsawa daga ɗakin matattarar ruwa zuwa cikin ramin.
Bidiyo: yadda za'a bincika haɗin viscous
Tambayoyi & Amsa:
Ta yaya tuƙi fan viscous ke aiki? An haɗa na'ura mai juyi zuwa mashin crankshaft ta amfani da bel ɗin tuƙi. Ana haɗa faifai tare da impeller zuwa na'ura mai juyi ta ruwa mai aiki. Lokacin da ruwan ya yi zafi, sai ya yi kauri kuma zazzaɓi ya fara gudana zuwa faifan da ke tuƙa.
Yadda za a gane cewa danko na danko ba daidai ba ne? Alamar kuskuren haɗaɗɗiyar danko shine cewa motar tana da zafi fiye da kima kuma fan ɗin baya juyi. A wannan yanayin, gel na iya zubewa, ƙugiya na iya matsewa (ana jin ƙarin sauti).
Mene ne ake amfani da haɗin gwiwar danko? An ƙirƙira haɗin haɗin viscous don haɗa saitin fayafai na ɗan lokaci zuwa saitin jagora. Haɗin kai mai danko na fan mai sanyaya yana ba da sanyaya ga radiyo. Hakanan ana amfani da irin wannan hanyar a cikin motocin tuƙi.
ЧMenene clutch fan na hydraulic? Dangane da yanayin sanyi na injin injin, yana canza saurin fan. Lokacin da ya yi zafi, kama yana ƙara saurin fan.
