Kodi Pampu Yozizira Yamagetsi ndi chiyani?

Pampu yamagetsi yamagetsi yagalimoto imangokhala pampu yamadzi: njira yamagetsi yomwe imayendetsa antifreeze yagalimoto kuchokera ku injini kupita ku tanki yamadzi.Pampu yamadzi yathyoka, antifreeze sakuzungulira, injini iyenera kuyendetsedwa, ndipo kutentha kwa madzi kumakhala kwakukulu, zomwe zingakhudze silinda ya injini.

Ntchito ya pampu yamadzi yoziziritsa pagalimoto

Pampu yamadzi yagalimoto imatchedwanso pampu yamagetsi yamagetsi yagalimoto.Chinsinsi cha mpope wamadzi agalimoto ndi gawo lofunikira pakuyendetsa mokakamizidwa kwa makina oziziritsa magalimoto.Pulley ya injini imayendetsa kunyamula ndi choyikapo cha mpope wamadzi kuthamanga, ndipo antifreeze mu mpope wamadzi imayendetsedwa ndi impeller kuti izungulira, ndipo imaponyedwa m'mphepete mwa chipolopolo cha mpope wamadzi pansi pa mphamvu ya centrifugal, ndipo panthawi imodzimodziyo imayambitsa kuthamanga kofunikira, ndiyeno imatuluka kuchokera kumadzi kapena chitoliro cha madzi.Pamene antifreeze ikuponyedwa kunja, kuthamanga kwapakati pa chopondera kumatsika, ndipo antifreeze mu thanki yamadzi imayamwa mu chopopera kudzera mu chitoliro cha madzi pansi pa kusiyana kwapakati pakati pa kulowetsa kwa mpope ndi pakati pa chopondera kuti chilowetse. zindikirani kubwereza kobwerezabwereza kwa antifreeze.

Pamene galimoto ikuyendetsa, onjezerani antifreeze pamtunda wa makilomita 56,000 aliwonse, ndipo idzawonjezedwa ka 2 kapena 3 motsatizana, ndipo m'malo mwake idzasinthidwa ndikukayikira kuti pali kutayikira.Popeza injiniyo ndi yotentha, imapukuta madziwo.Pazochitika zachilendo, zimakhala zovuta kuzindikira kutuluka kwa mpope wamadzi kumayambiriro, koma n'zotheka kuzindikira mosamala ngati pali madontho a madzi pansi pa mpope.Nthawi zonse, moyo wautumiki wa mpope wamadzi wagalimoto ukhoza kukhala pafupifupi makilomita 200,000.

Pali njira yamadzi yoziziritsira madzi mu silinda ya injini yagalimoto, yomwe imalumikizidwa ndi radiator (yomwe imadziwika kuti thanki yamadzi) yomwe imayikidwa kutsogolo kwa galimotoyo kudzera papaipi yamadzi kuti apange njira yayikulu yoyendetsera madzi.Pamalo otulutsira madzi apamwamba a injini, mpope wamadzi umayikidwa, woyendetsedwa ndi lamba wa fan, kupopera madzi otentha mumsewu wamadzi wa silinda ya injini, ndikupopera m'madzi ozizira.Palinso thermostat pafupi ndi mpope wamadzi.Galimotoyo ikangoyambika (galimoto yozizira), sichiyatsidwa, kotero kuti madzi ozizira amangozungulira mu injini popanda kudutsa mu thanki yamadzi (yomwe imadziwika kuti kuyendayenda kochepa).Pamene kutentha kwa injini kufika pamwamba pa madigiri 80, imayatsidwa, ndipo madzi otentha mu injini amaponyedwa mu thanki yamadzi.Galimotoyo ikamapita kutsogolo, mpweya wozizira umadutsa mu thanki yamadzi kuti uchotse kutentha, zomwe zimagwira ntchito motere.

Mwachidule, ndi mpope wamadzi: njira yamagetsi yomwe imayendetsa antifreeze yagalimoto kuchokera ku injini kupita ku tanki yamadzi.Pampu yamadzi yathyoka, antifreeze sazungulira, injini iyenera kuyendetsedwa, ndipo kutentha kwa madzi kumakhala kwakukulu, zomwe zingakhudze silinda ya injini, yomwe imakhala yovuta.Choncho, ndi bwino kuti madalaivala azikhala ndi chizoloŵezi choyang’ana chida cha galimoto pamene akuyendetsa, mofanana ndi kuchuluka kwa mafuta amene atsala.
