Kukhazikitsa radiator ya galimoto: "Woyang'anira kutentha" kwa injini
Cholumikizira choziziritsira cha galimoto ndicho chigawo chachikulu cha makina oziziritsira injini omwe amazizira ndi madzi ndipo chingaonedwe ngati "choteteza kutentha" cha injini. Chimapangidwa makamaka ndi pakati pa choziziritsira, fani, cholepheretsa mphepo, zipinda zamadzi zapamwamba ndi zapansi, ndi mapaipi olumikizira. Kudzera mu kusinthana kwa kutentha pakati pa choziziritsira ndi mpweya, chimawongolera bwino kutentha kwa injini, ndikuwonetsetsa kuti nthawi zonse imakhala mkati mwa mulingo woyenera wa ntchito wa 85°C - 95°C.
Injini ikagwira ntchito, 30% - 40% yokha ya kutentha komwe kumapangidwa ndi kuyaka kwa mafuta imasandulika mphamvu, ndipo yotsalayo imafunika kutayidwa kudzera mu makina oziziritsira. Mfundo yogwirira ntchito ya radiator ili ngati fakitale yosinthira kutentha yogwira ntchito bwino: Choziziritsira chimayendetsedwa ndi pampu yamadzi kupita ku jekete lamadzi la injini, chimayamwa kutentha kuchokera ku silinda block ndi mutu wa silinda, kenako chimadutsa mu chitoliro chapamwamba kupita ku radiator core. Panthawiyi, fan imazungulira kuti iyendetse mpweya mofulumira kwambiri kudzera mu radiator core, ndipo kutentha komwe kumatengedwa ndi coolant kumatulutsidwa mumlengalenga. Choziziritsira chozizira chimabwerera kudzera mu chitoliro chapansi kupita ku pampu yamadzi, ndikumaliza kuzungulira. Panthawiyi, machubu amkuwa ndi zipsepse za radiator core zimakulitsa malo osinthira kutentha, ndipo fan ndi wind deflector zimawongolera njira yoyendera mpweya, kuonetsetsa kuti kutentha kumataya bwino.
Kuwonjezera pa ntchito yoyambira yochotsa kutentha, cholumikizira cha radiator chimagwiranso ntchito zofunika kwambiri. Chingathe kuletsa kukula ndi kusintha kwa zigawo za injini komanso kuchepa kwa kukhuthala kwa mafuta a injini chifukwa cha kutentha kwambiri, zomwe zimapangitsa kuti moyo wa injini ukhale wautali; mwa kusunga kutentha kokhazikika, kumathandizira kuyaka bwino kwa mafuta ndikuchepetsa kutulutsa utsi; ma radiator a mitundu ina amaphatikizanso ntchito zosungira madzi, kupereka malo osungira oziziritsira okhazikika komanso kupewa kuwonongeka kwa mphamvu yozizira chifukwa cha kuchuluka kwa madzi.
Chenjezo la cholakwika: "Chizindikiro cha thanzi" cha gulu la radiator
Ngakhale kuti cholumikizira cha radiator chili ndi kapangidwe kolimba, chingakumanebe ndi zolakwika chikakumana ndi kutentha kwambiri komanso kupsinjika kwakukulu kwa nthawi yayitali. Kumvetsetsa mawonekedwe wamba a zolakwikazi kungathandize eni magalimoto kuzindikira mavuto pakapita nthawi ndikupewa kuwonongeka kwa injini.
Kutentha kwambiri kwa injini
Ichi ndi chizindikiro chodziwikiratu cha vuto la kusonkhana kwa radiator. Pamene pakati pa radiator patsekeka, fani imasiya kuzungulira, kapena choziziritsira chimatuluka, kutentha sikungathe kuzimiririka bwino, ndipo kutentha kwa injini kudzakwera kwambiri. Kuwala kowunikira pa dashboard kudzaloza mwachangu kudera loopsa lofiira, ndipo ngakhale "kuwira" kungachitike. Ngati sikukonzedwa pasadakhale, kungayambitse kulephera kwakukulu kwa makina monga kumamatira kwa piston ndi kusintha kwa mutu wa silinda.
Kutayikira kwa choziziritsira
Gasket yotsekera ya zipinda zamadzi zapamwamba ndi zapansi pa radiator imakalamba, chubu chapakati chimawononga ndi kubowola, kapena payipi yolumikizira imasweka. Izi zimapangitsa kuti choziziritsira chituluke. Eni ake amatha kudziwa izi poona ngati pali madontho amadzi obiriwira kapena pinki pansi kapena kuwona ngati kuchuluka kwa madzi mu thanki yokulirapo kumatsika mofulumira. Kutayikira kwa choziziritsira sikumangokhudza kutentha komwe kumataya komanso kungayambitsenso kuti pampu yamadzi iziyenda mosalekeza chifukwa cha kuchuluka kwa madzi ochepa, zomwe zimapangitsa kuti zinthu ziwonongeke.
Fan yozizira yosadziwika bwino
Fani yoziziritsira ndi gawo lofunika kwambiri pakupanga radiator. Zolakwika zake zimaonekera makamaka ngati sizikuzungulira, liwiro lotsika, kapena phokoso losazolowereka. Mafani amagetsi amatha kuchitika chifukwa cha masensa otenthetsera omwe awonongeka, kulephera kwa relay, kapena ma mota oyaka; ma clutch a fan a silicone oil amalephera, zomwe zimapangitsa fan kuti isasinthe liwiro lake lozungulira lokha malinga ndi kutentha. Kugwira ntchito kwa fan kosazolowereka kumabweretsa kuchepa kwa mphamvu yotaya kutentha, makamaka panthawi yoyendetsa galimoto yopanda mphamvu kapena yothamanga pang'ono, pomwe chiopsezo cha kutentha kwambiri kwa injini chimawonjezeka kwambiri.
Kutaya mphamvu ndi kuchuluka kwa mafuta omwe amagwiritsidwa ntchito
Ngati mphamvu yoziziritsira ya radiator siili yokwanira, injini imakhala pamalo otentha kwambiri kwa nthawi yayitali, zomwe zimapangitsa kuti mphamvu yoyaka ichepe, mafuta a injini achepe, komanso zinthu monga mphamvu yofooka komanso kuthamanga pang'onopang'ono. Nthawi yomweyo, kuti kompyuta igwire bwino ntchito, idzawonjezera mphamvu yopangira mafuta, zomwe zimapangitsa kuti mafuta agwiritsidwe ntchito molakwika.
Kuzindikira zolakwika ndi kukonza tsiku ndi tsiku
Akakumana ndi zolakwika pakupanga ma radiator, eni magalimoto amatha kuzindikira vutolo pongothetsa mavuto mosavuta. Ngati injini yatentha kwambiri, choyamba ayenera kuyang'ana mulingo wa coolant. Ngati sikokwanira, onjezani mtundu womwewo wa coolant ndikuwona. Ngati mulingo uli wabwinobwino, onani ngati fani ikugwira ntchito ndipo ngati pamwamba pa radiator padzaza fumbi kapena fluff ya msondodzi. Kuti coolant ituluke, injini ikazizira, mutha kuyang'ana mapaipi ndi chipinda chamadzi m'maso kuti muwone ngati pali zizindikiro zilizonse zotayikira, kapena gwiritsani ntchito choyesera kuthamanga kuti muwone momwe makinawo akutsekera.
Kukonza nthawi zonse ndi chinsinsi chowonjezera nthawi yogwira ntchito ya radiator. Ndikofunikira kuyang'ana mulingo ndi khalidwe la coolant kamodzi pa miyezi itatu iliyonse kapena makilomita 5,000, kuonetsetsa kuti ili mkati mwa sikelo ya MAX-MIN komanso yopanda kukhuthala kapena kusintha mtundu; yeretsani zinyalala pamwamba pa radiator kamodzi pachaka, ndikugwiritsa ntchito mpweya wothamanga kwambiri kuti upume kuchokera kumbuyo kupita kutsogolo kuti musawononge zipsepse za radiator; sinthani coolant zaka ziwiri zilizonse kuti mupewe dzimbiri lamkati lomwe limayambitsidwa ndi kuwonongeka kwa coolant; nthawi yomweyo, yang'anani nthawi zonse mphamvu ya lamba wa fan ndi momwe fan imagwirira ntchito, ndikukonza zolakwika zilizonse pakapita nthawi.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
