Radiator yamafuta imatchedwanso mafuta ozizira. Ndi chipangizo chozizira mafuta chomwe chimagwiritsidwa ntchito mu injini za dizilo. Malinga ndi njira yozizira, zoziziritsa mafuta zimatha kugawidwa m'madzi ozizira komanso kuziziritsa mpweya.
Nthawi zambiri, mafuta a injini nthawi zambiri amatanthauza dzina lamafuta a injini, mafuta agalimoto (MT) ndi hydraulic transmission oil (AT). Mafuta otumizira ma hydraulic okha amafunikira chozizira chamafuta chakunja (ndiye kuti, radiator yamafuta yomwe mudanena). ) kuti muziziritsa mokakamiza, chifukwa mafuta otumizira ma hydraulic omwe amagwira ntchito pamagetsi odziwikiratu amayenera kugwira ntchito yosinthira ma hydraulic torque, kutumiza ma hydraulic ndi kudzoza ndi kuyeretsa nthawi yomweyo. Kutentha kogwira ntchito kwamafuta otumizira ma hydraulic ndikokwera kwambiri. Ngati utakhazikika, chodabwitsa cha ablation wa kufala akhoza kuchitika, choncho ntchito ya mafuta ozizira mafuta ndi kuziziritsa hydraulic kufala mafuta kuonetsetsa kuti kufala basi akhoza kugwira ntchito bwinobwino.
Mtundu
Malinga ndi njira yozizirira, zoziziritsa mafuta zimatha kugawidwa m'madzi ozizira komanso ozizira mpweya. Kuziziritsa kwamadzi ndikuyambitsa choziziritsa panjira yozizirira injini mu choziziritsa mafuta chomwe chimayikidwa pa transmission yokhayo kuti muziziritse, kapena kuyambitsa mafuta otumizira ma hydraulic m'chipinda cham'munsi chamadzi cha rediyeta ya makina ozizira a injini kuti aziziziritsa; Mafutawa amalowetsedwa mu chozizira chamafuta chomwe chimayikidwa kumbali yakutsogolo kwa grille yakutsogolo kuti aziziziritsa [1].
Ntchito Ntchito ya radiator yamafuta ndikukakamiza mafuta kuti azizizira, kuteteza kutentha kwa mafuta kuti zisapitirire kwambiri ndikuwonjezera kugwiritsa ntchito mafuta, komanso kuteteza mafuta kuti asawonongeke ndi kuwonongeka.
Zolakwa ndi zoyambitsa
Kulephera kofala kwa ma radiator otenthedwa ndi madzi omwe amagwiritsidwa ntchito kumaphatikizira kuphulika kwa chitoliro chamkuwa, ming'alu yakutsogolo / kumbuyo, kuwonongeka kwa gasket, komanso kutsekeka kwa chitoliro chamkuwa. Kulephera kwa kung'ambika kwa chubu chamkuwa ndi ming'alu yakutsogolo ndi yakumbuyo kumayamba makamaka chifukwa cholephera kutulutsa madzi ozizira mkati mwa injini ya dizilo m'nyengo yozizira. Zomwe zili pamwambazi zikawonongeka, padzakhala mafuta m'madzi ozizira ndi madzi ozizira mumafuta mkati mwa poto yamafuta panthawi ya injini ya dizilo. Pamene injini ya dizilo ikugwira ntchito, ngati kupanikizika kwa mafuta kuli kwakukulu kuposa kuthamanga kwa madzi ozizira, mafutawo amalowa m'madzi ozizira kupyolera mu dzenje lapakati, ndipo ndi kayendedwe ka madzi ozizira, mafuta amalowa. chozizirira madzi. Injini ya dizilo ikasiya kuzungulira, madzi ozizira amakhala okwera, ndipo mphamvu yake imakhala yaikulu kuposa mphamvu ya mafuta. Madzi ozizira owopsa amatuluka m'mafuta kudzera pabowo lapakati, ndipo pamapeto pake amalowa mupoto wamafuta. Ngati wogwiritsa ntchito sangapeze vuto lamtunduwu panthawi yake, pamene injini ya dizilo ikupitirizabe kuyenda, mphamvu ya mafuta ya mafuta idzatayika, ndipo pamapeto pake injini ya dizilo idzakhala ndi ngozi monga kuyaka matayala.
Pambuyo pa machubu amkuwa omwe ali mkati mwa radiator atatsekedwa ndi kukula ndi zonyansa, zidzakhudza kutentha kwa mafuta ndi kayendedwe ka mafuta, kotero ziyenera kutsukidwa nthawi zonse.
Kukonzanso
Pakugwira ntchito kwa injini ya dizilo, ngati apezeka kuti madzi ozizira amalowa mu poto yamafuta ndipo pali mafuta mu radiator yamadzi, kulephera kumeneku kumachitika chifukwa cha kuwonongeka kwa pakatikati pa choziziritsa mafuta oziziritsa madzi.
Njira zokonzetsera zenizeni ndi izi:
1. Mutatha kukhetsa mafuta otayika mkati mwa radiator, chotsani mafuta ozizira. Choziziritsa chochotsedwacho chikakonzedwa, lembani choziziritsa kukhosi ndi madzi kudzera mumtsuko wamadzi wamafuta. Pakuyesako, cholowera chamadzi chidatsekeredwa, ndipo mbali inayo idagwiritsa ntchito silinda ya mpweya wothamanga kwambiri kuti ilowetse mkati mwa choziziritsa. Ngati apezeka kuti pali madzi omwe amachokera ku mafuta opangira mafuta ndi kutuluka kwa radiator ya mafuta, zikutanthauza kuti mkati mwa ozizira ozizira kapena mphete yosindikizira ya chivundikiro cham'mbali yawonongeka.
2. Chotsani zophimba zakutsogolo ndi zakumbuyo za radiator yamafuta, ndikutulutsa pachimake. Ngati gawo lakunja la pachimake likupezeka kuti lawonongeka, likhoza kukonzedwa ndi brazing. Ngati chigawo chapakati chapakati chikapezeka kuti chawonongeka, pachimake chatsopano chiyenera kusinthidwa kapena mbali zonse ziwiri za pachimake chimodzi ziyenera kutsekedwa. Pamene chivundikiro cham'mbali chikuphwanyidwa kapena kusweka, chingagwiritsidwe ntchito pambuyo pa kuwotcherera ndi electrode yachitsulo. Ngati gasket yawonongeka kapena yokalamba, iyenera kusinthidwa. Pamene chubu chamkuwa cha rediyeta yamafuta oziziritsidwa ndi mpweya chichotsedwa, nthawi zambiri chimakonzedwa ndi kuwotcha.
