Choziziritsira mafuta chimatchedwanso choziziritsira mafuta. Ndi chipangizo choziziritsira mafuta chomwe chimagwiritsidwa ntchito mu injini za dizilo. Malinga ndi njira yozizira, zoziziritsira mafuta zimatha kugawidwa m'zigawo monga kuziziritsa madzi ndi kuziziritsa mpweya.
Kawirikawiri, mafuta a injini nthawi zambiri amatanthauza dzina la mafuta a injini, mafuta a gear ya galimoto (MT) ndi mafuta otumizira ma hydraulic (AT). Mafuta otumizira ma hydraulic okha ndi omwe amafunikira choziziritsira mafuta chakunja (ndiko kuti, choziziritsira mafuta chomwe mwanena).) kuti aziziritse mokakamiza, chifukwa mafuta otumizira ma hydraulic omwe amagwira ntchito mu automatic transmission amafunika kuchita ntchito ya hydraulic torque conversion, hydraulic transmission ndi mafuta odzola komanso kuyeretsa nthawi yomweyo. Kutentha kwa ntchito kwa mafuta otumizira ma hydraulic kumakhala kokwera. Ngati ataziritsidwa, vuto la ablation ya transmission lingachitike, kotero ntchito ya mafuta oziziritsira ndi kuziziritsa mafuta otumizira ma hydraulic kuti atsimikizire kuti automatic transmission ikugwira ntchito bwino.
Mtundu
Malinga ndi njira yoziziritsira, zoziziritsira mafuta zimatha kugawidwa m'magulu oziziritsira madzi ndi oziziritsira mpweya. Kuziziritsa madzi ndi kuyambitsa choziziritsira pa makina oziziritsira injini mu choziziritsira mafuta chomwe chimayikidwa pa makina odziritsira okha kuti chiziziritse, kapena kuyambitsa mafuta otumizira madzi m'chipinda chamadzi chapansi cha radiator ya makina oziziritsira injini kuti chiziziritse; Mafutawo amalowetsedwa mu choziziritsira mafuta chomwe chimayikidwa mbali yakutsogolo ya grille kuti chiziziritse [1].
Ntchito ya radiator yamafuta ndi kukakamiza mafuta kuzizira, kuteteza kutentha kwa mafuta kuti kusakhale kokwera kwambiri komanso kuwonjezera kugwiritsa ntchito mafuta, komanso kuteteza mafuta kuti asawonongeke ndi kuwonongeka.
Zolakwika ndi zomwe zimayambitsa
Kulephera kofala kwa ma radiator amafuta oziziritsidwa ndi madzi omwe amagwiritsidwa ntchito ndi monga kuphulika kwa mapaipi a mkuwa, ming'alu kutsogolo/kumbuyo, kuwonongeka kwa gasket, ndi kutsekeka kwa mkati kwa chitoliro cha mkuwa. Kulephera kwa kuphulika kwa chubu cha mkuwa ndi ming'alu yakutsogolo ndi yakumbuyo kumachitika makamaka chifukwa cha kulephera kwa wogwiritsa ntchito kutulutsa madzi ozizira mkati mwa injini ya dizilo nthawi yozizira. Zinthu zomwe zili pamwambapa zikawonongeka, padzakhala mafuta mu choziziritsira madzi ndi madzi ozizira mu mafuta mkati mwa poto yamafuta panthawi yogwira ntchito ya injini ya dizilo. Injini ya dizilo ikagwira ntchito, ngati kuthamanga kwa mafuta kuli kwakukulu kuposa kuthamanga kwa madzi ozizira, mafutawo amalowa m'madzi ozizira kudzera m'bowo lomwe lili pakati, ndipo madzi ozizira akamayenda, mafutawo amalowa m'choziziritsira madzi. Injini ya dizilo ikasiya kuzungulira, madzi ozizira amakhala okwera, ndipo kuthamanga kwake kumakhala kwakukulu kuposa kuthamanga kwa mafuta. Madzi ozizira oopsa amatuluka m'mafuta kudzera m'bowo lomwe lili pakati, ndipo pamapeto pake amalowa m'poto yamafuta. Ngati woyendetsa galimotoyo sangapeze cholakwika chamtunduwu pakapita nthawi, pamene injini ya dizilo ikupitiriza kugwira ntchito, mphamvu ya mafuta odzola idzatayika, ndipo pamapeto pake injini ya dizilo idzakhala ndi ngozi monga kuyaka matailosi.
Machubu amkuwa omwe ali mkati mwa radiator atatsekedwa ndi sikelo ndi zinyalala, izi zidzakhudza momwe mafuta amatayira kutentha komanso kayendedwe ka mafuta, kotero ayenera kutsukidwa nthawi zonse.
Kukonzanso
Pa nthawi yogwira ntchito ya injini ya dizilo, ngati zapezeka kuti madzi ozizira amalowa mu poto ya mafuta ndipo pali mafuta mu radiator yamadzi, kulephera kumeneku nthawi zambiri kumachitika chifukwa cha kuwonongeka kwa pakati pa choziziritsira mafuta chozizira ndi madzi.
Njira zosamalira zenizeni ndi izi:
1. Mukatulutsa mafuta otayika mkati mwa radiator, chotsani choziziritsira mafuta. Choziziritsira chomwe chachotsedwacho chitafanana, dzazani choziziritsiracho ndi madzi kudzera mu potulukira madzi mu choziziritsira mafuta. Pa nthawi yoyesera, polowera madzi panatsekedwa, ndipo mbali inayo inagwiritsa ntchito silinda ya mpweya wothamanga kwambiri kuti ilowetse mkati mwa choziziritsiracho. Ngati zapezeka kuti pali madzi akutuluka kuchokera mu polowera mafuta ndi potulukira mu radiator ya mafuta, zikutanthauza kuti mkati mwa choziziritsiracho kapena mphete yotsekera ya chivundikiro cham'mbali mwawonongeka.
2. Chotsani zophimba zakutsogolo ndi zakumbuyo za radiator yamafuta, ndikuchotsa pakati. Ngati gawo lakunja la pakati lapezeka kuti lawonongeka, likhoza kukonzedwa pogwiritsa ntchito brazing. Ngati gawo lamkati la pakati lapezeka kuti lawonongeka, pakati patsopano nthawi zambiri payenera kusinthidwa kapena malekezero onse awiri a pakati pamodzi ayenera kutsekedwa. Chivundikiro cham'mbali chikasweka kapena kusweka, chingagwiritsidwe ntchito mutagwiritsa ntchito electrode yachitsulo chopangidwa ndi chitsulo. Ngati gasket yawonongeka kapena yakale, iyenera kusinthidwa. Pamene chubu chamkuwa cha radiator yamafuta yozizira mpweya chachotsedwa, nthawi zambiri chimakonzedwa pogwiritsa ntchito brazing.
