Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Kukonza galimoto, imodzi mwa mbali zofunika kwambiri za injini. Ntchito yofunika kwambiri yokonza magalimoto ndikusintha mafuta. Eni ake ambiri sangadziwe momwe mafuta amakhudzira. Chifukwa chiyani kusintha mafuta? Kodi ndi bwino kusasintha?
●Kodi mafuta a injini amatani?
Mafuta m'kamwa mwathu kwenikweni ndi mtundu wa mafuta injini. Galimotoyo ikayambika, mbali zonse za galimotoyo zimayamba kugwira ntchito kenako n’kusudzulana nthawi zonse. Panthawi imeneyi, mafuta amatha kugwira ntchito yabwino poteteza ziwalozo. Osati zokhazo, ilinso ndi ntchito zotsatirazi:
01) Antifriction yamafuta
Pali wachibale wothamanga pakati pa pisitoni ndi silinda, pakati pa spindle ndi chitsamba chonyamula, kuteteza mbalizo kuti zisavale mofulumira kwambiri, m'pofunika kukhazikitsa filimu yamafuta pakati pa malo awiri otsetsereka.
Filimu yamafuta yokhala ndi makulidwe okwanira imalekanitsa mawonekedwe a magawo omwe akuyenda molumikizana, potero amachepetsa kuvala.
02) Kuzizira
Mafutawa amanyamula kutentha kuthanki ndikukatulutsa mumpweya kuti thanki iziziritse injini.
03) Sambani bwino
Mafuta abwino akhoza kubweretsa carbide, sludge ndi kuvala zitsulo particles pa injini mbali kubwerera ku thanki kudzera kufalitsidwa, ndi kutsuka dothi opangidwa pa ntchito pamwamba mbali mwa otaya mafuta mafuta.
04) Sindikizani umboni wotsikira
Mafuta amatha kupanga mphete yosindikizira pakati pa mphete ya pistoni ndi pisitoni, kuchepetsa kutuluka kwa gasi ndikuletsa kulowa kwa zonyansa kuchokera kunja.
05) Dzimbiri
Mafuta opaka mafuta amatha kuyamwa pamwamba pa zigawozo kuti ateteze madzi, mpweya, asidi ndi mpweya woipa kuti usagwirizane ndi ziwalozo.
06）Kuyamwa modzidzimutsa
Pamene mphamvu ya injini ya silinda pakamwa ikukwera kwambiri, katundu pa pisitoni, zinyalala za pisitoni, ndodo yolumikizira ndi crankshaft yonyamula ndi yayikulu kwambiri, ndipo katunduyo amathiridwa mafuta ndi kufalikira kwa chotengeracho, kotero kuti katunduyo amanyamula kusungitsa.
●N'chifukwa chiyani ndikufunika kusintha mafuta?
01) Choyamba,mafuta adzagwiritsidwa ntchito mochulukira, nthawi zina tidzakumana ndi nthawi yokonza mafuta asanatenthe kapena osakwanira, izi zimadziwika kuti "mafuta oyaka".
02) Chachiwiri,mafuta adzaipitsidwa, zotsalira zoyaka mafuta pakhoma la silinda zidzakankhidwira mumafuta, ndipo zinyalala zazing'ono zomwe zimapangidwa ndi kuvala kwa ziwalozo zidzasakanizidwanso mumafuta, zomwe zimapangitsa kuti mafutawo azigwiritsidwa ntchito kwambiri. Mafuta okhala ndi zonyansa zambiri samangokhala amachepetsa chitetezo pazigawo, komanso amakhala ndi zowonongeka zina.
03) Pomaliza,mafutawo alinso ndi moyo, ngakhale galimoto sikuyenda, mafuta pang'onopang'ono oxidize ndi kuwonongeka, kutaya zotsatira za mafuta, ndi kutaya chitetezo cha galimoto.
●Kodi chimachitika ndi chiyani ngati simusintha mafuta kwa nthawi yayitali?
01）40000 Km
Injini yomwe yayenda makilomita 40,000 popanda kusintha mafuta imakhala ndi matope akuda omwe amamangiriridwa ku khoma lamkati la silinda.
02）75000 Km
Injini yokhala ndi mafuta opitilira 75,000 mailosi mkati ndi kunja kwa injiniyo imakhala ndi grime wandiweyani womwe pafupifupi umadzaza danga kunja kwa magawo osuntha mkati mwa silinda.
Kodi injini iyi ikugwirabe ntchito?
Yankho ndi inde, koma mumatha kumva kuti phokosolo silinali bwino, ndipo mphamvu yotulutsa mphamvu imatsika kwambiri.
03）150000 Km
Ndiwo ma 150,000 mailosi oyendetsa popanda kusintha mafuta.
Mafuta a injini oyenerera ayenera kukhala ndi luso loyeretsa bwino, koma chifukwa mafuta amangowonjezeredwa kwa nthawi yaitali, zomwe zimapangitsa kuti pakhale matope ambiri ndi zonyansa mkati mwa injini.
Mofanana ndi injini yautali wa makilomita 75,000 pamwamba pake, mkati mwa silindayo muli chisokonezo.
●Kodi mumadziwa bwanji ngati galimoto yanu ikufunika kusintha mafuta?
Galimoto ikafunika kusintha mafuta, kuwonjezera pa kuyang'ana nthawi yokhazikika ndi mtunda, mutha kuweruzanso kuchokera pazikhalidwe zitatu zotsatirazi.
01) Munthawi yoyamba,kutengera mtundu wa injini, pali mitundu iwiri pamsika, imodzi ndi yodzipangira yokha ndipo ina ndi turbo. Ma turbines amafunikira kwambiri pamtundu wamafuta. Ambiri, turbine injini ayenera kusintha mafuta pasadakhale pa makilomita 8000. Ngati ndi injini yodzipangira yokha, mutha kupita kumtunda wopitilira makilomita 10,000 kuti musinthe mafuta onse opangira.
02) Mtundu wachiwiri wa zinthu,akhoza kuweruzidwa molingana ndi chilengedwe cha galimoto, nthawi zambiri kudutsa dziko kapena kutenga msewu ndi mchenga wambiri ndi fumbi, zidzachititsa kuti mafuta awonongeke, monga kuchepetsa chiyero, kugwiritsa ntchito mopitirira muyeso kumayambitsa kuwonongeka kwa injini.
Choncho pamenepa, tikulimbikitsidwanso kusintha mafuta pafupipafupi. Poyendetsa makilomita zikwi zisanu kapena zisanu ndi chimodzi, m'pofunika kuyang'ana mlingo wa adhesion wa mafuta, ndipo m'malo mwake, ngati ukuwonongeka.
03) Njira yachitatu ndikuyang'ana nthawi.Kawirikawiri galimoto imayendetsa pang'ono, choncho nthawi yowerengera ndi yabwino kwambiri.
Musaganize kuti galimoto anatsegula atatu kapena anayi makilomita zikwi, safuna m'malo, bola ngati nthawi ikufunika kusintha, apo ayi mafuta akhoza kuwonongeka.
