Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Pali magawo ambiri mu injini yothamanga kwambiri komanso kulondola kwambiri. Kulondola kwa kuyika kwa magawowa kumakhudzana mwachindunji ndi magwiridwe antchito a injini, ndipo chitsamba chonyamula injini ndi chimodzi mwazinthu zofunika kwambiri.

Ntchito yobereka chitsamba
Chitsamba chonyamula pakati pa khosi la crankshaft spindle ndi mpando wothandizira chimatchedwa chitsamba chachikulu (chitsamba chachikulu), ndipo chitsamba chonyamula pakati pa mapeto aakulu a ndodo yolumikizira ndi crankshaft yolumikizira ndodo imatchedwa chitsamba cholumikizira ndodo (chitsamba chaching'ono). tile). Chitsamba chonyamula chimapangidwa ndi chitsulo chopyapyala chotchinga kumbuyo, ndipo pamwamba pake amaponyedwa ndi wosanjikiza wosamva alloy. Chosanjikiza cha alloy chili ndi mawonekedwe amtundu wofewa, kukana kukangana kochepa komanso kosavuta kuvala. Pali filimu yopaka mafuta pakati pa magazini ndi chitsamba choberekera kuti muchepetse kuvala pamwamba pa zigawo zokwerera.
Injini ikamagwira ntchito bwino, kuchuluka kwa chitsamba chonyamula kumakhala kochepa kwambiri, koma mafuta akamakula mkati mwa injiniyo, kapena kulephera kwamakina, kumayambitsa kuvala kwachilendo kwa chitsamba chonyamula.
Kukhala ndi mawonekedwe a kulephera kwa chitsamba ndi chifukwa
1.Kuwotcha matailosi ogwirizira shaft
Chochitika cholakwika:Kupanda mafuta bwino pakati pa chitsamba chonyamula katundu ndi magazini kumabweretsa kuwonongeka kouma, kutentha kwambiri kwa malo olumikizana kumayambitsa kusungunuka ndi kusungunuka kwa chitsamba, ndipo magaziniyo imatsekedwa, kuti injini isagwire ntchito.
Chifukwa chakulephera:
1. Kukhala ndi chilolezo cha chitsamba ndi chachikulu kwambiri. Kukhala ndi chitsamba chowoneka bwino mpaka pamlingo wina, ndipo kusiyana pakati pa nyuzipepala kumakulirakulira, zomwe zimapangitsa kuti pakhale mpumulo wamafuta komanso filimu yabwino kwambiri yamafuta, kunyamula chitsamba pakati pamafuta sikukwanira.
2.Kutentha kwakukulu. Kuzizira dongosolo kulephera kapena kusowa koziziritsa, chifukwa kwa nthawi yaitali mkulu kutentha injini ntchito, mafuta mamasukidwe akayendedwe kuchepa, sangathe kupanga filimu mafuta pakati pa chitsamba ndi magazini.
3.Kusamalidwa kosayenera. Osasintha mafuta kwa nthawi yayitali, kugwiritsa ntchito mafuta abodza kapena zowonjezera zamafuta, zomwe zimapangitsa kuti chitsamba chisambe chitha kupakidwa.
2.Kutsuka kwa aloyi wosanjikiza
Chochitika cholakwika: kunyamula chitsamba pamwamba yokutidwa ndi odana ndi mikangano aloyi ❖ kuyanika, akhoza kuchepetsa coefficient wa mikangano, kuchepetsa kuvala. Ngati alloy wosanjikiza achotsedwa, kusiyana pakati pa chitsamba chonyamula ndi magazini kumakhala kokulirapo, ndipo pamapeto pake kumabweretsa kulephera kwa matailosi omwe akugwira shaft.
Chifukwa chakulephera:
1.Zimbiri. Pamene mafuta chitsamba chobala, mafuta oxidize ndi dzimbiri aloyi pamwamba pa chitsamba kubala, kuchititsa spalling zitsulo pamwamba pa aloyi wosanjikiza. Ngati mafuta amtundu wabwino agwiritsidwa ntchito, kuwonongeka kwa okosijeni kwa gawo la alloy kumachulukitsidwa.
2.Kutopa kwamafuta. Ngati injini ikuyenda kwa nthawi yayitali pa liwiro lotsika komanso pansi pa katundu wolemetsa, aloyi wosanjikiza wa chitsamba chonyamula amatuluka chifukwa cha kutenthedwa.
3.Kukwapula kuchokera ku zonyansa. Fumbi, zitsulo particles mwachisawawa mafuta mu kubala chitsamba ndi magazini, zikande aloyi wosanjikiza, chifukwa peeling wa aloyi wosanjikiza.
3.Kuvala kwachilendo
Chochitika cholakwika: Pakugwira ntchito kwa injini, mbali zina zosuntha zimalephera, zomwe zimapangitsa kuti chitsamba chisamayende bwino.
Chifukwa chakulephera:
1.Ulalo umapindika. Pazifukwa zina, monga madzi mu combustor, ndodo yolumikizira imapindika chifukwa chakuchulukirachulukira, ndipo pamwamba pa chitsamba cha aloyi wosanjikiza amavala kwambiri chifukwa champhamvu kwambiri.
2.Zovala zophimba zophimba zimakhala zolimba kwambiri kapena zomasuka kwambiri. Kumangirira kwakukulu kapena kocheperako kumatha kupangitsa kuti chitsamba chisayende bwino.
Mfundo zazikuluzikulu zaumisiri wonyamula chitsamba
Ziribe kanthu chomwe chimayambitsa kukonzanso injini, chitsamba chonyamula chimayenera kusinthidwa malinga ndi zofunikira zaukadaulo. Chitsamba chonyamula chitsamba chofananira ndi mtundu wa injini chiyenera kusankhidwa, ndipo mfundo zotsatirazi ziyenera kutsatiridwa pakusonkhanitsa chitsamba chonyamula.
1.Clean chitsamba chonyamula katundu ndi nyumba zokhala kuti zitsimikizire kuti palibe fumbi ndi zonyansa.
2.Kumbuyo kwa chitsamba chonyamulira kumakutidwa ndi mafuta oyera opaka mafuta ndikuyikidwa pampando wonyamula / chophimba. Milomo yoyimilira ya chitsamba chonyamula imafanana ndi poyambira pampando wonyamula ndi chivundikiro. Ngati malo milomo ndi poyambira sizikufanana, kawirikawiri chapamwamba ndi m'munsi mashingles anaika mobwerera.
3.Chivundikiro chonyamulira ndi mpando wonyamulira zimadulidwa pamodzi pa nyuzipepala, ndipo ma bolts okonzekera amamangirizidwa molingana ndi torque yodziwika kuti atsimikizire kuti pakati pa chitsamba chonyamula katundu ndi magazini.
4.Mukayika chitsamba chonyamulira, samalani ngati dzenje la mafuta la chitsamba chonyamulira likugwirizana ndi dzenje la mafuta pampando wonyamula.
