Kodi cholumikizira ndodo ndi chiyani? Kodi mawonekedwe a injini yolumikizira ndodo yokhala ndi phokoso ndi chiyani?
Chingwe cholumikizira ndodo ndi gawo lomwe limalumikiza pini ya crank, ndipo ntchito yake yayikulu ndikuchepetsa kuvala kwa pini ya crank.
Kumapeto kwakukulu kwa ndodo yolumikizira nsonga nthawi zambiri kumapangidwa padera, kenako kumalumikizidwa ndi tsinde polumikiza ndodo, ndipo mkati mwake nthawi zambiri amaponyedwa alloy antifriction.
Pazinyalala zazikulu zakumapeto popanda ndodo yolumikizira mutu, theka lakumtunda nthawi zambiri limaphatikizidwa ndi tsinde, pomwe chivundikiro chapansi cha theka chimapangidwa mosiyana, kenako chimalumikizidwa ndi theka lakumtunda ndikulumikiza ndodo zolumikizira, ndi mkati mwapamwamba. ndipo magawo apansi a bere ali ndi zida zonyamula.
Pachimake chonyamulira, mkati mwa manja a shaft amabowoleredwa ndi mabowo amafuta, ndipo ma groove ena amafuta amapangidwa kuti aziwongolera mafuta opaka mafuta. Kuphatikiza apo, zodzikongoletsera kapena ndodo zazing'ono zazing'ono nthawi zambiri zimagwiritsidwa ntchito popanga zolumikizira ndodo.
Ntchito ya cholumikizira ndodo ndikuchepetsa kuvala kwa pini, ndipo kukangana pakati pa crank pin ndi shaft kumatha kuchepetsedwa bwino polumikiza pini ya crank ndi shaft, motero kukulitsa moyo wautumiki wa pini.
Panthawi imodzimodziyo, kugwirizanitsa ndodo kungathenso kupititsa patsogolo ntchito ndi mphamvu ya injini, ndi kuchepetsa phokoso ndi kugwedezeka kwa injini. Izi ndichifukwa choti kulumikiza ndodo kumatha kuchepetsa mikangano ndi kuvala mkati mwa injini, potero kumapangitsa kuti injini ikhale yolimba komanso yokhazikika.
Kapangidwe ka mayendedwe olumikizira ndodo nthawi zambiri amaphatikizanso ndodo yolumikizira mipiringidzo yayikulu ndi zolumikizira ndodo, zomwe zolumikizira ndodo zazikulu zimapangidwira padera, ndipo zimbalangondo zazikulu zopanda ndodo zolumikizira zimapangidwira gawo limodzi.
Komanso, kudzikonda kusintha kapena nsanja kulumikiza ndodo fani yaing'ono-mutu nthawi zambiri ntchito dongosolo kulumikiza mayendedwe ndodo kuonetsetsa ntchito yachibadwa ndi bata injini.
Mwachidule, kulumikiza ndodo ndi gawo lofunika kwambiri la injini yamagalimoto, yomwe imatha kuchepetsa kuvala kwa pini ya crank, kukonza magwiridwe antchito ndi mphamvu ya injini, ndikuchepetsa phokoso ndi kugwedezeka kwa injini.
Chifukwa chake, mapangidwe ndi kupanga zolumikizira ndodo ziyenera kukhala zolimba kwambiri kuti zitsimikizire mtundu wawo komanso magwiridwe ake. Popanga magalimoto, zida zapamwamba kwambiri ndi njira zopangira ziyenera kusankhidwa kuti zitsimikizire moyo wautumiki ndi magwiridwe antchito olumikizira ndodo. Panthawi imodzimodziyo, kuyang'anitsitsa nthawi zonse ndi kusintha kwazitsulo zolumikizira ndodo ndi chimodzi mwazinthu zofunika kwambiri kuti zitsimikizire kuti injini ikuyenda bwino.
Phokoso lachilendo la kulumikiza ndodo kumawonekera ngati phokoso losalekeza pamene injini ikukwera kuchokera ku liwiro lopanda ntchito, ndipo kuthamanga kwapamwamba, kumamvekanso kwambiri, zomwe sizikugwirizana ndi kusintha kwa kutentha kwa injini. Pamene kunyamula kumakhala kotayirira kwambiri, padzakhala phokoso lodziwikiratu pa liwiro lachabechabe, phokoso lidzakulitsidwa pamene katunduyo akuwonjezeka, ndipo phokoso lidzachepa kwambiri kapena kutayika pamene moto uchitika.
Njira zothanirana ndi kumveka kwachilendo kwa ndodo zolumikizira ndizo:
1. Kuyesa variable liwiro ndi yamphamvu misfire mayeso, kuphatikizapo auscultation mobwerezabwereza, ngati phokoso kumawonjezeka ndi kuwonjezeka injini liwiro, jitter throttle yomweyo phokoso zachilendo ndi otchuka, ndi kulumikiza ndodo kubala phokoso lachilendo.
2. Pa liwiro lachabechabe, liwiro lapakati komanso kuthamanga kwambiri, kuyesa kwa silinda ndi silinda yamoto, ngati phokoso la silinda likufooka kwambiri kapena kutha pambuyo pa kuzimitsa, ndipo likuwonekera nthawi yomweyo panthawi ya ulamuliro, zikhoza kudziwika kuti kugwirizanitsa ndodo. ya silinda ndi yachilendo.
3. Gwiritsani ntchito stethoscope kapena screwdriver yaitali kwa auscultation, ngati phokoso silikuwonekera, koma phokoso lachilendo pansi pa injini likuwonekera, ndilo phokoso lachilendo la ndodo yolumikizira.
4. Yang'anani kuthamanga kwa mafuta. Ngati phokoso losazolowereka liri lalikulu komanso likutsatizana ndi kutsika kwa mafuta, zikutanthauza kuti chilolezo pakati pa kunyamula ndi magazini ndi chachikulu kwambiri.
Chifukwa cha phokoso lachilendo la kulumikiza ndodo kungakhale chifukwa cha kuloledwa kwakukulu pakati pa chitsamba cholumikizira ndodo ndi magazini ya ndodo yolumikizira, zomwe zimapangitsa kuchepetsa kuuma kwa filimu yamafuta, kuchepa kwa mphamvu yonyamula, kuwonongeka kwa mafuta. , ndi phokoso lachilendo lobwera chifukwa cha kukangana kwa malire kapena kukangana kouma. Zitha kukhalanso kuti msewu waukulu wamafuta wa crankshaft watsekedwa, zosefera ndizonyansa, valavu yodutsa ndi yolakwika, pampu yamafuta ndi yolakwika, ndipo zifukwa zina zimayambitsa kutsika kwamafuta komanso kusapaka bwino kwa chitsamba chonyamula.
Chonde tiyimbireni ngati mukufuna zinthu zotere.
