Kodi chogwirira ndodo cholumikizira ndi chiyani? Kodi phokoso la chogwirira ndodo cholumikizira injini ndi lotani?
Chogwirira ndodo cholumikizira ndi gawo lomwe limalumikiza crank pin, ndipo ntchito yake yayikulu ndikuchepetsa kuwonongeka kwa crank pin.
Chogwirira chachikulu cha ndodo yolumikizira ya crosshead nthawi zambiri chimapangidwa padera, kenako chimalumikizidwa ku shaft ndi mabatani olumikizira ndodo, ndipo pamwamba pake pamkati nthawi zambiri pamakhala chopangira choletsa kupsinjika.
Pa mabearing akuluakulu opanda ndodo yolumikizira mutu wopingasa, theka lapamwamba nthawi zambiri limalumikizidwa ndi shaft, pomwe chivundikiro cha theka lapansi chimapangidwa padera, kenako chimalumikizidwa ndi theka lapamwamba ndi ma bolt olumikizira ndodo, ndipo pamwamba pa theka lapamwamba ndi la pansi la bearing pali bushing yolumikizira.
Pa kapangidwe ka bere, pamwamba pa shaft shelf pamabowoledwa mabowo amafuta, ndipo mipata ina yamafuta imapangidwa kuti ithandize mafuta odzola. Kuphatikiza apo, ma bearing odzisintha okha kapena a platform rod small-head nthawi zambiri amagwiritsidwa ntchito popanga ma bearing olumikizira ndodo.
Ntchito ya chogwirira ndodo cholumikizira ndi kuchepetsa kutopa kwa crank pin, ndipo kukangana pakati pa crank pin ndi shaft kungachepetsedwe bwino polumikiza crank pin ndi shaft, motero kukulitsa moyo wa ntchito ya crank pin.
Nthawi yomweyo, chogwirira ndodo cholumikizira chingawongolerenso magwiridwe antchito ndi magwiridwe antchito a injini, ndikuchepetsa phokoso ndi kugwedezeka kwa injini. Izi zili choncho chifukwa ma bedi a ndodo olumikizira amatha kuchepetsa kukangana ndi kuwonongeka mkati mwa injini, motero kumawonjezera magwiridwe antchito ndi kukhazikika kwa injini.
Kapangidwe ka mabearing a ndodo zolumikizira nthawi zambiri kamakhala ndi mabearing a ndodo yolumikizira mutu wopingasa ndi ma bolt a ndodo zolumikizira, zomwe mabearing a ndodo yolumikizira mutu wopingasa nthawi zambiri amapangidwa padera, ndipo mabearing a ndodo yolumikizira mutu wopingasa amapangidwa m'chinthu chimodzi.
Kuphatikiza apo, ma bearing ang'onoang'ono odzikonzera okha kapena olumikizira ndodo papulatifomu nthawi zambiri amagwiritsidwa ntchito popanga ma bearing a ndodo kuti atsimikizire kuti injini ikugwira ntchito bwino komanso kukhazikika.
Mwachidule, chogwirira ndodo cholumikizira ndi gawo lofunika kwambiri la injini ya galimoto, lomwe lingachepetse kuwonongeka kwa crank pin, kukonza magwiridwe antchito ndi magwiridwe antchito a injini, ndikuchepetsa phokoso ndi kugwedezeka kwa injini.
Chifukwa chake, kapangidwe ndi kupanga ma bearing a ndodo zolumikizira ziyenera kukhala zokhwima kwambiri kuti zitsimikizire kuti zili bwino komanso zikugwira ntchito bwino. Pakupanga magalimoto, zipangizo zapamwamba komanso njira zopangira ziyenera kusankhidwa kuti zitsimikizire kuti ma bearing a ndodo zolumikizira akugwira ntchito bwino komanso kuti zikugwira ntchito bwino. Nthawi yomweyo, kuyang'anira nthawi zonse ndikusintha ma bearing a ndodo zolumikizira ndi chimodzi mwazinthu zofunika kwambiri kuti zitsimikizire kuti injini ikugwira ntchito bwino.
Phokoso losazolowereka la chogwirira cholumikizira ndodo limawonekera ngati phokoso lokhazikika pamene injini ikuthamanga kuchokera pa liwiro lopanda ntchito, ndipo liwiro likakwera, phokoso limakulirakulira, lomwe silikugwirizana ndi kusintha kwa kutentha kwa injini. Chogwirira chikamasuka kwambiri, padzakhala phokoso lodziwikiratu pa liwiro lopanda ntchito, phokoso lidzawonjezeka pamene katundu wawonjezeka, ndipo phokoso lidzachepa kwambiri kapena kuzimiririka pamene moto uyamba.
Njira zothetsera phokoso losazolowereka la ndodo zolumikizira ndi izi:
1. Chitani mayeso osinthasintha a liwiro ndi mayeso olakwika a silinda, kuphatikiza ndi auscultation mobwerezabwereza, ngati phokoso likuwonjezeka ndi kuwonjezeka kwa liwiro la injini, phokoso losazolowereka la jitter throttle limawonekera, ndi phokoso losazolowereka lolumikizana ndi ndodo.
2. Pa liwiro lopanda ntchito, liwiro lapakati komanso liwiro lalikulu, kuyesa moto wa silinda ndi silinda, ngati phokoso la silinda lafooka kwambiri kapena lazimiririka litazimitsidwa, ndipo limawonekera nthawi yomweyo panthawi yoyambiranso, zitha kudziwika kuti cholumikizira ndodo ya silindayo sichili bwino.
3. Gwiritsani ntchito stethoscope kapena screwdriver yayitali kuti mumvetse bwino, ngati phokoso silikumveka bwino, koma phokoso losazolowereka pansi pa injini ndi lodziwikiratu, ndiye kuti phokoso losazolowereka la chogwirira cholumikizira ndodo.
4. Yang'anani kuthamanga kwa mafuta. Ngati phokoso losazolowereka ndi lalikulu komanso kuthamanga kwa mafuta kochepa, zikutanthauza kuti malo pakati pa bearing ndi journal ndi akulu kwambiri.
Chifukwa cha phokoso losazolowereka la chogwirira ndodo cholumikizira chikhoza kukhala chifukwa cha kusiyana kwakukulu pakati pa chitsamba chogwirira ndodo cholumikizira ndi chogwirira ndodo cholumikizira, zomwe zimapangitsa kuti filimu yamafuta ichepe, kuchepa kwa mphamvu yogwirira, kuwonongeka kwa mafuta, komanso phokoso losazolowereka lomwe limayambitsidwa ndi kukangana kwa malire kapena kukangana kouma. Zingakhalenso kuti njira yayikulu yamafuta ya crankshaft yatsekedwa, chophimba chosefera ndi chodetsedwa, valavu yodutsa ndi yolakwika, pampu yamafuta ndi yolakwika, ndi zifukwa zina zimapangitsa kuti mafuta achepe komanso mafuta a chitsamba chogwirira ntchito achepe.
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
