Kodi chivundikiro cha valavu ya galimoto n'chiyani?
Chivundikiro cha valavu yagalimoto ndi gawo la makina, nthawi zambiri limapangidwa ndi zinthu zachitsulo, monga aluminiyamu ndi chitsulo choponyedwa. Chimapezeka pamwamba pa dongosolo la valavu pamwamba pa injini ndipo chimagwiritsidwa ntchito kuphimba zida zoyendetsera valavu ndi valavu kuti zitsimikizire kuti dongosolo la valavu likugwira ntchito bwino. Ntchito yayikulu ya chivundikiro cha valavu ndikuphatikiza kusunga dongosolo la valavu kukhala loyera ndikuletsa zinyalala monga fumbi, dothi, zinyalala kuti zisalowe mu dongosolo la valavu, potero kuteteza zida zoyendetsera valavu ndi mabearing a valavu. Kuphatikiza apo, chivundikiro cha valavu chimaonetsetsa kuti mafuta sakutuluka kapena kulowa mu bearing ya valavu, kupewa kuwonongeka kwa zigawo ndi kutayika kwa mafuta .
Kapangidwe ka chivundikiro cha valavu kakuphatikizapo thupi la valavu, chivundikiro cha valavu, pakati pa valavu, cholongedza, boluti, nati, gasket, chogwirira, chogwirira ndi chipangizo choyendetsera. Thupi la valavu ndiye kapangidwe kake kothandizira, ndipo chivundikiro cha valavu chili pamwamba pa thupi la valavu kuti chitseke ndikugwirizira cholongedza kapena chopopera. Chopopera ndi gawo lowongolera lomwe limayang'anira njira yoyendera, kuthamanga ndi kuyenda kwa madzi. Cholongedzacho chili pakati pa chopopera ndi boluti kuti chitseke ndikuchepetsa kutuluka kwa madzi. Maboluti ndi nati amagwiritsidwa ntchito kulumikiza thupi la valavu ku boluti kuti ligwire pamodzi. Gasket imakhala pakati pa boluti ndi nati ndipo imateteza thupi ndi chipewa kuti zisawonongeke. Chogwiriziracho chimagwiritsidwa ntchito kuyendetsa valavu, chogwiriracho chimathandizira chopopera ndikuchepetsa kukangana, ndipo chipangizo choyendetsera chimagwiritsidwa ntchito kuyendetsa kayendedwe ka spool kuti chikwaniritse ulamuliro wa valavu .
Kusamalira ndi kusintha chivundikiro cha mavavu n'kofunika kwambiri. Kuyang'anira ndi kukonza nthawi zonse kungapewe mavuto omwe amabwera chifukwa cha zipewa za mavavu zotayirira kapena kutseka bwino. Kuyika molakwika kungayambitse kulephera kwa mavavu, zomwe zingakhudze magwiridwe antchito ndi moyo wa injini. Mukasintha bonnet, chinthu ndi kukula komweko monga gawo loyambirira ziyenera kugwiritsidwa ntchito kuti zitsimikizire kuti injini ikugwira ntchito bwino.
Ntchito yaikulu ya chivundikiro cha valve yamagalimoto imaphatikizapo zinthu izi:
Kutseka ndi kuteteza : chivundikiro cha valavu chimagwiritsidwa ntchito kuphimba dongosolo la valavu kuti fumbi, dothi, zinyalala ndi zonyansa zina zisalowe mu valavu, motero kuteteza zigawo zoyendetsera valavu ndi mabearing a valavu, ndikuwonetsetsa kuti ziwalo zamkati mwa injini zili bwino.
Kupaka mafuta ndi kupewa fumbi: Chophimba cha valavu nthawi zambiri chimapanga chotsekedwa ndi ziwalo zonse za injini kuti zitsimikizire kuti mafuta ndi chitetezo cha ziwalo zamkati mwa injini zikugwira ntchito bwino. Kutseka kwake ndikofunikira kwambiri pakugwira ntchito kwabwinobwino kwa injini, mafuta, chitetezo ndi chitetezo cha fumbi.
Sinthani mpweya wopumira wa crankcase: Nthawi zina, chivundikiro cha Valve chilinso ndi Positive Crankcase Ventilation Valve (PCV), yomwe ntchito yake ndikuwongolera kuchuluka kwa utsi wamafuta wopangidwa ndi makina opumira a crankcase kulowa mumakina olowera, ndikudula mpweya wopumira injini ikatentha kuti isalepheretse kulephera monga kuphulika kwa crankcase.
Zosankha za zinthu: Zophimba ma valve nthawi zambiri zimapangidwa ndi zitsulo, zinthu zodziwika bwino zimaphatikizapo aluminiyamu ndi chitsulo chosungunuka. Zophimba ma valve a aluminiyamu ndi zopepuka ndipo zimakhala ndi kutentha kwabwino, pomwe zophimba ma valve achitsulo chosungunuka zimakhala ndi mphamvu komanso kulimba kwambiri.
Malangizo Okonza ndi Kusintha: Zophimba ma valavu zimafunika kuyang'aniridwa ndi kukonzedwa nthawi zonse, makamaka kuti ziwone ngati zimalimba komanso kuti zimayikidwa bwino. Ngati chivundikiro cha valavu chili chomasuka kapena chotsekedwa bwino, zingayambitse kulephera kwa valavu, zomwe zimakhudza magwiridwe antchito ndi moyo wa injini. Mukasintha bonnet, chinthu ndi kukula komweko monga gawo loyambirira ziyenera kugwiritsidwa ntchito kuti zitsimikizire kuti injini ikugwira ntchito bwino.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina pandi tsamba!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
