Machitidwe a valavu yamoyo.
Udindo wa valavuyo ndiyabwino kwambiri pakulowetsedwa kwa mpweya mu injini ndikutulutsa mpweya wopopera atayaka. Kuchokera pa kapangidwe ka injini, imagawidwa mu valavu yambiri ndi valavu yotha. Udindo wa valve vumba ndikutulutsa mpweya mu injini ndikusakaniza ndi mafuta kuti awotche; Ntchito ya valavu yotulutsa ndikutulutsa mpweya wotuluka pambuyo poyatsa kutentha ndikusungunuka.
Kuphatikizidwa: valavu imapangidwa ndi mutu wa valavu ndi ndodo. Kutentha kwapamwamba kwambiri (kudya kwambiri 570 ~ 670k, valavu ya masitepe, komanso yolimbana ndi mphamvuyo iyenera kukhala ndi mphamvu zina, kuuma, kutentha komanso kuvala kukana. Vesi yopangidwa nthawi zambiri imapangidwa ndi chitsulo chachitsulo (chromium shale, chinsalu cha ma nickel-chromium), ndipo valavu yotulutsa imapangidwa ndi chitsulo chotenthetsera kutentha (silicnon chromium shrode). Nthawi zina kuti asunge chitsulo chotenthetsera, mutu wa valavu yamafuta imapangidwa ndi chilocha chotenthetsera, ndipo ndodo imapangidwa ndi chromium chitsulo, kenako awiriwo amawuzidwa pamodzi.
Maonekedwe a mutu wa valavu imakhala pamwamba, pamwamba kwambiri ndi lipenga pamwamba. Nthawi zambiri pamwamba amagwiritsidwa ntchito. Nthaka yapamwamba kwambiri ili ndi mawonekedwe osavuta, kupangira kosavuta, kuyamwa pang'ono kuyamwa, misa yaying'ono, ndipo imatha kugwiritsidwa ntchito kulowera ku inlet ndi mavumbi. Valavu pamwamba kwambiri ndioyenera valavu yotulutsa, yomwe ili ndi mphamvu yayikulu, kukana kochepa thupi ndi malo abwino otulutsa mafuta, koma ili ndi malo ambiri otentha, akuluakulu akuluakulu ndi njira zovuta. Nyama yamtunduwu ili ndi mizere ina, yomwe imatha kuchepetsa nkhawa, koma mutu wake umayendetsedwa ndi malo akuluakulu, omwe ndi oyenera kuvala bwino.
Ndodo ya Valavu ndi cylindrical, ndikubwezera chitsogozo cha Vallary, ndipo padziko lapansi ziyenera kukhala zoponyedwa. Mawonekedwe a chimaliziro cha valve ndodo zimatengera mawonekedwe okhazikika a Valve, njira yomwe imagwiritsidwa ntchito ndi zidutswa ziwiri zokoka, zina zimakhazikika poyikiratu
Kodi valavu ya injini iyenera kutsukidwa?
M'malo mwake, ziwalo zonse zagalimoto zimakhala ndi kuyeretsa kwagalimoto nthawi zonse, makamaka mugalimoto, injiniyo, ngati sinatsukidwe, kuwonongeka kwa pistorn, ndipo ngakhale pamapeto pake mafuta owotcha injini amafunikira kwambiri. Ndiye kuyeretsa kwa injini, valavu yambiri iyenera kutsukidwa, izi ndikukambirana mwachidule za kutsuka
Kutsuka kwa valavu yazakudya, koyambirira kwa zonse, kumadalira kuchuluka kwa kaboni, ndipo sizachilendo kusonkhana kaboni.
Galimoto nthawi zambiri ili makilomita 40,000, ndikofunikira kulingalira kuyeretsa kwa kaboni kaboni kaboni kaboni kaboni kaboni kaboni. Kenako mwiniyo afunsa momwe angayang'anire mpweya wa injini
Momwe mungayang'anire ngati injini ili ndi kaboni
Njira ndizosavuta. Kukulani chala chanu mu thaulo loyera
Mkati mwa kumapeto kwa chitoliro chopopera, kupaka bwalo lamphamvu, ndikuyang'ana mtundu wa pepala kuti muwone ngati injiniyo ili ndi kaboni.
Njira iyi imatha kudziwa ngati chipinda cha oyaka, piston ndi mphete ya kaboni pa sirlinder injini ndi yovuta kwambiri.
1, Mchira ulibe kaboni: Zala zokutidwa zoyera zoyera, zolimba kuti mupunthe pabwalo, pepala lopepuka lachikaso, losonyeza kuti injini ili mkati mwa kaboni;
2, chitoliro choyamwa choyama champhamvu cha kaboni: Njira yomweyo, yomwe ili ndi bomba lakuda lakuda, lopindika, ntchito ya mphete, yotchedwa carbon yoyandama (yomwe imayikidwa).
3, chitoliro chopopera chopopera: Kugwiritsa ntchito njira yomweyo, kupezeka kuti chitoliro chambirira ndi mpweya wambiri ndi wandiweyani, zomwe zikuwoneka kuti ndizosangalatsa za chopukutira, pomwe panali mpweya wabwino;
4, Mafuta otha mafuta a kaboni: pogwiritsa ntchito njira yomweyo, anapeza kuti pali kaboni wakuda pa pepala loyera la napa loyera, ndipo pali madontho mafuta, zomwe zikuwonetsa kuti injini imayankhidwa.
5, Mafuta Othetsa Mafuta a kaboni kaboni: imatha kutsimikizika kuti chifukwa cha kaboni ndi zifukwa zina, kuvala kwa enginder enger kuli kovuta, kufunikira kwa kukonza akatswiri. Kutsuka pafupipafupi mbali zosiyanasiyana zagalimoto kuli bwino kwagalimoto yokha, komanso kuti akhale ndi chitetezo komanso thanzi. Ngakhale galimoto ili yabwino bwanji, ndikofunikira kusunga galimoto.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga nkhani zina patsamba lino!
Chonde ndiyitane ngati mukufuna zinthu ngati izi.
