Ntchito ya valavu yolowera.
Ntchito ya valavu ndi yomwe imayang'anira makamaka kulowetsa mpweya mu injini ndikutulutsa mpweya wotuluka ukayaka. Kuchokera ku kapangidwe ka injini, imagawidwa m'magulu awiri: valavu yolowera ndi valavu yotulutsa mpweya. Ntchito ya valavu yolowera ndi kukoka mpweya mu injini ndikusakaniza ndi mafuta kuti uyake; Ntchito ya valavu yotulutsa mpweya ndikutulutsa mpweya wotuluka ukayaka ndikutulutsa kutentha.
Kapangidwe kake: Valavu imapangidwa ndi mutu wa valavu ndi ndodo. Kutentha kwa mutu wa valavu kumakhala kwakukulu kwambiri (valavu yolowera 570 ~ 670K, valavu yotulutsa utsi 1050 ~ 1200K), komanso kupirira kupsinjika kwa mpweya, mphamvu ya kasupe wa valavu ndi mphamvu ya inertia ya gawo lotumizira, mafuta ake, mikhalidwe yoziziritsira ndi yofooka, zomwe zimafuna kuti valavuyo ikhale ndi mphamvu inayake, kuuma, kutentha ndi kukana kuvala. Valavu yolowera nthawi zambiri imapangidwa ndi chitsulo cha alloy (chitsulo cha chromium, chitsulo cha nickel-chromium), ndipo valavu yotulutsa utsi imapangidwa ndi alloy yosatentha (chitsulo cha silicon chromium). Nthawi zina kuti asunge alloy yosatentha, mutu wa valavu yotulutsa utsi umapangidwa ndi alloy yosatentha, ndipo ndodoyo imapangidwa ndi chitsulo cha chromium, kenako ziwirizo zimalumikizidwa pamodzi.
Mawonekedwe a mutu wa valavu ali ndi pamwamba pathyathyathya, pamwamba pa thunthu ndi pamwamba pa nyanga. Nthawi zambiri pamwamba pathyathyathya pamagwiritsidwa ntchito. Mutu wa valavu wathyathyathya uli ndi ubwino wa kapangidwe kosavuta, kapangidwe kosavuta, malo ochepa oyamwa kutentha, kulemera kochepa, ndipo ungagwiritsidwe ntchito pa ma valavu olowera ndi otulutsa. Vavu ya thunthu la valavu ndi yoyenera valavu yotulutsa utsi, yomwe ili ndi mphamvu zambiri, kukana utsi pang'ono komanso mphamvu yabwino yochotsera mpweya wotulutsa utsi, koma ili ndi malo otentha kwambiri, kulemera kwakukulu ndi kusakhala ndi mphamvu, komanso kukonza kovuta. Mtundu wa nyanga uli ndi njira inayake yolumikizirana, yomwe imachepetsa kukana kulowa, koma mutu wake umatenthedwa ndi malo akuluakulu okha, omwe ndi oyenera valavu yolowetsa.
Ndodo ya valavu ndi yozungulira, nthawi zonse imayenda mofanana mu chitsogozo cha valavu, ndipo pamwamba pake payenera kutenthedwa kwambiri ndikupukutidwa. Mawonekedwe a kumapeto kwa ndodo ya valavu amadalira mawonekedwe okhazikika a kasupe wa valavu, kapangidwe kamene kamagwiritsidwa ntchito kwambiri ndi zidutswa ziwiri zokhoma kuti zikhazikitse mpando wa kasupe, kumapeto kwa ndodo ya valavu kuli ndi mpata woyikira chidutswa chokhoma, zina zimakhazikika ndi pini yokhoma, ndipo kumapeto kuli dzenje loyika pini yokhoma
Kodi valavu yolowera injini iyenera kutsukidwa?
Ndipotu, ziwalo zonse za galimoto zimayeretsedwa nthawi zonse, makamaka mtima wa galimoto - ngati injini siitsukidwa, kuchuluka kwa mpweya mkati mwake kungachepetse mphamvu ya injini, kuwonjezera kugwiritsa ntchito mafuta, ndipo nthawi zina zimayambitsa kugwedezeka kwa injini, kufulumizitsa phokoso losazolowereka, kuwonongeka kwa pistoni ndi crankshaft, ndipo pamapeto pake kungayambitse kuwotcha kwa mafuta a injini. Kenako kuyeretsa injini, valavu yolowera iyenera kutsukidwa, apa pali nkhani yayifupi yokhudza kuyeretsa valavu yolowera
Kuyeretsa valavu yolowera, choyamba, kumadalira kuchuluka kwa kaboni komwe kwasungidwa, ndipo ndikwachibadwa kusonkhanitsa kaboni.
Galimoto nthawi zambiri imakhala pamtunda woposa makilomita 40,000, ndikofunikira kuganizira zoyeretsa mpweya woipa, pamene mpweya woipawo ukuwonekera bwino. Kenako mwiniwake adzafunsa momwe angayang'anire kuchuluka kwa mpweya mu injini.
Momwe mungayang'anire ngati injini ili ndi mpweya woipa
Njira yake ndi yosavuta. Manga chala chako mu thaulo loyera la chakudya chamadzulo
Mkati mwa chitoliro chotulutsira utsi, pakani mozungulira mwamphamvu, ndipo yang'anani mtundu wa pepalalo kuti muwone ngati makina a injini ali ndi mpweya woipa.
Njira iyi imatha kudziwa ngati chipinda choyaka moto, pistoni ndi mpweya wa mphete mu silinda ya injini ndi yoopsa kwambiri.
1, chitoliro cha mchira chopanda kaboni: zala zokulungidwa mu zopukutira zoyera, zovuta kupukuta chitoliro cha mchira chopanda kaboni mkati mwa bwalo, pepalalo limakhala lachikasu lopepuka, kusonyeza kuti injini mkati mwake mulibe kaboni;
2, chitoliro chotulutsa mpweya choyandama: njira yomweyi, anapeza kuti chitoliro chotulutsa mpweya chili ndi kaboni wakuda pang'ono, gwirani pang'onopang'ono nsalu yoyera yotsala, silinda ya injini, pisitoni, ntchito ya mphete ndi yachibadwa, pali kuchuluka kwa kaboni woyandama (komwe kumatchedwanso thovu la kaboni, sikunasungidwe).
3, chitoliro chotulutsa mpweya wandiweyani: pogwiritsa ntchito njira yomweyi, anapeza kuti chitoliro chotulutsa mpweya ndi chakuda kwambiri, ndipo chikatha kuphwanyidwa ndi nsalu yoyera, pamakhalabe kaboni wakuda wambiri papepala, zomwe zikusonyeza kuti ndikofunikira kuyeretsa chipinda choyaka moto, pisitoni, mphete ya kaboni;
4, kaboni wa mafuta a payipi yotulutsa utsi: Pogwiritsa ntchito njira yomweyi, adapeza kuti pali kaboni wakuda papepala loyera la nsalu, ndipo pali madontho a mafuta, zomwe zikusonyeza kuti injini ikuwotcha mafuta ndipo ikufunika kukonzedwa.
5, mafuta a chitoliro chotulutsa utsi Utsi wa kaboni: zitha kudziwika kuti chifukwa cha kuchuluka kwa kaboni ndi zifukwa zina, kuwonongeka kwa thupi la silinda ya injini ndi kwakukulu, kufunikira kokonzanso akatswiri. Kuyeretsa nthawi zonse magawo osiyanasiyana a galimoto ndikwabwino pagalimoto yokha, komanso pachitetezo ndi thanzi lawo. Kaya galimotoyo ndi yabwino bwanji, ndikofunikira kusamalira galimotoyo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd.yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zalandiridwakugula.
