Mzere Wapamwamba wa Valavu ya Galimoto: Woyang'anira Wosaoneka Akutsimikizira Kusalala kwa Injini
Mu njira yolondola yogwiritsira ntchito injini ya galimoto, mzati wapamwamba wa valavu ndi chinthu chooneka ngati chosafunika koma chofunikira kwambiri. Uli ngati mlonda wodzipereka, nthawi zonse kuonetsetsa kuti makina a valavu ya injini akugwira ntchito molondola. Komabe, ikalephera kugwira ntchito bwino, imayambitsa mavuto ambiri pa ntchito yanthawi zonse ya injini.
Ntchito yaikulu ya valavu ya galimoto
Mzati wapamwamba wa valavu ya galimoto umagawidwa m'mitundu iwiri: ya hydraulic ndi ya makina. Pakati pawo, mzati wapamwamba wa valavu ya hydraulic, wokhala ndi ubwino wake wapadera, umagwiritsidwa ntchito kwambiri mu injini zamakono zamagalimoto.
Ntchito yaikulu ya hydraulic valve top column ili pakulipira yokha kuti valavu ichotsedwe. Panthawi yogwira ntchito ya injini, njira yotumizira valavu imapanga valavu yochotsera chifukwa cha kutentha ndi kuwonongeka. Kuchotsera kumeneku sikungowonjezera phokoso la injini komanso kumakhudza mpweya woipa wa valavu, motero kuchepetsa mphamvu ndi mafuta a injini. Valve top column ya hydraulic valve ingagwiritse ntchito mphamvu ya mafuta odzola injini kuti isinthe kutalika kwake, kuchepetsa valavu yochotsera, kuonetsetsa kuti valavu ndi camshaft nthawi zonse zimakhala ndi malo olumikizirana opanda mipata, kusunga valavu yogwirira ntchito bwino ndikuwonetsetsa kuti injini ikugwira ntchito bwino komanso moyenera.
Kuphatikiza apo, mzati wapamwamba wa hydraulic valve ukhoza kuchepetsa bwino phokoso la injini. Mzati wapamwamba wa valavu yamakina wamba umafuna kusintha kwa valavu nthawi zonse pamanja. Mzati ukakula kwambiri, injini imapanga phokoso lomveka bwino panthawi yogwira ntchito. Komabe, mzati wapamwamba wa valavu ya hydraulic umachotsa valavu yokha, kuchepetsa kupanga phokoso lotere kuchokera muzu, ndikupanga malo opanda phokoso mkati mwa okwera.
Ngakhale kuti mipiringidzo ya ma valve amakina siili ndi ntchito yosintha yokha malo olowera, imatengabe udindo wofunikira wotumiza mphamvu kuchokera ku camshaft ndikuyendetsa valavu kuti itsegule ndi kutseka. Ndi gawo lofunika kwambiri pa makina a valavu.
Zizindikiro ndi zomwe zimayambitsa kulephera kwa valavu pamwamba pa mizati
Pamene valavu ya pamwamba yalephera, injini nthawi zambiri imatulutsa "zizindikiro zochenjeza" zoonekeratu, zomwe nthawi zambiri zimakhala phokoso losazolowereka.
Phokoso losazolowereka lomwe limayambitsidwa ndi hydraulic valve top column lili ndi zizindikiro zina: nthawi zambiri, panthawi yogwira ntchito ya injini yopanda ntchito, phokoso losamveka bwino limatuluka kuchokera pamwamba pa chivundikiro cha silinda, chomwe chimawonekera makamaka m'malo ozizira a injini. Pamene liwiro la injini likuwonjezeka kapena galimoto ikuyenda mofulumira kwambiri, phokosolo lidzachepa pang'onopang'ono kapena kutha. Phokosoli limayamba chifukwa cha zifukwa zotsatirazi: Choyamba, vuto la mafuta a injini. Ngati mafuta a injini ali okwera kwambiri kapena otsika kwambiri, kapena kuthamanga kwa mafuta sikukwanira, hydraulic valve top column sidzalandira mafuta okwanira opaka. Mpweya wakunja udzatenga mwayi wolowa mkati mwa hydraulic column, kusokoneza hydraulic balance yake, motero kupanga phokoso. Kuphatikiza apo, kugwiritsa ntchito mafuta abodza kapena owonongeka a injini kudzawonjezera kuwonongeka kwa valvu top column, zomwe zimapangitsa kuti ilephereke. Chachiwiri, kuwonongeka kwa zigawo. Pamwamba pa plunger padzawonongeka pakapita nthawi, ndipo chisindikizo cha valvu ndi chofooka, zomwe zimapangitsa kuti mafuta atuluke. Izi zidzakhudza ntchito yachizolowezi ya hydraulic valve top column, zomwe zimalepheretsa kusintha bwino valvu, ndikupanga phokoso. Chachitatu, kuipitsidwa kwa mafuta. Ngati mzati ndi thupi la mzati wapamwamba zatsekedwa ndi madontho a mafuta ndi zinyalala, izi zidzalepheretsa kuyenda bwino kwa mafuta a injini, zomwe zimapangitsa kuti mzati wapamwamba wa valavu usakhale ndi mafuta okwanira komanso ukhale wosagwira ntchito bwino.
Kupatula phokoso losazolowereka, kulephera kwa valavu pamwamba pa injini kungakhudzenso magwiridwe antchito a mphamvu ya injini. Ngati kutayika kwa valavu sikungathe kulipidwa bwino chifukwa cha kulephera kwa valavu pamwamba pa injini, nthawi yotsegulira ndi kutseka valavu imasinthasintha, zomwe zimakhudza kusalala kwa kulowa ndi kutuluka kwa mpweya, zomwe zimapangitsa kuti mphamvu ya injini ichepe komanso kuchuluka kwa mafuta omwe amagwiritsidwa ntchito. Pazochitika zazikulu, ngakhale valavu imatha kulephera kutseka bwino, zomwe zimapangitsa kuti silinda ituluke, zomwe zimawononga injini kwambiri.
Yankho ndi kupewa kulephera kwa valavu pamwamba pa mizati
Injini ikatulutsa phokoso losazolowereka lomwe likuganiziridwa kuti lachitika chifukwa cha kulephera kwa valavu pamwamba pa valavu, mwiniwakeyo ayenera kuchitapo kanthu kuti alifufuze ndikulithetsa pa nthawi yake. Gawo loyamba ndikuwona kuchuluka kwa mafuta a injini ndi mtundu wake. Ngati kuchuluka kwa mafuta kuli kochepa kwambiri, onjezerani mafuta a injini oyenera pakapita nthawi. Ngati mafuta awonongeka, m'malo mwake ndi mafuta atsopano. Ngati pali zolakwika zomwe zimachitika chifukwa cha kuwonongeka kwa zigawo kapena kutayikira kwa mafuta, ma pistoni, ma valve ndi zina zomwe zawonongeka kwambiri ziyenera kusinthidwa pakapita nthawi kuti zitsimikizire kuti valavu pamwamba pa valavu ikugwira ntchito bwino.
Pakugwiritsa ntchito galimoto tsiku ndi tsiku, kupewa zolakwika za valavu pamwamba pa galimoto ndikofunikiranso. Eni ake ayenera kutsatira mosamalitsa zofunikira za buku lowongolera galimoto, kusintha mafuta a injini ndi fyuluta yamafuta nthawi zonse, ndikugwiritsa ntchito mafuta apamwamba a injini omwe amagulidwa kuchokera ku njira zovomerezeka kuti apewe kuwonongeka kwa valavu pamwamba pa galimoto chifukwa cha mavuto amafuta. Nthawi yomweyo, yesetsani kupewa kusokoneza injini kwa nthawi yayitali ndikuchepetsa chiopsezo cha kupsinjika kwambiri kwa valavu pamwamba pa galimoto. Kuphatikiza apo, fufuzani injini nthawi zonse kuti mudziwe ndikuthetsa mavuto omwe angakhalepo, zomwe ndizofunikira kwambiri pakuwonjezera moyo wa valavu pamwamba pa galimoto ndikuwonetsetsa kuti injini ikugwira ntchito bwino.
Ngakhale kuti valavu ya pamwamba pa galimoto ndi yaying'ono, imagwira ntchito yofunika kwambiri pakugwira ntchito kwa injini. Kumvetsetsa ntchito yake, kudziwa bwino zizindikiro zake zolakwika, komanso kudziwa njira zoyenera zoyankhira ndi njira zopewera ndikofunikira kuti chitetezo chosawonekachi chigwire bwino ntchito ndikuteteza kuti injiniyo isagwire bwino ntchito.
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 MG&MAXUSzida zamagalimoto zalandiridwa kugula.
