Kodi chivundikiro cha valve ndi chiyani?
Chophimba cha valve ndi mbale yophimba yomwe imagwiritsidwa ntchito kuteteza camshaft pamwamba pa chipinda cha valve ndikupanga chimbudzi chotsekedwa ndi mutu wa silinda (palinso ndime zobwereranso mafuta, ndime zoperekera mafuta ndi ndime zina zamafuta zomwe zimagwirizanitsidwa ndi ma cavities ena)
Kodi chomwe chimayambitsa kutayikira kwa mpweya mu chophimba cha valve ndi chiyani?
Kutuluka kwa mpweya kuchokera pachivundikiro cha valve kumapangitsa galimotoyo kulephera kuyendetsa. Ngati chisakanizocho chili cholemera kwambiri kapena chochepa kwambiri, mafuta omwe ali mu chipinda choyaka moto samatenthedwa kwathunthu, zomwe zimapangitsa kuti mafuta achuluke. Zidzapangitsanso kuti galimotoyo ifulumire pang'onopang'ono. Injini ndizovuta kuyambitsa, mphamvu imachepa, kuyaka sikukwanira, gawo la kaboni ndi lalikulu, ndipo ngakhale masilinda amunthu sangagwire ntchito. Nthawi zambiri, ngati pali kutayikira kwamafuta, tikulimbikitsidwa kuti musinthe chivundikiro cha valve
Kodi zilibe kanthu ngati chivundikiro cha valve chimatulutsa mafuta?
Chivundikiro cha valve gasket chimatulutsa mafuta, omwe amakhudzabe galimotoyo. Iyenera kusinthidwa pakapita nthawi. Chivundikiro cha valve gasket chimagwiritsidwa ntchito kwambiri kusindikiza kuti mafuta asatayike. Ngati sichidzasinthidwa panthawi yake, chisindikizocho chidzachepa, kuuma, kutaya mphamvu komanso kusweka kwambiri. Ngati ndikungotuluka kwa mafuta chifukwa cha kukalamba kwa mutu wa silinda ya valve, vutoli likhoza kuthetsedwa mwa kusintha mutu wa silinda ya valve ndi yatsopano. Mukagula nokha, mtengo wake ndi pafupifupi 100 yuan. Mukapita ku sitolo ya 4S kuti mulowe m'malo mwake, zikhala zosachepera 200 yuan. Chivundikiro cha valavu nthawi zambiri chimapangidwa ndi mphira, ndipo chimodzi mwazinthu zazikulu za mphira ndikukalamba. Choncho, ngati moyo wautumiki wa galimotoyo ndi wautali kwambiri, zinthu za rabara zimakalamba ndi kuuma, zomwe zimapangitsa kuti mafuta azituluka. Posintha, tcherani khutu ku mfundo zotsatirazi. Mukasintha, yeretsani kwathunthu kukhudzana. Ikani guluu ngati mungathe, chifukwa zimatenga nthawi yayitali kuti mugwiritse ntchito guluu. Ndibwino kuti musagwiritse ntchito guluu. Zimatengera zofuna za mwiniwake. 2. Injini iyenera kukhazikika kwathunthu isanathe kusinthidwa. 3. Mukayika chivundikiro cha valve, limbitsani kangapo diagonally. Mukamaliza kukonza wononga, bwererani ku phula la diagonal. Izi zidzateteza kupsinjika kosagwirizana pa chivundikiro cha valve gasket.
Kodi chivundikiro cha valve chikuwoneka choyipa bwanji?
Nthawi zambiri pamakhala zifukwa zingapo zowonongeka kwa valve chivundikiro cha gasket. Choyamba ndi chakuti bolt ndi lotayirira, lachiwiri ndi injini yowomba, lachitatu ndi kuphulika kwa chivundikiro cha valve, ndipo chachinayi ndi chakuti chivundikiro cha valve gasket chawonongeka kapena chosatsekedwa ndi sealant.
Panthawi ya kukanikizana kwa injini, mpweya wochepa umayenda kuchokera pakhoma la silinda ndi mphete ya pistoni kupita ku crankcase, ndipo kuthamanga kwa crankcase kumakwera pakapita nthawi. Panthawiyi, valavu ya crankcase ventilation imagwiritsidwa ntchito kutsogolera gawo ili la gasi kumalo ambiri olowera ndikuyamwa mu chipinda choyaka kuti chigwiritsidwenso ntchito. Ngati valavu ya crankcase ventilation yatsekedwa, kapena chilolezo pakati pa mphete ya pisitoni ndi khoma la silinda ndi yayikulu kwambiri, zomwe zimapangitsa kuti mpweya uziyenda kwambiri komanso kuthamanga kwambiri kwa crankcase, mpweyawo umatuluka m'malo osasindikiza ofooka, monga chivundikiro cha valve gasket. , zosindikizira zamafuta a crankshaft kutsogolo ndi kumbuyo, zomwe zimapangitsa kuti injini itayike.
Malingana ngati mumagwiritsa ntchito chosindikizira, sungani ma bolts, ndipo chivundikiro cha valve sichikuphwanyidwa kapena kusokoneza, chimasonyeza kuti chivundikiro cha valve ndi chabwino. Ngati simuli omasuka, mutha kugwiritsa ntchito chowongolera ndi choyezera makulidwe (feeler gauge) kuyeza kusalala kwa chivundikiro cha valve kuti muwone ngati sichikupunduka.
