Kodi valavu ya valavu ndi iti?
Chophimba cha valavu ndi mbale yophimba yomwe imagwiritsidwa ntchito kuteteza camshaft pamwamba pa chipinda cha valavu ya valavu ya valavu yotseka ndi mitu yopendekera, mavesi ena amafuta olumikizidwa ndi ma caving ena ogwirizana)
Kodi choyambitsa mpweya chikuyenda ndi chiyani?
Kutulutsa kwa mpweya kuchokera ku chivundikiro kumapangitsa kuti galimoto ithe kuyendetsa. Ngati osakaniza ndi olemera kwambiri kapena owonda kwambiri, mafuta m'chipinda choyaka sichinawotchedwa kwathunthu, ndikugwiritsa ntchito mafuta ochulukirapo. Zipangitsanso galimoto kuti ifulumize pang'onopang'ono. Injiniyi ndi yovuta kuyamba, mphamvu imachepa, kuphatikiza sikokwanira, kaboni ka kaboni ndi yofunika kwambiri, ndipo ngakhale olinda payekha sangagwire ntchito. Nthawi zambiri, ngati pali kutayikira kwamafuta, ndikulimbikitsidwa kuti musinthe valavu
Kodi zili ndi kanthu kuti valavu yophimba mafuta imadumphira mafuta?
Valavu pachikuto cha galket imadumphira mafuta, omwe amakhudzabe galimoto. Iyenera kusinthidwa nthawi. Valavu pachikuto cha gasket imagwiritsidwa ntchito kusindikizidwa kuti tipewe kutaya mafuta. Ngati sichisinthidwa pakapita nthawi, Chisindikizo chidzazirala, kuumitsa, kutaya thupi komanso ngakhale kusweka kwambiri. Ngati ndi kutayika kwamafuta chifukwa cha ukalamba wa mutu wa Valive Varlinder, vutoli limatha kusinthidwa ndikusinthanitsa mutu wa Varlive ndi watsopano. Ngati mungagule nokha, mtengo wake ndi pafupifupi 100 yuan. Ngati mupita ku malo osungira 4s kuti musinthe, kudzakhala 200 yuan. Valavu kuphimba gasket nthawi zambiri imapangidwa ndi mphira, ndipo imodzi mwamitundu yayikulu ya mphira ndikukalamba. Chifukwa chake, ngati moyo wagalimoto uli kalekale, zinthu za mphira zidzakalamba ndi kuumitsa, zomwe zimayambitsa mafuta. Mukasinthanitsa, samalani ndi mfundo zotsatirazi. Polowetsa, yeretsani kwathunthu. Tsatani guluu ngati mungathe, chifukwa zimatenga nthawi yayitali kuti mugwiritse ntchito guluu. Palibe vuto kuti mugwiritse ntchito guluu. Zimatengera zofuna za mwini. 2. Injiniyo iyenera kukhazikika kwathunthu isanathe m'malo. 3. Mukakhazikitsa chivundikiro cha valavu, ndikulimbana kangapo. Pambuyo pokonzekera screw, bwererani ku screw. Izi zimalepheretsa kupsinjika mosagwirizana ndi valavu yophimba gasket.
Kodi valavu imawoneka bwanji yoyipa?
Pali zifukwa zingapo zowonongeka za valavu yophimba mafuta. Choyamba ndichakuti botilo ndi lotayirira, lachiwiri ndi injini ya injini, yachitatu ndi yophimba kwambiri, ndipo chachinayi ndichakuti valavu ya Valve imawonongeka kapena osakutidwa ndi sealant.
Panthawi ya complen stroke wa injini, gasi laling'ono kwambiri limayenda pakhoma la cylinder ndi mphete ya piston kupita ku crankcase, ndipo kupsinjika kwa crankcase kumatha nthawi. Pakadali pano, valavu yamkaka yamkati imagwiritsidwa ntchito kutsogolera gawo ili la mafuta kuzomwe zimafalikira ndi kuyamwa mu chipinda chophatikiza kuti mugwiritsenso ntchito. Ngati valavu yamadzi yotsekemera imatsekedwa, kapena chilolezo pakati pa piston mphete ya piston ndi lalikulu kwambiri, mpweya wowoneka bwino, womwe umatulutsa mafuta am'mafuta.
Malingana ngati mungagwiritse ntchito zosindikiza, ndikulimba ma bolts, ndipo chivundikiro cha valavu sichimasweka kapena chopunduka, chikuwonetsa kuti chivundikiro cha valavu ndiyabwino. Ngati mulibe chiyembekezo, mutha kugwiritsa ntchito wolamulira komanso gaudege (gauger ya zoumba) kuti muyeze khungu la valavu kuti muwone ngati sizingasinthe.
