Zoyenera kuchita ngati chotsukira cha unyolo chili chofooka | Njira yokonzera mpweya wotuluka mu chotsukira cha unyolo
Kutulukira kwa macheka a unyolo kukugwiritsidwa ntchito m'malo ambiri, oyenera kudula nthambi za mitengo m'nkhalango zozimitsa moto, kukonza malo m'mizinda, misewu ikuluikulu, udzu ndi minda ya maluwa, minda ya zipatso zaulimi, misewu, zipatala, masukulu, m'malo okhala ndi nyumba zambiri, m'mapaki, ndi zina zotero. Mabanja ambiri akuyamba kugwiritsa ntchito macheka a unyolo, koma ogula akukumana ndi vuto, lomwe ndi loti achite ngati macheka a unyolo alephera kugwira ntchito. Lero, mkonzi adzalankhula za kukonza macheka a unyolo.
1, Kodi tingathetse bwanji vuto la kusanja kwa unyolo kukhala kofooka?
Ngati chotsukira cha unyolo sichili champhamvu mokwanira, mutha kuyang'ana silinda ndi kabureta ndikuchepetsa liwiro la kabureta.
1. Tsegulani loko yotetezera ndikukoka baffle yomwe ili patsogolo pa chogwirira kubwerera ku malo ogwirira. Mukamva phokoso la "click", limatseguka. Mosiyana ndi zimenezi, kukankhira patsogolo kudzatseka unyolo, ndipo unyolo wa throttle sudzasuntha kwambiri injini ikakwera.
2. Kupingasa kwa mano a unyolo ndi kosiyana ndi kwa mano a sprocket, ndipo sangathe kuzungulira ngakhale ataluma mano.
3. Mano a unyolo ndi chitsulo chowongolera ndi zolimba kwambiri ndipo zimamatira. Kodi mungathe kukoka unyolo ndi dzanja mutachotsa mbale yowongolera ndi unyolo kuchokera ku Koripu chainsaw ndikuyiyika pa mbale yowongolera?
2, Kodi vuto ndi chiyani kuti chainsaw isayambe?
(1) Bwerekani, kokani pedali ya breki mmbuyo mwamphamvu ndipo galimotoyo imayima. Kokani chotchinga chakutsogolo pansi kupita ku thupi la munthuyo ndi mtendere wamumtima.
(2) Unyolo ndi wothina kwambiri ndipo uyenera kusinthidwa. Kodi mungathe kukoka unyolo ndi dzanja ngati uli wothina kwambiri poyamba? Ngati sungathe kukokedwa, masulani unyolo pang'ono.
(3) Vuto la gudumu la unyolo, kodi ndi chifukwa cha kusowa kwa mafuta mu unyolo? Onjezani mafuta ena kuti mupaka mafuta musanayambe. Unyolo ndi mbale yotsogolera sizimapaka mafuta opaka, ndipo pakakhala zovuta kwambiri, zimatha kutsekeka. Ngati vuto lotere lichitikanso mutawonjezera mafuta opaka, ndi nthawi yoti musinthe sprocket.
3, Kodi mungachite chiyani ngati chotsukira unyolo chikutulutsa mpweya?
Pali mitundu iwiri ya mpweya wotuluka mu macheka a unyolo. Chimodzi sichili chachikulu. Liwiro la injini ya macheka a unyolo limawonjezeka akayamba kugwira ntchito, zomwe zimapangitsa kuti phokoso likhale lolimba komanso losalekeza. Macheka a unyolo amayenda mofulumira kwambiri pa throttle yochepa, ndipo kusintha mafuta a carburetor sikuthandiza. Podula nkhuni, kuwonjezera throttle kumapangitsa kuti macheka a unyolo aime.
Chifukwa china n’chakuti pamene chainsaw ikutulutsa mpweya kwambiri, injini imalephera ndipo singathe kuyambikanso, kapena chainsaw imayenda mofulumira kwa kanthawi injini isanayime nthawi yomweyo. Ngati mpweya ukutuluka mu crankcase si woopsa kwambiri, pamene pistoni ikukwera mmwamba, kusiyana kwa kuthamanga mkati mwa crankcase kumachepa, ndipo chisakanizo cholowa mu crankcase ndi silinda chimakhala choonda kwambiri. Silindayo imakhala ndi mpweya wambiri ndipo imayaka mofulumira itayatsidwa. Komabe, kuthamanga kwa mpweya pamwamba pa pistoni ikayaka kumakhala kochepa. Zotsatira zake, pamene katundu wawonjezeredwa (kudula matabwa), mafuta ochapira, ndi injini zimazimitsa chifukwa cha mphamvu zosakwanira.
Ngati crankcase ituluka kwambiri, kupanikizika mkati mwa bokosilo kumakhala kofanana ndi kupsinjika kwa mpweya, ndipo chainsaw singathe kuyatsidwa. Dziwani mwachangu ndikuchotsa kutayikira mu crankcase. Pali kutayikira kwakukulu mu crankcase komwe nthawi zambiri sikuoneka ndi maso. Mwachizolowezi, timagwiritsa ntchito njira yopumira utsi kuti tiwone malo otayikira mu crankshaft, zomwe ndi zosavuta kwambiri.
Mukayang'ana, chotsani bokosi la gearbox ndi flywheel ya chainsaw, kankhirani pistoni pakati pa pamwamba, ikani spark plug, pumirani utsi wambiri ndi pakamwa panu, ndikukonza chainsaw. Gwiritsani ntchito dzanja lanu kuti muthandizire dzenje lotulutsa utsi ndikuwuzira mwamphamvu ku dzenje lolowera, kuti mudziwe malo otayikira ndi osuta. Njira yowunikirayi ndi yachangu komanso yolondola. Ngati palibe kutuluka kwa mpweya mu crankcase mutawuzira utsi mobwerezabwereza, izi zimachitika chifukwa cha kulumikizidwa kosasunthika kwa carburetor ndi cylinder air inlet, ndipo zomangira zomangira pa fitting zitha kumangidwa. Izi zitha kuthetsa vuto la kutuluka kwa mpweya mu chainsaw crankcase!
