Chodulira Burashi cha Petroli cha Mphamvu ya Injini cha 2 Stroke

Pakugwiritsa ntchito chodulira burashi, mavuto osiyanasiyana angabuke, ndipo pali njira zosiyanasiyana zothetsera vuto lililonse. Tiyenera kupereka mankhwala oyenera kuti tipewe mavuto akuluakulu. Lero, tikambirana za zifukwa zomwe zimapangitsa chodulira burashi kukoka silinda, zomwe zimayambitsa phokoso lamphamvu poyambitsa ndi kuyimitsa, komanso zifukwa zomwe chodulira burashi chimagwedezeka kapena kugwedezeka mwamphamvu panthawi yogwira ntchito.

Kodi ndi zinthu ziti zomwe zimayambitsa kukoka masilinda mu makina othirira?

Kukoka silinda kunganenedwe kuti ndi vuto lalikulu komanso lofala kwambiri pa injini ya makina odulira. Pali zifukwa zambiri zomwe zingayambitse vutoli, ndipo chofunikira kwambiri ndi mafuta a injini. Ndikofunikira kusunga kuyera ndi kusamala kwa mafuta a injini kuti pistoni iyende bwino mu silinda pansi pa mafuta a injini. Mafuta a injini auve, ochulukirapo, kapena osakwanira angayambitse mafuta osayenera komanso kukoka silinda. Kuyang'ana mafuta a injini musanagwiritse ntchito ndikofunikira kwambiri pamakina odulira.

Zizindikiro za zolakwika:

Malo olumikizirana pakati pa crankshaft ndi ndodo yolumikizira amamatira, ndipo pali zizindikiro za kukakamira pamalo olumikizirana pakati pa ndodo yolumikizira ndi crankshaft.

Chifukwa cha vuto:

Kusawonjezera mafuta odzola (mafuta a injini ya petulo), kapena kuwonjezera mafuta odzola koma osati pamalo pake, kapena kuwonjezera mafuta odzola koma osati pamalo pake koma makinawo amagwiritsidwa ntchito pa ngodya yosayenera, zomwe zimapangitsa kuti mafuta azithira ndipo gudumu lisakhudze mafutawo, zomwe zimapangitsa kuti pamwamba pa crankshaft ndi ndodo yolumikizira pasakhale mafuta odzola kapena kusowa kwa mafuta odzola, zomwe zimapangitsa kuti mafuta azizire komanso azizire. Nthawi zambiri, pa liwiro logwira ntchito, mkati mwa mphindi zochepa, crankshaft ndi ndodo yolumikizira zitha kuluma chifukwa cha zifukwa zomwe zili pamwambapa, zomwe zimapangitsa kuti ndodo yolumikizira isweke ndikuswa silinda.

Kuphatikiza apo, kuwonjezera mafuta a injini abodza komanso otsika mtengo kungayambitsenso mavuto omwe atchulidwa pamwambapa.

Maziko a kusanthula:

1. Mainjini onse oyaka mkati, crankshaft ndi kutsekeka kwa ndodo yolumikizira (kapena kutseka) kumachitika chifukwa cha kusowa kwa mafuta;

2. Nthawi zina, ngati mafuta osungidwa mu makina owonongeka ndi wogwiritsa ntchito alibe zizindikiro za zinyalala, zimasonyeza kuti palibe mafuta panthawi yogwira ntchito kapena kuchuluka kwa mafuta kuli kochepa kwambiri kuti gudumu lothira madzi lifike, kapena mafuta omwe ali mu makinawo adawonjezedwa pambuyo pa ngozi, ndipo mafuta omwe adawonjezedwa pambuyo pa ngozi sanalowe nawo mu mafuta, kotero akadali oyera komanso opanda zinyalala (mafutawo ndi akuda a imvi);

3. Palinso vuto pamene, ngakhale pali mafuta okwanira, kugwiritsa ntchito malo otsetsereka opitirira madigiri 25 kungayambitse mafuta kuphulika ndipo mawilo sangathe kufika pa mafuta, zomwe zimapangitsa kuti zolakwika zomwe zatchulidwa pamwambapa kapena kukoka kwa zigawo zina (kapena kutseka), kuwonongeke mwachangu.

N’chifukwa chiyani phokoso lalikulu limakhalapo poyambitsa ndi kuyimitsa makina othirira?

Chifukwa cha vuto lomwe latchulidwa pamwambapa ndichakuti boti yomwe ili pakati pa tsamba silinamangidwe. Ngati injini yalephera kugwira ntchito, maboti ayenera kuchotsedwa, cholumikiziracho chiyenera kuchotsedwa, kuyang'aniridwa ngati chawonongeka, kenako cholumikiziracho ndi tsamba ziyenera kubwezeretsedwanso, ndipo maboti ayenera kumangidwanso.

Kodi chifukwa chake chodulira burashi chimagwedezeka kapena kugwedezeka mwamphamvu ndi chiyani panthawi yogwira ntchito?

Ngati chodulira burashi chikukumana ndi kugwedezeka kapena kugwedezeka kwambiri panthawi yogwira ntchito, izi zitha kukhala chifukwa cha kugunda zinthu zolimba panthawi yodula, zomwe zimapangitsa kuti tsamba lizipindika ndikusokonekera, zomwe zingayambitse kuti chodulira burashi chigwedezeke. Kuphatikiza apo, kupukusa tsambalo kukhala lolemera pamwamba komanso pansi kungayambitsenso kuti chodulira burashi chigwedezeke. Chifukwa chake, ndikofunikira kupukusa masamba a chodulira burashi kukhala mopingasa mbali zonse ziwiri. Mukamagwiritsa ntchito, muyenera kuyang'ana momwe udzu ulili ndipo zinthu zolimba ziyenera kupewedwa momwe zingathere.

Kukoka silinda ya chodulira burashi ndi chimodzi mwa zinthu zomwe zimavuta kwambiri kwa odulira burashi. Ndikofunikira kulemba anthu odziwa bwino ntchito yokonza burashi kuti ayang'ane ndikukonza burashi iliyonse isanayambe kudula, kuti athe kuchitapo kanthu. Zinthu zazikulu zokonza ndi monga kutsuka carburetor, kutsuka mpweya woipa womwe uli m'chipinda choyaka moto, kuwona ngati dera lamagetsi amphamvu silikutsekedwa, komanso ngati bokosi la gear likugwira ntchito bwino.
