Moyo womwe timawona zida zamakina zitha kukhala zochepa, koma ntchito ya zida zamakina izi ndi yayikulu kwambiri.Monga mayendedwe.Ngati zida zamakinazi ndi zida zamakina zimagwiritsidwa ntchito pafupipafupi, zimakhala zowonongeka kapena zowonongeka, ndipo zikafunika, ziyenera kusinthidwa.Ngati tikufuna kutalikitsa moyo wautumiki wa mayendedwe, pogwiritsidwa ntchito, tiyenera kuwasamalira tsiku ndi tsiku, ndipo gawo loyamba ndikuyeretsa.
Zilowerereni mu palafini kwa mphindi 5-10.Chifukwa chakhala chikugwiritsidwa ntchito kwa nthawi yayitali, poyeretsa kunyamula kwa injini yakale kapena mota yotumizidwa kunja, chogudubuza, chimango cha mkanda ndi mphete yamkati ziyenera kusinthidwa mozungulira kuchokera ku mphete yakunja ndikumizidwa mumafuta otentha.Poyeretsa zodzigudubuza zodzikongoletsera, chodzigudubuza, chimango cha mkanda, mphete yamkati ndi mphete yakunja ziyeneranso kuchotsedwa.Poyeretsa mafuta otentha, kutentha kwamafuta sikuyenera kupitirira 20 ℃.Ngati moto wotseguka umagwiritsidwa ntchito powotchera mwachindunji, chidwi chiyenera kuperekedwa kuti mafuta asatenthedwe.Kunyamula kuyenera kuyimitsidwa mumphika wamafuta ndipo pansi kumayambitsa kutenthedwa ndi kuchepetsa kuuma.
Njira zingapo zopewera dzimbiri
Njira yopangira zinthu zoteteza pamwamba pa dzimbiri:
1) kuyeretsa pamwamba: kuyeretsa kuyenera kutengera momwe zinthu zilili pamwamba pa dzimbiri komanso momwe zinthu ziliri panthawiyo, sankhani njira yoyenera.Nthawi zambiri amagwiritsidwa ntchito poyeretsa zosungunulira, njira yoyeretsera mankhwala ndi makina oyeretsera.
2) Pambuyo pouma ndi kutsukidwa, imatha kuwumitsidwa ndi mpweya wouma wouma, kapena kuumitsa ndi chowumitsira pa 120 ~ 170 ℃, kapena kuumitsa ndi yopyapyala.
Njira yopangira mafuta a antirust
1) Njira yomiza: zinthu zina zing'onozing'ono zimanyowetsedwa mumafuta oletsa kutupa, kotero kuti kumamatira kwapamwamba kwa njira ya antirust mafuta.Makulidwe a filimu amatha kutheka powongolera kutentha kapena kukhuthala kwamafuta oletsa antirust.
2) Njira yokutira burashi imagwiritsidwa ntchito pazida zomangira panja kapena zinthu zapadera zowoneka bwino zomwe sizoyenera kuthira kapena kupopera mbewu mankhwalawa.Chisamaliro chiyenera kuperekedwa osati kupewa kudzikundikira, komanso kupewa kutayikira.
3) Njira yopoperapo Mabomba ena akulu odzigudubuza sangathe kuthiridwa mafuta ndi njira yomiza.Nthawi zambiri, mpweya wosasefedwa ndi kuthamanga kwa pafupifupi 0.7mpa umapopera m'malo oyera.Utsi njira ntchito zosungunulira dilution odana ndi mafuta mafuta kapena woonda wosanjikiza odana ndi mafuta, koma ayenera kugwiritsa ntchito wangwiro moto chitetezo ndi ntchito chitetezo miyeso.
