Zofunikira pakukhazikitsa malamulo okhwima okhudza kutulutsa magalimoto komanso kugwiritsa ntchito mafuta kwapangitsa kuti bizinesi yonse yamagalimoto ivutike kuti ikwaniritse izi.Pofuna kuchepetsa kugwiritsa ntchito mafuta komanso kutulutsa mpweya, njira yachikhalidwe yakhala yochepetsera kulemera kwagalimoto.Chifukwa chake chotchinga cha aluminium alloy cylinder block m'malo mwa chitsulo chosungunuka chasintha kukhala njira yachitukuko.Kuphatikiza apo, kuyaka kwa injini kumatha kusinthidwa modabwitsa pochepetsa kukangana mkati mwa injini.Chifukwa chake ukadaulo watsopano wa injini yamagalimoto ya "cylinder Liner less" wakopa chidwi cha opanga magalimoto ambiri.
Ukadaulo wocheperako wa injini zamagalimoto zidatheka poyambitsa ukadaulo wopopera mbewu mankhwalawa.Kugwiritsa ntchito kupopera mbewu mankhwalawa kumachitika panthawi yopangira injini.Kupopera ndi ntchito pamwamba pa pretreated aluminiyamu injini yamphamvu bores.Utsiwu umawonjezera nsanjika yosamva ya zokutira zokhala ndi mpweya wochepa kuti zilowe m'malo mwa silinda yachitsulo yachikhalidwe.Kukonzekera kwa midadada ya silinda popanda zomangira kumaphatikizapo zigawo zotsatirazi ndikugwiritsa ntchito:
● kuponya
● kukonza mwaukali chipika cha silinda
● kutumiza mameseji m'mwamba mwa silinda
● kutentha pamwamba
● kupopera mbewu mankhwalawa kutentha
● kumaliza makina
● kumaliza kukonza
Njira zazikuluzikulu zaukadaulo waukadaulo wocheperako wa silinda zimachitikira pamalo a coaxial (ma cylinders awiri omwe mawonekedwe awo a cylindrical amakhala ndi mizere yomwe imadutsa mabwalo ozungulira mu ndege yomwe yapatsidwa ndipo imakhala yolumikizana ndi ndege iyi) ndi kukwapula kwa silinda.Izi zimakwaniritsidwa ndi:
Cholinga cha pamwamba roughening chofunika kuonjezera pamwamba pa malo kupanga pamwamba dongosolo kuti amalola ❖ kuyanika kuti umakaniko womangidwa pamwamba pa gawo lapansi, kuonjezera mawotchi kuluma mphamvu ya ❖ kuyanika kwa gawo lapansi ndi kupitiriza yambitsa ndi kulimbikitsa pamwamba. Mphamvu zomangira zakuthupi.Kuwotcha pamwamba kumachitika m'njira zosiyanasiyana, monga kuphulitsa grit, kuwononga makina, komanso kuwotcha kwamadzi othamanga kwambiri.Kuphulika kwa grit ndi njira yomwe imagwiritsidwa ntchito kwambiri popangira zitsulo zonse.
Pamwamba pazitsulo zimatha kutsukidwa, kukhwinyazidwa ndikukhala zotakasuka pambuyo pa kuphulika kwa mchenga.Pamwamba pake amatsukidwa ndi mpweya wouma wopanda mafuta musanagwiritse ntchito kupopera mbewu mankhwalawa.
Kukantha (Surface Activation) kungathenso kuchitidwa pogwiritsa ntchito makina.Ndipo pali njira zomwe aluminiyamu pamwamba pake amapangidwa kukhala mizere ina.Izi zimachitika pogwiritsa ntchito malo opangira makina amtundu umodzi komanso kugwiritsa ntchito zida zodulira.Uku ndikukonza kamodzi kuti mutsirize mawonekedwewo m'njira yotsika mtengo.Pankhani ya silinda yachitsulo yonyezimira kwambiri, zida zachitsulo zonyezimira kwambiri zidapangidwa nthawi zambiri zomwe zimapangitsa izi kukhala zosavomerezeka.
Kuwotcha kwa jet kwamadzi othamanga kwambiri kumangogwiritsidwa ntchito pa silinda ya aluminiyamu ndipo sikugwira ntchito ndi silinda yachitsulo chonyezimira.Njira yopangira jet yamadzi sigwiritsa ntchito ma abrasives okwera mtengo.Komabe kugwiritsa ntchito mwachindunji kwa jet yamadzimadzi pamtunda wapansi panthaka kumatheka kokha pamene pamwamba pauma.Ndipo ngakhale pamenepo pamwamba roughness mtengo ndi otsika poyerekeza ndi njira zina.
Kuwumitsa pamwamba ngati njira yofunika kwambiri muukadaulo wopanda silinda kumakhudza mwachindunji mphamvu zomangira ndi zokutira za zokutira.Chifukwa chake, ndikofunikira kulabadira njira yowumitsa pamwamba pakugwiritsa ntchito ukadaulo wa cylinder less cylinder block.Kusankha njira yoyenera roughing n'kofunika kwambiri kuti akwaniritse bwino kutsegula pamwamba ndi bwino kupanga.
