Izvo zvinodikanwa zvekushandisa zvakanyanya kuomesesa zviyero pakuburitswa kwemotokari uye kushandiswa kwemafuta zvakonzera kuti indasitiri yese yemotokari imhanyire kusangana nekuvandudzwa uku.Kuti uderedze kushandiswa kwemafuta uye kubuda kwemhepo, nzira yechinyakare yave yekudzikisa huremu hwemotokari.Saka iyo aluminium alloy cylinder block panzvimbo yesimbi yakakandwa yashanduka kuita maitiro ebudiriro.Pamusoro pezvo, kugona kupisa kweinjini kunogona kuvandudzwa zvinoshamisa nekudzikisa kukweshera mukati meinjini.Naizvozvo tekinoroji nyowani yemotokari ye "cylinder Liner shoma" yakwezva kutarisisa kwevazhinji vanogadzira mota.
Injini yemotokari (s) cylinder liner zvishoma tekinoroji yakaitwa nekuunzwa kweiyo thermal spraying tekinoroji.Iko kushandiswa kwekupisa kwekupisa kunoitwa panguva yekugadzira injini block.Kupfapfaidza kunoiswa pamusoro pe pretreated aruminiyamu injini silinda bores.Iyo yekupfapfaidza inowedzera kusapfeka inomira yeyakaderera-carbon alloy coating kutsiva yechinyakare cast iron silinda liner.Kugadziriswa kwema cylinder blocks asina liner kunosanganisira anotevera akazara masisitimu zvikamu uye mashandisirwo:
● kukanda
● rough machining cylinder block
● texturing-roughing up the cylinder bore
● preheating pamusoro
● kupisa kwemafuta
● kupedza kugadzira
● kupedza kukudza
Maitiro akakosha ehumburumbira mashoma liner tekinoroji inoitwa pane coaxial surface (masilinda maviri ane cylindrical surfaces anosanganisira mitsetse inopfuura nepakati pemadenderedzwa mundege yakapihwa uye inotenderera kune iyi ndege) nekukwasharara kwehumburumbira.Izvi zvinoonekwa ne:
Chinangwa chekukwesha kwepamusoro chinodiwa kuti uwedzere nzvimbo yepasi kuti igadzire chimiro chepamusoro chinobvumira kuti kupfekedzwa kusungirwe nemuchina pamusoro peiyo substrate, kuwedzera mechanical bite simba rejasi kune substrate uye kuwedzera kushandura uye kusimudzira pamusoro. Material kusunga simba.Surface roughening inoitwa nenzira dzakasiyana siyana, senge grit blasting, mechanical roughing, uye high-pressure water-jet roughening.Grit blasting ndiyo inonyanya kushandiswa roughening kurapwa uye inoshanda kune ese masimbi surface roughening.
Nzvimbo dzesimbi dzinogona kucheneswa, dzoitwa rough uye dzova reactive zvakanyanya mushure mekuita jecha.Nzvimbo yakakasharara iyi inobva yacheneswa neoiri-isina high pressure yakaoma mweya usati waisa mushonga wekupfapfaidza.
Roughing (Surface Activation) inogona zvakare kuitwa nekushandisa muchina.Uye kune maitiro ekuti iyo aluminium pamusoro inoumbwa kuita imwe contour.Izvi zvinoitwa nekushandisa imwe-axis machining centre uye kushandiswa kwezvishandiso zvekucheka zvakaiswa.Iyi inguva-imwe yekugadzirisa kupedzisa maitiro mune inodhura nzira.Panyaya yehumburumbira yesimbi yakare inorovera zvakanyanya, maturusi akanyanya kupfeka uye kubvaruka akagadzirwa kazhinji zvichiita kuti izvi zvisagamuchirwe mune zvehupfumi.
High-pressure water jet roughening inongoshanda kune aluminum cylinder uye haishande necast iron cylinder.Iyo Mvura jet process haishandisi zvinodhura mabrasives.Zvisinei kushandiswa kwakananga kwejeti remvura pane substrate pamusoro kunongoitwa kana pasi pakaoma.Uye kunyange ipapo iyo yepamusoro roughness kukosha yakaderera kana ichienzaniswa nemamwe maitiro.
Surface roughening seyakakosha maitiro mune isiri-cylinder tekinoroji inobata zvakananga kusimba kwekubatanidza uye kupfekedza zvimiro zvejasi.Naizvozvo, zvakakosha kuti titarise kune iyo roughening maitiro mukushandisa silinda shoma silinda block tekinoroji.Kusarudzwa kweiyo yakakodzera roughing nzira yakakosha mukuwana yakanakisa activation yepasi uye kugona kugadzira.
