Iro mukati meiyo cylinder liner inobatwa zvakananga nepamusoro tembiricha uye high pressure gasi, uye inogara iine high-sliding friction nepiston ring uye piston skirt.Iyo yepamusoro inosangana nemvura inotonhorera, zvichikonzera kushushikana kwakanyanya kwekushisa pasi pekusiyana kukuru kwekushisa, uye kunosvibiswa nemvura inotonhorera.Iro divi repistoni pa cylinder liner haingo wedzera kukwenya kwemukati, asiwo kunoita kuti ikotame.Iyo piston zvakare inorova humburumbira liner kana iyo yedivi inorovera yachinja nzira.Mukuwedzera, iri pasi pekuiswa kukuru kwekutanga.
Iyo gasi dzvinyiriro inoburitsa tangential tensile kushushikana uye radial compressive kusagadzikana pamadziro ecylinder, uye ndiyo hombe pane yemukati nzvimbo, ese ari akakwira-frequency pulsating stress.
Nekuda kwekushushikana kukuru kwekupisa kunokonzerwa nemusiyano wekushisa pakati pemukati nekunze kwe cylinder wall, compressive stress inoitika mukati memukati uye tensile stress iripo panzvimbo inotonhorera pasi petembiricha yakajairika.Nekudaro, pasi pekupisa kwakanyanya, simbi iri padhuze nemukati memukati inoenda kunokambaira epurasitiki deformation, uye mushure mekutonhora, yakasara tensile kusagadzikana inoumbwa pamusoro pemukati.Izvi zvakaderera-frequency kusagadzikana kunokonzerwa nekutanga uye kumisa shanduko kunokonzeresa kuneta kwezvinhu.
Iyo cylinder liner inofanira kuva nesimba rakakwana, rigidity uye kupisa kupisa, pamwe chete nekunaka kupfeka kusagadzikana.Panofanira kuva nekuzora kwakanaka uye kutonhora panguva yebasa.
Humburumbira liner inowanzo gadzirwa ne-wear-resistant alloy cast iron ine phosphorus kana boron, yakadai seHT25-47, HP-CuCrMo, etc. Iro mukati meiyo cylinder liner dzimwe nguva inobatwa ne chrome plating (chrome plating pamakomba asina kusimba, chrome plating pamafuta ekuchengetera mafuta), nitriding kana phosphating yekuvandudza kupfeka kuramba.Kuomarara kwemukati kwecylinder liner kunowanzo kudiwa kuti ive yakakura kupfuura HB200, uye ine kuenzanisa kwakanaka nekuoma kwepiston mhete.Iyo yemukati yemukati inofanirwawo kunge iine hukasha hwakakodzera, kuitira kuti ive neimwe mafuta ekuchengetedza huwandu uye inomhanya-mukuita.Nzvimbo yemukati inofanira kuva nekutenderera kwakakwana uye cylindricity accuracy, uye chitsigiro chinosungirirwa chakatarisana nechepakati pegomba remukati chinofanira kuva nepamusoro pemamiriro ekugadzirisa.
