Piston Rings
Key Takeaways
Piston Rings: Zvinhu zvakakosha zvinosimbisa makamuri ekupisa, zvinogadzirisa oiri, uye kutamisa kupisa.
Zvindori zvitatu: Mhete imwe neimwe inoita basa rakasiyana-kusunga chisimbiso, kutengesa kupisa, uye kutonga kwemafuta.
Kukundikana Zviratidzo: Kurasikirwa kwesimba, kunyanya kushandisa mafuta, utsi hwebhuruu, kana kukanganisa.
Professional Solutions: Yepamusoro-mhando zvinhu uye chaiyo engineering inovimbisa kusimba uye kuita mumamiriro akanyanya.
Chii chinonzi Piston Rings?
Piston mhete denderedzwa esimbi mabhendi akaiswa akatenderedza pistons mukati meinjini dzinopisa. Iwo akapatsanurwa kubvumira kuwedzera uye kuputika panguva yekushanda. Inowanzo gadzirwa nesimbi yakakandwa, simbi, kana alloys epamberi, mhete dzemazuva ano dzepiston dzakagadzirwa kuti dzimire kutonhora kwakanyanya, kudzvanywa, uye kupokana.
Primary Mabasa
Kuisa Chisimbiso Iyo Combustion Chamber: Dzivirira kubuda kwegasi panguva yekupisa, kuve nechokwadi chekubuda kwemagetsi.
Heat Transfer: Itai kupisa kubva papiston kuenda kumadziro ecylinder, kudzivirira kupisa.
Oiri Kudzora: Rongedza kugoverwa kweoiri pamadziro ecylinder kuti uderedze kukweshera uku uchidzivirira mafuta akawandisa kupinda mukamuri yekupisa.
Sei Pistons Iine Mhete Matatu?
Injini zhinji dzinoshandisa zvindori zvitatu zvepiston, imwe neimwe yakagadziridzwa kune rimwe basa:
Yepamusoro Compression Ring: Inomira yakanyanya kudzvanywa uye tembiricha, kuvhara gasi rinopisa kuti riwedzere kushanda kweinjini.
Yechipiri Compression Ring: Inotsigira mhete yepamusoro mukuvhara magasi uye inobatsira mukupisa kupisa.
Oil Control Ring (Scraper Ring): Inokwenya mafuta akawandisa kubva pamadziro ecylinder uye inodzosera mafuta ku crankcase, kuderedza kushandiswa uye kubuda.
Chii Chinoitika Kana Piston Mhete Dzakakundikana?
Zvakajairika Zviratidzo zvekukundikana:
Kurasikirwa kwesimba reinjini: Kudonhedza kudzvanya kunoderedza kupisa kwemoto.
Kunyanya kushandiswa kwemafuta: Mhete dzakasakara dzinobvumira mafuta kupinda mukamuri rinopisa.
Utsi hweblue exhaust: Oiri inopisa inoburitsa tint yebluish mumagasi emhepo.
Kuwedzera kwehutsi: Mhete dzakakundikana dzinobatsira pakukwira kwehydrocarbon.
Injini inodzima moto: Kusaenzana kudzvinyirira kunokanganisa kutenderera kwekupisa.
Yenguva Yakareba Mhedzisiro: Kuregeredza mhete dzepiston dzakasakara zvinogona kutungamira kukuvadzwa kwecylinder madziro, kutadza kuchinjisa shanduko nekuda kwekusvibiswa kwemafuta, uye kudhura kweinjini kana kutsiva.
