Chii chinonzi Piston Rings?
Tsanangudzo uye Magadzirirwo
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
Piston mhete dzinoita matatu akakosha mabasa:
1.Kuisa chisimbiso mukamuri yekupisa:Dzivirira kubuda kwegasi panguva yekupisa, kuve nechokwadi chekubuda kwemagetsi akawanda.
2. Heat transfer:Kufambisa kupisa kubva papiston kuenda kumadziro ecylinder, kudzivirira kupisa.
3.Oil control:Rongedza kugoverwa kweoiri pamadziro ecylinder kuderedza kukweshera uku uchidzivirira mafuta akawandisa kupinda mukamuri rinopisa.
Sei Pistons Iine Mhete Matatu?
Basa reRing imwe neimwe
Injini zhinji dzinoshandisa zvindori zvitatu zvepiston, imwe neimwe yakagadziridzwa kune rimwe basa:
1.Top Compression Ring:
- Inoshingirira kudzvanywa kwepamusoro uye tembiricha.
- Inovhara magasi ekupisa kuti awedzere kushanda kweinjini.
2.Second Compression Ring:
- Inotsigira mhete yepamusoro mukuvhara magasi.
- Inobatsira mukupisa kupisa.
3.Oil Control Ring (Scraper Ring):
- Inobvisa mafuta akawandisa kubva pamadziro ecylinder.
- Inodzosera mafuta ku crankcase, kuderedza kushandiswa uye kubuda.
Nei Zvisina Zvishoma Kana Kupfuura?
- Mhete shoma: Njodzi yekusavharwa zvakanaka, kuwedzera kushandiswa kwemafuta, uye kuderedzwa kweinjini.
- Mamwe mhete: Kukweshana kwepamusoro, kuderedzwa kwemagetsi, uye kuoma kusingakoshi. Iyo mitatu-mhete dhizaini inoyera kuita, kusimba, uye mutengo-kubudirira.
Chii Chinoitika Kana Piston Mhete Dzakakundikana?
Kazhinji 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.
Migumisiro Yenguva Yakareba
Kuregeredza zvindori zvepiston zvakasakara zvinogona kutungamirira kune:
- Permanent humburumbira rusvingo kukuvara.
- Catalytic converter kutadza nekuda kwekusvibiswa kwemafuta.
- Injini inodhura kugadzirisa kana kutsiva.
Ndinoziva Sei Kana Piston Rings Yangu Inoda Kutsiviwa?
Diagnostic Nzira
1.Compression Test: Inoyera kudzvanywa mukamuri yekupisa. Low compression inoratidza kupfeka mhete.
2.Leak-Down Test: Inozivisa kunobva kudzvinyirira kurasikirwa (semuenzaniso, mhete vs. mavharuvhu).
3.Oil Consumption Analysis: Kurasikirwa kukuru kwemafuta pakati pekuchinja kunoratidza kukanganisa mhete.
4.Visual Inspection: Utsi hwebhuruu kana mafuta akasara mune exhaust system.
Nguva Yokuita
- Tsiva zvindori kana compression inodonha pazasi magadzirirwo emugadziri.
- Gadzirisa zviratidzo nekukurumidza kudzivirira kuparara kweinjini.
Niche Zvishandiso mune Zvakanyanya Nzvimbo
