Piston mhete.
Piston Ring (Piston Ring) inoshandiswa kunyudza piston groove mukati memhete yesimbi, piston mhete yakakamurwa kuita marudzi maviri: mhete yekumanikidza uye mhete yemafuta. Mhete yekumanikidza inogona kushandiswa kuvhara gasi rinopisa rinopisa mukamuri rinopisa; Iyo mhete yemafuta inoshandiswa kukwenya mafuta akawandisa kubva muhumburumbira. Iyo piston mhete imhando yesimbi elastic mhete ine yakakura yekuwedzera deformation, iyo inounganidzwa muprofile uye inoenderana annular groove. Mhete dzepiston dzinodzorera uye dzinotenderera dzinotsamira pamusiyano wekumanikidzwa kwegasi kana mvura kuti igadzire chisimbiso pakati pedenderedzwa rekunze remhete necylinder uye rimwe divi remhete nemhete groove.
Piston mhete basa rinosanganisira kuvhara, kudzora mafuta (kudzora mafuta), kupisa conduction (kupisa kupisa), kutungamira (rutsigiro) mabasa mana. Kuisa chisimbiso: kunoreva kuisa chisimbiso gasi, usarega kamuri yekupisa gasi ichidonha kune crankcase, iyo gasi kuvuza kunodzorwa zvishoma, kunatsiridza kupisa kwekupisa. Kubuda kwemhepo hakuzongodzikisi simba rejini, asiwo kuita kuti mafuta awedzere, iro ndiro basa guru remhete yegesi; Gadzirisa mafuta (oiri kutonga): iyo yakawandisa mafuta ekuzora pamadziro ecylinder inobviswa, uye cylinder madziro akafukidzwa nemafuta akaonda firimu kuti ave nechokwadi chekuzora kwakajairika kwecylinder uye piston uye mhete, rinova iro basa guru re mhete yemafuta. Mune injini dzemazuva ano dzepamusoro-soro, kunyanya kukoshesa kunobhadharwa kune basa repiston ring control oil film; Heat conduction: kupisa kwepiston kunoendeswa kune cylinder liner kuburikidza nemhete yepiston, kureva, iyo inotonhorera. Zvinoenderana nedatha yakavimbika, 70 ~ 80% yekupisa yakagamuchirwa nepiston kumusoro kwepiston isina kunyungudutswa inoparadzirwa kuburikidza nepiston mhete kumadziro ecylinder, uye 30 ~ 40% yepiston inotonhorera inoparadzirwa kuburikidza nepiston mhete kune cylinder. wall; Tsigiro: Mhete yepiston inochengeta piston mucylinder, inodzivirira kusangana kwakananga pakati pepiston uye cylinder madziro, inova nechokwadi chekufamba kwakanaka kwepiston, inoderedza kupokana, uye inodzivirira piston kugogodza silinda. Kazhinji, piston yeinjini yepeturu inoshandisa mhete mbiri dzegasi uye mhete imwe yemafuta, nepo injini yedhiziri inowanzoshandisa zvindori zviviri zvemafuta uye mhete imwe yegasi.
Iyo chaiyo yekuisa nzira yepiston mhete ndeiyi inotevera:
1. Kutanga kudiwa kuisa mhete yemafuta, ipapo mhete yegesi, urongwa huri pasi-kumusoro;
2. Kana mhete imwe neimwe yaiswa, kuvhurwa kwepiston mhete haifaniri kuwedzerwa zvakanyanya, zvakakwana kuti ipinde mupiston;
3. Isai mhete yemafuta yakasanganiswa:
Isai mhete ye liner mupiston yemafuta ring groove, teererai pakuvhurwa kwerin'i mhete haigone kupindirana; Isa mahwendefa esimbi epasi nepamusoro pasina kushandisa midziyo yekuvhura maburi. Pakuisa, tanga wasungirira imwe mugumo wesimbi yepasi mundiro yeringi, dzvanya simbi yekuvhura nzvimbo nechigunwe chako, tsvedza chigunwe cherumwe ruoko muchikamu chemhete parutivi rwesimbi, wobva waisa ndiro yepamusoro yesimbi nenzira imwecheteyo. Usaisa mahwendefa epamusoro uye epasi pasi kune rumwe rutivi rwemhete yerineni; Kuti udzivise kupindirana kwemaringi ekuvhurwa kwe liner kana piston ikasundirwa mucylinder, zunza maburi ekumusoro neazasi nemajoini erin'i ne90 kusvika 120 madhigirii. Mushure mekuisa, tenderera zvinyoro nyoro mhete yemafuta yakasanganiswa nemaoko, uye inofanira kunge yakatsetseka isina kunamatira.
4. Gasi mhete yekuisa:
Shandisa maturusi akakosha kuisa mhete mbiri dzegasi uye mhete imwe yegasi, usadzorere mhete yekutanga yegasi uye yechipiri mhete yegesi; Kana yaiswa, rutivi rwacho rwakanyorwa (HYR, HY, CSR, TLK, ALS, H, R, nezvimwewo). Inofanira kutarisana kumusoro (piston head direction); Kuzunungusa kuvhurwa kwemhete yegesi 180 madhigirii, usatendeuke kuvhura kwakanangana nepini yepiston.
5. Usati waunganidza mhete yepiston mu cylinder, zvakakosha kugadzirisa nzvimbo yekuvhura yepiston mhete imwe neimwe.
Piston mhete basa:
1. Kuisa chisimbiso
Iyo piston mhete inogona kuchengetedza chisimbiso pakati pepiston uye cylinder madziro, uye iyo inodonha inodzorwa zvishoma, iyo inotakurwa nemhete yegesi. Inogona kudzivirira silinda nepiston kana silinda nepiston mhete nekuda kwekubuda kwemhepo pakati pekuruma; Inogonawo kudzivirira kutadza kunokonzerwa nemafuta ekuzora.
Danho 2 Itai kupisa
Iyo piston mhete inogona kutamisa uye kuparadzira kupisa kwakanyanya kunogadzirwa nekupisa kumadziro ecylinder, uye inogona kuita basa mukutonhodza piston.
3. Oil control function
Iyo piston mhete inogona kukwenya mafuta ekuzora akasungirirwa kumadziro ecylinder kuchengetedza kushandiswa kwemafuta kwakajairwa, ayo anotakurwa nemhete yemafuta.
4. Kutsigira maitiro
Mhete yepiston inofamba ichikwira nekudzika mucylinder, uye nzvimbo yayo inotsvedza inotakurwa zvachose nemhete yepiston, ichidzivirira pisitoni kuti isabate humburumbira zvakananga uye kutamba basa rinotsigira.
Kune marudzi maviri ezvindori zvepiston: zvindori zvegesi uye zvindori zvemafuta. Mhete yegesi inoshandiswa kuve nechokwadi chekusimbisa pakati pepiston necylinder uye kuvhara mweya wakamanikidzwa mukamuri yekupisa. Iyo mhete yemafuta inoshandiswa kukwenya mafuta akawandisa pacylinder, izvo zvinogona kudzivirira mafuta kuti asapukunyuke mucylinder nekupisa.
