Pistoni.
Piston kufamba kunodzokororwa mumuviri we cylinder yeinjini yemotokari. Chimiro chikuru chepiston chinogona kukamurwa kuita pamusoro, musoro uye siketi. Pamusoro pepiston ndicho chikamu chikuru chekamuri yekubatidza, uye chimiro chayo chakabatana nechimiro chekamuri yekubatidza yakasarudzwa. Injini dzepeturu dzinonyanya kushandisa piston yepamusoro yakatsetseka, iyo ine mukana wenzvimbo diki yekupinza kupisa. Piston yeinjini yedhiziri inowanzova nemakomba akasiyana-siyana, chimiro chayo chaicho, nzvimbo uye saizi inofanira kunge inoenderana nekuumbwa kwemusanganiswa weinjini yedhiziri uye zvinodiwa zvekubatidza.
Pamusoro pepiston chikamu chekamuri rinopisa, saka rinowanzogadzirwa nemaumbirwo akasiyana, uye piston yeinjini yepeturu inonyanya kushandisa pamusoro wakatsetseka kana pamusoro wakakombama, kuitira kuti imba inopisa ive diki, nzvimbo yekudzima kupisa ive diki, uye maitiro ekugadzira ari nyore. Mapiston emusoro weConvex anowanzo shandiswa mumainjini maviri epeturu. Pamusoro pepiston yeinjini yedhiziri anowanzo gadzirwa nemakomba akasiyana-siyana.
Musoro wepiston ndiwo chikamu chiri pamusoro pechigaro chepiston pin, uye musoro wepiston wakaiswa neringi yepiston kudzivirira kupisa kwakanyanya uye gasi rinomanikidzwa zvakanyanya kuti risapinde mucrankcase uye kudzivirira mafuta kuti asapinde mukamuri rinopisa; Kupisa kwakawanda kunotorwa nepamusoro pepiston kunoendeswawo kucylinder kuburikidza nemusoro wepiston, uye wobva waendeswa kuburikidza nepakati pekutonhodza.
Musoro wepiston unogadziriswa ne ring grooves dzakawanda dzekuisa piston rings, uye huwandu hwepiston rings hunoenderana nezvinodiwa nechisimbiso, izvo zvine chekuita nekumhanya kweinjini uye kumanikidzwa kwe cylinder. Injini dzinomhanya zvakanyanya dzine rings shoma pane injini dzinomhanya zvishoma, uye injini dzepeturu dzine rings shoma pane injini dzedhiziri. Injini dzepeturu dzinoshandisa rings mbiri dzegasi ne ring imwe yeoiri; Injini yedhiziri ine rings nhatu dzegasi ne ring imwe yeoiri; Injini yedhiziri inomhanya zvishoma inoshandisa rings nhatu kusvika ina dzegasi. Kuti kuderedza kurasikirwa kwekukweshana, kukwirira kwechikamu chebhandi kunofanira kuderedzwa zvakanyanya sezvinobvira, uye huwandu hwerings hunofanira kuderedzwa kana paine chokwadi chekuti zvinovharwa.
Zvikamu zvese zvemhete yepiston zviri pasi pemugero zvinonzi masiketi episton. Basa rayo nderekutungamira piston iri musirindiri kuti ifambise pamwe chete uye igare yakamanikidzwa. Kana injini ichishanda, nekuda kwesimba remhepo iri musirindiri, piston inokotama uye inochinja chimiro. Kana piston yapiswa, huwandu hwekuwedzera hunopfuura hwedzimwe nzvimbo nekuda kwesimbi iri papiston pin. Pamusoro pezvo, piston inogadzira extrusion deformation pasi pesimba rekumanikidzwa kwedivi. Nekuda kwekushanduka kwataurwa pamusoro apa, chikamu chepiston skirt chinova ellipse munzira ye long axis yakatarisana nepiston pin. Pamusoro pezvo, nekuda kwekupararira kusina kuenzana kwekushisa nehuremu pamwe chete ne axis yepiston, kuwedzera kwekupisa kwechikamu chimwe nechimwe kwakakura pamusoro uye kudiki pasi.
Kukundikana kukuru kwemusangano wepiston uye zvikonzero zvavo ndeizvi:
1. Kubviswa kwenzvimbo yepamusoro yepiston. Kubviswa kwepiston kunoonekwa pamusoro pepiston, paine maburi akasununguka muzvikamu zvakapfava uye kunyunguduka kwenzvimbo muzvikamu zvinorema. Chikonzero chikuru chekubviswa kwenzvimbo yepamusoro yepiston kunokonzerwa nekutsva kusingawanzoitiki, zvekuti pamusoro payo panogamuchira kupisa kwakawandisa kana kumhanya pasi pemutoro mukuru mushure mekunge rin'i yepiston yanamira uye yatyoka.
2, pamusoro pepiston pakatsemuka. Kwakanangana nekutsemuka pamusoro pepiston kunowanzo tarisa divi reburi repini repiston, iro rinonyanya kukonzerwa nekutsemuka kwekuneta kunokonzerwa nekumanikidzwa kwekupisa. Chikonzero: kushanda zvakanyanya kweinjini kunotungamira mukushanduka kwakanyanya kwepiston, zvichikonzera kuneta kwekutsemuka kwepamusoro pepiston;
3, kupwanyika kwemadziro emugero wepiston. Kana piston ichifamba ichikwira nekudzika, mhete yepiston inofanira kunge yakatsetseka ne radial telescopic nekukanganisika kwe silinda, kunyanya tembiricha yemugero wekutanga we ring yakakwira, uye inokanganiswa ne "kukanganiswa" kwegasi nemafuta, saka kukweshana kwe ring nekuzununguka kunoitika mu ring groove, zvichikonzera kupera simba;
4. Mhete yepiston yakanamatira mugomba reringi. Kupisa kwepiston ring kunokonzerwa nekuiswa kwemafuta anozorwa kana kurasikirwa nerusununguko rwekufamba mutangi, kutadza uku kunokuvadza zvikuru. Zvikonzero zvikuru: kupisa injini yedhiziri kana kushanda kwenguva refu, zvekuti gum yemafuta anozorwa, piston ring, cylinder deformation yakakura yekupisa; Kusvibiswa kwemafuta anozorwa kwakanyanya, mhando yemafuta anozorwa haina kunaka; Mudziyo wekufema wecrankcase unoshanda zvisina kunaka, zvichikonzera kumanikidzwa kwakanyanya kana kusasimba kwemhepo yecylinder, zvichikonzera kumhanya kwemafuta. Saka, zvakakosha kuve nechokwadi chekushandiswa kwemafuta akakodzera kudzivirira injini yedhiziri kuti isazorwa.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
