1. Ichange iine simba rakakwana, kuomarara, huremu hudiki, uye huremu huremu kuti ive nechokwadi chesimba risingaite.
2. Good thermal conductivity, high temperature resistance, high pressure, corrosion resistance, kukwana kupisa kwekupisa simba, uye nzvimbo diki yekupisa.
3. Panofanira kuva nekadiki kadiki yekukakavadzana pakati pepiston nemadziro episton.
4. Kana kutonhora kuchichinja, ukuru uye kuchinja kwechimiro kunofanira kunge kuri kuduku, uye kusununguka kuduku pakati pe cylinder wall uye cylinder inofanira kuchengetedzwa.
5. Yakaderera coefficient yekuwedzera kwekupisa, diki chaiyo giravhiti, yakanaka yekupfeka kuderedza uye simba rekupisa.
Basa repiston
Nekuwedzera kusimba kwezvinodiwa zvesimba, hupfumi, kuchengetedza kwezvakatipoteredza, uye kuvimbika kweinjini mumotokari yese, piston yakagadzira chigadzirwa chepamusoro-soro chinobatanidza matekinoroji mazhinji akadai seakareruka uye akasimba-akasimba zvinhu zvitsva, zvakakosha. -shaped cylindrical composite surfaces, uye maburi epini akasarudzika, kuve nechokwadi chekudzivirira kupisa, kupfeka kuramba, kutungamira kwakagadzikana, uye basa rekuisa chisimbiso chepiston, kuderedza kukweshera kwekushanda kweinjini, uye kuderedza kushandiswa kwemafuta Noise uye kubuda.
Kuti usangane nezvinodiwa pamusoro pekushanda, denderedzwa rekunze repiston rinowanzogadzirwa seyakasarudzika-yakaita denderedzwa rekunze (convex to elliptical), kureva kuti, chikamu chemuchinjikwa perpendicular kune piston axis is ellipse kana ellipse yakagadziridzwa, uye ovality inoshanduka ichitevedza axis kutungamira maererano neimwe mutemo (sezvakaratidzwa muFigure 1), ine ovality yechokwadi ye0.005mm;Iyo yekunze contour yepiston longitudinal chikamu inokodzera curve yehupamhi hwepamusoro basa, ine contour accuracy ye 0.005 kusvika 0.01 mm;Kuti uvandudze kutakura kwepiston uye kuwedzera simba reinjini, gomba repini repiston yakakwira rinowanzo gadzirwa senge diki yemukati cone mhando kana yakajairika stress curved pamusoro pemhando (yakasarudzika-yakaita pini gomba), ine pini hole saizi yechokwadi yeIT4 uye iko contour kurongeka kwe0.003mm.
Piston, seyakajairwa kiyi yemotokari chikamu, ine yakasimba tekinoroji maitiro mukugadzira.Muindasitiri yekugadzira piston yemumba, mitsara yekugadzira machining inowanzo umbwa neyakajairwa-chinangwa muchina maturusi uye yakasarudzika michina inosanganisa hunhu hwepiston tekinoroji.
Naizvozvo, midziyo yakakosha yave yakakosha midziyo yepiston machining, uye basa rayo uye nekurongeka kuchakanganisa zvakananga zviratidzo zvemhando yemhando yakakosha yechigadzirwa chekupedzisira.
