Imwe ruzivo nezve pistons

Piston ndeyekudzokorodza kufamba muhumburumbira muviri weinjini yemotokari. Iyo yakakosha chimiro chepiston inogona kukamurwa kuva pamusoro, musoro uye siketi. Pamusoro pepiston ndiyo chikamu chikuru chekamuri yekupisa, uye chimiro chayo chine hukama neiyo yakasarudzwa yekamuri yekupisa fomu. Injini dzepeturu dzinowanzo shandisa flat top piston, iyo ine mukana wenzvimbo diki yekupisa kupisa. Diesel engine piston top inowanzova nemakomba akasiyana siyana, chimiro chayo, chinzvimbo uye saizi inofanirwa kunge iine injini yedhiziri musanganiswa wekugadzira uye kupisa zvinodiwa.

Nekuti iyo yemukati yekupisa injini piston inoshanda pasi pekushisa kwepamusoro, kudzvanywa kwakanyanya uye mamiriro emutoro wakakwira, zvinodikanwa zvepiston zvakakwira, saka kupatsanurwa kweinjini yekupisa yemukati kunonyanya kukurukurwa.
1. Maererano nemafuta anoshandiswa, anogona kugoverwa kuva peturu injini piston, dizeli injini piston, gasi piston.
2. Maererano nezvinhu zvepiston, inogona kukamurwa kuita piston yesimbi yakakandwa, piston yesimbi, aluminium alloy piston uye piston yakasanganiswa.
3. Zvinoenderana nemaitiro ekugadzira piston blanks, inogona kupatsanurwa kuita gravity casting piston, extrusion casting piston uye forged piston.
4. Maererano nemamiriro ekushanda kwepiston, inogona kugoverwa mumapoka maviri: piston isina-pressurized uye piston yakamanikidzwa.
5. Zvinoenderana nechinangwa chepiston, inogona kukamurwa kuita piston yemota, rori piston, mudhudhudhu piston, Marine piston, tank piston, tirakita piston, lawn mower piston, nezvimwe.

Iine simba reinjini yemotokari, hupfumi, kuchengetedza kwezvakatipoteredza uye kuvimbika zvinodiwa zvakanyanya uye zvakanyanya kuomarara, piston yakagadzirika kuita yepamusoro-tekinoroji chigadzirwa chinobatanidza huremu uye yakakwirira-simba zvinhu zvitsva, yakakosha-yakaumbwa cylindrical composite nzvimbo, akasarudzika-akaumbwa mapini maburi. uye mamwe matekinoroji matsva ekuona kupisa kwekudzivirira, kupfeka kuramba, kutungamira kwakatsetseka uye yakanaka yekuisa chisimbiso basa repiston. Deredza kukwesha basa kurasikirwa kweinjini, kuderedza kushandiswa kwemafuta, ruzha uye kuburitsa. Kuti usangane nezvinodiwa pamusoro pekushanda, denderedzwa rekunze repiston rinowanzogadzirwa seyakakosha chimiro chekunze denderedzwa (convex variable ellipse), kureva, chikamu chemuchinjikwa perpendicular kune axis yepiston iellipse kana kugadziriswa ellipse, uye ellipticity inoshanduka pamwe chete neaxis maererano nemumwe mutemo (sezvakaratidzwa muMufananidzo 1), uye kururamisa kweiyo ellipticity ndeye 0.005mm; Iyo yekunze contour yeiyo longitudinal chikamu chepiston inokodzera curve yemhando yepamusoro basa, uye iko contour kurongeka ndeye 0.005 ~ 0.01mm. Kuti uvandudze kutakura kwepiston uye kuwedzera simba reinjini, maburi epini episton yakakwira anowanzo kugadzirwa kuita micro yemukati cone mhando kana yakajairika stress curved type (special pini makomba), saizi chaiyo. yemakomba epini ndeye IT4 nhanho, uye iko contour iko 0.003mm. Seyakajairwa zvikamu zvakakosha zvemotokari, piston ine yakasimba tekinoroji maitiro mukucheka. Indasitiri yekugadzira piston yemumba inowanzo umbwa neyakajairwa muchina maturusi uye yakakosha michina yakasanganiswa nehunhu hwepiston process machining line, saka, yakakosha michina yave yakakosha midziyo yepiston yekucheka kugadzira, uye basa rayo nekurongeka kwayo kuchakanganisa zviratidzo zvehutano zvezvinhu zvakakosha zvechigadzirwa chekupedzisira.
