Kune mhando mbiri dzepiston mhete dzekugadzirisa injini:saizi yakajairika uye saizi yakawedzera. Isu tinofanirwa kusarudza mhete yepiston zvinoenderana neyakapfuura silinda yekugadzirisa saizi. Kana mhete yepiston yehukuru husina kunaka yakasarudzwa, inogona kunge isingakodzeri, kana kusiyana pakati pezvikamu zvakakura zvikuru. Asi mazuvano mazhinji acho akaenzana, mashoma awo akakurisa.

Kuongororwa kwe elasticity yepiston mhete:Iyo elasticity yepiston mhete ndeimwe yeakakosha mamiriro ekuona kusimba kwecylinder. Kana iyo elasticity yakakura kwazvo kana idiki, haina kunaka. Inofanira kusangana nezvinodiwa zvehunyanzvi. Iyo piston mhete elasticity tester inowanzo shandiswa pakuona. Mukuita, isu tinowanzo shandisa ruoko kutonga zvine hukasha, chero bedzi isina kunyanya kusununguka, inogona kushandiswa.

Kuongororwa kwekudonha kwechiedza chepiston mhete uye cylinder madziro:Kuti uve nechokwadi chekuisa chisimbiso chemhete yepiston, nzvimbo yekunze yemhete yepiston inofanirwa kuve yakabatana nemadziro ecylinder kwese. Kana kubuda kwemwenje kwakakurisa, nzvimbo yekusangana yenzvimbo yepiston mhete idiki, izvo zvinogona kutungamira kune yakawandisa kuvhuvhuta-negasi uye yakawandisa mafuta kushandiswa. Pane midziyo yakakosha yekuona kubuda kwechiedza chepiston mhete. Izvo zvinodikanwa ndezvekuti: hapana kubuda kwechiedza kunobvumidzwa mukati me30 ° yekuvhurika kwekupedzisira kwepiston mhete, uye hapana anopfuura maviri mavhenekera emwenje anobvumidzwa pane imwechete piston mhete. Iyo inoenderana yepakati kona haifanire kudarika 25 °, iyo yakazara yepakati kona inoenderana nemwenje inodonha arc kureba pane imwechete piston mhete haifanire kudarika 45 °, uye gaka pakubuda kwechiedza harifanire kudarika 0.03mm. Kana izvo zviri pamusoro zvisingasviki, unofanirwa kusarudza zvakare mhete yepiston kana kugadzirisa humburumbira.

Zvakakosha kuziva kuti mhete yepiston isati yaiswa, zvakakosha kuona kana cylinder liner iriwo chrome-plated.Kana pamusoro pepiston ring uye cylinder liner zvave chrome-plated, zviri nyore kubudisa chiitiko. yeCylinder zvibodzwa.
