Pistoni zvindori

Zvindori zvepistoni zvine zvindori zvine gapana duku, risingazivikanwi. Inowanikwa munzvimbo dzekunze pamadziro ekunze kwepistoni mumhando dzose dzekuendesa injini (somuenzaniso, mumotokari engoro kana mukati memoto).

Sei tichida zvindori zvepistoni?

1. Kuchengetedza kamuri rinopisa. Kushandura zvindori kunowedzera kuwedzera kudzvinyirira. Nechiedza, kuputsika kana kupfeka zvindori, injini inogona kusatanga kana kurasikirwa nesimba.
2. Kuvandudza kupisa kupisa kuburikidza nemadziro eiri. Rings inobatsira kupisa kupisa kubva piston, nokudaro kudzivirira kupisa.
3. Kuderedza kushandiswa kwemafuta kwejini (mune diro-stroke diesel uye yose yechina-stroke ICE).

Mhete dzepistoni dzakagadzirirwa sei?

Iko pamwe chete (iyo imwe chete) iri pakati pemigumo ye ring ring piston. Apo piston iri muiriri, iyo lock inenge yakanyanyiswa - kusvika kune zvikamu zvishomanana zvemamiriyoni. Izvo zvinoitika oblique (nokuda kweAI-stroke ICE) uye yakananga. Zvindori zviri mu grooves zvakagadzirirwa kuitira kuti magetsi pakati pezvisungo zvienzane (2 zvindori - madigiri 180, zvindori zvitatu-120 degrees). Chigumisiro chacho chinonzi labyrinth chinoderedza kuputika kwemagesi.

Rings mafuta-anogona kubviswa uye kudzvinyirira. Mafuta ekubvisa mafuta anochengetedza kamuri rinopisa kubva mumafuta achiipinda naro kubva mucheka. Vanobvisa injini yakawandisa yemafuta kubva pairi cylinder. Isai maori -akavharidzirwa zvindori pasi pemaketani ekugadzirisa. Vane-kuburikidza. Muviri-stroke petrooline mukati memoto injini, mafuta epfumbu haashandiswi, sezvo injini inopisa pamwe chete nefurairi. Parizvino, pane zvimwe zvakakanda simbi kana zvikamu zvesimbi zvakagadzirwa nevanoshambadza. Chimiro chakareruka uye chakasvibiswa kuti chigadzire, saka ivo vanonyanya kuwanzana kupfuura kukandwa.

Kushongedza pistoni zvindori zvinodzivirira ganda rejini richibva kunoputika kwegasi kubva mumakamuri anopisa. Mune rusununguko rwemhete, rwonzi rwekunze rwukuru kudarika mukati mukati. Nokuda kwechikonzero ichi, chikamu chechigadzirwa chinobviswa. Nzvimbo yechipupuriro inonzi lock. Kazhinji, hapana mabheti akadaro akaiswa pane piston imwechete, nokuti chikonzero chekuti compaction ye piston inokwira zvishoma, uye kukanganisa kukanganiswa kunowedzera. Pa-two-stroke ICE, sekutonga, shandisa mabheti maviri. Muchinjikwa chikamu chezvinyorwa zvese zvinokonzerwa nemakona. Mucheto ane chikwata, icho chinoperera, kana chimiro chechimiro. Apo injini iri kushanda, zvindori zvakanyangarika (izvi zvinopa mukana mu groove), iyo inoita kuti iite-in.

Kugadzirwa kwezvindori zvepistoni

Teknolojia uye nzira dzekugadzira dzinofanira kupa maitiro ezvigadzirwa, izvo zvisingabhadharwi zvigaro zvingaita mazinga anodiwa ekudzvinyirira mumamiriro ayo ekushanda. Nheyo yepiston inowanzoitwa yepamusoro-simba grey cast iron, sezvo yakagadzikana yakagadzikana maitiro elastic and strength, high wear resistance, yakaisvonaka intifriction properties. Yakashandiswawo nealloying additives (kupfeka kwakanyanya kwe porous chromium, kubuda molybdenum, kuputira mujasi rema plasma, kuvhara ceramic, diamond particles), izvo zvinoita kuti kuwedzerwa kukuru kwekudzivirira kushandiswa kwemiti.
