Chii chinonzi kurongedza bhandi remhete yepiston yemotokari
Kurongedza bhandi remupendero wepiston yemotokari kunowanzoreva kuisa rin'i yepiston mumudziyo wekurongedza chaiwo kuti idzivirire kubva mukukuvadzwa uye kuita kuti kutakurwa nekuchengetwa zvive nyore. Nzira dzakajairika dzekurongedza dzinosanganisira kurongedza mabhegi epurasitiki, kurongedza makatoni uye kurongedza mabhokisi esimbi.
Nzira dzakajairika dzekurongedza uye hunhu hwadzo
Kurongedza mabhegi epurasitiki: Rudzi urwu rwekurongedza rwakareruka, runotora nzvimbo diki, runogona kudzivirira ngura yepiston ring. Zvisinei, piston ring yebhegi repurasitiki kazhinji haina kunaka, uye vamwe vagadziri vanofukidza kunze nebhokisi repepa kana kraft paper.
Kurongedza kwekatoni: chitarisiko chekatoni chakanaka, chiri nyore kubata, chinogona kuiswa mamaki ari nyore. Vasati varongedza, vamwe vagadziri vanopfapfaidzawo anti-oxidation coating pamusoro peringi yepiston kuti iwedzere hupenyu hwayo hwekushanda. Kurongedza kwekatoni kunogonawo kuva kurongedza kwechipiri kweringi yepiston kudzivirira kukweshana.
Kurongedza bhokisi resimbi: Kugadzira tinplate kunowanzo shandiswa, mhando iyi yekurongedza yepamusoro-soro uye inodzivirira hunyoro, inogona kuparadzanisa hunyoro zvinobudirira, kuchengetedza mhete yepiston.
Ruzivo rwekutanga nezve mhete dzepiston
Mhete yepiston yakaiswa mumugero wepiston mukati memhete yesimbi, yakakamurwa kuita mhete yekumanikidza uye mhete yemafuta maviri. Mhete yekumanikidza inoshandiswa kuvhara musanganiswa unobvira mukamuri rinopisa, nepo mhete yemafuta inoshandiswa kukwenya mafuta akawandisa kubva musirindiri. Mhete yepiston imhando yemhete yesimbi inonamira ine deformation yakakura yekunze, iyo inoenderana nemusiyano wekumanikidza kwegasi kana mvura kuti igadzire chisimbiso pakati pedenderedzwa rekunze remhete nesirinda, uye pakati pemhete nemurindi wemhete .
Matanho ekudzivirira kuiswa kwemhete yepiston yemotokari anosanganisira zvinhu zvinotevera:
Iva nechokwadi chekuti mhete yepiston yakaiswa zvakanaka mu cylinder liner, uye chengeta nzvimbo yakakodzera yekuvhura panzvimbo inopindirana, iyo inokurudzirwa kudzorwa iri pakati pe 0.06-0.10mm . Izvi zvinogona kuve nechokwadi chekuti mhete yepiston haizokonzere kukweshana kwakanyanya uye kusakara nekuda kwenzvimbo diki.
Mhete yepiston inofanira kuiswa zvakanaka papiston, uye kuve nechokwadi chekuti pane nzvimbo yakakodzera yerutivi pamwero we ring groove, inokurudzirwa kuchengetedza pakati pe 0.10-0.15mm . Izvi zvinogona kuve nechokwadi chekuti mhete yepiston haizovharike nekuda kwemukana mudiki kana kubuda kwemukana mukuru.
Mhete yechrome inofanira kuiswa panzvimbo yekutanga, uye gomba harifanirwe kunge rakanangana negomba remagetsi riri pamusoro pepiston. Izvi zvinoderedza kusakara nebasa.
Maburi emhete dzepiston anofanira kunge akatenderedzwa nemadhigirii zana nemakumi maviri kubva kune mumwe nemumwe uye haafanirwe kuenderana nemaburi emapiston. Izvi zvinodzivirira kudedera uye kupera kwemhete yepiston panguva yekushanda.
Pakuisa rin'i yepiston yechikamu chekoni, chiso chekoni chinofanira kutarisa mudenga . Pakuisa rin'i yetorsion, chamfer kana groove zvinofanirawo kutarisa mudenga. Pakuisa rin'i yekubatanidza, isa rin'i ye axial lining kutanga, yoteverwa nerin'i yakatsetseka nerin'i yakakombama, uye maburi emhete yega yega anofanira kunge akatenderedzwa .
Paunenge uchiisa, chengetedza nzvimbo inogumira pakati peringi yepiston neringi yesilinda yakachena kudzivirira kukanganiswa kubva mukusviba netsvina. Mushure mekuisa, tarisa kana nzvimbo inogumira pakati peringi yepiston neringi yesilinda yakaenzana kudzivirira kusundidzira zvakanyanya kana kuti kusimba zvakanyanya.
Shandisa maturusi akakosha kuisa , akadai sema "special assembly pliers" ema "piston rings", "cone sleeves", nezvimwewo. Izvi zvinoderedza njodzi yekuti "piston ring" ikuvadzwe kana kukanganiswa ne "overexpansion".
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemotokari zveMG&750 zvinogamuchirwa Kutenga.
