O-ring (O-rings)irabha yekuisa chisimbiso mhete ine denderedzwa muchinjikwa chikamu.Nekuda kwechikamu chayo chemuchinjikwa chakaita O, inonzi O-ring, inonziwo O-ring.Yakatanga kuoneka pakati pezana ramakore rechi 19, payaishandiswa sechisimbiso chesimbi dzesimbi.
O-mheteanonyanya kushandiswa pakuisa chisimbiso uye kudzoreredza kufambisa chisimbiso.Kana ichishandiswa pakuisa chisimbiso che rotary, inongogumira kune yakaderera-inomhanya inotenderera yekuisa chisimbiso michina.Iyo O-mhete inowanzoiswa mugomba rine rectangular cross-section pane yekunze denderedzwa kana yemukati denderedzwa kuita basa rekusimbisa.Zvisimbiso zveO-ring zvichiri kuita basa rakanaka mukuvhara uye kunyura kwekuvhunduka munzvimbo dzakaita semafuta kuramba, asidhi uye alkali, abrasion, uye kukukurwa kwemakemikari.
O-ring zvinhu:O-mhete ine yakanakisa yekuisa chisimbiso kuita uye hupenyu hurefu hwekushanda.Hupenyu hwekushanda hwesimba rekumanikidza chisimbiso hwakapetwa ka5-10 kupfuura hwezvakajairwa zvigadzirwa zvekuisa chisimbiso cherabha, kusvika kumakumi enguva.Pasi pemamwe mamiriro ezvinhu, inogona kuve nehupenyu hwakafanana neiyo yekuisa chisimbiso matrix..Kupokana kwekupokana kweO-ring idiki, uye dhizaini uye static friction yakaenzana, inova 1/2-1/4 yekupokana kwe "0"-yakaumbwa rubber ring, inogona kubvisa "kukambaira" chiitiko. yepasi-speed uye low-pressure movement.Iyo O-ring inomira zvakanyanya kupfeka, uye ine otomatiki elastic muripo wekuita mushure mekupfeka chisimbiso.MaO-rings ane yakanaka self-lubricating properties.Inogona kushandiswa sechisimbiso chisina mafuta-isina lubrication.Iyo O-ring ine chimiro chakareruka uye iri nyore kuisa.O-mhete kushanda kumanikidza: 0-300MPa;kushanda kumhanya: ≤15m/s;kushanda tembiricha: -55-250 madhigirii.O-mhete inoshanda svikiro: hydraulic mafuta, gasi, mvura, dope, mafuta asina kuchena, emulsion, mvura-glycol, asidhi.
Zvakanakira zveO-rings:Zvichienzaniswa nemamwe marudzi ezvindori zvekuisa chisimbiso, O-mhete dzine zvinotevera zvakanakira: Inokodzera mafomu ekuisa chisimbiso akasiyana-siyana: static sealing, dynamic sealing, inokodzera zvinhu zvakasiyana-siyana, hukuru uye grooves zvakagadziriswa, zvinoshandurana Zvakasimba, zvakakodzera kune zvakasiyana-siyana zvekufamba modes. : rotary motion, axial reciprocating motion kana kusanganiswa kwekufamba (sekutenderera kutenderedza kwakasanganiswa kufamba), kwakakodzera kwakasiyana siyana yekuisa chisimbiso media: oiri, mvura, gasi, makemikari media kana imwe midhiya yakasanganiswa, nekusarudza yakakodzera Advanced rubber zvinhu uye zvakakodzera. Formula dhizaini inogona kuwana inoshanda yekuisa chisimbiso pamafuta, mvura, mweya, gasi uye akasiyana makemikari media.Iyo tembiricha yemhando yakafara (- 60 ℃ ~ + 220 ℃), uye kumanikidza kunogona kusvika 1500Kg/cm2 mukushandiswa kwakagadziriswa (inoshandiswa pamwe chete nemhete yekusimbisa).Iyo dhizaini iri nyore, chimiro chakabatana, uye gungano uye disassembly zviri nyore.Iyo yemuchinjikwa-chikamu chimiro cheO-ring chakareruka zvakanyanya, uye ine yekuzvivharira basa, uye yekuisa chisimbiso yakavimbika.Sezvo chimiro cheO-ring pachayo uye chikamu chekuisa chiri nyore uye chakamisikidzwa, zviri nyore kwazvo kuisa nekutsiva.Kune marudzi akawanda ezvigadzirwa: unogona kusarudza zvinoenderana nemvura dzakasiyana: kune nitrile rabha (NBR), fluorine rabha (FKM), silicone rabha (VMQ), ethylene propylene rabha (EPDM), neoprene rabha (CR), butyl rabha. (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), zvichingodaro, ine mutengo wakaderera uye idiki diki dhizaini kuramba.
