Radial shaft seals ine imwechete kana kupfuura PTFE sealing lip (s) yakagadzirirwa kutsungirira nharaunda dzine hutsinye, tembiricha yakakwira, kudzvanywa kwakanyanya uye kuoma kumhanya izvo zvechinyakare radial shaft zvisimbiso zvakagadzirwa ne elastomeric sealing lip zvinhu hazvigone kumira.Mazhinji emakomisheni ePTFE akatenderwa neFDA.
Mabhenefiti makuru ePTFE zvisimbiso anosanganisira:
High chemical resistanceKumira kunomhanya kusvika 30 m/s (5 900 ft/min) Kubata tembiricha yakafaranuka, -70 kusvika +250 °C (-95 kusvika +480 °F)Kushingirira kumanikidzwa kusvika ku3,5 MPa (500 psi) Kutsungirira yakaoma kumhanya
Kusarudzwa kwezvinhu zvechisimbiso zvinowanzoda kubvumirana pakati pezvakanakira uye zvisingabatsiri.Kune mazana ezvakasiyana PTFE zvinhu zvine akasiyana mafirita.Mafirita akajairwa anosanganisira girazi fiber, kabhoni, graphite, molybdenum disulphide, simbi oxides uye akasiyana mapolymer.Imwe neimwe ine zvivakwa zvakasiyana, inokodzera akasiyana maapplication uye sevhisi mamiriro.Zvakajairwa kune ese akazadzwa PTFE zvinhu ndiko kukwidziridzwa kwavo kuramba kupfeka uye deformation.
PTFE isina kuzadzwa inopa, kazhinji, yakaderera coefficient yekukwesha pane yakazadzwa PTFE zvinhu uye yakaderera dhigirii yekupfeka kwechisimbiso counterface.Nekudaro, muromo wekuvhara wakagadzirwa neiyo isina kuzara PTFE zvinhu ine kushoma kuramba kupfeka uye deformation pasi pemutoro.
Zvishandiso zvePTFE zvinonyanya kukurudzirwa neSKF zvakanyorwa patafura.Pamusoro pePTFE-based compounds, SKF inopawo radial shaft seals mune mamwe mapurasitiki akagadziridzwa, mamwe acho akanyorwa patafura.
Kusarudza zvinhu zvakakodzera zvekesi yesimbi uye maO-ring (s) zvakare zvakakosha zvakakosha kuti uwane inogutsa yekuisa chisimbiso kuita.Bata SKF kuti uwane rumwe ruzivo.
