PTFE Tiiso

Li-radial shaft seals tse nang le molomo o le mong kapa ho feta oa PTFE sealing (s) li etselitsoe ho mamella maemo a mabifi, mocheso o phahameng, likhatello tse phahameng le ho omella hoo litiiso tse tloaelehileng tsa radial shaft tse entsoeng ka lisebelisoa tsa molomo tse koalang elastomeric li ke ke tsa mamella.Metsoako e mengata ea PTFE e amohetsoe ke FDA.

Melemo ea mantlha ea litiiso tsa PTFE li kenyelletsa:

Ho hanyetsa lik'hemik'hale tse phahamengHo mamella lebelo la ho fihla ho 30 m/s (5 900 ft/min)Mocheso o pharalletseng oa ho sebetsa, -70 ho ea ho +250 °C (-95 ho +480 °F)Hanela likhatello tse fihlang ho 3,5 MPa (500 psi) Mamella ho matha o omileng

Khetho ea lisebelisoa tsa tiiso hangata e hloka ho sekisetsa lipakeng tsa melemo le melemo.Ho na le lisebelisoa tse makholo tse fapaneng tsa PTFE tse nang le mefuta e fapaneng ea li-filler.Li-filler tse tloaelehileng li kenyelletsa fiber ea khalase, khabone, graphite, molybdenum disulphide, li-oxide tsa tšepe le li-polymer tse fapaneng.E 'ngoe le e' ngoe e na le thepa e fapaneng, e loketseng lits'ebetso tse fapaneng le maemo a ts'ebeletso.E tloaelehileng ho lisebelisoa tsohle tsa PTFE tse tlatsitsoeng ke khanyetso ea tsona e ntlafalitsoeng ea ho roala le ho senyeha.

PTFE e sa tlatsoang e fana ka, maemong a mangata, coefficient e tlase ea khohlano ho feta thepa e tlatsitsoeng ea PTFE le boemo bo tlase ba ho roala ha sefahleho sa tiiso.Leha ho le joalo, molomo o koalang o entsoeng ka thepa e sa tlatsoang ea PTFE o na le khanyetso e fokolang ea ho roala le ho senyeha tlas'a mojaro.

Lisebelisoa tsa PTFE tseo SKF e li khothalletsang hangata li thathamisitsoe tafoleng.Ntle le metsoako e thehiloeng ho PTFE, SKF e boetse e fana ka litiiso tsa radial shaft ka li-plastiki tse ling tse fetotsoeng, tse ling tsa tsona li thathamisitsoe tafoleng.

Ho khetha thepa e nepahetseng bakeng sa nyeoe ea tšepe le li-O-ring (s) le tsona ke tsa bohlokoa haholo ho fihlela ts'ebetso e khotsofatsang ea ho tiisa.Ikopanye le SKF bakeng sa lintlha tse ling.
