Radial shaft seals nrog ib los yog ntau tshaj PTFE sealing di ncauj yog tsim los tiv thaiv ib puag ncig aggression, kub kub, siab siab thiab qhuav khiav uas tsoos radial ncej ntsaws ruaj ruaj ua los ntawm elastomeric sealing daim di ncauj tsis tuaj yeem tiv taus.Ntau yam ntawm PTFE compounds yog FDA pom zoo.
Qhov zoo ntawm PTFE seals muaj xws li:
Cov tshuaj lom neeg muaj zog tiv taus siab txog li 30 m / s (5 900 ft / min) Kev khiav hauj lwm kub ntau, -70 txog +250 ° C (-95 txog +480 ° F) Nrog rau siab txog 3.5 MPa (500 psi) Tiv thaiv kom qhuav
Kev xaiv cov ntaub ntawv foob feem ntau yuav tsum muaj kev sib haum xeeb ntawm qhov zoo thiab qhov tsis zoo.Muaj ntau pua cov ntaub ntawv PTFE sib txawv nrog ntau yam khoom siv.Feem ntau cov khoom muaj xws li iav fiber, carbon, graphite, molybdenum disulphide, hlau oxides thiab ntau yam polymers.Txhua tus muaj cov khoom sib txawv, tsim nyog rau kev siv sib txawv thiab kev pabcuam.Feem ntau rau tag nrho cov ntaub ntawv PTFE puv yog lawv txhim kho kev hnav thiab deformation.
Unfilled PTFE muab, feem ntau, qis coefficient ntawm kev sib txhuam dua li cov khoom siv PTFE puv thiab qhov qis tshaj ntawm hnav ntawm lub foob counterface.Txawm li cas los xij, daim di ncauj sealing ua los ntawm cov khoom tsis muaj PTFE muaj kev txwv tsis pub hnav thiab deformation nyob rau hauv load.
PTFE cov ntaub ntawv uas SKF feem ntau pom zoo muaj nyob rau hauv lub rooj.Ntxiv nrog rau PTFE-based compounds, SKF kuj tseem muaj cov ntsaws ruaj ruaj radial hauv lwm cov yas hloov kho, qee qhov tau teev nyob rau hauv lub rooj.
Xaiv cov khoom tsim nyog rau rooj plaub hlau thiab O-ring (s) kuj tseem ceeb heev rau kev ua tiav kev sib khi zoo.Hu rau SKF yog xav paub ntxiv.
