Dab tsi yog Encapsulated O-ring?
Ib qho encapsulated O-ring yog ib qho tshwj xeeb foob ua los ntawm kev sib xyaw ntawm ob cov ntaub ntawv, muaj ob qhov loj, piv txwv li, lub tsho sab nrauv thiab cov tub ntxhais sab hauv.Cov ntsaws ruaj ruaj no feem ntau siv nyob rau hauv ob qho tib si kev lag luam thiab hauv tsev kom tsis txhob tso pa tawm ntawm huab cua, roj, lossis kua dej los ntawm cov pob qij txha.
Cov seals no muab kev yooj yim ntxiv, kev ua siab ntev, ruaj khov, thiab tshuaj lom neeg thiab kub ua haujlwm. Txawm hais tias koj tuaj yeem siv txhua hom roj hmab O-ntiv nplhaib los yog foob los ua txoj haujlwm, siv lub nplhaib O-ring muaj nws cov txiaj ntsig ntxiv.
Ob-txheej o-ntiv nplhaib yog ua los ntawm cov tsho tiv no, uas feem ntau yog cov khoom siv hu ua Teflon, thiab cov tub ntxhais sab hauv, uas yog silicone lossis Viton. Cov khoom siv sab nrauv Teflon encapsulates lub hauv paus, yog li muab lub npe Teflon encapsulated O-rings.
Hom Encapsulated O-ring
Txawm hais tias lub hom phiaj ntawm tag nrho cov encapsulated O-rings yuav luag zoo ib yam, muaj qhov sib txawv me me hauv lawv cov khoom tsim thiab tsim, uas ua rau lawv txoj haujlwm tshwj xeeb me ntsis.
Hollow core O-rings thiab Solid core O-rings yog ob hom Encapsulated O-rings raws li lawv cov qauv tsim.Muaj ob peb lwm hom O-rings nyob ntawm seb cov khoom siv hauv lub tsho sab nrauv thiab cov tub ntxhais sab hauv, txhua tus nrog nws cov yam ntxwv tshwj xeeb.
Khoom Core
Cov tub ntxhais tseem ceeb O-rings tshwj xeeb yog tsim los daws qhov kub thiab txias. Nws yog vim tias lawv cov tub ntxhais sab hauv tau ntim nrog cov khoom siv hu ua Silicone lossis Viton, zoo li lub log tsheb ntawm lub tsheb kauj vab tsis muaj tube. Cov tub ntxhais tseem ceeb O-rings muab kev sib cog lus zoo thiab hloov tau yooj yim, ua rau lawv xaiv qhov zoo tshaj plaws rau kev siv hauv Frigid kub.
Cov khoom tseem ceeb kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov yam ntxwv zoo ntawm cov khoom siv O-ring encapsulated. Viton inner core O-ring yog paub zoo txog nws qhov yooj thiab shrinking peev xwm, thaum Silicone inner core O-ring yog nto moo rau nws cov tshav kub-resistant peev xwm. Cov tub ntxhais tseem ceeb encapsulated O-ring muaj npe nrov rau nws tuav elasticity.
Hollow Core
Hollow core o-rings, raws li lub npe qhia, yog hollow los ntawm sab hauv, zoo li cov tsheb kauj vab inflatable.Hollow core O-rings zoo ib yam li cov tub ntxhais O-rings zoo li ob qho tib si muaj lub tsho sab nrauv ua los ntawm Teflon uas encapsulates cov tub ntxhais sab hauv, tshwj tsis yog qhov qub yog hollow los ntawm sab hauv.
Lub tsho sab nrauv yog ua los ntawm PFA lossis FEP, nyob ntawm qhov yuav tsum tau ua thiab cov xwm txheej nws yuav tsum muaj sia nyob hauv. Ntawm qhov tod tes, cov tub ntxhais sab hauv yog FKM (ua los ntawm Viton) lossis silicone, muab nws lub peev xwm tshwj xeeb los nyem. rau hauv qhov chaw nruj. Txawm li cas los xij, xws li O-rings tawm tsam nrog kev rov qab los tom qab kev cog lus.
FEP
FEP nthuav dav raws li Fluorinated Ethylene Propylene, tsis yog hom encapsulated O-ring tab sis ib qho khoom siv tshwj xeeb uas ua rau hom tshwj xeeb ntawm encapsulated O-ring. Feem ntau cov neeg tsis meej pem nrog Teflon, uas yog lwm yam khoom siv nyob rau hauv txheej txheej ntawm lub encapsulated O-rings.FEP tseem muaj ntau lub npe hauv kev lag luam, xws li Neoflon FEP, Teflon FEP, thiab Dyneon FEP.
Ntau yam ntawm FEP-coated O-rings muaj xws li tsis tshua muaj kev sib txhuam thiab tsis kam mus rau qhov kub thiab txias xws li -60 degree mus rau +205 degree . Nws kuj tseem tuaj yeem hloov pauv tau ntawm qhov kub thiab txias, uas qhia txog kev ua haujlwm zoo ntawm cov foob pob hluav taws. Tsis tas li ntawd, nws tseem muaj peev xwm tiv taus cov tshuaj corrosive dua li tsis yog-flammable.
FEP muaj cov txheej txheem compression tsawg heev, uas qhia tau hais tias nws tuaj yeem rov qab los rau nws cov duab qub tom qab deformation. Cov khoom siv no tuaj yeem pab tsim ntau hom O-rings, xws li FEP encapsulated khoom silicone, FEP encapsulated steel caij nplooj ntoos hlav, thiab FEP encapsulated hollow silicone.
Nitrile Elastomer
Yog tias koj tab tom nrhiav ib lub hnab ntim O-ring rau kev siv, xws li kev sib khi cov pob qij txha uas cuam tshuam nrog dej, roj, lossis cov kua dej hydraulic, ces Nitrile Elastomer yog qhov koj xaiv. Kuj tseem hu ua Buna-N lossis NBR, Nitrile Elastomer yog lub nplhaib dav dav feem ntau siv rau qhov kub ntawm -50 degree txog 120 degree .
Txawm hais tias nws muaj kev tiv thaiv zoo rau qhov kub thiab txias thiab cov txheej txheem abrasive, muaj kev pheej hmoo siab ntawm kev puas tsuaj yog tias qhov kev txwv ntau dhau. Piv txwv li, cov khoom xws li ketones, nitrohydrocarbons, Phosphorus ester, thiab lwm yam, tuaj yeem ua rau lub nplhaib puas. Vim li no, nitrile elastomers tsuas yog tsim nyog rau kev siv tsawg hauv tsheb, kev tsheb ciav hlau, kev huv, thiab kev ua liaj ua teb.
Viton O-rings
Viton O-rings yog ib hom encapsulated O-rings nrog FKM lossis Viton core inner core.Lub tsho sab nrauv yuav yog PFA lossis FEP, nyob ntawm seb koj xav tau FEP-encapsulated Viton core lossis PFA-encapsulated Viton core.Cov no kuj muaj thermal stability zoo nyob rau hauv qhov kub ntawm -40 degree mus rau 250 degree .
Nyob rau hauv lub ntsiab lus, Viton O-rings muaj lub zog txhua yam, tsis tshua muaj compression teeb tsis kam, thiab tsis tshua muaj roj permeability. Cov yam ntxwv no ua rau nws xaiv zoo tshaj plaws rau tsheb, aerospace industries, thiab chemical engineering industries. Txawm hais tias lawv ua haujlwm zoo nrog roj av, acids, halogenated hydrocarbons, thiab silicone kua, ib tug yuav tsum tsis txhob sib cuag nrog rhuab hydrofluoric acids, esters, molecular hnyav amines, thiab Skydrol.
Silicone O-rings
Zoo ib yam li lwm cov ntaub qhwv O-rings, silicone O-rings muaj thermal stability zoo rau qhov kub thiab txias ntawm -100 degree mus rau 300 degree . Tsis tas li ntawd, Silicone O-rings 'tsim tshwj xeeb tsim cov tub ntxhais sab hauv muab qhov tshwj xeeb siab ntev mus txog -115 degree txog 315 degree rau qee lub sijhawm. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov cheeb tsam uas xav tau qhov kub thiab txias hloov pauv.
Zoo ib yam li lwm cov ntaub qhwv O-rings, Silicone O-rings kuj ua haujlwm zoo dua nrog cov ntawv thov zoo li qub. Tsis tas li ntawd, cov O-rings no tau qhuas rau lawv qhov yooj yim thiab muaj peev xwm ua kom puas. Txawm li cas los xij, lawv tsuas ua haujlwm zoo dua nrog dej, roj, thiab chav dej.Muaj ob hom Silicone O-rings: Hollow Silicone core thiab khoom silicone core.
Cov txiaj ntsig thiab kev txwv ntawm Encapsulated O-rings
Txog tam sim no, peb tau sib tham txog ntau hom kev ntim O-rings thiab lawv cov ntawv thov hauv kev lag luam sib txawv thiab cov xwm txheej. Nov yog qee qhov txiaj ntsig ntawm encapsulated O-rings uas ua rau lawv xaiv zoo dua li cov yas zoo tib yam lossis elastomeric foob.
- Tshwj xeeb thermal stability rau kub txog li 500 degrees Fahrenheit.
- Muaj nyob rau hauv cov duab sib txawv thiab ntau thiab tsawg raws li koj xav tau.

- Yooj yim heev thiab ruaj khov rau kev ntxhov siab
Cov no yog qee qhov zoo ntawm kev siv encapsulated O-rings es tsis txhob siv roj hmab ntsaws ruaj ruaj. Txawm li cas los xij, ntawm no yog qee qhov kev txwv uas koj yuav tsum paub ua ntej cuam tshuam nrog O-rings encapsulated.
- Feem ntau ntawm cov O-rings no ua haujlwm nrog cov ntawv thov zoo li qub.
- Koj yuav tsum tau kuaj xyuas cov khoom siv nrog ntau yam tshuaj
- Txhua hom muaj kev txwv kub, txawm hais tias qhov kev txwv yog siab heev.
Xaus
Encapsulated O-rings yog qhov tseem ceeb rau lawv cov yam ntxwv zoo hauv ntau qhov kev lag luam. Lawv tshwj xeeb endurance thiab compatibility nrog ntau yam tshuaj thiab gases ua rau lawv xaiv zoo meej. Txawm hais tias lawv muaj nyob rau hauv ntau qhov ntau thiab tsawg, cov duab los yog cylindrical yog tus qauv, uas yog yooj yim.
