O-rings (O-rings)yog cov roj hmab sealing nplhaib nrog ib ncig hla ntu.Vim nws O-shaped cross section, nws hu ua O-ring, kuj hu ua O-ring.Nws pib tshwm sim nyob rau hauv nruab nrab ntawm lub xyoo pua 19th, thaum nws tau siv los ua ib qho kev sib khi rau lub tog raj kheej lub tog raj kheej.
O-ringsFeem ntau yog siv rau static sealing thiab reciprocating motion sealing.Thaum siv rau kev sib txuas lus sib txuas, nws tsuas yog siv rau cov khoom siv qis-ceev rotary sealing.Lub O-ring feem ntau yog ntsia rau hauv ib qho zawj nrog lub voj voos hla ntawm lub voj voog sab nrauv lossis lub voj voog sab hauv los ua lub luag haujlwm sib khi.O-ring seals tseem ua lub luag haujlwm zoo hauv kev sib khi thiab kev poob siab nyob rau hauv ib puag ncig xws li roj tsis kam, acid thiab alkali, puas, thiab tshuaj yaig.
O-ring nta:O-ring muaj kev sib khi zoo heev thiab ua haujlwm ntev.Lub neej ua haujlwm ntawm dynamic siab foob yog 5-10 lub sij hawm siab dua li cov khoom siv roj hmab sealing, txog li kaum ob zaug.Nyob rau hauv tej yam kev mob, nws muaj peev xwm muaj tib lub neej raws li lub sealing matrix..Kev sib txhuam ntawm O-ntiv nplhaib yog me me, thiab kev sib txhuam dynamic thiab zoo li qub yog sib npaug, uas yog 1/2-1/4 ntawm kev sib txhuam ntawm "0"-zoo li lub nplhaib roj hmab, uas tuaj yeem tshem tawm qhov tshwm sim "crawling" ntawm qis-ceev thiab tsis tshua muaj zog txav.Lub O-ring yog hnav-tiv taus, thiab muaj qhov tsis siv neeg elastic nyiaj ua haujlwm tom qab lub sealing nto yog hnav.O-rings muaj cov khoom zoo ntawm tus kheej lubricating.Yuav siv tau los ua roj-dawb lubrication foob.O-ring muaj cov qauv yooj yim thiab yooj yim rau nruab.O-ring ua haujlwm siab: 0-300MPa;Ua haujlwm ceev: ≤15m / s;Ua haujlwm kub: -55-250 ℃.O-ring siv nruab nrab: hydraulic roj, roj, dej, av nkos, roj crude, emulsion, dej-glycol, acid.
Qhov zoo ntawm O-rings:Piv nrog rau lwm hom sealing rings, O-rings muaj qhov zoo hauv qab no: Haum rau ntau hom sealing: static sealing, dynamic sealing, haum rau ntau yam ntaub ntawv, qhov ntau thiab tsawg thiab grooves tau standardized, interchangeable Strong, haum rau ntau hom kev txav. : rotary motion, axial reciprocating motion lossis kev sib xyaw ua ke (xws li cov lus teb reciprocating ua ke), haum rau ntau yam sib txawv sealing media: roj, dej, roj, tshuaj lom neeg los yog lwm yam khoom sib xyaw, los ntawm kev xaiv cov khoom siv roj hmab uas tsim nyog thiab tsim nyog. Cov qauv tsim tuaj yeem ua tiav cov txiaj ntsig zoo ntawm cov roj, dej, cua, roj thiab ntau yam tshuaj lom neeg.Qhov ntsuas kub yog qhov dav (- 60 ℃ ~ + 220 ℃), thiab lub siab tuaj yeem ncav cuag 1500Kg / cm2 hauv kev siv tas li (siv ua ke nrog lub nplhaib txhawb nqa).Tus qauv tsim yog yooj yim, cov qauv yog compact, thiab kev sib dhos thiab disassembly yog yooj yim.Tus ntoo khaub lig-section qauv ntawm O-ring yog yooj yim heev, thiab nws muaj ib tug self-sealing muaj nuj nqi, thiab sealing kev ua tau zoo yog txhim khu kev qha.Txij li cov qauv ntawm O-ring nws tus kheej thiab qhov kev teeb tsa yog qhov yooj yim heev thiab tus qauv, nws yooj yim heev rau nruab thiab hloov.Muaj ntau yam khoom siv: koj tuaj yeem xaiv raws li cov kua dej sib txawv: muaj cov roj hmab nitrile (NBR), fluorine roj hmab (FKM), silicone roj hmab (VMQ), ethylene propylene roj hmab (EPDM), neoprene roj hmab (CR), butyl roj hmab (BU), polytetrafluoroethylene (PTFE), roj hmab ntuj (NR), thiab lwm yam, nrog tus nqi qis thiab kuj me me dynamic kev sib txhuam.

O-ring Scope ntawm daim ntawv thov: O-rings yog tsim rau kev teeb tsa ntawm ntau yam khoom siv kho tshuab, thiab ua lub luag haujlwm sib khi hauv lub xeev zoo li qub lossis txav mus raws li qhov ntsuas kub, siab, thiab cov kua thiab roj sib txawv.Ntau hom kev foob yog siv dav hauv cov cuab yeej siv tshuab, nkoj, tsheb, tsheb, khoom siv aerospace, metallurgical machinery, chemical machinery, engineering machinery, engineering machinery, build machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, thiab ntau yam cuab yeej thiab meters.keeb.O-rings feem ntau yog siv rau kev sib khi zoo li qub thiab kev sib txuas lus sib txuas.Thaum siv rau kev sib txuas lus sib txuas, nws tsuas yog siv rau cov khoom siv qis-ceev rotary sealing.Lub O-ring feem ntau yog ntsia rau hauv ib qho zawj nrog lub voj voos hla ntawm lub voj voog sab nrauv lossis lub voj voog sab hauv los ua lub luag haujlwm sib khi.O-ring seals tseem ua lub luag haujlwm zoo hauv kev sib khi thiab kev poob siab nyob rau hauv ib puag ncig xws li roj tsis kam, acid thiab alkali, puas, thiab tshuaj yaig.Yog li ntawd, O-ring yog qhov siv dav tshaj plaws hauv hydraulic thiab pneumatic kis tau tus mob.
