Tshooj Lus Taw Qhia
O-rings leaks yog ib qho ntawm ntau tshaj - thiab kim heev - sealing teeb meem hauv kev lag luam, kav dej, tsheb, thiab kev siv dej. Lub nplhaib O- leaking tej zaum yuav zoo li qhov teeb meem me me, tab sis nws feem ntau ua rau cov khoom siv poob qis, dej poob, kev pheej hmoo kev nyab xeeb, thiab cov nqi kho dua.
Txoj xov zoo? Feem ntau O- lub nplhaib tawm tuaj yeem tiv thaiv tau.
Hauv phau ntawv qhia no, peb piav qhiayuav ua li cas kom tsis txhob O-nplhaib los ntawm tosiv cov ntaub ntawv pov thawj engineering, tiag -cov ntaub ntawv hauv ntiaj teb, thiab kev ua tau zoo los ntawm aTuam Tshoj kev cai O-rings chaw tsim tshuaj pauspab thoob ntiaj teb OEM thiab ODM cov neeg siv khoom. Seb koj yuav khoomkev cai roj hmab O-rings, tsim cov khoom tshiab, lossis teeb meem kev xau hauv thaj chaw, kab lus no yuav muab cov lus teb meej rau koj.

Ntau tshaj70% ntawm O-ring tsis ua haujlwmtsis yog los ntawm cov roj hmab nws tus kheej, tab sis los ntawm kev xaiv tsis raug, qhov loj me, lossis kev teeb tsa.
Common leakage ua rau muaj xws li:
- Cov khoom siv tsis raug rau qhov kub thiab txias
- Tsis yog O-ntiv nplhaib loj lossis zawj tsim
- Tshaj - compression lossis qis dua - compression
- Tsis zoo nto tag los yog puas grooves
- Tshuaj o los yog khoom degradation
- Kev siv tsis raug lubrication lossis qhuav installation
Kev txwv tsis pub xau pib nrog kev nkag siab cov hauv paus hauv paus.
Kev xaiv cov khoom siv yog lub hauv paus ntawm kev tiv thaiv dej. Cov roj hmab sib txawv coj txawv txawv nyob rau hauv tshav kub, siab, thiab tshuaj lom neeg raug.
Hom O-Ring Materials thiab Applications
| Khoom siv | Qhov kub thiab txias | Qhov Zoo Tshaj Plaws | Tej kev siv |
|---|---|---|---|
| NBR (Nitrile) | -40℃rau 120 degree | Roj tsis kam, nqi -zoo | Hydraulic systems, tsheb |
| EPDM | -50℃rau 150 degree | Dej & dej tsis kam | Haus dej, da dej |
| Silicone (VMQ) | -60℃rau 200 degree | Flexibility, zaub mov -qib | Kev kho mob, khoom noj khoom haus |
| FKM (Viton®) | -20℃rau 250 degree | Tshuaj & kub tsis kam | Roj, tshuaj |
| FFKM | Mus txog 300 degree | Cov tshuaj tiv thaiv tsis zoo | Aerospace, semiconductor |
Raws li ib tugkev cai O-rings manufacturers, peb feem ntau pab cov neeg yuav khoom kho cov khoom sib txuas kom sib npaug ntawm tus nqi, lub neej ntev, thiab kev ua haujlwm.
Ib lub nplhaib O- uas yog txawm0.1mm tawmtuaj yeem xau.
Qhov loj me tseem ceeb muaj xws li:
- Sab hauv Diameter (ID)
- Hla -Section (CS)
- Groove dav thiab qhov tob
Pom zoo Compression Ratio
| Hom ntawv thov | Compression (%) |
|---|---|
| Static foob | 20% – 30% |
| Dynamic foob | 10% – 20% |
Compression ntau dhau ua rau muaj kev laus thaum ntxov. Tsawg compression tso cai rau cov dej bypass.
Txawm tias hwm O-rings yuav ua tsis tau yog tias ntsia tsis raug.
Qhov zoo tshaj plaws installation cov kauj ruam:
- Tshawb xyuas O-ntiv nplhaib kom pom qhov tsis xws luag
- Ntxuav cov groove thiab mating nto
- Siv cov roj nplua nyeem sib xws
- Tsis txhob sib tw los yog ncab
- Xyuas kom lub rooj zaum tsis sib xws hauv qhov zawj
Tsis txhob yuam O- ntiv nplhaib rau hauv txoj hauj lwm - kev puas tsuaj feem ntau pom tsis tau tab sis ua rau tuag taus.
Lubrication txo kev sib txhuam, tiv thaiv kev tsim kua muag, thiab txhim kho kev sib khi.
| O-Ring Material | Pom zoo Lubricant |
|---|---|
| NBR | Silicone roj (qib sib xws) |
| EPDM | Glycerin lossis dej -raws li lube |
| Silicone | Silicone- tsis muaj roj |
| FKM | PTFE-raws li lubricant |
Kev siv cov roj nplua nyeem tsis raug tuaj yeem ua rau o thiab tawm hauv lub lis piam.
Txawm tias lub nplhaib zoo meej O- tsis tuaj yeem foob rau qhov chaw ntxhib.
Pom zoo nto roughness:
- Static seals:0.8-1.6 hli
- Dynamic seals:0.4-0.8 hli
Kos, burrs, lossis cov cim cuab yeej tsim micro- txoj hauv kev tawm hauv siab.
Kub hloov pauv cuam tshuam rau roj hmab elasticity. Kev ntxhov siab cuam tshuam rau deformation.
- Kub kub → compression teeb
- Tsawg kub → hardening thiab tawg
- Kev kub siab → extrusion txaus ntshai
Ib txwm tsim cov ntsaws ruaj ruaj raucov kev ua haujlwm siab tshaj plaws, tsis yog tus nqi nruab nrab.
Chemical incompatibility yog ib qho uas ntsiag to tua neeg.
Cov teebmeem muaj xws li:
- o (txog 30% ntim nce)
- Brittleness
- Poob lub zog tensile
Nco ntsoov txheeb xyuas cov khoom sib haum nrogmedia + kub + siab- tsis yog ib yam xwb.
Kev cia tsis raug ua kom luv O-ntiv nplhaib lub neej ua ntej siv.
Cov txheej txheem khaws cia:
- Txias, qhuav, tsaus ntuj
- Tawm ntawm ozone, UV, thiab cov kuab tshuaj
- Tsis hnyav stacking
- Khaws nyob rau hauv thawj ntim
Txee lub neej tseem ceeb, tshwj xeeb tshaj yog rau cov khoom siv silicone thiab EPDM.
Kev tiv thaiv kev hloov pauv nqi tsawg dua li qhov tsis tau npaj tseg.
Daim ntawv tshuaj ntsuam xyuas:
- Nto tawg los yog flattening
- Poob elasticity
- Tshuaj o
- Groove puas
Rau cov txheej txheem tseem ceeb, tuav afoob hloov log.
Yog hais tias lub nplhaib O- leak, nug:
- Cov khoom puas yog?
- Puas yog qhov loj me?
- Puas yog nws lubricated zoo?
- Puas yog qhov zawj puas lawm?
- Puas yog kub lossis tshuaj lom neeg tawm ntawm qhov chaw?
Standard O-rings tsis haum rau txhua daim ntawv thov.
Kev cai O-rings tso cai:
- Optimized compound formulation
- Tight dimensional tolerances
- Daim ntawv thov -kev ua haujlwm tshwj xeeb
- Lub neej ua haujlwm ntev dua
Qhov no yog vim li cas ntau lub lag luam thoob ntiaj teb koom tes nrog aTuam Tshoj kev cai O-rings chaw tsim tshuaj pausrau ODM kev daws teeb meem.
Q1: Kuv puas tuaj yeem rov siv dua O- nplhaib tom qab disassembly?
Tsis yog. Reused O-rings muaj compression teeb thiab muaj feem yuav xau ntau dua.
Q2: Vim li cas kuv lub nplhaib O- tsuas yog thaum kub kub?
Cov khoom softening lossis compression teeb yog qhov ua rau.
Q3: Puas yog lubrication nres nres mus tas li?
Lubrication pab, tab sis cov khoom siv thiab qhov loj me yog qhov tseem ceeb.
Q4: Puas yog silicone O-rings zoo rau kev kub siab?
Silicone yog hloov tau tab sis tsis zoo tagnrho rau siab -siab dynamic seals.
