[2026-04-03]|Los ntawm Xiamen Jinshun Sealing Technology Co., Ltd. Annie Xu

O-rings nyob txhua qhov chaw-hauv li qub, twj tso kua mis, cav, thiab cov tshuab dej. Tej zaum lawv yuav zoo li yooj yim, tab sis thaum lawv ua tsis tiav, tus nqi tuaj yeem loj heev: kev xau, kev poob qis, lossis txawm tias muaj kev nyab xeeb.

Phau ntawv qhia no rhuav tshem yuav ua li cas O-rings tiag tiag foob, hom tsis ua haujlwm feem ntau, thiab yuav tiv thaiv lawv li cas. Yog tias koj tab tom nrhiav los ntawm akev cai O-rings manufacturerslos yog tsim cov tshuab sealing, qhov no yog qhov kev paub zoo uas koj xav tau kom tsis txhob raug nqi ntau.

Lub nplhaib O- yog lub voj voog elastomer foob nrog ib puag ncig hla- ntu. Nws yog dav siv vim nws yog:

• Tus nqi qis
• Yooj yim rau nruab
• Muaj kev ntseeg siab nyob rau hauv cov xwm txheej zoo

Tus qauv O- nplhaib loj yog txhais los ntawm:

• Sab hauv Diameter (ID)
• Hla ntu (CS)

Piv txwv li:20 × 2.4 hlitxhais tau tias 20 mm ID thiab 2.4 mm thickness.

Cov qauv thoob ntiaj teb suav nrog:

• AS 568 (USA)
• ISO 3601 (International)
• JIS (Nyiv)

Lub hauv paus ntsiab lus sealing yog qhov tseeb ncaj nraim.

Thaum ntsia hauv qhov zawj, O- nplhaib yogcompressed (feem ntau 15-30%), tsim kev sib cuag thawj zaug ntawm ob qhov chaw mating.

Raws li qhov system siab nce:

• O- nplhaib deforms ntxiv
• Kev sib cuag siab nce tau
• Txoj kev ntws tawm raug thaiv

👉 Hauv cov ntsiab lus yooj yim:qhov siab dua, qhov zoo dua lub foob- nyob rau hauv kev txwv tsim.

Cov ntawv thov sib txawv xav tau cov elastomers sib txawv. Xaiv cov khoom siv tsis raug yog ib qho ntawm qhov ua rau ua tsis tiav.

Cov ntaub ntawv sib piv

💡 Raudej haus los yog RO systems, zaub mov- qib silicone thiab EPDM nrog NSF/FDA ntawv pov thawj yog nyiam.

1. Kev puas tsuaj

Cov tsos mob:Txiav los yog nicks ntawm qhov chaw
Ua rau:Cov npoo ntse, cov cuab yeej tsis tsim nyog
Kho:Siv cov hmoov lead- hauv chamfers thiab lubrication

2. Twisting lossis kauv tsis ua haujlwm

Cov tsos mob:O-ntiv nplhaib zoo li twisted lossis spiraled
Ua rau:Kev sib txhuam + tsis tsim nyog zawj tsim
Kho:Siv cov roj nplua nyeem thiab ua kom zoo dua qhov kev ua siab ntev

3. Tshaj -Compression

Cov tsos mob:Flattened hla-section, tawg
Ua rau: Excessive squeeze (>30%)
Kho:Redesign groove qhov ntev

4. Extrusion (Nibbling)

Cov tsos mob:Cov npoo ntxhib ntawm qis - siab
Ua rau:Kev kub siab + loj clearance sib txawv
Kho:Siv cov nplhaib thaub qab lossis cov khoom siv tawv dua

5. Compression Set

Cov tsos mob:Permanent deformation, poob ntawm elasticity
Ua rau:Kub kub lossis khoom siv tsis zoo
Kho:Siv cov ntaub ntawv compression tsawg (piv txwv li, FKM, HNBR)

6. Tshuaj degradation

Cov tsos mob:o, tawg, discoloration
Ua rau:Cov xov xwm tsis sib xws
Kho:Muab cov khoom siv rau ib puag ncig chemical

7. Thermal Cracking

Cov tsos mob:Nto tawg, hardening
Ua rau:Tshaj kub los yog thermal cycling
Kho:Xaiv qhov siab -kub elastomers

8. Abrasive Hnav

Cov tsos mob:Nto hnav cov khoom
Ua rau:Lub lubrication tsis zoo los yog muaj kab mob
Kho:Txhim kho qhov chaw tiav (Ra tsawg dua lossis sib npaug rau 0.8 μm pom zoo)

9. Hluav taws xob lossis hluav taws xob puas tsuaj

Cov tsos mob:Hmoov residue, discoloration
