Lub Hwj Chim Hydraulic Oring

Loj: Standard thiab Customized

Khoom siv: Nitrile / NBR / Buna, FKM / FPM, Silicone, EPDM, HNBR, NR, FFKM, FEPM, thiab lwm yam.

Cov khoom siv hluav taws xob hydraulics Oring yog dab tsi

Thaum tsis muaj hydraulic siab, qhov elastic contact nto ntawm O-ring generates pre contact pressure kom ua tiav thawj sealing. Tom qab lub sealing chamber yog ntim nrog roj siab, nyob rau hauv qhov kev txiav txim ntawm hydraulic siab, lub O-ring squeezes ntawm ib sab ntawm lub zawj, thiab kev sib cuag ntawm lub sealing nto nce, kev txhim kho sealing nyhuv.

Thaum txhim kho txhua yam ntawm lub nplhaib sealing, nws yog ib qho tsim nyog los xyuas kom meej qhov tsim nyog ua ntej compression shrinkage. Yog tias nws me dhau, nws tsis tuaj yeem kaw. Yog tias nws loj dhau, nws yuav ua rau muaj kev sib txhuam thiab yooj yim puas. Yog li ntawd, qhov zawj me me thiab qhov tseeb ntawm qhov chaw rau kev txhim kho lub nplhaib sealing yuav tsum tau lees paub nruj me ntsis raws li cov ntaub ntawv muab rau hauv phau ntawv uas cuam tshuam.

Nyob rau hauv dynamic sealing, thaum lub siab siab tshaj 10MPa, O-ring yuav raug nyem rau hauv qhov sib txawv thiab puas. Yog li ntawd, PTFE los yog nylon tuav lub nplhaib ua los ntawm PTFE los yog nylon yuav tsum tau ntsia rau ntawm qhov qis-siab ntawm O-ring, nrog ib tug tuab ntawm 1.25 ~ 2.5mm. Thaum raug kev kub siab nyob rau hauv ob qho tib si kev taw qhia, tuav lub nplhaib yuav tsum tau ntxiv rau ntawm ob sab.

Kev xaiv hom 0 sealing zaub cov khoom yog qhov tseem ceeb rau nws txoj kev sib khi thiab kev pabcuam lub neej. Kev ua haujlwm ntawm cov khoom siv ncaj qha cuam tshuam rau kev ua haujlwm ntawm O-ring. Ntxiv rau cov kev cai dav dav rau cov khoom siv sib khi, O-ring yuav tsum tau ua tib zoo saib xyuas cov xwm txheej hauv qab no:

(1) Kev nplua nuj nyob rau hauv elasticity thiab resilience

(2) Tsim nyog txhua yam muaj zog, suav nrog lub zog nthuav dav, elongation, thiab tsim kua muag

(3) Kev ua haujlwm ruaj khov, tsis tshua muaj o nyob rau hauv nruab nrab, thiab thermal shrinkage nyhuv (Joule effect)

(4) Yooj yim rau txheej txheem thiab cov duab, thiab muaj peev xwm tswj tau qhov ntev

(5) Tsis muaj corrosive qhov chaw, tsis muaj kuab paug tawm, thiab lwm yam.
