Cov khoom siv roj hmab feem ntau siv rauhydraulic sealsyog nitrile roj hmab NBR.Tsis tas li ntawd, thaum muaj cov kev cai tshwj xeeb rau kev tiv thaiv tshav kub thiab roj, fluororubber tuaj yeem siv tau;Thaum muaj cov kev cai tshwj xeeb rau kev hnav tsis kam thiab siab tsis kam, AU / EU (polyurethane roj hmab) tuaj yeem xaiv.
1. Hom kev tshaj tawm ua haujlwm rau hydraulic seals
Puas yog qhov nruab nrab ua haujlwm ntawm hydraulic seals kua lossis roj?Yog tias nws yog kua, qhov sib xyaw ua ke ntawm cov kua thiab cov khoom yuav tsum raug txiav txim siab;Gas kuj yuav tsum tau xav txog kev sib raug zoo ntawm cov ntaub ntawv nrog lubricants thiab roj;Gas thiab tsis zoo siab sealing yuav tsum tau them sai sai rau breathability.Yog tias cov khoom siv sealing tau sib haum nrog cov kua sealing, nws tuaj yeem ua rau lub sealing lub ntsiab lus nthuav dav lossis kev cog lus, ua rau tsis ua haujlwm thaum pib ntawm kev siv.Kev nthuav dav ntawm lub foob ua rau muaj kev sib txhuam tsis sib haum thiab tseem ua rau lub foob yob.Shrinkage ntawm lub sealing caij tuaj yeem ua rau txo qis hauv preloading, txo qis hauv eccentricity them peev xwm, thiab thaum kawg ua rau to.
2. Dynamic lossis zoo li qub sealing
Dynamic seals muaj cov kev xav tau sib xws rau kev sib txhuam thiab hnav kev ua haujlwm ntawm cov khoom siv, thiab cov khoom siv nrog kev sib txhuam coefficient tsim nyog yuav tsum raug xaiv raws li qhov loj ntawm qhov nrawm nrawm.Txhawm rau kom ua tiav lub neej ua haujlwm txaus, nws tseem yuav tsum xaiv qhov hnav tsis kam ntawm cov ntaub ntawv raws li qhov nrawm thiab mob stroke ntawm kev txav.Thaum muaj qhov yuav tsum tau ua kom qis qis, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov loj ntawm cov khoom sib txhuam coefficient thiab qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov sib txawv.
3. Cov qauv ntawm cov khoom sib khi (extruded lossis di ncauj zoo li)
Lub hauv paus ntsiab lus ua haujlwm ntawm kev sib khi sib txawv nrog cov qauv sib txawv, uas inevitably xav tau cov khoom sib txawv xws li elasticity, lub zog, thiab deformation tus nqi ntawm cov ntaub ntawv.
4. Ua haujlwm kub ntawm hydraulic seals
Qhov ntsuas kub ntawm ntau yam sealing rubbers thiab plastics txawv heev.Thaum xaiv cov ntaub ntawv, nws yog ib qho tsim nyog yuav tsum tau ua kom raug qhov kub thiab txias ntawm cov khoom sib khi, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias ib puag ncig, thiab xaiv cov khoom raws li qhov xav tau;Los yog tswj qhov kub thiab txias ntawm cov khoom siv, cov tshuab, thiab cov ntsaws ruaj ruaj raws li kev ua haujlwm kub ntawm cov khoom siv.Xaiv cov khoom uas tuaj yeem tiv taus lawv qhov kub siab tshaj plaws.
- Ua haujlwm siab ntawm hydraulic seals
Kev ua haujlwm siab yog qhov ua haujlwm tseem ceeb ntawm cov tshuab hydraulic thiab pneumatic, uas tuaj yeem sib txawv ntawm 1-400MPa lossis ntau qhov loj dua.Lub siab tsis kam ntawm cov ntaub ntawv yuav tsum yoog raws li qhov xav tau ntawm kev ua haujlwm siab.
6. Puas yog qhov chaw ua haujlwm ntawm hydraulic seals paug Yog tias muaj plua plav paug hauv qhov chaw ua haujlwm, nws yuav ua rau cov khoom hnyav hnyav dua, thiab hnav tsis kam ntawm cov khoom yuav tsum tau txhim kho.Yog cov khoom ruaj khov lossis vibrating thaum ua haujlwm. tej yam kev mob, cov khoom yuav tsum muaj txaus elasticity los them rau qhov tsis txaus sealing kev sib cuag kev nyuaj siab tshwm sim los ntawm kev khiav tawm los ntawm kev co.
