Kev xaiv ntawmCov khoom siv foobs:
Feem ntau siv cov ntaub ntawv foobntawm peb lub tuam txhab yog Polyurethane, Nitrile roj hmab, Fluororubber, PTFE, thiab lwm yam, thiab ntau yam ntaub ntawv muaj cov yam ntxwv sib txawv, raws li nram no:
(1) Cov khoom siv polyurethane muaj qhov hnav tsis kam thiab me me compression deformation tus nqi, thiab feem ntau yog siv nyob rau hauv dynamic sealing zaus.Nws tuaj yeem tiv taus qhov ua haujlwm kub ntawm -35-100 ℃, thiab yog tsim rau roj av hydraulic roj.Tsuas yog cov khoom siv txawv teb chaws, nws muaj qhov tsis zoo hydrolysis tsis zoo thiab tsis tuaj yeem siv rau cov roj hydraulic, xws li dej glycol.
(2) Cov khoom siv roj hmab Nitrile muaj kev hnav tsis zoo, thiab feem ntau yog siv rau hauv txoj haujlwm sib khi zoo li qub, lossis ua ke nrog lwm cov ntaub ntawv hnav-tiv taus los tsim cov nplhaib sib khi, xws li Glyd rings thiab Kauj Ruam seals.Nws tuaj yeem tiv taus kev ua haujlwm kub ntawm -10-80 ℃, thiab muaj kev sib raug zoo nrog ntau yam roj hydraulic tshwj tsis yog phosphate ester.
(3) Cov khoom siv fluororubber muaj kev hnav tsis zoo thiab muaj peev xwm tiv thaiv extrusion.Nws feem ntau yog siv nyob rau hauv qhov zoo li qub sealing txoj hauj lwm, los yog ua ke nrog rau lwm yam hnav-resistant ntaub ntawv los tsim ib tug dynamic sealing nplhaib.Thaum nws yog siv rau dynamic sealing ib leeg, ib tug retainer nplhaib yuav tsum tau ntxiv los tiv thaiv extrusion tawm.Nws tuaj yeem tiv taus kev ua haujlwm kub ntawm -20-160 ° C, thiab tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias ntawm 200 ° C rau lub sijhawm luv luv, thiab muaj kev sib raug zoo nrog ntau yam roj hydraulic.
(4) PTFE cov khoom muaj kev hnav zoo thiab muaj peev xwm tiv thaiv extrusion.Nws feem ntau yog siv ua ke nrog cov khoom siv roj hmab los ua ib lub foob dynamic.Txawm li cas los xij, vim nws qhov loj compression deformation tus nqi, nws yuav ua rau kom loj thaum siv ntawm qhov tsis tshua muaj siab.Feem ntau nws yog siv nyob rau hauv ib puag ncig kub siab tshaj 25MPa.Nws tuaj yeem tiv taus qhov ua haujlwm kub ntawm -40-135 ℃, thiab muaj kev sib raug zoo nrog ntau yam roj hydraulic.
