Xaiv cov khoom siv raug rau koj cov ntsaws ruaj ruaj hydraulic yog ib qho tseem ceeb tshaj plaws hauv kev tiv thaiv kev xau thiab ua kom lub neej ntev. Lub foob ua los ntawm cov khoom tsis raug tuaj yeem ua tsis tiav hauv cov xuab moos vim muaj tshuaj lom neeg tsis sib xws, kev puas tsuaj los ntawm tshav kub, lossis extrusion.
Phau ntawv qhia no sib piv cov khoom siv hydraulic feem ntau -NBR, FKM, PU, PTFE, thiab EPDM-los pab koj txiav txim siab paub txog koj qhov kev thov tshwj xeeb.
3 Yam Tseem Ceeb uas yuav tsum xav txog ua ntej xaiv
- 1. Qhov kub thiab txias:Puas yog koj lub cev ua haujlwm hauv qhov txias txias lossis kub kub? Kev khiav hauj lwm sab nraud ntawm cov khoom siv ntau yam ua rau hardening (txias) lossis degradation (kub).
- 2. Kua Compatibility:Lub foob yuav tsum sib haum nrog koj cov kua dej hydraulic (mineral oil, dej-glycol, hluavtaws, thiab lwm yam) los tiv thaiv o los yog yaj.
- 3. System Siab:Siab - cov tshuab siab xav tau cov ntaub ntawv nyuaj dua, muaj zog dua li Polyurethane lossis PTFE los tiv thaiv qhov sib txawv ntawm extrusion.
Cov Khoom Siv Hydraulic Seal Piav Qhia
1. Nitrile Roj Hmab (NBR / Buna-N)
Standard Industry Workhorse.NBR yog cov khoom siv dav tshaj plaws rau kev siv dav dav -lub hom phiaj hydraulic seals vim nws zoo heev tiv thaiv cov roj ntxhia thiab tus nqi qis.

Cov lus nug nquag
Q: Kuv puas tuaj yeem siv FKM cov ntsaws ruaj ruaj tsis yog NBR?
A: Yog lawm, FKM feem ntau yog qhov kev txhim kho zoo tshaj plaws rau NBR, muab cov cua sov zoo dua thiab tshuaj tiv thaiv. Txawm li cas los xij, nws kim dua thiab muaj qhov tsis zoo qis dua - qhov kub thiab txias.
Q: Vim li cas kuv lub foob tawg?
A: Qhov no feem ntau yog vim muaj tshuaj lom neeg tsis sib haum. Piv txwv li, siv EPDM cov ntsaws ruaj ruaj nrog cov roj ntxhia, lossis siv tus qauv NBR nrog phosphate ester kua.
