Hauv hydraulic systems,roj hmab gasketsraug kev kub ntxhov, kub hloov pauv, thiab raug rau ntau yam hydraulic roj thiab cov kua dej tshuaj. Kev xaiv cov khoom siv tsis raug tuaj yeem ua tsis tau tsuas yog luv luv lub gasket lub neej kev pab tab sis kuj cuam tshuam rau tag nrho cov system kev ua tau zoo thiab kev nyab xeeb. Phau ntawv qhia no yuav muab cov ncauj lus kom ntxaws txog kev xaiv cov khoom siv rau hydraulic roj hmab gaskets.
Vim li cas xaiv cov khoom tseem ceeb hauv kev siv Hydraulic
Hydraulic systems xav tau siab -kev ua tau zoo sealing daws. Cov khoom siv gasket zoo kom ntseeg tau tias:
• Tiv thaiv cov kua dej tawm hauv qhov siab -siab
• Tuav lub siab ruaj khov thaum lub sijhawm ua haujlwm
• Lub neej ntev kev pab cuam ntawm ob lub gaskets thiab khoom siv
• Txo lub sij hawm poob thiab kev tu ntau zaus
Common Rubber Gasket Cov Khoom Siv rau Hydraulic Systems

Yuav Ua Li Cas Xaiv Cov Khoom Siv Zoo rau Koj Lub Tshuab Hydraulic
Xaiv cov khoom siv roj hmab zoo yog nyob ntawm qhov kev ua haujlwm tiag tiag ntawm koj qhov system hydraulic. Cov hauv qab no tseem ceeb tshwj xeeb:
Ua haujlwm kub
Nkag siab txog qhov system qhov siab tshaj plaws thiab qhov ntsuas kub tsawg kawg nkaus kom ntseeg tau tias cov khoom tuav elasticity thiab sealing kev ua tau zoo thoob plaws tag nrho.
01
Ua Haujlwm Siab
Xaiv cov ntaub ntawv raws li qhov system lub siab. Siab- cov tshuab siab siab yuav tsum muaj zog, hnav- cov ntaub ntawv tiv taus xws li HNBR, thaum qis - cov tshuab siab tuaj yeem siv EPDM lossis NBR.
02
Hom Hydraulic Fluid
Cov ntaub ntawv sib txawv yog sib xws nrog cov kua sib txawv, xws li cov roj ntxhia, dej -raws li hydraulic kua, lossis roj hluavtaws. Nws yog ib qho tseem ceeb los xaiv lub gasket uas yuav tsis degrade, o, los yog ua tsis tiav vim cov kua.
03
Daim ntawv thov Static lossis Dynamic Sealing Applications
Static seals tsuas yog xav tau cov ntaub ntawv uas muab kev ruaj ntseg siab sealing. Dynamic seals, xws li cov pistons los yog rotating shafts, xav tau zoo hnav tsis kam thiab compression teeb tsa kom ntseeg tau ntev -lub sij hawm.
04
Environmental Factors
Xav txog seb lub kaw lus puas raug UV, cov av noo siab, tshuaj lom neeg, lossis lwm yam mob hnyav, thiab xaiv cov khoom siv nrog huab cua txaus thiab tshuaj tiv thaiv kom muaj kev ua haujlwm ntev -.
