Feem ntau Siv Cov Khoom Rau Kev Sib Thooj Zog Rau Hydraulic
Ntau yam ntaub ntim khoom siv sib xyaw rau ntau lub cim rau ntawm lawv tus yam ntxwv.
Sealing cov ntaub ntawv siv los siv rau hauv cov khoom lag luam faiv muag feem ntau yog tsim los ntawm hluavtaws thiab hluavtaws hluavtaws. Feem ntau siv cov ntaub ntim khoom siv yog polytetrafluoroethylene (PTFE), polyurethane (PU), roj hmab (NBR), thiab roj hmab (VMQ). Thiab fluororubber (FKM), thiab lwm yam, yog tag nrho cov ntaub ntawv nrog cov khoom sib khi zoo, uas tuaj yeem muab kev ua si tag nrho rau lawv tus cwj pwm zoo.
1. Polytetrafluoroethylene = "PTFE"
Nta:
- Zoo tshuaj ruaj khov,
- Zoo tshav kub ua haujlwm,
- Tsawg thiab kub kub tsis kam,
- Yuav luag txhua daim ntawv tshaj tawm, xws li roj, dej, nkev, tshuaj, thiab lwm yam.
- Kev kho siab zog,
- Kev kub siab ua hauj,
- Zoo hnav ua haujlwm.
- Tsis tshua muaj kev sib txhuam thiab kev nplua tus kheej lub cev
Ua haujlwm kub : -30 ° C ~ + 200 ° C (xaiv O-nplhaib ntawm cov khoom tsim raws li kev ua haujlwm)
Siv : nplua ib ncig, hnav rings thiab qhia rings (strips) thiab lwm yam. Nws yog dav siv nyob rau hauv tag nrho cov lag luam xws li engineering tshuab thiab lub teeb industrial machinery.
Feem ntau, muaj PTFE paug ntau dua li ib yam khoom hydraulic ntau dua PTFE ntshiab. Feem ntau siv cov pob khoom siv yog tooj liab, iav fiber ntau thiab carbon fiber ; cov fillers no tuaj yeem txo qhov coefficient ntawm thermal expansion, ua kom muaj cua sov hloov mus, nce hnyav ua haujlwm thiab txhim kho neeg ua haujlwm kev ua haujlwm. PTFE nws tus kheej tsis yoog raws thiab feem ntau siv ua nrog rubber elastomers.
2. Polyurethane = "PU"
Nta:
- Cov khoom siv zoo heev,
- Me me yuam kev deformation,
- Tensile muaj zog,
- Zoo coj zoo;
Ua haujlwm kub : -30 ° C ~ + 100 ° C;
Kev Siv : Reciprocating seals hauv hydraulic systems, xws li Y-rings, U-rings, lwm yam.
3. NBR roj hmab = "NBR"
Nta :
- Cov roj av zoo,
- Tau tshaj cov kua roj ntau hom thiab roj, tab sis tsis haum rau phosphate ester series hydraulic cov roj thiab cov iav roj uas muaj roj ntxiv.
Ua haujlwm kub : -40 ° C ~ + 120 ° C
Siv : Nws yog siv los tsim O-rings, roj ntsaws ruaj ruaj, thiab lwm yam. Nws yog haum rau kev hydraulic roj.
4. Fluororubber = "FKM los yog FPM"
Nta : kev kub ntawm lub cev, acid thiab alkali tsis kam thiab lwm yam chemicals, roj tsis ua hauj lwm (xws li phosphate ester series lubricants), yuav luag txhua lub mineral-based thiab hluavtaws based hydraulic roj, tab sis nyob rau hauv cov ntaub ntawv ntawm lub zog, dej kub los yog tsawg kub, muaj qee cov kev txwv Tias yog hais, nws qhov kev kub tsis tshua muaj kev txwv.
Ua haujlwm kub : -20 ° C ~ + 200 ° C
Ua hauj lwm tawm Haum rau txhua lub roj lubrication thiab hydraulic roj.
5. Silicone rubber = "PMQ los yog VMQ"
Nta :
- Cov cua kub zoo, ua kom txias, me me compression, tab sis tsis tshua muaj neeg kho tshuab, tsuas tsim rau zoo li qub sealing.
6. Nylon = "PA"
Cov ntsiab lus tseem ceeb : cov roj av tsis zoo, kev ua haujlwm zoo, kev sib zog ua kom muaj zog, muaj zog ua haujlwm, tab sis tsis ruaj ntseg.
Ua haujlwm kub : -40 ° C ~ + 120 ° C
Kev Siv : Nws yog siv los tsim kev qhia lub nplhaib, qhia lub tes tsho, nyiaj ntiv nplhaib, lub nplhaib siab, tuav ntiv nplhaib thiab ntxiv rau.
Guangzhou Jinbond Hydraulic Sealing Technology Co., Ltd. muab cov hydraulic ntsaws ruaj ruaj (pneumatic seals), inch nkag los ntawm Φ6mm rau Φ2000mm, khoom nta nrog kev sib txhuam tsis tshua muaj kev sib txhuam, dav kub thiab ntev lub neej. Email peb rau cov lus nug: sales@jinbondseal.com
