Hydraulic sealing ntawm cua turbines rau tub rog thiab pej xeem siv
Hydraulic seals ua lub luag haujlwm tseem ceeb hauv kev ua tub rog thiab pej xeem cua turbines los tiv thaiv cov kua xau hauv hydraulic system thiab cov kab mob sab nraud los ntawm kev nkag mus rau hauv lub cev. Cov hauv qab no yog cov ncauj lus kom ntxaws txog hydraulic seals, suav nrog cov khoom siv kho tshuab, cov khoom siv lub cev, cov khoom siv tshuaj thiab cov khoom ua haujlwm.
Mechanical cwj pwm
Compressibility: Hydraulic seals yuav tsum muaj compressibility zoo, muaj peev xwm hloov mus rau kev hloov siab hauv hydraulic system, thiab sau lub foob qhov sib txawv kom nruj kom tsis txhob muaj kua xau.
Elasticity thiab rov qab: Hydraulic ntsaws ruaj ruaj yuav tsum muaj elasticity zoo thiab rov qab los xyuas kom meej tias lub foob tuaj yeem tuav nruj nruj thaum lub sijhawm ua haujlwm thiab yuav tsis raug deformed mus tas li los yog xoob.
Lub cev muaj zog
Sealing kev ua tau zoo: Hydraulic seals yuav tsum muaj kev sib khi zoo heev thiab tuaj yeem tiv thaiv kom tsis txhob muaj kua lossis roj. Lawv yuav tsum muaj peev xwm tiv taus kev ua hauj lwm nyob rau hauv kev kub siab, kub thiab kub ceev tej yam kev mob los xyuas kom meej cov kev ua hauj lwm ntawm lub cev.
Hnav thiab sib tsoo kev ua tau zoo: Hydraulic seals yuav tsum muaj kev hnav zoo thiab kev sib tsoo ua haujlwm kom txo tau kev sib txhuam thiab hnav thiab txuas ntxiv lub neej kev pabcuam ntawm lub foob.
Cov khoom siv tshuaj
Roj tsis kam: Hydraulic seals yuav tsum muaj roj zoo, ua tau zoo nrog cov roj hydraulic hauv hydraulic system, thiab yuav tsis nthuav, tawv los yog yaj vim kev sib cuag nrog roj.
Tshuaj tiv thaiv: Hydraulic seals yuav tsum muaj tshuaj-resistant thiab muaj peev xwm tiv taus corrosion thiab yaig los ntawm qee cov khoom siv tshuaj thiab cov roj nplua nyeem.
Kev ua tau zoo
Processability: Hydraulic seals yuav tsum yooj yim rau txheej txheem thiab tsim kom tau raws li qhov xav tau ntawm cov duab sib txawv thiab ntau thiab tsawg. Cov txheej txheem ua haujlwm feem ntau suav nrog kev txhaj tshuaj molding, extrusion, thiab nias.
Dimensional stability: Hydraulic seals yuav tsum muaj qhov ruaj khov kom ntseeg tau tias qhov ntev ntawm lub foob nyob ruaj khov nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias yam tsis muaj kev nthuav dav lossis kev cog lus.
Raws li cov ntsiab lus, hydraulic seals ua lub luag haujlwm tseem ceeb hauv kev ua tub rog thiab pej xeem cua turbines. Cov kev xav tau rau nws cov khoom siv kho tshuab, cov khoom siv lub cev, cov khoom siv tshuaj lom neeg thiab cov khoom ua haujlwm yog txhua yam los xyuas kom meej qhov kev ntseeg tau, sealing thiab durability ntawm hydraulic system. Cov kev xaiv tshwj xeeb yuav tsum raug soj ntsuam thiab xaiv raws li cov kev xav tau ntawm daim ntawv thov, kev ua haujlwm, thiab hydraulic system yuav tsum tau ua.
Roj hmab foob siv nyob rau hauv cua turbine hydraulic systems ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov kua dej tawm thiab cov kab mob sab nraud los ntawm kev nkag mus rau hauv lub cev.
- Kev xaiv cov khoom siv: Cua turbine hydraulic seals feem ntau yog ua los ntawm cov khoom siv roj hmab. Cov khoom siv roj hmab feem ntau muaj xws li nitrile roj hmab (NBR), fluorine roj hmab (FKM), butyl roj hmab (BR), thiab lwm yam. Xaiv cov khoom siv roj hmab uas tsim nyog nyob ntawm qhov chaw ua haujlwm, qhov kub thiab txias, qhov xav tau siab thiab qhov nruab nrab ntawm cov kua nruab nrab.
- Daim ntawv foob: Cov ntaub ntawv roj hmab feem ntau muaj xws li O-rings, U-rings, roj ntsaws ruaj ruaj thiab piston seals, thiab lwm yam. O-ring yog hom sealing tshaj plaws. Nws yog ua los ntawm cov roj hmab annular thiab yog siv los sau qhov sib txawv sealing kom ua tiav zoo li qub lossis dynamic sealing. Roj ntsaws ruaj ruaj yog siv los ua cov ntsaws ruaj ruaj los tiv thaiv cov kua dej los ntawm cov rotating ncej. Piston ntsaws ruaj ruaj yog siv los kaw lub piston hauv lub tog raj kheej hydraulic kom ntseeg tau tias cov kua sib cais ntawm ob sab ntawm lub piston.
