Hydraulic systems yog ib qho tseem ceeb ntawm ntau qhov kev lag luam, suav nrog kev tsim kho, tsim khoom, thiab aerospace. Cov tshuab no tso siab rau lub zog ntawm cov kua dej los ua haujlwm xws li nqa, thawb, khoov, thiab txiav. Ib qho tseem ceeb ntawm cov tshuab no yog hydraulic foob.
Hydraulic Seals yog dab tsi?
Hydraulic seals yog cov mos mos, cov nplhaib uas tsis yog xim hlau siv los tiv thaiv cov kua dej los ntawm cov khoom siv hauv lub tog raj kheej hydraulic. Lawv feem ntau yog ua los ntawm cov ntaub ntawv xws li polyurethane, roj hmab, los yog Teflon. Qhov kev xaiv ntawm cov ntaub ntawv nyob ntawm seb yam xws li hom hydraulic kua siv, kev khiav hauj lwm kub ntawm lub system, thiab cov qib siab nws tuav.
Hom Hydraulic Seals
Hydraulic seals yog cov khoom tseem ceeb ntawm cov tshuab hydraulic thiab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov dej xau thiab tswj kev ua haujlwm zoo. Muaj ntau ntau hom hydraulic seals, txhua tus tsim los ua kom tau raws li cov kev cai tshwj xeeb thiab kev ua haujlwm. Kab lus no yuav ua tib zoo saib ntawm ntau hom hydraulic seals thiab lawv daim ntawv thov.
1. O-Ring: O-Ring yog hom hydraulic foob feem ntau. Lawv yog cov puag ncig hauv cov duab thiab ua los ntawm elastomers xws li nitrile, silicone, lossis carbon oxide. O-rings muaj ntau yam thiab tuaj yeem siv rau hauv ob qho tib si zoo li qub thiab dynamic daim ntaub ntawv.
2. Piston seals: Feem ntau yog siv nyob rau hauv hydraulic thooj voos kheej kheej los tiv thaiv cov kua los ntawm lub piston thiab lub tog raj kheej bore. Lawv feem ntau haum rau hauv qhov zawj hauv lub taub hau piston thiab muab lub foob dynamic uas tuaj yeem tiv taus kev kub ntxhov thiab kub hloov.
3. Qws foob: Kuj hu ua shaft foob, pas nrig foob yog siv los tiv thaiv cov dej xau ntawm tus pas nrig sab ntawm lub tog raj kheej hydraulic. Lawv muab lub foob zoo li qub ntawm tus pas nrig thiab lub tog raj kheej bore thiab muaj peev xwm tiv taus kev kub ntxhov, kev sib txhuam, thiab kub hloov pauv.
4. Plua plav pov thawj: Cov plua plav pov thawj tseem hu ua scraper seals thiab siv los tiv thaiv cov kab mob nkag mus rau hauv hydraulic system. Raws li cov pas nrig thim rov qab rau hauv lub tog raj kheej, lawv khawb av, plua plav, thiab ya raws tawm ntawm tus pas nrig nto, txuas lub neej ntawm lwm cov hydraulic seals.
5. Lub nplhaib hnav-tiv taus: kuj hu ua lub nplhaib coj los yog lub nplhaib bearing, nws coj lub piston thiab pas nrig hauv lub tog raj kheej hydraulic. Lawv muab qhov chaw txhawb nqa ntawm qhov txav mus los, txo kev sib txhuam thiab tiv thaiv kev sib cuag ntawm hlau-rau-hlau.
Kev tsim lub nplhaib hnav-tiv taus yog tsuas yog los tiv thaiv cov plua plav poob rau hauv lub piston pas nrig los ntawm kev coj mus rau hauv qhov kawg npog thiab lub tog raj kheej lub tog raj kheej nrog lub telescopic txav ntawm lub piston pas nrig, ua rau poob thiab hnav ntxov ntxov ntawm cov ntsaws ruaj ruaj thiab txhawb nqa rings. Thaum lub nplhaib hnav-tiv taus poob nws cov plua plav-pov thawj muaj nuj nqi, impurities yuav raug coj mus rau hauv lub tog raj kheej hydraulic, ua rau hnav mus rau sab hauv phab ntsa ntawm lub tog raj kheej hydraulic thiab sab nrauv phab ntsa ntawm hydraulic pas nrig.
6. Txhawb nqa lub nplhaib: Txhim kho qhov kev ua tau zoo ntawm lwm cov hydraulic seals los ntawm kev muab kev txhawb nqa ntxiv thiab kev tiv thaiv extrusion quab yuam. Lawv feem ntau yog ntsia rau ntawm ib lossis ob sab ntawm O-ring lossis lwm yam tseem ceeb.
7. Di ncauj seals: Feem ntau yog siv rau reciprocating seals. Piv nrog rau extrusion seals xws li O-rings, di ncauj ntsaws ruaj ruaj siv rau reciprocating seals muaj kev ua tau zoo tag nrho thiab kev pab lub neej ntev.
Lub sealing siab ntawm daim di ncauj foob nplhaib hloov nrog kev hloov ntawm qhov nruab nrab siab. Lub siab loj ua ntej yuav ua rau thaj chaw sib cuag ntawm lub nplhaib foob thiab lub sealing nto, ua rau muaj kev sib txhuam loj, thiab ua rau lub nplhaib foob puas. Thaum tsis tshua muaj siab Thaum nws ua rau muaj teeb meem hauv kev pib, lossis qhov tshwm sim creeping, lub nplhaib foob tuaj yeem ncab los ntawm daim di ncauj, thiab qhov deformation yuav them rau qhov me me ntawm hnav, ua kom cov nyhuv sealing thiab sealing lub neej; thaum O-ring muaj kev cuam tshuam ncaj qha rau nws qhov kev ua tau zoo raws li kev sib txhuam npoo qis.
Cov lus xaus
Hydraulic seals ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo ntawm cov tshuab hydraulic. Kev nkag siab txog cov yam ntxwv thiab kev ua haujlwm ntawm cov khoom sib txawv no tuaj yeem pab engineers xaiv lub foob rau lawv daim ntawv thov tshwj xeeb.
