Lub neej ntev ntawm hydraulic seals feem ntau cuam tshuam los ntawm ntau yam, suav nrog cov khoom siv, kev ua haujlwm siab, kev ua haujlwm kub, hom nruab nrab, kev teeb tsa zoo, thiab kev siv thiab kev saib xyuas.
Feem ntau, siab - hydraulic seals zoo tuaj yeem muaj lub neej ntev txij li ob peb txhiab mus rau kaum txhiab teev nyob rau hauv ib txwm ua haujlwm, nrog rau tus nqi tshwj xeeb sib txawv nyob ntawm daim ntawv thov thiab cov khoom siv.
Hais txog cov khoom siv, cov khoom siv feem ntau siv rau hydraulic seals muaj xws li roj hmab (xws li roj hmab nitrile thiab fluororubber), polyurethane, thiab polytetrafluoroethylene (PTFE). Lub neej ntev ntawm cov ntsaws ruaj ruaj ua los ntawm cov khoom sib txawv txawv heev. Piv txwv li, fluororubber ntsaws ruaj ruaj, vim lawv zoo heev - kub tsis kam thiab tshuaj corrosion kuj, muaj ib tug kuj ntev lifespan nyob rau hauv huab ua hauj lwm ib puag ncig; hos nitrile roj hmab foob, vim lawv zoo elasticity thiab hnav tsis kam, yog dav siv nyob rau hauv hydraulic systems, tab sis lawv lifespan yuav luv luv me ntsis ntawm fluororubber.
Kev khiav hauj lwm siab kuj yog ib qho tseem ceeb cuam tshuam rau lub neej ntawm hydraulic seals. Nyob rau hauv kev kub siab, qhov nce siab ntawm cov ntsaws ruaj ruaj tuaj yeem yooj yim ua rau cov khoom qaug zog thiab ua rau kev laus, yog li ua rau lawv lub neej luv. Yog li ntawd, thaum xaiv cov ntsaws ruaj ruaj, nws yog ib qho tsim nyog yuav tau xaiv cov khoom tsim nyog thiab cov qauv raws li qhov system ua haujlwm siab.
Kev khiav hauj lwm kub kuj tseem muaj feem cuam tshuam rau kev foob lub neej. Nyob rau hauv siab - qhov kub thiab txias, cov khoom siv lub nplhaib sealing tuaj yeem raug thermal aging, ua rau txo elasticity thiab tsis muaj zog sealing kev ua tau zoo. Piv txwv li, nyob rau hauv qis - qhov kub thiab txias ib puag ncig, cov khoom yuav nkig thiab yooj yim puas. Yog li ntawd, hydraulic systems ua hauj lwm nyob rau hauv huab cua kub tej yam kev mob yuav tsum tau sealing nplhaib nrog zoo heev kub kuj.
Hom kev tshaj tawm kuj yog ib qho tseem ceeb heev. Cov xov xwm sib txawv nthuav tawm qhov sib txawv ntawm corrosivity rau sealing nplhaib cov ntaub ntawv. Muaj zog corrosive xov xwm ceev cov txheej txheem kev laus ntawm lub nplhaib sealing, shortening nws cov kev pab cuam lub neej. Yog li ntawd, thaum xaiv sealing rings, hom xov xwm yuav tsum tau txiav txim siab tag nrho, thiab cov ntaub ntawv uas zoo corrosion kuj yuav tsum tau xaiv.
Tsis tas li ntawd, kev txhim kho zoo thiab kev saib xyuas zoo cuam tshuam rau lub neej ntawm kev sib khi rings. Txhim kho txoj kev txhim kho kom muaj kev sib cuag zoo ntawm lub nplhaib sealing thiab mating Cheebtsam, txo qhov kev pheej hmoo ntawm to. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua tuaj yeem tshawb xyuas tam sim thiab daws teeb meem xws li kev laus thiab hnav ntawm lub nplhaib sib khi, txuas ntxiv nws lub neej kev pab cuam.
Txhawm rau txuas ntxiv lub neej kev pab cuam ntawm hydraulic sealing rings, cov kev ntsuas hauv qab no tau pom zoo: 1) Siv lub nplhaib sealing ua los ntawm cov khoom zoo -; 2) Xaiv lub nplhaib sealing uas tsim nyog thiab cov lus qhia tshwj xeeb raws li kev ua haujlwm ntawm lub cev; 3) Xyuas kom tseeb installation txoj kev; 4) Tsis tu ncua tshuaj xyuas thiab tswj cov nplhaib sib khi, thiab hloov cov nplhaib uas muaj hnub nyoog lossis hnav.
