Cov khoom siv ntawm lub tog raj kheej roj foob nplhaib ntawm lub txiab nqa platform

Cov roj lub tog raj kheej foob lub nplhaib nyob rau hauv lub tshuab nqa nqa lub tshuab ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo thiab nyab xeeb ntawm cov tshuab hydraulic. Lub nplhaib foob no yog lub luag haujlwm los tiv thaiv cov dej ntws tawm ntawm cov dej hydraulic nyob rau hauv qhov siab, uas tso cai rau lub tshuab nqa nqa kom ruaj khov thiab ua nws cov haujlwm nqa nrog qhov tseeb. Cov khoom siv rau cov nplhaib foob no yog qhov tseem ceeb, vim nws yuav tsum tiv taus cov kev xav tau ntawm lub tshuab hydraulic, xws li kev kub siab, kub hloov pauv, kev sib txhuam, thiab raug rau ntau yam kua.
Cov khoom siv feem ntau siv hauv cov roj kheej kheej foob rings rau txiab nqa platforms muaj xws li nitrile roj hmab (NBR), polyurethane (PU), Viton, thiab PTFE (Polytetrafluoroethylene). Txhua yam khoom muaj qhov tshwj xeeb zoo, nyob ntawm kev ua haujlwm ntawm hydraulic system.
Nitrile roj hmab yog ib qho ntawm feem ntau siv cov ntaub ntawv vim nws zoo heev tiv taus roj, roj, thiab lwm yam hydraulic kua. Nws kuj muaj qhov zoo abrasion tsis kam thiab elasticity, ua rau nws haum rau nruab nrab siab thiab kub tej yam kev mob. NBR yog tus nqi-zoo thiab ua tau zoo nyob rau hauv ib puag ncig uas cov roj hydraulic raug tsis tu ncua.
Polyurethane cov ntsaws ruaj ruaj yog paub txog lawv cov kev tiv thaiv zoo heev rau hnav, tsim kua muag, thiab puas. Lawv feem ntau siv nyob rau hauv high-pressure hydraulic daim ntaub ntawv vim lawv durability thiab toughness. PU cov ntsaws ruaj ruaj tuaj yeem tiv taus ntau qhov kub thiab txias thiab muab lub peev xwm sealing zoo hauv cov ntawv thov dynamic, qhov twg muaj kev txav ntawm lub foob thiab lub tog raj kheej phab ntsa.
Viton yog fluorocarbon-raws li elastomer uas muab kev tiv thaiv tshwj xeeb rau cov cua sov, tshuaj lom neeg, thiab cov kua dej aggressive. Nws yog qhov tsim nyog rau kev siv qhov twg hydraulic system ua haujlwm nyob rau hauv qhov kub thiab txias hloov pauv los yog cuam tshuam rau cov khoom hnyav. Txawm hais tias kim dua NBR lossis PU, Viton cov ntsaws ruaj ruaj muab kev ua haujlwm ntev ntev hauv qhov xav tau ib puag ncig.
PTFE cov ntsaws ruaj ruaj yog cov resistant rau tshuaj thiab huab cua kub heev. Lawv feem ntau siv nyob rau hauv ib puag ncig uas lub tshuab hydraulic raug rau cov tshuaj hnyav, lossis thaum lub tshuab nqa nqa ua haujlwm nyob rau hauv qhov kub thiab txias heev. PTFE muaj kev sib txhuam tsis tshua muaj zog, ua rau nws zoo tagnrho rau kev txo qis hauv kev siv dynamic.
