Marine li qub yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov nkoj thiab cov chaw tawm sab nrauv, ua kom muaj kev tswj xyuas dej, kev tswj xyuas siab, thiab kev nyab xeeb. Txawm li cas los xij, vim qhov hnyav marine ib puag ncig, cov li qub no muaj kev cuam tshuam rau ntau yam teeb meem uas tuaj yeem cuam tshuam kev ua haujlwm thiab kev nyab xeeb. Kev nkag siab txog cov teeb meem no yog qhov tseem ceeb rau kev tiv thaiv kev saib xyuas thiab ua kom muaj kev ntseeg siab ntawm kev ua haujlwm.
1. Corrosion thiab khoom degradation
Teeb meem:
Kev raug dej ntsev thiab qhov kub thiab txias ua rau muaj kev xeb, ua rau cov khoom degradation thiab valve tsis ua hauj lwm. Corrosion tuaj yeem ua rau cov khoom siv tsis muaj zog, ua rau cov xau thiab txo lawv txoj sia.
Kev daws:
- Siv cov khoom siv corrosion-resistant xws li stainless hlau, bronze, lossis tshwj xeeb coated alloys.
- Siv cov coatings tiv thaiv thiab tsis tu ncua tshawb xyuas cov cim qhia ntxov ntawm corrosion.
- Siv cov txheej txheem tiv thaiv cathodic kom txo tau cov corrosion hauv cov dej hauv dej.
2. Cov dej ntws thiab foob tsis tiav
Teeb meem:
Nyob rau tib lub sijhawm, cov ntsaws ruaj ruaj thiab gaskets tuaj yeem hnav, ua rau xau. Kev kub siab, kev co, thiab kev teeb tsa tsis raug ua rau qhov teeb meem no. Cov dej xau tuaj yeem ua rau poob dej, muaj kev phom sij ib puag ncig, thiab kev ua haujlwm tsis zoo.
Kev daws:
- Tsis tu ncua tshuaj xyuas cov ntsaws ruaj ruaj thiab hloov lawv ua ib feem ntawm kev saib xyuas niaj hnub.
- Siv cov khoom zoo, qib marine-qib ntsaws ruaj ruaj thiab gaskets.
- Xyuas kom cov li qub tau teeb tsa kom raug thiab nruj rau cov lus pom zoo.
3. Thaiv thiab txhaws
Teeb meem:
Marine li qub tuaj yeem cuam tshuam nrog cov khib nyiab, cov khib nyiab, thiab kev loj hlob hauv hiav txwv, txwv cov dej ntws thiab txo cov kev ua haujlwm. Qhov no tshwj xeeb tshaj yog nyob rau hauv seawater intake systems.
Kev daws:
- Txhim kho cov lim dej thiab lim dej ntws ntawm cov qhov tseem ceeb rau cov khib nyiab.
- Ua lub sijhawm ntuav ntawm lub valve thiab cov kav dej.
- Siv cov tshuaj ntxuav tus kheej hauv cov chaw uas muaj kab mob hnyav.
4. Mechanical Hnav thiab tsim kua muag
Teeb meem:
Kev ua haujlwm tsis tu ncua, kev kub siab, thiab dej turbulence ua rau txhua yam hnav ntawm lub valve sab hauv, ua rau txo qis kev ua haujlwm thiab muaj peev xwm ua tsis tiav. Cheebtsam xws li valve stems, rooj zaum, thiab discs yog tshwj xeeb yog yooj yim.
Kev daws:
- Ua raws li lub sijhawm saib xyuas niaj hnub los tshuaj xyuas thiab hloov cov khoom hnav.
- Siv cov khoom hnav-tiv taus thiab tawv-fab coatings rau cov khoom tseem ceeb.
- Lubricate txav qhov chaw tsis tu ncua kom txo kev sib txhuam thiab hnav.
5. Kev ua haujlwm tsis zoo ntawm Valve
Teeb meem:
Tib neeg kev ua yuam kev, xws li qhov tsis raug valve qhov chaw lossis kev nruj dhau, tuaj yeem ua rau lub valve puas, ua rau muaj teeb meem kev ua haujlwm. Misalignment kuj tuaj yeem tshwm sim thaum lub sijhawm teeb tsa.
Kev daws:
- Qhia cov neeg ua haujlwm ntawm kev ua haujlwm valve kom raug thiab tuav cov txheej txheem.
- Siv automated los yog remotely ua li qub kom txo tau phau ntawv yuam kev.
- Ua kev ntsuam xyuas tom qab kev teeb tsa kom ntseeg tau tias kev sib raug zoo thiab kev ua haujlwm zoo.
6. Kev kub siab thiab dej rauj
Teeb meem:
Kev hloov siab sai sai, lub npe hu ua dej rauj, tuaj yeem ua rau cov dej hiav txwv puas tsuaj, ua rau tawg, deformation, lossis kev sib tsoo. Qhov no tuaj yeem tshwm sim thaum cov valve raug kaw sai dhau los yog cov twj tso kua mis kaw dheev.
Kev daws:
- Nruab surge arrestors thiab qeeb-kaw li qub los tswj kev hloov siab.
- Siv cov huab cua los yog cov dampeners kom nqus tau sai sai.
- Maj mam qhib thiab kaw li qub kom tiv thaiv kev hloov siab ceev.
7. Valve Jamming lossis Sticking
Teeb meem:
Marine li qub yuav jam los yog lo vim xeb, khib nyiab, los yog tsis muaj lubrication. Qhov no tuaj yeem tiv thaiv lub valve los ntawm kev qhib lossis kaw tag nrho, ua rau muaj kev phom sij rau kev nyab xeeb.
Kev daws:
- Tsis tu ncua lubricate valve Cheebtsam kom tsis txhob ua raws.
- Kev tawm dag zog li qub ib ntus kom ntseeg tau tias lawv nyob twj ywm.
- Siv cov tshuaj tiv thaiv fouling los tiv thaiv cov khib nyiab thiab xeb.
8. Calibration Drift
Teeb meem:
Sij hawm dhau mus, li qub uas xav tau kev ntsuas qhov tseeb, xws li kev tswj xyuas siab lossis kev nyab xeeb li qub, tuaj yeem tawm ntawm qhov tshwj xeeb, cuam tshuam kev ua haujlwm.
Kev daws:
- Teem caij calibration checks thiab recalibrate li qub raws li xav tau.
- Siv high-precision li qub nrog tsawg drift rau kev siv tseem ceeb.
- Sau cov ntaub ntawv calibration los taug qab cov kev ua tau zoo thiab txheeb xyuas cov teeb meem tshwm sim thaum ntxov.
