Cov khoom lag luam
Marine kivpeller ncej sealing rings yog qhov tseem ceeb ntawm tus kiv cua ncej thiab lub siab tawv. Lawv txoj haujlwm tseem ceeb yog los tiv thaiv dej hiav txwv los ntawm kev nkag mus rau hauv Hull.
Qhov Zoo
Cov roj tseem tsis kam
Marine kivpeller ncej sealing rings yog ua los ntawm nitrile roj hmab (NBR), uas muaj cov roj hluav taws xob muaj zog tom qab kev nkag siab ntev yog tsawg dua 5%.
POTERE HEEV NTSIAB
Tus qauv qauv tuaj yeem ua kom elasticity nyob rau hauv thaj tsam ntawm -30}}}}}}} Cov cheeb tsam los ntawm cov cheeb tsam txias polar rau cov dej txias.
Dynamic sealing muaj peev xwm
Nyob rau hauv cov kev sib hloov siab ntawm cov kiv cua nqaj (siab kawg 15m / s linear kev co) thiab axial kev co kev sib tw siab.
Yig heev thiab muaj txiaj ntsig
Piv nrog cov tshuab sib xyaw ua ke, o-rings muaj ib tus qauv yooj yim, kev teeb tsa ceev, thiab ib chav tsev them nqi txo txog 70%.
Cov haujlwm thiab qhov tseem ceeb
1. Kev ua haujlwm yooj yim
Marine kivpeller ncej sealing rings yog thawj kab ntawm kev tiv thaiv rau lub kiv cua ncej sealing system thiab ua ntau dua li 80% ntawm cov haujlwm zoo li qub. Thaum tus kiv cua yog nyob ruaj ruaj, nws tso cai rau ntawm cov roj hmab ntawm roj hmab kom haum rau cov hlau nto kom nruj.
2. Dynamic Them Nyiaj Ua Haujlwm
Thaum lub nkoj caij nkoj, qhov kev co thiab eccentric thiab eccentric ncej tej zaum yuav ncav ± 0. 5 hli. Qhov hloov pauv tau ntawm O-Ring tuaj yeem nqus cov kev tshem tawm no kom tsis txhob raug foob.
3. Lub cev tiv thaiv tus nqi
Tiv thaiv kev txhim kho corrosion: Thaiv cov nkag ntawm cov ntsev ntsev thiab tiv thaiv cov kabmob.
Saib xyuas lubrication: Xyuas kom cov muaj peev xwm ntawm lubricating roj ntshahiav siab thiab nthuav tawm kev pabcuam lub neej ntawm lub thawv.
Ib puag ncig lub nkoj tuaj yeem txo qis {{{0} litres ntawm lubricating roj xau ib xyoos thiab zam kev ua qias tuaj.
