Raws li offshore cua zog expansions ceev thoob ntiaj teb nyob rau hauv nruab nrab -2026, installation crews yog siv ntau txhiab kilometers ntawm siab -voltage subsea cables. Cov kab hluav taws xob hauv qab hiav txwv no xa hluav taws xob los ntawm cov cua turbines tawm sab nraud mus rau cov thawv sib txuas hauv qab hiav txwv thiab av- raws li daim phiaj. Txhawm rau lav kev xa hluav taws xob tsis muaj kev cuam tshuam nyob rau hauv dej hiav txwv huab cua, cov kws tsim khoom siv zog ua haujlwm hnyav -cov dej num elastomeric grommets thiab gaskets tsim rau kev pabcuam hauv hiav txwv tob.
Kev khiav dej num hauv qhov chaw sib sib zog nqus dej ua rau muaj kev ntxhov siab thiab tshuaj lom neeg ntawm cov khoom siv hluav taws xob nkag mus rau hauv cov ntsaws ruaj ruaj thiab hlws ris lub thawv gaskets. Ib qho me me tuaj yeem ua rau muaj kev puas tsuaj hluav taws xob hauv av thiab turbine downtime. Hauv qhov kev hloov tshiab no, peb tshuaj xyuas cov khoom elastomer thiab cov qauv tsim tsim nyog kom muaj sia nyob 25 xyoo nyob rau hauv dej hiav txwv.
1. Qhov Kev Sib Tw: Siab Hydrostatic Siab
Subsea fais fab cable nkag mus thiab cov thawv sib txuas yog feem ntau xa mus rau qhov tob li ntawm 30 txog 50 meters. Ntawm qhov tob no, lub hiav txwv ib puag ncig ua rau lub siab tsis tu ncua ntawm ** 3 txog 5 bar ** (kwv yees li 43 txog 72 psi).
Nyob rau hauv lub siab tsis tu ncua, dej molecules nrhiav ib qho micro- qhov sib txawv ntawm lub foob interface:
- High Compression Force:Watertight kev ncaj ncees yuav tsum tau gaskets nrog siab elastic rov qab. Lub foob yuav tsum ua kom muaj kev sib cuag siab dua li cov dej nyob ib puag ncig kom tiv thaiv kev nkag mus.
- Tsawg Compression Set:Tshaj li kaum xyoo ntawm kev pabcuam, lub foob yuav tsum tsis txhob so lossis deform mus tas li. Cov txheej txheem compression siab yuav ua rau lub foob xau hauv qhov kub hloov pauv.
2. Kev xaiv cov khoom siv: Tiv thaiv dej ntsev, UV, thiab Biofouling
Subsea cable seals ua haujlwm hauv thaj chaw txaws (xws li huab cua, UV, thiab nthwv dej) thiab thaj chaw tob tob (submerged hauv txias, ntsev- dej nplua nuj). Gaskets yuav tsum tiv thaiv corrosion thiab tshuaj tua kab mob:
- Marine-Qib EPDM:EPDM yog cov khoom siv zoo tshaj plaws rau cov ntaub ntawv hauv qab dej. Nws cov pob txha saturated polymer muab kev tiv thaiv zoo rau kev nqus dej, ntsev ions, ozone, thiab UV hluav taws xob, kom ntseeg tau tias cov khoom sib xyaw tsis o lossis qhuav -rot.
- Chloroprene (Neoprene):Neoprene nthuav tawm lub cev zoo heev, tsis muaj roj tsis kam, thiab nws tus kheej -extinguishing zog, ua rau nws tsim nyog rau cov kab tsheb thauj mus los thiab cov hlua tiv thaiv sab nraud.
- Anti-Biofouling Tsim:Smooth seal nto tiv thaiv cov kab mob hauv hiav txwv (xws li barnacles thiab algae) los ntawm kev thauj mus los, tiv thaiv daim di ncauj los ntawm kev puas tsuaj thaum lub sijhawm kuaj xyuas.
3. Dynamic Stress: Cable dabtsi yog khoov thiab strain nyem
Muaj zog dej hiav txwv tam sim no thiab nthwv dej surges ua rau subsea cables sway. Qhov twg cov cable hnyav dhau los ntawm cov phab ntsa ntawm cov hlau tsis sib xws ntawm lub hauv paus turbine lossis lub thawv sib txuas, kev ntxhov siab concentrates.
Txhawm rau tswj qhov dynamic load:
- Heavy-Lub luag haujlwm Roj Hmab Grommets:Thick -walled EPDM lossis Neoprene grommets raug ntsia ntawm qhov nkag. Cov grommets no tsim cov dej nruj nreem thiab ua raws li kev ua kom lub cev muaj zog, absorbing mechanical bending stresses.
- Kev tiv thaiv Sheath:Lub tes tsho elastomeric tiv thaiv cov hlau ntug ntawm lub phaj nkag los ntawm kev rub tawm thiab hlais lub tsho polyurethane sab nraud.
Marine Elastomer Xaiv Matrix
| Elastomer Chav Kawm | Kev ntsuas Hydrostatic | Ozone & UV Resistance | Daim ntawv thov tseem ceeb Marine |
