Xoom Buoyancy Cable

Cov yam ntxwv ntawm cov khoom

Cov xov hlau xoom buoyancy muaj cov yam ntxwv zoo heev xws li tsis kam roj, tsis kam corrosion, tsis kam acid thiab alkali, tsis kam dej hiav txwv, tsis kam hydrolysis, tiv thaiv kev cuam tshuam, lub zog tensile siab, tiv thaiv ntses tom, kev nyab xeeb siab, txuag khoom siv, thiab txo nqi.

Daim ntawv thov

cov khoom sib xyaw

1. Qhov DC tsis kam ntawm tus neeg xyuas kab hlau tiav lawm (Chav Kawm R) (raws li GB3956 cov cai) yuav tsum xa mus rau Appendix A Rooj 2;

2. Txais yuav cov khoom siv rwb thaiv tsev thiab cov ntaub ntawv tiv thaiv dej tshwj xeeb uas xa tawm los ntawm txawv teb chaws;

3. Kev tsim tshwj xeeb thiab cov txheej txheem tsim khoom;

4. Thaum 20 ℃, qhov rwb thaiv tsev yuav tsum tsis pub tsawg dua 50M Ω / KM;

5. Lub cable tiav lawm yuav tsum tiv taus qhov kev sim AC voltage ntawm 50Hz, 3.5 kV, thiab 5 feeb yam tsis muaj kev tawg.

Cov ntaub ntawv khov kho uas siv rau cov xov hlau uas tsis muaj qhov hnyav yog polyurethane ua npuas ncauj, copolymer ua npuas ncauj thiab ua npuas ncauj sib xyaw. Lawv cov yam ntxwv thiab kev siv tau muab piv rau hauv qab no:

1. Ua npuas dej polyurethane

Cov yam ntxwv: Qhov ceev ntau yam 0.05-0.25g / cm ³, Qhov tob ua haujlwm yuav tsum tsis pub tshaj 200m;

Daim Ntawv Thov: Cov kav dej ntab, cov nkoj ntab, cov kav dej rwb thaiv tsev, cov hlua nqa hose, cov khoom siv ntab thaum muaj xwm txheej ceev luv luv;

2. Ua npuas ncauj copolymer

Cov yam ntxwv: Qhov ceev ntau ntawm 0.04-0.4g / cm ³, Qhov tob ua haujlwm yuav tsum tsis pub tshaj 600m lossis ntau dua;

Daim Ntawv Thov: ROV cov khoom ntab, umbilical floating, pore filling rau cov qauv loj hauv hiav txwv, pipeline rwb thaiv tsev, submersible tank floating khoom, thiab seabed buoys;

3. Cov khoom ua npuas dej sib xyaw

Cov yam ntxwv: cov yas ua npuas ncauj sib xyaw ua ke huv si muaj qhov ceev ntawm 0.46-0.65g / cm ³, Qhov tob ua haujlwm yog qhov tob tag nrho ntawm dej hiav txwv, thiab qhov ceev ntawm cov yas ua npuas ncauj sib xyaw ua ke yog 0.275-0.56g / cm ³, Qhov tob ua haujlwm hauv 4000m;

Daim Ntawv Thov: Siv dav hauv cov teb dej tob, xws li cov thaiv buoyancy rau cov khoom siv riser, cov thaiv buoyancy ROV tob hauv dej tob, cov ntab umbilical, thiab cov kav dej tob hauv dej tob.
