Marine cov ntaub ntawv txuas: Duplex 2205 vs . suplex 2507

 

Vim li cas cov qauv 2205 yog cov qauv rau cov nkoj lag luam?
2205 muaj Pren 35 thiab 450 mpa kom muaj zog ntawm ib nrab ntawm lub neej ntawm lub neej (}}}}}}}}

 

Thaum twg yog super duplex 2507 kev ncaj ncees?
For high-speed (>25 knot) naval vessels where cavitation erosion dominates. 2507's PREN >42 Tiv thaiv kev txiav txim siab corrosion hauv stern bearings . pa taws lub neej ntau dua li 10⁹ mais ntawm 100.

 

Cavitation puas tsuaj rau cov tswv yim?
Laser shock peening improves surface hardness (600 HV). Optimized propeller NPSH >8 {{{{{.} Kev Cuam Tshuam ZinDes ntawm Struts.} {.

 

Kev tsim kho lub raj tsim tseem ceeb?
Ntev / Lub Inch piv<4:1 prevents whirling vibration. Composite bearings with 0.3mm clearance. Triple-lip seals with freshwater lubrication. Continuous shaft grounding prevents stray current corrosion.
