Dengiz Propulyction Shartlari: 2205 VS . 2507 charchoq hayoti

 

Nima uchun dupleks 2205 tijorat tomirlarini ustunlik qiladi?
2205 yil davomida 450 MPAning kuchini ta'minlaydi. Super Dupleks 8- pren 35-sonli pren 35-sonli, 15- MV AG / AGCL) . .

 

Super Duplex 2507 oqlanganda oqlanadimi?
For naval vessels exceeding 25 knots where cavitation erosion dominates. 2507's 550 MPa strength allows smaller shaft diameters. PREN >42 . charchoqlardagi charchoq hayotidagi krevit korroziyasini oldini oladi .

 

Kavititsiyani yumshatish
Laser-hardened surfaces (600 HV) on leading edges. Optimized propeller NPSH >8M {1}. . . ultrasonik ta'sirni yaxshilaydi . ultrasonik ta'sirini yaxshilash 300% {{4} {{4} .

 

Stern naychani tanqid qiladimi?
