Cylinder liners in ships are critical engine components that form the inner wall of the cylinder. They provide a durable surface for piston movement and withstand high temperatures and pressures. These parts ensure efficient combustion and reduce wear in marine engines.
Cylinder Liner Ship Engine Parts Specifications:
Size: Typically ranges from 100mm to 1000mm in diameter, length varies based on engine design.
Grade: Common grades include ASTM A48 Class 30, ASTM A536, or proprietary engine manufacturer grades.
Viscosity: Not applicable directly to liner material, but lubricating oil viscosity (SAE 15W-40 or similar) is critical for operation.
Buoyancy: Negligible; liners are dense and non-buoyant due to metal construction.
Material: Typically made of cast iron (gray or ductile), alloyed cast iron, or steel with chrome plating for wear resistance.
Hardness: 180-250 HB for cast iron, up to 60 HRC for chrome-plated surfaces.
Surface Finish: Precision honed to 0.5-2.0 µm Ra for optimal piston ring sealing.
Thermal Conductivity: ~50 W/m·K for cast iron, aiding heat dissipation.
Pressure Resistance: Designed to withstand peak combustion pressures exceeding 200 bar.
Corrosion Resistance: Enhanced by coatings or alloying elements (e.g., chromium, nickel).
