Product Description

Design and Structure

• Unique Blade Design: The blades of our ice - breaking propellers are designed with a special shape. The blade thickness is optimized, usually with a thicker leading edge to enhance impact resistance. The angle of the blades is precisely calculated to generate maximum thrust while efficiently cutting through ice. For example, the blade pitch is adjusted according to different ice - breaking requirements, ensuring that the propeller can work effectively in various ice - thickness conditions.

• Robust Hub Structure: The hub of the propeller is designed to be short and thick. This structure can better withstand the torque and impact during ice - breaking operations. The connection between the hub and the blades is also strengthened, using advanced welding and fastening techniques to ensure that the propeller can operate stably under high - stress conditions.

Manufacturing Precision

Our manufacturing process adheres to strict international standards. For instance, in the casting process, we use advanced foundry techniques to ensure the internal quality of the propeller. The surface roughness of the propeller after processing can reach Ra0.8 - Ra1.6μm, reducing water resistance and improving the efficiency of the propeller. Each propeller undergoes a series of strict quality inspections, including dimensional accuracy inspection, where the allowable deviation of key dimensions is controlled within ±0.5mm.

Performance in Ice - Breaking

• Powerful Ice - Breaking Ability: Our stainless steel ice - breaking propellers can enable the ship to break through ice layers with a thickness of 0.8 - 1.5 meters at a speed of 1.5 - 2 knots. This performance is crucial for ships operating in polar regions or ice - covered waters, ensuring their normal navigation and mission execution.

• High - Efficiency Propulsion: Even in ice - laden waters, the propeller can maintain a high - efficiency propulsion performance. Compared with some traditional propellers, it can increase the ship's propulsion efficiency by 10% - 15%, reducing fuel consumption and operating costs.
• 

Customization Options

We offer a wide range of customization services. Whether it's adjusting the diameter of the propeller (ranging from 2 - 6 meters to meet different ship sizes), changing the number of blades (usually 3 - 5 blades, and the number can be customized according to specific needs), or adding special anti - corrosion coatings or wear - resistant treatments, we can tailor - make the ice - breaking propeller to perfectly match your ship's requirements.

 All Kinds Marine Copper Alloy Propeller For Ship

Controllable Pitch Propeller (CPP)
Our CPPs offer unparalleled maneuverability by adjusting blade pitch on - the - fly, enabling thrust changes without engine speed adjustments. This feature ensures high efficiency across speeds, cuts fuel consumption, and minimizes noise and vibration.

 

Available in various blade counts, weighing from hundreds of kilos to over 100 tonnes, with diameters of 0.5 - 12 meters, they suit tugboats, ferries, and offshore vessels. Design priorities include optimizing hydrodynamics, ensuring pitch - control reliability, and meeting classification society standards.

 

Backed by deep hydrodynamic knowledge and proven design tools from years of testing, our CPPs deliver top - tier performance and durability for enhanced vessel operations.
