Marine Fixed Pitch Propeller
Fixed Pitch Propeller (FPP) for marine use refers to a propeller whose pitch (i.e. the distance it propels the ship per revolution) is fixed and cannot be adjusted.
This type of propeller is usually made of high-strength and corrosion-resistant materials such as bronze, stainless steel, or nickel aluminum bronze alloy, and is widely used in various types of ships, including cargo ships, oil tankers, container ships, ferries, etc.
Overview
A marine fixed pitch propeller refers to a propeller in which the hub and blades are cast together. Each ship's hull has its own characteristics, and in order to achieve the highest possible overall efficiency, the propeller must be perfectly matched with the engine and hull. HI-SEA MARINE can customize marine fixed pitch propellers with various blade quantities and size requirements according to customer needs.
Application of marine fixed pitch propellers
Fixed pitch propellers are usually installed on ocean going vessels, such as:
Container ship
tanker
Bulk cargo ship
Dry cargo ship
cruise liner
......
Characteristics of fixed pitch propellers
Simple structure: Due to the lack of complex mechanisms for adjusting pitch, the structure is simpler and the manufacturing and maintenance costs are lower.
High efficiency: High efficiency under design conditions, especially suitable for ships with relatively stable sailing speed and operating conditions.
Strong durability: The mechanical structure of fixed pitch propellers is simple, with a low failure rate and strong durability.
Easy to maintenance and repair
The design of fixed pitch propellers for ships usually needs to consider the following key factors:
Pitch: Select the appropriate pitch based on the design speed and engine power of the vessel.
Number and shape of blades: Design appropriate number and shape of blades based on the characteristics of the ship and navigation requirements to ensure optimal propulsion efficiency and reduce noise and vibration.
Material selection: Choose high-strength and corrosion-resistant materials to ensure the service life and reliability of the propeller. For example: Manganese bronze (Cu1), Nickel manganese bronze (Cu2), Nickel aluminum bronze (Cu3), Manganese aluminum bronze (Cu4), Stainless Steel, etc.
