Marine Diesel Engine Tunnel Thruster



Application

A marine diesel engine tunnel thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It consists of a diesel engine that drives a propeller located in a tunnel on the bow or stern of the vessel. Diesel engine tunnel thrusters are commonly used in larger vessels, such as cargo ships and oil tankers, where high levels of thrust are required to maneuver in and out of ports and harbors. They are capable of generating high levels of power and can provide excellent maneuverability in challenging marine environments.

Propeller

Cast iron

Easy to corrode, easy to rust

Stainless steel

Good corrosion resistance, high hardness

Manganese Bronze (Cu1)

It has high strength, hardness and good plasticity, can well withstand pressure processing in hot and cold states, has good corrosion resistance, and has high thermal strength.

Brass

Dezincification is easy to occur in seawater, resulting in cavitation corrosion and affecting navigation safety.

Ni-Mn Bronze (Cu2)

High strength, good hardness, good wear resistance, good elasticity, no spark, corrosion resistance, non-magnetic, excellent cold working performance, excellent electroplating and welding performance.

Ni-Al-Bronze (Cu3)

Excellent comprehensive mechanical properties, resistance to stress corrosion cracking, corrosion fatigue resistance, cavitation corrosion resistance, erosion resistance, marine biofouling resistance. After heat treatment, it can reach the level of duplex stainless steel. Compared with brass, the corrosion resistance is three times that of brass, and the wear resistance is twice that of brass.
