Marine Hydraulic Azimuth Thruster


Application

A marine hydraulic azimuth thruster is a type of propulsion system used in ships and boats that utilizes hydraulic power to rotate the thruster pod and provide thrust in any direction. The hydraulic system typically consists of a pump, motor, and piping that transfers hydraulic fluid to the thruster pod, which is mounted on a vertical axis and can rotate 360 degrees. The advantages of marine hydraulic azimuth thrusters include their high efficiency, reliability, and durability. They can provide high torque and thrust, making them suitable for larger vessels and heavy-duty applications. Additionally, hydraulic systems are often more resistant to corrosion and damage from harsh marine environments, compared to other types of propulsion systems.

Advantages

1. Higher propulsion efficiency,less noise and vibration.

2. Adopt high-strength gear and bearing to enhance seals and system’s reliability and longevity.

3. Clutch: built-in hydraulic or air pressure controlled clutch, external hydraulic clutch with reduction gear.

Features

1. Installation type:Transom installation,well installation or deck installation.

2. Steering gear for 360 degrees rotation.

3. Available in CP or FP propeller.

4. Products can be customized.

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.

Tunnel

Other brands

Easy to corrode, relatively poor quality.

WANXIANG
