Marine Hydraulic Tunnel Thruster


Application

A marine hydraulic tunnel thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It is a hydraulic motor-driven propeller that is mounted in a tunnel on the bow or stern of the vessel. The hydraulic motor provides power to the propeller, which generates a sideways force that can be used to turn the ship.

Hydraulic tunnel thrusters are commonly used in large vessels, as they can provide high levels of thrust and are able to handle heavier loads. They are also more reliable than electric thrusters, as they are not affected by power outages or other electrical issues. Hydraulic tunnel thrusters can be controlled using a joystick or a computerized system, which allows for precise and smooth maneuvering of the vessel. They can also be integrated with other ship systems, such as GPS and autopilot, to provide seamless operation.

Features
1. Skew and large area ratio blade leading to low vibration and better cavitation performance.

2. High strength and long life gears and bearing.

3. Optimal design or underwater mechanism,compact structure,easy installation.

4. Better seal to ensure tightness and meet requirements of strict marine pollution prevention.

5. We can design and manufacture the product according to client's drawing or sample.


We not only provide customers with high-quality products, but also provide complete system solutions and added services for specific customers. Therefore, There are  high competitiveness.

Maintenance advice

1. Regularly check whether there is leakage of hydraulic oil in the side thruster of the ship, regularly add tallow to the moving bearings and couplings, and replenish the hydraulic oil of the system in time.

2. Clean the dust in the ship's thruster control panel in time and check the working condition of the ACB.

If the ACB fails to close there are several reasons:

2.1. The control circuit has no electricity;

2.2. The main switch energy storage motor does not store energy normally;

2.3. There is no closing signal to the main switch closing coil;

2.4. The main switch under voltage coil has no electricity.
