Marine Electric Tunnel Thruster
Application
A marine electric tunnel thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It is an electric motor-driven propeller that is mounted in a tunnel on the bow or stern of the vessel. The electric motor provides power to the propeller, which generates a sideways force that can be used to turn the ship. Electric tunnel thrusters are becoming increasingly popular in modern vessels due to their efficiency, reliability, and ease of maintenance. They are also more environmentally friendly than traditional diesel-powered thrusters, as they produce fewer emissions and have lower fuel consumption.
Features
1. Drive force: electric motor.
2. Installation type: installed vertically or horizontally.
3. Provide thrust to the vessel to move sideways.
4. Propeller dia: 250 mm to 3300 mm.
5. Input power: 20 KW to 3500 KW.
6. We can design and manufacture the product according to client's drawing or sample.

Tunnel Thruster of Precautions for Installation on Board (for reference only)

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 Undervoltage coil has no electricity.
