Tunnel thruster:

Marine electric Tunnel Thruster: 

The tunnel thruster is widely used in various kinds of ships and can be driven by diesel engine or electric-motor. According to the thruster type it can be divided into two types - fixed pitch propeller and controllable pitch propeller, it can be installed vertically or horizontally. and design based on concept of reliability, durability, high efficiency and easy maintenance.

Feature:
1.The propeller’s diameter-speed combination is optimized so that propulsion efficiency is improved, reduce diameter while keep the same thrust force.
2.Adopt skew and large area ratio blade leading to low vibration and better cavitation performance.
3.High strength and long life gears and bearings is used and good lubrication and cooling is realized to improve whole machine’s reliability.
4.The use of optimal design for underwater mechanism allows compact structure and easy installation and maintenance.
5.Used better stern seal to ensure tightness and meet requirements of increasingly strict marine pollution prevention.
