Controllable Pitch Propeller Bow Thruster
Controllable Pitch Propeller Bow Thruster：
CPP bow thruster can be driven by diesel engine or electric-motor. it can be installed vertically or horizontally. and design based on concept of reliability, durability, high efficiency and easy maintenance. The power can from 200 KW-2930KW,diameter from 1100mm-3000mm,thrust force from 16KN-462KN.
Tunnel thruster is that the ship is sailing in a narrow channel, port of call or sailing turn, instead the traditional rudder equipment difficult to operate or can’t operate, also used for ship operates in harsh environments. Such as: Water demining, laying cable.
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.
