CPP Main Propulsion System
Its optimal propeller diameter-totating speed combination helps to improve the propelleris propulsion efficiency,reduce diameter under the same propulsive force and enhance the tank capacity use rate.
The slanted blades and large blade area ratio help to reduce vibration and ensure better cavitation resistance.
Submerging these gears and bearing into the lubricant will help to improve lubricating and cooling effects and enhance sideways-acting reliability.
The use of optimal design for underwater mechanism allows compact structure and easy installation and maintenance.
Its good stern leak tightness is able to meet the increasing strict marine pollution prevention requirement.
Marine Tunnel Thruster
Application
Marine tunnel thruster is mainly used when the ship navigates in a narrow waterway, leans on a wharf, or turns a head, and the conventional rudder equipment is difficult or impossible to operate. It is also commonly used in ship operations in harsh environments.
Features
1.Type: controllable-pitch and fixed-pitch propeller type.
2.Installation type:vertical and horizontal installation.
3.High efficiency and endurance.
4.Driven force:electrical , hydraulic motor and diesel engine.
5.Suitable for various kinds of vessel such as transportation vessel, tugboat, ocean engineering vessel, ro-ro ship, cargo liner.
6.Underwater structure are convenient for maintenance and repairing.
7.Type:L transmission type and Z transmission type.
