Marine Rudder Propeller
Marine Rudder Propeller:
The rudder propeller can be mechanically or hydraulically raised or lowered in vertical direction by means of a depth adjustment facility .The serves to ensure maximum propeller thrust at all vessel draughts by maintaining the correct propeller immersion.
For maintenance purposes, the rudder thruster can be pivoted out of the water to the rear hydraulically or mechanically by hand.
Characteristics:
1.The propeller is combined design with nozzle. Plus its suitable large diameter and low rotating speed design, the propulsive force and efficiency are hence improved;
2.the shape of rudder-rod and its distance to propeller are optimized so as to further improve efficiency and reduce vibration and steering moment;
3.The reliability and service life are increased significantly by using high strength gears, high rotating speed bearings and well-designed leak tightness and oil way;
4.The steering mode can be hydraulic motor-driven or electrical motor-driven.Drive power from 20KW- 4500KW
5.According to the propeller, it can be divided into FPP and CPP type, open or with nozzle. Propeller diameter from 500 mm-4200 mm.
6.Application: tug boat, harbor workboat, service ship, ferry and engineering ship
