 NRP series azimuth thruster (FP/CP)

NGC is able to supply azimuth thruster lines with fixed pitch or controllable pitch propellers according to customer needs. Arranged in Z-Drive or L-Drive, the azimuth thruster transforms reliablely the power of diesel engine, electic motor or hydraulic motor into best thrust and thus improves propulsion effeciency and maneuverability.

Input power锛150 锝 4500 kW
Input speed锛500 锝 1800rpm
Blade diameter锛1100mm 锝 4500mm

Product application

鈻  Materials of propeller, bevel gear and drive shaft are supplied by a NGC-hold alloy steel and bronze parts manufacturer.
鈻  Propeller blade of low RPM and large diameter is matched with the high efficiency nozzle to improve the thruster efficiency and lower down the noise and vibration.
鈻  Modularized rudder propeller structure simplifies the system and makes the components easier to interchange and maintain.
鈻  Bevel gears are designed and machined in house to high precision, strong loading capacity and long service life.
鈻  Clutch: built-in hydraulic or air pressure controlled clutch, external hydraulic clutch with reduction gear.
鈻  The accurate remote system is simple to operate, sensitive to respond and reliable during navigation.
鈻  Steering type: hydraulic or electric motor drive.

NRP6000 remote system is a follow-up propulsion control system based on PLC controller. The steering control and main engine speed control can be done through a combined control handle in the bridge console. Rotate the handle horizontally, and the rudder propeller can be rotated around 360掳, and move the handle forward and backward to govern the speed of the main engine. In case of the follow-up system failure, you can actuate the back up control system quickly to control the rotation and main engine speed, or can transfer to local engine control and rotation control.
