75 KW Bow Thruster:
1. 75 KW Bow Thruster Main Function

The main function of this device is to make the power and torque of the motor through the coupling and a pair of speed reducing circular arc bevel gears to the fixed propeller, control the rotation speed and direction of the variable-frequency motor through variable frequency speed regulation, and then make the propeller generate the thrust force towards the port side or the starboard. No matter the degree of thrust force can be adjusted or not, it can raise the mobility and maneuverability at ship navigation.

This device applies to the unrestricted navigation area, the bow thruster cylinder. The grid should be set at the entrance.

2. Composition of equipment

(1)A lateral thrust unit, including the gear box part and standard catheters,propeller, propeller shaft, bevel gear, meshing.

(2)A gravity oil tank

(3)A set of electric control device (Control point is three)

(4)A variable frequency speed regulator

(5)A set of drive motor

(6)Corrosion-resistant Zinc pieces

(7)A set of couplings

(8)A The bridge control panel

3. Interface

(1)Power supply: three phases AC 380 V±10%, 50 HZ±5%

Power supply: AC 220 V±10%, 50 HZ±5% 200 W,DC 24 V±10%,100 W (Applied in alarming unit)

Shipyard shall provide AC three-phase 380 V and AC 220 V and DC 24 V power supply.

(2)Cylinder: the axial reinforced rib and the ring-shaped reinforced rib are set on the cylinder

Standard length of cylinder: 700 mm.

(3)Gravity oil tank: the pipe and the hydraulic oil of the gear box are supplied by the shipyard.

(4)The gear lubricant is the gear lubricant of moderate ultimate pressure N 100, approximately 40 L.
