Welding between tunnel thruster and hull:
Installation between motor and tunnel thruster unit
The piping connection between gravity oil tank and tunnel thruster unit, the connection and installation of the oil pipeline, the piping line cleaning in accordance with CCS regulations and rules.
The installation between remote control system and W/H.
All external cables are provided and installed by the shipyard.
VDR interface
Motor speed signal(4-20mA/-100%-+100%)
Motor current signal (4-20mA/0-110%motor rated current)
Motor operation signal(dry contact signal, closure operation)
Tunnel Thruster
The device's main function is to use the power from Motor-coupling-reducing gear box through fixed pitch tunnel thruster then produces the thrust. The converter motor drives the fixed pitch tunnel thruster ,whose frequency and phase decides the thrust's position and size.
.
6.2.Environmental conditions
The tunnel thruster works at below environmental conditions
Relative humidity:60%±3%
Environment temperature:0ºC -- +45ºC
Pitch: ±7.5°Trim:±5°
60%±3% :0ºC -- +45ºC
±22.5° :±15°
±7.5° :±5°
6.3. Electrical control system
The basic function of electrical control system include 3 parts: servo control and propeller's speed, current indicator ,provides the remote control through converter motor for the tunnel thruster device and the alarm indication for failure of tunnel thruster system.
Servo control system: control the rotation direction and speed for the driven motor and guarantees its' working current no more than the rated current, the tachometer indicates the speed and rotation direction, ammeter indicates the current of driven motor. Both of them are fixed in the W/H control panel..
The way of variable frequency starting to the motor guarantees its' starting current no more than 1.1times rated ones..
The frequency starting cabinet provided switching functions of local/remote starting for the tunnel thruster which can start/stop the driven motor in the engine compartment or bridge.
