Marine Hydraulic Transverse Thruster

Marine Hydraulic Transverse Thruster

Application

A marine hydraulic transverse thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It consists of a propeller mounted horizontally in a tunnel on the side of the vessel, perpendicular to the direction of travel, and is powered by a hydraulic system. According to the propeller type, our tunnel thruster are fallen into controllable pitch tunnel thruster(CP Type) and fixed pitch tunnel thruster (FP Type). Our tunnel thruster can be driven by diesel engine, electric motor or hydraulic motor. This one is hydraulic-driven type.It gets power supply from hydraulic pack and generates thruster through propeller rotation. As Compared to electric motor, hydraulic bow thruster has a simple structure which can save a lot of space. Our tunnel thruster is widely used to improve the maneuverability of vessels when docking or steering. We can design and manufacture the product according to client's drawing or sample.

Features

1. Propeller type: FP

2. Propeller dia.: 1100mm-3000mm

3. Power range: 200KW-2930Kw

4. Max.thruster: 46KN-462KN

5. Drive force: diesel engine, electric motor, hydraulic motor.

6. Advantage: less noise and vibration, supper strength, easy installation.

We not only provide customers with high-quality products, but also provide complete system solutions and added services for specific customers. Therefore, There are high competitiveness.

Configuration options

Part Name	Type/Material	Advantages/Disadvantages
Hydraulic Motor Type	DONGFANG and XINHONG brand	Good quality, cost-effective, long service life. With brake, high safety.
Hydraulic Motor Type	Other brands	High power consumption, relatively poor quality.
Propeller	Ni-Al-Bronze (Cu3)	Excellent comprehensive mechanical properties and corrosion resistance.
	Ni-Mn Bronze (Cu2)	High strength, good hardness, good wear resistance, good elasticity, no spark, corrosion resistance, non-magnetic, excellent cold working performance, excellent electroplating and welding performance.
	Manganese Bronze (Cu1)	It has high strength, hardness and good plasticity, can well withstand pressure processing in hot and cold states, has good corrosion resistance, and has high thermal strength.
	Stainless Steel	Good corrosion resistance, high hardness.
Tunnel	WANXIANG / HONGBO	Corrosion resistance, good quality, cost-effective

Due to the fierce market competition, the phenomenon of low quality of other winch suppliers is frequent. What is the difference between us and other low-quality suppliers?

The specific differences are as follows:

Part name	Other low quality suppliers	Result	Our factory	Consequence
Hydraulic Motor Type	Other brands	High power consumption, relatively poor quality.	DONGFANG or XINGHONG brand	Cost-effective, good quality. With brake, high safety.
Propeller	Cast iron	Easy to corrode, easy to rust	Stainless steel	Good corrosion resistance, high hardness
	Cast iron	Easy to corrode, easy to rust	Manganese Bronze (Cu1)	It has high strength, hardness and good plasticity, can well withstand pressure processing in hot and cold states, has good corrosion resistance, and has high thermal strength.
	Brass	Dezincification is easy to occur in seawater, resulting in cavitation corrosion and affecting navigation safety.	Ni-Mn Bronze (Cu2)	High strength, good hardness, good wear resistance, good elasticity, no spark, corrosion resistance, non-magnetic, excellent cold working performance, excellent electroplating and welding performance.
	Brass		Ni-Al-Bronze (Cu3)	Excellent comprehensive mechanical properties, resistance to stress corrosion cracking, corrosion fatigue resistance, cavitation corrosion resistance, erosion resistance, marine biofouling resistance. After heat treatment, it can reach the level of duplex stainless steel. Compared with brass, the corrosion resistance is three times that of brass, and the wear resistance is twice that of brass.
Tunnel	Other brands	Easy to corrode, relatively poor quality	WANXIANG / HONGBO	Corrosion resistance, good quality, cost-effective

Maintenance advice

1. Regularly check whether there is leakage of hydraulic oil in the side thruster of the ship, regularly add tallow to the moving bearings and couplings, and replenish the hydraulic oil of the system in time.

2. Clean the dust in the ship's thruster control panel in time and check the working condition of the ACB.

If the ACB fails to close there are several reasons:

2.1. The control circuit has no electricity;

2.2. The main switch energy storage motor does not store energy normally;

2.3. There is no closing signal to the main switch closing coil;

2.4. The main switch under voltage coil has no electricity.
