Introduction
A marine axial flow fan is a type of fan commonly used in marine applications, particularly in ventilation systems for ships and other sea vessels.
An axial flow fan works by pulling air through the fan blades parallel to the axis of rotation, creating a continuous flow of air. The design of the fan blades allows for a large volume of air to be moved at a relatively low pressure, making them suitable for ventilation systems in which the air resistance is relatively low.
Features
The fans are designed according to arbitrary vortex flow method. We choose the most reasonable vortex flow coefficient on the basis of the fans, specification, distribute every sectional characteristic speed & length of the vanes, make full use of the high peripheral velocity of the vane point. Therefore, they have the features of high-efficiency, low-noise, large-flow & pressure coefficient, light-weight, etc.
In the curse of designing & manufacturing, we had thought fully of the marine special conditions, they impellers are strictly made by dynamic balance adjustment & over speed test. Therefore, the fans also have the features of good-corrosive resistance, resistance to swing, resistance to shock and vibration, stable turning, safety & reliability, etc.
Installation type of axial fan
Viewed from the motor side, the impeller rotates clockwise.
In general, fan is vertical structure, and if necessary it can also be made in structure with frame.

Advantages / disadvantages |
|
Casing |
Carbon steel |
After heat treatment, higher hardness and better wear resistance can be obtained. The hardness in the annealed state is very moderate, and it also has good machinability. Raw materials are very common, easy to obtain, and the production cost is relatively low |
|
Impeller |
Aluminium alloy |
Low density, high strength, good conductivity, good corrosion resistance and easy processing |
|
Electric machinery |
|
Finished marine motor with low noise, low vibration and high protection grade |
|
Junction box |
Q235A |
It has good plasticity and welding performance, good forming ability, and has a certain strength. It is suitable for engineering structures. It has good practical performance, relatively cheap price and high cost performance |
|
Stationary blade support foot |
Q235A |
Ordinary carbon structural steel has simple production process, good process performance (such as welding performance, pressure processing performance, etc.), necessary toughness, good plasticity, low price and easy to supply in large quantities. It is usually used after hot rolling |
|
Casing flange |
Q235A |
Good toughness and plasticity, certain elongation, good welding performance and hot workability |

Incorrect model selection and differences |
The air volume and pressure cannot meet the customer's requirements |
The air volume and pressure cannot meet the customer's requirements |
The air volume and pressure meet the requirements, and the operation is stable and safe |
|
Use inferior materials and turn out substandard goods |
The casing is easy to rust |
Adopt marine standard carbon steel |
|
|
Impeller not durable |
It is easy to be corroded by seawater in a short time, resulting in air holes in the impeller and reduced air volume |
Adopt Marine Standard 104 aluminum alloy |
More corrosion resistance and longer service life |
|
Choose ordinary motor as marine motor |
The insulation grade cannot meet the requirements |
Strictly select marine motor |
The shell has higher protection grade, certain explosion-proof property, more moisture and corrosion resistance, and longer service life |
|
The explosion-proof grade is not selected as required |
The motor fails to meet the explosion-proof requirements and is prone to danger |
Choose explosion-proof grade in strict accordance with application requirements |
