Marine Axial Flow Fan

Casing	Impeller	Motor

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.

Configuration selection:

Part name	Texture of material	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

Drawing:

The specific differences are as follows:

Product of other low-quality suppliers		Product of our factory

Other low quality suppliers	Consequence	Our factory	Use effect
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
