Material

Advantages/Disadvantages

Shell

Carbon Steel

Higher hardness and better wear resistance can be obtained after heat treatment. The hardness in the annealed state is very moderate, and it also has good machinability. Raw materials are very common, simple and easy to obtain, and the production cost is relatively low.

Impeller

Aluminium Alloy

Low density, high strength, good electrical and thermal conductivity, good corrosion resistance, easy processing.

Motor

Finished marine motor with low noise, low vibration and high protection level.

Junction Box

Q235A

It has good plasticity and welding performance, good forming ability, all many profiles, and has a certain strength, suitable for engineering structures, good practical performance, relatively cheap price, and high cost performance.

Static leaf support

Q235A

Ordinary carbon structural steel has a simple production process, good process performance (such as welding performance, pressure processing performance, etc.), necessary toughness, good plasticity, cheap and easy to supply in large quantities, and is usually used after hot rolling.

Static blades brace

Q235A

It has good toughness and plasticity, has a certain elongation, and has good welding performance and hot workability.

Result

Incorrect selection, there are differences

Air volume and air pressure can not meet customer requirements

Selection in strict accordance with customer requirements

The air volume and air pressure meet the requirements, the operation is stable, and the use is safe

Chassis material cut corners

The case is easy to rust

Made of marine standard carbon steel

The casing meets the requirements, and the fan can be used for a longer time

Impeller cut corners

It will be easily corroded by seawater in a short time, resulting in pores in the impeller and reduced air volume

Adopt marine standard 104 aluminum alloy

More corrosion resistant, longer service life

Choose a common motor for use as a marine motor

The insulation level does not meet the requirements

Strictly select marine motors

The shell has a higher protection level, has a certain explosion-proof property, is more resistant to moisture and corrosion, and has a longer service life

In order to reduce costs, even aluminum wire and copper-clad aluminum wire are used as coils

No problem can be seen in a short time, but often after the shelf life expires, problems follow

Using standard marine motor coils

The product is safe to use and has little risk. Fans last longer and.

Manual cutting

Manufacturing accuracy is difficult to guarantee, and products often fail to achieve rated performance

Using CNC plasma cutting, according to one-to-one drawing size

High precision, good molding, stable operation, and achieve rated performance parameters
