Navy Explosion Proof Axial Flow Fan
Introduction
An explosion-proof axial flow fan is a type of industrial fan designed to operate in hazardous environments where explosive gases, dust, or other combustible materials may be present. These fans are typically used in industries such as oil and gas, petrochemical, mining, and chemical processing, where safety is a primary concern.
The design of an explosion-proof axial flow fan includes features that prevent sparks or other sources of ignition from occurring within the fan or in the environment surrounding it. The fan housing is constructed from materials that are non-sparking and able to withstand an explosion without rupturing. The electrical components are also designed to prevent sparking, and the wiring is contained within conduit or armored cable.
Explosion-proof axial flow fans are available in various sizes and configurations to meet the specific requirements of different applications. They are typically used for ventilation, exhaust, or air circulation in hazardous areas, and can be mounted in a variety of orientations, such as ceiling, wall, or floor-mounted. They are also often designed to operate at high temperatures or in harsh environmental conditions, such as corrosive or abrasive atmospheres.
In summary, an explosion-proof axial flow fan is a specialized industrial fan designed to provide ventilation or air circulation in hazardous environments, such as those found in the oil and gas, petrochemical, and chemical processing industries. Its design includes features that prevent sparks or other sources of ignition from occurring and it must be certified to meet specific industry standards for explosion-proof equipment.
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

Result |
|
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 |
