Marine Explosion Proof Centrifugal Fan

Marine Explosion Proof Centrifugal Fan

1. General
Marine Explosion Proof Centrifugal Fan is a type of centrifugal fan that is designed to operate in hazardous environments where explosive gases, vapors, or dust may be present. These fans are commonly used in marine applications, such as ventilation systems in ships, oil rigs, and other offshore installations.

2. Configuration Options

Name of Parts

Material

Advantages/Disadvantages

Shell

Carbon Steel

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.

Impeller

Aluminium Alloy

Aluminum is a lightweight and durable material that is also resistant to corrosion. It is often used in marine centrifugal fans that require high-speed operation


Motor

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

3. Specific Difference Between Us and Other Suppliers

Comparison

Other low quality supplier

Consequence

Our Factory

Result

poor design, inferior materials, or inadequate manufacturing processes


can result in higher energy consumption, increased operating costs, and reduced performance.


High quality materials are used and the design is carried out according to the standard

Reduce operating costs and improve performance

poor design or improper balancing

produce excessive noise

Standard design

Low Noise

Incorrect selection, there are differences, and the air volume and air pressure cannot meet customer requirements

The use efficiency of the fan is low, the expected effect is not achieved, and the service life of the fan is short

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 product is corrosion-resistant and lasts longer

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

4. Features
The main feature of a Marine Explosion Proof Centrifugal Fan is its ability to prevent sparks or ignition sources that may trigger an explosion in the surrounding environment. These fans are typically constructed using materials that are resistant to corrosion and explosion, such as stainless steel or aluminum. In addition, they are designed with special features such as spark-proof motors, explosion-proof switches, and grounding wires.
5. Operation

The operation of a Marine Explosion Proof Centrifugal Fan is similar to that of a regular centrifugal fan. It consists of an impeller that rotates at high speeds, generating a flow of air or gas that is directed through a housing and out through an outlet duct. The fan may be single or multi-stage, depending on the specific application.

6. Failure analysis and maintenance

Fault Characteristics

main reason

Method of exclusion

Abnormal sounds and vibrations

Loose connecting bolts or insufficient foundation stiffness

Tighten the connecting bolts or strengthen the foundation

The deformation of the impeller, casing or inlet current collector causes mutual friction

Repair Impeller, Casing or Inlet Collector

Impeller damaged or deformed

The blade is attached with uneven attachment; the balance weight is loose; the rivet is loose

Clean and wipe the attachments; fix the balance block firmly; replace the new impeller and level and align; re-balance when necessary

The case is overheating

Valve closed, long run time

Stop and adjust the valve after cooling
