Working conditions

02 Application Scenarios

The 4-68 centrifugal fan can be used for both gas input and output. The gas transported by the 4-68 fan should mostly be air at a temperature not exceeding 80 ℃ and other gases that are not prone to spontaneous combustion, harmless to the human body, and non corrosive to steel materials. The gas must not contain viscous substances, and the amount of dust and hard particles should not exceed 150mg/m3.

Used for building ventilation, material ventilation and drying, air purification and industrial waste gas treatment, industrial dust collectors, air purification and emissions in hazardous working environments (paper production lines, electrolytic aluminum production lines, textile factories...). Boiler and brick kiln blowing, transportation of various gases, transportation of particles/powders/debris/fiber materials, etc.

03 Equipment Configuration

04 Processing Technology

● Fan form: motor direct connection, belt drive, coupling drive;

● Motors *: Innovative Motors, Lu'an Motors, Wannan Motors, ABB， Siemens and other well-known companies both domestically and internationally (can be specified);

● Impeller: * Carbon steel, stainless steel, rubber lining, wear-resistant layer or wear-resistant lining plate, ceramic patch (can be specified);

● Bearings: SKF、FAG、 Wafangdian, NSK (can be specified);

● Spindle: High strength carbon steel, composite steel

● Bearing seat: cast iron

● Optional configuration: ※ Overall bracket; ※ Protective cover; ※ Silencer; ※ Import and export compensator; Import and export matching flange; ※ Adjust the door; ※ Electric actuator; ※ Shock absorber; ※ Diaphragm coupling; ※ Hydraulic coupling; ※ Motor rain cover; ※ Temperature sensor; ※ Vibration sensor; ※ Soft start device; ※ Frequency converter;

The front, rear, and middle plates of the impeller are all cut using laser cutting machines to ensure the accuracy of the profile and reduce thermal deformation;

The front plate, rear plate, and middle plate of the impeller are all pressed into shape using specialized molds on a cantilever press;

The impeller welding adopts robot welding or manual arc welding method, and the preheating of the workpiece and the welding rod are carried out according to the standard;

The impeller undergoes annealing treatment to eliminate the structural internal stress generated during welding, ensuring that the impeller does not crack;

The welds of the impeller and the main shaft have undergone ultrasonic testing to ensure that there are no welding defects or material defects, ensuring strength;

The impeller undergoes dynamic and static balance correction, with a balance accuracy of ≤ 2.5 levels.
