6-24 series centrifugal fan is generally used for gas transportation of granular or powdery materials, and can be widely used to transport air and non-corrosive non-self-igniting, non-viscous substances.
The temperature of the medium generally does not exceed 50°C (max 80°C), the dust and hard particles contained in the medium is not more than 150 mg / m3.
6-24 series centrifugal ventilation fan Structure
6-24 series centrifugal ventilation fan Application
Centrifugal fan is widely used in the cement industry, building materials industry, environmental protection industry, metallurgical industry, power industry projects such as large-scale dust collector, industrial boilers, ventilation systems, cooling.
6-24 series centrifugal ventilation fan Features
According to customer performance requirements customized design, and optimized by CFD technology, the energy consumption is lower than similar models.
For the material of impeller and main spindle, we will choose high-strength carbon steel, low-alloy steel, high-temperature alloy steel, high temperature high-strength alloy steel for different working conditions temperature and working speed, so that the impeller and main spindle at high temperature still maintain reliable strength.
For dusty gas, we can meet all kinds of working conditions from small amount of dust to large amount of dust. After special treatment, the hardness of blade surface can reach HRC60~70, which can extend the life of the impeller by more than 3 times.
The moderate bonding between the components is tight, and the sealing performance is good, ensuring that the output pressure will not be reduced.
After annealed treatment, the internal stress of the structure generated during welding can be completely eliminated to ensure that the impeller will not creepage and crack.
Ultrasonic flaw detection on the welding seam and main spindle of the impeller to ensure that there are no welding defects or material defects and ensure the strength
The impeller is subjected to a high standard of dynamic balancing adjusting to ensure stable operation of the fan.
Test assembly after production is completed to ensure that there is no interference between the components.
Provide on-site arrangement and guidance services.
