what is the difference between axial fan and centrifugal fan? Comparison of economic benefits
Fans are mainly used in metallurgy, petrochemical, electric power, urban rail transportation, textile, shipping and other areas of the national economy and a variety of places for ventilation. With the continuous intensification of competition in the fan manufacturing industry, mergers and acquisitions between large fan manufacturing enterprises integration and capital operation is increasingly frequent, the domestic outstanding fan manufacturing enterprises pay more and more attention to the study of the industry market, especially on the industrial development environment and product buyers in-depth study.
General ventilation fan (generally small and medium-sized centrifugal and axial flow ventilators) is the most widely used, for people common centrifugal fan and axial flow fan difference is what?
Axial fan and centrifugal fan difference
1, the exhaust direction is different: axial fan exhaust direction is along the direction of the axis of the straight row, fan air inlet and exhaust is in an axis parallel line, centrifugal fan exhaust direction is perpendicular to the direction of the air inlet, can be realized in 360 degrees of the specified direction of the exhaust.

2, the degree of difficulty in the installation is different: axial fan installation is relatively simple, generally installed directly on the wall or connected to the duct. Centrifugal fan installation is more complex.
3, the different air volume and wind pressure: axial fan air volume and wind pressure is relatively small, basically nothing wind pressure, while the centrifugal fan air volume and wind pressure are relatively large, if the pipeline elbow is more, pumping distance and air distance are relatively far, pipe resistance, you must use centrifugal fan.
4, the appearance of different shapes: axial fan appearance is basically cylindrical, centrifugal fan appearance is snail-shaped.
Fan motor connection is different: axial fan motor connection is generally in the body of the fan, centrifugal fan motor are connected by the shaft, generally external in the fan outside the extraction cylinder.
Axial fans and centrifugal fans are mainly used
Axial fans and centrifugal fans are two different products within the fan category, the main function is also the environment of the air ventilation equipment.
1, axial fan, the use of a very wide range, is the same direction as the axis of the blade of the air flow, such as electric fans, air conditioning fan is an axial flow way to run the fan. The reason why called "axial", because the gas flows parallel to the fan axis. Axial fans are usually used in applications where the flow rate is high and the pressure is low. Axial fans are fixed in position and move air. Axial fans are mainly composed of fan impeller and casing, simple structure but very high data requirements.
2, centrifugal fan is rely on the input of mechanical energy, increase gas pressure and discharge gas machinery, it is a kind of slave fluid machinery. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household electrical equipment; drying and selection of grain; wind tunnel wind source and hovercraft inflation and propulsion, etc.
Summarize
With the continuous development of science and technology, people use the centrifugal fan requirements are getting higher and higher, the current global centrifugal fan technology development trend, centrifugal fan capacity will continue to increase, high efficiency, high speed miniaturization and low noise direction. Large centrifugal fan capacity continues to increase. With the large-scale industrial installations, the need for various types of centrifugal fan capacity is also increasing, the number of centrifugal fans in the next few years in the market will increase.
