Although there is only one word difference between the axial flow fan and the diagonal flow fan, the difference between the two is still very large. The two have different uses, different principles, and different functions.
Axial flow fans are very widely used, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans, air conditioner outdoor fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are usually used in applications with high flow requirements and low pressure requirements. Axial fans fix the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high.
The oblique flow fan is also called the mixed flow fan. In this type of fan, the gas enters the impeller at an angle to the axis, obtains energy in the blade passages, and exits in an oblique direction. The shape of the impeller and casing of the fan is conical. This fan is a combination of centrifugal and axial flow, with flow ranges and efficiencies in between.
Axial flow fan is a fan with airflow in the same direction as the axis of the blade. The gas flows parallel to the axis of the fan, which does not change the flow direction of the gas, thereby reducing the resistance to the gas. There are three installation methods for the axial flow fan: vertical, Horizontal, inclined. Axial flow fans vary in size. Small impellers are only about 10 cm in diameter, and large ones can reach more than 20 meters. Axial flow fans have low power consumption, low noise, low wind pressure and large flow. , food, medicine and other industries for ventilation or to speed up heat dissipation.
Diagonal flow fans, also known as mixed flow fans, are usually made of steel, glass fiber reinforced plastic, and aluminum as the main materials. Diagonal flow fans are composed of motors, impellers, inner and outer cylinders, imported current collectors, and guide vanes. The meridian acceleration method has greatly improved the working efficiency of the fan. The diagonal flow fan is generally used as the first choice for ventilation and ventilation in factories and buildings. It can not only discharge gas, but also input gas, and has a variety of application methods. The different requirements of users can be transformed, so that one machine can be used for two purposes. Although the wind speed at the outlet of the diagonal flow fan is much higher than that of the axial flow fan, its flow rate is still smaller than that of the axial flow fan.
Each type of fan has its own advantages and disadvantages, and each type of fan has its own function. Axial flow fans can be used in industries that require wind pressure due to large air pressure and small flow. Diagonal flow fans have large flow and small air pressure. It can be used in industries that require flow. The reason why each type of fan has not been eliminated is because they have different needs.
