The difference between the three types of fans
China Centrifugal Fan supplier - There are many types of fans. The three types of axial flow fans, diagonal flow fans and cross flow fans are more common. What is the difference between axial flow fans, cross flow fans and diagonal flow fans?Now we will introduce the difference between the three types of fans:
1. Axial fan
When the axial flow fan is in the ventilation work, the engine drive impeller rotates in the cylindrical casing, and the gas enters from the collector. According to the impeller, the kinetic energy is obtained to increase the working pressure and speed, and then is discharged in the radial direction. There are three types of layouts for axial flow fans: column, vertical and skewed. Small and medium-sized impellers are only up to 100 mm in diameter, and large and medium-sized impellers are above 20 meters. This is also the key difference between axial fans and other types of fans.
2. Cross flow fan
The cross-flow fan is also quite different from others. The cross-flow fan is a small and medium-sized high-pressure suction filter fan with a forward multi-wing impeller. The gas enters the impeller from one side of the edge of the motor rotor, and then exits from the other side across the interior of the impeller. The gas is subjected to the force of the leaves twice in the impeller. Under the standard of the same characteristics, its specifications are small and the speed ratio is low.
From these many, we can see that the cross flow fan can be said to be a kind of high efficiency and higher application. Because the total width of the cross flow fan can be adjusted at will, and it is not easy to suffer from the hazard of gas. In spite of this, it does not mean that cross-flow fans can be selected for every site. This requires the customer to carry out a very good identification and selection based on the specific situation.
3. Oblique flow fan
The oblique flow fan is also called a mixed-flow fan. In this type of fan, the gas enters the impeller at a certain angle of view from the centerline, obtains kinetic energy in the blade channel, and discharges in a skewed direction. The impeller and casing of the ventilator are tapered. This type of fan combines the characteristics of a centrifugal fan and an axial fan, and the total flow range and high efficiency are close to each other.
