What Is The Purpose Of Micro High-pressure Fan

With the development of modern industry, in some situations, traditional centrifugal fans have been unable to meet the needs of industrial production. At this time, micro high-pressure fans appeared. Micro high pressure fans play an important role in these relatively different situations. Let's take a closer look at the uses of micro high-pressure fans.
The smoke exhaust fan box is composed of a low noise forward tilting multi wing centrifugal fan, bearings, motors, transmission parts, anechoic type box, etc. The efficiency of the smoke exhaust fan box is similar to that of the rear bending fan airfoil centrifugal fan. Under variable operating conditions, especially in low load areas, oil smoke exhaust fans with adjustable stationary or movable blades are more economical than centrifugal fans with inlet axial deflector adjustment. For common smoke exhaust fans, in general, we will choose the layout of rear guide vanes for boiler forced draft fans. The rear guide vanes rectify the swirling motion of the air flow at the impeller outlet into an axially moving fan box, improving the power of the fan. The kinetic energy of the airflow through the rear guide vane of the smoke exhaust fan box is still large, accounting for over 30% of the total pressure at high power points.
Therefore, in order to improve the power of the fan, it is necessary to install a diffuser after the rear guide vanes to further convert some kinetic energy into pressure energy. The main types of diffusers are as follows:
The outer diameter of the diffuser is equal, and the inner core is a shortened cone, so that the flow area of the fluid can be added. This type of diffuser is convenient to manufacture and is suitable for occasions where the diameter of the exhaust duct is the same as the outer diameter of the fan.
The diffuser with a dispersed outer cylinder and a convergent core cylinder has a good diffusion effect due to the large addition of dispersed area. It is suitable for situations where the diameter of the exhaust duct is larger than the outer diameter of the fan.
3. Diffuser with equal diameter inner core and dispersed outer cylinder. Its diffuser effect is not as good as the previous one, but because of its simple layout technology, it is also suitable for situations where the diameter of the exhaust duct is larger than the outer diameter of the fan.
Cabinet type centrifugal fan box is a high-quality fan product, with outstanding characteristics such as high efficiency, high temperature resistance, small vibration, light weight, compact structure, and excellent performance. We believe that everyone is not unfamiliar with the fire fan box, and now it has been widely used in auditoriums, theaters, basements, hotels, restaurants, factories, mining enterprises, office buildings, and other places for ventilation and smoke exhaust fan ideal products, It is an updated product of cabinet type centrifugal fan box for high-rise buildings.
To sum up, micro high-pressure fans are suitable for some special occasions because their excellent performance is being chosen by more and more people. Miniature high-pressure fans are widely used because they can be better combined with other machines to play a regulatory role in production.
