Purification of the centrifugal fan impeller, if compared with the purchase of the ordinary fan impeller, it can be concluded that there are some differences between them, but the difference is not very large, because on some basic and necessary considerations The same is true for the origin, parameters, quality, price, manufacturer, product use environment and usage requirements of the product, but it will be different in some targeted considerations.
2. Purify the specific form of the centrifugal fan impeller
Purifying the impeller of the centrifugal fan is more complicated than the impeller of the axial flow fan from a professional point of view, and the impeller is the heart of the fan. It is an important component that needs to be taken seriously and treated seriously, so as to avoid the wrong choice. In its specific form, it mainly has the following, which is:
Forward type: The exit angle of the blade has a certain range, which is suitable for occasions where the air volume is generally high and the requirements are relatively high, but it should be noted that the efficiency is not very high.
Radial type: the blade exit angle is 90 degrees, the structure is simple and the production cost is low. The parameters are between the forward type and the backward type, and the work efficiency is not very high. Therefore, it is mainly used in a few occasions such as mines. in.
Backward type: The blade exit angle is less than 90 degrees. It has the advantages of large air volume, small pressure and high efficiency. Its efficiency can reach 80%-90%, which is widely used and not easy to scale. From the current point of view, it is widely used in the industrial and power industries.
3. Purification of centrifugal fan impeller characteristics and parameters
The characteristics of purifying centrifugal fan impeller are high efficiency, low noise and vibration, low temperature rise and stable pressure curve. It can be used in large-scale purification and dust-free engineering, such as air shower, cargo shower, dust-free workshop and experiment. For these places, such as the impeller, the parameters corresponding to the impeller are the flow, total pressure, noise, power, speed and voltage. They are important and basic parameters, and they should not be taken lightly or sloppy.
