Centrifugal fan selection precautions

 

1. Before choosing a centrifugal fan, you should understand the production and product quality of domestic centrifugal fans, such as the variety and specifications of centrifugal fans produced, the special uses of various products, the development and promotion of new products, etc., and environmental protection should also be fully considered. requirements in order to choose the best fan.

 

2. According to the different physical and chemical properties of the gas conveyed by the centrifugal fan, choose the centrifugal fan for different purposes. Explosion-proof fans should be selected for transporting explosive and flammable gases; dust exhaust or pulverized coal fans should be selected for transporting dust or pulverized coal; anti-corrosion centrifugal fans should be selected for transporting corrosive gases; High temperature centrifugal fans should be selected for conveying high temperature gas.

 

3. When there are more than two kinds of centrifugal fans to choose from on the fan selection performance chart, the higher efficiency and smaller machine number should be preferred: the one with a larger adjustment range, of course, should be compared and weighed Decided on pros and cons.

 

4. If the diameter of the impeller of the selected fan is much larger than that of the original fan, in order to use the original motor shaft, bearings and supports, etc., the motor startup time, the strength of the original fan parts and the criticality of the shaft must be checked. Calculate the speed, etc.

 

5. When the centrifugal fan is selected, when the motor power it is equipped with is less than or equal to 75KW, it is not necessary to install the valve only for starting. When the centrifugal boiler induced draft fan is selected to discharge high temperature flue gas or air, a valve for starting should be set to prevent overload during cold operation.

6. When choosing a centrifugal fan, try to avoid using centrifugal fans to work in parallel or in series. When it is unavoidable, centrifugal fans of the same type and performance should be selected to work together. When a series connection is used, there should be a certain pipeline connection between the first-stage centrifugal fan and the second-stage high-pressure hot air fan.

 

7. The selected new centrifugal fan should consider issues such as making full use of the original equipment, suitable for on-site production and installation, and safe operation.

 

8. For the centrifugal fan system with noise reduction requirements, the centrifugal fan with high efficiency and low impeller peripheral speed should be selected first, and it should work at a higher efficiency point; it should also be based on the transmission mode of noise and vibration generated by the ventilation system. Take appropriate noise and vibration reduction measures.
