Introduce the main technical parameters of the high pressure centrifugal fan

The key parameters of the high-pressure centrifugal fan are the exhaust air volume, the rated power of the motor, the efficiency, the specific sound pressure level, the speed ratio and the rated power of the motor. The selection of high-pressure centrifugal fans should be based on the physical and physical properties of the gas being transported, and the different uses, and different types of high-pressure centrifugal fans should be selected.

When selecting the high-pressure centrifugal fan model, the piping system software should be considered Ventilation damage, data error, and the negative error of the actual air volume and wind pressure of the centrifugal fan, generally choose the safety performance of the air volume of 1.05~1.1, and the wind pressure of 1.10~1.15. However, it is not suitable to choose excessive safety performance, so as to prevent the centrifugal fan from operating in the low efficiency area for a long time.

Matching the frictional resistance characteristics of the pipeline network and the characteristics of the centrifugal fan In order to make the centrifugal fan work smoothly, the centrifugal fan should be recruited near its higher efficiency point Information, the working center of the centrifugal fan is located on the right side of the maximum rated power point of the motor in the characteristic curve (that is, the side with a large amount of wind, and generally located at 80% of the maximum rated power of the motor).

The working efficiency of the fan adopts the design scheme, which should not be less than 90% of the fan efficiency. When choosing a DC variable frequency fan, the total working pressure calculated by the system software should be used The damage is the rated wind pressure, but the rated power of the fan motor should be 15%~20% more than the estimated value. When the working conditions of the fan application (such as gas temperature, atmospheric pressure, etc.) are inconsistent with the working conditions of the fan model, solve the problem. The fan characteristics are adjusted.
