During the operation of the medium pressure centrifugal fan, the rotation of the impeller increases the pressure and speed of the gas, and the various changes of the gas during the operation are small. Therefore, in the design and use of the centrifugal fan, it is usually The gas is treated as an incompressible fluid. The gas treatment process of the medium pressure fan is completed in the same radial plane, so the medium pressure fan is also called the radial flow centrifugal fan.
Performance parameters of medium pressure centrifugal fan
Among the performance parameters of the medium-pressure centrifugal fan, the gas flow, pressure, power delivered, efficiency, and impeller speed are all important in the selection process. The gas flow parameter of the medium pressure fan represents the volume of gas that the fan can handle in a unit time, and the pressure of the medium pressure fan refers to the internal gas pressure value during the operation of the medium pressure fan.
The efficiency of the medium pressure centrifugal fan mainly refers to the ratio between the shaft power of the medium pressure fan and the effective power of the actual process gas. The full-pressure efficiency of the centrifugal fan is about 90%, and in the future development of the centrifugal fan, the efficiency value will be one of the goals pursued by the researchers.
