Working principle of medium pressure fan

The common medium pressure fan is centrifugal fan, the impeller is covered with a mechanical shell, and the center of the impeller is the air inlet. When the medium-pressure fan works, the power equipment runs to drive the impeller to rotate, and the air is sucked in from the air inlet. In the process of centrifugal fan blade rotation, the dynamic effect is exerted on the gas to improve the pressure and speed of the gas.
In the working process of medium pressure fan, although the rotation of impeller increases the pressure and speed of the gas, but the various changes of the gas are small, so in the process of design and use of centrifugal fan, gas is usually treated as an incompressible fluid. The gas treatment process of medium-pressure fan is completed in the same radial plane, so the medium-pressure fan is also called runoff centrifugal fan.
