1, the impeller is an important part of the flow machinery, its main role is to convert the kinetic energy of the mechanical or motor output into fluid kinetic energy, and then make the fluid produce pressure and flow. The role of the impeller is similar to that of a turbine, but much more complex and elaborate. Different types of impellers are suitable for different types of fluids, such as liquids, gases and mixtures.

2. Compression

3. Mixing and stirring

1. Compressor impeller: mainly used for compressed gas, such as internal combustion engines and air compressors.
2. Rotor: mainly used to rotate the fluid and transfer its kinetic energy to other mechanical components, such as centrifugal pumps and turbochargers.
3. Mixing impeller: mainly used for mixing gases and liquids, such as jet engines and mixers.
