1. Model conversion method. The method is simple and reliable. The specific method is to first and the design of a centrifugal pump similar to the centrifugal pump, the flow of all parts of the geometry of the size of all enlarged or reduced.
2. Velocity coefficient method. Compared to the velocity coefficient method in essence that is also a similar design method and model conversion method. The difference is that it is based on a series of similar
centrifugal pump based, rather than to build on a similar centrifugal pump based on. That is, the velocity coefficient method is based on the similarity principle, the use of a series of excellent centrifugal pump statistical coefficient calculation of the main dimensions of the impeller.
3. Theoretical calculation method. Based on the basic equation of vane pump, the outer diameter of the impeller and the outlet angle of the impeller are calculated accurately.
