According to the cross section of the wheel surface, the impeller can be divided into several types
Hyperbolic impeller: This impeller wheel in the section along the radial hyperbola, complex processing, only used in some turbine control stageThe strength of the impeller: the impeller is provided with a center hole, the highest strength, used for disc welding or high speed single stage steam turbine rotor
Conical impeller: the thickness of the section of the impeller surface is tapered along the radial direction, and is widely used in the packaged impeller
Equal thickness impeller: the thickness of the cross section of the impeller surface is equal to that of the lower speed of the circle
