DESIGN METHOD OF TWO VANE PUMP IMPELLER FOR WASTEWATER TREATMENT

摘要

The present invention relates to a method for designing an impeller of a two-vane pump for wastewater, and more particularly, to a method for designing an impeller of a two-vane pump for wastewater for designing a two-vane pump of a desired specification. In the impeller design method of the two vane pump for wastewater, the configuration of the present invention for achieving the above object is formed to extend outwardly from the pump inlet in a streamlined shape and has a pair of mutually symmetrical impellers, a) the objective function setting up; b) setting design parameters for deriving the set objective function; c) setting maximum and minimum values of the design variables; d) deriving the value of the objective function according to the set value of the design variable through numerical analysis; e) deriving a linear function expression for deriving the value of the objective function by using the value of the objective function according to the derived value of the design variable; and f) deriving the value of the design variable that satisfies the design objective function value as a design plan using the derived first-order function formula.
