Research and design of the computer-aided selection system of the circulation pump based on the performance curve

摘要

Traditional method to select pumps on the basis of several operating parameters is the cause of problems with air conditioning water system pumps and piping, through simulation of the pump performance curve equation, this paper intuitively shows the data of combination operation point of pump and pipe to facilitate the designer timely to adjust scheme and revise design, and writes the corresponding computer program to use the computer to select the pump to achieve the water system design optimization, through checking contrast with a numerical example, the satisfactory result is achieved.
