PIPE DIAMETER SETTING METHOD ACCORDING TO BALANCING ANALYSIS ABOUT TERMINAL FLOW RATE AND FLOW PRESSURE FOR OPTIMUM DESIGN OF PIPE SYSTEM

摘要

PURPOSE: caliber setting method, the flow velocity for solving unbalance generation is provided about flow velocity and flowing pressure pipe-line system optimization design according to equilibrium analysis for terminal and pressure designs pipe-line system on each terminal. CONSTITUTION: the setting method of caliber, terminal include: optimization design first step input number information conduit system about flow velocity and flowing pressure pipe-line system according to equilibrium analysis, select the characteristic curve of pump, flow velocity and pressure, need to each terminal; Second step calculates selected head and is based on input information calculating flow conduit; The friction loss of third step calculates respective conduit, then calculates total friction head; The step of front, identifies the total friction head of difference; 5th step selects currently selected caliber, if difference is less than specified value; With 13 step of the 6th Step-and-repeat.
