Research on Optimization Method for Stable Operating Point of Water Pump Based on Python
The determination of stable operating points for water pumps is crucial for improving the operational performance and efficiency of water supply pumping stations.Based on Python programming language,a software was developed to calculate the stable working condition point of the pump,and the mathematical model of the stable working condition point of the pump was optimized by fully considering the head loss of the pipeline in the inlet and outlet sections of the pump.According to the known hydraulic parameters of the water supply pump sta-tion,the pipeline head loss parameters and pump characteristic curve parameters of different pipe sections were calculated,the pipeline char-acteristic curve,the pump characteristic curve and the flow-efficiency curve were drawn,and the pump stable working conditions of different terrain heads were quickly determined.Taking the Yinye to Chang Water Supply Project as an example,the practical application of the soft-ware was carried out.The application situation shows that when the KQSN350-M6 pump is located at the topographic lift of 52.6 m,the maxi-mum working lift is 81.53 m,but it still does not meet the requirements of the design lift of 83.00 m.When the reselected SD250-600A pump is located at the topographic lift of 52.6 m,the maximum working lift is 83.96 m,which meets the design lift requirements.
