| Abstract: |
| 【Background】 groundwater extraction in Hebei Province.【Objective】Scientifically utilizing the hydroelectric conversion coefficient of machine-driven wells and analyzing its variation laws are of great significance for optimizing water resources allocation, saving energy, and improving efficiency.【Method】Based on the relevant monitoring data of 177 agricultural irrigation wells in Cang County, Hebei Province, the factors such as groundwater depth, pump efficiency, pipeline pressure, and water pipeline length that affect the hydroelectric conversion coefficient of the wells were analyzed by single factor, and a regression model was established. The main factors were screened out by the path analysis method, and their accuracy was verified.【Result】The hydroelectric conversion coefficient of the motor-driven well is greatly affected by the buried depth of the groundwater level, and the path coefficient is -0.882. (Pipeline pressure has been eliminated in the model path analysis process).【Conclusion】The calculated and measured water yields of shallow wells and deep wells under different groundwater depths are well fitted, and the fitting accuracy of shallow wells is higher than that of deep wells, and R2 is 0.88 and 0.85. The research results have important practical significance for speeding up the promotion of "electricity to water" metering management measures. |
