Simulation and Experimental Research on Hydraulic Performance of Low-pressure Pipeline Irrigation Systems
This article simulates the hydraulic performance of low-pressure pipeline irrigation systems and analyzes them based on experimental data.Two flow monitoring points and five pressure monitoring points were set up at the pump station outlet and other locations in a fully enclosed low-pressure pipe rotation irrigation area as the experimental object.Design four treatments to explore the hydraulic performance of irrigation systems under different treatments.The experiment shows that the observed values of pipeline pressure and flow rate are basically consistent with the theoretical values,with a high degree of fitting,indicating the reliability of the hydraulic simulation method;Ensuring that the number of water outlets matches the designed flow rate of the water pump,adopting flower arrangement and selecting variable frequency adjustable water pumps can improve the efficiency of water pump operation and save operating costs.
