Based on the goal of comprehensive utilization of sediment in the Yellow River, a complete sediment pumping and conveying system is designed. The main design research content: (1) Analyze the characteristics of the river basin in the middle and lower reaches of the Yellow River, determine the target working conditions according to the types, particle diameters, density and other parameters contained in the Yellow River, and determine the working capacity requirements of the entire sediment pumping and conveying system. (2) Provide the configuration scheme with the overall configuration plan, including the type, model, number of slurry pumps, the length of the slurry pipeline, the caliber of the pipeline and the driving equipment of the mud pump. (3) According to the determined target working conditions and designed working capacity requirements, calculate the flow rate and discharge pressure of the working environment, and then select the mud pump according to the flow rate and discharge pressure, and determine the rated rotational speed, rated power of the drive equipment and other parameters. (4) Complete the matching of the parameters of the mud pump and the slurry pipeline, and the matching of the driving equipment and the mud pump, so as to achieve the highest efficiency of the equipment operation under the conditions of the target working conditions.
