Pressure Pulsation Characteristics of Agricultural Irrigation Pumps under Cavitation Conditions
Agricultural irrigation pumps are the main agricultural irrigation machinery, and their performance is closely related to the flow characteristics inside them. This paper combines experimental research and numerical simulation analysis. Based on the good agreement between the experimental results and numerical simulation data, this paper focuses on studying the characteristics of pressure fluctuations of agricultural irrigation pumps under cavitation conditions. The study found that under non-cavitation conditions, the pressure fluctuations at different monitoring points in pumps with different numbers of blades showed periodic variations, which are related to the number of blades. Under cavitation conditions, the pressure fluctuation coefficients of agricultural irrigation pumps with different impeller blade numbers increased, with a significant impact on the distribution of radial forces on the impeller. The research results supplement the relevant theoretical analysis and have certain practical significance for the application of agricultural irrigation pumps to practical production.
