The electric submersible pump (ESP) is the main equipment for the in-situ leaching uranium industry in China, effectively increasing the production of leaching fluid. However, few studies on the internal flow field subject to rotating-stationary-parts interactions are available in literature. With the internal structure of impeller-guide vane as the research object, CFD method was applied to carry out unsteady analysis on the flow characteristics of the medium, and the variation mechanism of pressure pulsation inside the impeller and the outlet section of the impeller was studied. Moreover, the transient flow field data were used to analyze the pressure flow field in the section of the impeller through the action mode decomposition (DMD) and pressure flow field reconstruction. The periodic variation mechanism of pressure pulsation caused by static and dynamic interference and the influence of distance between static and dynamic components on the intensity of static and dynamic interference are revealed. The results indicate that the frequency values of the blades are basically consistent with those of the Fast Fourier Transform (FFT). These findings offer valuable theoretical underpinnings for mitigating undesirable pump vibrations induced by pressure pulsations, optimizing ESP hydraulic component parameters, and ultimately improving system efficiency.
