To solve the industry’s technical pain points of traditional deep well pumps, such as high hydraulic loss, turbulent water flow and unstable water output, Jinyu Pump has achieved technical innovation in the core hydraulic system and fully adopted CFD fluid simulation technology for product research and development. Through digital modeling, the R&D team accurately simulates water flow trajectories, pressure distribution and velocity changes in complex deep well water environments, and optimizes the impeller surface radian, guide vane angle and pump cavity flow channel structure. This effectively eliminates eddy currents, water accumulation and hydraulic loss during pump operation. After the technical upgrade, the overall hydraulic efficiency of Jinyu Pump deep well pumps has been significantly improved with more stable water delivery and no idling loss, delivering excellent performance under low water level and large-flow water intake conditions in deep wells. The large-scale application of fluid simulation technology has upgraded Jinyu Pump’s hydraulic design from traditional empirical methods to digital precision R&D, greatly enhancing core hydraulic performance and leading the industry in technical level.
