AI Technical Summary
The existing integrated pump gate has significant leakage at the impeller tip and a large impact from secondary flow. The adjustment effect of the impeller inlet regulating component is poor, and the hydraulic performance and efficiency of the submersible pump need to be improved.
Liquid from the outlet guide vane is introduced into the regulating chamber through the connecting pipeline. The slider and sliding ring self-adjust under the action of liquid pressure, adjusting the axial clearance between the sliding ring and the impeller leading edge and blade tip, thereby reducing blade tip leakage and secondary flow effects.
This improved the hydraulic performance and efficiency of the submersible pump, achieving excellent results in high efficiency and energy saving.
