The inner circle of the sealing ring abuts against the impeller to seal, the impeller can generate certain circumferential floating in the high-speed rotating process, the sealing ring can move along with the impeller, the sealing performance is guaranteed, the impact on the flexible sealing and the pump shell is reduced, and the service life is prolonged.
Preferably, the upper surface of the sealing upper cover is provided with an annular groove. The annular groove provides certain elasticity for the sealing upper cover, so that the sealing upper cover is conveniently arranged in the sealing lower cover and tightly propped against the inner vertical surface of the sealing lower cover to avoid separation.
Preferably, a plurality of axial grooves are uniformly distributed on the circumferential direction of the inner surface of the upper sealing cover, so that the elasticity of the upper sealing cover is improved.
Preferably, the top of the outer surface of the upper sealing cover is provided with a convex ring for limiting the assembly of the upper sealing cover and avoiding over-tightening or over-loosening the lower sealing ring.
The beneficial effects of the utility model reside in that: 1. install an inducer in the pivot in the water inlet section of multistage immersible pump one-level impeller below the bottom, produce an axial thrust to near water to make water up flow, increase the flow property of water, thereby improve water pump efficiency, can also plan the debris of great volume, reduce the impact of debris to water pump impeller, this structrual installation is simple, and the practicality is strong.
2. The sealing ring of the flexible seal can move along with the impeller when the impeller can float in the circumferential direction in the high-speed rotating process, so that the sealing performance is ensured, the impact on the flexible seal and the pump shell is reduced, and the service life is prolonged.
