Description

Technical Field

[0001] The utility model relates to the technical field of impellers, in particular to an integrated waterproof impeller. Background Art

[0002] The main working principle of various pumps is to use a motor to drive the impeller to rotate. During the rotation of the impeller, the fluid flows in from one side and rotates under the drive of the impeller, thereby accelerating the flow of the fluid under the action of centrifugal force; the impeller and related connection structure are the main structures to ensure the performance of the pump body.

[0003] For example, Chinese patent CN221723095U discloses a centrifugal pump impeller, which connects the centrifugal pump impeller body to the rotating shaft through a connecting shaft ring, strengthens the connection strength through limiting teeth and grooves, improves the stability of the impeller during rotation, and fixes the first shaft ring sleeve to the centrifugal pump impeller body through a first reinforcing bolt, thereby improving the overall connection strength.

[0004] However, the centrifugal pump impeller is connected to the drive motor shaft through a connecting shaft ring; and there may be water leakage between the connecting shaft ring and the centrifugal pump impeller, resulting in the water flow not being accelerated by the blades but flowing directly through the connecting shaft ring and the centrifugal pump impeller to the other side of the impeller.

[0005] Based on this, the present invention designs an integrated waterproof impeller to solve the above problems. Utility Model Content
