Impeller structure of vortex pump

Technical Field

The utility model relates to a vortex pump, in particular to an impeller structure in the vortex pump.

Background

The vortex pump is used for realizing the promotion to water source ground water, and the structure includes the hollow pump body. The impeller is arranged in the pump body, the wheel shaft of the impeller extends out of the outer side of the pump body and is used for being in transmission connection with the motor, and the impeller rotates to generate centrifugal force under the driving of the motor, so that the water is lifted. The existing impeller structure comprises a disc-shaped impeller body, wherein a plurality of blades are arranged on the impeller body, the blades are straight blades, the blades are arranged on the impeller body in the radial direction, and the blades are uniformly distributed in the circumferential direction of the impeller body.

Chinese patent document (publication number: CN 207647834U) discloses a water pump impeller, which solves the problems of inconvenient processing, relative heavy weight and high cost of the existing single water pump impeller, and adopts the technical proposal that: the cover plate and the blades are formed by stamping the stainless steel sheet, the two cover plates are coaxially connected and fixed together, the cover plates form an arch towards one side in the stamping forming process, and after the two cover plates are attached and fixed together, sharp edges are formed at the periphery of the body. Form the socket on the blade that forms of processing, the sharp edge department of body has a plurality of blades along the circumference equipartition, and the sharp edge is pegged graft in the socket, and the blade carries out axial fixity to two apron from two apron peripheries for the inside hookup fastness of this kind of split type impeller self is good, and light in weight, thereby can effectively save work energy consumption, and the preparation is convenient, and the cost is low.

The blades on the water pump impeller are straight-plate type and are arranged in the radial direction of the impeller body. The reason why the impeller of the water pump generates large noise in the working process is that when the water pump works, the water flow state in the impeller cavity is unstable, relatively high noise is generated under the surging of the blades, and the water pump is not suitable for being applied to places with high requirements on noise.

SUMMERY OF THE UTILITY MODEL

The technical problems to be solved by the utility model are as follows: the impeller structure of the vortex pump is provided, and noise generated in the working process of the impeller structure is low.

The technical scheme for solving the technical problem is as follows: the impeller structure of the vortex pump comprises a disc-shaped impeller body, wherein a plurality of blades are uniformly distributed on the impeller body along the circumferential direction of the impeller body, the blades protrude to the outer side of the axial end face of the impeller body, and a shaft hole for the insertion connection of a wheel shaft is formed in the middle of the impeller body.

The impeller structure of the vortex pump is arranged in a shell of the water pump and rotates to push water flow to enable the water pump to discharge water when in work. The vanes can be formed by milling and connected with the impeller body into a whole, or can be connected with the impeller body by welding. During the rotation of the impeller body, the blades push water to pump water out.

Further, an arc-shaped transition is formed between the inner end and the outer end of the bent part.

Further, the inner end sides of the blades are straight pieces, the inner end sides of the blades are arranged in the radial direction of the impeller body, a deflection angle generated by the bent portion in the circumferential direction of the impeller body is a, and a ranges from 8 degrees to 11 degrees.

Further, a is 10 degrees.

Further, the outer edge of the impeller body is a sharp part, and the thickness of the sharp part is gradually reduced from inside to outside.

Further, the blades are sleeved on the impeller body from the outer edge of the impeller body and are welded and fixed on the impeller body.

Compared with the prior art, the utility model has the advantages that: this impeller structure is at the internal rotation of pump body and when promoting rivers and flow, and the curved part on the blade can provide certain transitional action for rivers, and the blade is comparatively gentle to the promotion of water, can not produce comparatively violent the swashing to rivers, can adapt to the fluid flow in the pump body well to can effectively reduce the produced noise of water pump in the course of the work.

Detailed Description

The utility model will be further explained with reference to the drawings.

The structure of the vortex pump comprises a pump body, wherein an impeller cavity is arranged in the pump body and is communicated with a water inlet and a water outlet which are separated from each other.

This impeller structure includes the impeller body 1 of disc, has a plurality of blades 3 along its circumference equipartition on impeller body 1, and these blades 3 are located the footpath of impeller body 1. The blades 3 protrude to the outside of the axial end face of the impeller body 1 to push water to flow when the impeller body 1 rotates. The middle part of the impeller body 1 is provided with a shaft hole 2 for the insertion connection of a wheel shaft, and the wheel shaft extends out of the outer side of the pump body and is used for transmission connection with a motor. In the radial direction of the impeller body 1, the outer end sides of the blades 3 are formed with curved portions having arc-shaped transitions between the inner ends and the outer ends thereof.
