Description

Blade and impeller assembly for centrifugal water pump

Technical Field

The utility model relates to a centrifugal water pump's blade and impeller subassembly.

Background

The centrifugal pump is designed according to the centrifugal force principle, and the motor drives the impeller blades rotating at high speed to drive water to rotate, so that the water is thrown out, and the purpose of conveying is achieved. The impeller and the blades of the centrifugal pump are important parts of the water pump, and the traditional blades are unreasonable in design, so that the purposes of low energy consumption and high efficiency are difficult to achieve.

Disclosure of Invention

An object of the utility model is to provide an efficient centrifugal water pump's of low energy consumption blade and impeller subassembly.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a centrifugal water pump's blade and impeller subassembly, includes blade and impeller, and the impeller is fixed on the blade, and the middle part of blade is equipped with installation annular step, is equipped with the mounting hole on the step, and the impeller also is equipped with the impeller hole, be equipped with the spiral water conservancy diversion groove and the spiral water conservancy diversion step of the same quantity on the blade, and the inboard of water conservancy diversion groove is equipped with the water conservancy diversion hole, the width from interior to exterior of water conservancy diversion groove and water conservancy diversion step enlarges gradually, and the side of impeller has many spiral water conservancy diversion strips.

Preferably, the diversion hole extends to the step edge.

Preferably, the inner side of the diversion step is provided with a notch, and the notch is connected with the diversion hole.

Preferably, the mounting hole is a kidney-shaped hole.

Preferably, the inner end part of the spiral guide strip of the impeller extends into the impeller hole.

After the structure is adopted, the utility model discloses a sub-assembly of impeller and blade rotates and produces centrifugal force. The blades are provided with a plurality of spiral diversion trenches and are matched with a plurality of spiral diversion strips of the impeller, so that low-energy-consumption and high-efficiency conveying is realized.

FIG. 2 is a perspective view of the blade of FIG. 1;

fig. 3 is a perspective view of the impeller of fig. 1.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.

Referring to fig. 1, 2 and 3, a blade and impeller assembly of a centrifugal water pump includes a blade 1 and an impeller 20, the impeller 20 is fixed on the blade 1, an installation annular step 11 is provided in the middle of the blade 1, an installation hole 12 is provided on the step 11, the impeller 20 is also provided with an impeller hole 21, the blade 1 is provided with spiral guide grooves 2 and spiral guide steps 3 of the same number, the inner side of the guide groove 2 is provided with guide holes 4, the widths of the guide groove 2 and the guide steps 3 are gradually enlarged from inside to outside, and the side of the impeller 20 is provided with a plurality of spiral guide strips 22.

Referring to fig. 2, the guiding holes 4 extend to the edge of the step 11. The diversion holes 4 can be enlarged, and the efficiency is improved.

Referring to fig. 2, a notch 31 is formed in the inner side of the flow guiding step 3, and the notch 31 is connected with the flow guiding hole 4. The water flow can flow into the diversion hole 4 through the diversion groove 2 without obstruction.

Referring to fig. 2, the mounting hole 12 is a kidney-shaped hole. Facilitating the mounting and positioning of the blade 1.

Referring to fig. 3, the inner end portion of the spiral guide strip 22 of the impeller 20 extends into the impeller hole 21. The installation and the location are convenient.

The utility model discloses when the installation, see that fig. 1 is shown, fix impeller 20 on blade 1 to install blade 1 on motor shaft 30, motor shaft 30 drives blade 1 and impeller 20 and rotates when rotating, and rivers dash the left side and pass through to the right side, and rivers stir earlier many spiral water conservancy diversion strips 22 through impeller 20 and form the swirl, and in the reinforcing through guiding gutter 2, flow to the right side in guiding hole 4 at last. Therefore the utility model discloses under the motor condition of same power, can produce higher efficiency.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
