Description

Technical Field

[0001] The present disclosure relates to the technical field of high-speed water pumps, and in particular to a pump impeller structure of a high-speed water pump. Background Art

[0002] CN220815874U discloses a water pump turbine runner with a bionic blade inlet edge type. Since each blade is close to the shaft sleeve, the liquid that can be centrifuged by each blade (that is, the blade transports water to the volute through centrifugal force) is prone to collide with the pump casing. Therefore, cavitation is prone to occur when the flow rate of the high-speed water pump is large, and it is not suitable for high-speed water pumps with large flow rates.

[0003] Therefore, the existing technology needs to be improved.

[0004] Public content

[0005] In response to the defects of the existing technology, the present disclosure provides an impeller structure of a high-speed water pump, which aims to solve the technical problem in the related technology that each blade of the impeller is close to the shaft sleeve, resulting in the liquid that can be centrifuged by each blade easily colliding with the pump casing, so cavitation is easily caused when the flow rate of the high-speed water pump is large, and thus the impeller is not suitable for high-speed water pumps with larger flow rates.

[0006] The technical solutions adopted by the present disclosure to solve the above technical problems are as follows:

[0007] The present disclosure provides a pump impeller structure of a high-speed water pump, comprising:

[0008] A first shell and a second shell arranged opposite to each other;

[0009] a shaft sleeve, passing through the first shell and the second shell;

[0010] Centrifugal blades are spirally arrayed around the sleeve and fixed between the first shell and the second shell; and

[0011] The inducing vanes are fixed to one end of the shaft sleeve in a spiral array and are located outside the first shell and the second shell.

[0012] In some embodiments, any two adjacent centrifugal blades, the outer surface of the first shell, and the outer surface of the second shell form a water outlet, and the water outlet is connected to the volute.

[0013] In some embodiments, the inducing blade is integrally formed with the shaft sleeve.

[0014] In some embodiments, the number of the inducing blades is 3.

[0015] In some embodiments, the centrifugal blades, the first shell, and the second shell are integrally formed.

[0016] In some embodiments, the inducing blade, the shaft sleeve, the centrifugal blade, the first shell, and the second shell are integrally formed.

[0017] Beneficial Effects: The present invention uniformly adjusts the flow rate of the liquid by additionally providing induction blades, and arranging the induction blades to be fixed in a spiral array at one end of the shaft sleeve and located outside the first and second shells, thereby effectively reducing the collision between the liquid that can be centrifuged by each centrifugal blade and the first shell and / or the second shell, thereby effectively avoiding the occurrence of cavitation when the flow rate of the high-speed water pump is large, and is suitable for high-speed water pumps with large flow rates. Therefore, the present invention solves the technical problem in the related art that the impeller is not suitable for high-speed water pumps with large flow rates because each blade of the impeller is close to the shaft sleeve, resulting in the liquid that can be centrifuged by each blade easily colliding with the pump casing, so cavitation is easily caused when the flow rate of the high-speed water pump is large.

It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it may be directly connected or coupled to the other element, or there may be intermediate elements. In addition, "connected" or "coupled" as used herein may include wireless connections or wireless couplings. The term "and / or" used herein includes all or any one of the units and all combinations of one or more associated listed items.

[0024] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art in the art to which this disclosure belongs. It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and, unless specifically defined as herein, will not be interpreted in an idealized or overly formal sense.

[0025] See also Figure 1 and Figure 2 The present disclosure provides a high-speed water pump impeller structure, comprising: a first shell 11 and a second shell 12 arranged opposite to each other (the first shell and the second shell can be set as but not limited to the following Figure 1 The centrifugal blades 30 and the inducing blades 40 are basically disc-shaped as shown.

[0026] The shaft sleeve 20 passes through the first shell 11 and the second shell 12. In some embodiments, the first shell is provided with a first through hole (not shown in the figure), and the second shell is provided with a second through hole (not shown in the figure). The shaft sleeve 20 includes a first end 21 located in the first through hole and a second end 22 located in the second through hole. The second end 22 extends out of the second shell 12 from the opening of the second through hole away from the first shell 11. The first end and the inner surface of the first through hole are integrally formed without a gap to fix the shaft sleeve and the first shell. The second end and the inner surface of the second through hole do not contact (that is, there is a gap between the second end of the shaft sleeve and the second through hole, and the liquid enters between the first shell and the second shell through the gap). The first end and the second end of the shaft sleeve are both used to connect with the rotating shaft of the high-speed water pump (not shown in the figure, please refer to the prior art, which is not described here).

[0027] The centrifugal blades 30 are arranged in a spiral array around the sleeve 20; that is, there can be more than one centrifugal blade, with more than one centrifugal blade arranged in a spiral array around the sleeve. The centrifugal blades 30 are fixed between the first housing 11 and the second housing 12. In some embodiments, the first and second housings do not contact each other, so that a gap exists between the side surfaces of the first and second housings. One end of each centrifugal blade is located in this gap and is integrally formed with the first and second housings on both sides, thereby securing the first and second housings, as well as each centrifugal blade.

[0028] The induction blades 40 are fixed in a spiral array to one end of the sleeve 20 (i.e., the second end 22); that is, the number of induction blades can be more than one, and the more than one induction blades are arranged in a spiral array around the sleeve, and each induction blade is fixed in a spiral shape (for example, integrally formed) to the outer surface of the sleeve, so that the flow rate of the liquid can be uniformly adjusted by the rotation of the induction blades. The induction blades 40 are located outside the first shell and the second shell; that is, any point of the induction blades is located outside the second shell and the first shell. In some embodiments, please refer to Figure 1 The number of induction blades is 3, and the 3 induction blades are integrally formed with the shaft sleeve, so that the flow rate of the liquid can be further evenly adjusted through the rotation of the 3 induction blades.

[0029] In some embodiments, see Figure 1 Any two adjacent centrifugal blades, the outer surface of the first shell, and the outer surface of the second shell form a water outlet 50, and the water outlet is connected to an additional volute (not shown in the figure, please refer to the prior art, which is not described here). When the high-speed water pump is working, the rotation of the induction blades evenly adjusts the flow rate of the liquid, and then the liquid enters between the second shell and the first shell from the second through hole, and after being centrifuged by the centrifugal blades, enters the volute from the water outlet; in this process, since the flow rate of the liquid is evenly adjusted before entering between the first shell and the second shell, the collision between the liquid that can be centrifuged by each centrifugal blade and the first shell and / or the second shell is effectively reduced, thereby effectively avoiding the occurrence of cavitation when the flow rate of the high-speed water pump is large, and is suitable for high-speed water pumps with large flow rates.

[0030] The impeller structure of the high-speed water pump provided by the present disclosure adjusts the flow rate of the liquid uniformly by additionally providing induction blades, and setting the induction blades to be spirally arrayed and fixed to one end of the shaft sleeve and located outside the first shell and the second shell, thereby effectively reducing the collision between the liquid that can be centrifuged by each centrifugal blade and the first shell and / or the second shell, thereby effectively avoiding the occurrence of cavitation when the flow rate of the high-speed water pump is large, and is suitable for high-speed water pumps with large flow rates. Therefore, the present disclosure solves the technical problem that the impeller in the related art is not suitable for high-speed water pumps with large flow rates because each blade of the impeller is close to the shaft sleeve, resulting in the liquid that can be centrifuged by each blade easily colliding with the pump shell, so cavitation is easily caused when the flow rate of the high-speed water pump is large.
