[0022] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0023] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0024] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a novel rotary suction jet drag reduction pump, including a pump body 1, which has a water inlet 11 and a water outlet 12. A rotary suction device 2 is provided at the water inlet 11 to improve the suction performance of the pump and reduce the energy loss of the fluid during the suction process, thereby achieving a high-efficiency, low-energy-consumption working state; a flow stabilizing device 3 is provided at the water outlet 12 to reduce the energy loss of the fluid, reduce the backflow and vortex of the fluid between the impeller and the pump casing, and improve the working efficiency and operation stability of the pump.

[0026] The swirl suction jet drag reduction pump of this embodiment is a centrifugal pump. In practice, the swirl suction device 2 and the flow stabilizing device 3 can also be applied to the water inlet and outlet of other types of water pumps to improve the performance of the water pump, and are not limited to centrifugal pumps.

[0027] Specifically, the above-mentioned rotary suction device 2 includes a mounting frame 21 detachably connected to the end of the pump body 1 and a wheel portion 22 detachably connected to the mounting frame 21. A water outlet is provided on the mounting frame 21 along its axial direction. The inner periphery of the water outlet is connected to a connecting portion 212 through six support rods 211. A water guide port 213 is formed between two adjacent support rods 211, and a mounting hole is provided in the middle of the above-mentioned connecting portion 212.

[0028] The wheel portion 22 includes a fixed shaft 221 coaxially connected to the mounting frame 21, and six twisting blades 222 are evenly distributed on the outer circumference of the fixed shaft 221. The twisting blades 222 are spiral-shaped, and a rotation suction channel is formed between two adjacent twisting blades 222. The rotation suction channel is connected to the water guide port 213 in a one-to-one correspondence, that is, the fluid enters the corresponding rotation suction channel from the water guide port 213 and rotates into the interior of the pump body 1.

[0029] The fixed shaft 221 has a mounting portion 2211, and the mounting portion 2211 is connected to the mounting hole of the connecting portion 212 in a rotation-proof manner. For example, the outer periphery of the mounting portion 2211 and the inner periphery of the mounting hole are provided with planes that match each other.

[0030] In this embodiment, the wheel portion 22 and the mounting frame 21 are connected by a screw 23 , and the screw 23 is threadedly connected to a threaded hole on the mounting portion 2211 , and the screw head of the screw 23 abuts against the end of the connecting portion 212 .

[0031] In addition, the mounting frame 21 also has a sleeve 214 adapted to the inner periphery of the water inlet 11, the sleeve 214 is located at the outer periphery of the wheel portion 22, and there is a gap between the inner wall of the sleeve 214 and the outer edge of the twisted blade 222. Further, in the axial direction of the water inlet 11, the length of the wheel portion 22 is greater than the length of the sleeve 214.

[0032] By providing the above-mentioned swirling suction device 2, when the water pump is running, the water flow at the water inlet 11 will form a vortex. Through the swirling suction effect, the water flow rotates at the water inlet 11 of the pump to form a low-pressure area, thereby making it easier to suck the liquid into the pump, reducing cavitation and improving the self-priming ability of the water pump.

[0033] The above-mentioned flow stabilizing device 3 includes a through hole connected to the water outlet 12, and a partition 31 is arranged on the inner periphery of the through hole, and the partition 31 divides the through hole into two flow stabilizing channels 32. In addition, the above-mentioned flow stabilizing device 3 also includes six guide plates 33, and the six guide plates 33 are evenly distributed on the outer periphery of the through hole, and the guide plates 33 extend into the water outlet 12 and contact with the inner wall of the water outlet 12.

[0034] At the outlet of the water pump, the water flow will form vortices, which will cause energy loss and unstable water flow, affecting the efficiency of the water pump. However, by providing the flow stabilizing device 3 in this embodiment, these vortices can be broken, so that the water flow can flow out more smoothly and evenly, which helps to reduce energy loss, increase the head and flow rate of the water pump, and reduce the noise and vibration of operation.

[0035] It should be noted that the number of twisted blades 222 and the number of guide plates 33 and partition plates 31 in this embodiment can be reasonably designed according to actual conditions and are not limited to the specific numbers disclosed in this embodiment.

[0036] It should also be noted that the mounting frame 21 and the flow stabilizer 3 of this embodiment are connected to the pump body 1 by screws, and countersunk holes are provided on the mounting frame 21 and the flow stabilizer 3, and threaded holes are opened at both ends of the pump body 1. In addition, through holes are provided on the mounting frame 21 and the flow stabilizer 3, and the through holes are aligned with the original through holes on the pump body 1 for connecting to the pipeline to facilitate connection with the pipeline bolts.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
