[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] For an example, please refer to... Figure 1 , 23, 4, and 5, a water pump for a pump, comprising a pump body 1 and an impeller structure disposed inside the pump body 1. The front end of the pump body 1 is provided with a docking end, which is fitted with a sealing component. The rear end of the pump body 1 is provided with an inlet 7, a bypass port, and an outlet 8 from top to bottom. An inlet pipe assembly is provided between the inlet 7 and the impeller structure. The impeller structure is disposed inside the front end of the inlet pipe assembly. The impeller assembly is fitted with a driving component. A flow guiding assembly is provided inside the pump body 1 and is disposed outside the inlet pipe assembly. A bypass component 20 is fitted to the rear end of the pump body 1. The bypass component 20 connects the bypass port and the outlet 8. A bypass pipe 19 is fixedly connected to one side of the upper end of the bypass component 20. The bypass pipe 19 passes through the inlet pipe assembly and extends into its interior.

[0028] The pump body 1 is cylindrical in shape, with a simple structure and easy manufacturing. The front end is connected to the sealing component, which can improve the overall sealing performance when connected to the drive component. The sealing component is detachable, which can facilitate disassembly, inspection, cleaning and other maintenance of its internal parts in the future, thereby reducing maintenance costs.

[0029] The impeller assembly is connected to the drive unit. The rotation of the impeller assembly creates a negative pressure at the inlet 7, which draws in liquid. The drawn-in liquid is input into the pump body 1 through the inlet pipe assembly and discharged through the outlet 8. The bypass component 20 is provided so that when the pump operating flow rate is lower than the design minimum flow rate, the bypass pipe 19 can return part of the medium to the inlet pipe assembly, avoiding overheating of the pump body due to insufficient flow.

[0030] Please refer to Figure 1 , 2 3, 4, and 5, the water inlet pipe assembly includes a liquid inlet pipe b22 that mates with the inner side of the water inlet 7, and a liquid inlet pipe a9 that mates with one side of the liquid inlet pipe b22. The front end of the liquid inlet pipe a9 has a mating interface, which mates with an annular pipe. An impeller structure is set inside the annular pipe. The annular pipe includes a housing a11 and a housing b15 that mate with each other. The rear end of the housing b15 has a liquid inlet 13 that mates with the mating interface at the front end of the liquid inlet pipe a9. The sides of the housing b15 and the housing a11 have several liquid outlets 14. The middle part of the housing a11 has an installation part for the impeller structure. The impeller structure includes an impeller 12, and the front end of the impeller 12 is fixedly connected to a mating end 16. The middle part of the mating end 16 has a mounting hole that mates with the output end of the drive component.

[0031] The water inlet pipe assembly uses inlet pipes a9 and b22, housing a11 and housing b15 that fit together. Housing b15 fits together with inlet pipe a9. It adopts a modular design, which allows the whole assembly to be easily disassembled during maintenance, so as to clean and repair the pump body and reduce subsequent maintenance costs.

[0032] Please refer to Figure 1 , 2 3, 4 and 5, the flow guiding assembly includes a connecting ring 10, and a plurality of flow guiding blades 17 are fixedly connected at equal intervals inside the connecting ring 10.

[0033] The arrangement of multiple guide vanes 17 can effectively disperse the water flow and reduce the fluid pressure borne by a single vane, thereby reducing the generation of eddies. The cross-section of the guide vane 17 is conical, so that the cross-sectional area of ​​the vane at different positions can adapt to the changes in water flow velocity and maintain water flow stability.

[0034] The pump body 1 has several protrusions inside for mounting the connecting ring 10, which are fixed by screws.

[0035] The front end face of the mating end has a mating groove. The sealing assembly includes a sealing element 2 disposed in the mating groove. A mating protrusion 3 is disposed in the middle of the sealing element 2, and a bearing 4 is installed on the inner side of the mating protrusion 3. A sealing ring a5 and a sealing ring b6 are fixedly connected to the front end face of the sealing element 2 respectively. A valve mating end 21 is disposed at the upper end of the pump body 1. The valve mating end 21 is hollow inside and communicates with the inside of the pump body 1.

[0036] The sealing components are fitted inside the mating groove. The mating protrusion 3 in the middle of the seal 2 is used to mate with the drive output shaft. The sealing ring a5 and the sealing ring b6 form a double seal to ensure the sealing effect.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
