[0046] Example 1

[0047] The following is combined with Figure 1 and Figure 2 As shown, a water pump provided in this application is described in detail.

[0048] This application provides a water pump, which includes a housing 1, a liquid-sealing sleeve 2, an impeller assembly 3, and a rotor assembly.

[0049] Specifically, the housing 1 includes an upper shell and a lower shell. The upper shell and the lower shell are fastened together and surround an installation space 5. A liquid-separating sleeve 2 is disposed in the installation space 5, and the liquid-separating sleeve 2 divides the installation space 5 into a dry area 6 and a wet area 7. The dry area 6 and the wet area 7 are not connected, and liquid flows in the wet area 7.

[0050] Specifically, both the impeller assembly 3 and the rotor assembly are located in the wet area 7, and the impeller assembly 3 is fitted onto the rotor assembly. The impeller assembly 3 is able to rotate around the rotor assembly.

[0051] Specifically, the impeller assembly 3 has a sleeve portion, a rotating portion, and an impeller 15 portion; the impeller 15 portion is disposed above the rotating portion, and the rotating portion is sleeved on the rotor assembly through the sleeve portion; that is, the impeller 15 portion, the rotating portion, and the sleeve portion can rotate around the rotor assembly; the rotating impeller 15 portion can circulate the liquid in the wet area 7.

[0052] Specifically, a thrust ring 8 is provided on the rotor assembly and above the sleeve portion. When the impeller assembly 3 rotates around the rotor assembly, there may be a problem of the impeller assembly 3 moving along the axis of the rotor assembly. Therefore, a thrust ring 8 is provided on the rotor assembly and above the sleeve portion to limit the impeller assembly 3 and prevent it from moving along the axis of the rotor assembly.

[0053] Specifically, after a prolonged period of operation or shutdown, factors such as temperature differences can cause crystals or precipitates to form on the contact surface between the thrust ring 8 and the sleeve. These crystals or precipitates can affect the normal operation of the pump. Therefore, this application provides a through hole 9 on the rotating part. One end of the through hole 9 connects to the wet area 7, and the other end faces the contact surface between the sleeve and the thrust ring 8. When the impeller 15 rotates, the liquid in the wet area 7 can flow through this through hole to the contact surface between the sleeve and the thrust ring 8. This liquid can flush the contact surface, causing the crystals or precipitates to detach from the contact surface, thereby preventing the sleeve from getting stuck in the rotor assembly and allowing the pump to operate normally.

[0054] In summary, this application cleverly incorporates a through hole 9 in the sleeve portion, allowing liquid in the wet area 7 to flow through this hole to the contact surface formed between the sleeve portion and the thrust ring 8. This liquid flushes the contact surface, causing crystals or precipitates to detach and prevent their deposition, which could lead to blockage or jamming of the sleeve portion within the rotor assembly, thus ensuring normal operation of the water pump. Furthermore, flushing the contact surface with this liquid effectively removes heat generated by friction, reducing wear on components caused by friction.

[0055] In this embodiment, multiple through holes 9 are provided, and the multiple through holes 9 are arranged at intervals along the circumferential direction of the rotating part.

[0056] Specifically, there are three through holes 9, which are arranged at intervals along the circumference of the rotating part.

[0057] In summary, during the operation of the impeller assembly 3, the liquid circulates due to the water pressure inside the vortex channel (impeller assembly 3). As the three through holes 9 rotate with the impeller assembly 3, the starting end will pass through the high-pressure zone, thus forming a circulation. The end of the circulation points to the contact surface between the sleeve and the thrust ring 8, thereby flushing the crystals and precipitates and preventing the water pump rotor assembly from jamming.

[0058] In this embodiment, combined with Figure 2 As shown, the rotor assembly includes a rotor shaft 10, which extends along the axial direction of the housing 1 and is fixedly connected to the liquid-separating sleeve 2 at the center of the housing 1; that is, the rotor shaft 10 does not rotate and is fixed to the liquid-separating sleeve 2.

[0059] Preferably, the liquid-separating sleeve 2 is integrally formed with the rotor shaft 10.

[0060] Alternatively, the liquid-separating sleeve 2 is welded to the rotor shaft 10.

[0061] In this embodiment, combined with Figure 1 and Figure 2 As shown, the water pump also includes an inlet pipe 11 and an outlet pipe 12, both of which are connected to the wet area 7.

[0062] Specifically, the inlet pipe 11 is used to introduce liquid into the wet area 7, and the introduced liquid can be discharged from the outlet pipe 12 by the rotation of the impeller assembly 3.

[0063] Furthermore, the liquid mentioned above preferably refers to a coolant.

[0064] In this embodiment, combined with Figure 2 As shown, the sleeve part is the bushing 13, the rotating part is the rotating sleeve 14, and the impeller 15 part is the impeller 15.

[0065] Specifically, the rotating sleeve 14 is sleeved on the rotor shaft 10 via the bushing 13; the impeller 15 is disposed above the rotating sleeve 14;

[0066] The bushing 13, the rotating sleeve 14 and the impeller 15 can rotate around the rotor shaft 10, so that the impeller 15 can discharge the liquid in the wet area 7 through the liquid outlet pipe 12.

[0067] In this embodiment, combined with Figure 3 As shown, there is a first gap 16 between the impeller 15 and the liquid-separating sleeve 2, a second gap 17 between the rotating sleeve 14 and the liquid-separating sleeve 2, and a third gap 18 between the shaft sleeve 13 and the rotor shaft 10.

[0068] Specifically, the liquid introduced through the inlet pipe 11 can pass through the first gap 16, the second gap 17 and the third gap 18 in sequence and be discharged from the outlet pipe 12.

[0069] In summary, the liquid flows through the inlet pipe 11, the first gap 16, the second gap 17, and the third gap 18, and exits through the outlet pipe 12, forming a small loop. Additionally, the liquid flows through the inlet pipe 11, the first gap 16, the through hole 9, and the contact surface, exiting through the outlet pipe 12, forming another small loop. Therefore, the system splits into two loops after the first gap 16.

[0070] In this embodiment, combined with Figure 2 As shown, the water pump also includes a stator assembly 19. The stator assembly 19 is located in the dry area 6 and is fitted into the liquid-blocking sleeve 2.

[0071] Specifically, the stator assembly 19 can drive the impeller assembly 3 to rotate around the rotor shaft 10 by electromagnetism. The principle and structure of the stator assembly 19 driving the impeller assembly 3 to rotate around the rotor shaft 10 by electromagnetism is existing technology and can be understood by those skilled in the art, so it will not be described in detail, but only briefly as follows: The stator assembly 19 includes a coil 20 and a support frame 21; the support frame 21 supports the coil 20, so that the coil 20 is wound around the liquid-blocking sleeve 2.

[0072] Example 2

[0073] This application also provides a water pump, including the water pump described above. Therefore, it possesses all the beneficial effects of a water pump, which will not be specifically elaborated here.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
