[0035] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0036] Please refer to Figure 1 to Figure 2The utility model provides a silent cooling water pump, comprising a pump casing 1, an impeller 5, a water pump shaft 7, a motor 3, a reducer 2, a cooling channel 9, a first bearing 6 and a second bearing 4;

[0037] A volute cavity 8 is provided in the head of the pump housing 1;

[0038] The impeller 5 is arranged in the volute cavity 8;

[0039] The water pump shaft 7 is connected to the impeller 5, one end of the head of the water pump shaft 7 is connected to the first bearing 6, and one end of the tail of the water pump shaft 7 is connected to the reducer 2 and the motor 3 in sequence;

[0040] The first bearing 6 is arranged on the inner wall of the volute cavity 8;

[0041] The second bearing 4 is sleeved on the water pump shaft 7 and is located between the impeller 5 and the reducer 2;

[0042] The cooling channel 9 is communicated with the volute cavity 8 and surrounds the second bearing 4;

[0043] In this embodiment, a water inlet 12 and a water outlet 13 are provided on the volute cavity 8;

[0044] When in use, external water flows into the volute cavity 8 through the water inlet 12, the motor 3 drives the water pump shaft 7 to rotate through the reducer 2, and drives the water to flow out from the water outlet 13 through the impeller 5. The first bearing 6 and the second bearing 4 are installed on the water pump shaft 7. The two bearings support each other and can evenly share the force, reduce the load of a single bearing, and thus reduce the heat generated by the bearing. The heat generated by the first bearing 6 can be cooled by the water in the volute cavity 8, and the heat generated by the second bearing 4 can be cooled by the water in the cooling channel 9. The heat is carried out of the water outlet 13 of the volute cavity 8 by the continuous flow of water.

[0045] In this embodiment, the longitudinal section of the cooling channel 9 is an annular structure.

[0046] In this embodiment, it also includes a base 10 and a rubber pad 11. The base 10 is fixedly arranged at the bottom of the pump housing 1, and the rubber pad 11 is installed at the bottom of the base 10. The rubber pad 11 and the base 10 can effectively absorb the vibration generated by the water pump motor 3, thereby effectively ensuring the silent operation of the water pump.

[0047] The working principle of the utility model is as follows:

[0048] External water flows into the volute cavity 8 through the water inlet 12, and the motor 3 drives the water pump shaft 7 to rotate through the reducer 2, and drives the water to flow out from the water outlet 13 through the impeller 5. The first bearing 6 and the second bearing 4 are installed on the water pump shaft 7. The two bearings support each other and can evenly distribute the force, reduce the load of a single bearing, and thus reduce the heat generated by the bearing. The heat generated by the first bearing 6 can be cooled by the water in the volute cavity 8, and the heat generated by the second bearing 4 can be cooled by the water in the cooling channel 9. The heat is carried out of the volute cavity 8 through the continuous flow of water and flows out of the water outlet 13.

[0049] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
