[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", "vertical", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of this utility model, "first feature" or "second feature" may include one or more of these features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features being described. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of these features.

[0027] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] The following is a further detailed description of the self-circulating cooling water pump of the present invention in conjunction with the accompanying drawings.

[0029] Combined with attachment Figure 1-8 The specific implementation process of the self-circulating cooling water pump of the utility model is as follows:

[0030] A self-circulating cooling water pump comprises a bearing housing 1 and a pump body 2, connected by a main shaft 3. A water seal plate 4 is provided on one side of the pump body 2 and communicates with the bearing housing 1 to achieve water circulation. A turbine 5 is mounted within the pump body 2, mounted on the main shaft 3 and rotating with it to drive the water flow. A water inlet 6 is provided on one side of the pump body 2 for water to enter the pump body 2. A water outlet 7 is provided on the upper portion of the pump body 2 for connecting to a water pipe or other device for irrigation.

[0031] Furthermore, the water sealing plate 4 is provided with a first water circulation hole 8, and the bearing housing 1 is provided with a second water circulation hole 9. The first water circulation hole 8 and the second water circulation hole 9 are connected in a one-to-one correspondence, forming a circulating water path. In this way, cooling water can circulate between the water sealing plate 4 and the bearing housing 1, removing the heat generated by the bearing housing 1.

[0032] In terms of connection method, the water sealing plate 4 and the bearing box 1 can be detachably connected by bolts to facilitate maintenance and replacement; alternatively, the water sealing plate 4 and the bearing box 1 can also be integrally formed to improve the integrity and stability of the structure.

[0033] In order to drive the main shaft 3 to rotate, a power input end of the main shaft 3 is provided with a pulley 10 sleeved on the outside thereof, and the pulley 10 is connected to an external driving device, such as a motor.

[0034] To further improve the cooling effect, the present invention further includes a first cooling water pipe 11 and a second cooling water pipe 12. The first cooling water pipe 11 connects the water inlet 6 and the bearing housing 1 to introduce cooling water into the bearing housing 1; the second cooling water pipe 12 connects the bearing housing 1 and the water outlet 7 to discharge the water after cooling the bearing housing 1.

[0035] In addition, a support leg 13 is provided at the bottom of the pump body 2 for supporting the entire pump body 2 to ensure its stable operation.

[0036] The above description of the present invention and its embodiments is non-limiting.
