For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The self-circulating cooling water pump of the present invention is further described in detail below in conjunction with the accompanying drawings.

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

[0030] A self-circulating cooling water pump comprises a bearing box 1 and a pump body 2, which are connected by a main shaft 3. A water sealing plate 4 is provided on one side of the pump body 2, and the water sealing plate 4 is connected to the bearing box 1 to realize the circulation of water flow. A turbine 5 is provided inside the pump body 2, which is sleeved on the main shaft 3 and rotates with it, and is used to drive the water flow. A water inlet 6 is provided on one side of the pump body 2 for water source to enter the pump body 2; a water outlet 7 is provided on the upper part of the pump body 2 for connecting a water pipe and other devices for irrigation.

[0031] Furthermore, the water sealing plate 4 is provided with a first water circulation hole 8, and the bearing box 1 is provided with a second water circulation hole 9, and the first water circulation hole 8 and the second water circulation hole 9 are connected one by one to form a circulating water path. In this way, cooling water can circulate between the water sealing plate 4 and the bearing box 1 to take away the heat generated by the bearing box 1.
