[0035] Working principle: When the idling-resistant water pump of the fully self-circulating cooling system is used, when the idling-resistant water pump starts to run, the internal coolant in the external water tank 10 enters the interior of the stationary ring seat 8 through the water inlet 84 in a drop manner, soaks the stationary ring 6, and then passes through the stationary ring through-channel 61 to enter the cooling groove 34 of the rotating ring 3. When the rotating ring 3 rotates, it will drive the coolant in the cooling groove 34 to rotate. When the rotating coolant collides with the stationary ring water outlet return baffle 63 on the stationary ring 6, pressurized coolant is generated and enters the stationary ring water outlet return hole 64. Due to the push of pressure, it is pressed into the water tank 10 through the water outlet 81, thus forming a circulation. At the same time, during the operation of the idling resistant water pump, since a water tank 10 is added to the outside of the water pump, the high-temperature fluid generated inside the water pump's shaft seal due to idling can be sent into the liquid tank for cooling and then flow into the shaft seal for circulation cooling. In this way, the rotating ring 3 and the static ring 6 can be cooled. Its main function is to rely on its own structure to allow the liquid inside the static ring 6 and the rotating ring 3 to circulate completely with the cooling tank, so that the water pump can achieve the purpose of long-term idling without damage, making it more resistant to idling, greatly improving the service life of the water pump, and the overall structure is simple and practical.

The problem solved by the present invention is that most of the existing water pumps on the market can only cool the rotating ring 3 and static ring 6 inside them, because there is no The method can circulate the liquid in the rotating ring 3 and the static ring 6, so when the water reaches a certain temperature, the water pump will still be damaged. The existing technology can only slightly extend the service life, but cannot completely idle, and cannot improve the protection performance of the water pump. There are certain limitations when using it.
