[0028] The vacuum water diversion tank 3 is pre-filled with water at the same height as the connection between the vacuum water diversion tank 3 and the water suction pipe 2 and the self-sealing overflow pipe 9 to ensure that the self-priming pump 4 is filled with water. The vacuum water diversion tank 3 remains sealed, and the self-priming pump 4 is started. The water storage capacity in the vacuum water diversion tank 3 decreases rapidly, and the water level in the vacuum water diversion tank 3 drops sharply. After reaching a certain negative pressure, the water in the water suction pool 1 continuously enters the vacuum water diversion tank 3 along the water suction pipe 2 under the action of atmospheric pressure. At this time, the self-priming pump 4 operates normally and stably. When the discharge water volume of the self-priming pump 4 and the inflow water volume of the suction pipeline reach a balance, the liquid level in the vacuum water diversion tank 3 no longer drops and reaches a stable working state. At this time, the self-priming pump 4 also reaches the rated working state; after stopping the self-priming pump 4, the water in the drainage pipe 10 of the self-priming pump 4 flows back to the vacuum water diversion tank 3 to ensure the next use.

[0029] Embodiment 2 of the present utility model: A self-priming pump water tank water suction system, comprising:

[0030] The water absorption pool 1 is excavated underground or embedded in the ground;

[0031] A vacuum water diversion tank 3, wherein the vacuum water diversion tank 3 is connected to one end of a water suction pipe 2, and the other end of the water suction pipe 2 is placed at the bottom of the water suction pool 1. The connection between the vacuum water diversion tank 3 and the water suction pipe 2 is located at the upper part of the side wall of the vacuum water diversion tank 3, and the connection between the vacuum water diversion tank 3 and the water suction pipe 2 is the highest point of the water suction pipe 2;

[0035] When it is detected that the water level in the water absorption pool 1 reaches the starting liquid level, the water volume meets the conditions for starting the water pump. At this time, the water injection valve 6 is opened, and water is injected into the vacuum water diversion tank 3 through the water injection equipment, and then flows into the shell of the self-priming pump 4. As the water filling amount in the water diversion system increases, the gas accumulated in the self-priming pump suction pipe 8 and the vacuum water diversion tank 3 is gradually discharged from the overflow exhaust valve 5 on the upper part of the vacuum water diversion tank 3. When the water level rises to the height of the self-sealing overflow pipe 9 and the overflow of sewage and waste water from the self-sealing overflow weir of the self-priming pump 4 is stable, stop water injection, close the overflow exhaust valve 5, the water injection valve 6 and the water injection equipment, the vacuum water diversion tank 3 remains sealed, and the self-priming pump 4 is started.

At this time, the water injection valve 6 is opened, and water is injected into the vacuum water diversion tank 3 through the water injection equipment, and then flows into the shell of the self-priming pump 4. As the water filling amount in the water diversion system increases, the gas accumulated in the self-priming pump suction pipe 8 and the vacuum water diversion tank 3 is gradually discharged from the overflow exhaust valve 5 on the upper part of the vacuum water diversion tank 3. When the water level rises to the height of the self-sealing overflow pipe 9 and the overflow of sewage and waste water from the self-sealing overflow weir of the self-priming pump 4 is stable, stop water injection, close the overflow exhaust valve 5, the water injection valve 6 and the water injection equipment, the vacuum water diversion tank 3 remains sealed, the self-priming pump 4 is started, and the water storage volume in the vacuum water diversion tank 3 is rapidly reduced.
