Zusammenfassung:	The utility model discloses a vacuum water diversion device which comprises a vacuum box used for providing a closed cavity; the water suction pipe is communicated with the vacuum box and is used for sucking water at a low position into the vacuum box at a high position; the water outlet pipe is used for connecting the vacuum box and the water pump, and a water replenishing valve is mounted on a pipeline; and the exhaust valve is mounted at the top of the vacuum box and is used for exhausting air in the vacuum box. According to the vacuum priming device, a bottom valve arranged at the bottom of the water suction pipe of the water pump for priming before starting is removed, the working principle of the vacuum priming device is that when the water pump operates, water in the vacuum box is sucked firstly, and due to the fact that the water in the vacuum box is discharged in a short time, certain vacuum is formed in the vacuum box; and water in the water suction well enters the vacuum box body through the water
