That is, a vacuum pump is performed by discharging the air in the pump chamber 3 to make the vacuum state and filling the fluid including water.

Accordingly. It is possible to improve the working efficiency of the pump because it is not necessary to perform a separate operation to initially fill the water in the pump chamber (3).

The air discharge device 10 according to the present embodiment is connected to the inlet 11 and the inlet of the pump chamber 3, the fluid flows into the pump chamber 3 to the fluid introduced into the inlet 11 An air discharge chamber 13 having a supply port 12 for supplying and a vacuum means 14 spatially connected to the air discharge chamber 13 to discharge air from the air discharge chamber 13 to the outside; It is made to include.

That is, the air is discharged from the air discharge chamber 13 and the pump chamber 3 to the outside through the vacuum means 14 and the fluid is introduced from the outside through the inlet 11.

As such, the fluid introduced through the inlet 11 is accommodated in the air discharge chamber 13 and supplied to the pump chamber 3 to fill the interior of the pump chamber 3. The air flowing into the air discharge chamber 13 together with the fluid is discharged to the outside through the vacuum means 14.

On the other hand, the air discharge pipe 15 connected to the vacuum means 14 is connected to a position higher than the inlet 11 in the air discharge chamber (13).

Accordingly, when the vacuum suction input by the vacuum means 14 is formed in the air discharge chamber 13, the fluid flowing into the inlet 11 freely falls and is stored in the air discharge chamber 13. In addition, the air supplied to the pump chamber 3 and introduced into the inlet 11 is discharged to the outside via the vacuum means 14 through the air discharge pipe 15.

At this time, the air remaining in the pump chamber (3) is discharged to the outside through the air discharge pipe (15) via the air discharge chamber (13).

In the inlet 11 is located at a position higher than the maximum height of the pump chamber (3).
