Intake antrum connects.
Further, the inlet and outlet are setting up and down, and the intake antrum is set as arc-shaped cavity.
Further, the arc-shaped cavity bottom is provided with the water sucking mouth being correspondingly arranged with water outlet.
Further, the water sucking mouth aperture is more than water outlet aperture, and its face be overlapped in the vertical direction with water outlet
Product is set as 3/4~7/8.
The beneficial effects of the utility model are：
The utility model vacuum self-priming apparatus makes the Pump Suction mouth of a river by the way that closed self-sucking pot is connected on before pump on suction hose
Positive pressure water suction is become from negative pressure water suction；After starting mode of pump, water level is gradually reduced in tank, and tank inner air pressure is made to continuously decrease and shape
Into negative pressure, liquid is then gradually increasing by suction hose, until suction hose is liquid filled completely, then this water system just into
Operating condition is entered, the air in tank is taken to outside tank by water with the continuity of run time, and reach normal fortune in the form of bubbles
Turn state.

Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
It is the scheme of installation of the utility model vacuum self-priming apparatus as shown in Figure 1；It is true to be illustrated in figure 2 the utility model
The front view of empty self-priming apparatus；It is illustrated in figure 3 the side view of the utility model vacuum self-priming apparatus；The utility model is a kind of true
Empty self-priming apparatus, including being used for the self-sucking pot 1 mounted on 4 front end of water pump, 1 inside of self-sucking pot forms water storage cavity 8；It is described from
1 side wall upper part of cucurbitula is provided with the water inlet 9 for being connected with inlet channel 2, and 1 lower sidewall of self-sucking pot, which is provided with, to be used for
The water outlet 10 connected with outlet conduit 3,1 top of self-sucking pot are provided with the fill hole 5 connected with water storage cavity and gas vent
6, the Level meter 7 for sensed water level control moisturizing and exhaust is provided in the water storage cavity 1.
1 water inlet 9 of the present embodiment self-sucking pot is connected with inlet channel 2, and water outlet 10 is connected with 4 water inlet of water pump,
