Specific implementation mode
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
It is the structural schematic diagram before the utility model pulsed sewage lifting pump startup such as Fig. 1；The utility model discloses
A kind of pulsed sewage pump includes stretching out cesspool 1 in 1 liquid level of the cesspool pump housing 2 below and top for being arranged
Riser 6 is provided with the atmosphere chamber 4 of bottom opening in the pump housing 2, is sleeved on atmosphere chamber 4 and open-topped small air cavity 5,
The small air cavity 5 is connected to by open top with atmosphere chamber 4, and 2 top of the pump housing is provided with to be connected to atmosphere chamber and small air cavity
Air inlet pipe 7, the riser 6 is sleeved in atmosphere chamber 4 and small air cavity 5 simultaneously, and small air cavity is extended in 6 bottom of the riser
There is water sucking mouth 9 in setting, the air admission hole for being connected to small air cavity 7 is provided on the tube wall that the riser 6 is located in small air cavity 7
8。
For the present embodiment by being equipped with small one and large one two air cavitys in the pump housing, two air cavitys are closed by open at one end one end
Tubular article forms, and one is just set, and an inversion, small air cavity is placed in atmosphere chamber, and riser passes through among two air cavitys, is carrying
Air admission hole is arranged close to stingy intracavitary in riser, and using continuous gas entry, interval forms bubble, increases soil pick-up ability, hoisting power
And less than 80% time work of rate can be flooded in stingy flow, working limit increases use scope for 25%.
As Figure 2-Figure 5, the pump housing 1 is liquid entirely inside two air cavitys of size and riser before unaerated, with
Gas is filled with, and the water in atmosphere chamber is discharged from lower end water inlet 2, and the liquid of stingy intracavitary is from beside its bottom
Aperture is discharged into riser, and when stingy intracavitary liquid level drops to this aperture, the pressure of stingy intracavitary is equal to liquid at aperture
Pressure caused by gravity；Continue to inflate, pressure will increase in air cavity, be more than the pressure of liquid gravity at aperture, such gas
Riser will be entered from aperture, separate the liquid in riser, form bubble, with continuing to inflate, which is gradually expanded,
Liquid rising is push, until outside discharge pipe；It is discharged riser in a flash in liquid, is in aperture above section in riser
Atmospheric pressure, pressure difference is pressure caused by liquid at aperture, which will push sludge and carry from promoting bottom of the tube and enter
