Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The utility model discloses must use the immersible pump, its principle as follows: if the submersible pump is not used and the water pump is adopted, water cannot be normally sucked due to air entering the water inlet pipe.

The air inlet pipe is divided into an upper end and a lower end, the upper end of the air inlet pipe is above the water surface, and the air inlet pipe is communicated with the atmosphere. The lower end is communicated with the water suction negative pressure area of the pump impeller and is positioned at a position which is less than 10cm away from the pump impeller. Specifically, when the submersible pump is operated, a negative pressure region water absorption region is formed, and in the negative pressure region, extremely high negative pressure is formed, and atmosphere is connected to the negative pressure region and is directly sucked into the impeller. The area is closer to the impeller, the negative pressure is higher, so the lower end of the air inlet pipe is reasonably 10cm away from the area, and air can be sucked by the negative pressure.

The pump impeller water suction negative pressure region has a mixing space for mixing the atmosphere with water. The pump impeller water suction negative pressure region has a mixing space for mixing the atmosphere with water.

Generally, a sieving screen for pushing off slag by a pump impeller is arranged at the lower part of a pump body of the submersible pump, namely at the position of the pump impeller, and a space part surrounded in the sieving screen of the utility model forms a mixing space for mixing air and water; the lower end of the air inlet pipe penetrates through the screen to reach a space part inside the screen, and the atmosphere and the water rotate at a high speed under the stirring of the impeller to form mixed flow, and then the mixed flow enters the pump impeller.

Of course, the lower part of the pump body of a particular submersible pump may not be provided with a screen, and then a virtual cylinder space is provided below the submersible pump, and the virtual cylinder space is as follows: the calibration aspect of the cylinder space consists of two parameters, one is the base and one is the height. The utility model provides a bottom surface and high definition as follows: the circle formed by the rotation of the impeller of the submersible pump is taken as the bottom surface; the height is from the axial lead direction of the impeller of the submersible pump to the position 10cm away from the impeller of the submersible pump. Within the virtual cylindrical space, there is a mixing space where the atmosphere is mixed with water. The atmosphere and water in the mixing space rotate at high speed under the stirring of the impeller to form mixed flow, and then the mixed flow enters the pump impeller.

The internal cross-sectional area of the air inlet pipe needs to be calibrated, the internal cross-sectional area of the air inlet pipe is too large, so that too much air is sucked, however, when pumps work mechanically, a cavitation parameter exists, namely, within the range of the parameter, water can be normally sucked, pumped and drained, and if the parameter is exceeded, the water cannot be normally sucked and drained, which is called a cavitation critical point. Actually, the internal cross-sectional area of the air inlet pipe needs to be calibrated, namely the air inlet flow of the air inlet pipe is limited, and the requirements are as follows: the cross-sectional area in the pipe is required to be smaller than the maximum cross-sectional area of the cavitation critical point of the submersible pump, so that the input air flow reaches. Different submersible pumps have different power and different flow rates, so that the submersible pump can normally work under the condition of the calibrated pipe inner sectional area.
