Problems solved by technology
At present, these two pumps are usually designed separately in the market. One submersible pump cannot be used to pump sewage and clean water at the same time. When it is necessary to pump both sewage and clean water, it has to be equipped with two submersible pumps. cause cost increase

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as Figures 1 to 6 As shown, the submersible pump in this implementation includes a housing 2, a drive motor 31, a controller 1, an impeller 32, a plurality of heightening rings 4 of different thicknesses, an end cover 52, an adjusting plate 51, an adjusting bolt 53, and a nut 54. Biological detectors, sonic repellers and water level detection sensors.
[0026] Wherein, the casing 2 is opened downwards, and the casing 2 is provided with a controller 1 and a driving motor 31 electrically connected to the controller 1. An impeller 32 is arranged on the output shaft of the driving motor 31, and an impeller 32 is arranged on the outer wall of the casing 2. A water outlet 21 is provided, the end face of the shell 2 opening downward is flush with the end face of the impeller 32, the outer wall of the shell 2 opening downward is provided...

The invention discloses an immersible pump and a switching method of dirt water pumping and clean water pumping through the immersible pump. The immersible pump comprises a shell, a plurality of height increasing rings of different thicknesses, and an inlet adjusting assembly. The inlet adjusting assembly comprises an end cap and an adjusting plate. The height increasing rings are arranged on the adjusting plate. A plurality of water inlets are formed in the end cap in the circumferential direction. The adjusting plate is provided with a plurality of adjusting blades. The end caps are screwed to a downward opening of the shell. The switching method comprises the following steps that the height increasing rings of the different thicknesses are reselected according to the degree of purity of the pumped water, the distance between the end face of an impeller and the corresponding water inlet is adjusted, the adjusting plate is rotated so that the shielding area of the adjusting blades to the water inlets can be adjusted, and thus the actual size of the water inlets is changed.
Description
technical field [0001] The invention relates to a water pump, in particular to a submersible pump and a switching method for pumping sewage and clean water by using the submersible pump. Background technique [0002] At present, most of the garden submersible pumps on the market are divided into sewage pumps and clean water pumps, which have different requirements for water particles. The water inlet diameter of the sewage pump is large, and at the same time, the distance between the end face of the impeller and the water inlet is relatively large, so that the water inlet flow with relatively large particles of impurities can pass; while the water inlet of the clean water pump is small, the distance between the end face of the impeller and the water inlet The distance is also small, and it is impossible to pump water with large particles of impurities. Different pumps are required for sewage and clean water pumping. At present, these two pumps are usually designed separate...
