[0002] Submersible sewage pumps are widely used in sewage discharge treatment. Before a submersible sewage pump is officially put into use, a single-unit commissioning test needs to be carried out on the submersible sewage pump. The single-unit commissioning test can check the running state and performance of the submersible sewage pump, ensure that the submersible sewage pump can operate safely after being put into use, and extend the service life of the submersible sewage pump. In the prior art, most of the methods for commissioning submersible sewage pumps are as follows: First, find a water source and a sump, introduce the water source into the sump through a pipeline, place the submersible sewage pump in the sump, make the inlet pipe of the submersible sewage pump submerge below the water surface of the sump, and the outlet pipe of the submersible sewage pump extend out of the water surface of the sump. Then start the submersible sewage pump so that the submersible sewage pump can carry out the single-unit commissioning of the submersible sewage pump in the sump. However, since it is necessary to find a water source and a sump, and the size and depth of the sump are random, some of the found sumps are difficult to meet the requirements of the submersible sewage pump commissioning test, resulting in a waste of a large amount of human and time resources for this submersible sewage pump commissioning method.

[0030] Further, as a preferred embodiment, a pipeline flowmeter 5 is provided on the upper part of the first portion 21.

[0031] Further, as a preferred embodiment, the pipeline flowmeter 5 is used to detect the flow rate at the outlet of the submersible sewage pump.

[0032] Further, as a preferred embodiment, a valve 6 is provided on the lower part of the first portion 21.

[0033] Further, as a preferred embodiment, the valve 6 is used to adjust the outlet flow rate of the submersible sewage pump.

[0034] Further, as a preferred embodiment, the flange assembly includes: a first flange 3 and a second flange 4. The first flange 3 and the second flange 4 are connected by bolts. The first flange 3 is provided at one end of the first portion 21, and the second flange 4 is provided at one end of the connecting pipe 9.

[0035] Further, as a preferred embodiment, the connecting pipe 9 is tapered.

A water outlet pipe of the submersible sewage pump is connected to the connecting pipe 9 of the present device. There are two connection methods between the water outlet pipe and the connecting pipe 9. One method is through the combination connection of the third flange 8 and the flange provided on the water outlet pipe. Among them, the inner diameter of the lower end of the connecting pipe 9 corresponds to the inner contour of the pipe hole of the third flange 8. Because the inner diameters of the water outlet pipes have different sizes and styles, that is, the pipe holes of the flanges on the water outlet pipes have different sizes and styles, so different styles of the third flange 8 can be selected correspondingly; the second method is through the threaded connection head 7 and the water outlet pipe for connection. The lower end of the connection head 7 is provided with an external thread, and one end of the water outlet pipe is provided with an internal thread.

[[ID=~14]]

[0046] In a further embodiment of the present utility model, since the flow rate of the submersible pump is too large, it is easy to cause the device to tip over inside the water tank 1. Therefore, a buckle for the circulation pipe 2 can be installed on the water tank 1, and the third part 23 of the circulation pipe 2 can be fixed through the buckle on the water tank 1 to prevent the device from tipping over.
