The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0023] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0024] A submersible sewage pump with adjustable impeller clearance comprises a sewage pump body 1, an end cover 2 is arranged on one side of the sewage pump body 1, a cable 3 is arranged on the side of the end cover 2 away from the sewage pump body 1, a flange 4 is arranged on the side of the sewage pump body 1 away from the end cover 2, a second connecting flange 5 is arranged on one side of the flange 4, a gasket 6 is arranged on the side of the second connecting flange 5 away from the flange 4, an impeller 6 is arranged on the side of the gasket 6 away from the second connecting flange 5, an impeller cover 8 is arranged on one side of the impeller 7, a first fixing screw hole 9 is arranged on one side of the impeller cover 8, a detachable impeller cover 10 is arranged on one side of the impeller cover 8, a second fixing screw hole 11 is arranged on the side of the detachable impeller cover 10 close to the first fixing screw hole 9, a base 12 is arranged on the side of the impeller cover 8 away from the sewage pump body 1, and a water inlet 13 is arranged on one side of the impeller cover 8.

[0025] Specifically, refer to Figure 2 The detachable impeller cover 10 is fixed by bolts in cooperation with the first fixing screw hole 9 and the second fixing screw hole 11, so as to facilitate disassembly and replacement, so as to realize the maintenance and care of the impeller.

[0026] Furthermore, the removable impeller cover 10 corresponds to the impeller cover 8 in an arc-shaped mirror-image structure, wherein the two ends of the removable impeller cover 10 are fitted into the two side surfaces of the impeller cover 8 and are screwed and locked, so as to facilitate the removal of the removable impeller cover 10 and timely clean the impeller 7 of impeller impeller 7.

[0027] Furthermore, the impeller cover 8 is made of a transparent or translucent material, so that the operator can visually observe the working status of the impeller, which is convenient for timely detection and handling of problems.

[0028] For details, please refer to Figure 3 A sealing gasket is arranged between the sewage pump body 1 and the flange 4, which further enhances the sealing performance of the pump body and prevents sewage leakage. The gasket 6 is arranged at the connection between the second connecting flange 5 and the impeller cover 8, and the gasket 6 is a detachable structure, which is convenient for removing and replacing the gasket, thereby adjusting the impeller clearance.

[0029] Working process of the utility model: A submersible sewage pump with an adjustable impeller clearance designed by the scheme is used. During the use of the sewage pump, the detachable shield design of the submersible sewage pump greatly facilitates the maintenance and care of the pump body. The shield consists of two parts: an impeller cover of the main part and a detachable impeller cover of the detachable part. The two parts are fixed with the first fixing screw hole and the second fixing screw hole by bolts or other fastening devices to form a complete shield structure to protect the impeller from external impurities. During the operation of the pump body, sewage enters the pump body through the water inlet, and the sewage is extracted and discharged through the rotation of the impeller. The existence of the detachable shield effectively prevents larger impurities or solid particles from entering the pump body, protecting the normal operation of the impeller and other key components. When the pump body needs to be maintained or the impeller needs to be replaced, the operator only needs to loosen the bolts or other fastening devices to easily remove the detachable impeller cover to expose the impeller part. In this way, the impeller can be easily cleaned, inspected or replaced without disassembling the entire pump body, which greatly simplifies the maintenance process and improves work efficiency. At the same time, the transparent design of the removable cover also facilitates observation and monitoring of the inside of the pump body.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
