The cover serves for aesthetics and for mounting components such as the control box. The cover includes a base and a cover that mates with the base. The cover is an open-end cover that snaps onto the base from top to bottom; alternatively, the cover includes an upper cover portion, a middle cylinder portion, and a lower cylinder portion, which are sequentially fixedly connected or detachably connected to form an open-end cover that snaps onto the base from top to bottom. The main body of the water pump has multiple interfaces for connecting to external pipelines, and the cover has corresponding through holes for pipeline connections. When maintenance or other operations are required on the water pump, the entire water pump must first be disassembled from the external pipelines, then the cover on the water pump must be removed, and finally the main body of the water pump must be repaired. After the repair is completed, the above steps are repeated in reverse to connect the water pump to the external pipelines.

[0022] The main improvement of this technical solution is that the cover includes a first half-shell 1 and a second half-shell 2 that are longitudinally spliced ​​together. The longitudinal splicing surfaces of the first half-shell 1 and the second half-shell 2 are arranged along the axial direction of the water pump body 3 or along the radial direction of the water pump body 3. When disassembling and assembling the first half-shell 1 and / or the second half-shell 2, the entanglement and restriction of the external pipeline can be avoided, and the half-shell and / or the second half-shell 2 can be easily disassembled.

[0023] Specifically, by improving the structure of the cover, the existing upper and lower assembly relationship of the cover is changed to a left-right or front-back assembly relationship. Since the water inlet, outlet and injection port on the water pump body 3 are located at one end of the cover, the improved cover can avoid the water inlet, outlet and injection port during disassembly and assembly. This allows the water pump body 3 to be repaired without disassembling the entire cover, only half of the cover needs to be disassembled. This simplifies the maintenance operation process, greatly reduces maintenance time, and makes maintenance easy.

[0024] The above technical solution involves several ways of setting the through hole 4:

[0025] The first technical solution: all the through holes 4 are set on the first half shell 1.

[0026] In the technical solution, the second half shell 2 is not provided with the through holes 4, so that the connection between the external pipeline and the water pump body 3 does not need to be disassembled, the second half shell 2 is not restricted by the external connecting pipeline during disassembly, and the second half shell 2 can be directly disassembled. When the water pump body 3 needs to be repaired, the water pump body 3 in the cover shell can be partially exposed by disassembling the second half shell 2, so that the water pump body 3 is conveniently, time-savingly and labor-savingly repaired.

[0027] The second technical solution is that the first half shell 1 is provided with the plurality of through half holes, the second half shell 2 is provided with a plurality of corresponding through half holes, and the plurality of through half holes on the first half shell 1 and the plurality of through half holes on the second half shell 2 are combined into the plurality of complete through holes 4.

[0028] In the technical solution, each through hole 4 is formed by combining the corresponding through half holes on the first half shell 1 and the second half shell 2. When the water pump body 3 needs to be repaired, the water pump body 3 can be partially exposed by disassembling the first half shell 1 and / or the second half shell 2, and the water pump body 3 is not restricted by the external pipeline during disassembly, so that the water pump body 3 is conveniently, time-savingly and labor-savingly repaired.

[0029] The third technical solution is that the first half shell 1 is provided with the through holes 4 and the through half holes, the second half shell 2 is provided with corresponding through half holes, and the through half holes on the first half shell 1 and the through half holes on the second half shell 2 are correspondingly arranged and combined into the complete through holes 4.

[0030] The technical solution is a combination of the above two technical solutions. When the water pump body 3 needs to be repaired, the water pump body 3 in the cover shell can be partially exposed by disassembling the second half shell 2, so that the water pump body 3 is conveniently, time-savingly and labor-savingly repaired. During disassembly, the water pump body 3 is not restricted by the external pipeline.
