Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and relates to a submersible sewage pump, and particularly to a novel submersible sewage pump. Background Technology

[0002] Due to the influence of its working environment, submersible sewage pumps are prone to the introduction of particulate impurities at the flange connection near the outlet, which accelerates the wear of internal parts and affects their performance. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a new type of submersible sewage pump with improved performance.

[0004] The objective of this utility model can be achieved through the following technical solution: A novel submersible sewage pump, comprising a pump body and a water outlet pipe on the pump body, characterized in that the water outlet pipe has a flange 1, the pump body has a flange 2 connected to the flange 1, the flange 1 has an axially extending transition sleeve 1, the transition sleeve 1 is formed with a plurality of lace-edged partition parts 1, a lace groove 1 formed on the transition sleeve 1 is formed between two adjacent lace-edged partition parts 1, the flange 2 has an axially extending transition sleeve 2 fitted onto the transition sleeve 1, the inner wall of the transition sleeve 2 is provided with a plurality of lace grooves 2 for the lace-edged partition parts 1 to be inserted, a lace-edged partition part 2 formed on the transition sleeve 2 is formed between two adjacent lace grooves 2, and the lace-edged partition parts 1 and lace-edged partition parts 2 are arranged alternately adjacent to each other.

[0005] In the aforementioned novel submersible sewage pump, a flat gasket is provided between the transition sleeve 2 and the flange 1.

[0006] In the aforementioned novel submersible sewage pump, flange one and flange two are connected by a nut and screw structure.

[0007] In the aforementioned novel submersible sewage pump, the inner wall of one end of the transition sleeve has a barrier portion that extends into the second transition sleeve.

[0008] Compared with existing technologies, this new type of submersible sewage pump has the advantages of preventing impurities from entering directly from the pump's output end, reducing wear on the inner walls of nearby internal parts, and improving performance. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1-4 As shown, this novel submersible sewage pump includes a pump body 1 and an outlet pipe 2 on the pump body 1. The outlet pipe 2 has a flange 3, and the pump body 1 has a flange 4 connected to the flange 3. The flange 3 has an axially extending transition sleeve 5, and the transition sleeve 5 has several decorative partitions 6 formed thereon. A decorative groove 7 is formed between two adjacent decorative partitions 6 on the transition sleeve 5. The flange 4 has an axially extending transition sleeve 8 fitted onto the transition sleeve 5. The inner wall of the transition sleeve 8 has several decorative grooves 9 for the decorative partitions 6 to be inserted into. A decorative partition 10 is formed between two adjacent decorative grooves 9 on the transition sleeve 8. The decorative partitions 6 and 10 are arranged alternately and adjacently, which greatly blocks the incorporation of particulate impurities, ensuring that the impurity fluid enters from the water inlet of the pump body 1, so as to work in an orderly and efficient manner and improve the performance.

[0016] In addition, there is a flat gasket 11 between the transition sleeve 2 8 and the flange 1 3 to further prevent particles from entering. If the exposed flat gasket 11 wears out after long-term use, a blocking structure is formed by the staggered lace grid parts 1 and 2.

[0017] Preferably, flange 3 and flange 4 are connected by a nut and screw structure 12.

[0018] Meanwhile, a barrier portion 13 extending into the transition sleeve 2 is provided on the inner wall of the end of the transition sleeve 1 5, and a groove is provided in the transition sleeve 2 8 for the barrier portion 13 to enter, further enhancing the effect of blocking impurities.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0020] Although this document frequently uses terms such as pump body 1, outlet pipe 2, flange one 3, flange two 4, transition sleeve one 5, decorative partition part one 6, decorative groove one 7, transition sleeve two 8, decorative groove two 9, decorative partition part two 10, flat gasket 11, nut and screw structure 12, and barrier part 13, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
