Problems solved by technology

[0003] The diameter of the water inlet on the pump body of the existing submersible pump is usually fixed. The large particles at the inlet can pass through the residual water level of the dirt and cannot be drained. The small inlet can only be used to pump clean water.

Embodiment 1

[0028] Such as Figure 1-3 As shown, the pump body structure of a submersible pump provided in this embodiment includes a pump body 1, the bottom of the pump body 1 is provided with a water inlet 2, and a base 3 is provided below the pump body 1, Four first through holes 4 are distributed on the side wall of the base 3 along the perimeter direction of the side wall. The lower part of the pump body 1 extends into the base 3, and also includes a pump body 1 extending into the base through the restriction. 3 different depths to realize the limit mechanism for changing the overlapping area of ​​the pump body 1 and the first through hole 4 .

[0029] The above-mentioned limiting mechanism includes an adjustment ring 5 that is sleeved on the pump body 1 and can only rotate around its central axis. The lower bottom of the adjustment ring 5 forms a pair of symmetrically distributed concave notches 6; Two symmetrically distributed second through holes 7 on the side wall of the base 3,...

Embodiment 2

[0031] The pump body structure of a kind of submersible pump provided in this embodiment, its general structure is consistent with embodiment 1, as Figure 4 shown, but the limiting mechanism described in this embodiment includes an adjusting ring 5 screwed on the pump body 1; two second through holes 7 symmetrically distributed on the side wall of the base 3, The second through holes 7 are opened parallel to the central axis of the adjustment ring 5, and the openings are rectangular, and the lower half of each second through hole 7 forms a bayonet 8; the base 3 extends toward the adjustment ring and a support boss 9 abutting against the lower bottom edge of the lower bottom edge; and a pair of buckle members 10 connected to the base 3 and located in the corresponding second through holes 7 .

Abstract

The invention discloses a pump body structure of an immersible pump. The pump body structure comprises a pump body. A water inlet is formed in the bottom of the pump body. A base is arranged below the pump body. A first through hole is distributed in the side wall of the base. The lower part of the pump body extends into the base. The pump body structure further comprises a limiting mechanism, and by means of the limiting mechanism, the overlapping area of the pump body and the first through hole changes through limitation of different depths by which the pump body extends into the base. The pump body structure achieves the technical purpose that the caliber of a water inlet in the immersible pump body can be changed, and therefore when the provided immersible pump is used, the passing performance and water sucking-dry performance of particles of the pump can be adjusted.

Description

technical field [0001] The invention relates to a pump body structure, in particular to a pump body structure of a submersible pump. Background technique [0002] The submersible pump is an important equipment for extracting water from deep wells. When in use, the whole unit submerges into the water to work. [0003] The diameter of the water inlet on the pump body of the existing submersible pump is usually fixed. The large particles at the inlet can pass through the residual water level of the dirt and cannot be drained. The small inlet can only be used to pump clean water. . [0004] In view of the above situation, the applicant believes that it is necessary to make further structural improvements to the existing submersible pump. Contents of the invention [0005] The object of the present invention is to provide a pump body structure of a submersible pump with variable water inlet caliber in order to solve the above-mentioned deficiencies in the prior art. [0006]...
