Description

Technical Field

[0001] This utility model relates to the technical field of pump end caps, specifically to a pump body end cap. Background Technology

[0002] The impeller rotates inside the pump to transport or pressurize the fluid medium. In this process, a pump body end cover needs to be installed inside the pump body to allow the fluid medium to pass through while axially limiting the bearings, rotor and seals inside the pump body.

[0003] In the use of existing pumps, it is inevitable that flexible media such as dead leaves, plastic bags, and woven nets will be introduced into the pump body. These impurities are difficult to clean and will also damage the normal operation of the pump's internal components.

[0004] Therefore, there is an urgent need to provide a solution to address the defects and shortcomings of the existing technologies. Summary of the Invention

[0005] In order to overcome the defects and shortcomings of the existing technology, this utility model provides a pump body end cover.

[0012] As a further preferred embodiment of the present invention, one end of each support portion is fixedly connected to the inner wall of the inner hole of the cover, and the other end of each support portion intersects at the center of the inner hole of the cover.

[0013] As a further preferred embodiment of the present invention, the cross-section of each of the support portions is a triangle with a smaller top and a larger bottom.

[0014] As a further preferred embodiment of the present invention, the guide grooves are arranged in a vortex shape at the bottom of the cover.

[0015] As a further preferred embodiment of this utility model, an end slot is provided at the connection position between the guide groove and the cover.

[0016] As a further preferred embodiment of this utility model, the cover body, cover edge, support member and rib are formed into an integral structure.

[0017] Compared with existing technologies, the technical effects that this utility model can achieve include:

[0018] 1) This utility model provides a pump body end cover, which has a support member fixedly installed in the inner hole of the cover body, and several ribs symmetrically arranged on both sides of the support member.

[0025] [First Embodiment]

[0026] like Figure 1-3 The diagram shows a pump body end cover provided in the first embodiment of this utility model, including a cover body 1 and a cover edge 2. The cover edge 2 is fixed to the top of the cover body 1. The cover edge 2 is used to realize the fixed installation of the end cover and the pump body. The specific installation structure is as follows: a fixing part 21 is provided on the outer edge of the cover edge 2, and a fixing hole 22 is provided inside the fixing part 21. The end cover and the pump body can be fixedly connected by passing a fixing member through the fixing hole. Preferably, the fixing part 21 protrudes from the outer edge of the cover edge 2 so as to avoid any adverse effects on the cover edge 2 body while realizing the fixed connection.

[0027] The key improvement of this embodiment compared to the prior art is that a support member 3 is fixedly installed in the inner hole of the cover 1, and several ribs 4 are symmetrically arranged on both sides of the support member 3. The ribs 4 are set in a triangular pyramid shape with a smaller top and a larger bottom, so as to effectively block and adhere to flexible impurities passing through the pump body end cover, prevent flexible impurities from entering the pump body, and facilitate the adhesion of flexible impurities to the support member and ribs, thereby facilitating timely cleaning of flexible impurities, effectively ensuring the normal operation of the pump body and extending its service life.

[0028] Preferably, in this embodiment, the support member 3 has a Y-shaped cross-section in the inner hole of the cover 1, and the support member 3 includes three support parts 31 arranged at equal intervals around the circumference of the inner hole of the cover 1. One end of each support part 31 is fixedly connected to the inner wall of the inner hole of the cover 1, and the other end of each support part 31 intersects at the center of the inner hole of the cover 1, thereby achieving a uniform blocking and adhesion effect on flexible impurities in the circumferential direction.

[0029] To further achieve the blocking and adhesion effect on flexible impurities, the cross-section of each support 31 is set as a triangle with a smaller top and a larger bottom.

[0030] like Figure 3 As shown, in this embodiment, a flow guide groove 5 is also provided at the bottom of the cover 1. The flow guide groove 5 is arranged in a vortex shape at the bottom of the cover 1 to achieve the flow guide effect of the fluid medium. An end slot 51 is provided at the connection position between the flow guide groove 5 and the cover 1 to facilitate the discharge of the fluid medium.

[0031] Preferably, in this embodiment, the cover body 1, cover edge 2, support member 3 and rib 4 are formed into an integral structure to facilitate the overall forming of the end cap.

[0032] This embodiment provides a pump body end cover, in which a support member is fixedly installed in the inner hole of the cover body, and several ribs are symmetrically arranged on both sides of the support member. The ribs are triangular pyramids with a smaller upper part and a larger lower part, thereby effectively blocking and adhering to flexible impurities passing through the pump body end cover. This prevents flexible impurities from entering the pump body and facilitates the adhesion of flexible impurities to the support member and ribs, thereby facilitating timely cleaning of flexible impurities, effectively ensuring the normal operation of the pump body, and extending its service life.

[0033] The spiral centrifugal impeller provided in this embodiment has a counterweight protruding downwards at the bottom of the impeller shaft, on the opposite side of the connection between the blades and the impeller shaft. This counterweight achieves a weight distribution with the blades on the other side, effectively ensuring a balanced mass distribution within the spiral centrifugal impeller itself. This, in turn, guarantees performance while extending service life. Furthermore, the counterweight at the bottom of the impeller shaft, on the opposite side of the connection between the blades and the impeller shaft, provides a degree of obstruction to the impeller shaft, preventing the fluid medium from directly impacting it and protecting the impeller shaft, thus extending its service life.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
