AI Technical Summary
In existing submersible electric pumps, the connection gap between the filter cover and the pump body cannot be effectively sealed, causing particulate impurities in the water environment to enter the pump body, causing wear and use of internal components.
A new type of submersible electric pump is designed. By installing screws at the upper and lower ends of the filter cover, and a sealing device is provided between the filter cover and the pump body, including a sealing body and a clamping part formed on the upper and lower ends of the sealing body, the sealing device made of rubber material is extruded and deformed to improve sealing performance.
It effectively improves the sealing performance of submersible electrical pumps, prevents particles and impurities in the water environment from entering the pump body, extends the service life and reduces wear.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water pumps, and relates to a submersible motor pump, in particular to a novel submersible motor pump. Background Art
[0002] At present, after the filter cover on the market is connected to the pump body of the submersible motor pump, there will be a connection gap between the upper and lower ends of the filter cover and the pump body. This gap is usually not sealed, so that particulate impurities in the water environment enter the pump body, resulting in wear of the internal components of the pump body and affecting the use. Summary of the Invention
[0003] The purpose of the utility model is to provide a novel submersible motor pump with high sealing performance for the above problems existing in the prior art.
[0004] The purpose of the utility model can be achieved by the following technical solutions: a novel submersible motor pump, including a pump body and a filter cover arranged on the pump body, characterized in that both the upper and lower ends of the filter cover are installed on the pump body through screws, a sealing device is arranged between the filter cover and the pump body, the sealing device includes a sealing body sealed between the pump body and the filter cover and clamping parts formed at the upper and lower ends of the sealing body, the clamping parts axially extend outward from both ends of the sealing body, and pressure-receiving grooves are formed at both the inner and outer ends of the sealing body.
[0005] In the above novel submersible motor pump, the sealing device is made of rubber material.
[0006] In the above novel submersible motor pump, the end of the clamping part is a circular structure.
[0007] Compared with the prior art, the novel submersible motor pump has the advantage of improving the sealing performance. Brief Description of the Drawings
[0008] Figure 1 is a perspective view of the novel submersible motor pump.
[0009] Figure 2 is a partially enlarged sectional view of the novel submersible motor pump.
[0010] In the figure, 1, pump body; 2, filter cover; 3, sealing body; 4, clamping part; 5, pressure-receiving groove. Detailed Description of the Embodiments
[0011] The following are specific embodiments of the utility model and in combination with the drawings, the technical solutions of the utility model are further described, but the utility model is not limited to these embodiments.
[0012] Such as Figure 1 、 Figure 2As shown in the figure, the novel submersible motor pump includes a pump body 1 and a filter cover 2 provided on the pump body 1. Both the upper and lower ends of the filter cover 2 are installed on the pump body 1 by screws. A sealing device is provided between the filter cover 2 and the pump body 1. The sealing device includes a sealing body 3 sealed between the pump body 1 and the filter cover 2 and clamping portions 4 formed at the upper and lower ends of the sealing body 3. The clamping portions 4 axially extend outward from both ends of the sealing body 3. Pressure-receiving grooves 5 are formed at both the inner and outer ends of the sealing body 3. After the sealing device is connected, the pressure-receiving grooves 5 on both sides thereof are squeezed by the filter cover 2 and the pump body 1, causing a certain squeezing deformation of the sealing device, thereby making the installation of the clamping portions 4 more stable, and further improving the installation reliability of the sealing device and its own sealing performance.
[0013] Preferably, the sealing device is made of rubber material.
[0014] Preferably, the end of the clamping portion 4 is a circular structure.
[0015] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0016] Although terms such as pump body 1, filter cover 2, sealing body 3, clamping portion 4, pressure-receiving groove 5, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
