Description

Technical Field

[0001] This utility model belongs to the field of self-priming pump technology, and relates to a self-priming pump, particularly a self-priming pump with a filter structure. Background Technology

[0002] Self-priming pumps all adopt an axial return pump body structure. The pump body consists of a suction chamber, a liquid storage chamber, a vortex chamber, a return hole, and a gas-liquid separation chamber. After the pump starts normally, the impeller draws in the liquid stored in the suction chamber and the air in the suction pipe together, and they are completely mixed in the impeller. Under the action of centrifugal force, the liquid carries the gas and flows towards the outer edge of the vortex chamber.

[0003] Existing self-priming pumps leave impurities in the water inside during use. Over time, these impurities accumulate, causing blockages and corrosion of the pump's inner walls, thus affecting the pump's performance. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a high-strength self-priming pump with a filtration structure.

[0005] The objective of this utility model can be achieved through the following technical solution: A self-priming pump with a filtration structure, comprising a pump body, characterized in that a drive motor is provided at the rear end of the pump body, and the motor shaft of the drive motor extends into the pump body and is connected to two impeller assemblies. The pump body has an inlet chamber, a sealing chamber, and a flow chamber. A filter element for filtration is provided in the inlet chamber. The impeller assemblies are located in the flow chamber and are driven by the drive motor. An installation part is integrally provided in the pump body and located in the inlet chamber. One end of the filter element is fixedly installed on the installation part, and the other end of the filter element extends into the flow chamber. The filter element has a flow pipe for liquid flow inside. The sealing chamber and the flow chamber are separated by a partition.

[0006] In the above-mentioned self-priming pump with a filtration structure, the filter element consists of an inlet sleeve and an mounting sleeve. The outer peripheral wall of the inlet sleeve has several inlet holes for water intake, and a filter screen for filtration is provided at the inlet holes of the inlet sleeve.

[0007] In the aforementioned self-priming pump with a filtration structure, the pump body is provided with a water outlet component, which is connected to its interior.

[0008] Compared with existing technologies, this self-priming pump with a filtration structure filters the liquid entering the pump body by installing a filter element inside the pump body, thereby improving the service life of the pump body. Attached Figure Description

[0012] 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.

[0013] like Figure 1 , Figure 2 As shown, this self-priming pump with a filtration structure includes a pump body 1. A drive motor 2 is located at the rear end of the pump body 1, and the motor shaft of the drive motor 2 extends into the pump body 1 and is connected to two impeller assemblies 3. The pump body 1 has an inlet chamber 4, a sealing chamber 5, and a flow chamber 6. The sealing chamber 5 is used to enhance the sealing performance of the pump body 1 and prevent the filter element 7 from leaking due to reduced sealing performance after long-term use. The filter element 7 is installed in the inlet chamber. The impeller assemblies 3 are located in the flow chamber 6 and are driven by the drive motor 2. The pump body 1 is integrally provided with a mounting part 8 located in the inlet chamber 4. One end of the filter element 7 is fixedly installed on the mounting part 8, and the other end of the filter element 7 extends into the flow chamber 6. The filter element 7 has a flow pipe 9 for liquid flow inside. The sealing chamber 5 and the flow chamber 6 are separated by a partition.

[0014] To elaborate further, the filter element 7 consists of an inlet sleeve 10 and an installation sleeve 11. The outer peripheral wall of the inlet sleeve 10 is provided with several inlet holes for water intake, and a filter screen 12 for filtration is provided at the inlet holes of the inlet sleeve 10.

[0015] To elaborate further, under the pressure of the impeller, the liquid enters the inlet chamber 4 through the inlet hole of the water pump body 1, then enters the filter element 7 through the inlet hole of the inlet sleeve 10, is filtered by the filter screen 12 of the inlet hole, then enters the flow chamber 6, and finally flows out from the outlet of the outlet element 13.

[0016] To elaborate further, the water pump body 1 is provided with a water outlet 13, which is connected to its interior.

[0017] 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.

[0018] Although this document frequently uses terms such as pump body 1, drive motor 2, impeller assembly 3, inlet chamber 4, sealing chamber 5, flow chamber 6, filter element 7, mounting part 8, flow pipe 9, inlet sleeve 10, mounting sleeve 11, filter screen 12, and outlet element 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 additional limitation would contradict the spirit of this utility model.
