Description

Technical Field

[0001] This utility model belongs to the field of self-priming pump technology, and in particular relates to a pressurizing device for a self-priming pump. Background Technology

[0002] A self-priming pump is a special type of centrifugal pump that can draw in liquid from the lowest point of the pump and pressurize it to deliver it to a designated location without external priming water, thanks to a specific internal design. The pressurization device of a self-priming pump is generally used to increase the internal pressure of the pump body to help the pump quickly draw in water and maintain a stable working pressure during startup.

[0003] For example, China Utility Model Patent No. 202210569291.0 provides a "multi-stage booster device for the inlet of a self-priming pump". This patent includes a base, a first mounting seat fixedly connected to the top of the base, a first drive motor fixedly connected to the top of the first mounting seat, a second mounting seat fixedly connected to the top of the base and to the right of the first mounting seat, and a pump body fixedly connected to the top of the second mounting seat. The pump is boosted by the first booster component, the second booster component and the third booster component to improve the pumping efficiency.

[0004] While the aforementioned document addresses the issue that existing self-priming pumps can only increase water pressure by their own action without a booster structure, resulting in difficulties in pumping water in deeper areas or slow pumping efficiency, the booster structure still has drawbacks such as complexity and inconvenience in maintenance. The self-priming pump has three fixed booster structures with redundant functions, and the fixed connection between the booster structures and the pump makes disassembly and maintenance difficult. Therefore, this document introduces a pressurization device for self-priming pumps. Utility Model Content
