Description

Technical Field

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

[0002] A horizontal self-priming pump is a type of centrifugal pump. Its main feature is that it can automatically expel air from the pump body before starting, achieving self-priming. It eliminates the need for a foot valve on the inlet pipe. This type of pump can be used as a regular centrifugal pump or a regular self-priming pump. Horizontal self-priming pumps have advantages such as simple structure, convenient maintenance, and long service life, and are therefore widely used. While existing horizontal self-priming pumps can perform water intake and drainage functions, controlling the water intake speed and pressure requires additional equipment installed at the inlet.

[0003] Chinese patent application CN221921370U discloses a horizontal self-priming pump water supply control device, comprising: a base, a self-priming pump body fixedly mounted on the top of the base, a water inlet pipe fixedly mounted on the left side of the top of the self-priming pump body, and a water outlet pipe fixedly mounted on the left side of the top of the self-priming pump body. This invention, by incorporating a sphere, a rod, a motor, and a hinge rod, allows the operator to adjust the water supply speed and pressure by starting the motor. This causes the rotating shaft to rotate, which in turn drives the hinge rod to move. The hinge rod then pulls the connecting plate and the rod inward, causing the sphere to gradually enter the interior of the water outlet pipe. This reduces the water outlet area of ​​the water outlet pipe, thereby enabling adjustment of the water pressure and improving the device's flexibility and ease of use.

[0004] While existing water pumps can adjust the flow rate and pressure, they cannot provide quantitative adjustment as needed. Furthermore, the filter screen needs to be removed for cleaning when filtering impurities, which is quite cumbersome.

[0005] To address these issues, we provide a horizontal self-priming pump water supply control device. Utility Model Content
