Technical Field

[0001] This utility model belongs to the field of pumps, and relates to a self-priming pump, and particularly to a high-efficiency and energy-saving self-priming pump. Background Technology

[0002] Self-priming pumps, as essential equipment for liquid transportation, are widely used in agricultural irrigation, industrial circulating water systems, municipal engineering, and domestic water supply. However, traditional self-priming pumps have many shortcomings in flow control, such as inaccurate flow regulation, inability to automatically adapt to changes in operating conditions, and complex structures leading to maintenance difficulties. These problems not only affect the working efficiency of self-priming pumps but may also lead to energy waste and equipment damage. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a high-efficiency, energy-saving, self-priming pump that can precisely adjust the flow rate and automatically adapt to changes in operating conditions.

[0004] The purpose of this utility model can be achieved through the following technical solution: a high-efficiency and energy-saving self-priming pump, including a control system and a pump body with an outlet and an inlet, characterized in that a flow regulating mechanism for adjusting the outlet flow is provided inside the outlet of the pump body, and a flow transmission device for real-time monitoring of the pumped liquid is also provided inside the outlet of the pump body.

[0005] The flow regulation mechanism includes multiple guide vanes for regulating the outlet flow rate, a central shaft fixed inside the pump body outlet, a synchronization component that can synchronously drive the guide vanes to rotate, and a drive component that drives the synchronization component to move.

[0006] The pump body has an annular cavity inside the outlet side wall for mounting the synchronization component.

[0007] The guide vane is arranged in a fan-shaped structure, and both ends have a rotating shaft that can drive the guide vane to rotate. One end of the rotating shaft passes into the inside of the ring cavity and is connected to the synchronous component for transmission.

[0008] The synchronization component includes multiple bearing seats evenly distributed in the annular cavity, rotatable rotating parts, and multiple connecting rods for connection. The bearing seats are fixed to the side wall of the annular cavity and are movably connected to the corresponding rotating shafts. The rotating parts are fixedly connected to the rotating shafts that pass through the annular cavity. The rotating parts are connected in sequence through connecting rods and driven by a driving component to rotate, thereby synchronously driving the other rotating parts to rotate and controlling the rotation of the guide vanes.

[0009] In the aforementioned high-efficiency and energy-saving self-priming pump, the central shaft extends radially outward with several connecting ribs for connection and support. These connecting ribs can be arranged and distributed sequentially at intervals along the outer side of the central shaft in a circumferential direction.

[0010] In the aforementioned high-efficiency and energy-saving self-priming pump, the guide vane has a rotating shaft at one end that is movably connected to the outside of the central shaft, and the other end of the rotating shaft passes through and movably connects the pump body and the bearing seat, with a rotating component fixed at the end.

[0011] In the aforementioned high-efficiency and energy-saving self-priming pump, the guide vane is driven by a drive component to rotate one of the rotating components, and a connecting rod structure is used to synchronously drive the other rotating components to rotate, thereby driving the guide vane to rotate.

[0012] Compared with existing technologies, this high-efficiency and energy-saving self-priming pump has the following advantages:

[0013] 1. The use of flow sensors and control systems enables precise monitoring and intelligent adjustment of flow, improving the working efficiency and accuracy of the self-priming pump;

[0014] 2. The flow regulation mechanism is designed to precisely control the flow rate, avoiding unnecessary energy waste and improving the energy-saving performance of the self-priming pump. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, this high-efficiency energy-saving self-priming pump includes a control system and a pump body 1 with an outlet and an inlet. A flow regulating mechanism for adjusting the water flow rate is set inside the outlet of the pump body 1. A flow transmission device for real-time monitoring of the pumped liquid is also set inside the outlet of the pump body 1. The flow regulating mechanism includes multiple guide vanes 2 that can be used to adjust the water flow rate, a central shaft 3 fixed inside the outlet of the pump body 1, a synchronization component that can synchronously drive the guide vanes 2 to rotate, and a drive component 5 that drives the synchronization component to move. The pump body 1 has an annular cavity 6 inside the outlet side wall for the installation of the synchronization component. The guide vane 2 is arranged in a fan-shaped structure and has a rotating shaft 4 at both ends that can drive the guide vane 2 to rotate. One end of the rotating shaft 4 passes into the annular cavity 6 and is connected to the synchronization component. The synchronization component includes multiple bearing seats 8 evenly distributed in the annular cavity 6, a rotatable rotating component 7, and multiple connecting rods 9 for connection. The bearing seats 8 are fixed on the side wall of the annular cavity 6 and are movably connected to the corresponding rotating shaft 4. The rotating component 7 is fixedly connected to the rotating shaft 4 that passes into the annular cavity 6. The rotating component 7 is connected in sequence through the connecting rod and is driven by the driving component 5 to rotate, thereby synchronously driving the other rotating components 7 to rotate and controlling the rotation of the guide vane 2.

[0021] The use of flow sensors and control systems enables precise monitoring and intelligent adjustment of flow, improving the efficiency and accuracy of the self-priming pump.

[0022] The flow regulation mechanism is designed to precisely control the flow rate, avoiding unnecessary energy waste and improving the energy-saving performance of the self-priming pump.

[0023] To elaborate further, in order to reduce the impact intensity of water flow, the central axis 3 has several connecting ribs 10 extending radially outward for connecting and supporting. These connecting ribs 10 can be arranged and distributed in a circumferential direction along the outside of the central axis 3.

[0024] To elaborate further, in order to achieve the movable connection design of the guide vane 2 inside the outlet of the pump body 1, the rotating shaft 4 at one end of the guide vane 2 is movably connected to the outside of the central shaft 3, and the rotating shaft 4 at the other end passes through and movably connects the pump body 1 and the bearing seat 8. A rotating component 7 is fixed at the end. The guide vane 2 drives one of the rotating components 7 to rotate through the driving component 5, and uses the connecting rod 9 structure to synchronously drive the other rotating components 7 to rotate, thereby driving multiple guide vanes 2 to rotate. The rotating shaft 4 and the guide vane 2 are integrally formed, which facilitates the connection strength through its movable connection.
