[0001] This utility model belongs to the field of water pump technology, and relates to a booster pump, and particularly to a novel permanent magnet intelligent booster pump. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals, and can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Existing water pumps cannot filter out harmful substances and small particles in the water flow, resulting in poor water quality. At the same time, long or large debris in the water flow cannot be processed during transportation, which can easily clog the pump's pipes and damage the impeller. During pump operation, backflow of liquid in the outlet pipe will affect the pump's filtration and purification effect on the liquid. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel permanent magnet intelligent booster pump that is easy to install and offers multi-stage boosting.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel permanent magnet intelligent booster pump includes a pump body, on which a control main board for controlling the pump body and a drive motor for driving the pump body are provided. The pump body is provided with an inlet for water intake and an outlet for water discharge. The pump body has a pump chamber for liquid flow, a pressure tank assembly at the side end of the pump body, an impeller assembly connected to the motor shaft of the drive motor, and the impeller assembly is located within the pump chamber of the pump body. The impeller assembly includes a front guide vane, a first-stage impeller, a rear guide vane, a second-stage impeller, and a valve seat. A filter assembly is provided within the pump body relative to the inlet, and a check valve assembly is provided within the pump body relative to the outlet.

[0006] In the aforementioned novel permanent magnet intelligent booster pump, the filter assembly includes an installation part and a filter screen. The filter assembly and the water inlet are arranged at a 90-degree angle, and the length of the filter screen is greater than the diameter of the water inlet.

[0007] In the aforementioned novel permanent magnet intelligent booster pump, the check valve assembly includes a mounting frame, a check valve component, and a return spring. The check valve component is attached to the pump body to close the outlet. The return spring is positioned between the check valve component and the mounting frame, and its action controls the check valve component to close and open the outlet.

[0008] In the aforementioned novel permanent magnet intelligent booster pump, a temperature sensor for sensing temperature is installed outside the pump body.

[0009] In the aforementioned novel permanent magnet intelligent booster pump, a control housing is provided outside the pump housing, the pump body is fixedly connected to the drive motor by fixing bolts, and the pressure tank assembly is connected to the pump body by fixing bolts.

[0010] Compared with existing technologies, this novel permanent magnet intelligent booster pump has the following advantages: 1.

[0015] 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.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, this novel permanent magnet intelligent booster pump includes a pump body 1. The pump body 1 is equipped with a control main board 2 and a drive motor 3 for driving the pump body 1. The pump body 1 has an inlet 4 for water intake and an outlet 5 for water discharge. The pump body 1 has a pump chamber for liquid flow. A pressure tank assembly 6 is located on the side of the pump body 1. The motor shaft of the drive motor 3 is connected to an impeller assembly 7, which is disposed within the pump chamber of the pump body 1. The impeller assembly 7 includes a guide vane. The impeller assembly 7 comprises a front guide vane 8, a first-stage impeller 9, a rear guide vane 10, a second-stage impeller 11, and a valve seat 12. A filter assembly 13 is located within the pump body 1 relative to the inlet 4, and a check valve assembly 14 is located within the pump body 1 relative to the outlet 5. A plug is provided on the pump body 1, and the filter assembly 13 is threaded onto the plug. A water passage gap exists between the front guide vane 8 and the rear guide vane 10. The front guide vane 8 has several snap-fit ​​parts 15, and the rear guide vane 10 has snap-fit ​​grooves that mate with the snap-fit ​​parts 15. When the impeller assembly 7 is installed, the snap-fit ​​parts 15 on the front guide vane 8 engage with the snap-fit ​​grooves on the rear guide vane 10, thus fixing the front guide vane 8 onto the rear guide vane 10. This snap-fit ​​method facilitates the disassembly and replacement of the impeller assembly 7.

[0017] To elaborate further, the filter assembly 13 includes a mounting part 16 and a filter screen 17. The filter assembly 13 and the water inlet 4 are arranged at a 90-degree angle, and the length of the filter screen 17 is greater than the diameter of the water inlet 4.

[0018] To elaborate further, the liquid flows in from the inlet 4 of the pump body 1, is filtered by the filter assembly 13 at the inlet 4, and then enters the impeller assembly 7 through the pump chamber. The drive motor 3 drives the impeller assembly 7 to rotate, so that the liquid flows out from the outlet 5.

[0019] To elaborate further on the liquid check, when the water pump is running, the liquid provides an impact force to the check element 19, causing the check element 19 to move upward. The return spring 20 is in a compressed state, and the liquid flows out from the outlet 5. When the water pump stops running, the return spring 20 rebounds, and the check element 19 closes the outlet 5 to prevent the liquid from flowing back.

[0020] To elaborate further, the check valve assembly 14 includes a mounting frame 18, a check valve 19, and a return spring 20. The check valve 19 is attached to the water pump body 1 to close the outlet 5. The return spring 20 is disposed between the check valve 19 and the mounting frame 18. The action of the return spring 20 controls the check valve 19 to close and open the outlet 5.

[0021] To elaborate further, a temperature sensor 21 for sensing temperature is installed on the outside of the water pump body 1. The temperature sensor 21 can detect the liquid entering the water pump body 1, and the result is reflected on the control panel by the control system inside the water pump body 1.

[0022] To elaborate further, a control housing 22 is provided outside the water pump housing. The water pump body 1 is fixedly connected to the drive motor 3 by fixing bolts, and the pressure tank assembly 6 is connected to the water pump body 1 by fixing bolts.
