Detailed Implementation

[0014] 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.

[0015] like Figures 1 to 4As shown, this embodiment includes a pump barrel 1, an upper pump cover 2, a volute shell 3, and a pump base 4. The pump barrel 1 has a cylindrical structure, providing an installation carrier for the internal components. The upper pump cover 2 is installed on one side of the upper end of the pump barrel 1 to protect and seal the upper structure. An upper end cover 5 is fixedly installed inside the pump barrel 1 near the upper end. A fixing plate 21 is integrally formed inside the upper pump cover 2. The upper end cover 5 has a first connecting hole 51 and a second connecting hole 52 at both ends. A first fastening bolt 6 is inserted and fixed in the fixing plate 21 and the first connecting hole 51. The upper pump cover 2 and the upper end cover 5 are stably connected by the first fastening bolt 6, thereby reliably fixing the upper pump cover 2 to the pump barrel 1.

[0016] like Figures 1 to 4 As shown, a motor assembly 7 is installed inside the pump barrel 1. The motor assembly 7 provides the power source for the operation of the submersible pump. A sealing oil chamber 8 is fixedly connected to the lower end of the pump barrel 1. The sealing oil chamber 8 can play a role in sealing and lubrication, preventing external water from entering the interior and affecting the operation of the components. A third connection hole 83 is opened on one side of the sealing oil chamber 8. A long stud bolt 9 is fixed between the second connection hole 52 of the upper end cover 5 and the third connection hole 83 of the sealing oil chamber 8. The long stud bolt 9 passes through the motor assembly 7. Through the through-fixing of the long stud bolt 9, the upper end cover 5, the motor assembly 7 and the sealing oil chamber 8 are precisely positioned and firmly connected, improving the assembly accuracy and stability of the overall structure.

[0017] like Figures 1 to 4 As shown, a pump shaft 10 is inserted through the center of the motor assembly 7. An upper bearing seat 53 is integrally formed at the lower end of the upper cover 5. A lower bearing seat 81 is correspondingly formed at the upper end of the sealing oil chamber 8. A first bearing 54 and a second bearing 82 are respectively installed in the upper bearing seat 53 and the lower bearing seat 81. One end of the pump shaft 10 is connected to the first bearing 54, and the pump shaft 10 passes through the second bearing 82. Through the double bearing support structure, the coaxiality and stability of the pump shaft 10 during high-speed operation are ensured, and vibration and noise during operation are reduced. A stationary ring pressure plate 11 is fixedly installed at the lower end of the sealing oil chamber 8. The volute shell 3 is fitted and connected to the lower end of the stationary ring pressure plate 11. An impeller assembly 12 is installed inside the volute shell 3. The end of the pump shaft 10 away from the first bearing 54 extends into the volute shell 3 and is fixedly connected to the impeller assembly 12. When the motor assembly 7 drives the pump shaft 10 to rotate, it can synchronously drive the impeller assembly 12 to rotate, realizing water pumping operation.

[0018] To elaborate further, such as Figure 1As shown, a water pump handle 13 is installed on the upper end of the upper pump cover 2. A connecting base 131 is integrally formed at the lower end of the water pump handle 13. A second fastening bolt 14 is inserted through the connecting base 131. The second fastening bolt 14 extends into the interior of the upper pump cover 2 and is threadedly connected to the upper pump cover 2, thereby firmly fixing the water pump handle 13 to the upper pump cover 2, which facilitates the handling and movement of the submersible pump. A protective sleeve 132 is also fixedly connected to the lower end of the water pump handle 13.

[0019] To elaborate further, such as Figure 3 and Figure 4 As shown, a connecting through hole 111 is provided in the stationary ring pressure plate 11, and a third fastening bolt 15 is inserted through the connecting through hole 111. The third fastening bolt 15 extends into the sealing oil chamber 8 and is threadedly fixed to the sealing oil chamber 8, thereby achieving the initial fixation of the stationary ring pressure plate 11 and the sealing oil chamber 8. In order to further improve the sealing performance and connection reliability, pan head screws 16 are also inserted and fixed in the sealing oil chamber 8 and the stationary ring pressure plate 11. Through the double fixing structure, the stationary ring pressure plate 11 is prevented from loosening during use, ensuring the sealing effect of the sealing oil chamber 8 and avoiding oil leakage or water seepage.

[0020] To elaborate further, such as Figure 1 As shown, a water outlet section 17 is fixedly installed on the upper side of one side of the vortex shell 3. The water outlet section 17 is connected to the flow channel inside the vortex shell 3 and is used to discharge the water pumped by the impeller assembly 12. A horizontal outlet pad 171 is installed between the water outlet section 17 and the vortex shell 3. The horizontal outlet pad 171 can fill the gap between the two connecting surfaces, improve the sealing of the connection, prevent water leakage during the discharge process, and ensure the pumping efficiency of the submersible pump.

[0021] To elaborate further, such as Figure 1 As shown, the lower end of the volute shell 3 is integrally formed with multiple connecting feet 31. A fourth fastening bolt 18 is inserted and fixed in the connecting feet 31 and the water pump base 4. The fourth fastening bolt 18 realizes a stable connection between the volute shell 3 and the water pump base 4, ensuring the stability of the bottom structure of the submersible pump. A water pump screen 19 is installed between the water pump base 4 and the lower end of the volute shell 3. The water pump screen 19 can filter the water entering the submersible pump, prevent foreign objects from entering the volute shell 3 and the impeller assembly 12, avoid component blockage or wear, and extend the service life of the submersible pump.
