[0024] Please see Figures 1-6 As shown, this utility model is a combined centrifugal pump, including a support base 111, which provides a stable support foundation for the entire device. A centrifugal pump 113 is bolted to the right side of the top of the support base 111. A water outlet pipe 115 is connected to the top of the centrifugal pump 113. The system also includes an installation mechanism 2, which is connected to the water outlet pipe 115. The installation mechanism 2 optimizes the device compared to traditional equipment by adapting to pipes of different inner diameters in multiple stages and reinforcing the pipes. The installation mechanism 2 includes an adapter component 22, which is installed inside the cavity of the water outlet pipe 115. The adapter component 22 includes a stepped embedded interface 221, with several end faces of different inner diameters on the top of the stepped embedded interface 221. Each of the several end faces on the top of the stepped embedded interface 221 has a positioning groove 222, and each of the positioning grooves 222 has two sealing rings 223 inside its cavity. The installation mechanism 2 also includes a fixing component 21, which is connected to the support base 115. The base 111 abuts against the pipe, and the fixing component 21 is used to reinforce and stabilize the pipe after installation. A motor 112 is bolted to the left side of the top of the supporting base 111. The output end of the motor 112 on the right side is connected to the impeller inside the centrifugal pump 113 via a coupling. An inlet pipe 114 is connected to the side of the centrifugal pump 113 away from the motor 112. The outer wall of the stepped embedded interface 221 is welded to the inner wall of the outlet pipe 115. Several sealing rings 223 are arranged in groups of two, with each group of sealing rings 223... 23 are respectively installed on the inner wall of the positioning groove 222. The water outlet pipe 115 is tapered. The end of the pipe is inserted into the water outlet pipe 115. Contact and positioning are achieved by the stepped embedded interface 221: the embedded positioning groove 222 is limited, and the inner wall sealing ring 223 is deformed by pressure to prevent leakage. Multiple diameters are adapted to different pipe diameters, eliminating intermediate joints, simplifying installation, improving efficiency and stability, and facilitating maintenance and repair. For manufacturers, it reduces the number of pump models and molds, reduces costs, facilitates management, and increases efficiency and revenue.

[0025] The fixing component 21 includes an internally threaded extrusion tube 211, the inner wall of which is threadedly connected to the outer surface of the water outlet pipe 115. The outer wall of the water outlet pipe 115 has several slots 210, each slot 210 having a support rod 212 connected to it via a pin. The outer surface of the water outlet pipe 115 has threaded grooves that match the inner wall of the internally threaded extrusion tube 211. Several limiting grooves 214 are formed inside the edge of the water outlet pipe 115, and each limiting groove 214 has a support rod slidably connected to its inner wall. Each of the support rods 213 has a sliding groove 217 inside. A limiting ring 215 is slidably connected inside each of the sliding grooves 217. The outer surface of the limiting ring 215 is welded to the inner edge of the water outlet pipe 115. Each of the support rods 213 passes through the limiting groove 214 and extends into the cavity of the water outlet pipe 115. Several anti-slip arc-shaped clamps 216 are installed inside the cavity of the water outlet pipe 115. The sides of the anti-slip arc-shaped clamps 216 that are furthest from each other correspond to the support rods 213. Side welding; several grooves 217 are connected to springs 218 on the side of their inner walls away from the anti-slip arc-shaped clamp 216; the side of each spring 218 near the anti-slip arc-shaped clamp 216 is connected to the outer ring of the limiting ring 215; several support rods 213 are in contact with the side of support rod 212 away from the groove 210 on the side away from the groove 210 on the inside of several support rods 212; several support rods 213 are provided with grooves 219 on the side away from the groove 210 on the inside of several support rods 212; and several support rods 213 are provided with grooves 219 on the side away from the anti-slip arc-shaped clamp 216 on the side away from the groove 210 on the inside of several support rods 212. One side of the arc-shaped clamp 216 is slidably connected to the inside of the second slide groove 219 via a pin. When the internal threaded extrusion tube 211 is rotated clockwise, it rises axially along the threaded groove of the water outlet pipe 115, extruding multiple support rods 212 so that they rotate around the pin. The second support rod 213 moves in conjunction with the slide groove 219, and is guided and gathered by the slide groove 217 and the limiting groove 214. Simultaneously, the anti-slip arc-shaped clamp 216 is driven to close and clamp the outer wall of the pipe, achieving a tight and secure fit, enhancing the stability of water supply and the effectiveness of equipment use.

[0026] One specific application of this embodiment is as follows: During use, the external power supply powers the motor 112. The rotor of the motor 112 rotates at high speed, transferring mechanical energy to the impeller inside the centrifugal pump 113. The support base 111 disperses the vibration generated by the operation of the motor 112 and the centrifugal pump 113 through its own rigid structure, avoiding overall equipment displacement and providing a stable foundation for power transmission. The liquid enters the pump casing of the centrifugal pump 113 through the inlet pipe 114. At this time, the impeller rotates at high speed under the drive of the motor 112, with a speed usually of 1000-3000 r / min. The centrifugal force generated by the rotation of the impeller acts on the liquid, causing the liquid to be thrown towards the inner wall of the pump casing along the flow channel between the impeller blades. During the process, the kinetic energy of the liquid increases significantly. The inner wall of the pump casing is designed as a spiral. When the liquid flows in the volute, the cross-sectional area of ​​the flow channel gradually expands, and the kinetic energy is converted into pressure energy. The liquid pressure increases, providing power for long-distance or high-resistance transportation. The pressurized liquid is discharged after entering the outlet pipe 115.

[0027] When the outlet pipe 115 is connected to the external pipe, the end of the pipe is inserted into the outlet pipe 115. At this time, the end of the external pipe will contact the end face of the stepped embedded interface 221 corresponding to its own diameter. At the same time, the end of the pipe will be embedded in the positioning groove 222. The positioning groove 222 provides a certain degree of limitation for the installation of the pipe. Meanwhile, the sealing ring 223 on the inner wall of the positioning groove 222 will be compressed and deformed to fill the interface gap and prevent leakage. The multi-stage diameter design can be adapted to external pipes with different inner diameters, improve the versatility of the equipment, reduce the use of intermediate connection joints, simplify the installation steps, improve installation efficiency and connection stability, and facilitate later maintenance and repair. At the same time, for pump manufacturers, this design can reduce the number of pump body models. A single pump body can meet the connection requirements of multiple pipe inner diameters, reduce the number of production molds and production costs, and also facilitate inventory management, improve production efficiency and economic benefits.

[0028] After the pipe is installed through the stepped embedded interface 221, the internally threaded extrusion tube 211 is rotated clockwise. A threaded groove adapted to the inner wall of the internally threaded extrusion tube 211 is provided on the outside of the outlet pipe 115. Therefore, when the internally threaded extrusion tube 211 is rotated, it rises axially along the outlet pipe 115. During this rising process, it extrudes multiple support rods 212. At this time, the bottom of the multiple internally threaded extrusion tubes 211 rotates at a fixed point inside the groove 210 via a pin. During the rotation of support rod 212, it drives support rod 213 to move via the sliding groove 219. Support rod 213 then converges with each other through the action of the sliding groove 217 and the limiting groove 214. Simultaneously, multiple... During the convergence of the second support rod 213, the anti-slip arc-shaped clamp 216 will move synchronously. As multiple anti-slip arc-shaped clamps 216 converge, they will clamp and fix the outer wall of the pipe, further reinforcing the pipe and reducing the possibility of loosening or falling off during use. This improves the stability of the equipment during water supply and enhances the equipment's performance. Simultaneously, during the convergence of the second support rod 213, the spring 218 will be compressed through the first slide groove 217. The spring 218 will then contract and store energy under the limiting effect of the limiting ring 215. After disassembling the pipe by rotating the internal threaded compression tube 211 counterclockwise, the second support rod 213 will synchronously drive the first support rod 212 to reset through the rebound force of the spring 218, facilitating subsequent use.
