Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Reference Figures 1-7 As shown, the carbon fiber composite pump provided in this embodiment includes a pump body 100, which is equipped with a pump body 110. The pump body 110 is made of carbon fiber composite material, and the pump body 100 is also equipped with components such as an impeller assembly 120 installed on the pump body 110. The pump body 110 is equipped with a discharge protrusion 112 for discharging material. In this embodiment, the discharge protrusion 112 is made of a first structural layer and a second structural layer. In the radial direction of the discharge protrusion 112, the first structural layer is inside and made of a first material, which is carbon fiber composite material. The second structural layer is outside the first structural layer and is made of a second material, which is a material with greater structural strength than the first material.

[0019] With the above structure, when the discharge convex pipe 112 of the carbon fiber composite pump is subjected to greater pressure, the second structural layer can tighten the first structural layer from the outside, so that the discharge convex pipe 112 can withstand greater pressure, thereby effectively reducing the probability of the discharge convex pipe 112 cracking due to excessive pressure, thus extending its service life, making the carbon fiber composite pump have a lower failure rate during use, reducing production costs, and creating greater economic value.

[0020] Optionally, the second structural layer is a third plate 230 made of steel. The aforementioned discharge protrusion 112 is disposed on the third outer wall of the pump body 110. The third plate 230 is fixedly connected to the third outer wall, and the third plate 230 has a third through hole 231 adapted to the aforementioned discharge protrusion 112. The aforementioned discharge protrusion 112 is inserted into the third through hole 231. In this way, the wall of the third through hole 231 wraps around the aforementioned discharge protrusion 112 from the outside, thereby enhancing the compressive strength of the discharge protrusion 112.

[0021] More preferably, the third plate is further provided with a plurality of third screw holes evenly distributed around the third through hole. The plurality of third screw holes are used to connect the discharge pipe flange. It should be noted that the discharge pipe flange is a structure at the end of the discharge pipe. The discharge pipe flange is fixedly connected to the outer wall of the third plate 230 by a plurality of third bolts and a plurality of third screw holes 232.

[0022] In this embodiment, a third thickened boss 233 is integrally formed or welded to the third plate 230. The third thickened boss 233 is embedded in the third outer wall, and several third screw holes 232 extend into the third thickened boss 233. This extends the length of the third screw holes 232, thereby improving the connection with the third bolts. The third thickened boss 233 can be a ring fixed to one side of the third plate 230. Both the ring and the third plate 230 are fixed to the pump body 110. This not only enhances the connection strength between the third plate 230 and the pump body 110, but also enhances the connection strength between the third thickened boss 233 and the pump body 110, further reducing the probability of displacement of the third plate 230 and the third thickened boss 233 relative to the pump body 110. The third screw hole 232 for installing the discharge pipe flange is actually integrated into the third plate 230 and the third thickened boss 233, so that the discharge pipe flange can be more securely connected to the carbon fiber composite pump provided in this embodiment.

[0023] Optionally, the pump body 110 is further provided with a feed inlet 111, which is used to inject fluid into the pump body 110. The fluid entering the pump body 110 is pressurized by the impeller assembly 120 and then discharged from the discharge convex pipe 112. In this embodiment, the feed inlet 111 is arranged along the axial direction of the impeller assembly 120, and the discharge convex pipe 112 is arranged along the radial direction of the impeller assembly 120. The outer wall of the pump body 110 provided in this embodiment includes a first outer wall, a second outer wall, a third outer wall, a fourth outer wall, a fifth outer wall, and a sixth outer wall. The feed inlet 111 penetrates the first outer wall, and the second outer wall is directly opposite the first outer wall. Optionally, the second outer wall has a mounting port 113 for mounting the impeller assembly 120. The discharge protrusion 112 penetrates the third outer wall, and the fourth outer wall is directly opposite the third outer wall. The fifth and sixth outer walls are directly opposite each other. The fifth and sixth outer walls are both located between the first, second, third, and fourth outer walls. The first, second, third, fourth, fifth, and sixth outer walls constitute the complete outer wall of the pump body 110.

[0024] It also includes a connecting frame composed of a first plate 210, a second plate 220, a fourth plate 240, a fifth plate 250, and a sixth plate 260. The first plate 210, the second plate 220, the fourth plate 240, the fifth plate 250, and the sixth plate 260 are respectively fixed to the first outer wall, the second outer wall, the fourth outer wall, the fifth outer wall, and the sixth outer wall, and the first plate 210, the second plate 220, the third plate 230, the fourth plate 240, the fifth plate 250, and the sixth plate 260 are fixed together. In this way, the first plate 210, the second plate 220, the third plate 230, the fourth plate 240, the fifth plate 250, and the sixth plate 260 form an outer frame 200 covering the pump body 110, thereby strengthening the structural strength of the pump body 110 of the pump body 100. The third plate 230 is also connected to the remaining outer wall of the pump body 110 through the aforementioned connecting frame. This makes the third plate 230 more securely connected to the pump body 110, preventing the third plate 230 from falling off the third outer wall of the pump body 110.

[0025] Specifically, the first plate 210, the second plate 220, the third plate 230, the fourth plate 240, the fifth plate 250, and the sixth plate 260 are all made of carbon steel plates, and are welded together. In this embodiment, the pump body 100 has a square block shape. The first plate 210, the second plate 220, the third plate 230, the fourth plate 240, the fifth plate 250, and the sixth plate 260, after being welded together, form a rectangular frame that encloses the pump body 110. It is worth noting that the pump body 110 is installed in the outer frame 200 by casting, so that the first plate 210, the second plate 220, the third plate 230, the fourth plate 240, the fifth plate 250 and the sixth plate 260 are respectively fixedly connected to different outer walls of the pump body 110.

[0026] Optionally, the first plate 210 is provided with a first through hole 211 corresponding to the feed port 111 and a plurality of first screw holes 212 evenly distributed around the first through hole 211. The plurality of first screw holes 212 are used to connect the feed pipe flange. It should be noted that the feed pipe flange is a structure at the end of the feed pipe. The feed pipe flange is fixedly connected to the outer wall of the first plate 210 by a plurality of first bolts and a plurality of first screw holes 212.

[0027] In this embodiment, a first thickened boss 213 is integrally formed or welded to the first plate 210. The first thickened boss 213 is embedded in the first outer wall, and several first screw holes 212 extend into the first thickened boss 213. This extends the length of the first screw holes 212, thereby better connecting them to the first bolts. The first thickened boss 213 can be a circle fixed to one side of the first plate 210. Both the circle and the first plate 210 are fixed to the pump body 110. This not only enhances the connection strength between the first plate 210 and the pump body 110, but also enhances the connection strength between the first thickened boss 213 and the pump body 110, further reducing the probability of displacement of the first plate 210 and the first thickened boss 213 relative to the pump body 110. The first screw hole 212 for mounting the feed pipe flange is actually integrated on the first plate 210 and the first thickened boss 213, so that the feed pipe flange can be more securely connected to the carbon fiber composite pump provided in this embodiment.

[0028] Optionally, the second plate 220 is provided with a second through hole 221 corresponding to the mounting port 113 and a plurality of second screw holes 222 evenly distributed around the second through hole 221. The plurality of second screw holes 222 are used to connect the bracket 130. Specifically, the bracket 130 is connected to the second plate 220 by screwing the second bolts into the second screw holes 222. The bracket 130 is used to install a power source connected to the impeller assembly 120. It should be noted that the bracket 130 and the power source are both existing technologies, so they will not be described in detail here. The power source can be an electric motor.

[0029] In this embodiment, a second thickened boss 223 is integrally formed or welded to the second plate 220. The second thickened boss 223 is embedded in the second outer wall, and several second screw holes 222 extend into the second thickened boss 223. This extends the length of the second screw holes 222, thereby better connecting them to the second bolts. The second thickened boss 223 can be a ring fixed to one side of the second plate 220. Both the ring and the second plate 220 are fixed to the pump body 110. This not only enhances the connection strength between the second plate 220 and the pump body 110, but also enhances the connection strength between the second thickened boss 223 and the pump body 110, further reducing the probability of displacement of the second plate 220 and the second thickened boss 223 relative to the pump body 110. The second screw hole 222 for mounting bracket 130 is actually integrated into the second plate 220 and the second thickened boss 223, so that the bracket 130 can be more securely connected to the carbon fiber composite pump provided in this embodiment.

[0030] It is worth noting that in the prior art, the pump body 110 of the carbon fiber composite pump has pre-embedded bolts (such as internally threaded pipes or nuts) within its wall. These bolts are used to connect and fasten bolts, which in turn connect the inlet flange, outlet flange, and other external components to the pump body 110. However, the connection area between the bolts and the pump body 110 is relatively small. Therefore, during the operation of the carbon fiber composite pump, these bolts may sometimes loosen within the wall of the pump body 110, resulting in an unstable connection.

[0031] In this embodiment, the first screw hole 212 for connecting the first bolt is provided on the first plate 210, and a first thickened boss 213 for embedding the pump body 110 is provided on the first plate 210, such that the first screw hole 212 extends into the first thickened boss 213; the second screw hole 222 for connecting the second bolt is provided on the second plate 220, and a second thickened boss 223 for embedding the pump body 110 is provided on the second plate 220, such that the second screw hole 222 extends into the second thickened boss 223; the third screw hole 232 for connecting the third bolt is provided on the third plate 230, and a third thickened boss 233 for embedding the pump body 110 is provided on the third plate 230, such that the third screw hole 232 extends into the third thickened boss 233. In this way, the first thickened boss 213, the second thickened boss 223 and the third thickened boss 223 will not rotate within the wall of the pump body 110, and the first thickened boss 213, the second thickened boss 223 and the third thickened boss 233 are all steel components with high strength, so that the first bolt, the second bolt and the third bolt can be connected more reliably.

[0032] Optionally, a first connecting rod 300 is welded and fixed between the first plate 210 and the second plate 220. The first connecting rod 300 is embedded in the wall of the pump body 110, that is, the first connecting rod 300 penetrates the wall of the pump body 110. There are multiple first connecting rods 300, evenly distributed around the impeller, for example, four, six, or eight. The arrangement of the first connecting rod 300 further enhances the connection strength between the first plate 210 and the second plate 220, thereby increasing the structural strength of the entire outer frame 200 and providing greater clamping force to the pump body 110 of the pump body 100.

[0033] The aforementioned first connecting rod 300 can be a solid straight rod. Ideally, the first connecting rod 300 is a hollow rod, that is, a straight tube. This first connecting rod 300 is used to pass through a tie bolt (not shown in the figure), which is used to clamp the first plate 210 and the second plate 220 to the pump body 110, thereby further enhancing the structural strength of the outer frame 200. Thus, in this embodiment, the first connecting rod 300 not only strengthens the structural strength of the outer frame 200 but also provides a passage for the tie bolt.

[0034] Optionally, a second connecting rod 400 is welded and fixed between the third plate 230 and the fourth plate 240. This second connecting rod 400 is embedded in the wall of the pump body 110, meaning it penetrates the wall of the pump body 110. Multiple second connecting rods 400 are evenly distributed around the discharge protrusion 112; for example, there may be four, six, or eight second connecting rods. The second connecting rod 400 further enhances the connection strength between the third plate 230 and the fourth plate 240, thereby increasing the structural strength of the entire outer frame 200 and providing greater clamping force to the pump body 110 of the pump body 100.

[0035] The aforementioned second connecting rod 400 is a hollow rod, that is, it is also a straight pipe. The second connecting rod 400 is used to pass through long bolts (not shown in the figure) that mount the pump body 100 onto an external object. In this way, the second connecting rod 400 in this embodiment not only strengthens the structural strength of the outer frame 200, but also provides a passage for long bolts to pass through.
