Description

Technical Field

[0001] This utility model relates to the field of gear oil pump technology, and more specifically, to a modified low-noise gear oil pump. Background Technology

[0002] In modern industrial production, gear pumps are widely used as important fluid transport equipment in fields such as petrochemicals, machinery manufacturing, and the automotive industry. Their working principle is based on the meshing and disengagement of gears, controlling changes in volume to achieve the intake and discharge of liquids.

[0003] A Chinese patent with publication number CN222296327U discloses a low-noise gear oil pump. The key technical features include: a base mounted on the bottom of the pump body; a positioning block on one side of the base; an oil outlet pipe on one side of the pump body; a cover plate on one side of the pump body; two lead screws inside the cover plate; auxiliary blocks fitted at one end of each lead screw; positioning frames on one side of each auxiliary block; and clamping rings on one side of each positioning frame. By configuring the lead screws, clamping rings, locking strips, a sound insulation layer, and a sound-absorbing layer, rotating two torsion rods sequentially can drive the two lead screws to rotate, allowing the two clamping rings to approach each other. Multiple locking strips are embedded into multiple locking holes. The sound insulation layer is made of sound-insulating felt, capable of isolating, blocking, and separating noise propagating within the pump body. The sound-absorbing layer is made of inorganic fiber material, containing numerous micropores and gaps, which absorb sound and reduce echoes, thus improving the noise reduction performance of the gear oil pump.

[0004] Existing technologies often suffer from the following drawbacks: When the sound-absorbing material inside a low-noise gear pump ages and its sound-absorbing capacity decreases during use, the pump often needs to be disassembled to replace the material, making maintenance complex. Therefore, a modified low-noise gear pump is proposed. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1 and Figure 4 As shown, this embodiment proposes a modified low-noise gear oil pump, including an oil pump body 1. A first mounting box 2 and a second mounting box 3 are fitted onto the surface of the oil pump body 1, and the first mounting box 2 and the second mounting box 3 are tightly fitted together. Polyester fiber sound-absorbing cotton panels 5 are detachably mounted on the inner walls of both the first mounting box 2 and the second mounting box 3. A mineral wool panel 4 is detachably mounted on the side of the polyester fiber sound-absorbing cotton panel 5 closest to the oil pump body 1. Rubber gaskets 6 are fixedly connected to the inner walls of both the first mounting box 2 and the second mounting box 3. The first mounting box 2 and the second mounting box 3 facilitate the replacement of the mineral wool panel 4 and the polyester fiber sound-absorbing cotton panel 5, thereby improving the efficiency of replacing the sound-absorbing material of the oil pump body 1.

[0028] like Figures 2-5 As shown, four clamping plates 9 are mounted on the surface of the first mounting box 2, and four mating plates 12 are mounted on the surface of the second mounting box 3. When installing the first mounting box 2 and the second mounting box 3, the clamping plates 9 and mating plates 12 connect them, ensuring the stability of the installation. Each of the four mating plates 12 has a clamping block 13 fixedly connected to the side near the clamping plate 9, and the clamping block 13 is slidably connected to the inner wall of the clamping plate 9. The clamping blocks 13 restrict the relative position between the clamping plates 9 and the mating plates 12, thus connecting them. Each of the four clamping plates 9 has a first rotating rod 8 fixedly connected to the side near the first mounting box 2, and the other end of the first rotating rod 8 is rotatably connected to the first mounting box 2. A positioning plate 7 is fixedly connected to the side of the second mounting box 3 near the first mounting box 2, and the positioning plate 7 is slidably connected to the inner wall of the first mounting box 2. The first rotating rod 8 ensures a stable connection between the card plate 9 and the first mounting box 2, while allowing the card plate 9 to rotate relative to the first mounting box 2. The positioning plate 7 provides a positioning effect when installing the first mounting box 2 and the second mounting box 3.

[0029] like Figure 2 , Figure 3 and Figure 5As shown, a first torsion spring 10 is fitted onto the surface of the first rotating rod 8, and both ends of the first torsion spring 10 are fixedly connected to the clamping plate 9 and the first mounting box 2, respectively. The first rotating rod 8 can limit the position of the first torsion spring 10, thereby restricting the rotation of the clamping plate 9. Four second rotating rods 11 are rotatably connected to the surface of the second mounting box 3, and the other ends of the four second rotating rods 11 are fixedly connected to the docking plate 12. A second torsion spring 14 is fitted onto the surface of the second rotating rod 11, and both ends of the second torsion spring 14 are fixedly connected to the docking plate 12 and the second mounting box 3, respectively. The second rotating rods 11 and the second torsion springs 14 can limit the position of the docking plate 12 relative to the second mounting box 3, thereby ensuring the stability of the second mounting box 3 during installation as much as possible.

[0030] like Figure 1 and Figure 4 As shown, rectangular plates 15 are fixedly connected to both sides of the oil pump body 1, and several heat dissipation fins 16 are fixedly connected to the side of the two rectangular plates 15 that are far apart from each other. By setting the rectangular plates 15 and heat dissipation fins 16, the heat dissipation speed of the oil pump body 1 can be accelerated as much as possible without affecting the noise reduction treatment of the oil pump body 1.

[0031] Specifically, when using this modified low-noise gear oil pump: When it is necessary to replace the mineral wool board 4 and the polyester fiber sound-absorbing cotton board 5, rotate the clamping plate 9 and the docking plate 12, causing them to drive the first rotating rod 8 and the second rotating rod 11 to rotate on the surfaces of the first mounting box 2 and the second mounting box 3 respectively. This causes the clamping block 13 to move away from the clamping plate 9, releasing the positional restriction of the first mounting box 2 and the second mounting box 3. Move the first mounting box 2 and the second mounting box 3 away from the oil pump body 1, release the clamping plate 9 and the docking plate 12. Under the elastic force of the first torsion spring 10 and the second torsion spring 14, both rotate back to their original positions. Then, replace the mineral wool board 4 and the polyester fiber sound-absorbing cotton board 5 inside them (e.g., ...). Figures 1-5 As shown), the first mounting box 2 and the second mounting box 3 are then moved closer to the oil pump body 1, causing the positioning plate 7 to slide on the inner wall of the first mounting box 2. Simultaneously, the locking block 13 pushes the locking plate 9 and the docking plate 12 to rotate relative to each other. When the rubber pad 6 is close to the oil pump body 1, under the elastic force of the first torsion spring 10 and the second torsion spring 14, the locking block 13 rotates and engages with the locking plate 9, completing the connection between the docking plate 12 and the locking plate 9, thereby restricting the position of the first mounting box 2 and the second mounting box 3 (as shown). Figure 3 and Figure 4 As shown), the rubber pad 6 can improve the stability of the connection between the first mounting box 2 and the second mounting box 3 and the oil pump body 1 (e.g., Figure 2 and Figure 4As shown), during the operation of the oil pump body 1, the rectangular plate 15 and the heat dissipation fin plate 16 can conduct heat away from the first mounting box 2 and the second mounting box 3 and the oil pump body 1, accelerating the heat dissipation rate (e.g., ...). Figure 2 (As shown); the first mounting box 2 and the second mounting box 3 facilitate the disassembly and installation of the sound-absorbing material, thereby improving the replacement efficiency of the sound-absorbing material when it needs to be replaced and simplifying the maintenance work. The rectangular plate 15 and the heat dissipation fins 16 allow the heat generated by the oil pump body 1 during operation to be dissipated to the first mounting box 2 and the second mounting box 3, thus maximizing the heat dissipation effect of the oil pump body 1 (e.g., as shown). Figure 2 and Figure 4 (As shown).

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
